When you use time in a DataWindow, an internal timer event is triggered.  The Timer_Interval attribute of the DataWindow determines the number of milliseconds between internal timer events.  The default is 0 (60,000 or 1 minute).

To change the timer interval attribute:

1. Select DataWindow style on the Design Menu.  The Design DataWindow Style window displays the current timer interval in the Timer Interval box.
2. Enter the number of milliseconds you want to elapse between interval timer events. The default is 0 (60,000 milliseconds or 1 minute).
3. Click OK.  PowerBuilder closes the Design DataWindow Style window and the DataWindow Painter workspace displays.
