此主题相关图片如下：本年累计无合计.png

Dim d1 As Date = e.Form.Controls("统计开始日期").Value

Dim d2 As Date = e.Form.Controls("统计结束日期").Value

Dim d3 As Date = e.Form.Controls("年度期初").Value

Dim d4 As Date = e.Form.Controls("上年年末").Value

If d1 = Nothing Or d2 = Nothing Then

MessageBox.Show("起始或结束日期都不能为空!","友情提醒",MessageBoxButtons.OK,MessageBoxIcon.Warning)

End If

Dim g1 As New GroupTableBuilder("入库月计", DataTables("入库")) '客户查询为Click按钮名称

g1.Filter = "日期>=#" & d1 & "# and 日期<=#" & d2 & "#"

Dim bb1 As fxDataSource

g1.Groups.AddDef("名称")

g1.Totals.AddDef("数量","入库_本月小计")

g1.VerticalTotal = True

g1.SubTotal = True

g1.Decimals = 2

g1.FromServer = True

g1.Build()

bb1 = g1.BuildDataSource()

Dim g2 As New GroupTableBuilder("入库累计", DataTables("入库")) '客户查询为Click按钮名称

g2.Filter = "日期>=#" & d3 & "# and 日期<=#" & d2 & "#"

Dim bb2 As fxDataSource

g2.Groups.AddDef("名称")

g2.Totals.AddDef("数量","入库_本年累计")

g2.VerticalTotal = True

g2.SubTotal = True

g2.Decimals = 2

g2.FromServer = True

g2.Build()

bb2 = g2.BuildDataSource()

Dim nms As String() = {"名称","名称"} '指定连接列

bb1.Combine(nms,bb2,nms)

Tables("业务管理_统计表").DataSource = bb1

e.Form.Controls("统计表").Visible = True

代码是这样的,但最后显示出来时,"本年累计"无合计数
