MOSS工作流开发+Email提醒

这几天，忙于MOSS工作流的任务，所以很忙，研究几天工作流，感觉开发MOSS工作流，其实也很简单。不像大家想象的那样的复杂！

一.介绍

MOSS开发工作六

.开发环境&准备工作

 SharePoint Server 2007

 Visual Studio 2005

 .NET Framework 3.0

 Visual Studio 2005 Extensions for Windows Workflow Foundation

 ECM Starter Kit for Visual Studio 2005

工作流中只有一个onWorkflowActivated活劢,所有SharePoint工作流都必须从这个活劢开始.

onWorkflowActivated活劢有一些属性值得我们注意:

 CorrelationToken : Correlation Token 是将若干相关联的活劢映射到同一集合的标识符,其作用不某些编程语言中RadioButtion组件的GroupId属性类似,注意丌要为任务活劢和工作流活劢指定相同的CorrelationToken.

每一个Task都是一个SequenceActivity (IfElseAcitvity和ParallelActivity的分支也是SequenceActivity), 它依序包含CreateTask,onTaskChanged,CompleteTask和DeleteTask四个活劢,代表了一个任务的一次生命周期.

 同一组Task活劢都必须设置相同的CorrelationToken属性和TaskId属性(在本例中同一组Task活劢都包含在一个 SequenceActivity中);而丌同组的Task活劢则需要设置丌同的CorrelationToken属性和TaskId属性.

 Task活劢的OwnerActivityName必须设置为包含它们的SequenceActivity名称.

 将onTaskChanged的afterProperties属性设置为和CreateTask活劢的TaskProperties属性相同的变量(这样做的目的是默认保存用户对Task的修改).

六.部署

关亍部署的文件Feature.xml , Workflow.xml和Install.bat.

6.1 强签名

因为工作流的程序集需要部署到GAC里,所以我们需要为程序集生成一个强签名.

 拷贝并注册工作流表单.

 将程序集添加到GAC.

 安装并激活工作流feature

大家明白上面的理论知识拉，现在开始开工，我也不在这里废话拉，

首先跟大家讲讲我这个工作流的流程-〉首先用户提交申请，然后流程启动-〉发送EMAIL-〉通知审批人-〉审批人审批通过-〉然后-〉提交到人事部门list,等待以后察看，流程结束。

程，设计如图：

我这几天也在做相关工作。工作流表单是用infopath做，感觉wff是很强大，但infopath的页面编成太痛苦，比如要在infopath内实现个数型菜单，不知道怎么弄，工作流表单用asp.net页面好像也可以，不过没弄过，有例子没？给个，还是对asp.net页面编程比较容易。回复引用查看

#7楼 [楼主] 2007-06-27 09:29 AA(Show)

其实,MOSS的工作流开发,他的流程是直接跟任务挂钩的,流程关联与任务.

所以,不管是用InfoPath 还是 asp.net叶面,还是别的..都一样,流程设计好,就OK. 回复引用查看

工作流开发很麻烦的要有心里准备！

涉及到多分支和对任务页面进行控制的时候很头疼回复引用查看

#9楼 2007-06-27 10:06 Bruce Lee

审批需要审批表单的，表单与工作流要有数据交互的。我不是说任务处理。请告诉我怎么用asp.net做审批表单，主要是部署问题，用asp。net做任何效果的界面和后台代码没问题，关键是这些页面怎么和工作流的任务挂起来，进行数据交互。回复引用查看

后台代码只能在layout目录下作手脚

另外对工作流的数据收集是通过INFOPATH 来作的

如果用ASP.NET来收集数据的话那工作流中的任务扩展属性怎么办

头疼阿！回复引用查看

#13楼 [楼主] 2007-06-27 10:57 AA(Show)

对 by ad 哥们说的好！

用MOSS扩张创建List Definition aspx模板，做好的WFAssoc，WFInit都要放到layouts下面，

这个是 workflow.xml

AssociationUrl="_layouts/WFAssoc.aspx"

InstantiationUrl="_layouts/WFInit.aspx"

ModificationUrl="_layouts/WFMod.aspx">

至于任务，

大概就是

TaskWorkflowContentType，我们的aspx创建的模板是List Definition 创建的。所以。。可以参考下面代码：

protected SPList List;

protected SPListItem m_task;

protected SPWorkflow workflow;

protected string m_taskData;

protected string m_taskName;

protected SPWorkflowAssociation assocTemplate;

protected InputFormTextBox Description;

protected InputFormTextBox Comments;

protected Button btnSave;

protected Button btnFeedback;

protected override void OnLoad(EventArgs ea)

{

base.OnLoad(ea);

string strListID = Request.QueryString["List"];

if (strListID != null)

List = Web.Lists[new Guid(strListID)];

m_task = List.GetItemById(Convert.ToInt32(Request.Params["ID"]));

try

{

Guid workflowId = new Guid((string)m_task["WorkflowInstanceID"]);

workflow = new SPWorkflow(Web, workflowId);

}

catch

{

throw new SPException("This list item has not been created by a workflow. You cannot apply this content type");

}

SPList listWF = null;

try

{

listWF = workflow.ParentList;

}

catch

{ }

if (listWF == null)

throw new SPException("The association has no Parent List");

SPWorkflowAssociationCollection wtc = listWF.WorkflowAssociations;

assocTemplate = wtc[workflow.AssociationId];

m_taskName = (string)m_task["Title"];

if (!IsPostBack)

{

FetchTaskInfo();

}

#region Helpers

private void FetchTaskInfo()

{

if (m_task["Description"] != "" && m_task["Description"]!= null)

Description.Text = m_task["Description"].ToString();

else

Description.Text = "No instructions were provided for this task.";

Comments.Text = (string)m_task["Comments"];

if (m_task["Status"].ToString() == "Completed")

{

btnFeedback.Enabled = false;

btnSave.Enabled = false;

}
