从在 Access 中以编程方式打开的 Excel 工作表中删除受保护的视图

Question

我有一个电子表格，我使用 Access 中的 VBA 以编程方式打开：

Set xl = CreateObject("Excel.Application")
With xl
    Call RunASCFormatting(xl, wb, strPath)
    'More code

Sub RunASCFormatting(xl As Excel.Application, wb As Excel.Workbook, strPath As String)
    With xl
        If .ProtectedViewWindows.count > 0 Then
            .ActiveProtectedViewWindow.Edit
        End If
        Set wb = .Workbooks.Open(Trim(strPath) & "ASC.xls", True, False)
        wb.Sheets(1).Rows("1:1").Delete Shift:=xlUp
        .ActiveWorkbook.SaveAs FileName:=Trim(strPath) & "ASC.xlsx" _
        , FileFormat:=xlOpenXMLWorkbook, CreateBackup:=False
    End With
End Sub

我已在 sub 中的“If”语句中添加，因为我希望它会删除“受保护的视图 - 由于信任中心中的文件阻止设置，不建议编辑此文件类型”消息。我想要实现的是去掉“启用编辑”按钮，这样这个宏就可以启用编辑并按计划运行。

目前，代码位于“Set wb”行。实现我所追求的正确方法是什么？

一种可能性是在打开 Excel 工作簿之前以编程方式将宏安全设置更改为最低。操作数据后，重新启用之前的宏安全设置。

这是我在http://www.mrexcel.com/forum/excel-questions/631545-change-trust-center-settings-visual-basic-applications.html找到的一些修改后的代码：

Public Sub MySubroutine()
    Dim lSecurity As Long

    lSecurity = Application.AutomationSecurity
    Application.AutomationSecurity = msoAutomationSecurityLow

    '''''''''''''''''''''
    '   Run code here   '
    '''''''''''''''''''''

    Application.AutomationSecurity = lSecurity
End Sub

作为旁注，VBA 将 Integer 实现为 Long，因此声明 Integer 变量实际上可能会稍微降低性能，因为它必须重新解释 Integer 关键字。当我了解到这一点时，我开始将 Integer 声明为 Long。实际上，我在一些 Microsoft 文档中读到了这一点，但几年前我失去了它的链接。

Sub trusted_locations(path_to_add)

    Const HKEY_CURRENT_USER = &H80000001

    Dim oRegistry
    Dim sDescription        'Description of the Trusted Location
    Dim bAllowSubFolders        'Enable subFolders as Trusted Locations
    Dim bAllowNetworkLocations  'Enable Network Locations as Trusted

    vers = Application.Version

    sParentKey = "Software\Microsoft\Office\" & vers & "\Excel\Security\Trusted Locations"

    iLocCounter = 0
    oRegistry.EnumKey HKEY_CURRENT_USER, sParentKey, arrChildKeys
    For Each sChildKey In arrChildKeys
        oRegistry.GetStringValue HKEY_CURRENT_USER, sParentKey & "\" & sChildKey, "Path", sValue
        If sValue = spath Then bAlreadyExists = True

        If CInt(Mid(sChildKey, 9)) > iLocCounter Then
                iLocCounter = CInt(Mid(sChildKey, 9))

   bAllowNetworkLocations = True
   If bAllowNetworkLocations Then

   End If

    If bAlreadyExists = False Then
        sNewKey = sParentKey & "\Location" & CStr(iLocCounter + 1)

        oRegistry.CreateKey HKEY_CURRENT_USER, sNewKey
        oRegistry.SetStringValue HKEY_CURRENT_USER, sNewKey, "Path", path_to_be_added
        oRegistry.SetStringValue HKEY_CURRENT_USER, sNewKey, "Description", description_of_path

        If bAllowSubFolders Then
            oRegistry.SetDWORDValue HKEY_CURRENT_USER, sNewKey, "AllowSubFolders", 1
        End If
    End If
End Sub

您可以尝试在信任中心关闭受保护的视图设置

http://office.microsoft.com/en-us/excel-help/what-is-protected-view-HA010355931.aspx#BM5

http://www.howtogeek.com/60310/enable-editing-for-all-office-2010-documents-by-disabling-protected-view/

这可能有害。

此外，您应该设置受信任的位置。

子文件块（值 As Long） 常量 HKEY_CURRENT_USER = &H80000001

Dim oRegistry
Dim sParentKey
Dim vers As Variant
Dim item As String: item = filetype_to_change_fileblock

'确定用户的 MyDocuments 文件夹的位置/路径 '****************************************************** ****************************** 设置 oRegistry = GetObject("winmgmts:\.\root\default:StdRegProv")

vers = Application.Version

sParentKey = "Software\Microsoft\Office\" & vers & "\Excel\Security\FileBlock"

oRegistry.SetDWORDValue HKEY_CURRENT_USER, sParentKey, item, value


End Sub
