why do you want to do such a thing?
The two controls are of different type after all.
I guess, you want to have a functionality of CListBox and COwnerDrawListBox. Is it right? If affirmative you can simply override some functions in the derived class.
Some things seem HARD to do, until we know how to do them.

Wheres problem did you use of debugger hwnd is null or hdc?

hWnd and hdc is pointing to some value, not NULL.

1/ try using a more helpful subject than "hi". Though it's polite at least!
2/ what kind of window is it?
3/ is it in your own source code, or do you mean someone else's window?

What kind of window you are creating?
If it is a predefined window (like, edit, static, etc.) then there are specific ways for that.
If not, you can use SetClassLong with GCL_HBRBACKGROUND to change the background color.

Sure why not. If you don't know how include files work then you need better study material for learning how to program in C/C++. You are using one or more books that are introductions to C/C++ to learn from yes?

Hi,
I have a application that communicates with server (Java) and communication is done using SOAP. I am able to communicate properly as much as I can in DEBUG mode but the same code is not running in RELEASE mode.
There is one function (freememory(PBYTE&)) which we are calling to free the memory. this works fine in DEBUG mode but not in RELEASE. if I put message box in this function then it is working fine.
Please suggest I do not want to use messge box.
Thanks

void CTestView::OnPaint()
{
CPaintDC dc(this); // device context for painting
Invalidate(FALSE);
}
void CTestView::OnDraw(CDC* pDC)
{
CTestDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here
CFont font;
font.CreatePointFont(20, "Garamond");
CFont *pFont = pDC->SelectObject(&font);
pDC->TextOut(20, 18, "Christine", 9);
pDC->SelectObject(pFont);
font.DeleteObject();
}
In the above code, even though I am calling Invalidate inside OnPaint(), it is not getting inside the OnDraw(). Pls suggest me some ways how to get inside OnDraw()
