Hi, I´m working on my final project to achieve my diplome in electronical engineering. I have written two algoritms in c++ visual and now I have to write the main-file so that I just have to give the directory in which all the pictures on wich the algoritm has to be applied, are. These means that I'm looking for a function, almost like fstream, that counts the number of the pictures that are in the directory, and than I can with a for lus apply the algoritm on all these pictures. I hope this exists in c++, and I hope that some of you can help me, because I'm almost out of time.

It sure sound like what you need are FindFirstFile() and FindNextFile() [or _findfirst and _findnext].

Here's a sample extracted from working code (with lots of extraneous stuff removed)




BOOL             bRC;
WIN32_FIND_DATA  FindData;
HANDLE           FindH;
char             TempStr[256];
char             FromFile[256];
char             ToFile[256];

strcpy(TempStr,NSEDir);
strcat(TempStr,"*.*");
FindH=FindFirstFile(TempStr,&FindData);
if (FindH!=INVALID_HANDLE_VALUE)
   {
   bRC=TRUE;
   while (bRC)
         {
         // Skip directories
         if (!(FindData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY))
            {
            ...stuff
            }
         bRC=FindNextFile(FindH,&FindData);
         }
   FindClose(FindH);
   }
return;
}
