使用Qt和OpenGL创建跨平台可视化UI(QT OPENGL viewable UI)

void swap1(int x, int y) //值传递 void swap2(int *px, int *py) //指针传递 void swap3(int &x, int &y) //引用传递 的使用(void swap1(int x, int y) //值传递 void swap2(int*px, int*py) //指针传递 void swap3(int &x, int &y) //引用传递 的使用)

说明：  这是一个数据库访问技术方面的程序，是基于ODBC技术的数据库访问，显示数据库表中的所有记录。(This is a database access technical aspects of the procedure is based on ODBC database access technology, the database shows the table all records.)

说明：  可以让.NET 调用 Java代码的工具，简单的类库比较好用，但是比较复杂的就很难用。(The tools that can make. Net call java code are easy to use, but the more complex ones are difficult to use.)

这是嵌入式的底层代码，请大家赶快下载学习。(This is embedded in the underlying code, please download quickly learn.)
