Thread: Edit Controls - Colors - Messages

Hi All,

I need to know whats going on here I am working with edit controls. I have been trying to change the background brush on them, but cant seem to be able to access the background. I have been trying with GetClassLong and SetClassLong. This dont work, but i guess its because i havent registert the edit control and it hasnt got its on WNDCLASSEX set up. Anyway, i have managed by catching the WM_CTLCOLOREDIT and setcolor and background there. But that only works on one line of text at a time. So in the edit window procedure(subclassed), under the WM_PAINT i get the rect in the painstructure and use it in a call to FillRect to set the background color. My question is: If i take the setbk, settext..statements in the WM_CTLCOLOREDIT case and put them just before the FillRect in the subclass rutine, it dosnt work? The way i understand it is that the WM_CTLCOLOREDIT message is sent just before the paint message and would it matter where you had those statements(setbk...setText) e.g. in the WM_CTLCOLOREDIT or WM_PAINT? And is there a easier way to set the background. E.g. in a call to some function the same as GetClassLong etc....

he he, ok, i just found this code after a search on the board. This works perfectly. But whats exactly is happening. I understand the everythig expect the return statement. Is this returning to the Edit controls window procedure. Either the subclassed or default? And how is it setting the background color by returning the stockobjent ( my mind is boggling trying to figure out how this works)

Code:

case WM_CTLCOLOREDIT:{
   if((HWND)lparam == messageHwnd){
      SetTextColor((HDC)wparam, RGB(255,255,255));
      SetBkMode((HDC)wparam, TRANSPARENT);
      return (int)(HBRUSH)GetStockObject(BLACK_BRUSH);
  }	                
						         
  return(0);
}

hehe, ok....dosnt say that here, but then again...got old msnd documentation...

Ta....
