VBA (Visual Basic for Applications) is the code used in Access, so I am not
completely sure of the meaning of your question.
If you mean that your forms were created using Visual Basic (a part of
Microsoft Visual Studio, and a separate product from MS Access), then no,
these are not convertible. The functionality of forms and controls in MS
Access is so different from forms and controls in Visual Basic that any
conversion would do little good, for you would spend almost as much time
tweaking the converted forms and controls to make them truly functional in
MS Access as you would in creating them anew.
