List view - Add multiple items?

[shteev]

I'm writing a database app in Visual C++ 6, using a listview to display my items; up to about 6,000 of them. I'm finding InsertItem() quite slow. Is there a way I can Insert multiple items into the list with a single command, and then edit them when they are in place?

Good luck

Well, every time you insert an item the control is redrawn, which hogs a bit of performance.

You could prevent this by using the (CWnd) methods LockWindowUpdate and UnlockWindowUpdate.

Ie

mTheListCtrl.LockWindowUpdate();
// Add all items
  .
  .
  
mTheListCtrl.UnlockWindowUpdate();

With that many items you might be interested in the "virtual" list control mechanism using the LVS_OWNERDATA style
