Given tha path, find an exe(given the size) into it

Hi to all :)

I've done a little program that looks for a specific file on the disk.
Once I've found that file (file_to_find.txt) I've done half work, beacuse now I want to look for an *.exe (I dont know the name beacuse it's quite allways renamed by the user, I only know 3 sizes of it that means 3 version of the same exe) that is in the same folder where I found file_to_find.txt (that the user can't rename). I want to look for that *.exe and I want know it's NAME.EXTENSION (or only the name.....I know it's an exe)

The code for the search in C is this one :

Code:

---

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

//Looking for a File by BianConiglio //

int look4aFile (char* strStartPath) 
{
  HANDLE hFileSearch;
  WIN32_FIND_DATA hFileSearchData;

  int lastError = 0;
  char* currentSearchPattern = (char*) malloc( MAX_PATH );
  char* reservedBuffer;

  if (currentSearchPattern)
  {
      if (!strStartPath)
        strStartPath = "C:\\";

      strcpy (currentSearchPattern, strStartPath);
      strcat (currentSearchPattern, "*");

      if ( (hFileSearch = FindFirstFile(currentSearchPattern, &hFileSearchData)) != INVALID_HANDLE_VALUE )
      {
        do {
            if ( strcmp(hFileSearchData.cFileName, ".") && strcmp(hFileSearchData.cFileName, "..") )
            {
              if ( hFileSearchData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY ) {

                  reservedBuffer = (char*) malloc( MAX_PATH+1 );
                  if ( reservedBuffer )
                  {
                    strcpy (reservedBuffer, strStartPath);
                    strcat (reservedBuffer, hFileSearchData.cFileName);
                    strcat (reservedBuffer, "\\");

                    lastError = look4aFile (reservedBuffer);

                    free (reservedBuffer);

                  } else
                    lastError = -1;
       
              } else {
                                     
                  if ( !stricmp(hFileSearchData.cFileName, "file_to_find.txt" ))
                 
                  printf ("I've found a file \"%s\" in the folder \"%s\"\n", hFileSearchData.cFileName, strStartPath);
                   
                }
            }
             
        }
   
          while ( FindNextFile(hFileSearch, &hFileSearchData) );
      } else
        lastError = 1;

      free (currentSearchPattern);
      FindClose (hFileSearch);

  } else
      lastError = -1;

  return lastError;
}


int main()

{

  look4aFile (NULL);
 
  system("PAUSE");   
  return 0;
}

In that "for" I have to add the code for searching the exe (the exe size is standard, i have 3 sizes that i can define in the program)

Code:

---

if ( !stricmp(hFileSearchData.cFileName, "file_to_find.txt" ))
                 
                  printf ("I've found a file \"%s\" in the folder \"%s\"\n", hFileSearchData.cFileName, strStartPath);

---

strStartPath is the path found, I have to search in it an exe with one fo the 3 (defined) size... some help ?

Thanx to everyone

Try this.

Code:

---

int find_exe(char directory[])
/* directory is path in which to look for file */
/* example:  \\dir\\subdir\\                  */
{
  DWORD file_size[3] = {20000, 30000, 40000 };
  HANDLE hFileSearch;
  WIN32_FIND_DATA hFileSearchData;
  int lastError = 0;

  char* currentSearchPattern = malloc( MAX_PATH );
  if (currentSearchPattern)
  {
      strcpy(currentSearchPattern,directory);
      strcat(currentSearchPattern,"*.EXE");

      if ( (hFileSearch = FindFirstFile(currentSearchPattern, &hFileSearchData)) != INVALID_HANDLE_VALUE )
      {
        do {
            if ( strcmp(hFileSearchData.cFileName, ".") && strcmp(hFileSearchData.cFileName, "..") )
            {
              if (hFileSearchData.nFileSizeLow == file_size[0] ||
                  hFileSearchData.nFileSizeLow == file_size[1] ||
                  hFileSearchData.nFileSizeLow == file_size[2])
                  printf("EXE found: %s  size: %ld\n",hFileSearchData.cFileName,
                    hFileSearchData.nFileSizeLow);
            }
             
        } while ( FindNextFile(hFileSearch, &hFileSearchData) );
        FindClose (hFileSearch);
      } else
        lastError = 1;

      free (currentSearchPattern);

  } else
      lastError = -1;
}
