Adds an idle handler function to the end of the list of idle event handlers called when Visual FoxPro is waiting for user input or for an event to time out.
Syntax
unsigned int _ActivateIdle(FPFI handler)
FPFI handler /* Event handler. */
Remarks
_ActivateIdle( ) returns an integer identifier for this routine. Use the identifier to remove the idle event handler from the idle loop with _DeActivateIdle( ).
