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.
