如何在无模式对话框中检查是否单击了按钮

Question

I created main dialog and call no modal dialog, how can i check in main dialog that button is clicked in no modal?

For example if i call modal i can check like this:

Dialog Dlg;
int DlgResult = static_cast<int>(Dlg.DoModal());

if (DlgResult== IDOK)
{                               
   //do smth.
}

Answer 1

如果它是自定义对话框，则一种方法是在非模式对话框关闭时使用SendMessage()或PostMessage()将结果发送到主对话框。

Answer 2

Even after the window closes, you will still have access to the C++ object representing the dialog. You can override OnOK and OnCancel and have them save a flag in the object.
