• Havoc the Humble FileNotFoundException in GetWorkflowDefinition

  When I used GetWorkflowDefinition, I got a FileNotFoundException: Could not load file or assembly 'file:///E:\MyWorkflow.dll' or one of its dependencies. The system cannot find the file specified. MyWorkflow.dll is the DLL containing my workflow definition. If I copy this DLL file to the directory of my program, the problem will be solved. What I don't understand is that, why does GetWorkflowDefinition still need the DLL file now that it is a method of WorkflowInstance Why does the workflow runtime still need the access to the assemblies after the workflow instance has been created by "CreateWorkflow" Why doesn't the workflow runtime load the type to memory in "CreateWorkflow" ...Show All

• Michael Hansen Need to fool VS2k5 Std Edition into thinking I'm an admin...

  Hi. I'm running Windows Vista in Administrator mode and I've disabled UAC. The problem I have is when I choose Web Site link next to open and choose Local IIS, VS2k5 told me I must be a member of the Administrators group on this local computer to access the IIS metabase. However, I AM the owner of my computer and have installed Windows Vista Beta 2 Build 5384 by myself. If I try to create a new website with [code]http://localhost/[/code] and click OK, I will get an error stating either: "The data area passed to a system call is too small" or sometimes I will get an error telling me about the HRESULT or COM object that's something only C/C++ developer can understand; I'm a C# developer.

• fripper Exception on raising an event

  Hello, I'm developing an example project very similar to expense reporting (lab01), with two event handlers. I can fire the first one (submitted event) without any problems, but when I try to raise the second event (reviewed event) I get an exception that sais: "EventDeliveryFailedException was unhandled" and the message is "Event "RevisatCOF" on interface type "WorkflowValidacio.Interficie" for instance id "ef46e5fa-64c7-4343-9d3c-c62b829f9c37" cannot be delivered." I followed exactly the example in expense reporting, so I have the event declared in my interface and in the implementation class, and I raise the event like this: RevisatCOFEventArgs e = new RevisatCOFEven ...Show All

• mmmr how to declare variables used by different activities

  I just have a conceptual question regarding workflow. In my workflow, i declare are the varaibles used by different activites as the instance variable of the workflow class. In this way there are many variables declared as each variable may be altered by one activity while used by another. Is it the right way to declare variable, i.e. declare them as instance variables and use them in different activities or is there some other more efficient way to do it. when you only use code activities, this works; the problem is when you create& use Custom activities : then you should define dependency properties ; by binding the dependency properties you can share their value between the different activities (a ...Show All

• AIMDBA How to realize repeating sequence of activities

  During a workflow there are several places where the same sequence of activities appears. So I want to know what is the best way to create a building block of this sequence: - creating a custom activity (I have a question of understanding: the documentation refers to so called "composite activities". They mention the While activity as an example. But the While activity has dynamic content at design time. But I want something with a fixed set of activities. Is it a composite activiy anyway ) Can someone provide a link to a template of a composite activity with fixed sub-activities - creating a subworkflow including it with InvokeWorkflow at the appropriate positions What are the pros and cons ...Show All

• acm programmer Elevating an IE7 toolbar to Integrity Level: Medium

  Hello, I have an IE7 toolbar that needs to write to an Access DB that resides in the Program Files directory. However, because IE7 runs in Protected Mode, the toolbar does not have access to write to the Program Files directory. So, I tried to move the Access DB to the ProgramData directory. Now, I don't get the Access Denied error, but the toolbar doesn't write to the DB that is in the ProgramData directory. Instead, it writes to some VirtualStore directory. Has anyone run into this Does anyone know how to elevate an IE7 toolbar so it runs with an integrity level of MEDIUM Thank you, "Note Even low integrity files will get redirected by Protected mode's compatibility shim except for kn ...Show All

• Tony Sperling How to support dragging a subnetwork of activities onto the designer?

  Context - Sequential workflow with a number of custom activities - Custom application that hosts the WF designer Question I want to drag a custom activity from the toolbox onto a WF designer surface and when the activity is dropped, a subnetwork of activities appears on the design surface. ...kind of a like a "design macro" activity - drop one activity and an entire activity subnetwork is inserted at the drop point. How can this be implemented using WF Thanks, Michael. Create a custom ToolboxItem and override the CreateComponentsCore to create all of your activities and return them in the array. You can derive from the ActivityToolboxItem if your want to inherit some behavior. Matt When yo ...Show All

• David Mack Handling events when hosting workflow in ASP.Net or a remote object

  I am looking to host workflow within ASP.Net and perhaps a remote object. In both cases it appears best practice to create the WorkflowRuntime once and reuse it for each call. However, having read Dino Espoito's article and looking at Matt Winkler's example I have some questions: In both cases their code registers with the WorkflowCompleted event on the WorkflowRuntime, but the handlers do not check that the workflow that has completed is the same one they started. Am I missing something here If the ASP.Net site was concurrently starting several workflows, how do you know which one you are handling the WorkflowCompleted event for Is it that because they use ManualWorkflowSchedulerService they only get an event raised that is relevant ...Show All

• Erik BN Remote Desktop is the issue, not Vista

  According to some MS documents (e.g. http://www.microsoft.com/whdc/system/vista/services.mspx), it should be possible to use CreateProcessAsUser() API in a Vista service to create a process in user session. I am trying to achive this, but the function returns error code 1307 (ERROR_INVALID_OWNER) = "This security ID may not be assigned as the owner of this object." Does it work for somebody Many thanks in advance. I am doing basically the same thing, but I get "CreateProcessAsUser failed with 123" I have tried everything I cn think of with no luck WTSQueryUserToken with 0 as the session id will always fail on Vista, because no user ever logs on in that session anymore.
