Okay, I'll admit that the C one was more annoying to write, because programming a Win32 list view directly is a lot of gruntwork.

Therefore, I had to sit down tonight and figure out how you could make a standard Win32 List View update so slowly that a 1541 drive could almost keep up with it. I'm too lazy to reboot into Windows 7 right now.) The way I ended up debugging this involved parallel C and C# apps.

* Fixed scrolling when all items are unselectable * Fixed drag selections (not all intersecting items were always selected) * Fixed sub-item focus rectangle display in Details view when Full Row Select is false * Fixed sub-item background display in Details view when Full Row Select is false * Fixed text highlighting not updating properly after automatic column resizing * Added column unsorting by middle mouse button * Fixed hit test on items in List view * Added overlay image alignments support for columns and items in Detail view * Fixed dragging empty selection when Multi Select=False and user dragged item with Control key pressed * Added sub-item check boxes and radio buttons support * Added support for custom disabled check boxes and radio buttons * Fixed Object Disposed Exception being raised when closing Form right after clicking an item * Fixed Remove Search Highlight to work in item hierarchy * Fixed drawing of group header when the group is focused by keyboard * Fixed disappearing items after scrolling and item reordering in Large Icon view with multi-line items * Added integration with Visual Studio 2013 * Added custom date format support in Better List View Date Time Picker Embedded Control * Added Item Reordered event * Fixed Find Items With Text method call when working with invisible items * Fixed saving form after editing tooltips in Windows Forms Designer * Fixed sorting of items with missing sub-items or Key set to null * Fixed pixel precision bug in column selection * Fixed proper scrolling on combined items using Ensure Visible method * Fixed drawing item selection on Mouse Up in some cases (click directly on text of previously selected item in Details view) * Fixed search highlight in other than Details view * Fixed search highlight on multi-line items * Added Hot Tracking property * Added Smooth Scroll property * Improved responsiveness (optimized control refreshing on control state transitions) * Fixed Better List View Column Header.

However, out of the box, the C app updated much more smoothly and didn't flicker madly.

I'll spare you the debugging details -- which include ILDASM, Win Dbg, Spy , two instances of Visual Studio, and tracepoints in x86 assembly while debugging in mixed mode -- but I managed to figure out what was going on.
