Non-Subspace Related Coding - Need some Win32 help Mr Ekted - Thu Feb 09, 2006 6:01 pm Post subject: Need some Win32 help
I'm looking for some help from any serious win32 developers (if there are any here). The problem deals with using a subclassed edit control, WM_CTLCOLOREDIT, and SetBkMode(dc, TRANSPARENT). If you have no idea what I am talking about, then you can't help me.

Wish I could help, sincerely, but I'm as clueless as learjett on this one.
Did you try the win32assembly community forums?

Well, that made sense to me, but I usually come to you for help, so I don't think I'm of any use here.
But you could go ahead and say what's up.

What exactly is the problem?
Mr Ekted - Fri Feb 10, 2006 11:41 am Post subject:
I am trying to create an EDIT control that has a "transparent" background. That is, the window behind it--its parent--has a complex image. I want the text of the edit control to show over this image.
In WM_CTRCOLOREDIT, I set TRANSPARENT, and return NULL_BRUSH.
In WM_ERASEBKGND (subclassed), I blit that portion of the image seen through the control.
The edit control still draws black text on solid white. If I SetBkColor(dc, PURPLE), I see a purple background. So I know it's simply using the current text background color. But it shouldn't be because I have set TRANSPARENT mode.
All the examples I can find online do pretty much exactly this, but no one is doing exactly what I want.
I have since designed my own custom edit control that behaves exactly as I need, except for selection.

Its been a while since Ive had to deal with windows API, but have you tried using SetBkMode(hdc, TRANSPARENT) instead of (or with) SetBkColor?

Ahh.. I didnt assume thats what you were doing.
In any event, it looks like youre doing everything right, I dont see why it wouldnt work at that point. Sorry.
