Preface

WF4 is a process engine, as well as a visual program language, shipped along with Microsoft

.NET Framework 4.0. Traditionally, when we design a long-running application, we break

a large application into lots of small code blocks to address the business logic and use a

database to store the intermediate data. With the growing complexity of logic, managing code

blocks and authoring logic workows becomes difcult. Now, with WF4, we can design and

create distributed, long-running programs easily.

The aim of this book is to provide a step-by-step guide to help us start WF4 programming.

Every recipe in this book is runnable.

What this book covers

Chapter 1, Workow Program, provides recipes that will help us understand basic information

about WF4 programming.

Chapter 2, Built-in Flow Control Activities, provides recipes that demonstrate the usage of the

built-in control activities.

Chapter 3, Messaging and Transaction, provides recipes that demonstrate how to send and

receive WCF messages in workow. The second part of this chapter focuses on applying

transactions in a workow program.

Chapter 4, Manipulating Collections, demonstrates how to manipulate collection data in

workow programs with WF4 built-in activities.

Chapter 5, Custom Activities, demonstrates how to create our own custom activities; the most

powerful unit of workow.

Chapter 6, WF4 Extensions, demonstrates how to use the built-in extensions such as

persistence and tracking, and also how to create our own extensions.

Preface

Chapter 7, Hosting Workow Applications, mainly explains how to host workow applications

in IIS7. This chapter also provides recipes that demonstrate host workow in ASP.NET, WPF,

and Windows Forms.

Chapter 8, Custom Workow Designer, helps us create our own WF4 workow designer with

visual tracking function.

What you need for this book

We need a PC having Windows Vista/7/2008/2008R2. We can also use Windows XP, but it

is not recommended. .NET Framework 4.0 is a must. Once we install .NET Framework 4.0, we

can run workow applications. To develop WF4 workow applications, we should also have

Visual Studio 2010 installed on our computer. To host WF4 as a WCF service in IIS, we should

install IIS7/7.5 in our computer.

Who this book is for

If you nd yourself working with Windows Workow Foundation 4.0 and you have basic

knowledge of C#/.NET Framework/VB and workow, this book is for you. It will be best if you

know both C# and VB, because WF 4.0 expressions can be written only in VB (at the time of

writing). With this book, you will be able to enhance your applications with exible workow

capabilities using WF 4.0. To follow the recipes, you will need to be comfortable with .NET

Framework, C# programming, and the basics of SOA and how to develop them.

Conventions

In this book, you will nd a number of styles of text that distinguish between different kinds of

information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "The

ActivityLibrary project is for all customized

activities, whereas the WorkflowConsoleApp project is used for testing our customized

activities".

A block of code will be set as follows:

class Program {

static void Main(string[] args) {

WorkflowInvoker.Invoke(GetCodeStyleWorkflow());

}

Any command-line input or output is written as follows:

.NET Framework 4 Full (32-bit) – silent repair

%windir%\Microsoft.NET\Framework\v4.0.30319\SetupCache\Client\setup.exe /

repair /x86 /x64 /ia64 /parameterfolder Client /q /norestart

官网提供的源码，其中有2个源码（hxds-rule和hxds-workflow源码）需要icode和tcode，现已成功破译提取出来！也就是说hxds-rule和hxds-workflow源码不再需要icode和tcode，可以直接使用！

怎么在这个按钮上写if语句<el-button type="text" size="mini" icon="el-icon-delete" @click="handleDelete(scope.row)" v-if="scope.row.finishTime" v-hasPermi="['workflow:process:remove']" >删除</el-button>这怎么写if语句判断根据状态为0展示，为1不展示

nginx location ~* /(ftc-.+)|api|workflow-center|(idms-application-.+)/ 中去除对idms-application-settle的匹配

docker build -t workflow433:v1 报错ERROR: "docker buildx build" requires exactly 1 argument. See 'docker buildx build --help'.

使用shell脚本调用curl 暂停Dolphin 的工作流实例

rm -r -f /var/lib/workflow/tmp/unzip/*

怎么把nginx匹配规则中~* /(ftc-.+)|api|workflow-center|(idms-application-.+)/ 筛选出idms-application-settle走另一个匹配规则呢
