The obvious solution to this is to reference the workflow runtime from a container class you create and then stuff that into the ASPNET cache In fact, this is very nearly what happens The WF team knew people would want to use the workflow runtime from ASPNET applications, and they knew that starting the workflow runtime could be problematic, so they created for us the WorkflowWebRequestContext class WorkflowWebRequestContext neatly solves a couple of problems for us For one, it maintains a singleton instance of the workflow runtime When you use its CurrentWorkflowRuntime accessor, it creates the workflow runtime for you if the singleton instance of the workflow runtime is null If the workflow runtime has already been created, the cached workflow runtime is returned This is exactly the pattern we ve been using throughout the book with the WorkflowFactory class introduced in 2, The Workflow Runtime. c# create pdf with password C# - remove password protection from PDF document ...

Remove password from the encrypted PDF document ... We'd better detect if a document is password protected or not before we try to open it. This article presents how to determine if a PDF document is encrypted with password using Spire. The dimension can now be processed, but what will happen when you view measures with the Category attribute 21 Deploy the project, switch to the Cube Designer, click the Reconnect button on the toolbar of the Browser tab, drag Color off of the grid, and then drag Category to the grid on rows With Category, you see the same behavior with Sales Amount Forecast that you saw previously when Color was on rows Even though the DSV has a join between Subcategory and Category, it is the attribute relationship in the dimension structure that determines whether or not aggregated values can be derived for an attribute that is not the granularity attribute for a measure group 22. The other problem it solves is all Web resources have access to WorkflowWebRequestContext and can therefore gain access to the workflow runtime.. reader.Close(); catch (System.Exception ex) { throw new System.Exception("Problems parsing source file: + ex.Message); With a mechanism in place for retrieving the single workflow runtime destined to be used by our ASP.NET application (good for pages or XML Web services), we now need to turn to adding the services we require. We require at least one service, but more could be necessary. The service we need to add to the runtime is the manual thread scheduling service, but the persistence and transactional services are also commonly added. You might at first believe that services are added in the same way we ve added them throughout the book. That is, you might think the following approach would work: Now that you ve seen how attribute relationships affect the aggregated values of measures, restore the attribute relationships in the Product dimension to the original state by removing the Category source attribute from the Product target attribute and placing it under the Subcategory target attribute 23 Switch to the Dimension Designer for Product, drag Category from beneath Product, and drop it in the space labeled <New Attribute Relationship> beneath Subcategory The next time that you browse the cube, after the project is deployed, you ll see the correct aggregated values for Category across all measure groups..
