一个实现连接数据库实现登录功能的例子，供大家参考一下。

C#调用Delphi编写的非托管Dll的例子源程序。mydll.dll是使用delphi编写的，参数均为Pchar型。

里面有两个例子 一个是最为简单的界面 显示一个简单的仪表盘，两外一个是加了背景图片的仪表盘 效果非常好看。是我在别人的基础上修改的。里面的源码都就可以修改 在vs2008上编译

vs2010上基于C#编写的简易画板，可画简易图形，擦出，并且在导入图片上绘画

NetworkWatcher Example In this simple program I show how you can use the NetworkWatcher class to discover controllers on the network. It can be a complement to the NetworkScanner class as it will dynamically update with controllers as they are discovered on the network. So if you for example pull your network cable and then reconnect it the controllers will automatically be rediscovered! GuidScan Example In this example I show how you can save already discovered controllers by their so called Guid. These unique identifiers can then be used to connect to the controllers straight away without having to scan the entire network with the NetworkScanner class. DeviceManager Example Here I show how the DeviceManager class can be used to access the device tree of the controller. It is useful to get information about the hardware devices of the controller. It is the same device information you would find in RobotStudio. ControllerBackup Example In this program I show how you can pull a backup from a controller and save it on your local computer.To do this you initiate a backup on the controller, save it remotely and then copy it over to your local computer.
