Hi, and thanks for the tip.
Further to this, I am looking to solve the following problem and I'll be thankful to you, if you can assist.
A service written in C exposing some normal and call back functions, running under Windows. For this Service, I have its TLB, dll and Lib files. I need to know how can I hook to the service from C# and call its function as well as subscribe to the delegates?
What I have done is successfully DllImported and called the function from the imported dll; however, I am unable to directly call the Running Instance.
