Hi,

A few threads ago I posted some notes and in another some code. This is
basically what you need

WIN32_FIND_DATA FindFileData;
  HANDLE hFind;
  string Wild = Dirname;

  if( !Wild.empty() )
  {
   if( *Wild.rbegin() != '\\' ) Wild += '\\';

  }
  string Dir = Wild;
  Wild += "*.*";

  hFind = FindFirstFileEx( Wild.c_str(), FindExInfoStandard, &FindFileData,
   FindExSearchNameMatch, NULL, 0 );

  if (hFind == INVALID_HANDLE_VALUE)
  {

   stringstream Error;
   Error << "Invalid File Handle. GetLastError reports " << GetLastError ()
<< endl;

// NOTE if errorcode is 2 it isn't really an error ('no such file or
directory')

   throw CInfoException( Error.str() );
  }
  else
  {
  do
  {
//NOTE: Filename = FindFileData.cFileName,
  }
  while( FindNextFile( hFind, &FindFileData ) );

     FindClose(hFind);

Hello NG,

I have written some code which worked fine under c#. But i don?t know,
how this shoud work in c++. I have tryed much things, but i can?t find
out how to use DirectoryInfo and FileInfo under c++.

Thanks for any hints!
Peter

Here is the c# code:

//
---------------------------------------------------------------------
// -- View *.prn Files in Directory
//
---------------------------------------------------------------------
void Btn_aktualisierenClick(object sender, System.EventArgs e)
{
// clear listview
lv_fileliste.Clear();

DirectoryInfo dir = new DirectoryInfo("c:\\");
FileInfo[] fileInfo = dir.GetFiles("*.prn");

// Insert files in listview
foreach ( FileInfo fi in fileInfo )
{
lv_fileliste.Items.Add(fi.Name.ToString(),0);
}
}
