** VC++ 4.0/MFC 4.0/Win95/Novice **
Well the response I got was to not change the MFC. Understood.
Now since I am not a VC++ programmer, but more on the VB or PowerBuilder =
level, could you give me some simple instructure on how to change the =
color of a, normally black, 2-d text box, to make the border dark grey. =
You needn't supply code, since I will pass these instructions over to =
people who do know VC++.
I would also like to MIX 2D and 3D controls! I have been told this is =
VERY difficult. Could you let me know of how to do this? I really need =
all 3D controls except anything I would be putting on a white background =
(excluding commandbuttons). I would need to make controls like =
TextBoxes and ListBoxes (dropdown control would be 3-D as usual).
Please let me know if this is possible, and maybe if you could give me a =
20 word or less explanation of Owner-Draw. I don't need anything too =
techinical, but an understanding.
Thanks for your help, I greatly appreciate it!

Powerbuilder certainly doesn't have the capability to do what you want. VB
doesn't either, I don't think. These things are the the kind of details that
those environments sweep away to make sure you can get more work done with
less fuss.

It isn't the kind of thing that can be described in twenty words or less.
Here's as close as I could come:
"Look up WM_CTLCOLOR and learn how to use it. Look up CWnd::SubClassWindow()
and learn how to use it. Learn what the /WINDOWS:4.0 option in the Linker
means. Read up on dialog templates and their format. Read up on
CreateDialogIndirect()."
That's barely complete but still way over twenty words.
Again: doing what you're doing is not trivial for the developer and quite
undstandard for the user--you really need to carefully consider why you wanna
do it.

Ah, isn't this breaking the rules? J/K of course.
[Moderator's note: Yes, I'm afraid it is, and I've mentioned it
to Brandon.]

You need to use the native CTL3D APIs to achieve this. In particular,
look at the APIs Ctl3dSubclassCtlEx() and Ctl3dCtlColorEx(). You'll also
need to find some documentation on the complete CTL3D API, since I didn't
seem to find much in MSDEV's online help about it.

Use that standard edit control in your dialog only make the control
borderless . Then subclass the CEdit control class and include a
OnDraw(...) memeber function that determines the edges of the control and
uses a grey pen to paint draw along the 4 edges. Petzold has some good GDI
examples, you
could also get a book called Visual C++ Power Tools that has excellent
examples of controls etc.
