如何使CProgressWnd对象的取消按钮起作用？

Question

我的代码是这样的

CProgressWnd progress(AfxGetMainWnd(),_T("进度条"));
 progress.GoModal();
 progress.SetRange(1,1000);
 progress.SetStep(10);
 progress.PeekAndPump();

progress.EnableOnCancelBtn();

 int i;
 for(i=0;i<100;i++)
 {
  progress.StepIt();
  Sleep(1000);
  if(progress.Cancelled())
  {
          progress.DestroyWindow();
         return;
  }
 }
 progress.DestroyWindow();点击“取消”按钮，确不起作用，这是怎么回事？

不清楚您的CProgressWnd类里具体的是怎么实现的？您Debug下单步调试一下看看
