That it is giving you a security error is what doesn't make sense.

Please also check that the object you are trying to get .Count on is valid and not null. This shouldn't give you a security error... but I'm at a loss for what could be going on. Doesn't appear that there would be any timing issues or anything.

Hi, I have fallen foul of that before.....

But I have double checked - in this case it is in a Changed event. When run stepwise in debug, I get the error message, then when repeating the line of code it works ? Very odd.

Why would I need any extra permissions for accesssing data from my main data source which is within the form ?

In the Changing event handler, the DOM is readonly.

In the Changed event handler, be sure to examine the e.Operation property to only process your code during the right operation (i.e. Delete, Insert, Value Change, etc)

Hi - I am using Infopath 2007 and VB.

I have a form with several bits of code behind the Changed/Changing events. The form's permissions are set to automatically determine level required.

I have started getting errors when running code.....

Dim grp As String = "/my:ApplicationGroup/my:ApplicationContactsGroup/my:InvistaITContactGroup"
Dim concat As String = ""
Dim itgroup As XPathNodeIterator
Dim navout As XPathNavigator
itgroup = Me.CreateNavigator.Select(grp, NamespaceManager)
Dim norecs As Integer = itgroup.Count <-------- at this point I get the error

System.Security.SecurityException was unhandled by user code

When I am running in debug mode and have had the exception I go into 'enable edit', and re-run exactly the same lines of code and it works ........ so can't get to the bottom of the problem.

I don't understand why accessing a group in my main data source would give this error - and why it doesn't run in debug - but once it has had the error and I run the same lines again it works - can anyone explain where I have gone wrong.....

This is happening in several places in the code. The consistent thing is that it is always on a .count of a navigator where the problem occurs.

Thank you.
