Speed optimization can be carried out from three aspects of actual speed, displaying speed and perceptive speed, while size optimization can be dealt with by means of reducing the number of controls, replacing textbox and picture with label controls, etc.

• 速度优化可从真实速度的优化、示速度的优化及感觉速度的优化三方面进行;对程序大小的优化可采用减少控件数目、标签控件代替文本框、享图片等方法处理。
