C# Threading Problem (GUI???)

I am in a rush to finish a home automation program. Basically we have a data management class that keeps track of all our devices, and future events to be handled. We have a C# GUI running, but we wish to run the future event function as a thread running in the background triggering events when they are to be triggered. We are having a great deal of problems trying to do this. If anyone can help us share the same class (HomeController) with both the GUI thats maintaining the program and a thread that is running the event handler, it would be a GREAT help... my email is [email protected] or [email protected]
