HiTime VBX/OCX is a high resolution timer. You use this control just like the Default Timer control that comes with Visual Basic. Visual Basic's Timer control can only fire an event every 55 milliseconds (18.2 times per second). HiTime can fire events at a much higher rate. How high depends on the speed of your machine. 486DX2/66's can handle more than 500 ticks per second. 66mhz Pentiums can handle 1000 ticks per second.
