how to detect if a file has been already created?

[Utumn0]

I've got a path, say c:\mypath\myfile.txt . I 'd like to find out if myfile.txt already exists in that location. How to do that?

[Philip Nicoletti]

CString fname("test.txt");

int exist = GetFileAttributes(fname);

if (exist == -1)
{
MessageBox(fname,"file does not exist",MB_ICONEXCLAMATION);
}
else
{
MessageBox(fname,"file exists",MB_ICONEXCLAMATION);
}





or another method :

CStdioFile myFile;
CString sFileName = "c:\\test.txt";
CFileStatus stat;
if( !myFile.GetStatus(sFileName, stat))
{
MessageBox("file does not exists");
}

use _access(FileName,0)

Rating isn't important...But gurus respect it and keep high

And the REAL "C++" (question was posted under "C++" category =) solution:


#include <fstream>
using std::ifstream;

ifstream file("C:\\path\\filename.ext");
if (file)
{
//file exists
}
else
{
//file not exists
}
