误差反向传播网络(Back propagation network,简称BP网络)是神经网络中最活跃的方法，且绝大多数采用了三层结构(输入层、一个隐含层和输出层).BP网络是一种非线性映射人工神经网络.本程序用vb实现的bp算法-error back-propagation network (Back propagation network, called BP) neural network is the most active, but the majority adopted a thre

當電腦上跑的應用程式太多,或是 vb 有其它需求, 想知道目前 active window 是哪一個, 用此 vb 程式即可知道.-When the applications run on the computer too much, or vb have other needs, would like to know which one is currently active window, use this vb program can be aware of.
