Thread: Pass value from Form3 to Form2

There is one function that I really need to know and understand how to do.
The example is that I have is a form application with 3 Forms.
Form1 is the starting form.

What I need to do now is to pass a value from Form3 to Form2 and
let Form2 Show a message with this "String".

RealExample would be:

Form3:

Code:

String^ PassThisString = "PassThisToForm2";

private: System::Void button4_Click(System::Object^  sender, System::EventArgs^  e) 
{
		 
	//Pass, PassThisString to Form2 ?
                  this->Close(); //After passing, close Form3
}

Now, the PassThisString will be send to Form2 and showed in a ex: MessageBox like:

Code:

MessageBox::Show(PassThisString)

I have been wondering for a long time how you can do this the easiest way but never got a good answer on this.
I have always been working within the form where I know how to call GlobalVariables and button, events.

Thank you in advance
