Can anybody help me whith a small problem?

I need to create a program that finds .trc files on the disk. I have tried the FindFirstFile() method but I dont seem to get it right. There are som problems whith the headerfiles as well. Plz tell me witch HFiles to include.

Lets say that I get the Find function working. How do I change the name on the file?

Here is my code.

#include <winbase.h>
#include "Control.h"
#include <stdio.h>
#include "stdafx.h"
#include <fstream.h>

void main( void )
{
    WIN32_FIND_DATA trc_File;
    HANDLE hFile;

      if((hFile = FindFirstFile("*.trc", &trc_File)) == NULL )
      {
         printf( "No *.trc files in current directory!\n" );
      }
      else
      {
            /* Find the rest of the .trc files */

      while( FindNextFile ( hFile, &trc_File ) == 0 )
        {
      
        }

       FindClose( hFile );
   }
}

You should #include <windows.h> instead of winbase.h ...

Here is a version of your code that will rename all the "*.trc" files to "*.xxx".

#include <windows.h>
#include <stdio.h>
#include <fstream.h>

#include <string>

void main( void )
{
    WIN32_FIND_DATA trc_File;
    HANDLE hFile;

    hFile = FindFirstFile("*.trc",&trc_File);

    if(hFile == INVALID_HANDLE_VALUE )
    {
       printf( "No *.trc files in current directory!\n" );
    }
    else
    {
    /* Find the rest of the .trc files */

        do
        {
            std::string oldFileName = trc_File.cFileName;
            std::string newFileName = oldFileName;
            int pos = newFileName.find_last_of(".");
            newFileName.replace(pos,4,".xxx");
            ::rename(oldFileName.c_str(), newFileName.c_str());
        } while( FindNextFile ( hFile, &trc_File ));

       FindClose( hFile );
   }
}

Before i give you the points.

Does this code go though the entire drive or just the current directory??

Just the current directory,  I just adapted the structure you gave to make it work.  To get it to search the entire drive you need to make the search filter out directories and then work with them.

Let me know if you want help with this.
