What I get is that List2 = List1 means that List1 and List2 are then both the same (shared, one, single) List. And List1.Sort(True) is sorting that one (shared) List. Thus magically sorting List2 also, ie rearranging the items in List2 but without making the corresponding rearrangements of List3 a

As unsophisticated hobby programmer I simply use List1.sort(true) for i = list1.size-1 to 1 step -1 if list1.get(i) = list1.get(i-1) then list1.remove(i) next

This allows us to sort lists using all kinds of sophisticated ordering. Attached is an example of sorting "person" records. The fields are: Type Person (Name As String, Age As Int, Status As String) We want to first list the employees, sorted by their names and then sorted by their ages. Public

You can sort by multiple fields by sorting the list multiple times, starting with the inner field and going up. Example: Type Test(FieldA As Int, FieldB As Int, FieldC As Int) Dim List As List List.Initialize For i = 1 To 100 List.Add(CreateTest(Rnd(1, 5), Rnd(1, 5), Rnd(1, 5))) Next List.Sor

link: I'm sorry but I don't think that's the question, boolean vs int; it's if you can sort a list of custom type objects on "field1" AND THEN on "field2" (

Call it DelegatedCode, for example. The ListSort function needs these parameters: the list to sort, a "context" to use with(= the object that has the function AComparer), and the function that compares two items. Then sort the list: Public Sub ListSort(lst As List, AContext As Object, AComparer As

Sorting Lists of user defined types using List.SortType is extremely useful on occasion and can simplify a program's data structures significantly,

You can create an additional field just for sorting and add the three strings to that field.

if you are talking about sorting a list in some pre-determined order, there is such a method in the list object. it uses a sort field. if you're talking about swapping 4 items in a list of 100 items, then a swap sub could handle it. unclear how you make the choices "at will" and how many choices
