Yes, you need to include the file in each form. I suspect a typo error in your program, since you say you already included the file.

Basically, if you know C/C++, it's easy to know when and where to include a header file, because it's like in C #define in .h file. IE: the defined constant is in fact only a macrosubstitution at compile time.

And avoid having many constants in header files since this is extremly heavy for the compiler and it slows down seriously the compile time.

>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.
