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,

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 servi

1. Summary We have been familiar with the basic concepts of WF before, and I believe you are eager to try it. I want to enter the real WF development. From the beginning of this article, we will first familiarize ourselves with the activities in WF. 2. Activities The core of WF is a series of activities.

(); }} Through this development instance, you can realize how to use InvokeWebServiceActivity to call Web Services. All in all, through the Web Service andWorkflow workflows can be called to develop complex business layers. In the next article, we will introduce how to implement mutual calls between the WCF and Workflow workflows,Coordinate the work. Mutual invocation of WF workflows and Web Ser

This is a WPF workflow designer, Prepare to develop a process designer for Silverlight. A previous graphic UI example has been released. This example is the DEOM before the official development of Silverlight. In addition, most of the articles on architecture are about [Data Service Platform (front-end UI + middle layer + Data Storage)], and the architecture design of tool applications is relatively less. if you are interested in this architecture des

After completing this chapter, you will learn: 1. Invoke Web Services in your workflow 2. Adding and configuring Web service proxies 3. session (sessions) management in your workflow For me, some of the data sent and received based on the network is very attractive to me, and for many years I have enjoyed writing code based on communication. When I see WF's ability to connect to Web services and serve a

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.

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 synt

1. workflow development style In WF, there are three ways to develop workflows. Here, I don't want to take the time to give an example. The workflow layout is in The XAML format. I believe that those who know about WPF and sivlerlight know this clearly. In fact, this is the same as WF. This is the

After completing this chapter, you will learn: 1.workflow Optional Service 2. Create an event Tracking database 3. Activate Event Tracking Service 4. Create a custom trace 5. View your workflow tracking information So far, we've seen some basic objects of workflow. We create workflow tasks through activities that

In the previous article, I used examples to explain how to dynamically load xoml creation and running processes in. NET Framework 3.0 (3.5. This article introduces some important changes of WF 4 in WF 4.0. In WF 4, XAML (note, not xoml) is used by default, and C # Code cannot be included at the same time. In WF 4, s

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

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 design

In this section, we will learn how to call a workflow through other programs, and transfer some data to the workflow at workflow startup so that it can be used in the workflow. When workflow starts execution, there are two ways to pass data to the

1 Net Designer Foundation framework The namespace for the. NET designer infrastructure is System.ComponentModel.Design, and the three designer architectures for WF, ASP.net, and win from are all built on. NET itself provides the underlying framework. The namespace for the WF designer frame is System.Workflow.ComponentModel.Design, and the related classes are in the namespace. Before researching

In this chapter, you will use the flowchart activity to create a workflow. Just like its name, a flow chart activity is like a flow chart, which is connected by a decision tree. With a sequence activity, its subactivities can only be executed from top to bottom. In a flowchart activity, its subactivities can be executed in any order. Create a flowchart Workflow Create a project and select the
