推荐答案

由于记录的SetSystemCursor（）函数已经破坏了通过光标，再次摧毁它不会有任何效果。

As documented, the SetSystemCursor() function already destroys the passed cursor so destroying it again isn't going to have any effect.

您需要存储旧光标的副本，这样你就可以在以后恢复它：

You'll need to store a copy of the old cursor so you can restore it later:

// Global Variables:
HCURSOR hOldCursor;
...
   hOldCursor = CopyCursor(LoadCursor(NULL, MAKEINTRESOURCE(IDC_ARROW)));
   HCURSOR hNewCursor = CopyCursor(LoadCursor(hInstance, MAKEINTRESOURCE(IDC_MYCURSOR)));
   SetSystemCursor(hNewCursor, OCR_NORMAL);

和这样的恢复：

SetSystemCursor(hOldCursor, OCR_NORMAL);
DestroyCursor(hOldCursor);
hOldCursor = NULL;

请注意你的事业时，你的程序没有恢复光标终止相当大的痛苦。由于经历了由我测试这个code。更改系统光标是非常不友好的，因为它有可在桌面上运行的所有其他程序的全球影响。

Note the considerable pain you cause when your program terminates without restoring the cursor. As experienced by me testing this code. Changing system cursors is quite unfriendly since it has a global effect on all other programs that run on the desktop.
