let's suppose have class this: class myclass(of template) 'some things here end class so far, good. however, things depending on template, like class myclass(of template) 'some things here public sub mymethod 'if template myotherclass ' things 'else ' other things 'end if end sub end class of course, give object , check whether typeof (obj) myotherclass , seems less intuitive me. there way compare 2 classes in vb.net? you compare type class myclass(of template) 'some things here public sub mymethod if gettype(template) gettype(myotherclass) things else other things end if end sub end class but seems bad thing do. point of oo have logic in it's respective class instead of doing this.

i can't seem understand why these 2 queries return different results following task: "find names , grades of students have friends in same grade. return result sorted grade, name within each grade." tables here: https://lagunita.stanford.edu/c4x/db/sql/asset/socialdata.html the first query: select distinct h1.name, h1.grade highschooler h1, friend f, highschooler h2 h1.id = f.id1 , h2.id = f.id2 , h1.grade = h2.grade order h1.grade, h1.name the second query: select name, grade highschooler id not in ( select id1 highschooler h1, friend, highschooler h2 h1.id = friend.id1 , friend.id2 = h2.id , h1.grade <> h2.grade) order grade, name; the second 1 returns expected result, not first one. if cares clarify, thanks. the first query applies 3 filter in query simultaneously data in tables , returns entries matching filters. second query firstly subquery returns rows matching subquery condition , ids not there returned, includes ids h1.id =
