这个源码比较有意思吧，VB编写的检测鼠标坐标的程序，除了适时显示鼠标坐标外，还可判断鼠标是否离开了图片，同样也给出提示，源码可能使用了Hook的原理的。-The source it more interesting, VB mouse coordinates the preparation of test procedures, in addition to time display the mouse coordinates, it can also determine whether the mouse left the picture, also give tips, source code may use the Hook' s principle.
