如何模拟七段数码管的显示

Question

请问各位大虾如何通过Windows API函数模拟七段数码管的显示，不是用位图的形式，通过GDI绘图的形式？

Answer 1

VC知识库第53期有一篇这方面的文章 《七段数码显示的数字时钟》http://www.vckbase.com/document/viewdoc/?id=1839 你可以去看看那

Answer 2

我自己写的，用画的方式实现，比较简单，希望能满足你的需求。

}第一贴代码是头文件，第二三四贴代码是实现文件。使用方法：
1，在对话框模板中添加Static Text控件。
2，更改其ID值。
3，在ClassWizard的Member Variables中为其添加CStaticEx类型的Control变量。
4，在对话框类的OnInitDialog()中通过其Control变量调用CStaticEx的颜色设定成员函数。
5，在相应部分调用显示内容设定成员函数。
