推荐答案

您的问题对我来说还不太清楚，但根据我的意思，您想采用以下解决方案...
在显示到消息框之前，请调用对话框的OnCancel()方法，并从消息框返回控件后，请使用对话框的DoModal()方法.

Your question is little unclear to me but according me you want following solution...

Before showing to message box call OnCancel() method of dialog box and after returning the control from message box use DoModal() method of dialog box.

首先，如果您调用消息框在OnOk()
然后

Hey first thing That if you called message box on OnOk()
then

void YourDialog::OnOk()
{
  AfxMessageBox("HELLO");
  OnOk();
}

然后它显示消息，并且Di8alog将不可见，
所以
对于显示消息框后保留在同一对话框中，请删除OnOk();

Then it display message and Di8alog will invisible,
So
For Remain in Same dialog after displaying messagebox please remove OnOk();

void YourDialog::OnOk()
{
  AfxMessageBox("HELLO");
  //OnOk();

}

现在，如果要隐藏对话框，则只需调用OnCancel()或OnOk();
如果无法理解，那么请在执行所有这些活动的地方提供代码块.

Now if you want to Hide the dialog then just Called OnCancel() or OnOk();
If Not understand then please provide your code block where you doing all this activities.

我想您正在关闭对话框，因此showwindow无法正常工作，因为您应该通过以下方式再次创建对话框DoModal或其他方法...

如果您通过按确定"或取消"按钮来执行此操作，则可以执行第二个解决方案上发布的操作，或者创建具有所需特定功能的另一个按钮...这可能会更清楚，您可以使用确定/"如果在未知的将来需要它们，请取消按钮...

如果您按下另一个按钮，则始终可以:

1.隐藏对话框(显示窗口...).
2.创建消息框.
3.显示对话框(显示窗口...).

HTH！

I guess you are closing the dialog and therefore showwindow won''t work because you should create the dialog again via a DoModal or another method...

If you are doing that via pressing the OK or CANCEL buttons, then you could do what has been posted on the second solution or create another button with the specific functionality you need... which probably would be clearer and you could use the OK/CANCEL buttons if they are needed in a unknown future...

If you make another button, you can always:

1. hide your dialog (showwindow...).
2. create the messagebox.
3. show the dialog (showwindow...).

HTH!
