## Event Handling

Test Container Automation scripts can contain functions that handle events generated by controls on the form.
Any VBScript Sub whose name is of the form controlname_eventname will automatically handle the eventname event of controlname control. This automatic association is created when the script is loaded. This means that any controls for which the script has event handlers must already exist on the form with the proper name when the script is loaded.
The easiest way to do this is to place all of the desired controls on the form, set each control’s name using the Extended page on its property sheet, and then load the script that contains the event handlers. To avoid repeating these steps, you can then save the session to a file. Loading a session loads all of the controls on the form, and then loads all of the scripts that were saved in that session.
