【VC编写日历源码】是一个面向初学者和进阶者的学习资源，它展示了如何使用Microsoft Visual C++（简称VC）来开发一个功能丰富的日历应用程序。这个源代码实例不仅包含了一个美观的用户界面，还提供了多种实用的功能，对于那些想要深入理解VC++和Visual Studio（VS）开发环境的人来说，是一个不可多得的学习材料。 我们要了解VC++。它是Microsoft公司推出的一种集成开发环境，主要用于编写基于Windows操作系统的应用程序。VC++支持C++语言，并且集成了许多高级特性，如面向对象编程、模板、异常处理等。通过VC++，开发者可以创建桌面应用、游戏、设备驱动等，其强大的性能和灵活性使得它在软件开发领域有着广泛的应用。 在这个日历源码中，我们可以学习到如何利用MFC（Microsoft Foundation Classes）库来构建用户界面。MFC是微软为简化Windows API编程而提供的一个类库，它封装了许多Windows API函数，使得开发者可以更方便地创建窗口、控件和对话框。在这个日历应用中，可能会使用到CWnd、CButton、CEdit等MFC类，来实现日期选择、事件添加、月份切换等功能。 此外，源码中可能还包括了事件处理机制，这是VC++ GUI编程中的关键部分。通过消息映射（Message Map），我们可以定义各种控件的响应函数，比如当用户点击按钮时，程序将执行相应的代码。这有助于理解事件驱动编程的概念。 在VS环境下，我们可以通过IDE（Integrated Development Environment）进行项目管理、编译、调试等操作。VS提供了一个友好的图形界面，使得开发者可以方便地组织源代码、设置编译选项、调试运行等，极大地提高了开发效率。 源码中的日历功能可能涉及到日期时间的处理，这可能用到了C++标准库中的``头文件。通过`time_t`、`tm`结构体以及`localtime()`、`strftime()`等函数，开发者可以实现日期的计算、格式化显示等功能。 此外，如果源码包含了一些自定义的控件或特殊的布局，那么可能还涉及到了Windows GDI（Graphics Device Interface）或者GDI+技术，用于绘制日历的外观，包括字体、颜色、图形等。 通过学习这个【VC编写日历源码】，你可以深入理解VC++的GUI编程，掌握MFC的使用，熟悉VS的开发流程，以及了解日期时间处理和图形绘制的基本方法。对于想要提升Windows应用开发技能的开发者来说，这是一个很好的实践项目。不过，实际学习过程中，还需要结合源代码进行阅读和分析，以便更好地理解每一部分代码的作用和设计思路。

VCLZip Native Delphi Zip/UnZip Component! (VCLZip Lite: Version 2.23 April 14th, 2002) (VCLZip Pro: Version 3.10 Buid 1 - November 25th, 2007) IMPORTANT: If installing the registered version, please be sure to always re-install/rebuild the components (VCLZip and VCLUnZip) to the component pallette (or rebuild the design time package) so that the ThisVersion property and any other new properties will be properly updated. If your application still does not run without the IDE, open up VCLZip's package, click on options and look at the Directories/Conditionals tab. If KPDEMO is defined, remove it and recompile the package. ***IMPORTANT: Please remember do not install these components into a package by the name of either VCLZip or VCLUnZip. You will receive an error if you do. PLEASE TAKE A LOOK AT THE "WHAT's NEW IN THIS VERSION" LINK IN THE HELP FILE AS IT HAS CONVENIENT LINKS TO ALL OF THE NEW TOPICS. ==================== Version 3.10 Build 1 - Several bug fixes. - Added support for Delphi 2006, 2007 - Added support for BCB 2006, 2007 - Improved memory performance when working with archives containing extremely high number of compressed files. ==================== Version 3.06 Build 2 Made Delphi 2005 compatible Other assorted fixes ==================== Version 3.05 Build 1 Fixed a lot of incompatabilities between VCLZip and WinZip Other assorted fixes ==================== Version 3.04 Build 1 New ZLib methods for optimized compression and decompression of single entities of data in standard ZLib format, without the overhead of the PKZip format. This is excellent for compression of data to be sent across the net, compressing web pages (http compliant compression), blobs, etc. - ZLibCompressStream - ZLibDecompressStream - ZLibCompressBuffer - ZLibDecompressBuffer - ZLibCompressString - ZLibDecompressString Overloaded TStream Methods for Delphi 4,5, BCB 4, and 5 - UnZipToStream - UnZipToStreamByIndex - ZipFromStream Special OnGetNextTStream Event for Delphi 4,5, BCB 4, and 5 - Allows zipping multiple TStreams in one process - More efficient than calling ZipFromStream multiple times Capability to use the latest version of ZLib 1.2.1. - VCLZip currently uses 1.4.1 by default. - By defining ZLIB121, VCLZip will use the latest version of ZLib which is included with the registered version. Some optimization improvements which should show some improvement in zipping and unzipping speed when using TkpStreams with D4, D5, BCB4, and BCB5. ============ Version 3.03 (VCLZip Pro) - Please test your application thoroughly with this new version of VCLZip Pro. While it has been tested and has even been used in at least two production applications for several months now prior to initial release, there are so many combinations of property settings, environment differences, and ways to use VCLZip that you should always test VCLZip completely in your application before deploying. *** New Zip64 capabilities, properties, methods and events: - Uncompressed, Compressed, and Archive file sizes can be up to 2^63-1 bytes in length. - You can compress up to 2147483647 files into an archive. This is compatible with PKZip's Zip64 format. - If a file does not extend beyond any of the original limitations (filesizes of 4 gig or 65535 files) then no Zip64 format information is included in the archive. - property isZip64 - tells you when you are working with a zip file that is using Zip64 format. Much faster processing due to linking to Zlib object files for compression and decompression routines. Blocked Zip Files (spanned zip archives split onto hard drive) - Now completely compatible with PKZip and WinZip split archives file naming format. - For backwards compatability you can tell VCLZip to use the old VCLZip filenaming format by using the BlockMode property. - New method OnFileNameForSplitPart called just before each split filepart is created. VCLZip supplies a default implementation of this method so for most purposes you won't need your own. - method DefaultFileNameForSplitPart - VCLZip calls this internally if you don't define your own OnFileNameForSplitPart. You can also call it from your own OnFileNameForSplitPart if you wish to add some processing to the default behavior. - property BlockMode - determines whether VCLZip uses PKZip/WinZip standard naming convention or VCLZip classic method. - method DefaultGetNextDisk - VCLZip calls this internally if you don't define your own OnGetNextDisk. You can also call it from your own OnGetNextDisk event if you wish to add some processing to the default behavior. - Properties for controlling which files are zipped... - IncludeHiddenFiles - default False; - IncludeSysFiles: - default False; - IncludeReadOnlyFiles: - default True; - IncludeArchiveFiles: - default True; - Event OnGetNextStream - Allows you to zip from multiple streams when using the ZipFromStream method. This improves performance since repeated calls to ZipFromStream causes the archive to be updated on each subsequent call. - property ThisBuild - Tells you the current build. See also ThisVersion - property OnHandleMessage - Handles interactive messages with VCLZip. There is a default, so you don't need to define your own unless you wish to eliminate interactive messages and handle them on your own. This is helpful if you are using VCLZip as a service or on a webserver for instance. ******** Upgrading existing applications that use VCLZip 2.X ********** For the most part, existing applications will work as-is. Just install VCLZip 3.X and recompile your code. Here are some things to be aware of though... 1) If your app currently creates mmBlock archives (spanned directly to hard drive) and you define your own OnGetNextDisk in VCLZip 2.X, you should move your code from this event that handles mmBlock events to the new event OnFileNameForSplitPart. However, if you simply rely on VCLZip's default OnGetNextDisk then you don't have to worry about this. 2) If your app creates mmBlock archives, the default naming convention has changed to match the PKZip/WinZip standard. If you wish to keep the same naming convention then set BlockMode := mbClassic. 3) OnGetNextDisk and OnPrepareNextDisk events are called for the 1st disk now. VCLZip 2.X only calls these events starting with the 2nd disk. 4) properties CompressedSize[Index], UncompressedSize[Index], ZipSize are now Int64 types. 5) Delphi 4, Delphi 5, BCB 4, and BCB5 are all capable of using the Zip64 format. However they use the TkpHugeStream decendants which act just like TStreams except they handle files/stream sizes larger than 2gig. There is a TkpHugeFileStream and a TkpHugeMemoryStream which should handle 99% of all necessary actions. If you currently work with VCLZip 2.X with TBlobStreams or some other type of streams, you can either define your own TkpBlobStream for instance which inherits from TkpHugeStream, or use the TkpHugeStream.CopyFrom(TStream, Count) and the TkpHugeStream.GetStream: TStream methods to give VCLZip your stream and get it back. Ofcourse when using regular TStream decendants in D4,4,BCB4,and 5, you cannot create Zip64 archives. If you use Delphi 6, 7, or BCB 6, you don't have to worry about any of this as the normal TSTream is used by VCLZip and handles large file/stream sizes. ============ Version 2.23 (VCLZip Lite) Added the OEMConvert property. Filenames stored in a PKZip compatible archive normally go through an OEM conversion to make them ascii compatible. When opening the zip file the conversion is undone. If you do not plan on having other zip utilities opening up your archives this conversion process is not really necessary. Setting this property to False will eliminate this process. The default value for this property is True for normal PKZip compatability. Added OnEncrypt and OnDecrypt events. These allow you to replace the standard pkzip encryption with your own. Data is passed to these events a buffer at a time. Use this with care as this is still somewhat experimental and I'm not sure how useful it is yet. You must make all changes within the buffer sent in to you. Treat the entire file as a stream. Byte for byte replacement only. No additional keys can be saved. Added OnRecursingFile event. Sometimes when using wildcards and recursing directories, there was no reporting of progress. This will be fired each time a file matches as the file list is being built while recursing directories. Added the EncryptBeforeCompress boolean property. The default for this property is False and if left like this VCLZip will behave like normal. If set to True, VCLZip will encrypt each buffer prior to compressing it instead of afterwards. This will cause files to not be decryptable by normal zip utilities thereby adding a bit of extra security. Bugs Fixed: IMPORTANT!!! Behavior of freeing the ArchiveStream (compressed stream) has been modified. VCLZip will now no longer try to free ArchiveStream, you must free it yourself. This was due to a problem where it would be freed automatically if there was a problem with the ArchiveStream when trying to open it as a zip file (possibly corrupt). Best practice is that ArchiveStream should always point toward a TMemoryStream that you create anyway. Modified the SFX code (the code used to create the SFX stub distributed with VCLZip) so that it handles filenames that have been run through an OEM Conversion. The SFX was losing accented characters. This modification means that if you are creating zip files to be used as SFX's you will want to leave the OEMConvert property mentioned above, set to it's default value of True. Modified so that when cursor is changed to hourglass by VCLZip, previous cursor is saved correctly instead of just changing it back to default cursor. Now saves Central Directory Extra Fields correctly. Fixed the SFX code so that it works properly if you use Copy /B to concatenate a zip file to the stub. Due to a Delphi strange behavior sometimes path names for directory only entries would become corrupted. Removed reference to QConsts, replaced with RTLConsts. Sometimes a GPF would result if a corrupt zip file was opened. Using a wildcard in pathname added to FilesList did not work. Using '*.*' as a wildcard in files added to FilesList now is the same as using '*'. VCLZip will now check for CancelTheOperation during initial building of the fileslist instead of just during compression processing. Added a final call to OnTotalPercentDone with 100% because this didn't always happen. Attributes were not getting set correctly for directory-only entries. Fixed a problem that was not allowing ZipComment's to be added correctly to spanned or blocked zip files. Not the same fix as in 2.22. Directories (directory-only entries) were not being restored properly unless DoAll was True. You were unable to delete a directory from which files were recursively zipped until exiting your application. ============ Version 2.22 Now Delphi 6 compatible. New event called {link=93,OnRecursingFile} which gets called as VCLZip recurses directories searching for files that match a wildcard that is entered in the FilesList. This gets called each time a file matches the wildcard. Fixed a bug which kept diskettes from being labeled when creating spanned zip files on WIN31. Fixed a bug which sometimes did not allow zip comments to be added to blocked zip sets. Fixed a bug which caused VCLZip to not properly handle the IncompleteZip exception on spanned zip sets unless you called ReadZip prior to calling UnZip. Version 2.21 (Changes are shown in the build stages as they were implemented) Pre-Release Build 5: When working with temporary files, VCLZip will now rename, instead of copy, the temp file if the destination is on the same drive. This will speed up the adding of files to an existing zip file when the resulting zip file is very large. Pre-Release Build 4: New event called OnPrepareNextDisk which is an event that will allow you, when creating spanned zip files across diskettes, to do things like format a diskette that has just been inserted, or to add or delete files from the diskette before continuing with the zipping process. Fixed a problem that was causing the CancelTheOperation Method to not work properly. Pre-Release Build 3: Fixed bug which caused VCLZip to miscalculate space needed for zfc file if wildcards are put into the FilesList. Fixed bug so you could have FilePercentDone without needing TotalPercentDone when creating spanned zip files Fixed so relative_offset set correctly for spanned zips. Side effect of removing needless write of header. Added code to read local fileheaders if exception thrown when reading a central fileheader. Fixed problem where directories couldn't be created from directory entries because the fullpath wasn't known yet. Result of having moved this code to earlier. Fixed typo in creation of LOC header values which could cause error if reading local headers. Changed so Zip Comment starting position is calculated based on end of central record instead of end of file. Pre-Release Build 2: IMPORTANT: Changed default for FileOpenMode back to fmShareDenyNone as it had been for all but version 2.20. Fixed a problem where drivepart (i.e. C:\) was not being stripped when saving relative paths. Added a BufferedStreamSize property which can increase the speed of creating zips to floppy (and other slow media) dramatically. The new default for this should increase the speed by as much as 3 times, but you can now tweak this especially for your application! Added an ImproperZip property which gets set when VCLZip detects an inconsistency with the zip. This can be useful for detecting when VCLZip was able to open the zip in spite of an inconsistency found. There was no way to know this in the past. Fixed a problem where zip comments in zfc files were not being read correctly. Added a setZipSignatures procedure which allows you to modify the signatures of your zip file. This will cause other zip utilities to not be able to recognize or read your zip files created with VCLZip. Useful if you want to add further security to your zip files. Pre-Release Build 1: Some zip files would not open correctly, throwing an incomplete zip file exception due to an erroneous "extra field length" identifier in headers of some compressed files. These zip files are rare, but a very few people seemed to have several of them. This problem would not affect zip files created by VCLZip, and this problem should only occur in VCLZip 2.20, not in any previous version. If you had Range Checking turned on, VCLZip would get a range check error when using a wildcard that ended with a * as in 'somefile.*'. Under certain circumstances, drive information would not be stripped from path information if zipping recursively (including subdirectories) "Retrying" to zip a file that could not be opened using the OnSkippingFile event would not always work correctly. Creating spanned zip set to floppy should be faster now due to removing a needless header write to disk for each file. VCLZip would not compile correctly with MAKESMALL defined. Added code to make VCLZip work with BCB5. Haven't tested this yet though since I don't have BCB5 myself yet. Added readonly boolean ImproperZip property which will be set to True when some sort of problem is found when opening the zip file, even if recoverable. This property will be enhanced and refined in the future. If KeepZipOpen is set to True, when putting in the wrong disk in a spanned zip set, VCLZip would not always properly close the file on the old diskette before trying to open the file on the next diskette. Added ECantWriteUCF exception which will be thrown if VCLZip runs out of room to write the uncompressed file when unzipping. Timestamp was not being set properly when unzipping readonly files. Moved setting of the timestamp to before the attributes get set. ============ Version 2.20 Changes have been made in the following areas: --Performance There are a few code optimizations that should speed up the zipping process slightly. --Spanned Zip Files A new feature, turned on with the SaveZipInfoOnFirstDisk allows VCLZip to create and read spanned zip files starting with the first disk instead of the normally required last disk of the spanned disk set by saving a Zip Configuration File on the first disk. This feature can be used even if creating the spanned zip file directly to your hard drive. A new property, SaveOnFirstDisk, allows you to save room on the first disk when creating a spanned zip file, to allow room for other files, such as setup programs, data files, or a Zip Configuration File. Spanned zip files can now be directed toward disks greater than 2 gig in size as long as you are using Delphi 5 or BCB 4. --UnZipping The new Selected indexed property offers another way to flag files to be unzipped. Files that have the Selected property set to True can be unzipped using the UnZipSelected method. The Selected property will be cleared (set to False) for each file as it is unzipped, but you can also call the ClearSelected method to clear them all. At anytime the NumSelected property can be checked to see how many files have been selected. Also, the UnZipToBufferByIndex and UnZipToStreamByIndex methods allow you to unzip files specified by their index instead of by name or wildcard. The BufferLength property allows buffered output (buffer smaller than the total uncompressed filesize) when unzipping directly to memory (see UnZipToBuffer and UnZipToBufferByIndex). This will cause the OnGetNextBuffer Event to be called everytime BufferLength bytes have been output by VCLZip. Modified to work in all ways with zip files that have "extra fields" in their headers. These tend to be quite rare, but they do show up from time to time. --Zipping Added a property called FileOpenMode which allows you to define the file open mode for files when they are opened to be zipped. Added a Retry parameter to the OnSkippingFile Event that can be used to re-attempt to open a file for zipping that is open by another process. This gives the chance to close the file and continue with the zipping process rather than having to start over again. Added a ENotEnoughRoom exception which will be thrown if there is not enough room to write to the archive, i.e. out of disk space. The new OnUpdate Event gets fired when updating or freshening an existing archive. It is triggered for each file that already exists in the archive as it is either replaced or kept in the updated archive. The AddDirEntriesOnRecurse will cause separate directory entries to be included in archives when doing recursive zips through subdirectories. --Integrity Checking A new method, CheckArchive, will perform an integrity check on all files in an archive. This is much faster than using FileIsOK on each file if testing all files in an archive with VERY MANY files. Further improved checking for corrupted zip files when opening zip files. --Encryption The following new properties and methods allow lower level work with password encrypted archives: DecryptHeader Gets the decryption header for a particular compressed file in an archive GetDecryptHeaderPtr Same as DecryptHeader but easier to use in BCB. DecryptHeaderByte Method Tests a password against the decryption header found in the DecryptHeader property. GetDecryptHeaderByteByPtr Same as DecryptHeaderByte but easier to use in BCB. --Self Extracting Executables Changes were made to the ZIPSFX32.BIN stub itself: - Modified to work with zip files containing "extra fields" in their headers. - Modified to change mouse cursor to an hour glass during processing. - Check for correct file size is now done automatically - Now uses the end of central and central headers to find the first local header. - Added a progress meter - Better checking for corrupted zip files. - Added an information window that can optionally be shown when the sfx is initially started up. - Added an AutoRun option to make the sfx stub run automatially when double clicked with no other interaction from the user. For the new modified sfx stub, ZIPSFX32.BIN, instead of using kpSFXOpt, you should now use the TSfxConfig component to set the options for the sfx stub. The new sfx can be found in the sfx\ subdirectory as usual and is called ZIPSFX32.BIN and the original sfx can be found in the same subdirectory except it is now called ORGSFX32.bin. Just rename it if you prefer that one (use KPSFXOPT instead of TSfxConfig with the old stub). --Miscellaneous The installation is now easier, atleast for first time installers of the source code. The .DPK files for Delphi and .CPP files for BCB are now included. Now these files simply have to be compiled and that's it. There is a separate option in the installation for installing to the different versions of Delphi and BCB. Added a property called FlushFilesOnClose which will cause all files opened for write by VCLZip to have their disk buffers flushed to disk when closed. Added the capability to delete Selected files from an archive using the DeleteEntries Method. The behavior of the OnInCompleteZip Event has been greatly improved. You can now use this event to ask the user to insert the last disk of a spanned disk set rather than having to handle this situation from outside VCLZip. The register procedures were changed so that the components now get installed to the "VCLZip" tab on the palette. I found that for all but Delphi 1 I had to actually manually move the components to the "VCLZip" tab. You may find that you have to do this too if you have already installed VCLZip before. The components now use new bitmaps in place of the old ones on the component palette. Separated many compiler defines into a new file called KPDEFS.INC. ==================================== Version 2.18: 1) Thanks to the hard work of a fellow registered user, added the capability to remove all dependencies on the Dialogs, Forms, Controls, and FileCtrl units by defining the conditional MAKESMALL, which results in a smaller footprint. This can be quite useful when putting VCLZip into a DLL for instance. In order to make this work, go into your Project | Options and select the Directories/Conditionals tab and enter MAKESMALL in the conditional defines text box. In Delphi you can add this conditinal define to the project options of your application that uses VCLZip and then do a "build all". In BCB you will have to add this to the project options of the package that contains VCLZip and then rebuild the package. If you define MAKESMALL, the only things you lose are: a) ZIP file open dialog box that appears when the ZipName is set to "?" b) Select Directory dialog box that appears when the DestDir is set to "?" c) Changing the cursor to an hour glass during some operations. d) No long filename support in Delphi 1 2) Made VCLZip completely BCB4 compatible. 3) Added some exception handling to KPUNZIPP and KPINFLT, mainly to handle unexpected situations when wrong passwords are entered. This fixes the problem with PRP, the password recovery program. 4) For Borland C++ Builder, changed any COMP types to double, getting rid of the compiler warnings for unsupported comp type. This affects the OnStartZipInfo and OnStartUnZipInfo events, so you'll have to change the comp parameter to double in these events if you use them (in both your header files and in the CPP files). 5) Modified OnStartUnZip event so that FName (the filename of the file that is about to be unzipped along with complete path) is now a VAR parameter and can be modified. This allows you to change the path and name of a file that is about to be unzipped. This is especially helpfull in applications like Install Programs. NOTE: You will need to change your current code to add the VAR to the event definition and implementation if you already use this event in your application. (In BCB, add a & just before the parameter instead of VAR) 6) Moved many type definitions to VCLUNZIP.PAS so that kpZipObj won't have to be included in your USES list. 7) Fixed bug that caused GPF when setting Zip Comment to '' (empty string). 8) Moved strings in VCLZip/VCLUnZip into a string table, making the code size a little smaller as well as making it much easier to localize string information. However you have the option of not using the new string table, for whatever reason, by defining NO_RES in your project options (in the conditional defines text box on the Directories/Conditionals tab). 9) Removed the need for several files. No longer included are kpstrm.res, kpstrm.rc, kpsconst.res, kpsconst.rc, kpstres.pas, and for Delphi 1, kpdrvs.pas. In some cases the need for these files was eliminated and in other cases just rolled into the newly included kpzcnst.rc, kpzcnst.pas, and kpzcnst.res. Definining NO_RES in your project options will elimiate the need for these new files but will make your code size slightly larger and you won't be able to localize your application without changing VCLZip source code. 10) Modified the OnFilePercentDone and OnTotalPercentDone progress events to work better when creating spanned disk sets and blocked zip sets. They no longer report 100% when the compressed file still has to be copied to disk. 11) Added the ReplaceReadOnly property. Setting this to true will allow files with the ReadOnly attribute to be replaced during the unzip process. 12) Added the ifNewer and ifOlder options to the OverwriteMode property. (This had somehow made it into the help file but not into VCLUnZip) 13) Added the SFXToZip method which will convert an SFX file to a regular zip file. The header pointers will be properly adjusted during the conversion. 14) Fixed a problem where the OnGetNextDisk event would always revert to the DefaultGetNextDisk method instead of what you entered into the Object Inspector each time your project was re-opened. 15) Fixed a bug that caused CRC errors when unzipping files from spanned disk sets if they were STORED (no compression) and spanned across disks. 16) Added the OnZipComplete and OnUnZipComplete events. If defined, these will fire at the very end of a zip or unzip operation (after all files have been processed, not after each file). These events will rarely be used since, normally you will be able to do the same thing at the point that the call to Zip or UnZip returns, but these events can be useful when using VCLZip in threads where in certain circumstances the return from the Zip or UnZip methods are not seen. 17) Creation of SFX files has never been easier!!! The addition of the MakeNewSFX method allows you to create Self Extracting Executables without the need to create a zip file first. The files that you specify in the FilesList property will be zipped, using all the normal VCLZip property settings, and the SFX will be created, all in one step! In addition, you can create configurable SFX files using this method, and you can do this especially easy by adding the new unit kpSFXOpt to your application's USES list and using the new 32bit SFX stub that is now distributed with VCLZip. This allows you to easily set things like SFX Dialog caption, default target extraction directory, file to launch after extraction, etc. 18) Fixed a memory leak that only affects applications using VCLZip that are compiled with Delphi 2, and that use wildcard specifications in the FilesList property. Version 2.17a: 1) Fixed a bug that was keeping VCLZip from reading truncated zip files or sfx files that did not have their headers adjusted. 2) Fixed a bug that was causing a directory to be created on the C drive when doing integrity checking with the FileIsOK property. 3) Added {$V-} to kpZipObj.PAS 4) Moved two AssignTo methods to public instead of private in kpZipObj.PAS Version 2.17: 1) Added Memory zipping and unzipping capabilities through the UnZipToBuffer and ZipFromBuffer methods. See the documentation for these methods in the Help File for more information. 2) New FileIsOK Property allows you to check for the integrity of individual files within an archive without actually unzipping the file. 3) Fixed a bug that kept checking of volume labels from working on WIN31 when working with spanned disk sets. 4) Removed all references to ChDirectory so that VCLZip will be more thread safe allowing separate instances of VCLZip in separate threads to be performing zip/unzip operations at the same time. 5) A new public property PreserveStubs allows you to make modifications to sfx archives and have the archive remain an SFX rather than revert back to a normal zip file. 6) Added a default OnGetNextDisk event. If one is not defined, then the default event will be called when the situation arises that a new disk is needed when zipping or unzipping a spanned or blocked zip archive. 7) Added more power to the wildcard capabilities. Now you can qualify the * wildcard character, for instance: * would satisfy any number of contiguous characters as long as they are all a thru e. * would satisfy any number of contiguous characters as long as none of them were a thru e. This allows you to do things like include files in specific direcories into your ExcludeList. For instance: VCLZip1.ExcludeList.Add('c:\test\*.txt') would exclude the zipping of all .txt files in the test directory but not in any subdirectories. 8) Fixed other minor bugs and made other code enhancements. Version 2.16: ***Please be aware that if you currently use the OnSkippingFile event in any of your applications, version 2.16 will require a small modification as this event has an added parameter and one of the current parameters is used a little differently when being called by the zip operation. Please see the help file for more information. 1) The OnSkippingFile Event has been changed slightly, adding a parameter for the filename. 2) OnSkippingFile is now called when a file to be zipped is skipped because it is locked by another application. See the Help File for more information. 3) Fixed a bug with the Exclude and NoCompressList where they were ignoring entries with anything before the extention (i.e. 'somefile.*' as opposed to '*.zip') if you were saving directory information. 4) Fixed a bug that caused an error if you added a wildcard with a non-existent directory to the FilesList. 5) A few other minor bug fixes. Modifications for 2.15 include: 1) PackLevel can now be set to 0 (zero) which means no compression at all (STORED only). 2) New property ExcludeList is a new stringlist that you can add filenames and wildcards to in order to specify files that you do not wish to be included in an archive. 3) New property NoCompressList is a new stringlist that you can add filenames and wildcards to in order to specify files that you wish to be STORED with a PackLevel of 0 (zero), no compression. 4) All compiler warnings and hints were removed. Modifications for 2.14 include: 1) Delphi 4 compatability. 2) Added ability to use complex wildcards when specifying which files are to be zipped. This includes wildcard characters not only in the filename but also in the pathname. This allows you to specify directories using wildcards, for instance: VCLZip1.FilesList.add('c:\test\w*\mycode*.pas'); would get all PAS files beginning with mycode in subdirectories under TEST that begin with the letter w. Wilcards may be much more complex than this. Please see the help file for more information. 3) Added the ability to override the RECURSE property setting when specifying files to be zipped. By adding the following characters to the beginning of the filenames being added, you can override whatever the current setting is for the RECURSE property: '>' will force recursion into subdirectories '|' will force NO-recursion For instance: VCLZip1.FilesList.add('>c:\windows\*.ini'); will get all .ini files in and below the windows directory reguardless of what the recurse property setting is. and: VCLZip1.FilesList.add('|c:\windows\sys*\*.dll'); will get all .dll files in subdirectories of the windows directories that start with 'sys' but will not recurse into any directories below the sys* directories. 4) The [ and ] characters previously used as special wildcard characters have been changed to < and > since [ and ] are valid filename characters. If you still need to use the previous characters for backward compatability, I can show registered users how to easily modify a couple of constants in the source code in order to go back to the old style. See "Using Wildcards" in the help file for more information. 5) A few bug fixes. Modifications for 2.13 include: 1) New property ResetArchiveBitOnZip causes each file's archive bit to be turned off after being zipped. 2) New Property SkipIfArchiveBitNotSet causes files who's archive bit is not set to be skipped during zipping operations. 3) A few modifications were made to allow more compatibility with BCB 1. 4) Cleaned up the Help File some. 5) KWF file now works for Delphi 1 and Delphi 2 again. Still can't get context sensitive help in Delphi 3. 6) Cleaned up some of the code that was causing compiler warnings and hints. Modifications for 2.12 include: 1) Added a TempPath property to allow the temporary files path to be different from the Windows default. 2) Modified VCLZip so that any temporary files that are created receive a unique temporary filename so as not to clash with any other files in the temporary directory. This also allows working with zip files residing in the temporary directory. 3) Fixed a bug in the relative path feature. 4) Fixed a bug that caused a "list out of bounds" error if a file in the FilesList did not actually exist. Modifications for 2.11 include: 1) Fixed password encryption bug for 16 bit. 2) Fixed "invalid pointer operation" when closing application bug. 3) Fixed path device truncation bug which caused inability to modify existing archives in 16 bit. 4) Fixed inability to cancel during wilcard expansion bug. 5) Added capability to better handle corrupted timestamps. 6) Added capability to open and work with SFX files that were created with the COPY/B method (header files not adjusted). 7) Other small bug fixes. I'm still working on a bug which causes a GPF when continually unzipping the same file thousands to millions of times. This mainly affects programs like the Password Recovery Program (PRP) which uses the brute force method of searching for an archive's password. Modifications for 2.10 include: 1) Capability for 16bit VCLZip to store long file/path names when running on a 32bit OS. 2) New property (Store83Names) which allows you to force DOS 8.3 file and path names to be stored. 3) Better UNC path support. 4) Fixed a bug to allow files to be added to an empty archive. Modifications for 2.03 include: 1) Volume labels now get written correctly to spanned disk sets in Delphi 1 for all versions of Windows. 2) Delphi 1 VCLZip now correctly recognizes when it is running on Windows NT. 3) Fixed a problem with zipping files in the root directory when StorePaths = True. 4) File and Zip Comments are now read correctly from spanned/blocked zip archives. 5) Fixed a buf that was causing "Duplicate Object" errors. Modifications for 2.02 include: 1) Fix for file comments which were supposed to be fixed in version 2.01 but weren't. 2) Fix for stream zipping. Version 2.01 would not create a new archive if using a stream. (The Stream Demo now allows creating new zip files to streams too) 3) A few other minor modifications to further solidify the code. 4) A modification to the Zip Utility Demo which allows unzipping from Blocked zip files as if they were single zip files. 5) Added a read-only, published ThisVersion property which reflects the version of the VCLZip/VCLUnZip that you are currently working with. Modifications for 2.01 include: 1) Fixes for exceptions that were caused when CANCELING a zip or unzip of a spanned zip file. 2) Fix for a possible problem when zipping or unzipping a spanned zip file when one or more of the compressed files resided on more than 2 of the spanned parts. 3) Fix for file comments which were broken in version 2.00. Additional features for version 2.00 include: 1) Modify/Add internal file details (filename, pathname, timestamp, comment) for any file while zipping, in the OnStartZip event. 2) Add an Archive Comment while zipping in the OnStartZipInfo event. 3) Delphi 1 compatiblity for VCLZip. 4) Stream to Stream Zipping - Archives themselves can now be TStreams! 5) New Relative Path Information option. 6) Unzip archives that weren't zipped with the Relative Path option turned on as if they had been by determining how much path information to use with the Rootpath property. 7) Modify timestamps for files in existing archives (you could already modify filenames and pathnames for files in existing archives) 8) The OnBadPassword event now allows you to supply a new password and try the same file again when unzipping. 9) Source code has been cleaned up so that it will compile under Borland C++ Builder with no modifications. Also some bugs were fixed, most importantly: 1) An empty file, that had been compressed into an archive would cause any file added to the archive to cause the archive to approximately double in size. Any archives containing empty files are not corrupted, they are OK. This was simply a fix to the way the archive was processed. 2) After creating an SFX file, you had to close the zip file before you could modify it in any way, otherwise a stream read error was encountered. See the Help file for more information on new features. This zip file is part of a self contained installation program. Just run it and the installation program will begin.

在本文中，我们将深入探讨如何使用VC++与MFC（Microsoft Foundation Classes）库中的MSComm控件进行串口通信编程。这个"vc++基于MScomm控件的串口编程实例"是一个实用的示例，它演示了如何创建一个能够接收和发送数据的上位机程序。我们将分析该实例的核心知识点，帮助你理解串口通信的基本原理和实践操作。 串口通信是设备间通过串行接口进行数据传输的一种方式，广泛应用于嵌入式系统和上位机的交互。MSComm控件是VC++中提供的一种简单易用的串口通信接口，它封装了许多底层的串口操作，使得开发者无需深入了解COM（Communications Port）的硬件细节就能实现串口通信功能。 我们需要了解MSComm控件的主要属性、事件和方法： 1. **属性**： - `CommPort`：设置或获取串口号，如COM1、COM2等。 - `Settings`：设置波特率、数据位、停止位和校验位，例如"9600,N,8,1"表示9600波特率，无校验，8位数据位，1位停止位。 - `Input`：读取串口缓冲区的数据。 - `Output`：写入串口的数据。 - `RThreshold` 和 `InputLen`：定义触发OnComm事件的数据量。 2. **事件**： - `OnComm`：当串口发生错误或数据可用时触发，通常用于检测错误和接收数据。 - `CommError` 属性在 OnComm 事件中用于识别错误类型。 3. **方法**： - `SetCommState`：设置串口参数，如波特率、数据位等。 - `Clear`：清除输入和输出缓冲区。 - `GetCommState` 和 `SetCommMask`：用于获取和设置串口状态和中断。 在`CommTest`这个项目中，开发者可能会创建一个MFC对话框类，并在其中添加一个MSComm控件。然后，通过在对话框的初始化函数中设置MSComm控件的属性，如设置串口号、波特率等。在运行时，用户可以通过按钮或其他控件触发发送或接收数据的事件处理函数。 例如，当点击"发送"按钮时，程序会调用一个函数，将用户输入的数据写入到MSComm控件的`Output`属性，从而发送到串口。同时，`OnComm`事件会被用来监听串口活动，当接收到数据时，程序会读取`Input`属性并处理这些数据。 为了调试和监控串口通信，开发者可能会添加日志记录功能，将发送和接收的数据打印到控制台或文件中。这样可以帮助检查数据是否正确传输，并诊断可能出现的问题。 这个VC++的MSComm控件串口编程实例是一个学习串口通信的好材料，它涵盖了设置串口参数、发送和接收数据以及错误处理的基础知识。通过这个实例，你可以了解到如何在MFC应用程序中集成串口通信功能，这对于嵌入式软件开发的上位机编程至关重要。当你理解并掌握了这些概念后，你将能更有效地设计和实现串口通信解决方案。

正则表达式库在编程中扮演着至关重要的角色，特别是在文本处理、数据验证和搜索替换等任务中。这里我们关注的是一个专为Visual C++ 6.0优化的已编译正则表达式库，源自Boost库的一个版本——boost_1_35_0。Boost是一个广泛使用的C++库集合，提供了许多高级编程工具，其中包括对正则表达式的强大支持。 Boost.Regex是Boost库的一部分，它提供了一个符合ISO/IEC TR 19768（也称为C++ TR1）和C++11标准的正则表达式实现。这个库不仅在功能上非常全面，而且在性能上也有卓越表现。它支持基本的正则表达式语法，如字符类、量词、分组、引用、预查等，同时还包含了一些高级特性，如命名捕获组、平衡组和位置匹配。 在VC6.0这样的较旧版本的编译器上使用Boost.Regex可能面临兼容性问题，因为这些编译器可能不完全支持C++11或TR1标准。不过，Boost库设计时考虑了向后兼容性，所以即使在VC6.0这样的环境下，开发者也能利用其提供的预编译库来快速集成正则表达式功能。 压缩包"boost_1_35_Rex_lib"可能包含以下内容： 1. 库文件：编译好的动态链接库（.dll）和静态链接库（.lib），供你在VC6.0项目中链接使用。 2. 头文件：包含了正则表达式的接口定义，例如`#include `，开发者可以在这个头文件中找到所有关于正则表达式的类和函数声明。 3. 可能还有文档或示例代码，帮助用户理解和使用库中的功能。 使用Boost.Regex库的基本步骤如下： 1. 将库文件（.lib）添加到你的项目链接器设置中。 2. 在源代码中包含所需的头文件，例如`#include `。 3. 使用`boost::regex`类创建正则表达式对象，并使用`boost::regex_match`、`boost::regex_search`和`boost::regex_replace`等函数进行匹配、查找和替换操作。 例如，以下代码展示了如何用Boost.Regex进行简单的匹配： ```cpp #include #include #include int main() { std::string input = "Hello, world!"; boost::regex pattern("world"); if (boost::regex_match(input, pattern)) { std::cout << "Match found!" << std::endl; } else { std::cout << "No match." << std::endl; } return 0; } ``` 在实际开发中，Boost.Regex还提供了许多高级功能，如模式修饰符（忽略大小写、多行模式等）、正则表达式对象的构造函数选项、以及自定义匹配算法等。这些特性使得Boost.Regex成为C++程序员处理正则表达式任务的强大工具。 "已编译好的正则表达式库（VC6.0）(boost源码)"为那些仍在使用老版本编译器的开发者提供了一种便捷的方式，使他们能够享受到现代正则表达式库的强大功能，而无需自己解决编译问题。通过这个库，开发者可以高效地实现文本处理任务，提高代码的可读性和维护性。

在VC++ 6.0开发环境中，快速查找文件是一个常见的需求，特别是在处理大量数据或进行系统搜索时。这个例子展示了如何高效地实现这一功能。快速查找文件的关键在于使用高效的算法和有效的数据结构，以减少不必要的磁盘I/O操作，从而提高查找速度。 我们要了解查找算法的基础。在计算机科学中，线性搜索是最简单的查找方法，但效率较低，特别是对于大型文件目录。在VC++中，我们可以使用二分查找、哈希表、B树等更高效的算法来优化文件查找过程。例如，如果文件名是有序的，二分查找可以显著提高查找速度，时间复杂度为O(log n)。而哈希表可以实现近乎常数时间的查找，但需要额外的内存空间。 在这个VC 6.0的例子中，开发者可能使用了一种特定的算法，可能是基于文件路径的分段或者对文件名进行预处理，以加速查找。为了实现这一点，通常会先读取文件夹的文件列表，然后通过定制的算法过滤出目标文件。在程序设计时，可以考虑使用Windows API函数，如`FindFirstFile`、`FindNextFile`和`FindClose`来遍历文件系统。 下面是一些可能涉及的关键步骤： 1. **获取文件列表**：使用`FindFirstFile`和`FindNextFile` API遍历指定目录下的所有文件和子目录。这些函数返回一个文件信息结构，包含文件名和其他元数据。 2. **预处理文件名**：根据需求，对文件名进行预处理，例如，将所有文件名转换为小写或大写，以便不区分大小写的比较。 3. **查找算法**：应用优化的查找算法，如二分查找或哈希查找，与目标文件名进行比较。 4. **显示结果**：一旦找到目标文件，将其路径显示在一个文本框中，这通常涉及到MFC（Microsoft Foundation Classes）中的控件操作，如`CEdit`类。 5. **错误处理**：处理可能出现的错误，如找不到文件、目录不存在或权限问题，确保程序的健壮性。 6. **性能优化**：如果需要频繁查找，可以考虑缓存文件列表或利用多线程技术并行处理，进一步提高查找速度。 在源代码中，`codesc.net`可能是一个包含了实现以上步骤的源文件，具体细节需要查看源码才能了解。理解并分析这个例子，可以有助于提升对VC++文件操作和高效查找算法的掌握，对于开发涉及大量文件操作的项目非常有帮助。

在VC++编程环境中，"鼠标键盘钩子"是一种高级技术，它允许程序拦截并处理其他应用程序的键盘和鼠标事件。这种技术通常用于实现系统监控、输入控制或游戏外挂等功能。在标题和描述中提到的实例，是一个用VC++编写的程序，它可以锁定用户的鼠标和键盘，只有按下Home键时才能解除锁定。 我们要理解“钩子”（Hook）的概念。在Windows操作系统中，钩子是一种机制，允许一个程序监视其他程序的特定事件，例如键盘或鼠标事件。这通过安装钩子函数到系统消息队列来实现，当相应的事件发生时，系统会调用这些函数。 创建键盘和鼠标钩子主要涉及以下步骤： 1. **定义钩子函数**：你需要编写两个函数，一个处理键盘事件，另一个处理鼠标事件。这两个函数将在钩子被触发时被系统调用。 2. **安装钩子**：使用`SetWindowsHookEx`函数来安装钩子。这个函数需要提供钩子类型（WH_KEYBOARD或WH_MOUSE）、钩子函数的地址、一个模块句柄（通常是你的DLL或可执行文件），以及钩子的线程ID。安装成功后，系统会在指定类型的事件发生时调用你的钩子函数。 3. **处理钩子事件**：在你的钩子函数中，你可以检查事件类型并决定如何处理。例如，如果用户按下鼠标或键盘，你可能会选择阻止事件的进一步传播，以达到锁定输入的效果。 4. **卸载钩子**：当你不再需要钩子时，使用`UnhookWindowsHookEx`函数来移除它。这将停止你的钩子函数被调用。 在描述中提到的功能，即“锁定鼠标键盘，按Home解除锁定”，可以通过在钩子函数中添加额外的逻辑来实现。当检测到键盘事件且按键为Home时，可以解除对鼠标和键盘的锁定，恢复正常的输入行为。 在提供的文件列表中，"说明.txt"可能包含了关于如何编译和运行此示例代码的说明，而"KBLock"可能是源代码文件，包含了实现上述功能的C++代码。要深入理解并学习这个实例，你需要阅读源代码，理解其结构和工作原理，以及如何与Windows API交互。 VC++中的鼠标键盘钩子技术是Windows编程的一个重要组成部分，它涉及到系统级的事件处理和进程间通信。熟练掌握这一技术可以帮助开发者实现更复杂的应用场景，如系统监控、自动化测试等。通过分析和实践这个实例，你不仅可以了解钩子的工作原理，还能提升你的Windows API使用技能。
