I have got the complete vb6 application for doing graphic and costing estimation. I am currently using microsoft access database.
The problem is: my client is currently using a quickbook application for their accounting package (for paying employees, suppliers and making an invoice for the customer).
As far as I concern, I need to access the item and pricing information in visual basic, so they can use my program without any data redundancy. Furthermore, I need to insert some data into quickbook table.
There is no need for quickbook and vb6 to join into one single program. But I want them to share the same data / database.
What should I do?
