How do I turn this C++ into a win32 c++ app?

[Sam Granger]

#include <iostream>
#include <fstream>
#include <cstring>

using namespace std;

int main()
{
    string r_place;
    string word;
    
    ifstream f_in("example.txt");//open file to READ
    
    cout<<"Enter word you wish to replace"<<endl;
    cin>>word;
    cin.ignore();
    
    int size = word.length();//find the length of the word
    
    cout<<"Enter word you wish to replace it with"<<endl;
    getline(cin,r_place,'\n');
    
    cin.ignore();
    cout<<"\n\n";
    
    
    string search;
    ofstream f_out("update.txt");//open file to WRITE
    
    while(getline(f_in, search, '\n'))//read in a line
    {
        
       
    string::size_type pos = -1;
    while( ( pos = search.find(word, pos+1) ) != string::npos )
    {
        search.replace(pos,size,r_place);
        //search.erase( (search.begin() + pos), (search.begin() + (pos + size)) );
        //search.insert( pos, r_place );
    }
    f_out << search << endl;//Write to file
        
        
    }
    f_in.close(); //close file (reading)
    f_out.close(); //close file (writing)
    cin.get();
    
    
} 

How do I put this in a application (Borland c++ 6) with forms (win32).

For example I have a tick box and if you tick it, and you click a button it finds a code thats linked to the tickbox in an external file and replaces it with a text (also linked to the tick box).

Well do you know how to create a window yet?

[Sam Granger]

Yes.

[jmd15]

Ok, then you will be able to understand my code, or hopefully. I know I got a bit carried away and went and wrote the whole thing in Win32 for you, but here it is. Attached:

EDIT: Oh yeah, sorry about the comments. I started commenting the code but then I just got carried away and forgot to comment the rest. I hope it's easy enough to figure out though.

[Sam Granger]

Wow Thanks!!! Works like a dream!!!

[Sam Granger]

I'm going to be in prague tomorrow till sunday so I'll only be online again on monday so if I get stuck editting, thats when you'll here me screaming for help. :P

[jmd15]

Glad I could help. I will answer your questions, when you get back. You are going to Prague, as in the capital of the Czech Republic?

Yep, thats the place

Well, I did it with stdio.h functions...

[Sam Granger]

Hmm, How do I open the form view in c++ (borland 6)

[Sam Granger]

Anyone?

[jmd15]

Sorry, I use Dev-C++. I personally dislike Borland products, but that's just me.

[bumfluff]

I use Dev-C++ but I dont like the resource editor, are there any good ones freeware?

MinGW Studio is the only freeware IDE I can think of that has an integrated visual resource editor.

Ahh ok, I'll try that
