调用CloseHandle(hBitmap)时报错： 0xC0000008: An invalid handle was specified
改为FindClose(hBitmap); 就可以了
这是msdn上关于CloseHandle的注释：
If the application is running under a debugger, the function will throw an exception if it receives either a handle value that is not valid or a pseudo-handle value. This can happen if you close a handle twice, or if you call CloseHandle on a handle returned by the FindFirstFile function instead of calling the FindClose function.
如果你是使用 CloseHandle 来关闭一个用FindFirstFile这个方法返回的Handle，就应该使用FindClose 这个方法来替代
