SharePoint state machine Workflow

Develop vs2005 + sharepoint2007 + infopath2007

First, your custom list contains two fields, specifying the level-1 approver (staticname is firstapprover) and level-2 approver (staticname is secondapprover)

If you submit a ticket (task0) to Task 1, Task 1 can return the ticket to task 0, task 0 can choose to return the ticket to the End Process, Task 1 can be submitted to task 2, Task 2 can approve the process and end the process, or you can return the ticket to Task 1.

A special note:

Insert workflow. XML using the method of inserting external code segments

<Elements xmlns = "http://schemas.microsoft.com/sharepoint/">
<Workflow
Name = "My Workflow"
Description = "this workflow ..."
Id = "guid"
Codebesideclass = "projectname. workflow1"
Codebesideassembly = "projectname, version = 3.0.0.0, culture = neutral, publickeytoken = publickeytoken"
Tasklistcontenttypeid = "0x01080100c9c9515de4e24001095074f980f93160"
Associationurl = "_ layouts/cstwrkflip. aspx"
Instantiationurl = "_ layouts/iniwrkflip. aspx"
Modificationurl = "_ layouts/modwrkflip. aspx">

When you generate a project

The sequential workflow in SharePoint generates codebesideassem = "projectname, version = 3.0.0.0, culture = neutral, publickeytoken = publickeytoken"

In Sharepoint, the state machine workflow generates codebesideassembly = "projectname, version = 1.0.0.0, culture = neutral, publickeytoken = publickeytoken

I will not talk about anything else. The source code of the state machine workflow.
