Which IDE you are using ? It works great for me on VC6 and VS2005.

As told you already, you need to ask such questions to article authors.

Your dialog's OnCtlColor should look like this,
HBRUSH CMyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if (nCtlColor == CTLCOLOR_DLG)
{
hbr = CreateSolidBrush(RGB(0,45,23));
}
return hbr ;
}
Remember to do this by adding WM_CTLCOLOR handler thorugh class wizard.

Check the GDI objects in task manager. Its keep on increasing when you move any window(task manager window itself) over the dialog. But if you return the HGDIOBJ of member variable, then the count remains same...

You called the SetDialogBkColor() above the line
int nResponse = dlg.DoModal(); isn't it? not below na ?

I implemented the code in initinstance for changing the formview colour and if possbile the mainframe colour..
The code in Initinstance
if (!ProcessShellCommand(cmdInfo))
return FALSE;
// The one and only window has been initialized, so show and update it.
SetDialogBkColor(RGB(255,200,100), RGB(1,1,1));
m_pMainWnd->ShowWindow(SW_SHOW);
m_pMainWnd->UpdateWindow();

ops I though its a dialog based application. In this case(SDI or MDI ) you need to handle the WM_CTLCOLOR message

Thanks.It works

This function is obsolete now, use method suggested by parthi or you can handle WM_CTLCOLORDLG for this,too.

I found this paragraph in MSDN:
Most drawing in a framework program—and thus most device-context work—is done in the view’s OnDraw member function. However, you can still use device-context objects for other purposes. For example, to provide tracking feedback for mouse movement in a view, you need to draw directly into the view without waiting for OnDraw to be called.
In such a case, you can use a CClientDC device-context object to draw directly into the view.
So I'd like to know what's the exact meaning of this paragraph and if there's some code to reference.

It means you can create a CClientDC and draw onto the view, this will then be lost when the view refreshes.

Suppose you are running a application like mspaint and draawing a line, the line need to be updated on every mouse move. This can be done in the mouse mouve message itself. No need to wait for the paint message
SomeClass::OnMouseMove()<br />
{<br />
....<br />
CClientDC dc(this);<br />
dc.MoveTo(...);<br />
dc.LineTo(...);<br />
}

There was a project desighned using VC6.

An assertion failure without the context (surrounding code) is meaningless. Often there is a comment in the source near the assertion that explains the problem or it is obvious from the context. Can you post the code surrounding the ASSERT statement?

If you see at the call stack, it would tell you exact reason for falure. And we could not guess it.
