7、Creating aVisual Studio 2008 State Machine Workflow Project First,you create aVisual Studio project to build your workflow.To create aVisual Studio 2008 State Machine Workflow project建立一个sharepoint 2007状态机工作流项目Open Visual Studio 2008.打开vs2008 On the File menu,point to New,and then click Project.打开文件
8、-新建-项目Under the Office Project type,select the SharePoint 2007 State Machine Workflow project template.选择Office里面的sharepoint 2007状态机工作流In the Name text box,type ExpenseReportStateMachineWF,and then click OK.在名称后面的输入框里输入ExpenseReportStateMachineWF,然后点确定。Type avalid SharePoint Server Web URL.This scen
9、ario uses Click Next.在有效的sharepoint web url下面输入你的sharepoint地址，并加上你要附加工作流的文档库名称,例如：然后点击下一步。Select alibrary or list to associate with the workflow,or accept the default.Click Next.库或列表后面的选项是选择你要附加的库或列表，然后点下一步。然后点完成。Rename the StateMachineWorkflowActivity from the default workflow1.cs to ExpenseReportS
10、tateMachineWorkflow.把workflow1.cs重命名为ExpenseReportStateMachineWorkflow.cs Laying Out aState Machine Workflow设计你的状态机工作流Now you can set up your workflow.You start by laying out the workflow in the designer and updating all required properties.Later,you add the code to drive your workflow.现在，你可以设计你的工作流
11、了。开始是在工作流设计器里面拖放工作流控件，并设置它们的属性。然后就是给你的工作流添加代码了。To lay out astate machine workflow开始设计工作流By default,the workflow contains astate named Workflow1InitalState.Open the Properties window and rename this state to ReportInitialState.For now,do not worry about the EventDriven activity eventDrivenActivity1；y
12、ou will return to that later.工作流里已经默认包含了一个名为Workflow1InitalState的状态。在它上面点右键，选属性，在属性窗口里把名字改成ReportInitialState。现在你还不用管它里面的eventDrivenActivity1，一会儿我们会具体说道它。Open the Toolbox.Expand the SharePoint Workflow controls and the Windows Workflow v3.0 controls.打开工具栏，点开sharepoint工作流控件列表和Windows Workflow v3.0控件列
13、表。In the Windows Workflow v3.0 category,select State,and drag it onto the designer surface.在Windows Workflow v3.0类别中选择State,并且把它拖拽到设计器中。注：State就是状态机中的状态。Open the Properties window,and rename this state to ReportSubmittedState.打开它的属性，并把它的名字改成ReportSubmittedState。Add three more states to the document
14、surface,and rename them ReportApprovedState,ReportRejectedState,and ReportCompleteState.再增加三个状态，它们的名字分别是ReportApprovedState,ReportRejectedState,ReportCompleteState。Next,set your initial state.Right-click ReportInitialState,and then select Set as Initial State.This adds asmall green circle icon to th
15、e state in the upper-left corner,as shown in Figure 1.接着，设置你的开始状态。在它上面点右键，选设置为初始状态。这时你会发现在这个状态的左上角的小图标里多出了一个绿色的标志。如下图Figure 1.Initial state icon Next,set your completed state.Right-click ReportCompleteState,and select Set as Completed State.This adds asmall red circle icon to the state in the upper-
16、left corner,as shown in Figure 2.接下来，设置你的结束状态。在ReportCompleteState状态上点邮件，选择设置为已完成状态。这个时候你会发现在这个状态左上角的小图标里面多了一个红色的图标。如下图Figure 2.Completed state icon Now that you have all of your states on the designer surface,you must add activities to the states.这样，你的所有用到的状态已经都在设计器中了，下面你该为他们添加activities(行为)了States
17、 support the following activities：状态支持一下几种activities(行为)：StateActivity EventDrivenActivity StateInitializationActivity StateFinalizationActivity You will work with only the StateInitializationActivity and the EventDrivenActivity.这里只需要StateInitializationActivity和EventDrivenActivity两种行为Select the even
18、tDrivenActivity1 in the ReportInitialState state.选择ReportInitialState状态下的eventDrivenActivity1。In the Properties window,select the Name property,and rename it to eventInitWorkflow.在它的属性里面把它重命名为eventInitWorkflow。Drag aStateInitialization activity to the ReportSubmittedState state.Rename this activity
19、to stateInitReportSubmittedState.拖拽一个StateInitialization到ReportSubmittedState状态中。并重命名为stateInitReportSubmittedState。Repeat this for the ReportApprovedState state and the ReportRejectedState state.Rename these to stateInitReportApprovedState and stateInitReportRejectedState respectively.在ReportApprov
20、edState和ReportRejectedState状态中重复上面一步的操作，并把他们重命名为stateInitReportApprovedState和stateInitReportRejectedState。Drag an EventDriven activity to the ReportSubmittedState.Rename it to eventReviewReport.为ReportSubmittedState状态拖拽一个EventDriven行为，并把它重命名为eventReviewReport Note：You cannot drop EventDriven activit
21、ies above the StateInitialization activity；the designer moves the activity below the StateInitialization activity for you.注意：你拖拽的EventDriven应该放在StateInitialization的下面。Your workflow designer should look similar to Figure 3.现在，你的设计器中的工作流应该如下图。Figure 3.Incomplete workflow layout Now,you fill in the det
22、ails of each state.下面，该为每个状态填充更详细的内容了。To add Initial state details为初始化状态添加详细内容To start,double-click the eventInitWorkflow activity in the ReportInitialState state.双击ReportInitialState状态中的eventInitWorkflow。You should see the following.你将会看到如下图。Figure 4.Detail view You can use the breadcrumb links acr
23、oss the upper-left part of the designer to return to the state view of the workflow.你可以通过视图中顶部靠左边的链接回到前面的视图中。First,rename the onWorkflowActivated1 activity to onReportWorkflowActivated.首先，把onWorkflowActivated1重命名为onReportWorkflowActivated。In the Properties window,select the CorrelationToken property
