I'm using TDBPlanner in MultiResource mode. There are over 200 resources and I need to determine what available resources there are for a specified date and time period.
If you refer to checks outside the displayed events in the Planner, sorry, on Planner level there is no built-in function for that.
The Planner is positioned on the day in question. The problem is with a large number of resources it is visually difficult for the user to determine which resources are available for a specified time period.
If this is based on visible day, you'll need to loop through the Planner timeslots and you can use Planner.Items.FindFirst() and check if it returns nil (free slot) for the slots you perform a search for.
