Thread: chat system

That sounds like a complicated application to design and write. How long are you planning to work on it?
Do you have any one to help you?

There are several examples of chat applications from students here on the forum.
You should be able to find them with search.

That could be long enough.

This is a very large and long term project it sounds like. Start by picking a design pattern and working through it. Most college programs can use a waterfall approach. Design, Code, Test. Start by defining what you want to make then break it up into parts and get more detailed. Sounds like you need separate roles for students, teachers, and whoever else. Define who goes into these roles and what they are allowed to do. Only after you have all of this stuff defined should you start coding.

Designing apps is the fun part. Once you have the design, writing the code can be boring.
You need to spend the time designing the app.

help ne with the algorithm

What design do you currently have?

I must disagree Norm, I live for the code! Although a good design session can come up with some pretty cool stuff.

I don't see a complicated "algorithm" here. Once you have your design, the code should just fall into place. If you run into networking issues you need to list those specifically and we can help out. If the roles portion is what is holding you up, I suggest having each user object with a role value then when you load your GUI or execute a function, do a check that the user can see or do it. If they cant, disable the option or display a message that they do not have adequate permissions.
