# STOP EVENT

`STOP EVENT`

This statement must be used in an event handler. It tells the interpreter that the event that called the event handler must be cancelled.

You can also cancel an event by returning `TRUE` in the event handler. But this statement is clearer.

Note: Only a few events can be cancelled. This is primarily intended to allow you to supersede default keyboard and mouse behavior with your own.

Example

    ' My text box only accepts digits

    PUBLIC SUB MyTextBox_KeyPress()

      IF Instr("0123456789", Key.Text) = 0 THEN
        STOP EVENT
      ENDIF

    END SUB
