Change the background color

[m_mun]

Hi, I have developed a SDI application and split it into two parts. One part is simple view and another part is form view, in which i have select a dialog as child. My problem is, I can't change the background of dialog and some 'static text' controls color. I have used

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

in app class. But its not working. Pls hlp. Thanks in advanced

To change the color of a static control do that in WM_CTLCOLOR [^]message

Hi, Not only controls color, but also want to change the background color

Create a solid brush in FormView's OnInitialUpdate m_wndbkBrush.CreateSolidBrush(RGB(0,255,0)); , and use this in OnEraseBkgnd overload of FormView.

void CxxxFormView::OnEraseBkgnd(CDC* pDC)
{
CFormView::OnEraseBkgnd(pDC);
CRect rect;
GetClientRect(rect);
pDC->FillRect(&rect, &m_wndbkBrush);
return TRUE;
}

Whenever i scroll down, the other portion does not changes. How can i do that? I have used

void Cxxx::OnDraw(CDC* pDC)
{
CFormView::OnEraseBkgnd(pDC);
CRect rect;
GetClientRect(rect);
pDC->FillRect(&rect, &m_wndbkBrush);
return;
}

Madhu already mentioned that you must do this in OnEraseBkgnd instaed of OnDraw()

You do not call this within OnDraw().

As Madhu mentioned, WM_CTLCOLOR is not only for controls, but also for the dialog. When the wParam is CTLCOLOR_DLG, you can return a brush for dialog box color. Please read the documentation. It says it all.

I have created a new class for form view. There is no msg handler for OnEraseBkgnd

OnEraseBkgnd() is the message handler for WM_ERASEBKGND.
