Previously working IFS form now displays this error message when opening:

 The custom code in the form cannot be run. This functionality may be deactivated on the server. For more information, contact the server farm administrator.

This is a sandbox solution deployment to a SharePoint 2010 Form Library.  I've attached the xsn.  Any help is appreciated.

 Have you spoken to a SharePoint admin? It sounds like a SharePoint issue; perhaps an admin turned off sandboxing.

Hello Ramu55,

even though I have not a "ready-to-run" solution for this problem I will try to help a little bit..

This error occurs because of some code in a sandbox which is partially trusted is calling a dll in GAC which is having full trust. And the solution to this is, in the code which goes as dll in the gac inside it just decorate the namespace with the following line:

[assembly: AllowPartiallyTrustedCallers]

I don´t know if you use "code-behind" in your form but if you do you have to consider that you can´t use all of the objects in .Net framework. For instance (as I have heard) you can´t use SPSite or SPWeb object but this statement is with no guarantee as I´ve never tried it for myself. A complete list of limitations in a sandboxed solution will you find here:

Hope that helps a little bit..

 Hello Karsten,

Thank you for your response.

I do have code behind, and all of the assemblies I have have been tagged for allowing partially trusted callers.

I tried publishing my forms on otther vms/environments and it worked, finally after doing some more log reading and reading on technet I was able to get it working by upgrading the timeout value of the user code service.

SPUserCodeService.Local.WorkerProcessExecutionTimeout = 40; //default is 30 seconds

It depends on the performance of the particular environment, hence on a multi-server farm I was not getting this error, while on vm it was failing. 

Check this MSDN article http://msdn.microsoft.com/en-us/library/gg615462.aspx. though generally one should consider consulting the sharepoint admins before changing any of these values on production environment.

thanks and regards

Ramu
