one simple way insert this codes in your file(I think you need to learning VC)but anyway for solve your problem use this in header file afx_msg BOOL OnEraseBkgnd(CDC* pDC); in cpp file insert BOOL your class name::OnEraseBkgnd(CDC* pDC) { // TODO: Add your message handler code here and/or call return CDialog::OnEraseBkgnd(pDC); }_**

You should open your dialog in dialog editor and then click on caption bar of your dialog. Then go to View --> Properties Window, activate the panel with Windows messages by clicking a toolbar button. Then select WM_ERASEBKGND event and add the handler. The simplest handler can look like this:

BOOL CMyDialog::OnEraseBkgnd(CDC * pDC)
{
	pDC->FillSolidRect(0, 0, 32000, 32000, RGB(0, 0, 255)); // blue
	return TRUE;
}

Depending on the class type (e.g. Dialog, MDI Child Frame, etc.), ClassWizard filters the messages. To show all messages do the following:

select "Class Info" tab;
from "Message filter" combo box, choose "Window";
go back to "Message Maps" tab; now all available messages are displayed in the "Messages" list.
