Dear net, I hope this hasn't been asked too many times already (i've been reading this group for a month or so...) How does one change the color of text entered and displayed in a dialog box edit control? I've tried the following (which failed as predicted by the SDK manuals) hDC = GetDC(GetDlgItem(hDlg, controlid)); SetTextColor(hDC, RGB(blah, blah, blah)); ReleaseDC(hDC, blah blah); SetTextColor() is apparently intended for TextOut() type operations. I'm trying to show text in RED for a money field that has gone negative (whippeeee). Please email and i'll post the answer if anyone gives a hoot. Thanks for your time, Thomas thomas@hpssl40.mayfield.hp.com

If the control were registered with one of the other DC attributes your fix would work (the text color would not be nuked--see the discussion of DC attributes in Reference--Volume 2--wndclass). However, you can use the WM_CTLCOLOR message. This is sent just before the control paints itself. Just call SetTextColor() as above except use the DC supplied with the message. cheers - Paul Bonneau.
