The only integrated VC solution for Access is Microsoft Visual Source Safe, however it is poorly designed and even Microsoft does not allow it to use it;). Some people call this the "Source Destruction System," but I personally know of success cases with its use. As a rule, this can be a good solution for small and medium-sized projects due to its limitations.
Here is a very important article on VSS: http://www.highprogrammer.com/alan/windev/sourcesafe.html
Another option is to create custom code to export the VBA solution using Application.SaveAsText (), a partially undocumented Access API function.
