Openfiledialog

[rob]

Hi. I'm using a button to pop up an openfiledialog box in a infopath form.
After I select a file valid file on the dialogbox and click ok, I get the
following error message:

System.Security.SecurityException

Seems like I cannot access files on the local hard drive. Maybe there's
something else I need to reference in the project? Thanks!

Hi,

You don't have the right to do that you need to have full trust or
domain trust to do your operation.

See on the msdn there are explanation and example about permission.
