I fully agree. It is so easy to set up and use it almost seems like it
should be the default. It is certainly not any more trouble than setting up
the normal way. And with the ability to set the number of items "virtually"
as well you can even have the thumb in the scroll bar work as though the
list was actually populated.

Even a couple of hundred items with 2 or 3 sub items will take long enough
that you will have to switch to virtual list mode. If you ask me virtual
list mode should be standard on list control, they should do away with the
normal mode.

I am not using virtual list control.....
I just want to keep on adding possibly millions of items at runtime

Then you're out of luck. My own experience is that virtual list mode is
necessary to keep the list responsive at load AND destroy time as soon as
you have more than a couple thousands items.

See Giovanni's answers for more details. FWIW, "owner-data" = "virtual
list"

Hi,

I would like to know how many items can I insert into a CListCtrl.... ?
I am not using virtual list control.....
I am just using CListCtrl in a form view..........

I just want to keep on adding possibly millions of items at runtime and
save
them to a text file is user wants to...........

I don't want to load those many items..........

InsertItem() takes "int" as parameter index......so CListCtrl should
atleast
support
(-2,147,483,648 to 2,147,483,647) items..........

I just want to make sure I can add as many items as I want at run
time...

Any pointers would be apprciated.

Thanks,
Gary
