      The error is very probably in your DLL showing a dialog. Common sources are forgetting to release DCs and GDI objects.

        You probably need to do some serious debugging, firstly to find out why and where this message is produced.

          Sorry, but I don't want to write your code. I - and most others here - just enjoy helping. The design of your application is definitely broken. That is your problem. Tampering with the existing code is the wrong way. Reconsider the design. Read about dialogs hosting user controls.

              And what does that tell us? Pretty much nothing. You need to look at your code where this error occurs and find out what your program is doing, or trying to do: that is where the error lies.

                I have got the problem I have implemented the PrecreateWindow for my view class. just check this code. [code] BOOL CMyView::PreCreateWindow(CREATESTRUCT& cs) { cs.lpszClass = ::AfxRegisterWndClass(CS_HREDRAW | CS_VREDRAW | CS_DBLCLKS | CS_OWNDC,::LoadCursor(NULL, IDC_ARROW), NULL, NULL); cs.style |= WS_CLIPSIBLINGS | WS_CLIPCHILDREN; cs.dwExStyle = WS_EX_CLIENTEDGE; return CView::PreCreateWindow(cs); } [/code] If I remove the first line, i.e cs.lpszClass = ::AfxRegisterWndClass(CS_HREDRAW | CS_VREDRAW | CS_DBLCLKS | CS_OWNDC,::LoadCursor(NULL, IDC_ARROW), NULL, NULL); then my dll window is coming all the times from the client call. But it's flickering . So now please help me what can I do to resolve this. I think some of you must have understood the problem, please help me. Thanks a lot.
