How can I get the login name of the user currently logged into Windows as a
string?

Thanks,

Well, in .NET 2.0 is simpler: My.User.Name, although it returns the domain
too.

FYI, the My.User.Name functionality does not work for a console app.

The My namespace doesn't exist for console applications.

Well, with conditional compilation constants it's maybe possible to add it
to console applications too, but I fear that this would be justifiable only
for using a simple method which is mainly a wrapper around .NET Framework
methods.

Is there also a (simple) way to have Windows authenticate a Username /
Password combination?
I need that for an application security lock (after xxx minutes of
inactivity)

Hi,

Imports System.Security
Imports System.Security.Principal

AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal)
Dim myID As WindowsIdentity = WindowsIdentity.GetCurrent()
Msgbox("The Current User is : " & myID.Name)

Regards,
Cerebrus.

I saw your post just now and have a question, Carlos.

The definition of the Environment.Username property suggests that it
would get the name of the User who launched the current thread or
process. Now, in some cases, that username could be SYSTEM or
LOCALSERVICE or NETWORKSERVICE.

But I think that the WindowsIdentity name would always be the name of
the currently logged on user.

Please tell me if I am right (or correct me if I'm wrong ! ), and if
so, then Environment.Username would not be such a good method of
getting this information, after all.

Thanks,

Cerebrus.

Hi,

Yes, Environment.Username makes internally a call to the Win32 API function
GetUserName and according to the docs
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/getusername.asp)
it retrieves the user associated with the current thread. So, in most cases
it will do the trick but if you are calling it from a Windows service it
won´t do the trick, although it doesn´t make much sense to do it from a
Windows service (by definition)...
