CTRL-F4 loses highlighting in ActiveX TreeView

[KeithWilliams]

Hi,

I have a form with one control, an ActiveX TreeView (MIcrosoft Treeview Control, Version 6.0). I trap the CTRL-F4 event to prevent the user closing the form. However, this leads to a problem. Whatever node is selected in the treeview, the highlighting is lost. I've established the Selected boolean value is still True for the node, and if I click in the blank space at the bottom of the treeview, it becomes highlighted again. I just want the user to be able to see that it is selected!

I've tried code like the following, among other things:

Private Sub Form_Unload(Cancel As Integer)
    Dim objNode As Object
    
    If boolCtrlF4 Then
        'Trap the attempt to close the form.
        boolCtrlF4 = False
        Cancel = True
        'Try to restore highlighting to the selected node.
        Set objNode = axTreeViewServiceHierarchy.SelectedItem
        objNode.Selected = False
        objNode.Selected = True
    End If
End Sub

However, all to no avail.

Has anyone come across anything similar with the treeview? Any suggestions?

Thanks,
Keith.
