How to Get Current Username in VB.NET

[Samir_1]

This code demonstrates how to retrieve the username of the current windows user in VB.NET

Declare Function GetUserName Lib "advapi32.dll" Alias _

       "GetUserNameA" (ByVal lpBuffer As String, _

       ByRef nSize As Integer) As Integer

 

   Public Function GetUserName() As String

       Dim iReturn As Integer

       Dim userName As String

       userName = New String(CChar(" "), 50)

       iReturn = GetUserName(userName, 50)

       GetUserName = userName.Substring(0, userName.IndexOf(Chr(0)))

   End Function

You possibly will more easily obtain the username through just typing:

CONSOLE.WRITELINE (ENVIRONMENT.USERNAME)

One line of code obtains the current username. No controls, not anything else required, just the reference toward the System Class. Put the line of code within Sub Main () and that is all you necessitate. I hope this will help you to solve your query thank you.

Yes, the Environment.Username usually does an internal call to the Win32 API function GetUserName and as per the documents submitted here - http://msdn.microsoft.com/library/de...etusername.asp, it brings back the user associated with the current thread. So mostly it does the job but if you call it from a Windows Service then it wont work for you.

I will simply add the below code to get username in VB.Net

System.Environment.UserName

It is very simple you know but if you want to use anymore then you can also use the below code:

System.Security.Principal.WindowsIdentity.GetCurre nt().Name

Or else, you can also copy the below code:

Imports System.Security
Imports System.Security.Principal

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