>I have an include file with some constants. In particular, MSG_ERROR is defined in this include file. I have a form class. In the form class I include that include file. I create a form based on the formclass. Some of the code in the form is "WAIT WINDOW MSG_ERROR". When this code is encountered I get, "Variable 'MSG_ERROR' is not found." I figured I forgot to compile everything. So, I did that. Same error. Perhaps the include file needs to be in the form also? I did that and recompiled everything. Same error. This is rather odd and I'm stymied on what to do next.

Hey Michael,
What a coincidence! I've just ran into this same problem couple of days ago for some weird reason and I couldn't understand why because I also had "included" the header in the form AND the base class. Well, my solution was perhaps more weird. What I did, as almost a last restort was to:
1. Open the form in design mode.
2. Clear the Include statement altogether.
3. Save the form.
4. Reopen the form.
5. Include the same exact header file again.
6. Save the form again.
7. Run the app/form and now no silly error message.
I don't know if this is a bug since I've never ran into this problem before but above is how I've solved it. Try it and I hope it works for you too.
