EV-DO

EVDO(EV-DO)实际上是三个单词的缩写:Evolution(演进)、DataOnly。其全称为:CDMA20001xEV-DO,是CDMA20001x演进(3G)的一条路径的一个阶段。这一路径有两个发展阶段,第一阶段叫1xEV-DO,即“DataOnly”,它可以使运营商利用一个与IS-95或CDMA2000相同频宽的CDMA载频就可实现高达2.4Mbps的前向数据传输速率,已被国际电联ITU接纳为国际3G标准,并已具备商用化条件。第二阶段叫1xEV-DV。1xEV-DV意为“DataandVoice”,它可以在一个CDMA载频上同时支持话音和数据。

    f 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.

    Mod_python is an Apache module that embeds the Python interpreter within the server. With mod_python you can write web-based applications in Python that will run many times faster than traditional CGI and will have access to advanced features such as ability to retain database connections and other data between hits and access to Apache internals. A more detailed description of what mod_python can do is available in this O Reilly article.

    This the fourth edition of the Writing Device Drivers articles. This article will introduce the idea of device stacks and how devices interact with each other. We will use the previously created example device driver to demonstrate this topic. To do this we will introduce the idea of a “filter” driver in which we will create to attach to our own driver’s device stack.

    ASP开发指南,里面的西很不错的哟.This book is for anyone who wants to learn about using .NET for web interface design. Beginner or hobbyist .NET developers can certainly get a good foundation of .NET web interface design by going through this book from cover to cover. However, more seasoned .NET professionals, especially if they tend to steer away from the GUI of their projects, can also pick up a thing or two by focusing on certain chapters that appeal to them. This book is meant to take a reader from the beginning of a project to the completion of the interface design. Along the way, concepts are illustrated to show how the different pieces play together. So, anyone who really wants to understand the concepts presented in this book will be able to do so by reading the entire thing. However, this book should also serve as a good reference after you have read it or, in some cases, in place of reading it.

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.
