SYMPTOMS

When you attempt to set an ActiveX Data Objects (ADO) Data Control's Recordset object to a previously dimensioned ADO Recordset the following error is returned:

Run-time error '3704':

The operation requested by the application is not allowed if the object is closed.

CAUSE

This error occurs when the recordset has not been opened yet.

RESOLUTION

The user may either open the recordset prior to assigning it to the ADO Data Control (ADODC), or use the ADODC to create the recordset.

STATUS

This behavior is by design.

   End Sub
