Sort list items of a TListView with integer values as captions

Problem/Question/Abstract:

I have an integer value as ListItem caption (using InttoStr). I would like to sort according to the Integer value of these captions. Any Ideas?

Answer:

function Cussort(Item1, Item2: TListItem; lParamSort: Integer): Integer; stdcall;
var
  I1, I2: Integer;
begin
  I1 := StrToIntDef(Item1.Caption, -1);
  I2 := StrToIntDef(Item2.Caption, -1);
  if I1 > I2 then
    Result := 1
  else if I2 < I1 then
    Result := -1
  else
    Result := 0;
end;

MyListView.CustomSort(@Cussort, 0);
