Thread: Folder listing

Hi using MFC how could I go about getting the listing of folder on a certain drive, say I get the user to choose the drive from a drop down box, how can i then look at that drives contents, but specifically folders.

Thanks.

My xtree in this FAQ perhaps?

Thanks, that will probably help, it's gonna take me a while to understand it properly though.

Another possibility is to use a CListBox control and fill it up with file/directory names with the DlgDirList api. Something like:

Code:

//get length of path to windows dir
int len=GetEnvironmentVariable("windir",0,0);
if (len)
  {
  char *path=new char[len+1];
      
  GetEnvironmentVariable("windir",path,len);
  //fill listbox with file/directory names
  int ret=::DlgDirList(*this,path,IDC_LIST1, IDC_STATIC_DIR,
                       DDL_DIRECTORY|DDL_EXCLUSIVE|DDL_SYSTEM);
      
  delete[] path;
  }
else
  {
  //error
  }

where this is the CWnd parent object of the CListBox control, IDC_LIST1 is the listbox id and IDC_STATIC_DIR the id of a 'buddy' static control. You might have to fiddle around a bit to get a format to suit (eg. convert short to long filenames).

I don't use mfc much so there may be a more mfc friendly way of implementing this approach that others may be able to suggest.
