Do you have the source code? If not, you must contact the supplier of the DLL. If yes, you must check the code.
If the code uses GetDC() somewhere, ensure that ReleaseDC() is called when the CDC is no longer used.

I am releasing it in the ::OnDestroy() fucntion of the view
|
|
|
|
|
That's one place where you release a DC (in your app or the DLL?). If not in the DLL, you should concentrate on the DLL code. There may be multiple places in your code using DCs and GDI objects. If you miss any release call or forget to de-select GDI objcets out of context, the error may occcur.
I can't really help you without seeing the code. I can only guess.
Check this example code:
CDC *pDC = GetDC();
CPen NewPen(PS_SOLID, 0, m_Color);
CPen *pOldPen = pDC->SelectObject(&NewPen);
CFont *pOldFont = pDC->SelectObject(m_pMyFont);
...
pDC->SelectObject(pOldFont);
pDC->SelectObject(pOldPen);
ReleaseDC(pDC);

I am not able to delete the view it's crashing
delete m_pNewView;
It's crashing. how can I delete the view.????
|
|
|
|
|
I'm sorry, but without knowing your code, I can't really help. Also, is there a relation to the original question, or is it a new one? If it is a new one, you should open a new question.
Views are usually handled by the document class and the frame work. To close a view manually, the parent frame of the view must be closed.

I'll reply again to this message. You have added too much unformatted code to your other posts (therefore somebody has donevoted them).
- You should use the 'code' button on top of the CP message input window to format the selection as C++ code.
- You should limit the amount of code. Nobody here will step through too many lines.
Regarding the CView deletion:
Why do you use a CView derived class within a CDialog? Using a CWnd derived class as user control should solve your problem. CView classes are used with the document view model and expect to have a frame window as parent.

The solution is to not use a CView derived class as a client window of a dialog.

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 CView is not designed to be a child view of a dialog. It must be a child of a CFrameWnd derived class. Change your CView class to be based on a CWnd.

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

it's giving this error

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.

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.

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.
