Huh?  listbox?  dir function?  What are you talking about?

TheSlayer, standard C++ provides no features that support this type of thing.  It must be done using OS-specific functions and features, not standard C++ functions.  So before anyone can answer this question we would have to know what OS you are using.

Sorry folks, this is what happens when i do stuff in a hurry.
I'm using Win 98, Visual C++ 6\MFC.  I want to get a list of the files contained in a folder, then open and modify those files. I can handle the opening and modifying bits easily, but i don't know the file names, whick is why i need the list of names

For windows use the FindFirstFile() and FindNextFile() (or FindFirstFileEx() and FindNextFileEx(). functions.  I think I have an example....

This is from a different question...

*******************

You can use the windows API functions FindFirstFile() and FindNextFile().

FindFirstFile() will find the first file in a directory that matches the search string (if there is one) and will fill in a WIN32_FIND_DATA structure with information about the file found.  It will also return a handle to information that windows needs to record so that it can find additional files.   You can then call FindNextFile() to find then next file that matches the search string.  You pass the handle returned from FindFirstFile() to FindNextFile() so it knows what to look for and it will fill in another  WIN32_FIND_DATA structure for the file found.  You then continue calling FindNextFile() until no more files are found.  You can then close the find handle using FindClose().

An example might be

   BOOL  Done;                     // Done searching for files?
   HANDLE  FndHnd = NULL;   // Handle to find data.
   WIN32_FIND_DATA FindDat;  // Info on file found.

   FndHnd = FindFirstFile("C:\\*.txt", &FindDat);
   Done = (FndHnd == NULL);       // Indicate we are done if nothing was found.

   while (!Done)
   {
      cout <<  FindDat.cFileName << endl; // Print name of file found.
      Done = !FindNextFile(FndHnd, &FindDat);
   }
   if (FndHnd)            // If there was anything found, then
      FindClose(FndHnd); // Close the find handle
