its handle to the brush object. Refer CBrush class for more details.
Sample,
CBrush m_brDlg;
m_brDlg.CreateSolidBrush( RGB(...) );
(HBRUSH)m_brDlg
m_brDlg.DeleteObject();

Handle returned by this method would not be valid, as it goes out of scope.
Need to use win32 API CreateSolidBrush and return HBRUSH.

Sorry i didn't mention its a member, but the sample code has naming convention, which will say that m_brDlg is a member to the dialog class.
Sorry once again to miss out the point...

I have implement the below code in OnCtlColor but still the colour is not changed.
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
// TODO: Change any attributes of the DC here
CBrush m_brush;
m_brush.CreateSolidBrush( RGB(255,0,0) );
if (CTLCOLOR_DLG == nCtlColor)
return m_brush;
// TODO: Return a different brush if the default is not desired
return hbr;

You need to show code, where this error is occuring.
Instead of clustering this thread, start new thread for this question.

Refer MSDN. You have missed this line for varius controls,
CTLCOLOR_BTN Button control
CTLCOLOR_DLG Dialog box
CTLCOLOR_EDIT Edit control
CTLCOLOR_LISTBOX List-box control
CTLCOLOR_MSGBOX Message box
CTLCOLOR_SCROLLBAR Scroll-bar control
CTLCOLOR_STATIC Static control

1. Book[^] by Don Box.
2. Inside COM[^] by Dale Rogesron.
Additionally refer beginner[^] section on CP.

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.

No its a leake...
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...

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
