SP Gugu: How to Programmatically change a list item's ContentType by WSS WebService?

Please, help! I can't find any information on MSDN under WSS3 webservices List.UpdateListItems topics

how to programmatically change a list item ContentTypeId

Calling SharePoint list service like: (adding a list item)

XmlElement elBatch = doc.CreateElement("Batch");

elBatch.SetAttribute("OnError", "Continue");

elBatch.SetAttribute("ListVersion", "2");

XmlElement el1 = doc.CreateElement("Method");

el1.SetAttribute("ID", "1");

el1.SetAttribute("Cmd", "New");

XmlElement field1 = doc.CreateElement("Field");

field1.SetAttribute("Name", "ID");

field1.InnerText = "New";

XmlElement field2 = doc.CreateElement("Field");

field2.SetAttribute("Name", "emp_no");

XmlNode response = listService.UpdateListItems("Tasks", elBatch);

In order to update metadata you need to specify reference to the file that you want to update, here I found answer to my question:

For me goal was to upload files to Sharepoint Programmatically and update metadata (Indexes, Column information) using Web Services.

What is the corresponding way to set an SPListItem's ContentType directly using the WSS object model

the desition was found:

XmlElement field1 = doc.CreateElement("Field");

field1.SetAttribute("Name", "ContentType");

field1.InnerText = "theContentTypeName";

Hey there,

I just came across this problem recently and have a solution just in case anyone stumbles upon this thread.

// Grab the content type from the list so we can get the id
SPContentType spctExampleContentType = splExampleList.ContentTypes["Example Content Type"];

// Create the new item
SPListItem spliNewItem = splExampleList.Items.Add();

// Now set the content type id
spliNewItem["ContentTypeId"] = spctExampleContentType.Id;
spliNewItem.Update();

// now we have access to set all the content type fields

spliNewItem["Content Type Field 1"] = "Row";
spliNewItem["Content Type Field 2"] = "Sham";
spliNewItem["Content Type Field 3"] = "Bow";

Pretty self explanatory, I'm not looking at my code right now but that is the general jist of it.

Hope that helps!!
