这是一个比较简单的有关于进度条控制的类，它在进度框中能够显示文件名和百分比，我想读者肯定在装软件的时候看到过。这个类最重要的功能就是允许在进度条中显示文字，如下：
void setshowtext(bool bshow);
你可以通过这个函数来设置是否能显示文字。设置文字你可以用cwnd::setwindowtext，如果你用函数setshowtext(true)来设置能显示文字，但是你没有用cwnd::setwindowtext来设置要显示的文字是什么，那么该类就会用默认的设置，只显示进度百分比，这点大家还是要注意的。
由于本人是菜鸟级的VC编程手，还没有完全理解其中的内容，也就是说没有看完全部的代码，我希望读者能把它读完，会更有好处。下面是其中的一些函数的功能，请大家笑纳： void SetForeColour(colorref col) 设置进度条中的条的颜色 void SetBkColour(colorref col) 设置进度条的背景色 void SetTextForeColour(colorref col) 当进度条没有覆盖文本时，文本的颜色 void SetTextBkColour(colorref col) 当进度条覆盖文本时，文本的颜色 CORLORREF GetForeColour() 得到进度条中条的颜色 CORLORREF GetBkColour() 得到进度条的背景色 CORLORREF GetTextForeColour() 当进度条没有覆盖文本时，得到文本的颜色 CORLORREF GetTextBkColour() 当进度条覆盖文本时，得到文本的颜色 下面是全部的代码，包括H文件CPP文件
