is it possible to filter through subitems based on a criteria (i.e. looking for a bracked datetime string value) and then repopulate the listbox with only found filter values?

There is no built-in filter operation in the current version.
You'd have to programmatically loop through items and remove the items that do not match your filter condition at application level.

Thanks for your suggestion and help.

The below code produces error "Access violation at address 00B4A378" along with a mem leak


I'm sure i'm missing something but not sure what

Thanks again

I'm not sure what you refer to with "below code"?

Fastest to allow us to investigate this is send some sample source project to support via email.
