I am working with a Word Macro.  In the  macro there are calls to
GetTempPathA API function.  A client has XP and Word 2000 and the return
value of this call is 0 with  no dll error number.  So far  this is the only
client that has this  problem.  Here is the code for the call:
Private Declare Function GetTempDir Lib "kernel32" Alias "GetTempPathA"
(ByVal nBufferLength As Long, _
   ByVal lpBuffer As String) As Long

Const MAX_PATH = 260
  Dim lReturnVal As Long
  Dim sTempDir As String * MAX_PATH
  Dim lLastDllError As Long
  Dim errDesc As String

  On Error GoTo Handle_Error

   lReturnVal = GetTempDir(MAX_PATH, sTempDir)
   If lReturnVal = 0 Then   'error
      lLastDllError = Err.LastDllError

I work with another program that is written in Visual Basic and makes the
same call to get the temporary directory and writes a file in the directory.  
The Word macro now needs to read this file, so I know the API calls are
working for VB but not for VBA.

Does anybody have an idea of what might be the problem?
