I have a Slider Control on a Dialog Box.I want to Change the BackGround Color of Dialog Box whenever the Slider is scrolled.Could anyone point out how to achieve this?

A_Laxmancreate the brush using the slider pos in OnPaint message and fill the Client area Rect of the Dialog.

HBRUSH CtestMFCDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)<br />
{<br />
	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
	// TODO:  Return a different brush if the default is not desired<br />
	return CreateSolidBrush(RGB(0,0,0)); //my brush here set any RGB value here.<br />
}
