概要

本分步指南介绍了如何在 Windows XP 显示上启用 ClearType 以便使字体清晰。 ClearType 通过使屏幕字体的边缘平滑来增强显示。 ClearType 尤其适用于液晶显示 (LCD) 设备，包括平面屏幕监视器和便携式计算机。

如何

昨天升级sp3，发现C盘空间不够，于是把wdk的文档拷到D盘，最后更新完毕后再拷回去。
结果今天发现很多帮助文档打不开了，提示“无法显示microsoft文档资源管理器，因为指定的帮助集合“ms-help://ms.msdnqtr.v80.chs”无效 ”，包括WDK，MSDN等等，出错信息与该提示类似。

于是修复dexplore，卸载wdk都无效，一怒之下删掉help8这个dexplore所在目录，然后从别人那考过来一个，一切ok！

为了试试刚买的t300，随便照了几张。

Error 80048820 is a common problem with MSN Messenger and Windows Live Messenger, here are some ways to solve it.

Symptoms

When you start Messenger, you are unable to sign in, the following message is displayed after the sign in process is interrupted.

“Sorry, we were unable to sign you in to the MSN Messenger at this time. Please try again later.

我们在书写C程序的时候，有时候需要根据结构体成员变量的地址，得到结构体的地址，特别是我们想用C来实现C++的继承特性的时候。
我们对问题的分析如下：

• 输入：一个结构体定义type，这个结构体中某个成员变量的名字member以及它的地址ptr
• 输出：包含此成员变量的结构体的地址

为了便于分析，我们给出一个实例来说明

When installing Visual Studio 2008, you might run into an error dialog that reads,
Error 1330.A file that is required cannot be installed because the cabinet file D:\msdn\cab2.cab has an invalid digitalsignature. This may indicate that the cabinet file is corrupt.
The path and name of the cabinet may be different, but might often be D:\msdn\cab2.cab, where D: refers to your DVD drive. How to workaround this issue
You can try installing the product again, but you may have better luc

半自动内存管理策略

引用计数

引用计数是一种 半自动（semi-automated）的内存管理技术，这表示它需要一些编程支持，但是它不需要您确切知道某一对象何时不再被使用。引用计数机制为您完成内存管理任务。

在引用计数中，所有共享的数据结构都有一个域来包含当前活动“引用”结构的次数。当向一个程序传递一个指向某个数据结构指针时，该程序会将引用计数增

本文将对 Linux™ 程序员可以使用的内存管理技术进行概述，虽然关注的重

本文对中断系统进行了全面的分析与探讨，主要包括中断控制器、中断分类、中断亲和力、中断线程化与 SMP 中的中断迁徙等。首先对中断工作原理进行了简要分析，接着详细探讨了中断亲和力的实现原理，最后对中断线程化与非线程化中断之间的实现机理进行了对比分析。

什么是中断

Linux 内核需要对连接到计算机上的所有硬件设备进行管理，毫无疑问这是它的份内事。如果要管理这些设备，首先得和它们互相通信才行，一般有两种方案可实现这种功能

Using Direct Draw Clippers

Overview

Clippers allow you to restrict which portions of a surface can be blitted to at a particular point of program execution. This is accomplished by specifying one or more rectangles in which blitting can occur, known as a clip list.

Direct Draw Clippers should definitely be used in place of software algorithms that perform clipping, because Direct Draw Clippers will take advantage of video hardwar

Blitting to a Surface Using Direct Draw

Overview

Direct Draw allows you to manipulate surfaces by copying data to it through a block transfer, popularly known as a blit. A block transfer is simply copying one region of memory to another. In the case of Direct Draw, however, both the source and the destination of the blit are Direct Draw surfaces.

Direct Draw allows you to take advantage of video hardware acceleration capabilitie

Direct Draw Surfaces

Overview

A Direct Draw surface is simply a linear block of display memory. Surfaces can be copied, manipulated, and destroyed. This document describes Direct Draw surfaces and how to use them. You should have read Direct Draw Initialization prior to reading this document.

Performance Considerat

Direct Draw Initialization

Overview

Before you can use Direct Draw to manipulate the screen, you must first perform some initialization. This document describes the necessary and optional steps involved in Direct Draw initialization. See a reference for missing information about parameters, return values, etc.

Initialization Steps
