setting the top level viewable folder on a TDirectoryListBox
I would like to modify Delphi 7's existing TDirectoryListBox, so that I can set a top level folder.
If I set the top level folder to be c:\games then the user can only browse the folder c:\games and below, but nothing above it or on the same level. Is this possible? I'm looking for the required code to make the modification, or some insight could be shared on what functions to override.
