Okay, I have now set Trust=Full in web.config, added my assembly to the SafeControls list in web.config AND added my assembly to the GAC and I STILL get a SharePoint CAS error!!!!!!

Here is the error from forms services:

writing a file to SharePoint on button click?

CraigW — Mon, 23 Mar 2009 15:04:53 GMT

Hi all,

I have a forms-services rendered form and I would like to create file based on some of the contents when a button is clicked.

I have managed to generate the file contents fine, but I CANNOT get it to write to anywhere!

My first thought was to write the file back to another SharePoint document library, which I thought would be dead easy, but I can't get past SharePoint CAS, even when my InfoPath project dll is deployed to the GAC!! Has anyone ever managed to get that working? I've tried a custom policy but that didn't work either.

As an alternative, I just tried using HttpContext.Current to send the file to the user, but that just returns a completely un-useful 'Critical Error' in forms services, with no other information.

So, how does everyone else do this?

Thanks,

Craig
