Access自動刪除指定的引用,然后再自動重新添加這個引用的通用代碼-判斷了32位及64位Windows和32位Office及64位Office的多種情況

在編寫Access通用平臺或通用開發庫時,或使用第三方控件或鏈接庫時,由于這個開發庫可能經常會更新,由于更新后,開發庫的對象和屬性和方法都有所改變

必須要手工對這個對象重新引用,如果一次兩次還可以手工操作,如果經常更新,就需要寫一個通用刪除和添加引用的函數了


自動重新添加Ocx dll 等控件或鏈接庫的引用(DevlibOcx引用)


Option Compare Database
Option Explicit

Private Const POINTERSIZE As Long = 4
Private Const ZEROPOINTER As Long = 0

Const MAX_LEN = 200    '字符串最大長度
Private Declare Sub apiCopyMemory Lib "kernel32" Alias "RtlMoveMemory" (hpvDest As Any, hpvSource As Any, ByVal cbCopy As Long)

Private Declare Function GetSystemWow64Directory Lib "kernel32" Alias "GetSystemWow64DirectoryA" (ByVal lpBuffer As String, ByVal nSize As Long) As Long

Private Declare Function GetSystemDirectory Lib "kernel32" Alias "GetSystemDirectoryA" (ByVal lpBuffer As String, ByVal nSize As Long) As Long


'Access或Excel VBA或VB6判斷windows系統是32位還是64位
'來判斷系統是32bit還是64bit,主要通過API來實現,先在窗體模塊里申明以下API定義:
Private Declare Function GetProcAddress Lib "kernel32" (ByVal hModule As Long, ByVal lpProcName As String) As Long
Private Declare Function GetModuleHandle Lib "kernel32" Alias "GetModuleHandleA" (ByVal lpModuleName As String) As Long
Private Declare Function GetCurrentProcess Lib "kernel32" () As Long
Private Declare Function IsWow64Process Lib "kernel32" (ByVal hProc As Long, bWow64Process As Boolean) As Long

'然后在窗體或模塊中再建立一個判斷系統是32位還是64位的函數,返回值是布爾值,如果系統是32位,此函數返回值是Flase 如果是64位,返回值是True,函數代碼如下:
Public Function Is64bit() As Boolean
    Dim handle As Long, bolFunc As Boolean
    bolFunc = False
    handle = GetProcAddress(GetModuleHandle("kernel32"), "IsWow64Process")
    If handle > 0 Then
        IsWow64Process GetCurrentProcess(), bolFunc
    End If
    Is64bit = bolFunc
End Function

'獲取64位 windows及32位windows系統 的系統目錄 ,正常都是System32
Public Function GetSystemDir() As String
    Dim sTmp As String * MAX_LEN  '存放結果的固定長度的字符串
    Dim nLength As Long  '字符串的實際長度
    Dim length As Long
 
    Dim strPath As String
     '獲得System目錄
        length = GetSystemDirectory(sTmp, MAX_LEN)
        strPath = Left(sTmp, length)
      GetSystemDir = strPath
End Function
 
'獲取64位windows系統下32位的系統目錄 ,正常是SysWow64
Public Function GetSystemWow64Dir() As String
    Dim sTmp As String * MAX_LEN  '存放結果的固定長度的字符串
    Dim nLength As Long  '字符串的實際長度
    Dim length As Long
 
    Dim strPath As String
     '獲得System目錄
        length = GetSystemWow64Directory(sTmp, MAX_LEN)
        strPath = Left(sTmp, length)
      GetSystemWow64Dir = strPath
      
End Function
