As I indicated in my Quicbbooks Part 1 of never post, I would post some Microsoft Access and other Quickbooks source code and blog entries, rather than do a more detailed step by step explanation.

I hope this is helpful.

Quick Explanation

You can parse Quickbooks response using a ICustomerRetList – and I may post that code later – BUT it is less forgiving for missing data, requiring error checking to catch that. Using XML and the DOMDocument object lets me act on data returned and also navigate to childNodes when they exist.

This routine returns all active customers and then parses the returned XML. There is a call to a sub-routine that runs for each returned record. I don’t include that sub-routine. It simply checks to see if the customer data exist in my client’s SQL Server.

If the record already exist, based on the Quickbooks customer ListID, it updates it. If it does not exist, it creates the matching record in the client’s customer database. What you do with each returned customer record would, of course, be based on your client’s underlying data.

Set smgr = New QBSessionManager

                    strURL = cust.Item(x).childNodes(y).childNodes(1).Text

    Next
' THIS IS THE SUB ROUTINE THAT CHECKS FOR THE EXISTENCE OF THE QUICKBOOKS LISTID IN MY CLIENT'S DATABASE AND UPDATES OR CREATES IT AS NEEDED
    UpdateCustomerRec strListID, strTimeCreated, strTimeModified, strEditSeq, strFullname, strName, strFirstname, strLastname, strEmail, strURL
