Webservice: 异构系统的粘合剂 工业标准 基于Http-XML ，能穿透防火墙 程序和代码的复用

Webservice: 异构系统的粘合剂 Webservice开发中的问题及技巧 互操作问题：序列化（ Serialize ）和反序列化（ DeSerialize ） 生成您自己的.NET webservice代理

Webservice: 异构系统的粘合剂 Webservice开发中的问题及技巧 您不可以在异构系统之间传递例如java.io.File对象 互操作问题：序列化（ Serialize ）和反序列化（ DeSerialize ） 您不可以在异构系统之间传递例如java.io.File对象 您不可以在异构系统之间传递Java中已经序列化的对象例如：javax.swing.JPanel 推荐传输基本数据类型/数组类型 自定义的Java数据对象需要实现JavaBean规范 注意：SOAP 不是 Corba, RMI, RMI-IIOP, .NET remoting, DCOM(+),或者其他典型的远程对象调用机制。

Webservice: 异构系统的粘合剂 Webservice开发中的问题及技巧 .NET端的webservice消费者/代理 强烈建议在Visual Studio .NET中生成一个独立的项目作为webservice的客户端 易于debug，低耦合性

WebBrowser ActiveX控件：驻留Web内容 WebBrowser控件能够无缝的将B/S应用整合到C/S应用中 .NET Compact Framework支持基本的桌面版的WebBrowser控件功能

WebBrowser ActiveX控件：驻留Web内容 API bug 不被支持的属性/方法/事件……

WebBrowser ActiveX控件：驻留Web内容 API Bug 当使用.NET CF中的WebBrowser控件访问一个新的URL的时候会触发两次Navigated和DocumentCompleted事件 这个Bug不影响基于Windows CE5的PPC和SP，这个问题会在未来版本的CE中修复

WebBrowser ActiveX控件：驻留Web内容 不被支持的属性/方法/事件…… .NET Compact Framework不支持Document属性以及相关的属性、事件，除了DocumentText属性 DocumentText是只写的属性 没有DOM对象，不可以遍历HTML中的elements

WebBrowser ActiveX控件：驻留Web内容 Tricks 获取当前访问页面的HTML内容可以使用HttpWebRequest，HttpWebResponse以及SteamReader得到 WebRequest req = (HttpWebRequest)WebRequest.Creat(url); WebResponse res = (HttpWebResponse)req.GetResponse(); StreamReader reader = new StreamReader(res.GetResponseStream()); String output = reader.ReadToEnd(); reader.Close(); res.Close();
