Design business process platform based on WF _ multiple statuses of the same process A status chart is a design chart that is frequently used in workflow design, When talking to me about the status chart, many process designers often say that they are familiar with the legends of the status chart in UML, but every time they draw a status chart of the business process, I always feel that the painting is not easy. In fact, when drawing a state char

Previous Article: WF from entry to entry (Chapter 6): loading and detaching instances After learning this chapter, you will learn about:1. Know how to use Sequence activities2. Know how to use Code Activity3. Know how to throw an exception in the workflow and handle it.4. Know how to pause and terminate your workflow instance in code In this chapter, we will officially introduce a set of activities that we have seen earlier: Sequence activities and Co

Developers are increasingly using service-oriented architecture (SOA) as a way to build distributed applications. For inexperienced people, designing and implementing service-oriented distributed applications can be daunting. However, Microsoft. NET Framework 4 Enables Windows Communication Foundation (WCF) services to be implemented using Windows Workflow Foundation (WF) more than ever More simple. WCF Workflow Services provide an efficient environm

In the previous article, we mentioned that SharePoint is a workflow platform that encapsulates the event-driven interface on top of the WF workflow engine; SharePoint extends a lot of activity on WF, where three common activities that are closely related to WF are: ONWORKFL Owactivated,createtask,ontaskchanged. A simple SharePoint sequential stream. onWorkflo

start with this. We will build the necessary system to meet the thread data serialization to carry out data transfer between computers or between processes. Create Externaldataservice Service When a workflow communicates with its host, the workflow uses queues and messages when it sends and receives data. The more we do with WF, the more we can focus on the solution of specific tasks in the application. Workflow internal Process Communication For

After you have completed this chapter, you will learn: 1. Use workflow in your application 2. Understand the basic functions of the "WorkflowRuntime" object 3. Know how to start and stop the workflow runtime 4. Ability to use a variety of workflow runtime related events When you perform a task in a WF environment, you need something to oversee the execution process, which is the object named "WorkflowRuntime". WorkflowRuntime to start a separate

Overview A workflow is a modeling of a business process. When designing a workflow, we must first analyze the steps that need to be taken during the business process. Then, we can use WF to create a workflow model to simulate the business processing process. We know that WF contains two types of workflows: sequential workflow and state machine workflow. A sequential workflow provides a series of organized s

Previous Article: WF from entry to mastery (chapter 2): workflow Runtime After learning this chapter, you will learn about:1. initialize a workflow instance in either of the following ways:2. determine the status of your running workflow instance3. Stop a workflow instance4. determine the reason for your workflow being idle or terminated A workflow instance consists of one or more activities. (We will start to introduce various activities in chapter 7

After completing this chapter, you will learn: 1. Understand why workflow instances are unloaded and reloaded and their timing 2. Understand why the workflow instance should be persisted and its timing 3. Build SQL Server 2005 to provide support for WF and workflow persistence 4. Use of SqlWorkflowPersistenceService services 5. Loading and unloading instances in your workflow code 6. Enable the persistence service to automatically load workflow

Firstly create a WF service which act like normal WCF Service to be our service for testing. 1. Create a WF console project. 2. Add a class which is responsible for building a workflow. Here is the code. Class Receiveandreplyworkflow { Public Workflowservice getinstance () { Workflowservice service; Variable Int > X = New Variable Int > {Name = " X " }; Variable Int > Y = New Variable I

I found three instances that run WF under ASP. NET and all of them run successfully on my computer. Two of them are found online at the following addresses: WF (Windows Workflow Foundation) workflow Learning (1) an ASP. NET state machine verification program and WF (Windows Workflow Foundation)Workflow Learning (2) an ASP. NETExample of combining with a seque

A wf-based business process platform After the Chinese New Year, I learned WF from all my friends who followed my blog and asked me how to publish a workflow platform I developed with WF for your reference. This platform is suitable for the work environment that focuses on approval and can be used directly as a product (the platform is directly used by existing

Overview: This demo mainly explains how to use the WCF Service in wf4 and how to call the WCF Service in Silverlight. Because Silverlight is used to render the UI, and the database is accessed by using LINQ. Therefore, the name of this article is "an example of combining Silverlight + WCF + WF + LINQ ". If you are like me and have a little understanding of WCF, you will know that WCF can put many methods in a URI for you to call. So how can we put m

Objective The full name of WF is Windows Workflow Foundation, The first contact WF was in 2004, when Microsoft launched a CTP version of the development package, WinFX. In the WinFX provides three content: Avalon, Indigo, Winoe at that time all three aspects of the content I have involved Like many of Microsoft's technologies, WinFX has no follow-up after Bata2. Fortunately for me this year-long technol

WF workflow instance persistence (passivation) is very important in workflow projects. In actual business, almost all business flows can be completed after a long time, in this way, the unfinished business flow needs to be persisted to the database or file. WF itself provides the sqlworkflowpersistenceservice service to support instance persistence. PublicSqlworkflowpersistenceservice (string connecti

[Stick to the top] Stick to learning WF Article Indexes This article mainly introduces the basic knowledge of the state machine workflow in WF. The state machine workflow and sequential workflow are different. Ordered workflows are generally relatively fixed and predictable, and there are many interactions with the system. State Machine workflows are generally unpredictable, and there will be more interac

[Stick to the top] Stick to learning WF Article Indexes WF regularly checks the persistence point and saves the workflow instance to the persistent storage. In this way, information related to the workflow is stored if an error occurs or the workflow ends abnormally, the next time the workflow instance is loaded, it will start from this point. This is mainly for work-embedded services. The external ser

When I recently studied WF, I encountered an unknown error, such as the error message. Error 102 extend "Microsoft. activities. build. validation. validationbuildextension "triggers" system. XAML. xamlobjectwriterexception "type exception:" For type "founder. framework. workflow. WF. data. when taskactivity constructor executes a call that meets the specified binding constraints, an exception is thrown. ".

1. Summary In the above article, we used ifelse to simulate a login process. In this article, we will use while to simulate a guessing game. In recent articlesArticleI will have some simulated small examples to explain the usage of the specific active control, but it is just a small example. In actual engineering, we all use WF to build an overall macro framework process. This is not a small example and we hope you will be familiar with it.
