RegistryKey rkHKLM = Registry.CurrentUser;
RegistryKey rkRun;
String site = "whatever site";
String regPath =("HKEY_CURRENT_USER\\Software\\Microsoft\\Internet Explorer\\Main");

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.
|
|
|
|
|
Please give me a simple guide line...
Thank you

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

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")))
{
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

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.
The difficult we do right away...
...the impossible takes slightly longer.

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.
The difficult we do right away...
...the impossible takes slightly longer.

Thanks for the reply Richard.
I'm trying to dig a little deep into it but most of the links show up a blunt high level Block diagrams , explaining the stacks in the framework.
I need to a pointer to understand low level details of how CLR is invoked to deal managed Applications.
Anywhere you can point me to?
I want to know: When I execute a managed App, how does the OS route the exe to the CLR?
Or CLR is mapped to every process? If CLR hosts all the managed Apps as domains? then how does it over ride 4GB limit per process in a 32bit system?
|

Yes, those certainly are important questions.
I'm not sure where to find such detailed information. Perhaps the MSDN blogs?
Good luck.

Working with Visual Studio 2008. My tutorial indicates that when a SQL database is created the solutions explorer changes to the database explorer.
The view changed on the first attempt but has not been seen since. Looking for guidance for troubleshooting if necessary. Or... was the view only shown first creation. Guidance sought

Sounds like a Visual Studio question, not a C# question.

Much thanks for your reply. Please know that I checked the discussion list and did not see Visual Studio. Woudld be so appreciative for a link.
* Just saw Visual Studio in this forum for the first time. Much thanks
Cordially,
