My VB6 application communicates with Intuit QuickBooks desktop via special version of XML language qbXML. The application contains a pretty big number of procedures to send and receive data to and from QuickBooks file located on the company server. It eliminates double entry of data into 2 databases - MS SQL and QB file. All operations are done with SDK support.
The new Intuit's approach is QuickBooks online. Intuit offers SDKs for Online edition as well, but unfortunately there are 3 of them only - for .NET, Java and PHP. Nothing for VB6.

Did anybody her work on the transition from Desktop edition to Online edition with VB6? To rewrite a pretty big VB6 project with new technology is not an option yet. It would be great to find the way to use existing VB6 code with QuickBooks Online edition.

Any help please.

Thank you
