K3需要对老单进行二次开发，老单的二次开发比较麻烦，这里整理一下老单序时簿上添加按钮的二次开发示例。
--以下SQL脚本
--获取 MENU ID
select FID,FmenuID,FName from iclisttemplate where Fname LIKE '%生产领料%' --(FID=11,FmenuID=82)
--增加元数据按钮
select * from t_MenuToolBar order by FToolID
Delete From t_MenuToolBar Where FToolID = '10005'
insert into t_MenuToolBar (FToolID,FName,FCaption,FCaption_CHT,FCaption_EN,FImageName,FToolTip,FToolTip_CHT,FToolTip_EN,FControlType,FVisible,FEnable,FChecked,FShortCut,FCBList,FCBList_CHT,FCBList_EN,FCBStyle,FCBWidth,FIndex,FToolCaption,FToolCaption_CHT,FToolCaption_EN)
values (10005,'HMPrint','汇总打印','汇总打印','Print(HM)','6','汇总打印','汇总打印','Print(HM)',0,0,1,0,0,'','','',0,0,0,'汇总打印','汇总打印','Print(HM)')
--将上面的按钮插入到工具栏
select * from t_BandToolMapping where fid=82 and fbandid=53 order by findex
Delete From t_BandToolMapping where FToolID = 10005 and FID = 82
insert into t_BandToolMapping (FID,FBandID,FToolID,FSubBandID,FIndex,FComName,FBeginGroup)
values (82,53,10005,0,77,'|zh_ActiveX_XYL.List_iTool',1) --插件名称.类模块名称
--在[生产领料单]序时薄显示按钮(如果里面有"|V",则只能在后面加菜单项)
select * from IclistTemplate where FID =11
Update IclistTemplate
set FLogicStr=FLogicStr+ Case When Right(FLogicStr,1)='|' then 'V:HMPrint' else '|V:HMPrint' end
where FID =11 and FLogicStr not like '%HMPrint%'
--以下插件代码：
Public Sub MainFunction(ByVal sKey As String, oList As Object, ByRef bCancel As Boolean)
Dim i As Long
Dim FInterID As Long
Dim FEntryID As Long
If sKey = "HMPrint" Then
oList.MultiSelect = 2
For i = 1 To oList.ListSelectBillinfo.Size
FInterID = oList.ListSelectBillinfo(i)("FInterID")
FEntryID = oList.ListSelectBillinfo(i)("FEntryID")
Next
End If
end sub
