wf 2650

We've written workflows on C # and XAML, or some people feel that workflow written on XAML has little merit, but XAML actually has some very special advantages.1. XAML supports Workflow Designer, C # does not support;2. xaml can be dynamically loaded without having to compile him in a specific location. Dynamic workflows can provide some good features for applications that need to generate business logic or make a runtime decision, and here's how to implement a dynamic XAML-based workflow:

Preface Recently, I made a GIS website and used sliverlight, WCF, and WF functions. When I sent my ideas to other people, many problems occurred during the release of the project, the solution is briefly described here.Sliverlight version Problems After you reconfigure the environment, you will often find that the Visual Studio prompt is similar to "cannot start debugging. Sliverlight developer Runtime is not installed. Please install a matching versi

inIordermanagement.HandleexternaleventactivityThis API is used to call the workflow status externally so that the workflow can continue to run.CallexternalmethodactivityIt is used to call external code to access the Code of business concern, such as determining whether the inventory meets the requirements, and then determining the workflow running path through the return value. 7Implementation Here, I have defined four States and it is easy to know the meaning of each state by name.

4, you can use flowchart activity to model a workflow as a flow chart. Long-running process (long-running process) Execution units of programs that do not return immediately and can be restarted across systems. Durability Save the workflow or service status to persistent media so that it can be detached from the memory or restored after a system failure. State Machine) A well-known modeling example that represents a program component as a single State linked

VS2010 automatically generates a template with the extension xamlx, 2. Add two activities to the template: [Receive] and [Send]. [Receive] is used to Receive client requests and [Send] is used to Send messages to the client.

Database primary key design description In my release example, a WF-based business process platform, N12345B // Almost all data structures use the Guid data type as the ID. Does this ID only serve as the serial number? This ID is not used for the relationship between all tables, and xxxNo is used. // Here, I will explain the reasons for using this GuidWhy do I add a Guid column to each table? This is because I want to process concurrency, which is

event could not be completed as scheduled. Zhang San could send a notification of cancellation, which is a bit like a transaction, but pay attention to it, zhang San can also send an activity extension notification Okay, no nonsense. I have already written more than 20 things. I will not mention this article. The exception capture and resource compensation WF applications will be introduced below.1.

Different from Rete-based in BizTalk AlgorithmAnd WF only uses Deduction of priorityProcess to analyze the results. It is based on the object instance rather than the type. 1) First, sort the rule in the ruleset by priority. If the priority is the same,Sort by the name of the rule.. And all pending tags are set to true (meaning whether the current rule action has been executed and can be used as a candidate for re-execution ).2) Calculate the con

Appfabric bearer service procedure For services that contain WCF and WF, if you want to run and manage and maintain them for a long time, appfabric is undoubtedly a good choice.

WCF and WF. Advanced topic log settings and cleanup in use Tracking level: the number of logs generated by different tracing types varies greatly. Therefore, you need to set the tracking level based on the actual situation and Set Tracking and diagnosis only when tracking errors are required, this method produces a large amount of logs, which facilitates finding clues when handling errors. Because log files are constantly recorded, it is necessary

A new project in the lab involves OA and workflow. Although I know something about it, I have never done it. I have to spend some time learning about it. Collect several excellent WF sites in China and learn about them first. I cannot figure out how the workflow of the B/S structure is automatically completed ???

a service does not necessarily require WCF, but actually using WCF can make the task of creating a service get twice the result with half the effort. WCF is the implementation of Microsoft's definition of a series of industrial standards, including service interaction, type conversion, envelope aling, and management of various protocols.
