摘要：

针对Lab VIEW在高速数据采集系统虚拟仪器软件设计时存在代码执行速度慢、操作不灵活和底层控制不方便等不足,分析了ActiveX控件的特点及其优势,提出了以ActiveX控件为基本元素构筑虚拟仪器软件的方法。最后以一个常用的波形显示控件的设计为实例,详尽介绍了如何用ActiveX控制技术设计满足用户特定要求的图形元素。实践证明,由ActiveX控件构筑的虚拟仪器软件具有形象、逼真的效果且具有更强的灵活性和更快的代码执行速度。

Abstract: The development software LABVIEW has the deficiencies such as slower code execution speed, inflexible operation and inflexibility in basis control when it is used in Virtual Instrument(VI)software design.A new method of building VI software based on ActiveX controls is presented after the character and predominance of the ActiveX Control is analyzed.Taking the design of GRAPH control as an example, it introduces in detail how to design the desired figure element using ActiveX technology.It is proved that the VI software based on ActiveX controls has the effect of visualize and living.Additionally it is more flexible and much faster than conventional method.
