请问“点燃一支烟”老师的《将表中的某条记录进行单个导出》代码

请问“点燃一支烟”老师，在你的《[示例]将表中的某条记录进行单个导出》文章中，有些代码，不大理解，希望给我解答，另外，窗体上List1,list2应该是组合框呀，怎么是列表框呢？

SELECT MSysObjects.Name, MSysObjects.ParentId, MSysObjects.Flags FROM MSysObjects WHERE (((MSysObjects.Name)<>"Temp") And ((MSysObjects.ParentId)=251658241) And ((MSysObjects.Flags)=0));

还有这一句代码，难理解：rs = "SELECT " & list2 & ", Count(" & list2 & ") AS CouList FROM " & list1 & " GROUP BY " & list2

不好意思，本人基础差，还有下面一段不懂，8，10 To 12又是什么意思？

Select Case tpyedh

Case 8

CurrentDb.Execute "SELECT " & Me.list1 & ".* INTO  生成表  FROM " & Me.list1 & " WHERE (((" & Me.list1 & "." & Me.list2 & ")=#" & Me.lsh & "#))"

Case 10 To 12

CurrentDb.Execute "SELECT " & Me.list1 & ".* INTO  生成表  FROM " & Me.list1 & " WHERE (((" & Me.list1 & "." & Me.list2 & ")='" & Me.lsh & "'))"

Case Else

CurrentDb.Execute "SELECT " & Me.list1 & ".* INTO  生成表  FROM " & Me.list1 & " WHERE (((" & Me.list1 & "." & Me.list2 & ")=" & Me.lsh & "))"

End Select
