problem with MessageBox
-
Hola! I´m making a small Windows Forms App. using VC++.net 2003. Adding a "MessageBox" in the self generated code (the Form1.h - file) works fine, until I add my own header file to the project and include this new header file at the top of the "Form1.h" -file. I get the error message:
error C2653:"MessageBoxA" is not a class or a namespace name.Why this "MessageBoxA"? What could be wrong? thanks doneirik -

MessageBox()function, or are you callingMessageBox()? If the latter, why do this in a .H file?

I´m callin MessageBox : MessageBox::Show("string"); I´m doing it in the self generated code simply because double-clicking e.g. an Button in the design mode, the method that handles this is placed in the Form1.h file automatically. Don´t really need to have it there. Just trying to learn the basics now... doneirik

What could be wrong? thanks doneirikMessageBoxA is the ANSI version of MessageBox (MessageBox is actually a macro that expands to MessageBoxA in ANSI builds and MessageBoxW in UNICODE builds). Apparently the compiler can't see the definition of MessageBoxA at the point of error. Perhaps you didn't include the correct header files in the correct order, or you may have unmatched #ifdef/#endif statements. Since it happens when you include your own header file I'd look in that for unmatched statements. Disclaimer: I have never worked in VC++.net 2003, but the above applies to VC++ 6.0. Cheers Steen.
