ASP.net problems

[arpanmukherjee1]

i am relatively new to ASP but well educated on C# & C

i have multiples problems.

1. i want to develop asp page like the codepad. now limiting to compiling only C codes. i choose tiny c compiler . it says it can take program inputs from standard input but on win xp it says "declaration missing"

2. how to save a text in the textbox and save it in a file and run it consecutively. giving commands is very easy . See :How to Execute a Command in C# ? - CodeProject

3. how to display color highlighting syntax in textbox ??

pl. try to answer from purely academic point of view. try to give links to solutions that u think r the most appropriate.

give any other alternative command line c compiler
