Hi, I'm a computer´s student and have some problems with a work I have to do. My teacher has an application written in Haskell(with GUI) and he wants I work on Visual Studio.net to make a GUI in C# and its buttons have to call his Haskell'application . I'm very disoriented and help'needed.Please!!

Option 1: have your C# application send faked .NET GUI messages (button clicked, text entered, and so on) to the Haskell GUI, using SendMessage or whatever it's called. Option 2: on the Haskell side, implement a little textual command language that allows you to drive the Haskell app; connect it to a socket; arrange that the C# app sends the commands to the socket. Option 3: use the Haskell FFI to connect to a C wrapper that implements whatever interface you like; use the .NET native support to talk to that interface. Option 4: compile Haskell to IL using the (experimental) switch on the GHC compiler. What does your teacher want you to do? Reply to the list, please, not to me only. --KW 8-) -- Keith Wansbrough http://www.cl.cam.ac.uk/users/kw217/ University of Cambridge Computer Laboratory.
