After completing this chapter, you will learn: 1. Learn how each workflow activity is designed to be used to expose your workflow to XML Web services 2. Understand what it takes to host workflows in asp.net 3. See how error (Fault) is handled in workflows based on XML Web services 4. Configure your workflow for xml-based Web services for a variety of situations In the previous chapter, "Invoking Web Services in your workflow", you saw how to invoke an XML Web service using the Invokewebserv

After completing this chapter, you will learn: How the 1.workflow activity is formed 2. The difference between sequential workflow and state machine workflow 3. Create a sequential workflow 4. Create a State machine workflow Activity is the basic unit of workflow processing in WF, and if you break down a business process (or workflow Task), you'll find that it's made up of smaller, finer tasks. If you need to design such a large task, it needs to

I have never been in touch with and learn new technologies for a long time. I have to complain that my company is busy and I am making excuses for my laziness. People who work slowly are not the same as students, and sometimes have the same mentality! Think about it now and miss the hard work of hitting the keyboard late at night in the old age of students!The process engine was not the first contact. Last year, a colleague and I were connected to the OA system of the 10 thousand section. At tha

Document directory 2.1 activity designer V. Basic Framework of workflow designer 1. Net designer . The namespace of the basic framework of the net designer is system. componentmodel. and WF, Asp.net, and win from are all built on. net. The namespace where the WF designer framework is located is system. workflow. componentmodel. design. The relevant classes are all in this namespace. Before studying the

After more than a year of contact with WF, we found that there were not many people who paid attention to WF learning, but many people studied and studied WPF and WCF. Most people think that WF is only used for approval.ArticleTalking about using WF to implementDragBusiness platform. I believe that

// Connect to the previous article Aspnetx said: it provides space for third-party software vendors A. Z said: WF is the packaging abstraction of a series of processes. Nostalgia said: the platform and engine are two yards away. Qu Bin Said: the foundation is not a platform. Artech said: WF, as its name implies, is the basic structure of a workflow and a workflow engine. Aspnetx also said: "The

General Manager interview, which is based on the process. Event-driven workflow: Consider whether our software engineering process is like this: 3.First instance:Hello World Learn anyProgramIn the first exampleHello WorldThis time is no exception. Let's build a simpleWFSmall program. My environment isVisual Studio 2008 +. NET Framework 3.5 SP1To build a project: First, let's get familiar with the environment: Open vs2008 and choose new --> Project: Then select wor

In the WF environment, it is easy to cause an endless loop, because according to the forward-channing reasoning principle, a rule can trigger itself, in which case it will cause an endless loop: IF this. disCount = 10 THEN this. disCount = 10 this statement can easily cause an endless loop. In addition, when there are two or more Rules, it is easy to cause an endless loop:R1: IF this. Name! = "Headchen" THEN this. disCount = 10R2: IF this. disCount =

1. Summary In thisArticleIn, we will mainly learn about the usage of replicator activities, and then we will pass a simulated voteProgramFamiliarize yourself with the Replicator activity. In addition, we will try to decouple the workflow from the specific implementation method in this section. 2. Replicator In the previous article, we learned the IF-else activity and the while activity. We learned the same idea as we learned the basic syntax of the language, we also lack an important

Objective:By now we can see that WF4 contains a designer for a. xmal file and a runtime that invokes the activity. When you create your own workflow, you are also creating an activity,Because the activity is a class that inherits System.Activities.Activity.Activities can implement business processes, and some activities implement business processes by invoking other activities, such as sayhello activities that do not write text to the console, but rather through WriteLine activities.To achieve t

Microsoft's WF is a good workflow development platform. Compared with the Open-Source Workflow implementation, its designer is not very beautiful (of course, this is also quite different from the connected designer I have seen before.) I suddenly came up with an idea last week. Can I implement a similar workflow designer on the web page ?! We all know that it is difficult to draw a line on a web page using JS (in fact, it is impossible to draw a line,

1 Structural Analysis Reference: MSDN http://msdn2.microsoft.com/zh-cn/magazine/cc163466.aspx WF Monitoring Reference below: WF allows multiple tracking services (that is, you can add multiple trckingservice in wrokflowruntime), allowing multiple tracking service to be added to the runtime to support different business requirements, the tracking service is responsible for specific implementation, But ther

Comparison between WF and Windows -- Interpreting the core principles of WF through AEC (11) (additional topic) Sometimes, during Activity development, there is always a feeling similar to the previous one, such as C, if I forget to release the pointer, I will always hit myself. When developing the Activity, I forgot to Close and I will hit myself ...... I think the structure of

This series of articles will start from the instance and end with the instance. This article explains how to use WCF and WF in our project. We will find that using WCF + WF will create a level that other technologies cannot reach. Finally, I will host the program on the cloud. Microsoft. NET's 3 W (WPF, WCF, and WF) strategy is as follows. WCF is responsible for
