Hi!

I'm declaring in my.h several classes and their methods, which operate
on elements in Form1, so I have there also Form1.h included, then I
include my.h to the Form1.cpp and all works.. I know it's a little bit
lame :)

Now the PROBLEM - I've created Form3 and I want to create in it's .h
file (in public section) pointer to an object of class declared in my.h
and a method which takes as an argument pointer to another class also
declared in my.h

I get "type name expected" error when I don't include my.h to form3.h,
but when I include it I get lots of errors like "Body has already been
declared for function XYZ" or "multiple declaration of XYZ"

Plz help!!
Thx a lot 4 any answer!

OK - Maybe I'm lame but I've found the solution by myself :)

The answer is preporcessor

I had to add:
#ifndef _my_h
#define _my_h
on the beginning

and #endif on the end of my.h file - et voila - it works! Smile
