? IsControlSelected (Forms!Customers, "CompanyName") 
Function IsControlSelected(frm As Form, _ 
 strControlName As String) As Boolean 
 Dim intI As Integer, ctl As Control 
 If frm.CurrentView <> 0 Then 
 ' Form is not in Design view. 
 Exit Function 
 For intI = 0 To frm.Count - 1 
 Set ctl = frm(intI) 
 If ctl.InSelection = True Then 
 ' Is desired control selected? 
 If UCase(ctl.Name) = UCase(strControlName) Then
