说明：  点阵式液晶显示片 型号：12864 驱动程序(Dot-matrix liquid crystal display film models: 12864 driver)

让窗体在屏幕中央,方便管理就这么回事我就编啊()

说明：  一个显示历史数据曲线的程序源代码，压缩包中包含了历史数据文件和程序源码，在公司里用过很好用。开发环境VC++6.0，绘制曲线用的是MFC的CDC。(Curve of a display of historical data source code, compressed package that contains the historical data files and program source code, used in the company good use. Development Environment VC++6.0, MFC is used to draw curves of the CDC.)

利用directshow在VC6.0环境下完成多路视频采集（本例中实现两路）(Use DirectShow in VC6.0 environment to complete multi-channel video capture (in this case the realization of two-way))

说明：  DDE CLIENT,用于dde方式读区服务器内容(DDE Client for dde reading of server content)

Visual C# .NET编程基础,对于VS用于WEB编程的处学者很有帮助(Visual C#. NET programming basis for VS Department for WEB programming academics helpful)

将BSTR类型转换成CString类型，VC++精选编程学习源码，很好的参考资料。(The BSTR CString type, VC++ select learning programming source code, a good reference.)

本论文以OFDM系统为基础，介绍了OFDM系统的基本原理，以及使用OFDM技术的优势所在，并且展望了今后的无线移动技术的发展前景。在简单介绍OFDM原理的同时，着重阐述了OFDM系统在不同信道环境和不不同实现方式下的误码性能。主要包括了OFDM系统在加性白高斯信道，在加性白高斯信道和多径干扰两种不同信道环境下系统的误码性能，其中后者还研究了系统在有保护间隔与无保护间隔的误码性能比较。在理论分析的基础 (This thesis is based on the OFDM system, the basic principle of the OFDM system, as well as the advantages of using OFDM technology, and future prospects for the development of future wireless and mobile technologies. OFDM principle in brief, focusing on the BER performance of OFDM systems under different channel conditions and different implementations. Including OFDM system in additive white Gaussian channel, additive white Gaussian channel and multipath interference of two different channel environment, the system BER performance, the latter of which also studied the system in a protected interval without guard interval BER performance comparison. The basis of theoretical analysis)

介绍了驱动开发中有关IO例程的相关知识。(Introduction drive the development of relevant knowledge IO routines.)
