Hi Paul,

>Does anyone know where I can find a class like the Windows Explorer that uses the + and - signs to expand and collapse branches of a tree structure?

The TreeView ActiveX is exactly this.

There are some sample files here if you've never used ActiveX controls:

Under Classes - VCX
File#412
File#599

Under ActiveX in VFP
File#1019
File#1050
File#1086 < --This ones a good sample
File#9617
