主题：[求助]修改后台数据

老师，我的这段代码如果要找的行存在的话，不能执行修改，不知错在哪里。请指点。谢谢！

代码写在表A的DataColChanged 中

If e.DataCol.Name = "确认缴费" Then
    If  e.DataRow("确认缴费") = True Then
        Dim nma() As String = {"收费部门","科室单号","开单人","缴费人","缴费方式","记账担保人","确认缴费"} 

        Dim nmb() As String = {"收费部门","科室单号","开单人","缴费人","缴费方式","记账担保人","确认缴费"}
        Dim dh As  DataRow = DataTables("收费登记表").SQLFind("[科室单号] = '" & e.DataRow("科室单号") & "'")
        If dh Is Nothing Then
            Dim dr As DataRow = DataTables("收费登记表").AddNew()
            For i As Integer = 0 To nma.Length - 1
                dr(nmb(i)) = e.DataRow(nma(i))
            Next
        Else
            For i As Integer = 0 To nma.Length - 1
                dh(nmb(i)) = e.DataRow(nma(i))
            Next
        End If
    End If
End If

dh.Save 一下才行。

红袍老师，保存了的，还是不行。

If e.DataCol.Name = "确认缴费" Then
    If  e.DataRow("确认缴费") = True Then
        Dim nma() As String = {"收费部门","科室单号","开单人","缴费人","缴费方式","记账担保人","确认缴费"}
       
        Dim nmb() As String = {"收费部门","科室单号","开单人","缴费人","缴费方式","记账担保人","确认缴费"}
        Dim dh As  DataRow = DataTables("收费登记表").Find("[科室单号] = '" & e.DataRow("科室单号") & "'")
        If dh Is Nothing Then
            dh = DataTables("收费登记表").SQLFind("[科室单号] = '" & e.DataRow("科室单号") & "'")
            If dh Is Nothing Then
                dh = DataTables("收费登记表").AddNew()
            End If
        End If
        For i As Integer = 0 To nma.Length - 1
            dh(nmb(i)) = e.DataRow(nma(i))
        Next
        dh.save
    End If
End If

谢谢！

红袍老师，如果If  e.DataRow("确认缴费") = false Then 我要删除dh 代码该怎么写。谢谢！

If e.DataCol.Name = "确认缴费" Then     If  e.DataRow("确认缴费") = True Then         Dim nma() As String = {"收费部门","科室单号","开单人","缴费人","缴费方式","记账担保人","确认缴费"}                 Dim nmb() As String = {"收费部门","科室单号","开单人","缴费人","缴费方式","记账担保人","确认缴费"}         Dim dh As  DataRow = DataTables("收费登记表").Find("[科室单号] = '" & e.DataRow("科室单号") & "'"         If dh Is Nothing Then            dh = DataTables("收费登记表").AddNew()         End If         For i As Integer = 0 To nma.Length - 1            dh(nmb(i)) = e.DataRow(nma(i))         Next         dh.save     Else         Dim dd As  DataRow = DataTables("收费登记表").SQLFind("[科室单号] = '" & e.DataRow("科室单号") & "'")         If dd IsNot Nothing Then             dd.Delete         End If      End If  End If

DataTables("收费登记表").DeleteFor("[科室单号] = '" & e.DataRow("科室单号") & "'")

DataTables("收费登记表").SqlDeleteFor("[科室单号] = '" & e.DataRow("科室单号") & "'")

红袍老师，我的删除按钮的chick事件代码执行出错，不知错在哪里。请指点，谢谢！

Dim dr As Row = Tables("登记总表").Current
If dr IsNot Nothing Then
    Dim ts As DialogResult
    ts = messagebox.Show("您确认要删除该病例信息吗?","提示",MessageBoxButtons.YesNo, MessageBoxIcon.Question)
    If ts = DialogResult.Yes Then
        If dr("初审") = True Then
            MessageBox.Show("请先撤销初审,再删除!","提示")
            Return
        ElseIf dr("确认首次接种") = True Then
            MessageBox.Show("请先撤销确认首次接种,再删除!","提示")
            Return
        ElseIf dr("确认注射狂免") = True Then
            MessageBox.Show("请先撤销确认注射狂免,再删除!","提示")
            Return
        ElseIf dr("确认收费") = True Then
            MessageBox.Show("请先撤销确认收费,再删除!","提示")
            Return
        Else
            dr.Delete
        End If
    End If
Else
    MessageBox.Show("没有可以删除的行","提示")
End If

报什么错？

系统出现严重错误，提示：继续还是退出？继续后删除了，但是表没了，一把红叉叉。对了，如果用菜单删除没问题。
