Perform Periodic Updates
If the data in a web query changes frequently, you may want to have Excel automatically update the information periodically. Since web queries already run asynchronously in the background, getting them to update periodically is a simple matter of setting a property:
Set qt = ws.QueryTables("Real-Time Quote")
qt.RefreshPeriod = 1Now, the query will update every minute. To turn off the background query, set the RefreshPeriod to 0 as shown here:
qt.RefreshPeriod = 0
Interestingly, the BackgroundQuery property can be False and you can still perform periodic queries. In that case, the Excel user interface pauses periodically whenever the query is being refreshed.
