VBA Retrieve the name of the user associated with logged username

Question

I want to get the full name of the user (logged in already) in VBA. This code I found online would do getting the username:

UserName = Environ(\"USERNAME\")

How To Call NetUserGetInfo from Visual Basic

(From Microsoft Knowledge Base, article ID 151774)

The NetUserGetInfo function is a Unicode-only Windows NT API. The last parameter of this function is a pointer to a pointer to a structure whose members contain DWORD data and pointers to Unicode strings. In order to call this function correctly from a Visual Basic application, you need to de-reference the pointer returned by the function and then you need to convert the Visual Basic string to a Unicode string and vice versa. This article illustrates these techniques in an example that calls NetUserGetInfo to retrieve a USER_INFO_3 structure from a Visual Basic application.

The example below uses the Win32 RtlMoveMemory function to de-reference the pointer returned by the NetUserGetInfo call.

Step-by-Step Example

1. Start Visual Basic. If Visual Basic is already running, from the File menu, choose New Project. Form1 is created by default.
2. Add a Command button, Command1, to Form1.
3. Add the following code to the General Declarations section of Form1:

' definitions not specifically declared in the article:

' the servername and username params can also be declared as Longs,
' and passed Unicode memory addresses with the StrPtr function.
Private Declare Function NetUserGetInfo Lib "netapi32" _
                              (ByVal servername As String, _
                              ByVal username As String, _
                              ByVal level As Long, _
                              bufptr As Long) As Long

Const NERR_Success = 0

Private Declare Sub MoveMemory Lib "kernel32" Alias _
      "RtlMoveMemory" (pDest As Any, pSource As Any, ByVal dwLength As Long)

Private Declare Function lstrlenW Lib "kernel32" (lpString As Any) As Long

' Converts a Unicode string to an ANSI string
' Specify -1 for cchWideChar and 0 for cchMultiByte to return string length.
Private Declare Function WideCharToMultiByte Lib "kernel32" _
                           (ByVal codepage As Long, _
                           ByVal dwFlags As Long, _
                           lpWideCharStr As Any, _
                           ByVal cchWideChar As Long, _
                           lpMultiByteStr As Any, _
                           ByVal cchMultiByte As Long, _
                           ByVal lpDefaultChar As String, _
                           ByVal lpUsedDefaultChar As Long) As Long

Private Sub Command1_Click()
Dim lpBuf As Long
Dim ui3 As USER_INFO_3

' Replace "Administrator" with a valid Windows NT user name.
If (NetUserGetInfo("", StrConv("Administrator", vbUnicode), 3, _
uf) = NERR_Success) Then
   Call MoveMemory(ui3, ByVal lpBuf, Len(ui3))

   MsgBox GetStrFromPtrW(ui3.usri3_name)

   Call NetApiBufferFree(ByVal lpBuf)
End If

End Sub

' Returns an ANSI string from a pointer to a Unicode string.

Public Function GetStrFromPtrW(lpszW As Long) As String
Dim sRtn As String

sRtn = String$(lstrlenW(ByVal lpszW) * 2, 0)   ' 2 bytes/char

' WideCharToMultiByte also returns Unicode string length
'  sRtn = String$(WideCharToMultiByte(CP_ACP, 0, ByVal lpszW, -1, 0, 0, 0, 0), 0)

Call WideCharToMultiByte(CP_ACP, 0, ByVal lpszW, -1, ByVal sRtn, Len(sRtn), 0, 0)
GetStrFromPtrW = GetStrFromBufferA(sRtn)

End Function

' Returns the string before first null char encountered (if any) from an ANSI string.

Public Function GetStrFromBufferA(sz As String) As String
If InStr(sz, vbNullChar) Then
   GetStrFromBufferA = Left$(sz, InStr(sz, vbNullChar) - 1)
Else
   ' If sz had no null char, the Left$ function
   ' above would return a zero length string ("").
   GetStrFromBufferA = sz
End If
End Function

I would recommend re-factoring this into a module rather than embedding it in the form itself. I've used this successfully in Access in the past.
