唤醒顺序工作流服务

Question

我需要能够“唤醒”顺序工作流服务 - 这个概念之前在状态机中工作，所以我不明白为什么它在序列中不起作用。下面是工作流程的图片。

此工作流用于编排其他工作流服务。它确实需要永远运行 - 但我们需要能够轻柔地关闭它。以前我在状态机中实现了相同类型的事情，延迟是一次转换的触发器，接收是另一个转换的触发器。只要第一次提到的转换没有运行，我就能够让Receive接收消息并转换到最终状态。正如您所看到的，我想要做的就是将布尔值设置为False，表示While循环应该退出，因此工作流将终止。

请帮助我理解为什么这不起作用。

全部谢谢！

您应该获得一些跟踪数据 - 这将有助于您了解正在发生的事情。见Troubleshooting Workflow Services with diagnostic logging

Answer 2

我已经解决了这个问题。这个问题与相关性有关，我应该知道的更好。每个Receive / Send-Reply序列都有自己的发送 - 应答相关句柄的本地__handle1变量。但是，我试图使用它来关联消息以使用SoftExit唤醒序列。我创建了一个新的关联句柄__liveHandle，我在离开开始序列时初始化，然后在软退出序列中的该句柄上进行关联 - 已解决。

谢谢@RonJacobs！

此WorkFlow与Visual Studio Framework 3.5一起出现。 可以使用Framework 4.0中的Active Library或使用Workflow Console Application来完成类似的活动。

我只是想添加这个，因为很多人说他们不能看到Visual Studio中的顺序工作流程。 虽然我们可以使用它来创建仅使用Visual Studio（没有SharePoint / WSS / MOSS / SP2010或Designer）的工作流程。但它不是一个好的IDEA，因为它需要看看OOB项目的开发工作。 最好的方法应该是使用SPD ..或使用MOSS的工作流功能。

使用VS来创建审批工作流程也很痛苦。 我很快就会创建一个wil paste ..
