There's no way to convert an mdb into an exe.
Tony Toews lists some products that purport to be able to convert Access
apps to VB at
http://www.granite.ab.ca/access/accesstovb.htm but the general
consensus is that they do an incomplete job at best, and that you're usually
better off rebuilding the forms in VB (there are simply too many differences
between the controls available on Access forms vs. those available on VB
forms)
Another option, though, is to purchase the appropriate Developer edition of
Office so that you can distribute your application along with a royalty-free
run-time version of Access so that users who don't already have Access
installed can install the run-time version and use your application. Tony
has information about this at
