Programming, Coding and Others

想把GMap.Net和SharpMap合在一起，发现坐标系对不上，总是有点误差。仔细google，发现http://www.sharpgis.net/post/2007/07/27/The-Microsoft-Live-Maps-and-Google-Maps-projection.aspx， 自己Create Transform，终于对上了。

推荐一篇文章 http://www.sqlite.com.cn/MySqlite/11/395.Html

在Silverlight中调用WCF服务（不在IIS中，而是自己开了个ServiceHost），总是出现System.Security.SecurityException。网上看看基本上是说加2个文件crossdomain.xml,clientaccesspolicy.xml。但因为不Host在IIS中，所以。。。应该。。。，请看

在程序中用到了IronPython，然后想到是否可以在程序中开启一个Console窗口用于调试，就像ipy.exe一样，只不过需要传入当前程序的一些变量。

用Reflector查看ipy.exe代码，复制了一个PythonConsoleHost.cs到自身代码，然后需要AllocConsole()开启Console窗口（FreeConsole关闭），因为PythonConsoleHost.Run直到Console关闭才返回，所以需要在另外一个进程中Run PythonConsoleHost。

有个小问题，关于Console.Output(Error, Input)的。因为程序中另外用到了PythonEngine，其中又调用了Console的标准输入输出，导致新开的PythonConsoleHost输出出现问题，因此需要host.Runtime.IO.SetOutput(System.Console.OpenStandardOutput(), System.Console.OutputEncoding);

很一般的一本书，泛泛介绍了一下WCF，很多可以不用看。

编码总是一个麻烦的事情。ASP.NET中默认用UTF8, 但FireFox中QueryString用的是gb2312，所以需要在about:config中更改 network.standard-url.encode-query-utf8为true。

目的：系统中有些数据不大会变化，例如人员信息，但又不想EagerLoad，想采用系统内缓存数据。如何控制Proxy的动作？

方法：1. 继承一个IProxyFactoryFactory，生成自定义的IProxyFactory。

public class ProxyFactoryFactory : IProxyFactoryFactory
    {
        public IProxyFactory BuildProxyFactory()
        {
            return new ProxyFactory();
        }

        public IProxyValidator ProxyValidator
        {
            get
            {
                return new DynProxyTypeValidator();
            }
        }
    }

2. 写自定义IProxyFactory

public class ProxyFactory : AbstractProxyFactory
   {
       private static readonly LinFu.DynamicProxy.ProxyFactory factory = new LinFu.DynamicProxy.ProxyFactory();
       protected static readonly ILog log = LogManager.GetLogger(typeof(NHibernate.ByteCode.LinFu.ProxyFactory));

       public override INHibernateProxy GetProxy(object id, ISessionImplementor session)
       {
           INHibernateProxy proxy;
           try
           {
               NHibernate.ByteCode.LinFu.LazyInitializer interceptor = new NHibernate.ByteCode.LinFu.LazyInitializer(this.EntityName, this.PersistentClass, id, this.GetIdentifierMethod, this.SetIdentifierMethod, this.ComponentIdType, session);
               object obj2 = base.IsClassProxy ? factory.CreateProxy(this.PersistentClass, interceptor, this.Interfaces) : factory.CreateProxy(this.Interfaces[0], interceptor, this.Interfaces);
               proxy = (INHibernateProxy)obj2;

               object target = TryGetCachedTarget(this.PersistentClass, id);
               if (target != null)
               {
                   interceptor.SetImplementation(target);
               }
           }
           catch (Exception exception)
           {
               log.Error("Creating a proxy instance failed", exception);
               throw new HibernateException("Creating a proxy instance failed", exception);
           }
           return proxy;
       }

       private object TryGetCachedTarget(Type persistentClass, object id)
       {
           //return buffered entity
       }
   }

这里采用LinFu的LazyInitializer，首先尝试读系统缓存，如果没用，用原有LazyInitializer，如果有，则用缓存内内容，然后设置好LazyInitializer的target。
