You can call a procedure in a module associated with a subform or subreport in one of two ways. If the form containing the subform is open in Form view, you can refer to the procedure as a method on the subform. The following example shows how to call the procedure GetProductID in the Orders Subform, which is bound to a subform control on the Orders form:
In the Orders Subform class module enter:
Public Function GetProductID() As Variant
' Return current productID.
GetProductID = ProductID
End Function
Forms!Orders![Orders Subform].Form.GetProductID
You can also create a new instance of the form that is being used as a subform, even if neither the main form nor the subform is open, and call the procedure. This will work for any form, whether or not it is being used as a subform. The following example shows how to create an instance of the Orders Subform and call the GetProductID procedure:
Dim frm As New [Form_Orders Subform]
frm.GetProductID
Note
When you create a new instance of a form with a name consisting of more than one word, enclose the class name of the form in brackets, as shown in the preceding example.
