ACC2000: How to Find the Windows and System Paths

• Microsoft Access 2000

SUMMARY

This article describes how to create a Visual Basic for Applications module that uses the 32-bit versions of the GetWindowsDirectory() and GetSystemDirectory() Windows API functions to return the Windows and Windows System directory (folder) paths.

MORE INFORMATION

The following example demonstrates how to use the 32-bit versions of the GetWindowsDirectory() and GetSystemDirectory() Windows API functions:

NOTE: You may have some Microsoft Windows API functions defined in an existing Microsoft Access library; therefore, your declarations may be duplicates. If you receive a duplicate procedure name error message, remove or comment out the declarations statement in your code.

1. Create a module and type the following line in the Declarations section:




Option Compare Database
Option Explicit

Declare Function apiGetWindowsDirectory& Lib "kernel32" Alias _
   "GetWindowsDirectoryA" (ByVal lpBuffer As String, ByVal nSize As Long)
Declare Function apiGetSystemDirectory Lib "kernel32" Alias _
   "GetSystemDirectoryA" (ByVal lpBuffer As String, ByVal nSize _
   As Long) As Long 

2. Type the following procedures:




' This function returns the path to the Windows directory
' as a string.

Function GetWinDir () As String
   Dim lpbuffer As String * 255
   Dim Length as Long
   Length = apiGetWindowsDirectory(lpbuffer, Len(lpbuffer))
   GetWinDir = Left(lpbuffer, Length)
End Function

' This function returns the path to the Windows System folder
' as a string.

Function GetSysDir () As String
   Dim lpbuffer As String * 255
   Dim Length as Long
   Length = apiGetSystemDirectory(lpbuffer, Len(lpbuffer))
   GetSysDir = Left(lpbuffer, Length)
End Function
 

3. To test the GetWinDir() function, type the following line in the Immediate window, and then press ENTER:

   
   ? GetWinDir() 

   Note that the Windows folder path is displayed in the Immediate window.



4. To test the GetSysDir() function, type the following line in the Immediate window, and then press ENTER.

   
   ? GetSysDir() 

   Note that the Windows System folder path is displayed in the Immediate window.
