How do you change the backcolor of a dialog box using setbkcolor()? I not know how to get the first parameter "hdc" for this function.  Please show me how to implement this in a OnInitDialog() call.

If you really want to change a dialog's background color, write your handler for WM_CTLCOLOR and return the brush you want.

Example:  set your dialog's background to white.
HBRUSH CMyDlg::OnCtlColor(...)
  {
    return (HBRUSH)GetStockObject(WHITE_BRUSH);
  }

The HBRUSH example works great, but for future reference -

To use:
GetDC()->SetBkColor(RGB(255,255,255));

Don't I need to first define a pointer to the CDC like:
CDC* pDC = GetDC():

Yeh, if you want to have several operations on the DC, you should store the DC pointer first.
