ACC: No Err w/ Multiple Dynaset.Close Statements Based on Form

• Microsoft Access versions 1.0, 1.1, 2.0, 7.0, 97

SYMPTOMS

Moderate: Requires basic macro, coding, and interoperability skills.

If you use code to create a recordset that is based on a form, you can use multiple Dynaset.Close statements without generating an error message.

STATUS

This behavior is by design.

MORE INFORMATION

NOTE: The Dynaset property is included in Microsoft Access 2.0, 7.0, and 97 only for compatibility with earlier versions. It is recommended that you use the RecordsetClone property instead. In Microsoft Access 7.0 and 97, there is no Dynaset Object; therefore, you cannot declare a variable as a Dynaset.

Steps to Reproduce Behavior

1. Open the sample database Northwind.mdb (or NWIND.MDB in versions 1.x and 2.0).



2. Open the Customers form in Form view.



3. Create the following new module.
   

   
       In Microsoft Access 7.0 and 97
       ------------------------------
   
         Function MultiClose()
            Dim MyDyna as Recordset
            Set MyDyna=Forms![Customers].Dynaset
            MyDyna.Close
            MyDyna.Close
         End Function
   
       In Microsoft Access versions 1.x and 2.0
       ----------------------------------------
   
         '*******************************************************
         'Declarations section of the module.
         '*******************************************************
   
         Option Explicit
   
         '=======================================================
         ' The following function will create a dynaset based on
         ' the Add Products form in the Northwind database. The
         ' function will then attempt to close the dynaset twice.
         '=======================================================
   
         Function MultiClose()
            Dim MyDyna as Dynaset
            Set MyDyna=Forms![Customers].Dynaset
            MyDyna.Close
            MyDyna.Close
         End Function 




4. On the View menu, click Debug Window (or Immediate Window in versions 1.x and 2.0).



5. Run the code that you created in step 3 by typing "? MultiClose()" (without the quotation marks) in the Debug Window. Note that there are no error messages, even though the code attempts to close the dynaset more than once.
