9. VBA Tips - Run Code Every Hour, Minute or Second

Nick's picture


In this VBA tip, we will learn how to run a piece of code every hour, minute, second or indeed any time:

  • Suppose you have a live feed coming in for a share price
  • You want to record your own price history for later analysis
  • This tip will show you the code you need for this.

Here's our data:

run-code-every-hour-minute-or-second

So for demonstration purposes, lets look at how to copy over the price every second, and calculate the price change.

Here's a screen shot of the VBA we need:

run-code-every-hour-minute-or-second

Explanation:

  1. TimeToRun is a global variable that we need to record and share between procedures
  2. On opening the sheet, Auto_open is run and that schedules the copy over
  3. Every second, the scheduler runs CopyPriceover
  4. At the end of CopyPriceover, the scheduler is reset to run again the following second
  5. Auto_close unschedules the CopyPriceover sub
  6. We can set the time between runs using TimeValue:
    • Now + TimeValue("00:00:01")  - runs every second
    • Now + TimeValue("00:00:10")  - runs every 10 seconds
    • Now + TimeValue("00:01:00")  - runs every minute
    • Now + TimeValue("01:00:00")  - runs every hour
    • Now + TimeValue("24:00:00")  - runs every day... etc...
