Hey.

I searched for this on the forum, but couldn't find anything I could really use, so I am asking you:

How do I remove a certain object (of a type I created) from a list after I wrote a compare method for that type?

example :
_____________________
Type car

Field a
Field b
Field c

Method Compare:Int(Other:Object)
If other=Null Return 0
If a=car(other).a Return 0
If a<car(Other).a Then Return 1 Else Return -1
End Method

End Type
_________________________

Let's say there are 10 instances of 'car' stored in 'list'. How do I remove car3:car from that list?

Thanks a lot! I really need your help ;)

method a:

Type car
  Field listLink:TLink
  global list:TList = CreateList()

  Function Add(newCar:car)
    newCar.listLink = list.AddLast(newCar)    
  End Function

  Method RemoveFromList()
    newCar.remove()
  End Method
End Type

Else just do:
carList.remove(car3)

This will loop through the list and delete the car referenced as car3.

If car3 is another object, but shares the same "carID" or "name"or ...
you will have to loop by your own

  for local myCar:car = eachin carList
    if myCar.carID = searchedCar.carID then return myCar 'or carList.remove(myCar);exit
  next

bye
