Saving int to file as text?

I'm trying to save an int to a file so that it can be read in notepad. Currently it is going to save the score to the file, and I'm probably going to have it so it saves a high score list or something later.
The problem is that I think it is saving in binary, because when I open it in notepad all I get is the "unsupported character symbol" (looks like a rectangle). Here's what I've got:

Code:

int score=0;//this is added up through the game
DWORD dw=0;
HANDLE hFile=0;
hFile=CreateFile("score.txt" ,GENERIC_WRITE,0,0,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,0);
WriteFile(hFile,(void *)&score,sizeof(int),&dw,0);
CloseHandle(hFile);

Thanks!

First, be sure to include stdio.h:

FILE *file = fopen("myfile.txt", "wb"); // Open file
int integer = 100; // Sample integer
fprintf("%d", integer); // Write to file
fclose(file);

That should work =).

I've never used CreateFile/WriteFile myself, but according to the helpfiles they can only write binary data, meaning you have to convert your integer value to a string then write each letter in that.

Or, simply use a C++ filestream and your problems are solved automatically:

Code:

int HighScore;
ofstream WriteFile;

WriteFile.open("MyFile.txt", ios::out | ios::trunc);
if(!WriteFile.fail())
{
   WriteFile << "The highscore is: " << HighScore << endl;
   WriteFile.close();
}

This is a C++ forum, not C

Or if you want, you can use a string stream:

Code:

#include <strstream>

//Later in code...
ostringstream oss;  //creates a string stream for output

oss <<number;  //outputs int to the string stream
oss.str()   //returns the char* representation of the string stream
                //which you can use to output to file

But simply using the << operator of an ofstream object would probably be the easiest way

Sure, there're better ways, but it's still C++.

Thank you for the suggestions. I think I'm going to try Magos's technique first.

Magos, have you started on OpenGL? (I know you were doing DX stuff) Just curious.

Nope, no OpenGL. I'm working on a game in DX. Progress is slow though...

Just curious, how did you decide to use directX versus openGL?

I was in my early gamecreator wannabe stages (like most programmers ) and simply decided to use DX. Didn't know much about them, so i guess it was just random.
