Form窗体无响应not responding，白板的解决补丁

用过AX的都知道，在进行一个大的操作时，如果无法立刻执行完成，那运行这个操作的过程经常出现的就是系统的大白板，系统系统窗口没有响应，就算是加了进度条，也是一样没有响应，这样用户就无法查看当前操作的运行进度，通过下面的补丁就可以解决这个问题

在WinApi类中增加方法

 1 /// <summary>
 2 /// Call user32.DisableProcessWindowsGhosting
 3 /// </summary>
 4 /// <remarks>
 5 /// Disables the window ghosting feature for the calling GUI process. Window
 6 /// ghosting is a Windows Manager feature that lets the user minimize, move,
 7 /// or close the main window of an application that is not responding.
 8 /// </remarks>
 9 public static client void disableProcessWindowsGhosting()
10 {
11     DLL         dll     = new DLL(#UserDLL);
12     DLLFunction dllFunc = new DLLFunction(dll, @"DisableProcessWindowsGhosting");
13     ;
14     dllFunc.returns(ExtTypes::void);
15     dllFunc.arg();
16 
17     dllFunc.call();
18 }

在info.startupPost()中添加调用

 1 /*
 2 No SYS code must exist in this method
 3 */
 4 void startupPost()
 5 {
 6     if (clientKind() == ClientType::Client)
 7     {
 8         // BP deviation documented
 9         WinAPI::disableProcessWindowsGhosting();
10     }
11 }

这个补丁需要操作系统WIN XP SP3 或者WIN2003 SP2以上才能支持
