I am building an application that updates a table in Sybase 12.5.3. Here is my situation.
How can I connect to Sybase 12.5.3 from vb.net 2010? In the past, I have used ODA to connect to Sybase and it worked fine.
The problem is that ODA was removed from VB.net in versions 2008 and 2010.
These Visual Basic versions are now using ASE to connect to Sybase but ASE is for Sybase 15.
I tried using ODBC but the drivers that come with VB.net are for Microsoft SQL.
I tried connecting to Sybase using MS SQL drivers. I was able to connect, but the execution did not work that well.
how to connect and how to execute a stored procedure with input and output parameters?
for example, if i want to create a program that that takes the result of the calculator ( i mean the default calc of the windows ), or the result of any program, and keep these results in my created vb program, or to manipulte these results, is it possible?

the file is a 2003 access file if i am not mistaken. and it is shared on network. so multiple users (not too many, max 50) will use it at same time. what is the best connection to use? i have to mention that i don't want to use data controls. i want to use sql commands to fetch data and manipulate data on the form controls myself. i know there are various connection ways like strings and adapters. not sure which one is better.
