We are currently evaluating different versions of treeviews for Progress v9.1E, and are having trouble with the one supplied by Codejock Software.

We are using the currently latest trial version 13.0.0 from the website as a test.

I have created a new container and added the Treeview from the OCX, but when I try to "Add" a new node I receive the following error:

Invalid component-handle referenced while processing method/statement: Add.

p-create-treeview W:\p41532_Untitled.ab (5884)

The line of code in question is:

vha-node = chCtrlFrame:Nodes:Add("", "", "", "Sales", "").

Is there something I need to do before this, as the handle to "Nodes" is invalid and hence the error!

Thanks in advance,
