Re: DoDataExchange woes

Hello! I have done very little MFC programming since last summer but now
I'm back again. One of the things I learned about late during my last MFC
session was DoDataExchange. Now I have a few old mfc projects which are
currently using GetDlgItem() and I want to "fix" them. However, fixing
them turned out to be much more difficult than I anticipated...

Last time I was using MSVC++ 2005 sp1 but now I'm using MSVC++ 2008, so my
old projects are in 2005:s format. I started by converting my only project
that was using DoDataExchange to MSVC++ 2008, the program compiles and
runs fine. I didn't have to modify any code or my resource files.

Then I converted a project that's using GetDlgItem() and the problem
here's that in the resource editor the option "Add variable..." when I
right click a control placed on the dialog is grayed out. I can only
select "Add class..." (which is for the dialog itself, right?).
I found that if I remove my already written dialog class (I #if 0:ed it
out) and add a class to the dialog, then "Add variable" gets enabled.
Woohoo, I solved it there I thought at first, but it didn't last long
because as soon as I had modified the generated code to contain the actual
logic it was supposed to contain, "Add variable..." was grayed out again.

So I checked my converted project that was already using DoDataExchange,
that actually works but I see the same behavior in the resource editor,
"Add variable..." is grayed out. Where's the information stored that
dynamic data exchange should be used anyway?

Sigh, long post, hope you made it this far...guess my question is how do
I, in MSVC++ 2008, convert existing projects from using GetDlgItem() to
using dynamic data exchange? This is driving me crazy, spent more than
three hours on it already.

Hope you could make sense of this post, if not, let me know and I will
clarify. I can even upload screenshots to my website if needed. As I said
in the beginning, I haven't used MFC for some time and I feel rusty.
