Re: Using C# and I get an error 'Infopath cannot open the selected form'

So it looks like I get an error anytime I use code in a form. I created a form and added a button and added code behind the button for a clicked event.

Code:

Public Sub CTRL1_5_Clicked(ByVal sender As Object, ByVal e As ClickedEventArgs)

MessageBox.Show("Hello World")

End Sub

And then when trying to preview I get the error 'Infopath cannot open the selected form'. I've tried messing with the trust settings and deleting the cache with no luck

Using C# and I get an error 'Infopath cannot open the selected form'

Here is the situation:

I am trying to code a form to access data from our AD. I enabled the form for Full Trust, placed the form code in place and it will build without errors. When the form trys to open (preview) I get the error. Whe I try to open the form from the template I get this error:

Form template: file:///REMOVEDFILEPATHFORTHISTHREAD.xsn
InfoPath cannot open the selected form because of an error in the form's code.
System.Security.SecurityException, mscorlib

The action that failed was:

The type of the first permission that failed was:
Microsoft.Office.InfoPath.InfoPathPermission
The Zone of the assembly that failed was:

My question: Is this a trust issue with the form? I can't even preview it so it's got me confused
