The solution is to not use a

No. You must solve the problem. It's not my job. The only thing I can do, is to help you.
i wanted a view on the dialog. so i derived from cview and created the view in the dialog. 1st time everything is coming fine. but without closing the client application if i try to launch again the dialog then it's giving error. Please give me some suggestion how can i get rid of it. Thanks

The problem is that the view is not properly closed. But even if you would close it properly, there will be other problems. A
CViewis not designed to be a child view of a dialog. It must be a child of aCFrameWndderived class. Change yourCViewclass to be based on aCWnd. -

The error is very probably in your DLL showing a dialog. Common sources are forgetting to release DCs and GDI objects.
Can u give me your mail id so that I can send you the project. Can u help me ?

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.

it's giving this error First-chance exception at 0x7c812afb in TestRev.exe: Microsoft C++ exception: CResourceException at memory location 0x0012ed28.. Crashing in wincore.cpp -- AfxRegisterClass(WNDCLASS* lpWndClass)

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.
