-- 如何解决代码冲突？
If e.DataCol.Name = "逻辑列名" AndAlso e.DataRow("逻辑列名") = True Then
Dim nma() As String = {"型号","规格","A3","A4"} \'A表数据来源列
Dim nmb() As String = {"型号","规格","B3","B4"} \'B表数据接收列
Dim dr As DataRow = DataTables("表B").AddNew
For i As Integer = 0 To nma.Length - 1
dr(nmb(i)) = e.DataRow(nma(i))
Next
End If
用上面的代码，下面的代码失效，如何解决？
Select Case e.DataCol.name
Case "型号","规格"
Dim xh As String
Dim gg As String
If e.DataCol.Name= "型号" Then
xh = e.NewValue
gg = e.DataRow("规格")
Else
gg = e.NewValue
xh = e.DataRow("型号")
End If
If xh > "" AndAlso gg > "" Then
Dim dr As DataRow = e.DataRow
If e.DataTable.Find("型号 = \'" & xh & "\' And 规格 = \'" & gg & "\'") IsNot Nothing Then
MessageBox.Show("已经存在相同型号和规格的行!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)
e.Cancel = True
End If
End If
End Select
Case "型号","规格"
Dim xh As String
Dim gg As String
If e.DataCol.Name= "型号" Then
xh = e.NewValue
gg = e.DataRow("规格")
Else
gg = e.NewValue
xh = e.DataRow("型号")
End If
If xh > "" AndAlso gg > "" Then
Dim dr As DataRow = e.DataRow
If e.DataTable.Find("型号 = \'" & xh & "\' And 规格 = \'" & gg & "\'") IsNot Nothing Then
MessageBox.Show("已经存在相同型号和规格的行!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)
e.Cancel = True
End If
End If
End Select

测试一下，下面没有作用，在执行后，再执行没提示，如何实现重复提示？
Case "型号","规格"
Dim xh As String
Dim gg As String
If e.DataCol.Name= "型号" Then
xh = e.NewValue
gg = e.DataRow("规格")
Else
gg = e.NewValue
xh = e.DataRow("型号")
End If
If xh > "" AndAlso gg > "" Then
Dim dr As DataRow = e.DataRow
If e.DataTable.Find("型号 = \'" & xh & "\' And 规格 = \'" & gg & "\'") IsNot Nothing Then
MessageBox.Show("已经存在相同型号和规格的行!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information)
e.Cancel = True
End If
End If
End Select
