   So if we have a button on the form called Button1 and the intent of 
this action is to execute an SQL and assign the result to the property 
'RecordSet', that is where the compiler presents the error. It appears 
that the compiler isn't aware of the Property.

Private Sub Button1_Click()
    'Compiler gives an 'unknown identifier' error on the next line.
    RecordSet = DatabaseConnection.Exec("Select * FROM MyTable")
END
