Please specify in detail , whether it is a Modal or Modeless dialog , and what do u mean by When u DoModal it sends WM_DESTROY message. Abhishek Srivastava Software Engg (VC++) India ,Noida Mobile no 9891492921 :)

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

Press F9 on destroy, press F5 and then open the callstack and check what's happening Papa while (TRUE) Papa.WillLove ( Bebe ) ;

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()

Can you call GetLastError and see the error string? Papa while (TRUE) Papa.WillLove ( Bebe ) ;

Hi, case 1 CDialog oCDialog; if(oCDialog.DoModal()==IDOK) { } case 2 CDialog *pCDialog; pCDialog = new pCDialog;

I had used case 1.

Did u change the resource file just before it started crashing? Papa while (TRUE) Papa.WillLove ( Bebe ) ;

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.
