InfoPath Form & Ressources

Question

Hello,
i want to create a ressource file which is a file which contain the connection string for connectivity, and this file will be used by the InfoPath Form when it's hosted.
So i created a C# project associated to the InfoPath Form template, and i added the code which open the file and read the ConnectionString and use it later to open a connection to SQL Server DB.
When i debug the code, (Preview the InfoPath Form), it's function, perfectly.
But when i deploy to the server, and i execute the Workflow, and the task associated to that IP Form template, is created it does not function !!!
What's the problem ??
Thanks !
