Honestly, the best way is to not do forms programming in C++.  Use C# to
build a user interface for your core functionality implemented in C++/CLI.

If you really want to rename a form, you need to rename all of the bits
individually - the .h file, the .cpp file (if there is one), the class
declaration, any typedefs or other uses of the class name, and I think there
are 1 or two designer-generated literal strings containing the form name as
well.

It's a PITA.

Since you are asking in a managed VC++ newsgroup, I'll assume you are
programming using managed code:

Form form  ;

form.Text = "form title" ;
