Java

windows下java web（jdk、eclipse、Tomcat）开

一、jdk的安装首先下载jdk-6u26-windows-i586并安装，将其安装到D:\ProgramFiles\Java\jdk1.6.0_26这个文件夹下，默认的是安装到c盘。改成d盘的话，这些文件夹要自己建！！！如果c盘够用，就直接c盘吧，省事。安装完后，点我的电脑-属性-高级-（系统变量）新建，新建一个变量JAVA_HOME，内容是D:\ProgramFiles\Java\jdk1.6.0_26。光弄这还不行，在系统变量里找到Path，点编辑，按

使用宏需要注意的地方

DDK提供了大量的宏。在使用这些宏的时候，要注意一种错误的发生，这就是"侧效"(SideEffect)宏一般由多行组成，如下面的形式，其中的"\"代表换行#definePRINT(msg)KdPrint(("====================\n"));\KdPrint(msg);\KdPrint(("===================\n"));在C语言中规定，for或者if语句块中的内容如果只是一句，可以省略掉{}。如：if(bRet){Fo

FFMPEG视音频编解码零基础学习方法

在CSDN上的这一段日子，接触到了很多同行业的人，尤其是使用FFMPEG进行视音频编解码的人，有的已经是有多年经验的“大神”，有的是刚开始学习的初学者。在和大家探讨的过程中，我忽然发现了一个问题：在“大神”和初学者之间好像有一个不可逾越的鸿沟。“大神”们水平高超，探讨着深奥的问题；而初学者们还停留在入门阶段。究竟是什么原因造成的这种“两极分化”呢？最后，我发现了问题的关键：FFMPEG难度比较大，却没有一个循序渐进，由简单到复杂的教程。现在网上的有关FFM

WPS2012交叉引用技巧，word比wps这点强更新參考

WPS2012交叉引用技巧，word比wps这点强更新參考文献到时生成仅仅有有一条线，好像WPS不能够，word能够，假设谁知道能够补充。^_^1.写论文，參考文献的改动非常麻烦，删除一个，加入一个，就须要改一长串数字。怎么办呢。本人推荐一种简单方法：尾注法。2.光标移到要插入參考文献的地方，菜单中“引用—>脚注和尾注”。把插入的“1”设置为正常，就是选择上下标那个地方。3．确定后在该处就插入了一个上标“1”，而光标自己主动跳到文章最后，前面就是一个上标“
