This is a simple problem but for some reason it's annoying me... I have a few static controls on my window, and I've changed the background window colour to a nice pale blue colour... However the background behind the lettering of the text in each static control is still painted in the original colour... According to the Platform SDK, I have to handle the WM_CTLCOLORSTATIC message, which can be used to set the background colour. So this is what I have:

  
// g_App.GetBckBrush() returns the HBRUSH I'm using.

// rcRect is just a RECT structure.

case WM_CTLCOLORSTATIC:
    // A static control is about to be drawn...

    GetWindowRect((HWND)lParam, &rcRect);
    FillRect((HDC)wParam, &rcRect, g_App.GetBckBrush());
    return((LRESULT)g_App.GetBckBrush());

... but when I do that it redraws the background behind the text as plain white, whatever brush I supposedly paint it with in this snippet of source code. Weird. Have I missed something? Thanks, ======== Smidge ======== Edited by - smidge_tech on December 26, 2001 10:24:55 AM

You can try finding where MFC registers the window class, and use your brush instead of the default one there...

try this (works for me):

  
// g_App.GetBckBrush() returns the HBRUSH I''m using.

// rcRect is just a RECT structure.

case WM_CTLCOLORSTATIC:
  SelectObject((HDC) wParam, g_App.GetBckBrush());

  //

  // Set the text background color and background mode.

  SetBkMode((HDC) wParam, TRANSPARENT);
  SetBkColor((HDC) wParam, g_App.GetBkColor());

  //

  // Set the text foreground color.

  SetTextColor((HDC) wParam, g_App.GetTextColor());

  //

  // Return the control background brush.

  return (long) g_App.GetBckBrush();
  break;

Just to clarify what made the difference - you needed to set the background mode to TRANSPARENT so that anything in the background doesn''t get overdrawn except where the actual text is.
