Get user name from Windows 2000

If not already done so, create a new module in the Modules section.

Paste this statement into the General Declarations section of the module:
Private Declare Function apiGetUserName Lib "advapi32.dll" Alias _
"GetUserNameA" (ByVal lpBuffer As String, nSize As Long) As Long


Paste this code:

Function fWin2KUserName() As String
Dim lngLength As Long, lngX As Long
Dim strUserName As String
strUserName = String$(254, 0)
lngLength = 255
lngX = apiGetUserName(strUserName, lngLength)
If lngX <> 0 Then
fWin2KUserName = Left$(strUserName, lngLength - 1)
Else
fWin2KUserName = "unknown"
End If
End Function

You can run this function (fWin2KUserName) from anywhere within your application. The best way is to set some variable to be equal to the function:
Dim strUser as String
strUser = fWin2KUserName
