主题：老师给价格筛选的代码

老师， 如果给下面的代码加一个某个订单下零件需求， 如何加代码来筛选呢？ 

 

Dim dic As new Dictionary(of String,Integer)
DataTables("零件需求").DataRows.Clear()
For Each dr1 As DataRow In DataTables("生产计划").DataRows
    For Each dr2 As DataRow In DataTables("零件用量").Select("[产品] = '" & dr1("产品") & "'")
        Dim nm As String = dr2("零件")
        Dim vl As Integer = dr1("生产数量") * dr2("用量")
        If dic.ContainsKey(nm) = False
            dic.Add(nm,vl)
        Else
            dic(nm) = dic(nm)+ vl
        End If
    Next
Next
For Each key As String In dic.keys
    Dim dr As DataRow = DataTables("零件需求").AddNew()
    dr("零件") = key
    dr("需求数量") = dic(key)
Next

 呃，没有表结构，谁知道怎么改。

 

 订单表和生产计划和零件用量有什么关系。

此主题相关图片如下：jh001.png

当计划单号为JH001，生成统计， JH002，生成新的统计， 窗口搞个文本款， 可输入计划单号， 不同的计划单号生成不同的统计表

 订单和计划有什么联系？订单号就是计划编号？

请老师忽略订单， 写错了， 应该是计划编号

这个意思？

 

Dim dic As new Dictionary(of String,Integer)
DataTables("零件需求").DataRows.Clear()
For Each dr1 As DataRow In DataTables("生产计划").Select("计划单号 = 'JH001'")
    For Each dr2 As DataRow In DataTables("零件用量").Select("[产品] = '" & dr1("产品") & "'")
        Dim nm As String = dr2("零件")
        Dim vl As Integer = dr1("生产数量") * dr2("用量")
        If dic.ContainsKey(nm) = False
            dic.Add(nm,vl)
        Else
            dic(nm) = dic(nm)+ vl
        End If
    Next
Next
For Each key As String In dic.keys
    Dim dr As DataRow = DataTables("零件需求").AddNew()
    dr("零件") = key
    dr("需求数量") = dic(key)
Next

对，动态的如何写

"计划单号 = '" & e.Form.Controls("TextBox1").Text & "'"， 对吗

Dim dic As new Dictionary(of String,Integer)
DataTables("零件需求").DataRows.Clear()
For Each dr1 As DataRow In DataTables("生产计划").Select("计划单号 = '" & Forms("窗口1").Controls("TextBox1").Text &  "'")
    For Each dr2 As DataRow In DataTables("零件用量").Select("[产品] = '" & dr1("产品") & "'")
        Dim nm As String = dr2("零件")
        Dim vl As Integer = dr1("生产数量") * dr2("用量")
        If dic.ContainsKey(nm) = False
            dic.Add(nm,vl)
        Else
            dic(nm) = dic(nm)+ vl
        End If
    Next
Next
For Each key As String In dic.keys
    Dim dr As DataRow = DataTables("零件需求").AddNew()
    dr("零件") = key
    dr("需求数量") = dic(key)
Next

 回复8楼，对。
