Reopening a modal dialog in MFC

Question

I need to open a dialog box created from the same class twice. When i try this

CdelmeDlg dlg;
dlg.DoModal();
dlg.DoModal();

The second call opens the dialogue only for a split second, then it closes. My bet was that there is a message remaining in the message queue, so I added this between calls

MSG msgCur;
while (::PeekMessage(&msgCur, NULL, NULL, NULL, PM_REMOVE))
    ;

This solves the problem, but it seems like the wrong thing. Is there a way to properly handle the remaining message?

Answer 1

Do not call EndDialog (IDOK);

To process the pressed ok or cancel buttons, simply inherit OnOk or OnCancel ... Otherwise, EndDialog is called twice and you get the problem you get!
