Well, this seems a little tricky (if not imposible). I'm tryin to make my DBGrid sort its data by clicking on column's title. The thing is that I'm (sadly) working with Delphi3, I'm not using ADO DataSets and the query gets a lot of rows, thus I can't reopen my TQuery changing the "order by" clause on clicks. Someone has implemented so...

When I'm running my COM Office add-in from within the Delphi 5 IDE (using any of the office applications as the host), breakpoints work fine (when using remote debugging symbols and a properly set output folder), but none of the non-delphi exceptions (like access violations) in my code triggers the IDE to break at that point.
