Excel VBA：获取与FitToPageWide相对应的缩放级别

Question

我正在尝试在Excel中构建一个宏，循环遍历所有工作表，并根据最大的工作表设置缩放级别，使得所有工作表都适合一页，但具有相同的比例（这在打印时是必需的）。

然而我无法确定缩放级别，以确保最大的页面适合一页宽度。

使用 .PageSetup.FitToPagesWide = 1 将工作表宽度设置为适合一页时，.PageSetup.Zoom 属性会自动设置为 FALSE。

将FitToPage属性设置回false之后，缩放级别与适合一页之前的相同。

当手动调整工作表使其适合一页宽度时，Excel会显示对应的缩放级别，但似乎没有办法在VBA中读取此信息。是否有人可以帮我解决这个问题？

我可能误解了你的问题，但为什么不创建一个子程序来调整列的大小，另一个子程序来设置每个页面的打印区域呢？ - Part_Time_Nerd

这篇文章有点老了，但是我遇到了类似的问题，这个问题给了我一个可能的答案。

使用Tom Urtis发布的稍微修改过的代码（https://www.mrexcel.com/forum/excel-questions/67080-page-setup-zoom-property.html），以下代码迭代提取缩放比例，然后设置所有页面的缩放比例。

Option Explicit
#If Win64 Then
    Declare PtrSafe Function LockWindowUpdate Lib "user32" (ByVal hwndLock As Long) As Long
    Declare PtrSafe Function FindWindowA Lib "user32" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
#Else
    Declare Function LockWindowUpdate Lib "user32" (ByVal hwndLock As Long) As Long
    Declare Function FindWindowA Lib "user32" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
#End If
Sub SetSameZoomOnAllWorksheets()
    On Error GoTo failed
    Dim initial_sheet As Worksheet, Sheet As Worksheet, minzoom As Double
    With Application
        'stuff to speed up the process and avoid any visible changes by the user
        .ScreenUpdating = False
        .DisplayStatusBar = False
        .EnableEvents = False
        '.Visible = false 'Uncomment on a really slow document to make people freak out. Make sure to have the on error so that you'll set it to visble again
        ActiveSheet.DisplayPageBreaks = False
    End With
    Set initial_sheet = ThisWorkbook.Worksheets(ActiveSheet.name)
    minzoom = 400 ' max value set by zoom
    'iterate over each sheet
    For Each Sheet In ThisWorkbook.Worksheets
        minzoom = Application.Min(minzoom, GetOnePageZoom(Sheet))
    Next Sheet
    'iterate over each sheet once more and set the zoom to the lowest zoom
    For Each Sheet In ThisWorkbook.Worksheets
        With Sheet
            If .Visible = xlSheetVisible Then
                .Select
                .PageSetup.Zoom = minzoom
            End If
        End With
    Next Sheet
    initial_sheet.Select
failed:
    With Application
        'Change it back so that the user may see any changes, perform calculations and so on
        .ScreenUpdating = True
        .DisplayStatusBar = True
        .EnableEvents = True
        ActiveSheet.DisplayPageBreaks = True
        '.Visible = True 'This one is very important to unmark if you have marked .visible = false at the top
    End With
End Sub
Function GetOnePageZoom(ByRef Sheet As Worksheet) As Double
    With Sheet
        If .Visible = xlSheetVisible Then
            .Select
            'LockWindowUpdate locks the specified window for drawing - https://learn.microsoft.com/en-us/windows/desktop/api/winuser/nf-winuser-lockwindowupdate
            'XLMAIN is the current active window in excel
            LockWindowUpdate FindWindowA("XLMAIN", Application.Caption)
            .PageSetup.FitToPagesWide = 1
            .PageSetup.Zoom = False
            'pre-send keys for next command to specify: On pagesetup Dialog Press P to open the 'Print', then press alt + A to set page setup to adjust (Automatically moves into the zoom field but keeps the value), press enter
            'This changes the pagesetup from 'fitstopageswide = 1' to 'automatic' but keeps the zoom at whatever level it was set to by the fitstopageswide
            SendKeys "P%A~"
            Application.Dialogs(xlDialogPageSetup).Show
            LockWindowUpdate 0
            GetOnePageZoom = .PageSetup.Zoom
            Debug.Print .PageSetup.Zoom
        Else
            GetOnePageZoom = 400
        End If
    End With
End Function
