InfoPath Dev

I'm using InfoPath 2007. I try to retrieve the records from SQL server and update the form's field but system prompt the following error when execute the code "MyConnection.Open();"

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

Please advice and suggest the solution.

Thank you.

Your error indicates that this is a security issue.

1. Check your permissions.
2. Try creating a full trust form.

Thankx Greg Collins. After set to Full Trust Form and the error no occur anymore.

Great! Glad to have been able to help!
