Managed classes and structures are simply types. If they are part of an assembly that is exported to COM, they will be exported along with all other types. There is really nothing special that you have to do in order to pass a class or structure as a parameter to a method. Within the typelib, each class or structure has its own COM identity (a unique Guid). This enables COM clients to create instances of these types or reference them as they are passed to methods. In effect, they have now become custom COM types that are defined in the typelib. In the case of classes, you can choose to expose them using the default class interface, or you can define your own interface that identifies the properties and methods of the class. The preferred way is to always define your own interface. As an example, consider this managed interface that we want to expose to COM: //define an interface for account services public interface IAccountLookup { IAccount RetrieveAccount(int acctId); void UpdateBalance(IAccount account); } Both defined methods use a custom type (an interface) named IAccount. Obviously, for these methods to work via COM, the COM client must know how an IAccount is defined. We need to define and export this type to our typelib. Let s define the IAccount interface like this: //define an interface to expose class properties //to COM clients public interface IAccount { int AccountId {get;} string AccountName {get;} decimal Balance { //marshal the balance to COM as CURRENCY [return: MarshalAs(UnmanagedType.Currency)] get; //prohibit setting of balance property via COM [ComVisible(false)] set; } }

The main program file starts with a whole series of compilation modifiers These change the way the project is built, allowing you to include or exclude different features to suit your requirements as discussed previously This also helps keep the resulting hex file as small as possible, but remember that some features are dependent on others The first option is DEBUG, which causes the OBDuinoMega sketch to skip the initialization of the OBD interface and move right along as if it was attached to a car, even if it isn t It also causes calls made to retrieve OBD values to return hard-coded values so the system will look like it s working, but in fact it s just faking it.
