InfoPath Dev

Hi ,

I am working on an upgrade project from Infopath 2003 to 2007. In IP 2003 code there is a method called _startup which seems to be initializing XDocument and Application. But no such method is found in the IP 2007 converted project. My code accesses these objects and I get a null exception because XDocument is null. I was wondering if we have to specifically initialize Application (or Xdocument) to access it later?

Also, it looks like there are two application classes , one in Microsoft.Office.Interop.InfoPath and one in Microsoft.Office.InfoPath. WHats the difference between those?

Hi,

"Microsoft.Office.Interop.InfoPath" is a infopath2003 assembly. and "Microsoft.Office.InfoPath" is a infopath2007 assembly.

If you want to work with infopath2003 assembly, add “microsoft.office.interop.infopath.semitrust.dll” assembly to your references. This assembly file is located in “C:\Program Files\Microsoft Office\Office12” folder.  

Hello,

Go through the below link to get more information on Xdocument,

Hi,

In IP 2007 we use XPathNavigator to access the nodes.

In IP 2007, there is a method called InternalStartup(). In this method, write the following code.

XPathNavigator XDocument = this.MainDataSource.CreateNavigator();

Thanks for the replies! After a little research I found that in the Infopath 2007 object model the XDocument class was renamed to the XmlForm class.

I will have to access Me.Application.XmlForm.Item(0) to get a reference to XDocument (in 2003 version)

Thanks for posting this link to help others!
