DefineEvent Function (IbmScreen)
Attachmate.Reflection.Objects.Emulation.IbmHosts Library > IbmScreen Object : DefineEvent Function
The Long value to be used as an identifier for this event. If the value is set to 0 then a value will be automatically assigned.
The event type being defined.
Specifies an interval of time in HH:MM:SS format. The specified event must last this long to satisfy the definition. This argument is only relevant when the value you use for the EventType argument requires a duration. That is, when EventType is DefinedEventType_Silence or DefinedEventType_KeyboardEnabled. The interval begins when the DefineEvent method is executed.
Specifies the string that defines string-oriented events. This argument is only relevant when the value you use for EventType requires a string. That is, when EventType is DefinedEventType_DisplayString, DefinedEventType_TimeOfDay, or DefinedEventType_TimeElapsed.
Specifies the row location for screen events. Use a row number to specify a particular row. When EventType is DefinedEventType_DisplayString, you can use 0 to indicate that the event can occur at any row location. This argument is relevant when EventType is DefinedEventType_CursorEnterField, DefinedEventType_CursorExitField, DefinedEventType_CursorEnterPosition, DefinedEventType_CursorExitPosition, or DefinedEventType_DisplayString.
Specifies the column location for screen events. Use a column number to specify a particular column. When EventType is DefinedEventType_DisplayString, you can use 0 to indicate that the event can occur at any column location. This argument is relevant when EventType is DefinedEventType_CursorEnterField, DefinedEventType_CursorExitField, DefinedEventType_CursorEnterPosition, DefinedEventType_CursorExitPosition, or DefinedEventType_DisplayString.
Defines a specific event.

Parameters

EventNumber
The Long value to be used as an identifier for this event. If the value is set to 0 then a value will be automatically assigned.
EventType
The event type being defined.
Duration
Specifies an interval of time in HH:MM:SS format. The specified event must last this long to satisfy the definition. This argument is only relevant when the value you use for the EventType argument requires a duration. That is, when EventType is DefinedEventType_Silence or DefinedEventType_KeyboardEnabled. The interval begins when the DefineEvent method is executed.
StringParam
Specifies the string that defines string-oriented events. This argument is only relevant when the value you use for EventType requires a string. That is, when EventType is DefinedEventType_DisplayString, DefinedEventType_TimeOfDay, or DefinedEventType_TimeElapsed.
Row
Specifies the row location for screen events. Use a row number to specify a particular row. When EventType is DefinedEventType_DisplayString, you can use 0 to indicate that the event can occur at any row location. This argument is relevant when EventType is DefinedEventType_CursorEnterField, DefinedEventType_CursorExitField, DefinedEventType_CursorEnterPosition, DefinedEventType_CursorExitPosition, or DefinedEventType_DisplayString.
Column
Specifies the column location for screen events. Use a column number to specify a particular column. When EventType is DefinedEventType_DisplayString, you can use 0 to indicate that the event can occur at any column location. This argument is relevant when EventType is DefinedEventType_CursorEnterField, DefinedEventType_CursorExitField, DefinedEventType_CursorEnterPosition, DefinedEventType_CursorExitPosition, or DefinedEventType_DisplayString.

Return Value

Assigned event number
Remarks
Do not try to use VBA DefineEvent method / DefinedEvent event infrastructure and legacy Reflection COM DefineEvent/DefinedEvent infrastructure from within a single active session. This will not work properly as there are differences in functionality between the two and they each utilize the same resources in the underlying connectivity code.
