I have an accounting system written in VFP6 and a quotation system written in VB6.
When the user goes into the invoicing, I would like to automatically get the invoicing lines (details) generate by VB6. Something like calling a VB6 application with parameters (that will provide the VB quotation system with the needed information to select the good quote) and get the result so I can insert it in the VFP invoicing system.
Should I use OLE, XML, whatever?

Thanks
Eric
