如何使用代码使用密码加密访问？

Question

我创建了一个 Deploy Access 文件，用于部署我的生产 Access 文件。这将表重新链接到生产 SQL 服务器，包括禁用 Shift，添加新版本号....我还需要使用密码加密生产访问文件。这应该使用我的 Deploy Access 文件中的代码来完成，但我找不到执行此操作的方法。有任何想法吗？谢谢。

试试这个功能：

Public Function SetDatabasePassword(strDatabasePath As String, Optional pNewPassword As Variant, Optional pOldPassword As Variant) As String
    On Error GoTo SetDatabasePassword_Error
    DoCmd.Hourglass True
    Const cProvider = "Microsoft.ACE.OLEDB.12.0"
    Dim cnn As ADODB.Connection
    Dim strNewPassword As String
    Dim strOldPassword As String
    Dim strCommand As String
    Dim strResult As String

    ' If a password is not specified (IsMissing), ' the string is "NULL" WITHOUT the brackets
    If IsMissing(pNewPassword) Then
        strNewPassword = "NULL"
    Else
        strNewPassword = "[" & pNewPassword & "]"
    End If
    
    If IsMissing(pOldPassword) Then
        strOldPassword = "NULL"
    Else
        strOldPassword = "[" & pOldPassword & "]"
    End If
    
    strCommand = "ALTER DATABASE PASSWORD " & strNewPassword & " " & strOldPassword & ";"
    
    Set cnn = New ADODB.Connection
    With cnn
        .Mode = adModeShareExclusive
        .Provider = cProvider
        If Not IsMissing(pOldPassword) Then
            .Properties("Jet OLEDB:Database Password") = pOldPassword
        End If
        .Open "Data Source=" & strDatabasePath & ";"
        .Execute strCommand
    End With
    strResult = "Password Set"
ExitProc_:
    On Error Resume Next
    cnn.Close
    Set cnn = Nothing
    SetDatabasePassword = strResult

    DoCmd.Hourglass False
    Exit Function

SetDatabasePassword_Error:
    DoCmd.Hourglass False
    If Err.Number = -2147467259 Then
        strResult = "An error occured"
    ElseIf Err.Number = -2147217843 Then
        strResult = "Invalid password"
    Else
        strResult = Err.Number & " " & Err.Description
    End If
    Resume ExitProc_
    Resume ' use for debugging
End Function
