Through this section, you can get a preliminary understanding of the features of the WF program and provide a preliminary perceptual knowledge for future WF application development.

Control WPF animation with WF Process This time the subject is WF, not just approval This article uses a small example to demonstrate how to define an animation in WF to control the animation of the WPF page element. The purpose of this example is to let everyone know the application of WF from another perspectiv

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

Code: Overview Data is transmitted through the use of variables. Variables and parameters used in the activity [In parameter]. The value of the correlated variable can be passed In. When the parameter is modified internally, the correlated variable is not changed. [Out parameter] The correlated variable value cannot be passed in. When an internal parameter is modified, the associated variable is updated. The value of the [In/Out parameter] correlated variable can be passed In. When the int

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.

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
