How to: Search the Calendar for Appointments Within a Date Range that Contain a Specific Word in the Subject

This topic shows a code sample in Visual Basic for Applications (VBA) that finds appointments in the default calendar that occur strictly within the next thirty days and that contain the word "team" in the subject. The returned results include recurrent appointments.

The FindAppts function in the code sample carries out the search using two different queries, first searching for appointments including recurrent appointments that start and end within the date range, then searching among appointments that meet the date range criteria that have "team" in the subject. The following is an outline of the steps:

  1. FindAppts first defines the time period to query, assigning the start time, myStart, as 12:00am on the current system date, and the end time, myEnd, as thirty days after the start time.

  2. It obtains all the items in the default calendar folder.

  3. To include all appointment items strictly within the date range including recurrent appointments, it sets Items.IncludeRecurrences to True and then sorts the items by the AppointmentItem.Start property.

  4. It builds the first query for all appointments that begin on or after myStart, and end on or before myEnd. This query is a Jet query.

  5. It applies the query to items in the default calendar folder, using the Items.Restrict method.

  6. It builds the second query for the appointment subject containing the word "team". It uses the like keyword for substring matching in a DAV Searching and Locating (DASL) query.

  7. It applies the second query to the set of appointments that meet the date range criteria, returned from the first query.

  8. It sorts and prints the start time of all the final returned appointments.

Note that if you want to include appointment items that overlap and do not fall strictly within the specific date range, you should change the first query to one that have appointments begin on or before myEnd, and end on or after myStart.
