Security Exeption when calling Webservice with .NET Code in Infopath Document - opend over Sharepoin

[Benjamin Kremer]

Hello Everybody,

my project seems to be going to an end. But there is one little Problem :

I made al little Infopath- document which gets it´s data from .Net Code, the
date is pasted to the DOM with the XMLDocument.AppendChild() or
..insertBefore Method.

The .Net Code get´s it´s data from a XML Webservice, which gives it´s
results via a DataSet. The .Net- Code splits the dataset into XMLNodes and
adds them to the Document- DOM.

Everything works fine when I open the Form locally. But when I publish this
form to a Sharepoint Document Libary, I´ll get the following error by
calling the .Net Code in the form (Sorry, German):

Anforderung des Berechtigungstyps System.Net.WebPermission, System,
Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 ist

at CPP_Win_Server.CPP_Win_Server.btnGetData_OnClick(DocActionEvent e)
at
Microsoft.Office.Interop.InfoPath.SemiTrust._ButtonEventSink_SinkHelper.OnClick(DocActionEvent
pEvent)

Due to the line "at billy.Service1.GetWMIData(String strServername, String
strUsername, String strPassword, String strClass, String strProperty)
", it seemd that the Webservice- Call fails. But I´ve no idea why ...

Thanks for Support !

The error message indicates that you need to fully trust your form. Try
making your form fully trusted.

You should also be able to do it with a specific .NET policy, though I don't
know which one off the top of my head.
