Abstract: This article discussed the R & D environment of Virtual Instrument(VI).Based on the characteristics of VI's development and application,the technique of Mixed Programming with MATLAB and VC was researched,and a method based on this technique to design VIs was put forward.Finally,an example of digital filter analytical instrument demonstrated realization of this method by making full use of VC++ in generating user graphic interfaces and MATLAB in signal processing.

Keywords: Virtual instrument; VC++; MATLAB; Dynamic link library; Digital filter; Analytical instrument
