From: "Bill Brehm" don't want on 24 Mar 2010 10:55 There are worse things. I'm putting a scrollbar in another project and I just discovered (maybe again, can't recall) that it has a limit of 32767 positions. I'm thinking of using two, one for course and one for fine or even three, but it's not what people are used to seeing. Thanks for the update that even ten years later, CListCtrl hasn't been enhanced. No need to upgrade for that reason.

VS2010 has several advantages if compared to VC6, like better C++ standard compliance, better STL implementation, parallel libraries, etc. Giovanni

FWIW, I tried also a simple WPF test with a listview, and the situation seems to be far worse than native. In fact, even with 100,000 items, the program takes longer to start and then hangs...

According to VS2005 docs, the scroll bar functions support 32-bit position data; it is only the messages WM_xSCROLL that are limited to 16 bits (32767). GetScrollInfo has an example of how to use the 32-bit positions. |
