Re: CListCtrl and file system

Here are some things you could consider:

1. You could detect the device change if your program is running and then
just scan through the folder tree using CFileFind and scan each of the
folders.
2. You could build an "object" for each folder/file that you find including
a pointer to the folder, the human readable name, and anything else you'd
need to display it.
3. You could store the objects in an object list.
4. Then you could scan the final list and add the descriptions to a drop
down combo or list box so the user could display the one they want.
5. When the user selects an item you already have a path to the file(s) for
that item in our coorelating object (in the list).

Here is a code snippet I wrote for creating folders in a tree. Perhaps it
will help you to traverse the tree as well. I would do this recursively (as
you come to a sub folder work your way down then eventually you will work
your way back out).

//
// Create all folders needed to get to a path if they are not already there.
//
void CreateAllDirectories(CString strDir)
{
     if(strDir.IsEmpty())
      return;
    // remove ending / if exists
    RemoveSlash(strDir);

     // base case . . .if directory exists
     if(FileExists(strDir))
          return;

     // recursive call, one fewer directories
     int nFound = strDir.ReverseFind(_T('\\'));
         CreateAllDirectories(strDir.Left(nFound));

     // actual work
     CreateDirectory(strDir,NULL);
}

Your loop would be using the results of the CFileFind and you'd "recurse"
when you find a folder rather than a file to work your way down.
