wf 2540

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

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

Everyone knows that in WF, by default, its activities are composed of tree structures. Simply put, a composite activity contains its subactivities. If a subactivity is a composite activity, it can also contain its subactivities, however, a single activity cannot be a subactivity of two activities. This method is widely used in the activity library of WF, such as loop and conditional activity.This method has

After completing this chapter, you will learn: 1. Learn which components are required to create a full-featured custom workflow activity 2. Create a basic custom workflow activity 3. Apply validation rules in basic custom workflow activities 4. Integrate basic custom workflow activities into the Workflow View Designer and toolbox of Microsoft Visual Studio WF is not likely to cover every aspect of what you might want to achieve in your workflow.
