利用定时器实现定时采集在vb中，可利用定时器的interval属性设置每秒钟采集的次数，把采集段程序放在定时器的timer事件中来实现数据采集。对于一般计算机来讲，由于受系统硬件能力的限制，定时器每秒钟最多只能产生18个事件，若时间间隔设置得过小，将达不到预期效果　　应用实例下面给出数据采集软件程序中部分主要源代码-Timer timing acquisition in vb, can take advantage of the acquisition of the number of times per second the timer interval property is set, the data acquisition program on the acquisition interval timer the timer event. For general computer terms, due to the capacity constraints of the system hardware timer per second can only produce 18 events, if the interval is set too small, the data acquisition software program will not reach the expected effect of application examples given below in some of the main source code
