.Net has a nice support for these things, examples are in C# but VB Net translation is obvious, let’s see it:
User Name
The simplest way to retrieve username in .NET is to use System.Environment namespace:
string sUserName; sUserName = System.Environment.UserName();
Note that user name retrieved is the user that launch process.
Domain Name
Again with System.Environment namespace:
string sUserDomainName; sUserDomainName = System.Environment.UserDomainName();
Note that this domain name retrieved is the domain of user that launch process.
Computer Name
There are may ways, with System.Environment namespace:
string sMachineName; sMachineName = System.Environment.MachineName();
But we also use System.Net.Dns namespace and retrieve computer name from DNS in may ways:
string sComputerName; sComputerName = System.Net.Dns.GetHostName();
string sComputerName;
sComputerName = System.Net.Dns.GetHostByName("localhost").HostName;
Of course your network services must be active to call System.Net.Dns namespace.
