Is Form2 created by Form1 or vice versa?

If Form1 creates Form2 then you can simply pass your variables to Form2 in the constructor or via Access functions (Get/Set).

If Form1 is created by Form2 you need to use Get functions to pull the values out.

I'll post example code when I get home from work if you need it.

Code:

void Form1::Foo()
{
    // Pass just the data to Form2
    Form2 form2 = new Form2(A(), B(), C());

    // ...
}

or

Code:

Code:

void Form1::Foo()
{
    // Reduce coupling between the two objects by just passing a small/specific 
    // interface to Form2  i.e. don't pass the entire Form.
    Form2 form2 = new Form2((ISmallSpecificInterface)this);

    // ...
}

public interface ISmallSpecificInterface
{
    string A { get;  set; }
}

Or you can create a public property in form1 so call the property from from2.

//In form1

private String _var1;

public String Var1
{
get { return _var1; }
}

//in form2.

private String _var1from1;
_var1from1=form1.Var1();
