InfoPath 2k3

[swatch]

Hi,
My problem deals with Web Service & System.Net.WebPermission

I created an InfoPath Visual C# projet with Visual Studio 2k3 and added a
form (called toto).
When the form is load a Web Service is called to retreive data stored in a
DB (this is not the issue).

In design mode I can preview the form. The Web Service return the desired
informations.
Everything work fine.
Then I published the form on a shared directory
(\\SERVER\SHARE$\DIRECTORY\toto.xsn)

When I double click on \\SERVER\SHARE$\DIRECTORY\toto.xsn I obtain the
hereunder error

System.Security.SecurityException
Request for the permission of type 'System.Net.WebPermission, System,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Try configuring code access security for your web service. For more

Hi Clay
Thanks a lot for responding.

I found the solution monday :

1) I installed a Certification Authority in my organization.
1) I created a certificate that is suitable for digital signing
2) installation in the Personal Certificate Store of each user's computer.
3) I signed the form Tools | Form Options | Security
4) I deployed the form
