The master who wrote the book lost nothing and the code was not completely copied. As a result, I spent some time organizing the code. I want to thank a man on the Internet for organizing the code, unfortunately, I don't know his name. Today I found these codes in my hard drive and decided to publish them for sharing. Hello everyone. Code Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->Using System; Using System. Collections. Generic; Using Sys

Recently, when I was coding a simple enought WF service program. I found a weird problem by using the WCF test client tool. My WCF endpoint is http: /localhost: 8000/wfservices But if I acess this address in my chrome. I got a message like this. the Service Page has some helpful tips to enable metadata for a WCF Service. unfortunately the same tips do not apply to a WCF workflow service. in previous releases of WCF you had to apply a s

1. Summary Remember the one in "Step by Step WF series (6)-workflow voting simulation project"Program? In that articleArticleWe used a workflow to simulate a simple voting project. In this article, we will continue to improve this voting item. 2. Purpose In the above Article, our voting project is indefinite, but we should consider the actual situation, for example, a vote of the most popular singer, which requires a deadline, for example,

Communication between the host Program and workflow How to pass parameters to a workflow: Define member variables in the workflow: Public String tofolder {Get; set ;} Public String fromfolder {Get; set ;} Public int totalfiles {Get; set ;} When the host program initializes the workflow instance, the parameter is passed in VaR parameters = new

When developing a workflow, I encountered a lot of low-level problems and wasted a lot of time. I will record them here for future reference. There are often some inexplicable problems, such as the failure of breakpoint debugging (including other aspx) for workflows and the failure of applications for new workflows. At this time, IIS has not updated the. NET cache. The solution is to delete files in c: \ windows \ Microsoft. NET \ framework \ v2.0.50727 \ temporary ASP. NET files. Some tim

After Microsoft released the Windows Communication Foundation (WCF) and Windows CardSpace sample programs, Microsoft released the WF tutorial and a large number of examples today, it is a good learning material. Download two compressed packages, including the tutorial and example, in the example section, including the following Application: L OrderingStateMachine L OutlookWorkflowWizard L SpeechApplication L TerminationTrackingService L TrackingP

Designing business process platform based on WF _ message collection and notification Interfaces If a non-system user needs to interact with certain nodes of the business process, as shown in the following figureBusiness Requirements Design Scheme Problems with this solution: Both the receiver and approver have the business responsibilities of notifying the applicant, However, if the applicant is a non-System participant, the information inter

This example was originally intended to be uploaded on Monday, but Qu bin sent me some WPF materials. He thought that WPF wanted high-end video card support, so he never paid attention to it, it's strange that MS's customer service has not been clear about the killing of people with a conventional thinking. I have read about WPF over the past few days. It is a bit like SVG and I like it. In the future, WEB and WinForm can use a set of interfaces. There are two direct consequences of looking at

About dynamic Updates As we develop workflows, we design our workflows in the Workflow Designer by dragging activities, setting properties, and so on, and we hope that the workflow that we defined at design time is unchanged at runtime. But in practice we often need to change the structure of the workflow at runtime, for example, we have defined a process in which we need to add a process point at the end, and this time we need to use dynamic update to reality. In

This paper takes control of a group of logical circuit switches as an example to demonstrate the application of WF in the algorithm, and this article is a combination of [rules engine], we can be a good comparison of the effect of C # code, State machine, rule engine, flow chart in the process control and algorithm of the respective characteristics In the [Rule engine] article, I use C # code separately, WF3. X's state machine workflow, WF3. X's rule

PowerShell provides the function of the command line management system, but in general, the operator to complete a business needs a number of sets of PowerShell commands, this will be cumbersome, error rate is also higher. The operator can write PowerShell scripts to organize orders, This article describes how to use WF to organize PowerShell commands, allowing the operator to care only for specific commands, and to organize logical relationships betw

parallel. In a sense, the same is true of workflow activities. Sometimes, you can't perform a specific activity in a messy or even worse random order. In these cases, you must select a sequence activity to accommodate your workflow. But at other times, you might want to design a process that is capable of performing multiple processes at the same time (or, as we will see, almost at the same time). For these cases, parallel activity is an option. The parallel activity is a composite activity,

Create an external Data service We are now in a more complex section, and our task is to create bridging code for external Data services. The host must have this code to access the data that the workflow instance attempts to pass over. We'll use tools to create activities for the workflow (which is described in the next section), but there are no out-of-the-box tools for communication connections on the host side. Here we will create a slightly simpler version of the connection bridge (this is

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 are managed by WorkflowInstance objects when they are executed. Workflow instances are queued and controlled by WorkflowRuntime. But WF
