in the automatically-generated Form1.h in MSVC 2010, how could I set the text of a textbox while the program is running?

the Form1.h looks something like this:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

			this->Controls->Add(this->splitContainer1);
			this->Controls->Add(this->label3);
			this->Controls->Add(this->label2);
			this->Controls->Add(this->progressBar1);
			this->Icon = (cli::safe_cast<System::Drawing::Icon^  >(resources->GetObject(L"$this.Icon")));
			this->Name = L"Form1";
			this->Text = L"Prime Calc";
			this->groupBox1->ResumeLayout(false);
			this->splitContainer1->Panel1->ResumeLayout(false);
			this->splitContainer1->Panel1->PerformLayout();
			this->splitContainer1->Panel2->ResumeLayout(false);
			this->splitContainer1->Panel2->PerformLayout();
			(cli::safe_cast<System::ComponentModel::ISupportInitialize^  >(this->splitContainer1))->EndInit();
			this->splitContainer1->ResumeLayout(false);
			this->ResumeLayout(false);
			this->PerformLayout();

		}
#pragma endregion


and this is what I came up with:

// Primes.cpp : main project file.

#include "stdafx.h"
#include "Form1.h"
#include "math.h"

using namespace Primes;
using namespace std;


void print(char text)
{
	//right here I want this to change the text of the 'output' box
	//to the string carried by 'text'.  This is my non-working idea
	//based on Form1.h, and since my native programming language is
	//Lua, (more specifically, RBX.Lua) it appears to be perfectly
	//acceptable.
	Form1.output.Text=L"Hello";
}

[STAThreadAttribute]
int main(array<System::String ^> ^args)
{
	Application::EnableVisualStyles();
	Application::SetCompatibleTextRenderingDefault(false);
	Application::Run(gcnew Form1());

	print("hello");//not meant to pass the variable until it's figured out

	return 0;
}
Edit & run on cpp.sh


Who can help?

Does no one know how to do this? It seems like a pretty simple thing to do to me.

It probably is. This is a C++ forum, though. The above code isn't C++.

In Form1.h there should be a line similar to this->output->Text=L""; in InitializeComponent() afaik you cant access the Form object since it is a temporary sent directly to Application::Run.

As you can see, this forum is hardly a good forum for C++/CLI. I don't really know how you guys end up asking questions here.

The best forum for C++/CLI is the MSDN Forums.

Thanks,
I'll show my big bundle of joy over there, and then ask them :)
