Changing Textbox from the cpp file

[JenniferLostTheWar]

What I'm trying to do is change a textbox from the form1 from within the main '.cpp' file.

Basically, I want the text field to change on load. (Later it will be another reason).

Sorry if this is a dumb question. I'm a newbie.

I added the 2 lines in the Header file and changed the textbox from private to public. (guessing this isn't a good idea?)

Then I tried calling the change in the main function of the .cpp file.

Thank you so much for your help

.cpp file
#include "stdafx.h"
#include "Form1.h"

using namespace help;

[STAThreadAttribute]
int main(array<System::String ^> ^args)
{
// Enabling Windows XP visual effects before any controls are created
Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);

// Create the main window and run it
Application::Run(gcnew Form1());

//Added this.
Form1^ myform1 = gcnew Form1();
Form1::myForm1->MyBox->Text = L" ShowME! ";


return 0;
}


form1.h file

#pragma once

BTW. I know I could update it from the form1 file but thats not what I need. :-)
