Xailer & OZ Software

Hello Jose , Ignacio
Something strange happens with the TOptionList:aItems Property.
In the include sample try the following when compiled.
1st- Press the first button to insert 4 new Items in the OptionList.
2nd- Press the other button to delete the 4 inserted Items
As you can see the MsgInfo Box inform us with the correct array (aItems)
length. But when going to delete those 4 inserted items only the 1st and 3rd
items
deleted only.
What happens am i missing something??
Regards
Dionisis

The problem is that in the second pass, there is only 3 items left, and the
second item is the original third one. Let's see each iteration (all items
are named by its original pos):
# items item to delete items left
--- ------ -------------- ---------
1 1,2,3,4 1 2,3,4
2 2,3,4 3 2,4
3 3,4 - 2,4
4 4 - 2,4
The correct way to delete the desired items is doing it in reverse order,
that is: FOR n := Len( :aItems ) TO 1 STEP -1
Or like Jose Luis has just pointed: WHILE Len( :aItems ) > 0 ; and deleting
the first item in each iteration.

Dionisis,
excuse me. The correct iteration map is:
# items item to delete items left
--- ------ -------------- ---------
1 1,2,3,4 1 2,3,4
2 2,3,4 3 2,4
At this point, Len( :aItems ) = 2, and the FOR statement ends.
