主题：[求助]多列内容，如何排除重复值？

参考代码

 

Dim idx As String = "-1,"
Dim idx_temp As String = ""
Dim pdr As DataRow = Nothing
Dim count As Integer = 0
Dim cs As String = "第一列,第二列,第三列"
For Each dr As DataRow In DataTables("表A").Select("", cs)
   
    Dim flag As Boolean = False
    If pdr IsNot Nothing Then
        For Each c As String In cs.split(",")
            If pdr(c) <> dr(c) Then
                flag = True
                Exit For
            End If
        Next
    End If
    If flag Then
        If count > 1 Then
            idx &= idx_temp
        End If
        count = 1
        idx_temp = ""
    Else
        count += 1
    End If
    idx_temp &= dr("_Identify") & ","
    pdr = dr
Next

If count > 1 Then
    idx &= idx_temp
End If

Tables("表A").filter = "_Identify in (" & idx.trim(",") & ")"

 不能，高级筛选那里，只能单列的。你直接用代码吧，指定列和表即可。

代码没有问题，如果卡机，做个具体的foxtable例子上来看看。

 

 汗，哪里重复啊，品名规格不同啊。

Dim idx As String = "-1,"
Dim pdr As DataRow = Nothing
Dim cs As String = "客户,工序"
Dim flag As Boolean
For Each dr As DataRow In DataTables("询价表").Select("客户 is not null and 工序 is not null", cs)
   
    flag = False
    If pdr IsNot Nothing Then
        For Each c As String In cs.split(",")
            If pdr(c) <> dr(c) Then
                flag = True
                Exit For
            End If
        Next
    End If
    If flag Then
        idx &= pdr("_Identify") & ","
    End If
    pdr = dr
Next
If flag = True Then
    idx &= pdr("_Identify") & ","
End If

Tables("询价表").filter = "_Identify in (" & idx.trim(",") & ") and 客户 is not null and 工序 is not null"

12楼测试，没问题。

你15楼的意思，是不是说少了一个？

 

Dim idx As String = "-1,"
Dim pdr As DataRow = Nothing
Dim cs As String = "客户,工序"
Dim flag As Boolean
For Each dr As DataRow In DataTables("询价表").Select("客户 is not null and 工序 is not null", cs)
    flag = False
    If pdr IsNot Nothing Then
        For Each c As String In cs.split(",")
            If pdr(c) <> dr(c) Then
                flag = True
                Exit For
            End If
        Next
    End If
    If flag Then
        idx &= pdr("_Identify") & ","
    End If
    pdr = dr
Next

If pdr IsNot Nothing Then
    idx &= pdr("_Identify") & ","
End If

Tables("询价表").filter = "_Identify in (" & idx.trim(",") & ") and 客户 is not null and 工序 is not null"
