From: Saint Atique on 25 Jun 2010 05:56 Firstly, as I am novice my questions can be naive. Never mind. What I want to do is: # Check command line arguments # If arguments provide enough information then show the main window to perform some tasks # If command line arguments are not sufficient then I need to show a dialog box so that user can input missing informations, after dialog box is done I will show the main window Now inside ::InitInstance() how will I write to show the dialog box as I cannot use m_pMainWnd as the dialog box is not my main frame window. Please give me hint. Or is it possible to show a dialogbox and then perform operations using another dialogbox without having a mainwindow? With trillions of advanced thanks. -- Saint Atique, Hobbyist MFC Programmer

Then Use AppWizard to create a MFC EXE project which is SDI or MDI. Examine the InitInstance() prduced for both projects. Copy and paste them so that the dialog is first shown, then CMainFrame-based window. -- David

AFAIK, yes, there's no problem whatsoever. You might want to set m_pMainWnd to your dialog while you're running DoModal in InitInstance, but I'd be surprised if that was really necessary. Goran.

CMyDialog dlg; dlg.DoModal(); I do this in my applications, and I have never had any problem with it. -- David Wilkinson Visual C++ MVP

It has nothing to do with the problem. Note that InitInstance is not a global function as you indicate; it is a member of your CWinApp-derived class, that is,it would be CMyApp::InitInstance, not ::InitInstance. **** > >Please give me hint. > >Or is it possible to show a dialogbox and then perform operations >using another dialogbox without having a mainwindow? **** It would depend on the CDialog code and whether or not it requires a main window. If it requiresa a window, then after the main window is created, suppress the ShowWindow call until you are ready to show the window.
