--  日期时间查询代码问题
某一列的格式为datetime，现在在窗体中DateTimePicker 输入开始及结束日期，希望将此日期段所有涉及的数据列出，请问以下这个代码应该如何修改
With e.Form.Controls("DateTimePicker5")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "提交时间 >= \'" & .Value.AddDays(-1) & "\'"
End If
End With
With e.Form.Controls("DateTimePicker6")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "提交时间 <= \'" & .Value.AddDays(1) & "\'"
End If
End With

将代码改成这样可以实现，请问还有其它方式吗？
With e.Form.Controls("DateTimePicker5")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "提交时间 >= \'" & .Value & " 00:00 \'"
End If
End With
With e.Form.Controls("DateTimePicker6")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "提交时间 <= \'" & .Value & " 23:59 \'"
End If
End With
