当时并不清楚结构和指针的概念，所以代码看上去比较繁琐。。。
但至今还是不太会使用结构，继续努力学习，高手见笑了。。。

嗯，真的是我初中时写的，确切的说是初三上半学期写的，而且是利用国庆长假，没有好好复习，用了一个星期写了这么个东西。。一些代码是参考TC3.0帮助手册中的（包括BIOS键盘控制和硬盘可用空间计算）。。其中MYDOS.exe是我写的一套模仿部分DOS工具的套件，哎，现在也不知道哪里去了，这份源代码也是我好不容易找出来的，从我大哥的电脑里挖出来的，本来要他帮我改改的，后来时间久了也都忘了，现在能够回来真的很开心。。。

我今年刚刚上大一，请多指教。。

其实里面没有很难理解的算法，自己看程序就知道了。。。
一个主要是画图形界面，我就说说如何画3D对话框吧。。画3D框之前我参考了当时win98的窗体，左边和上边两条线是高亮白色然后右下两条边是暗灰色，这样就构成了立体的感觉。。然后填充窗体，填充区域的确定，即窗体的大小减去边框占用的大小，然后设定好颜色，使用bar函数填充，这些函数我都参考了TC3.0帮助手册的用法。。一个地方我当时比较难的便是计算标题的位置，只要计算出标题所占用的长度，将窗体整个长度减去标题长度除以2就行了。。

还有一个自己觉得比较难的就是制作进程条，首先我把文件长度计算出来，因为进程条通常是以100%为极限，所以必须用将文件大小除以100计算出每1%所需要的字节，然后根据进程条的长度计算相应的填充区，不断的刷新填充区的大小，直到100%为止，这里其实有个计算错误的地方，在调试程序的时候发现进程条填充区域会溢出，所以我用了一个很不科学的方法去修正这个错误，即减去一些值。。。。我想以后C语言学得好点了再去修改吧。。。。

还有就是BIOS键盘的键值我是怎么得到的。我使用了TC3.0帮助中对于bioskey()函数提供的一个实例一个个将键测试出来，真的很笨不是吗？由于许多功能我能力有限无法全部用C实现，只好用System()函数执行DOS命令，呵呵，真的很傻，现在看来。。。。

拜我为师不敢当，我自己也只是三角猫功夫，不可以教人的。。。希望大家彼此帮助吧

我是上海的。。。
