The easiest way is to send the value from one dialog to another is to use PostMessage().

One way to do it is to have your project2 constructor take a variable of type TextBox. When you instantiate project2 from project1, pass in the textbox from project1. If you're launching them the other way around change the constructor in project1 to receive the TextBox.

"Form1.h"

#include "Form2.h"
...
...
...
...
private: Form2 ^ form2;
private: System::Windows::Forms::TextBox^ tbForm1;

...
...
...
private: System::Void Form1_Load(System::Object^  sender, System::EventArgs^  e) {
      form2 = gcnew Form2(tbForm1);
      form2->Show();
}

This assumes you'll show form2 when form1 loads, but this is just an example.

The other alternative is to make the TextBox a public member and accessing it in the other class by using project1.membervariable . If that's the route you go make sure your headers are all included in the proper place.
