[urgent newbie] input streams problem with .NET

I'm now doing a project, and what I need to do is firstly read a txt file using i/o stream. I've include the lib and since I need to do it in the .NET form (header) and I want to make it such that when I click the button, it will do the file read-in.
But I cannot add file declaration such things into the header, as there's no main func there. What should I do? Coz I wanna relate the file read-in to the button.
Million thanks!!

 

Can you frame your question again. I mean I could not get what you are asking? Are you looking for button click handler to be added or what?

 

I have a form called form1.h, and respectively form1.cpp. I have the following code:

Code:

#include "stdafx.h"
#include "Form1.h"
#include <windows.h>
#include <iostream>
#include <fstream>

using namespace fyp1;

int APIENTRY _tWinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPTSTR    lpCmdLine,
                     int       nCmdShow)
{
	System::Threading::Thread::CurrentThread->ApartmentState = System::Threading::ApartmentState::STA;

	ifstream iFile("test.txt");


	Application::Run(new Form1());
	return 0;
}

I wanna add ifstream into above so that I can read-in a file, then pass the parameter into Form1(). But how can I do that? (ignore the button problem, i don't need it now)The above code cannot be compiled.
Thanks again.
