CWnd* pTmpMainWnd = theApp.m_pMainWnd; CSingleDocTemplate* pDocSOTemplate; pDocSOTemplate = new CSingleDocTemplate( IDR_MAINFRAME, RUNTIME_CLASS(CSaveImageOptionDoc), RUNTIME_CLASS(CSaveImageOptionFrame), RUNTIME_CLASS(CSaveImageOptionView)); theApp.AddDocTemplate(pDocSOTemplate); theApp.m_pMainWnd = NULL; pDocSOTemplate->OpenDocumentFile(NULL, FALSE); ASSERT_KINDOF(CSaveImageOptionFrame, theApp.m_pMainWnd); CSaveImageOptionFrame* pMainFrame = static_cast<CSaveImageOptionFrame*>(theApp.m_pMainWnd); theApp.m_pMainWnd = pTmpMainWnd; pMainFrame->ShowWindow(SW_SHOWNORMAL); pMainFrame->CenterWindow(pTmpMainWnd); CSaveImageOption(fram/doc/view) is new SDI i want to creat. in new SDI view i have IDD = IDD_DIALOG wwhich is valid dialog. with DS_SETFONT | DS_FIXEDSYS | WS_CHILD | WS_SYSMENU ita crashes on CFormView :: CFormView () ASSERT_VALID_IDR(nIDTemplate) where nIDTemplate is my IDD_DIALOG i have passed. i knw this may nt be enought info but if nyone has ny idea plz help/

I would suggest making a new blank project using appwizard - and make sure that compiles nicely. Then start changing things little by little. Not a very exciting answer, but you should learn a lot in the process! Good luck, Iain.

Set the no-fail-create style on the dialog, which helps a LOT for diagnosing dialog problems. Are you adding any odd controls? ActiveX thingies? Iain.
