C/C++使用命令参数介绍

我们从写第一个HelloWorld程序时，就开始使用main函数。后来学到Windows编程，又开始使用WinMain函数。我们都知道每个程序都得有个主函数入口。今天就简单介绍一下我们使用主函数时给它传入命令参数。很早以前就想写了，但是一直没有找到合适的地方。今天碰到项目中的一个问题，便想起了这块儿。。我们通常写控制台main都没有带参数，因为我们很少用到。这个命令参数的功能呢就会涉及到里面的参数。可以这样定义：intmain(intargc,char*a

使用工具安装，运行，停止，卸载Window服务

WSWinForm.exe介绍WSWinForm.exe是我自己开发的一个实用的小工具，用于将任何EXE程序作为Windows服务运行。也就是说WSWinForm只是其注册程序的服务外壳，这个特性对于我们来说非常实用，我们可以通过它来安装，运行，停止，卸载Windows服务，而不再是通过命令行InstallUtil的方式来安装。资源下载你可以通过本文下载。应用程序源代码如何使用下载完软件以后，我们能干些什么呢？看看这个截图吧：。这里可以看到的操作：1.安装

JavaScript 的性能优化：加载和执行

概览无论当前JavaScript代码是内嵌还是在外链文件中，页面的下载和渲染都必须停下来等待脚本执行完成。JavaScript执行过程耗时越久，浏览器等待响应用户输入的时间就越长。浏览器在下载和执行脚本时出现阻塞的原因在于，脚本可能会改变页面或JavaScript的命名空间，它们对后面页面内容造成影响。一个典型的例子就是在页面中使用document.write()。例如清单1清单1JavaScript代码内嵌示例Sou</span>
