Forms:Detect if Form is Loaded as a Subform

Derived from the Access 97 Developer's Handbook, (p503), there is a function which allows you to detect if the current form is loaded as a subform--very helpful, since you may want to, say, hide certain controls if the form is currently loaded as a subform.

Here is the function:

Function IsSubForm(frm as Form) as Boolean
   'Is the form referenced in the parameter currently loaded
   'as a subform? Check its Parent property to find out.

   Dim strName as String
   On Error Resume Next
   strname = frm.Parent.Name
   IsSubForm = (Err = 0)
   On Error GoTo 0
End Function

The code that would execute to perform the check:

If IsSubform(Me) Then
   'It's a subform
Else
   'It is NOT a subform
End If
