As many of you know, event receivers are a great way to hook into various SharePoint events.  These can apply to Feature events such as FeatureActivated, List events such as FieldAdded, and many others.  The most common set of receivers used, however…

当你利用这些事件时,就很快会发现存在前(同步)后(异步)两种事件.其方法的后缀分别为“ing”(比如,ItemAdding)和“ed”(比如,ItemAdded),分别代表了变更发生前调用和发生后调用.这些都是最基本的东西. 接下来,当你更深入时甚至发现,你可以提取变更前和变更后的状态变化.比如,我们可以挂接到一个文档库的ItemUpdating事件上,来阻止用修改某个特定的字段.其代码大致如下: 1 2 3 4 5 6 7 8 public override void  ItemUpdatin…

这个这个属性是不能获取到中文的意思,他是获取AfterProperties的集合的值. string name=properties.AfterProperties["登录人"].Tostring(): 所以最后的办法是在调式的时候,查看你要获取列名的key的命名就可以了. 将key的命名放到“登陆人”那里.…

简单介绍下状态机工作流,状态机工作流提供了一系列的状态.工作流从初始状态开始,到终止状态结束.两个状态之间定义行为进行过渡.通常情况下,状态机工作流对事件作出反应,事件的发生将会使状态发生改变. 1.新建项目,选择SharePoint解决方案,创建空项目: 2.选择调试站点,部署为场解决方案,如下图: 3.添加新项,选择“Office/SharePoint”下面的“状态机工作流(仅场解决方案)”: 4.选择列表工作流,修改工作流名称为“日常报销”: 5.选择调试时使用的列表,并选择任务列表和历史…

配置文件是Spring的核心,在配置文件中我们可以看到,定义了两个bean,其中一个是对接口实现类的发布,而另一个则是对RMI服务的发布,使用org.springframework.remoting.rmi.RmiServiceExporter类进行封装,其中包括了服务类,服务名,服务接口,服务端口等若干属性,因此我们可以断定,此类应该是发布RMI的关键类. 根据示例,启动Spring中的RMI服务并没有多余的操作,仅仅是开启Spring的环境:读取xml文件,于是我们分析可能是RmiServi…
