Workflow Solution Framework Overview
Microsoft Workflow Solution Framework is an object frame model based on BizTalk Server 2004 Workflow Services, which is packaged on the API provided by the BizTalk Server 2004 Workflow Services, providing an object-oriented programming model for the upper layer application development.
Before developing using Workflow Solution Framework, we need to make a simple description for Workflow Designer.
In fact, Workflow Designer and Workflow Solution Framework are Workflow Studio, but Workflow Designer is a tool designed to design workflow models and it must be dependent on Visio 2003. We can easily customize the workflow by using Workflow Designer, and load user members into the workflow. Another tool provided by Workflow Studio, we can also easily implement access control for Web Forms, and this design ACL can be imported to the database.
In Workflow Solution Framework, the following components are available: framework.dllhwsimpl.dlluserroleretriever.dltlaction.dll
By programming, we can implement: 1. Access workflow definition 2. Search workflow and task 3, interact with mission ...
Note that in Workflow Solution Framework We must use the built-in role to develop workflow applications, including:
Owner: It represents the owner of a workflow model, all users belonging to this role can access the workflow model unrestricted, regardless of whether he / she actually participates in the workflow instance.
Observer: It represents an observer of a workflow model. All users belonging to this role can access the workflow model in a read-only mode, regardless of whether he / she actually participates in the workflow instance .
INITORCANDIDATE: It can be used as a condition for determining the initiator of a particular workflow model or step, only the user belonging to the role can initiate a workflow belonging to the workflow model or a task belonging to this step.
Candidates: It can be used as a condition for determining a particular step, only the user belonging to the role can be selected as a handler as a task belonging to this step.
Initiator: It represents an actual user, which actually initiates a corresponding workflow or task.
Handlers: It represents an actual user, which is selected as a handler as the corresponding task.
Develop workflows using Workflow Solution Framework, we can develop based on Web Form, Windows Form, InfoPath.
Because this thing is studying, I think about it, I will slowly add it.
