Virtual Instrument ActiveX Control Development

Focusing on application and development of ActiveX control used in simulation system, this paper introduces the method to achieve the NI virtual instrumentation control and use GL Studio software to generate ActiveX Control in the VC++ development environment. With an example of using GL Studio software, it introduces a method of generating ActiveX control based on the idea of designing NI virtual instrumentation control. It provides a good software support for the expansion of GL Studio software in the field of developing virtual simulation interface. The realization method has good real-time and versatility in an engine test system.
