I have been around the block on this one and have discovered (after numerous hours and discussions with Doug Hennig!) that the only way to solve all the registration problems is to add the TreeView control to the form dynamically at runtime.

This is a royal pain and I wouldn't do it unless it was absolutely necessary...which it seems to be.

Here's what you need to do:

In a .prg file, define the TreeView class as shown in the following example:

DEFINE CLASS MyTreeView AS OleControl
OleClass = 'COMCTL.TreeCtrl'



ENDDEFINE
