    It is a Modal dialog. What i mean is when i call DoModal(), it comes to OnDestroy() member function of the dialog window.

        It crashes at: hWnd = ::CreateDialogIndirect(hInst, lpDialogTemplate, pParentWnd->GetSafeHwnd(), AfxDlgProc); in DLGCORE.CPP hInst,lpDialogTemplate has the proper values. pParentWnd=NULL; AfxDlgProc has some value. After this it will go to OnDestroy() instead of OnInitDialog()

                    What kind of controls do you have embedded in this dialog? I seem to remember the need to initialize support for RichEdit Controls prior to their use in a dialog. Best Regards, Bill

                      what i meant by enumerting the cases was that if you do not create the dialog box within if condition then the WM_DESTROY will get generated and it will destroy you dialog box. if you don't wanna use if condition to create a dialog box then you will have to allocate memory to the dialog box pointer with new opeator. i hope this solves your prob.
