Windows Forms -> wo wird nicht event-gebundener quelltext implementiert

Hallo ich habe einen Socket-Chat geschrieben und eine GUI oberfläche mit Windows Forms gebaut.

nun habe ich da ein kleines Problem und zwar muss ich die Methode, die zum lesen des Datenstroms notwendig ist, ständig laufen lassen, bis etwas in ein Textfeld eingegebn wird. nur wo implementiere ich diesen Quelltext?

Hier mal mein Code:

#pragma once
#include <ctime>

namespace Chat {

	using namespace System;
	using namespace System::ComponentModel;
	using namespace System::Collections;
	using namespace System::Windows::Forms;

	public ref class Form1 : public System::Windows::Forms::Form
	{
	public:
		Form1(void)
		{
			InitializeComponent();

			//
			//TODO: Konstruktorcode hier hinzufügen.
			//

			text="";
			IP="";
			Port="";
			Cnct=false;

		}

	protected:
		/// <summary>
		/// Verwendete Ressourcen bereinigen.
		/// </summary>
		~Form1()
		{
			if (components)
			{
				delete components;
			}

Moin, moin

als erstes würde ich Dir empfehlen den Code zu trennen, dass heißt, lager Deinen Code in die CPP aus. Den Code vom Designer belässt Du in der Header.

Form1.h

#pragma once

			this->ResumeLayout(false);

		}
#pragma endregion
private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e);
	};
}

Form1.cpp

// Test.cpp: Hauptprojektdatei.

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

using namespace Test;

[STAThreadAttribute]
int main(array<System::String ^> ^args)
{
	// Aktivieren visueller Effekte von Windows XP, bevor Steuerelemente erstellt werden
	Application::EnableVisualStyles();
	Application::SetCompatibleTextRenderingDefault(false); 

	// Hauptfenster erstellen und ausführen
	Application::Run(gcnew Form1());
	return 0;
}

System::Void Form1::button1_Click(System::Object^  sender, System::EventArgs^  e)
	{

	}

Hier noch mal einen Link dazu: http://www.rb-softarticle.com/Code%20trennen.aspx

Und den Code Deiner Methode packst Du auch in die CPP, musst sie aber zuvor in der Header vereinbaren.
