Re: UserName bug(?) for forms published to SP library

Yes, it does work. I wasn't aware of the Advanced option to "Show a notification for managed code errors." With that turned on I do see the Security exception. So feel free to move this thread out of the Bugs folder : ).

Now if I can just get around those Access database connection issues without having to fully trust the *site* (and thus lose the ability to call Environment.UserName without a fully trusted *form*), all will be well.

But, it works and fills in username, right?

I have it in Trusted Sites. If I puthttp://<my server name> in IntraNet zone, when I click to the button to query an Access db I get a dialog stating "This Web site uses a data provider that may be unsafe. If you trust the Web site click OK, otherwise click Cancel." If I click OK I get another dialog stating "This Web site is using your identity to access a data source. If you trust the Web site click OK, otherwise click Cancel."

When I add the site to Trusted Sites I don't get these dialogs.

Sounds like a permissions issue. Is this running Domain trust? What zone is URL in? It should be in IntraNet zone not Internet or Trusted. Please check in IE.

UserName bug(?) for forms published to SP library

pmbarnes — Mon, 15 Aug 2005 22:23:02 GMT

I've got a managed form I'm publishing to a SharePoint Team site Forms Library on a domain controller. I've discovered that calling Environment.UserName in the form's OnLoad event handler essentially causes a silent runtime error, preventing any code that follows in the handler from executing. I think this bug can be reproduced by creating a simple form, adding an OnLoad event handler and then putting the following in the handler:

e.XDocument.UI.Alert(Environment.UserName)
e.XDocument.UI.Alert("test msg")

This will appear to work fine in Preview mode. But when I publish this template to my SharePoint Form library and run it from the server or a client box none of the alerts appear when the form loads. If I reverse the above two lines of code, the "test msg" alert will fire and nothing else.

Has anyone seen this?

UPDATE: I think this is an issue with Full Trust. I had seen postings from others that Environment.UserName didn't require Full Trust. But maybe they're not on a DC. I just signed the form with a self-issued cert and it did access Environment.UserName when I opened the form from the Form library on the server. When I tried the same on the client box I got an error saying the form could not load because the cert either expired or was revoked. Must be that it was self-issued. This is progress. I will post back if I've resolved this. Might be helpful for someone in the future.
