I am writing an application that pastes unformatted text into various fields in an application called cerner. Cerner runs via a VPN that is setup by Citrix software (I think). All the cerner applications seem to run under the same windows process.

Does anyone know of a good resource online that I can use to figure this out? I have been looking but I dont think I know the correct terms to use.
