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
	tbc.AddControl("tv",1,20,20)
	Cmd.New1("",con.Value)
	Con.Open("Data Source = " & AppPath & "\DNH4ppc.sl3")

End Sub

[Erel]

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?
