Edit Field Values in hosted form

[Josiah Smith]

I have a hosted InfoPath form in a Windows Application, and I am using the
demonstrated code to change views in the form listed here
http://msdn2.microsoft.com/en-us/library/ms406041.aspx.

I have some functions in the form, created at design time in the InfoPath
design mode, that require fields to change to hide a section, for example, or
to save via http file manipulation.

Is it possible to us C# from a .NET environment to change fields within the
data source of a hosted infopath form?

Thanks,
Josiah
