用C实现的DMTF的检测算法。 检测采样频率为8K HZ，16位。 直接在code中写死的，可以在code里修改为其他的。 对标准的双频信号检测还是很准的。 对误差的处理有待改善。 附件里有build出来的文件和一个示例的PCM文件

说明：  C语言趣味程序百例精解，是PDF格式。里面有很多趣味的例子，大大小小的算法都有，可谓是算法的经典。这个是学习算法的好资料，在学习中找到趣味，完全不同于其他资料的算法枯燥无味(C language program 100 cases of sperm interesting solution is in PDF format. There are many interesting examples of both large and small algorithm, the algorithm can be described as classic. This is a learning algorithm is good information, in learning to find interesting information is completely different from other algorithms dull)

C# 实现自动ID，通过存储过程实现员工自动编号，这个在平时的编程中很实用，自动编号使用存储过程来实现，比较高级一些，且数据库需要支持存储过程。 　　con.Open(); 　　SqlCommand cmd = new SqlCommand(); 　　string strSql = "insert into 员工个人信息 values ( + label6.Text + , + this.textBox2.Text + , + this.textBox3.Text + , + this.textBox5.Text + , + this.textBox4.Text + )"; 　　cmd.CommandText = strSql; 　　cmd.Connection = con; 　　cmd.ExecuteNonQuery(); 　　con.Close(); 　　MessageBox.Show("成功添加信息"); 　　this.groupBox1.Enabled = false;
