Hello friends! I'm trying to use directory_iterator but when I try to list recursivelly an entire drive or a big directory I get an unhandled exception. I'm trying to figure out if I did something wrong but the code is very similar to the example on the boost web page. Here is the code: //------------------------------------------------------------------- VOID CFileSearch::InternalSearch( path RootDir ) { directory_iterator EndDirItr; for ( directory_iterator DirItr( RootDir ); DirItr != EndDirItr; ++DirItr ) { if ( is_regular( DirItr->status() ) ) { _tprintf( "FILE: %s\n", DirItr->path().string().c_str() ); } else if ( is_directory( DirItr->status() ) ) { _tprintf( "DIR : %s\n", DirItr->path().string().c_str() ); InternalSearch( DirItr->path() ); } } } //------------------------------------------------------------------- VOID CFileSearch::Search( string RootDir ) { path TempRootDir = system_complete( path( RootDir, native ) ); if ( exists( TempRootDir ) == true ) { InternalSearch( TempRootDir ); } } //------------------------------------------------------------------- CFileSearch FileSearch; FileSearch.Search( "c:\\" ); Is there something wrong in the above code? Thank you in advance. Silvio.
