InfoPath Dev

I am a new developer of InfoPath, I read article #12298;Task Panes that Access Managed Code Require Full Trust Security#12299;. In this article , said:” Managed code forms that have a custom task pane require full trust security.”
Can Everybody give me a example how to make Managed code forms have full trust security? Thanks.

In the Designer, go to Tools->Form Options->Security. Deselect Automatic and select Full Trust. You'll have to either sign the form or run regform to create an msi. To sign the form, create a digital signature on the same dialog and attach it. To run regform, download the InfoPath SDK and type regform -? for instructions.
