主题：求助：如何一键实现帅选本月数据

在表一中有一列是日期，菜单中有两个按键，怎么通过按按键1实现表一中的数据全为本月数据，按键2实现显示所有数据

按时段筛选数据
我们经常需要筛选某个时段的数据，下面列出了各种情况的筛选代码给大家参考。

筛选指定年份数据
例如筛选2011年的订单：
Dim y As Integer = 2011 '指定年份
Dim dt1 As New Date(y, 1, 1)
Dim dt2 As New Date(y, 12, 1)
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter

筛选指定月份数据
例如筛选2011年6月份的订单：
Dim y As Integer = 2011 '指定年份
Dim m As Integer = 6 '指定月份
Dim dt1 As New Date(y, m, 1)
Dim dt2 As New Date(y, m, Date.DaysInMonth(2011,6)) '获取该月的最后一天
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter

筛选指定季度的数据
例如筛选2011年2季度的订单：
Dim y As Integer = 2011 '指定年份
Dim q As Integer = 2 '指定季度
Dim dt1 As New Date(y, 3 * (q - 1) + 1, 1) '获取该季度的第一天
Dim dt2 As New Date(y, 3 * q, Date.DaysInMonth(2011,3 * q)) '获取该季度的最后一天
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter

筛选本年数据
例如筛选本年的订单：
Dim y As Integer = Date.Today.Year
Dim dt1 As New Date(y, 1, 1)
Dim dt2 As New Date(y, 12, 31)
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter

筛选本季度数据
例如筛选本季度的订单：
Dim y As Integer = Date.Today.Year
Dim q As Integer = (Date.Today.Month - 1) \ 3 + 1 '计算现在是第几个季度
Dim dt1 As New Date(y, 3 * (q - 1) + 1, 1) '获取本季度的第一天
Dim dt2 As New Date(y, 3 * q, Date.DaysInMonth(2011,3 * q)) '获取本季度的最后一天
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter

筛选本月数据
例如筛选本月的订单：
Dim y As Integer = Date.Today.Year
Dim m As Integer = Date.Today.Month
Dim dt1 As New Date(y, m, 1)
Dim dt2 As New Date(y, m, Date.DaysInMonth(y, m)) '获取本月的最后一天
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter

筛选本周数据
例如筛选本周的订单：
Dim y As Integer = Date.Today.Year
Dim w As Integer = Date.Today.DayOfWeek '算出今天是星期几
Dim dt1 As Date = Date.Today.AddDays(-w) '获取本周的第一天
Dim dt2 As Date = Date.Today.AddDays(6 - w) '获取本周的最后一天
Dim Filter As String
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
Tables("订单").Filter = Filter

这个太有用了，顶。收藏了

请问高手:如何用按扭一健显示今天日期的所有筛选?

菜单按钮：(初始文本：查询本月)

(注：日期列的日期时间格式Date）

If e.Button.Text = "查询本月" Then
    e.Button.Text = "查询全部"
    Dim dt1 As Date = Format(Date.Today,"y")
    Dim dt2 As Date = Date.Today()
    Dim Filter As String
    Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"
    Tables("订单").Filter = Filter
Else
    e.Button.Text = "查询本月"
    Tables("订单").Filter = ""
End If

查询当天数据：

 

(注：日期列的日期时间格式DateLongTime)

If e.Sender.Text = "查询当日" Then
    e.Sender.Text = "查询全部"
    Dim dt1 As Date = Format(Date.Today,"m")
    Dim dt2 As Date = Date.Now()
    Dim Filter As String
    Filter = "第二列 > = #" & dt1 & "# And 第二列 < = #" & dt2 & "#"
    Tables("表C").Filter = Filter
Else
    e.Sender.Text = "查询当日"
    Tables("表C").Filter = ""
End If 

 

简化版：

本年 Tables("订单").Filter = "日期 > = #" & Date.Now().Year & "-01-01" & "# And 日期 < = #" & Date.Now() & "#"
本月 Tables("订单").Filter = "日期 > = #" & Format(Date.Now(),"y") & "# And 日期 < = #" & Date.Now() & "#"
本日 Tables("订单").Filter = "日期 > = #" & Format(Date.Now(),"m") & "# And 日期 < = #" & Date.Now() & "#"

请问高手：如何一健显示明天的数据？

LZ，请在相应的代码中使用 Tables("订单").Filter = Filter 进行筛选，筛选日期的一般思路是这样：定义要筛选时段的第一天和最后一天，筛选的条件就是：第一天≤筛选日期≤最后一天。

例如筛选2011年6月份的订单：
Dim y As Integer = 2011 '指定年份
Dim m As Integer = 6 '指定月份
Dim dt1 As New Date(y, m, 1)  '获得该月第一天
Dim dt2 As New Date(y, m, Date.DaysInMonth(2011,6)) '获取该月的最后一天
Dim Filter As String     '转化为字符串
Filter = "日期 >= #" & dt1 & "# And 日期 <= #" & dt2 & "#"   '筛选条件为第一天≤筛选日期≤最后一天
Tables("订单").Filter = Filter

 

Dim dt As date = Date.Today.Adddays(1)

Tables("xxx").Filter = "日期 = #" & dt & "#"
