class CTestDlg : public CDialog
{
...
protected:
CBrush m_brush;
...
};

BOOL CTestDlg::OnInitDialog()
{
...
m_brush.CreateSolidBrush(RGB(255, 255, 255)); // color white brush
...
}

HBRUSH CAboutDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
/*
** No need to do this!
**
** HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
*/

/*
** Return the white brush.
*/
return m_brush;
}

The above code will not the desired result.
You need to :
a - Return the brush in CTestDlg::OnCtlColor and not in
CAboutDlg::OnCtlColor.
b - check the nCtlColor parameter, that indicates which
control asks for the brush to paint itself. You should
check for the value that indiactes the Dialog window itself, not one of the child conrols in it (I forgot the value name, you can check it in the Help item of OnCtlColor.

For an MFC Dialog, you have 2 .cpp files (Thing.cpp and ThingDlg.cpp). The following line goes in ThingApp::InitInstance() in Thing.cpp:

SetDialogBkColor(RGB(0,0,0), RGB(255,255,255));

The first arg is the background, the second is the foreground. Hope this helps!
