per emails from nSoftware, I believe i have to use the SDK to query for Items (or update to a newer ver$ion). So these are the 2 items ("563" and "ND-105") that u are pushing over? Is this code performing a search first though? I find that it errors out if some things... like items... are not unique.

XmlElement itemNameRq = inputXMLDoc.CreateElement("FullName");
           itemNameRq.InnerText = "563";
           itemQryRq.AppendChild(itemNameRq);

           itemNameRq = inputXMLDoc.CreateElement("FullName");
           itemNameRq.InnerText = "ND-105";
           itemQryRq.AppendChild(itemNameRq);

>There is a section in the above where I'm doing 2 "CreateElements" with "FullName". Which is the item key. I don't have the SDK with me, but I remember that you can pass either FullName or one other column to retrieve individual items.

>This above isn't exactly perfect. It's a combination of reading how to accomplish XML in C# 2.0 and QB examples which are done in V1.0, I think. The books recommend XmlDataDocument, added in V2.0, but I haven't tried it yet.

>>Avoiding your checkbox question, are you searching the QB database before adding new ITEMS or are you just flagging items as having already been exported to QB? I have been using "nSoftware's IBIZ QB control" (http://www.nsoftware.com/ibiz/QuickBooks/) and the earlier version that i have doesnt provide for searching of items. Do you have some code u can share on how thats done?

>>>I'm creating a little system to interface to quickbooks inventory. I want the user to hit a button that will populate the system with the inventory items from qb. Then click a checkbox in the grid that will indicate which items that are necessary for the process.

>>>Using the smarttags I've added a checkbox column to the grid. Then in code, after I've retrieved the xml file from qb, I add 2 more columns for the item key and description.
