Add the definitions inside your class

[DllImportAttribute( "User32.dll" )]
private static extern int FindWindow( String ClassName, String
WindowName );
[DllImportAttribute( "User32.dll" )]
private static extern int SetForegroundWindow( int hWnd );
//to activate an application
int hWnd = FindWindow( null, "This is my Application Title" );
if( hWnd > 0 )

Appactivate(AcadApp.caption);

当在用户桌面上有一个资源管理器时，这种方法不起作用/>
窗口打开，标题与应用程序标题相同。
