Abstract: A network packet detecting control was designed and realized based on ActiveX technique. By using this control, applications can capture and deal with network packet based on users command in all kinds of programming environments. The control provides programmer a unified interface to develop network applications which need capturing packet. It brings users great convenience.

Key words: ActiveX, Winpcap, call-back function
