CListCtrl flickering using EnsureVisible

[Gary]

Hi,

I am experiencing a problem with CListCtrl used in a form view.....
I see that it flickers...........

I am using EnsureVisible to see the last added items and I am using Redraw
items and SetRedraw to avoid flickering but nothing seems to be
working..........

incomingData.SetRedraw( FALSE );
incomingData.InsertItem( mItemsCount, _T("") );
incomingData.SetItemText( mItemsCount, 0, inData );

if (mItemsCount > 15)
{
incomingData.RedrawItems( mItemsCount - 15, mItemsCount );
incomingData.EnsureVisible( mItemsCount - 15, TRUE );
}

mItemsCount++;
incomingData.SetRedraw( TRUE );

Did anyone experience similar behavior ?
If so can you please tell me what else can be done to avoid flickering ?

I haven't had much luck with SetRedraw when it comes to List controls. But
I have had better luck with LockWindowUpdate and UnlockWindowUpdate.

BTW, why are you calling RedrawItems???

Lock and UnLock seem to be better than Redraw but I still see some minor
flickering........

Regarding RedrawItems......I was just trying to redraw portion of
items...but it was not useful...........

What else can I do to reduce the flickering ?.....
also CListCtrl supports upto 100million items right ?

I'm not sure what the maximum capacity of a list control is. But I must say
that if you are planing on displaying a large number of items, you might
want to look into using the the list control in Vitrual mode.
