C Sharp Login with different user privilege

Hello

I have an application that is basically built on Tab control. I have 8 tabs and i need to have different domains(e.g Admin, clerk, bursar, secretary) on my login where when a user under a specific domain clicks on a certain tab, an event is generated that prevents him from viewing the content of that tab

Any advice please???

It will be better to define different roles & privileges; Then we can show / hide different tabs based on the privileges of the logined user.

Web app, or desktop? (It helps to be precise in your initial question.)

Okay, so you need to manage roles yourself, unless you want to use the standard Windows account properties. I think you can get the group name and you can definitely get the domain and user name.

I was thinking of it this way...

    private void Form1_Load(object sender, EventArgs e)

    {
    if ((Thread.CurrentPrincipal.IsInRole("admin"))) // admin in this case should be a domain name.
    {
    tabPage4.Hide();
    }
    else
    {
        MessageBox.Show("You must be a member of the Manager or Administrator's roles to view username and password information", "Insufficient Permissions",
            MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
    }
}

But now instead of

CurrentPrincipal.IsInRole

put something that will read the domain name. Something of that sort.
I'll appreciate any help
Thank you

Adding Reference to Dll (Class Library ) & Using statements

Hi,
I would like to know:
1.what happens when you add a reference to a Class library in dotnet.

2.Is it something like a "implicit" linking in C++?

3.Can I make the library statically link to the exe?

4.And does the dll in dotnet internally have implementation for DLLAttach, Detach?

1. It is similar to compile-time linking in C++ in that the CLR automatically loads the library

2. A little bit.

3. No. The CLR takes care of runtime loading and linking automagically. You are not allowed to have anything to do with it.

4. All necessary runtime loading and linking is taken care of by the CLR.

Thanks for the reply mate.
I'm trying to look into the internals of managed world.

The document says "CLR is hosted"? Does that mean CLR is per process stuff? is it not system wide?

The CLR is 100% a user mode component. No kernel mode stuff at all.

Technically, the CLR maintains a single process space, and all .NET "processes" are segregated within that one process space. These are called Application Domains. The fact that they are really within the same process makes inter-application communication much simpler and faster.
