Bug in ListBox.IndexFromPoint ?

[Michael A. Covington]

When capturing a MouseDown event on a ListBox, I want to find out which list
item the mouse is on. So I do this:

int i = listBox1.IndexFromPoint(e.X,e.Y);

A click on a nonexistent item (e.g., a listbox from which everything has
been deleted) gives i=65535 but ListBox.NoMatches = -1.

If I say this:

int i = (int16) listBox1.IndexFromPoint(e.X,e.Y);

then I get -1 for nonexistent items as I should. This is in VS 2005.

Thanks. In fact they're on it:

but I think I'll give them my workaround (with int16).
