输入四个点，判断此四点是否可形成一个平行四边形。 程序中描述了一个抽象数据类型Vector2D，表示一个向量。具有（x,y）两个值。其本身具有减另一个向量（minus(Vector2D)），判断自身是否为零向量（iszero()），与另一个向量对应值y,x乘积之差(inner(Vector2D))。由于两个向量平行，则乘积之差x1*y2-x2*y1=0。点A，B，C，D四点组成平行四边形的条件是AB//CD，BC//DA且各个向量皆不为零向量。 首先声明四个向量。向量i获得值的方法是由getPoint(int i)获得。然后根据Vector2D重载后的toString（）函数将各个向量输出查看。最后判断此四点是否可组成平行四边行。

If your application uses MFC in a shared DLL, and your application is in a language other than the operating system s current language, you will need to copy the corresponding localized resources MFC42XXX.DLL from the Microsoft Visual C++ CD-ROM onto the system or system32 directory, and rename it to be MFCLOC.DLL. ("XXX" stands for the language abbreviation. For example, MFC42DEU.DLL contains resources translated to German.) If you don t do this, some of the UI elements of your application will remain in the language of the operating system.

用fpga实现的DA转换器，有说明和源码，VDHL文件。 A PLD Based Delta-Sigma DAC Delta-Sigma modulation is the simple, yet powerful, technique responsible for the extraordinary performance and low cost of today s audio CD players. The simplest Delta-Sigma DAC consists of a Delta-Sigma modulator and a one bit DAC. Since, both of these components can be realized using digital circuits, it is possible to implement a low precision Delta-Sigma DAC using a PLD.
