Win32汇编实现桌面时钟(有托盘图标)

忙了两三天的空余时间，终于把桌面时钟程序完成了，功能也是比较粗糙的。众所周知的，汇编写程序容易造成代码膨胀，本程序光代码就用了465行，对于我来说也算是不少了……

除了实现一些基本功能外，我还为程序实现了在托盘显示的功能。关于实现该功能，当然是费了不少时间，首先要感谢lczelion，他的理论支持下，让我知道了该如何去调用API，以及注意事项。主要还是windows外壳函数Shell_NotifyIcon和结构体NOTIFYICONDATA <>去配合实现的功能，具体如何调用网上也许有很多，就不去说了。但是还有一点就是如何实现窗口像QQ那样，只有托盘图标而把任务栏窗口隐藏？这是我所碰到的问题：原来CreateWindowEx中有个扩展属性WS_EX_TOOLWINDOW，该属性可以把我的想法实现。

对于最费事的还是如何去画时钟，去使用位图。如何使用DC以及ROP码去实现时钟图案和背景，如何去画时钟的指针和外围的圆点，如何去使用浮点寄存器去精确计算时钟指针的坐标来为我所用……这些都是我所碰到的问题以及学习到得知识。再此又要感谢老罗了~~

唯一一点没有按照我想法去走的就是如何只能让该实例程序只运行一个。由于时间关系，这个以后再去实现。据说要调用API，利用互斥法实现，具体思路和函数都知道了，实现也只是迟早的事情了。

程序中一些基本的语句就没有注释，关键的地方用注释表明了。不明白的地方亦可以把MSDN拿出来查查。下面就把代码贴上去：
