I'm trying to write a program to call Quickbase and retrieve a database and put it into an array. It's a contacts table that I need to be able to query and select different fields according to letterheads, memos, etc. I've tried to do this three different ways.
1.) Find a direct port or some way of accessing Quickbase directly, similar to connecting to an oracle database or MS Access.
2.) Export the table to MS Excel and read the data from a spreadsheet.
3.) Opening a web browser in a background processes and login to the Quickbase account, then navigate using the little XML knowledge that I have.
I just can't find a good way to do this. Any ideas or can give some help on the code to do any of the ideas?
