Hi,

I have created this form -

The treeview on the left is in the first pane. When an item in the treeview is clicked, a new pane is created and attached, and a control is dynamically loaded into the new pane -

'Increment counter
      mlQueryCount = mlQueryCount + 1

'Create new pane and attach it
      Set pneLast = DockingPane1.Panes(DockingPane1.PanesCount)
      Set pneNew = DockingPane1.CreatePane(mlQueryCount, Me.ScaleWidth, Me.ScaleHeight,            DockRightOf, pneLast)
      DockingPane1.AttachPane pneNew, pneLast

'after the first one, we need to instantiate a new control
      If mlQueryCount > 1 Then Load ucQuery(mlQueryCount)

'make the query control visible
      ucQuery(mlQueryCount).Visible = True

'attach the query to the new docking pane
      pneNew.Title = Node.Text
      pneNew.SetHandle ucQuery(mlQueryCount).hwnd

It all works fine except for the blank tab at the left hand end.  I am assuming this tab is there for the first pane (ie. the treeview).  Does anyone have an idea of how I can make the tab invisible (without making the treeview invisible of course)....or, should I be approaching this differently.

Thanks,

Rohan
