• fasttrack IObjectReference cannot be resolved

  I have a strange problem whereby my workflow is failing when I call the StartRuntime method. My basic workflow works with a few custom activities derived from CallExternalMethod and HandleExternalEvent - I use a replicator to call many events and wait for the correlated response. However, when I add any new items to my workflow like a delay shape I get the following error:- " The object with ID 54 implements the IObjectReference interface for which all dependencies cannot be resolved. " This is some sort of serialization error but I've been unable to find out what is causing it. There is nothing in the designer generated code that uses IDs for the workflow artifacts so I don't know what is being complained about. H ...Show All

• tomavery Naming StateActivities

  Does anyone know why I cant use the Name "closed" on a StateActivity Thanks Adrian It looks like it collides with the Closed event that is defined on the base Activity class. I also tried to use other events like Executing and Compensating and they do the same thing. I do find it strange that it doesn't allow closed, executing or compensating (lower case) since they don't directly match up to the actual event name. Perhaps this is just over-aggressive validation.

• taumuon directshow filter : splitter

  Hi, When I want to run a mp3 file, could you tell me what is doing the mpeg 1 splitter As The mpeg1 splitter splits an MPEG-1 system stream into its component audio and video streams and I have only audio. Thanks a lot moving to DirectShow forum. DirectShow (video support) hasn't been part of DirectX for some time now. ok, thanks a lot for your answer The source filter is pull-mode and the rest of the graph is push-mode, so you need a filter to convert between the two. Typically this filter will also do the seeking and timestamping of samples. So you will often get a demultiplexor in the graph to do these tasks even if there is no actual demulti ...Show All

• Nigel Harper Modeless/non-modal file dialog

  In the application I'm working on we are using a modeless file dialog. This is realized by hosting the CFileDialog instance in a separate thread. The parent window of the file dialog is the app's frame window. This ensures that the file dialog does not create an entry in the Windows taskbar and the file dialog is always on top of the app window. This worked fine with previous Windows versions (NT, W2K, XP). With Vista we observe a strange behavior. Assume the modeless file dialog is running and it contains a custom button from where we can launch another modeless dialog (its parent is also set to the main frame window). This second dialog immediately disappears behind the app window (!) as soon as it is displayed. Picking into the app wind ...Show All

• Matt_C89 WorkflowQueue and Thread Safety

  Hi, WorkflowQueue is created by the workflow when an instance of workflow is initialized. My question is that, what if several instances of the same workflow is running at the same time, do they share the same workflowQueue Inside the host, the queue items are produced, and the items are consumed in several workflow instances. Is it by default thread safe, or we developer have to synchronize and make sure thread safty Thanks, Jim Thank you Jon for your quick reply. Let's go back to one host, one workflow instance senario, the queue is still synchronized by default between the producer and consumer, is this correct Jim Thank you Joel. WorkflowQueues are per workflow - so they are not shared amo ...Show All

• alpefusk ICredentialProvider

  I have downloaded the Microsoft credential provider samples (beta2). I modified the sample (SampleCredentialProvider) and I can now log onto our system, lock my computer and unlock it. That's fine, but I am facing a problem with this sample in the case of the unlock. At logon, an instance of the CSampleProvider class (that implement the ICredentialProvider interface) is created, this instance creates an instance of the CSampleCredential class (that implement the ICredentialProviderCredential interface). This instance hold the information (username, password, domain) and the GetSerialisation method is called once the submit button is pressed. Up to now everthing is OK, but if I lock the computer and unlock it, a new instance of CSamplePr ...Show All

• Etowah_man Looking for some help on where to start...

  Hi all, I've been looking around and around in samples and posts in the forum but I found nowhere a way to help me on my noob question. It seems like most of you have been using InfoCard in a web environment. Well, I'm willing to use it in a smart client application. Question 1.How can I request Windows Vista to prompt the Card selection to the user... Simple huh Question 2.Then, what I want to do is quite different from the standard challenge request web process: All the users of the application will open a local session (managed by the application) in order to provide an offline mode while making sure I got all the require information. Once the user enters in the online mode, I want to pick the card information and send ...Show All

• kushpaw problem with TBS API function Tbsi_Context_Create

  Dear all, I have a PC with a Broadcom TPM 1.2 chip. I can call the Vista TPM Management Tool to show the TPM chip information and to call TakeOwnerShip.

• Richardthomas1960 createToXAML ?

  Is there any (or will there be any) way of extracting XAML/XML from the plugin It could be useful to be able to process the contents through the XML DOM in some scenarios. Tim You kinda can... I didn't do serious research in that direction, but it is possible to iterate through children of Canvas and get properties of each node in javascript. toString() for the node returns node type, like : 'Canvas'. I 'd expect the ammount of code to handle full wpf/e xaml spec to be pretty big thou.

• progames25 How to remove all persisted workflows from the SQL service via code

  Hi, I need to clear all persisted workflows when starting my application (if one of the services falls). I've been looking through the forum, but I only found a reference to running the SQL schema file for clearing and rebuilding the tables. Is there any way to do this throguh the runtime engine, by code Joni No, there is no built in mechanism for the runtime to remove persisted instances from SQL. You could just do something like the following: SqlConnection connection = new SqlConnection ( "Initial Catalog=SharedStore;Data Source=localhost;Integrated Security=SSPI;" ); connection.Open(); foreach ( string table in new string [] { "InstanceState" , ...Show All

  Which forum should I have used Beginning to think Microsoft tech support is worse than Dells,and that bad.Apple is starting to look better all the time.

  We have a number of products based on DirectShow and DES that we're trying to move to Vista. The released Vista SDK as eliminated the DirectShow Editing Services code samples.
