• Floppy_pillow Problem in ASP.NET's Global.asax with June CTP

  Hi I've got a web app that uses WF which was working fine with Beta 2.2 but no longer starts with the June CTP RC build. Everything compiles ok, but I get the following exception when I start the app from Visual Studio: "Object reference not set to an instance of an object". This seems to be thrown from the usual code in Global.asax that sets up the workflow environment: void Application_Start(object sender, EventArgs e) { System.Workflow.Runtime.WorkflowRuntime workflowRuntime = new System.Workflow.Runtime.WorkflowRuntime("WorkflowRuntime"); Application["WorkflowRuntime"] = workflowRuntime; workflowRuntime.StartRuntime(); } The stack trace references the line 'workflowRuntime.StartRuntime()' and can be seen below: [NullReferenceExc ...Show All

• bikerchick How do you pass data from an html web form back to the custom form activity (to the XOML only state workflow)?

  Matt/All WF Gurus,   We are creating a custom Form activity that will load a web html form and retrieve results back into the XOML only state workflow.  We can program the form loading in the browser from a custom activity, but are not sure how to retrieve the data from the form directly into the state workflow so that the workflow can persist this data and continue working with this data (from the form).   How can you pass data back from a web form directly into a running workflow during an idle state (XOML only state workflow using WF 3.0)   Any suggestions     Sincerely, John Portnov It is part of the SDK (Windows SDK now) and is a command line tool tha ...Show All

• somecrazyguy Exciting Possibilities.

  Hi everyone! I have only just discovered Workflow Foundation and it seems very exciting to me. I would like to ask the wise heads of this forum how to tackle my application. I am developing an IVR (Voice XML) development tool, and would like to use Workflow Foundation (if it makes sense to do so), so it would need to be hosted outside Visual Studio. The application will allow a user to drag an drop activities and behind the scenes the VXML code will be created (so I don't think I need to generate CS or VB code). Also, I don't have any intention of trying to run the VXML in my application, it simply is a creation / editing tool. A very basic IVR script could look like: New Call -> Play Welcome Message (wav file) -> Play Menu Options - ...Show All

• Enix591 How can I access the xml document which my workflow start with?

  Hi My workflow will be associated with infopath form documents,and I want to access some data in that form inside my workflow activties in runtime. please tell me which object or api should I use to accomplish this. thanks in advance Hi Josh - there is no special API we ship for dealing with Infopath documents in WF. I am not sure if Sharepoint team has any special activities [custom activities written by them] that will help read/write infopath documents directly. At the core of it, infopath documents are xml documents so you should be able to use the .NET xml classes to read/write. How you use it inside workflow is really very varied. You could write the .NET code inside a CodeActivity, or have it in the event handler ...Show All

• LEPScapa Test Case 30 - Restart Manager - quite shutdown

  Hi, I'm running through test case 30 and noticed if I issue the shutdown command, my application prompts me to save the current file before it shuts down. At the time the shutdown command is issued, the app was not "running or performing any operations" (TC 30, note 1). If the app has no file open, or the the the currently opened file has already been saved, the app shuts down quietly. Any opinions as to whether or not the above behavior meets the requirement that the app responds "to shutdown messages using the Restart Manager API quietly without user interaction while idle" Thanks. Wes The minimum requirement is that you shut down, any decision to save or restart is up to you. I r ...Show All

• Keithyboy1 Uninstall of our product pops-up a strange explorer.exe crash dialog

  The product that I work on has a Wise based installer, and when we uninstall the product, you get a pop-up saying that explorer.exe crashed. There is no visual evidence of the main explorer.exe crashing, and the task manager does list a second explorer.exe process running. Our uninstall is removing some file types and mime types, and does an SHChangeNotify(SHCNE_ASSOCCHANGED), but nothing that looks like it should crash anything, let alone explorer.exe.
