Hi there,
Having posted in the C++ part of the forum I have been directed over to the .NET Base class Library. Below is my original post and my really poor attempt at implementing the advice given. I am really quite struggling to get to grips with this so any help is much appreciated.
"Hi there,
I am currently attempting to enhance an old program to use Windows Forms in C++. From what Ive read it would be preferable to use Visual Basic or C#; however in its current state, combined with my lack of experience in C#/VB this would be a real struggle to attempt at this stage.
Hopefully by outlining an example it will be possible to convey my current issue.
Essentially I have opened a string stream and passed its contents into a std::string. Originally this was to be output in the console screen. By implementing Windows forms in my programme I now wish to create a button that when clicked opens the saveFileDialog allowing me to save this string as a text file.
This is where I curently am at:
//string.h
#include <iostream>
#include <sstream>
class test
{
public:
std::string write();
};
//string.cpp
#include "stdafx.h"
#include "string.h"
std::string test::write()
{
std::ostringstream output;
output << "HELLO" << std::endl;
output << "HELLO AGAIN" << std::endl;
std::string s2 = output.str();
return s2;
}
//Form1.h
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e){
test a;
SaveFileDialog ^ saveFileDialog1 = gcnew SaveFileDialog();
saveFileDialog->Filter = "Text file (*.txt)|*.txt";
saveFileDialog->Title = "Save a text file";
//CODE REQUIRED TO SAVE s2 AS .TXT FILE
saveFileDialog1->ShowDialog();
}
I hope it can be seen that I have a seperate string.ccp and corresponding header file to define the string contents which is a requirement of my programme.
Unless what I have done is flawed in some way I think all I need is a point in the direction as to what code to place in Form1.h as there is very little information around the internet for this sort of thing.
One piece that I did find used fsteam instead of sstrem though im not sure if this would make a significant difference?
Thank you very much in advance for looking at this, your time is much appreciated.

This was my next step but as far as I am aware, Im missing the code for the next step which I really cant figure out:
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e){
test a;
SaveFileDialog ^ saveFileDialog1 = gcnew SaveFileDialog();
saveFileDialog->Filter = "Text file (*.txt)|*.txt";
saveFileDialog->Title = "Save a text file";
saveFileDialog1->ShowDialog();
if (result == System::Windows::Forms::DialogResult::OK)
{
string b = a.write();
///lost
}
}
Once again thank you for all your help/
C++ -- saveFileDialog
