Syntax
TriggerControl()Return Value

Description
Within a Dialog statement's handler procedure, the TriggerControl() function returns the control ID of the last control which the user operated.
Each control in a dialog box can have its own dedicated handler procedure; alternately, one procedure can act as the handler for two or more controls. A procedure which handles multiple controls can use the TriggerControl() function to detect which control the user clicked.
Error Conditions
ERR_INVALID_TRIG_CONTROL (843) error is generated if the TriggerControl() function is called when no dialog box is active.
