Private Declare Function apiGetUserName Lib "advapi32.dll" Alias _
    "GetUserNameA" (ByVal lpBuffer As String, nSize As Long) As Long

Function fOSUserName() As String
' Returns the network login name
Dim lngLen As Long, lngX As Long
Dim strUserName As String
    strUserName = String$(254, 0)
    lngLen = 255
    lngX = apiGetUserName(strUserName, lngLen)
    If ( lngX > 0 ) Then
        fOSUserName = Left$(strUserName, lngLen - 1)
    Else
        fOSUserName = vbNullString
    End If
End Function

Is this the best way to do it?

Answer 1

I generally use an environ from within VBA as in the following. I haven't had the problems that Ken mentions as possibilities.

Function UserNameWindows() As String
    UserNameWindows = VBA.Environ("USERNAME") & "@" & VBA.Environ("USERDOMAIN")
End Function
