使用 FindFirst 时出现 DAO RecordSet 错误 3251

Question

当我尝试在我的 DAO RecordSet 上使用“FindFirst”时，我收到 “运行时错误 '3251'：这种类型的对象不支持操作。”。有人可以向我解释我做错了什么，而不是搜索记录。我正在使用的变量正在返回正确的搜索值。

Private Sub ctrSend_Click()
Dim intI As Integer
Dim lst As ListBox
Dim varItem As Variant
Dim rst As DAO.Recordset
Dim rst2 As DAO.Recordset
Dim qtySum As Variant
Dim qtyDiff As Variant
Dim rowMax As Variant
Dim rowUpdate As Variant

Set lst = Me![lstShipping]
Set rst = CurrentDb.OpenRecordset("ShipInv", dbOpenTable)
Set rst2 = CurrentDb.OpenRecordset("Storage", dbOpenTable)
qtySum = 0
rowMax = 0

With lst
    If .ItemsSelected.count = 0 Then Exit Sub
        For Each varItem In .ItemsSelected
            qtySum = qtySum + .Column(3, varItem)
        Next

    If Me.[ctrQtyProd] = qtySum Then
        MsgBox "Qty Selected EQUALS Qty Being Shipped.", vbOKOnly, "Confirmation Message"
    ElseIf Me.[ctrQtyProd] > qtySum Then
        MsgBox "Qty Selected LESS THAN Qty Being Shipped, please select more Inventory.", vbOKOnly, "Confirmation Message"
    Else
        qtyDiff = qtySum - Me.[ctrQtyProd]
        rowMax = lst.Column(3, lst.ItemsSelected.count)
        rowUpdate = rowMax - qtyDiff

        rst2.FindFirst "[BIN] = '" & lst.Column(0, lst.ItemsSelected.count) & "'"
        rst2![QtyProd] = lst.Column(3, lst.ItemsSelected.count)
        rst2.Update
        rst2.Close

        MsgBox "Storage Successfully Updated.", vbOKOnly, "Confirmation Message"
    End If
End With

With lst
    For Each varItem In .ItemsSelected
        rst.AddNew
        rst!Order = Me.[ctrSOrder]
        rst!EntDate = Date
        rst!ShipDate = Me.[ctrSDate]
        rst!BIN = .Column(0, varItem)
        rst!SKU = .Column(1, varItem)
        rst!Lot = .Column(2, varItem)
        rst!QtyProd = rowUpdate
        rst.Update
    Next
End With
rst.Close

Set rst = Nothing
Set rst2 = Nothing
MsgBox "Shipping List Successfully Updated.", vbOKOnly, "Confirmation Message"
End Sub

您是否尝试将记录集作为 dbOpenDynaset（默认没有在 open 语句中指定的枚举）或 dbOpenSnapshot 来打开？ Microsoft MSDN 站点上的文档指定它采用这两个记录集之一。

在满足指定条件的动态集或快照类型 Recordset 对象中找到第一条记录，并使该记录成为当前记录（仅限 Microsoft Access 工作区）。
