是按日加载，也是帮助里的。不过帮助里不是按日加载，是按月和产品。我改了一下后按日加载树出来了，不过点“日”的时候不加载。

麻烦帮我再规范一下下面的代码。我的表名是cghd，日期列名是dhrq。不要产品加载，只要按年月日加载就好。谢谢

Dim cmd As New SQLCommand

Dim dt As DataTable

cmd.CommandText = "SELECT DISTINCT Year(日期) As 年, Month(日期) As 月, day(日期) As 日, 产品 From {订单}"

dt = cmd.ExecuteReader()

Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")

trv.BuildTree(dt, "年|月|日|产品")

Dim Value() As String

Dim Filter As String

Dim d1 As Date

Dim d2 As Date

Value = e.Node.FullPath.Split("\")

Select Case e.Node.Level

    Case 0

        Dim y As Integer = value(0)

        d1 = New Date(y,1,1) '取得该年的第一天

        d2 = new Date(y,12,31) '取得该年的最后一天

        Filter = "日期 >= #" & d1 & "# And 日期 <= #" & d2 & "#"

    Case 1

        Dim y As Integer = value(0)

        Dim m As Integer = value(1)

        d1 = New Date(y, m, 1) '取得该月的第一天

        d2 = new Date(y, m, Date.DaysInMonth(y,m)) '取得该月的最后一天

        Filter = "日期 >= #" & d1 & "# And 日期 <= #" & d2 & "#"

    Case 2

        Dim y As Integer = value(0)

        Dim m As Integer = value(1)

        Dim d As Integer = value(2)

        d1 = New Date(y, m, d) '取得该月的第一天

        Filter = "日期 = #" & d1 & "# "

    Case 3

        Dim y As Integer = value(0)

        Dim m As Integer = value(1)

        Dim d As Integer = value(2)

        d1 = New Date(y, m, d) '取得该月的第一天

        Filter = "日期 = #" & d1 & "# And 产品 = '" & Value(3) & "'"

End Select

Tables("订单").Filter = Filter

我的例子不是已经写好给你叻吗.就是按照年月日加载的啊.

感觉后面还带一个“产品”，而且我实在别的表用。那段代码通用吗？估计还得换一下表名和字段名吧？

Dim cmd As New SQLCommand

Dim dt As DataTable

cmd.CommandText = "SELECT DISTINCT Year(dhrq) As 年, Month(dhrq) As 月, day(dhrq) As 日 From {cghd}"

dt = cmd.ExecuteReader()

Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")

trv.BuildTree(dt, "年|月|日")

 

 

Dim Value() As String

Dim Filter As String

Dim d1 As Date

Dim d2 As Date

Value = e.Node.FullPath.Split("\")

Select Case e.Node.Level

    Case 0

        Dim y As Integer = value(0)

        d1 = New Date(y,1,1) 

        d2 = new Date(y,12,31) 

        Filter = "dhrq >= #" & d1 & "# And dhrq <= #" & d2 & "#"

    Case 1

        Dim y As Integer = value(0)

        Dim m As Integer = value(1)

        d1 = New Date(y, m, 1) 

        d2 = new Date(y, m, Date.DaysInMonth(y,m)) 

        Filter = "dhrq >= #" & d1 & "# And dhrq <= #" & d2 & "#"

    Case 2

        Dim y As Integer = value(0)

        Dim m As Integer = value(1)

        Dim d As Integer = value(2)

        d1 = New Date(y, m, d) 

        Filter = "dhrq = #" & d1 & "# "

    End Select

Tables("cghd").Filter = Filter

Microsoft Jet 数据库引擎找不到输入表或查询 '~TMPCLPcghd'。 确定它是否存在，以及它的名称的拼写是否正确。

还是把例子上来，谁知你的表是咋回事。
