I have an int s and want to convert this to string s.
How?

Thanks

You can't convert an integer to string the only thing you can do is to "insert" it in.

CString str;
int s;
str.Format("%d", s);

yes it is possible to convert an integer to a string.
you can do it by using this fonction:
char *_itoa( int value, char *string, int radix )

an example:

#include<stdlib.h>
#include<iostream.h>
void main()
{
char buffer[20];
int number = 7254;
cout<<&quot;buffer = &quot;<<_itoa( number, buffer, 10 );
}
// notice that the last parameter of that fonction neads to be equal to 10 if you want your number to be stored as a decimal value.By choosing 2 as the last parameter would convert your number to binary etc.

Impress your friends and colleagues.

If you want to use a fancy pure C++ construct, you can do this:

#include <iostream>
#include <sstream>
#include <string>

int intFromString(const std::string& s)
{
std::istringstream i(s);
int x;
if (i >> x)
return x;
// error handling goes here...
return 0;
}

You can write a custom handler for all data types and then you will never face the problem again.

Ooops I gave you string to int, which isn't what you wanted. Of course the solution is similar, again using the fancy pure C++ constructs:

#include <iostream>
#include <sstream>
#include <string>

std::string convertToString(int x)
{
std:stringstream o;
if (o << x)
return o.str();

// error handling
return &quot;conversion error&quot;;
}
