Yes I'm posting another noob question about object it's because I'm really new to that programming ( c++ visual and form). So when I try to execute my program it always say to me : 'Unresolved external 'TForm1::myconst' referanced from 'c:/.../file.obj'. I'm sure it's a little thing that I don't know that must be done or anything.

It sounds like you've declare the variable 'myconst' as extern.
If this is so, then before you use the variable in file.cpp you must also declare it there.
e.g.
In TForm1.h
============
extern int myconst = 10;
In file.h or at the top of file.cpp
====================================
extern int myconst; // Links to one above
In file.cpp
============
int a = myconst; // Should be ok.
