Wf4 Persistence: SqlWorkflowInstanceStore2010-06-07 10: 33  I will systematically introduce the persistence service in wf4. Wf4 provides an abstract class instancestrore, which indicates the container of the logical workflow instance. There

Async is asynchronous, but its function is to call the Asynchronous Method activity synchronously. Asynccodeactivity inherits activity as an abstract class. Override uses the [cachemetadata method] and provides two Abstract METHODS: [beginexecute]

There are two types of properties in the activity Property Window. One is the common property mentioned in section 2nd, and the other is the property of the event type. You can use this property to create an event. For example, you can use the

Properties of workflowinstance Attribute Function Instanceid Obtain the unique identifier (guid) of the workflow instance) Workflowruntime Obtain the workflowruntime of this workflow instance.

Condition:Spworkflowtaskproperties. sendemailnotification = true Note:Each time "createtaskactivity" or "completetaskactivity" is executed An email notification will be sent to all "spworkflowtaskproperties properties" activities. "Assignedto"

Event is an important concept in Windows-based programming. In almost all Windows applications, a large number of asynchronous calls are involved, such as responding to and Clicking buttons and processing Windows system messages. These asynchronous

Interaction with powershell in wf4 beta1 provides two activities: invokepowershell and invokepowershell . Invokepowershell: Call A powershell cmdlet that does not contain the returned value. Invokepowershell can be used to call simple lelets and

The following is an activity. After an activity is added to a workflow, the activity constructor is called three times during workflow compilation. Can you explain it in detail? Public partial class activity2: sequenceactivity{// Private Static

    In many cases, an employee in an enterprise may belong to both Department A and department B. In department A, an employee may assume one role and another role in department B, this kind of organizational structure violates the basic

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

Note that the DependencyProperty attached property, not the binding property First look at a hypothesis, How to extend a member of a class without modifying a class (inheritance is not possible) This is not possible in the traditional OO design,

Many years ago, the Windows Workflow Foundation was called WWF, and the literal translation of the name made many people think it was used to develop workflows or simply approval flows.Bo Master was still a ignorant teenager, but also know that Microsoft will not vigorously push a face to such a business scenario of the technology, so specifically to find a "WF essence", when the "program is data" This assertion, was deeply shocked. Perhaps this is ju
