Dim userNavigator As XPathNavigator = mainDomNavigator.SelectSingleNode("/my:myFields/my:field1", Me.NamespaceManager)

"check to make sure you have fulfilled all necessary security requirements"
and
"Use a certificate to obtain the required permission"
and
"if an assemply implementing the custom security object reference other assemblies, add the reference assemblies to the full trust assembly list"

the exception apper when i use Xpath

can any one help me ,

try signing the form, go to tools -> form options -> security and trust and sign the form template.

If that does not resolve your problem you might have to give full trust to your form, but i guess signing should do it

thank you for your Replay ,

i sign the form template and the Exception thrown agaen ,

i have to leave the security level at domain , 

 because i well work with sharepoint ,

i need the selution in domain security level ,

 The code you posted there should work fine in domain level trust.  Is there some other code in your form that might be causing the error?

thank you Jimmy for your Reply ,
