With the DDE Interface of TimeWatcher it is possible to develop add-on programs. In the
download section of this site there is an add-on example program provided.
The communication between the add-on program and TimeWatcher is done by Dynamic Data
Exchange (DDE). DDE is a functionality, which is implemented in all Versions of the
Windows Operating System.
An add-on program, which should get notified of TimeWatcher events, must have 6
controls, which are linked to TimeWatcher with the following settings:
- LinkTopic: TimeWatcher|Tiwa
- Link Items: dde_counter, dde_action, dde_empl, dde_long, dde_double,
dde_text, dde_text2
TimeWatcher reports all the events to the add-on, which are written to the log
Database. When such an event occurs the dde_counter control and the other corresponding
controls are updated. The following events can occur.
| dde_action |
Description |
dde_empl |
