[求助]成绩公式如何写? - 专家坐堂 - Foxtable(狐表) - 新一代数据库软件，完美融合Access、Foxpro、Excel、vb.net之优势，人人都能掌握的快速软件开发工具!

1、

For Each v As String In DataTables("成绩").GetValues("学号")

Dim dr1 As DataRow = DataTables("成绩1").AddNew()

dr1("学号") = v

Dim drs As List(Of DataRow) = DataTables("成绩").Select("学号 = '" & v & "'")

If drs.Count > 0 Then

dr1("姓名") = drs(0)("姓名")

For Each dr2 As DataRow In drs

dr1(dr2("课程")) = dr2("成绩")

End If

MainTable = Tables("成绩1")

2、和1楼项目一样，先创建好表

Dim dt As DataTable = DataTables("成绩")

Dim Result As DialogResult

Result = MessageBox.Show("确定要导入吗?", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question)

If Result = DialogResult.Yes Then

Dim dlg As New OpenFileDialog

dlg.Filter = "Excel文件|*.xls"

dlg.MultiSelect = True '允许选择多个文件

If dlg.ShowDialog =DialogResult.OK Then

Dim Book As New XLS.Book(dlg.FileName)

Dim Sheet As XLS.Sheet = Book.Sheets("Sheet1")

dt.ResumeRedraw()

dt.StopRedraw()

'systemready = False

Dim nms As New Dictionary(Of String, Integer)

Dim dic As new Dictionary(Of DataRow, Integer)

Dim ls As new List(Of Integer)

For c As Integer = 0 To sheet.Cols.Count - 1

If dt.DataCols.Contains(sheet(0,c).Text.replace(" ", "")) Then

nms.Add(sheet(0,c).Text.replace(" ", ""), c)

End If

For n As Integer = 1 To Sheet.Rows.Count -1

Dim sfzhm As String = sheet(n,nms("buser")).Text

Dim bid As String = sheet(n,nms("bid")).Text

If sfzhm = "" Then Continue For

Dim dr As DataRow = dt.Find("buser = '" & sfzhm & "' and bid='" & bid & "'")

If dr Is Nothing Then

ls.add(n)

Else

dic.Add(dr, n)

End If

For Each key As DataRow In dic.Keys

For Each m As String In nms.keys

If dt.DataCols(m).IsBoolean Then

If Sheet(dic(key),nms(m)).Text = "" OrElse Sheet(dic(key),nms(m)).Text = "False" OrElse Sheet(dic(key),nms(m)).Value = 0 Then

key(m) = False

Else

key(m) = True

End If

Else If dt.DataCols(m).Expression > "" Then

'表达式列

Else If dt.DataCols(m).IsNumeric Then

key(m) = val(Sheet(dic(key),nms(m)).Value)

Else If dt.DataCols(m).IsDate Then

Dim d As Date

If Date.TryParse(Sheet(dic(key),nms(m)).Value, d)

key(m) = d

End If

Else

key(m) = Sheet(dic(key),nms(m)).Value

End If

For Each l As Integer In ls

Dim ndr As DataRow = dt.AddNew

For Each m As String In nms.keys

If dt.DataCols(m).IsBoolean Then

If Sheet(l,nms(m)).Text = "" OrElse Sheet(l,nms(m)).Text = "False" OrElse Sheet(l,nms(m)).Value = 0 Then

ndr (m) = False

Else

ndr (m) = True

End If

Else If dt.DataCols(m).Expression > "" Then

'表达式列

Else If dt.DataCols(m).IsNumeric Then

ndr (m) = val(Sheet(l,nms(m)).Value)

Else If dt.DataCols(m).IsDate Then

Dim d As Date

If Date.TryParse(Sheet(l,nms(m)).Value, d)

ndr (m) = d

End If

Else

ndr (m) = Sheet(l,nms(m)).Value

End If

dt.ResumeRedraw()

'systemready = True

End If
