C++ windows form

[mrcervello]

Hello to everyone.
I have a project in visual studio 2010 with some forms.
In the .cpp file of every form I've defined the function in this way:

void name_project::name_form::name_function() {
code..
}

and i've put the prototypes in the .h file of the form

 
void name_function() 

My question is: I want to use a function defined in a form in another form..I tryed with :: with no result..
Can anyone help me?
Thank you!

you need an instance of name_form in order to access the function plus the function has to be public.
