Getting files under a directory

[smashthewindow]

Hi,

 

This isn't directly related to Leadwerks but I guess someone can help me out here.

I'm looking for a function that returns files under a directory on Windows. (It doesn't have to be cross-platform.)

 

So for example, an ideal example would be something like:

 

vector<string> get_files_in_dir( string directory );

 

I'm fine with Win32 API functions but I'm trying to avoid using boost.

Can anyone help me out here?

HANDLE hFind;

WIN32_FIND_DATA data;

 

hFind = FindFirstFile("c:\\*.*", &data);

if (hFind != INVALID_HANDLE_VALUE) {

do {

printf("%s\n", data.cFileName);

} while (FindNextFile(hFind, &data));

FindClose(hFind);

}

 

Found from http://stackoverflow...-directory-in-c

typedef std::vector<std::string> StringArray;

StringArray ListFiles( const std::string folder, const std::string& pattern )
{
   std::string root = folder;
   if( root[root.length()-1] != '\\' &&
       root[root.length()-1] != '/' )
   root += '/';
   root += pattern;
   StringArray v;

   WIN32_FIND_DATA fd;
   HANDLE h = FindFirstFile( root.c_str(), &fd);
   if( h == INVALID_HANDLE_VALUE )
       return v;
   if( fd.dwFileAttributes != FILE_ATTRIBUTE_DIRECTORY )
       v.push_back(fd.cFileName);

   while ( FindNextFile(h, &fd) )
       if( fd.dwFileAttributes != FILE_ATTRIBUTE_DIRECTORY )
           v.push_back(fd.cFileName);
   FindClose( h );
   return v;
}

StringArray ListSubfolders( const std::string folder )
{
   StringArray v;

   std::string root = folder;
   if( root[root.length()-1] != '\\' &&
   root[root.length()-1] != '/' )
   root += '/';
   root += "*";

   WIN32_FIND_DATA fd;
   HANDLE h = FindFirstFile( root.c_str(), &fd);
   if( h == INVALID_HANDLE_VALUE )
       return v;
   if( fd.dwFileAttributes == FILE_ATTRIBUTE_DIRECTORY &&
       strcmp( fd.cFileName, "." ) &&
       strcmp( fd.cFileName, ".." ) )
   {
       v.push_back(fd.cFileName);
   }
   while ( FindNextFile(h, &fd) )
   {
       if( fd.dwFileAttributes == FILE_ATTRIBUTE_DIRECTORY &&
           strcmp( fd.cFileName, "." ) &&
           strcmp( fd.cFileName, ".." ) )
       {
             v.push_back(fd.cFileName);
       }
   }
   FindClose( h );
   return v;
}

Both looks good, thanks Rick & Roland.

Or there is this taken from a little util I wrote:

 

void loadOutputFileDirectoryFileNames(void)
{
DIR *dp;
struct dirent *dirp;
fileListData* pFileListDataItem;
std::string fullFileName;
std::string fileName;
std::string fileExt;
if((dp = opendir(appData.currentOutputDirectory.c_str())) == NULL) {
 MessageBoxA(0,"An error occured trying to open the output directory","ERROR",0); // errno
 return;
}
clearDirectoryFileList();

while ((dirp = readdir(dp)) != NULL) {

fullFileName = dirp->d_name;
// Check the file extension
if(getFileNameComponents(fullFileName, fileName, fileExt))
{
for(int i = 0; i < vecExtList.size(); i++)
{
if(fileExt == vecExtList[i])
{
 pFileListDataItem = new fileListData;
 pFileListDataItem->currentFileName = fileName;
 pFileListDataItem->currentFileExt = fileExt;
 pFileListDataItem->updated= false;
 vecFileList.push_back(pFileListDataItem);
 break;
}
}
}
}
closedir(dp);
return;
}

 

 

requires dirent.h form the C POSIX library

 

It's doing more than you require but its another alternative.

 

Sorry for the poor tabs ... this container always seens to screw them up. How come your's is perfect Roland

[Roland]

My tabs are also screwed up. But as I can't stand seeing that I go in and edit afterwards.

ahha ... that explains it ... cheers Roland
