Changing Ms access Culture

Dear Experts,
I am working on a project developed in vb.net, and using MDB files as databases,
recently we have encountered a serious problem as we tested our application abroad (Germany) ,
we have found out that our application can't handle the German decimal separator , they use a comma instead of a dot, what happened is every parsing from string to number got messed up ,
for example parsing the number 4.23 would result in 423, and many more problems.

as a temporary solution until we code all the project correctly with globalization format parsing,
we want to lock our application to en-us culture only, which means the application would display an "en-us" cultureInfo only at the UI and data.

so i have found a way doing that in .NET framework , it is working great ,
the problem now is the connection to MS Access, right now if i use a comp using German Regional settings , i see my application the same as en-us but when linking to the database ,
the db still on German regional settings which creates various conflicts ,

THE QUESTION:
is there anyway i can set a connection to access mdb files so the connection will be in "en-us" format??  ( dates numbers ....) on insert queries should be en-us all the time.

any tip on the subject will be very helpful thanks in advance!!
