Custom task panes and managed code

[Rob Blitz]

Is it possible to change a custom HTML task pane from within managed code?
I've been fiddling around with this a bit and keep getting a security error.
I though that possible because I had to include a reference to the mshtml
..NET assembly to manipulate the HTML DOM that I was violating the domain
security level of my form, so I made the form trusted but I still get the
security error.

Can custom task panes only be manipulated in trusted forms? If not, can you
manipulated them from within managed code?

Rojer Jennings' description of how to change the managed code security made
it work: http://www.oakleaf.ws/InfoPath/fulltrust.aspx

Since it's a client config however, I would have to back off of using
managed code in my form or make the form fully trusted. Unless you can set
these security configs from within group policies.

"Communication between the taskpane and managed code business logic requires
that your managed code has FullTrust permissions (because it needs to call
into unmanaged code). If your form needs to communicate with the taskpane,
try to stick with script for your business logic, if you can. "
