C++编写的屏幕拾色器，拖动鼠标就可以获取屏幕任意一点的的颜色，然后给出16进制和RGB颜色值，并将值存入剪贴板；同时在拖动取色过程中适时显示鼠标位置座标、窗口句柄、窗口类名以及窗口标题，因此，这个程序也可以说成是一个鼠标钩子程序，对研究C++还是有帮助的。,C++ to prepare up color screen, and drag the mouse on the screen can get the color of any point, and then given 16 hexadecimal and RGB color value, and value into the clipboard　At the same time, drag the process of taking timely color display coordinates of the mouse position, window handle, window class name and window title, so this process can also be said as a mouse hook procedure, the study of C++ is helpful.
