I am currently trying to develop a website which allows users to input some C prog codings into a field. when they clicked submit, their input will be compiled and errors will be reported to them if there is any, else they will be prompted to either open/save the output file. I am developing this system using VB.NET and ASP.net collaborating with GCC under Windows XP environment. *Assuming that all my users are running on Windows platform as well. I need help on this and if possible simple sample codes as well. Thanks for the help and guide. regards, dennis
