it's not showing because ctl is declared as Control (general).
since Not all Controls have same Properties, therefore it does not show.
but if you are sure of the correct Type of the control, then you can declare it as such
and its member will show, example
Dim ctl As Control 'general type
Dim tbx As Textbox 'specific type
For Each ctl In Me.Controls
If TypeName(ctl) = "Textbox" Then
Set tbx = ctl
'typing tbx + dot will show you the members (properties)
End If
Next
