Thread: 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; 
}
