Re: Closing InfoPath on form submit

it seems the path of the field is different, go to design mode in your form. In design tasks, click Datasources, go to your field and right click and select copy xpath, paste the same as an argument to root.SelectSinglenode(XPath, this.NamespaceManager).SetValue(formName)

Thanks for the response. I've added the change but still get an error:

System.NullReferenceException was unhandled by user code
Message="Object reference not set to an instance of an object."

StackTrace:

Please see the attached image for the C# code and error.

mark-scott:
root.SelectSingleNode(
"//my:formName", NamespaceManager).SetValue(formName);

change it to

root.SelectSingleNode("/my:myFields/my:formName",NamespaceManager).SetValue(formName);

Closing InfoPath on form submit

I have designed a form with Intopath and it is working well, however I cannot close the form on Submit. I have created some code as follows:

{
    public partial class FormCode
    {
        // Member variables are not supported in browser-enabled forms.
        // Instead, write and read these values from the FormState
        // dictionary using code such as the following:
        //
        // private object _memberVariable
        // {
        //     get
        //     {
        //         return FormState["_memberVariable"];
        //     }
        //     set
        //     {
        //         FormState["_memberVariable"] = value;
        //     }
        // }

        // NOTE: The following procedure is required by Microsoft Office InfoPath.
        // It can be modified using Microsoft Office InfoPath.
        public void InternalStartup()
        {
            EventManager.FormEvents.Submit += new SubmitEventHandler(FormEvents_Submit);
        }

public void FormEvents_Submit(object sender, SubmitEventArgs e)
{
// Get a reference to the main data source
XPathNavigator root = MainDataSource.CreateNavigator();

// Generate a name for the form to be saved in SharePoint
string formName = Guid.NewGuid().ToString();

// Set the name of the form on the data connection
root.SelectSingleNode(
"//my:formName", NamespaceManager).SetValue(formName);

// Submit the form to SharePoint
DataConnection spConn =
DataConnections["SharePoint Submit"];
spConn.Execute();

// Indicate success
e.CancelableArgs.Cancel = false;
}
}
}

I uploaded the form back to sharepoint and tested with the following result:

Object reference not set to an instance of an object.
   at IT_Process_Form.FormCode.FormEvents_Submit(Object sender, SubmitEventArgs e)
   at Microsoft.Office.InfoPath.Internal.FormEventsHost.OnSubmit(DocReturnEvent pEvent)
   at Microsoft.Office.Interop.InfoPath.SemiTrust._XDocumentEventSink2_SinkHelper.OnSubmitRequest(DocReturnEvent pEvent)

Any ideas?
