Error when moving treeview to a tabcontrol

[Peter]

I'm trying to move a treeview control to a tab page.
Basic4PPC responds with the error message : Unable to cast object of type 'Dbasic.Other.SwrapObject' to type 'System.Windows.Forms.Control'

Am I doing something wrong?

Sub App_Start

    Form1.Show
    sip(true)
    AddLabel (form1,"Label2", 5, 5, 60, 20, "Option:")
    AddTextBox (Form1,"TextBox1",40,20,100,25,"")
    tbc.New1 ("Form1", -5,0, 245, 280)
        tbc.AddTabPage("Aantallen")    
          tbc.AddTabPage("Hoorspel")
           tbc.AddTabPage("Personen")
        tbc.AddTabPage("Zoeken")
        tbc.AddTabPage("Lijsten")
        tbc.AddTabPage("X")
        tbc.AddTabPage("Z")
        tbc.AddTabPage("Configuratie")
        'tbc.AddControl("label1",0,20,20)
        tbc.AddControl("label2",0,20,60)        
    Con.New1
    Reader.New1
    tv.New1("Form1", 5, 5, Form1.Width - 10, Form1.Height - 10)    
    Node.New1
    <font color="Red">tbc.AddControl("tv",1,20,20)</font>
    Cmd.New1("",con.Value)
    Con.Open("Data Source = " & AppPath & "\DNH4ppc.sl3")

End Sub

The right syntax is:
tbc.AddControl(tv.Control,1,20,20)

This is different than regular controls because TreeView is not a built-in control.

Thank you, Erel, that works.

Could i have found that in one of the help-files?
