I Have these Programming Project In School Using Visual Basic 2005 Express, we were assigned to do a First Come First Serve Simulator however it's just my Second Year in College and I'm No good in Programming cause I'm not majoring in IT.. Any one can help me on how to start?

I would start with reading your textbook and then break your project down to the smallest piece you can figure out on your own and if you get stuck post back as to what your problem is.

can you be more specific and give details of ur college project? that would help.

I'm totally Screwed with these:'( I can show the Screen

It's somewhat like the uploaded Image

It calculates a Job Inputed and shows out an output

Sorry for the Second Post here's the exact Screen Sample

I Manage to do that FCFS Codes now My Next Problems is with the Shortest Job First

I Have these Code but at Runtime it's totally Screwed. anyone who can help me with Shortest Job First CPU Sceduling :
