Dim dt As DataTable

Dim b As New GroupTableBuilder("统计表1",DataTables("流水账RMB"))

b.Groups.AddDef("交易账户")

b.Groups.AddDef("日期",DateGroupEnum.Year,"年")

b.Groups.AddDef("日期",DateGroupEnum.Month,"月")

b.Totals.AddDef("交易账户",AggregateEnum.Count,"订单数") '根据客户列来统计记录数,也就是订单数

dt = b.Build '参数设置为False,生成一个临时表,不在主界面显示

'然后根据统计表生成目录树

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

trv.BuildTree(dt, "交易账户|年|月")

trv.StopRedraw

For Each nd As WinForm.TreeNode In trv.AllNodes

Dim Product As String = nd.DataRow("交易账户")

Dim Year As Integer = nd.DataRow("年")

Dim Month As Integer = nd.DataRow("月")

Select Case nd.Level

Case 0

nd.Text = nd.text & "(" & nd.DataRow("订单数") & "piao)"

Case 1

nd.Text = nd.text & "年(" & dt.Compute("Sum(订单数)","年 = " & Year) & "piao)"

Case 2

nd.Text = nd.text & "月(" & dt.Compute("Sum(订单数)","年 = " & Year & " And 月 = " & Month) & "piao)"

End Select

trv.Nodes.Insert("显示所有行","显示所有行(" & dt.Compute("Sum(订单数)") & "piao)",0)

trv.ResumeRedraw

Select Case nd.Level

Case 0

nd.Text = nd.text & "(" & dt.Compute("Sum(订单数)","交易账户 = '" & Product & "") & "piao)"

Case 1

nd.Text = nd.text & "年(" & dt.Compute("Sum(订单数)","交易账户 = '" & Product & "' and 年 = " & Year) & "piao)"

Case 2

nd.Text = nd.text & "月(" & dt.Compute("Sum(订单数)","交易账户 = '" & Product & "' and 年 = " & Year & " And 月 = " & Month) & "piao)"

End Select

Case 0

nd.Text = nd.text & "(" & nd.DataRow("订单数") & "piao)"

改成

Case 0

nd.Text = nd.text & "(" & dt.Compute("Sum(订单数)","交易账户 = '" & Product & "'") & "piao)"

.NET Framework 版本：2.0.50727.8669

Foxtable 版本：2016.7.29.1

错误所在事件：窗口,流水账,AfterLoad

详细错误信息：

表达式包含无效的字符串常量: '货代交行9610RMB。

少一个单引号，补上

nd.Text = nd.text & "(" & dt.Compute("Sum(订单数)","交易账户 = '" & Product & "'") & "piao)"

谢谢老师，可以了
