undo.cpp line 3067 error when scrolling listbox

[vituning]

In my application, I initialize a LV multi-column listbox as empty (Item Names set as an empty string array). Then I start writing to this property (Item Names), and once in a while, when scrolling down in the listbox, LV crashes and I get an 'undo.cpp line 3067' error. Any ideas? I thought it may be an array initialization problem, so I init it now with a string array much larger than what I plan to write to it. I get the same crash.

Make a search with ".cpp" and you will get a lot of answers what to do with such kind of error.

vituning,

Are you scrolling around in the multi-column listbox, then deleting all or most of the contents. The error probably happens when you try to undo this action or when you try and scroll the listbox again? If so, before you delete the data, programmatically scroll the listbox to (0,0) or so that atleast valid data will be shown. This should avoid this error.
