In thin client deployments, this variable lets you control which events your program receives, giving you more control over the volume of network traffic. It must be set in the configuration file and cannot be changed programmatically with the SET verb. It contains the numeric value of a single .NET or ActiveX event type or a list of .NET or ActiveX event types separated by non-numeric characters like spaces or commas. Whether your program receives these events depends on the value of TC_EXCLUDE_EVENT_LIST. If its value is 0, then your program receives the events listed in TC_AX_EVENT_LIST. If TC_EXCLUDE_EVENT_LIST is set to 1, then the events listed in TC_AX_EVENT_LIST are not sent to your program.
