vb6 - Which is better for performance -


recently had write function compares combobox list of items record set database. after finishing work i'm wondering better performance.

solution 1

foreach item in combobox1   foreach record in recordset     if item.id = record["id"]          foundincombo = true         exit     end if    next record    if foundincombo = false        combobox1.removeitem(item)    end if next item

solution 2

foreach item in combobox1   foreach record in recordset     if item.id = record["id"]          foundincombo = true         recordset.remove(record)         exit     end if    next record    if foundincombo = false        combobox1.removeitem(item)    end if next item

this pseudo code of course, , know in modern languages there better ways this, in vb6 , i'm curious if overhead in removing of record record set offsets less amounts of iterations of entire loop.

update: in case learning older language , working in legacy code limited ability change made test based on comments below, , found not of difference first 25 items, once got around 100 started have performance gains removing item.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
