序幕 通常需要在单个IIS实例上托管多个网站,主要在开发环境中,而不是在生产服务器上.我相信它在生产服务器上不是一个首选解决方案,但这至少是一个可能的实现. Web服务器单实例上的多个网站的好处是: 1. 降低硬件成本 2. 减少资源消耗 3. 减少维护 4. 减少物理空间要求除了好处还有局限性.生产服务器通常具有负载平衡器,大体上和外部人员在多个服务器上意味着相同的网站.因此,具有多个网站的单个服务器在其可处理的最大可能负载方面存在限制.如果用户数量很大,可能会出现资源问题. 不仅IIS,Ap…

原文:WPF:如何实现单实例的应用程序(Single Instance) 好吧,这是我将WPF与Windows Forms进行比较的系列文章的第四篇,讨论一下如何实现单实例(single instance) 先来看第一种最简单粗暴的做法: 检测进程名,如果名称一样,则表示程序已经启动了,就不再启动. protected override void OnStartup(StartupEventArgs e) { // Get Reference to the current Process Pro…

上一篇简单的介绍了自定义的Lookup单选的组件,功能为通过引用组件Attribute传递相关的sObject Name,捕捉用户输入的信息,从而实现搜索的功能. 我们做项目的时候,可能要从多个表中获取数据并且选择相关的记录(单选或者多选),也可能要获取不同的变量的值,不一定是Name字段,也有可能在对某个表进行关键字搜索基础上有额外的条件过滤.此公用组件在上述的背景下进行开发,安装地址如下:https://login.salesforce.com/packaging/installPackag…
