Retrieve the name of the user signed in to the network
This topic contains a user-defined function, GetLogonName, that returns the current user name. The GetLogonName function utilizes the GetUserNameA Windows API to retrieve the current user name.
' Access the GetUserNameA function in advapi32.dll and
' call the function GetUserName.
Declare Function GetUserName Lib "advapi32.dll" Alias "GetUserNameA" _
(ByVal lpBuffer As String, nSize As Long) As Long
' Main routine to retrieve user name.
Function GetLogonName() As String
' Dimension variables
Dim lpBuff As String * 255
Dim ret As Long
' Get the user name minus any trailing spaces found in the name.
ret = GetUserName(lpBuff, 255)
If ret > 0 Then
GetLogonName = Left(lpBuff, InStr(lpBuff, Chr(0)) - 1)
Else
GetLogonName = vbNullString
End If
End Function
