Question

我有一个显示40行的Access 2007表单。当我打开它时，我希望当前记录的行显示在显示的40行中的行位置＃5。换句话说，当前行上方应有4行，下方有35行。

MoveUpDown 是我第一次执行此操作，但目前仅在当前记录的行（由 FindFirst 移动）最初显示在行位置时才有效＃ 1到＃5。如何找到当前行的显示位置，相对于显示的行，以及如何更改它？感谢。

Private Sub OpenMyFormTo(sqlWhere As String)
    Dim rs As DAO.Recordset, frm As Form
    DoCmd.Openform "myForm", acNormal
    Set frm = Forms("myForm").Form
    Set rs = frm.RecordsetClone
    If Not (rs.BOF And rs.EOF) Then
        rs.MoveFirst
        rs.FindFirst sqlWhere
        frm.Bookmark = rs.Bookmark
        MoveUpDown frm.Recordset, 5
    End If
End Sub

Private Sub MoveUpDown(rs As DAO.Recordset, RowsToMove As Integer)
    Dim RowsActuallyMoved As Integer, i As Integer
    RowsActuallyMoved = 0
    For i = 1 To RowsToMove
        If Not rs.BOF Then
            rs.MovePrevious
            RowsActuallyMoved = RowsActuallyMoved + 1
        End If
    Next i
    For i = 1 To RowsActuallyMoved
        If Not rs.EOF Then rs.MoveNext
    Next i
End Sub

Answer 1

我不完全确定这是否是你所需要的：
a）直接进入第5条记录，使用： DoCmd.GoToRecord acDataForm, Me.Name, acGoTo, 5
（Me.Name仅在代码位于表单自己的代码模块中时） b）您可以使用查询当前位置 Me.Recordset.AbsolutePosition
奇怪的是，.AbsolutePosition开始计数为0，goto-command为1。

Answer 2

我相信我有一个答案，虽然对我来说似乎很笨拙。此过程找到目标行，向下滚动直到目标行不可见，向上滚动到目标行，通过（偏移）其他行超过目标，然后向下滚动到目标行。结果是目标行显示为（偏移+ 1）可见行。如果行数＆lt;偏移，然后显示为最后一行。

Private Sub DisplayWithOffset(frm As Form, sqlWhere as String, Offset As Integer)

    Dim rs As DAO.Recordset, DetailsHt As Long, RowHt As Long, i As Integer
    Dim RowsVisible As Integer, BookmarkAP As Integer, RowsMoved As Integer

    DetailsHt = frm.InsideHeight _
              - frm.Section(acHeader).Height - frm.Section(acFooter).Height
    RowHt = frm.Section(acDetail).Height
    RowsVisible = IIf(RowHt > 0, DetailsHt Mod RowHt, 0)
    Set rs = frm.Recordset

    If Not (rs.BOF And rs.EOF) Then

        rs.MoveLast
        rs.FindFirst sqlWhere

        BookmarkAP = rs.AbsolutePosition

        RowsMoved = 0
        For i = 1 To RowsVisible
            If rs.AbsolutePosition + 1 < rs.RecordCount Then
                rs.MoveNext
                RowsMoved = RowsMoved + 1
            End If
        Next i

        Do Until rs.AbsolutePosition = BookmarkAP
            rs.MovePrevious
        Loop

        RowsMoved = 0
        For i = 1 To Offset
            If rs.AbsolutePosition > 0 Then
                rs.MovePrevious
                RowsMoved = RowsMoved + 1
            End If
        Next i

        For i = 1 To RowsMoved
            rs.MoveNext
        Next i

    End If

End Sub
