C# How to output to GUI when data is coming via an interface via MarshalByRefObject?
- by Tom
Hey, can someone please show me how i can write the output of OnCreateFile to a GUI? I thought the GUI would have to be declared at the bottom in the main function, so how do i then refer to it within OnCreateFile?
