Hello,
Very new to B4ppc and having some difficulty from a desktop app...

With this code taken from the help file:
B4X:
'Add a TabControl object named tbc.
Sub Globals


End Sub


Sub App_Start
      Form1.Show
      AddButton(Form1,"Button1",0,0,80,40,"Button1")
      AddTextBox (Form1,"TextBox1",40,20,100,25,"")
      tbc.New1 ("Form1", 10,10, 200, 200)
      tbc.AddTabPage("Page1")
      tbc.AddTabPage("Page2")
      tbc.AddTabPage("Page3")
      tbc.AddControl("Button1",0,20,20)
      tbc.AddControl("TextBox1",1,20,30)
End Sub


Sub tbc_SelectionChanged
      msgbox("Selected page: " & tbc.SelectedIndex)
End Sub
I'm getting an error that I don't understand. (Image attached)

Can someone shed some light here or have some working code as a simple example?

Yikes!!! :sign0148:

It always seems to be the most obvious things that I overlook.

....a perfect way to start off around here.

Thanks for the assist.

I continued to have problems but finally figured out what I was doing wrong.

As it turns out, being completely unfamiliar with how everything works in the IDE, I was leaving out the part about actually adding the tab control as an object (named tbc of course). :(

It all works now and I've learned something new in the process. :sign0060:
