I have a c# application with windows form for updating and retrieving some
database table records. lets call it form1. I also have another  application
in vb that extracts data from the web but used the same database table as
input to direct its operation. the data in the table is not useable directly
but need a bit of transformation as done in the form1.

how can I make retrieval functions in forml to the vb application? use the
same package name but in different project?

I want the vb app to control the form in terms of selecting the record but
only if the form1 is instantiated by the vb application.

if I just use the instantiation of application method, I don't know how to
make available the required functions and the called internal function
without the public

thank you for your time and expertise.
