Sort using 4th element?

ludesroc — Thu, 08 Nov 2012 14:08:19 GMT

Hi,

Is there a way to sort a list using the 4th element?

sort(iList, :Ascending, key := :first)

sort(iList, :Ascending, key := :second)

sort(iList, :Ascending, key := :third)

sort(iList, :Ascending, key := :fourth)

Regards,

Luc

The key parameter takes any function. So to sort the fourth you need to create a function that gets the fourth element.

For example:

sort(iList, :Ascending, key := :fourth)

Function fourth(inList As List) As Any
Return nth(4, inList)
End Function

This will also work in other functions, such as Find

Find(myValue, iList, key:=:fourth)

Thanks Farren! That's exactly was I was looking for!

Now, I can I get this new function to remain in the functions list permanently?

Luc

You're welcome.

To make the function system wide, place it in "C:\Program Files\Autodesk\Inventor ETO Components 2012\Library\UserLib" (adjust for your version of eto)

Also, if you found my solution helpful I would appreciate any kudos you would like to give (Accept as Solution is great too). The two of these are used as a part of the formula to determine a users' "Ranking" and I'd like to increase mine 😛

Great! Thanks again!

Maybe one day I'll be a mentor as well

Farren's answer is correct.

Keep in mind though that the fourth function he wrote , using nth(4, mylist) does not work in the same way that first,second and third do, nth(4,{3,2,1}) returns 1 (i.e. the last element of the list), thirst({3,2}) returns novalue. No difference if your lists have the correct number of entities of course.

The function below will cause it to work the same as :first, :second, and :third.

Function fourth(inList As List) As Any

If length(inlist) < 4 then

Return NoValue

Else
Return nth(4, inList)

End If
End Function
