SSTab as a Container

[infiniter]

I wrote a function that loops through all the controls of a form, so that I could set some of the properties of all those that belong to a certain container.

This is a small version of that function:

Public Sub setControls(ByVal formulary As Form, ByVal prefix As String, text As String)
    prefix = UCase(prefix)
    Dim control As control
    
    For Each control In formulary.Controls
        If InStr(1, UCase(control.Container.Name), prefix) > 0 Then
            If TypeName(control) = "TextBox" Then
                control.text = text
            End If
        End If
    Next
End Sub

When I call the function

Call setControls(Me, "Frame", "Hi")

it sets every textbox text to "Hi" in all containers whose name starts on "Frame". BUT (cause there is a but) in the case of a SSTab control it's different, because I can't change the properties of the members of just ONE specific tab since the container is the SSTab control and not something like SSTab(1).

The thing is: is there any way to know is a control belongs to a specific tab in a SSTab control?
