主题：导入数据按钮代码求教？

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
    For Each fl As String In dlg.FileNames
        Dim mg As New Merger
        mg.SourcePath = fl
        mg.Format = "Excel"
        mg.SourceTableName = "理论机考表$"
        mg.DataTableName = "理论机考表"
        mg.Merge()
    Next
End If

With DataTables("理论机考表")
    .DataCols("身份证号码").RaiseDataColChanged()
   
End With

 

导入数据时，如有单元格数据发生了变化，不是覆盖导入，而是在原有的行数上增加，这是为什么？

那要怎么改才不变就不动、变则覆盖、没有则增加？

.NET Framework 版本：2.0.50727.3655
Foxtable 版本：2014.11.11.1
错误所在事件：窗口,理论机考,Button2,Click
详细错误信息：
String was not recognized as a valid Boolean.Couldn't store <0> in 是否合格 Column.  Expected type is Boolean.
String was not recognized as a valid Boolean.

Dim Book As New XLS.Book("D:\鉴定表格\理论机考表.xls")
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Tables("理论机考表").StopRedraw()
Dim nms() As String = {"工作单位","县公司","姓名","性别","身份证号码","文化程度","鉴定等级","申报鉴定工种","鉴定批次","申报性质","是否合格","理论考否","考试性质","年月","场次","考场","座位号","考试时间","考试地点","准考证号码","备注","照片"}
For n As Integer = 1 To Sheet.Rows.Count -1
    Dim sfzhm As String = sheet(n,0).Text
    Dim dr As DataRow = DataTables("理论机考表").Find("身份证号码 = '" & sfzhm & "'")
    If dr Is Nothing Then '如果不存在同编号的订单
        dr =  DataTables("理论机考表").AddNew()
    End If
    For m As Integer = 0 To nms.Length - 1
        dr(nms(m)) = Sheet(n,m).Value
    Next
Next
Tables("理论机考表").ResumeRedraw()

这是什么原因报错？

要导入的EXCEL表里的是否合格列是“True”和“False"

我想导入的Excel表不可以放在任何盘里吗？一定得指定放在比如D:\鉴定表格\理论机考表.xls？

谢谢甜版！问题现在代码报错是什么原因？

 

呵呵，上面甜版已经回答了，是逻辑列要先处理一下，因为我是连发的提问，现在我正在组织代码，但总会有这错那错

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("D:\鉴定表格\理论机考表.xls")
    Dim Sheet As XLS.Sheet = Book.Sheets(0)
    Tables("理论机考表").StopRedraw()
    Dim nms() As String = {"工作单位","县公司","姓名","性别","身份证号码","文化程度","鉴定等级","申报鉴定工种","鉴定批次","申报性质","是否合格","理论考否","考试性质","年月","场次","考场","座位号","考试时间","考试地点","准考证号码","备注","照片"}
    For n As Integer = 1 To Sheet.Rows.Count -1
        Dim sfzhm As String = sheet(n,0).Text
        Dim dr As DataRow = DataTables("理论机考表").Find("身份证号码 = '" & sfzhm & "'")
        If dr Is Nothing Then '如果不存在同编号的订单
            dr =  DataTables("理论机考表").AddNew()
        End If
        For m As Integer = 0 To nms.Length - 1
            dr(nms(m)) = Sheet(n,m).Value
            For m As Integer = 0 To nms.Length - 1
                If DataTables("理论机考表").DataCols(nms(m)).IsBoolean Then
                    If Sheet(n,m).Value = 0 Then
                        dr(nms(m)) = False
                    Else
                        dr(nms(m)) = True
                    End If
                Else
                    dr(nms(m)) = Sheet(n,m).Value
                End If
            Next
        Next
    Next
End If
这几种要求的代码写在一起还真是难写，我实在是写不出，版主帮改改看错在哪？

改了这句还是报错！

版主，这准考证号码列又有什么错？

 

Dim dr As DataRow = DataTables("理论机考表").Find("身份证号码 = '" & sfzhm & "' And "准考证号码 = '" & zkzhm & "'")

这样改也不行！
