Hi Chris,

if iMsg = WM_CREATE then
  Editbrush = CreateSolidBrush(16777215) 


    elsif iMsg = WM_CTLCOLOREDIT then
          if lParam = EditContol then
              SetBkColor(wParam, 16777215) 
             return Editbrush
          end if
    elsif iMsg = WM_CTLCOLORSTATIC then
          if lParam = EditControl then
             SetBkColor(wParam, 16777215)
             return Editbrush
          else
             return 0
          end if    
    elsif iMsg = WM_CTLCOLORLISTBOX then
          SetBkColor(wParam, rgb(5, 5, 192))
          return Editbrush

remember this Chris, you have to return the brush itself.......
16777215 is white I think so you'll need to change this to the 
color you want.

WM_CTLCOLORSTATIC is for readonly MLE's
WM_CTLCOLOREDIT  is for non readonly MLE's
WM_CTLCOLORLISTBOX is for the listbox's

actually, SetBkColor(wParam, 16777215) in each of these
is for your next question you might have on the colors of Edit
controls..... just jokin'

Hope it helps,
Euman
