This is not working. It says "Form 22 : There is no such file or directory".

Can someone please help ?

If you have a file "Form22.h" then you should #include "Form22.h"
tejas1995 (58)
I have done that, to which it gives the following errors


Form22 : undeclared identifier
Left of '->ShowDialog' must point to class/struct/union/generic type
shacktar (1187)
Form22->ShowDialog();

That means that "Form22" is not declared (i.e. you haven't made a variable called "Form22").
tejas1995 (58)
Then what is the code to show the form ?
shacktar (1187)
Can we see the code in "Form22.h"?

I assume you've defined a class in "Form22.h". Without seeing the code, I'm going to just call it Form22_Class. Normally I would assume it was Form22 but that is getting an undeclared identifier error (maybe Form22 is in a namespace?).

Anyway, it should be as simple as creating a Form22_Class member in Form1

     private:
          Form22_Class form22Instance;
     
     ...
};


and simply calling form22Instance.ShowDialog();

I havent put any code in Form22.h
