• ZUTI How does the serialization work?

  I have the code shown below to serialize a workflow to XML. The workflow consists of custom activity classes, each having its own associated designer. The resulting XML file only contains the names of the activities but not a single property of them. Why are the built-in properties of the activity base classes not automatically serialized Do I need to create a custom serializer for each of my custom activities, even for the built-in properties Is serialization of the activity designer classes also managed by the WorkflowMarkupSerializer or does it only manage the serialization of the activity classes I have many properties for visual appearance in the designers, that I would like to be serialized so that the visual ...Show All

• fripper Concurrent input devices in Vista

  Hi! Is it possible to have multiple input devices in vista, i.e. connect e.g. 2 or more mice and have them used at the same time with 2 different mouse pointers that can interact with different windows at the same time What I want to achive is something simmilar to this for X windows, http://multicursor-wm.sourceforge.net/ Hi I was wondering if you managed to find out any more information about having 2 mouse cursors running from 1 pc, it would be very handy for myself and the company I work for.

• l Bllizzd l EventDeliveryFailedException

  Hello. I already asked something similar to this in at least one other thread. And many other Threads ask about this problem This time I'll post real code, so there are no doubts. In the highlighted line the execution stops saying there is an EventDeliveryFailedException. I know for sure the service is registered in an ExternalDataExchangeService. And I'm sure the HandleExternalEventActivity is listening to the right event form the right interface. And I know through Tracking that the HEEA is in execution. I don't know what to do... public class StandardEventEmitter : EventManagementService.EventEmitter, IEvento { public override void RaiseEvent(System.Workflow.Activities.ExternalDataEventArgs externalEventArgs) { if (ev ...Show All

• david.r.johnson Questions and comments about the DirectShow BaseClasses

  Hello everyone, I have 3 comments about possible bugs in the DirectShow BaseClasses. It is entirely possible that these are not bugs, and in that case, I would be grateful if anyone would correct my misunderstanding. The first bug: when a source stream derived from CSourceStream fails in OnThreadCreate, it is not called on any subsequent attempts to play the graph. This occurs because the thread handle remains open. Proposed solution: in CSourceStream::Active() replace the error check following the call to Init() with: if (FAILED(hr)) { Close(); return hr; } The second bug: when deriving from CBaseReferenceClock, you are expected to override GetPrivateTime() to return the current actual time. This function needs to keep track ...Show All

• Vishor LockProfile of IStreamBufferSink

  I am working timeshift function in Windows vista. I have to use IStreamBufferSink::LockProfile function. But it is failed in Windows Vista. In DirectX C++ MSDN, it is written that This topic applies to Windows XP Service Pack 1 only. How can I do for use LockProfile in Windows Vista Pls, help me. I still say you should file a vista bug. Requiring people to be an admin to use SBE doesn't seem like a good plan. Especially given that vista doesn't want people running as admin in the first place. Had the same problem. It seems to be a permissions problem. I ran the compiled app as administrator and it worked fine. Anyone from MS t ...Show All

• Struan ICredentialProvider

  Did anybody make a successful user logon using the new ICredentialProvider interface My credentials are displayed, but I can't make them to logon. And what worse - after 20 or 30 seconds, the winlogon crashes completely with no recovery possible excepting hardware reset. I thought I basically did something wrong and decided to wait for more detailed documentation or some sample code. But MS doesn't seem to put too much effort on improving their SDK documentation and I also found that at least one other programmer has the same problem: http://msdn.microsoft.com/newsgroups/default.aspx query=vista&dg=microsoft.public.platformsdk.security&cat=en-us-msdn-windev-winsdk&lang=en&cr=US&pt=&catli ...Show All

• TheViewMaster State Machine SQL Tracking DB: How to find Executing activities that haven't Closed?

  I have a state machine workflow with the SQL Tracking enabled (all events - no tracking profile). What is the best/easiest way to query the SQL tracking database tasbles to find the list of activities which have an Executing record but not a Closed record ...i.e. the list of activities that are currently "active" Michael. Thanks Joel. Two options here, either will work depending on what you're most comfortable with: 1. If you don't want to do any tsql coding you can use the SqlTrackingQuery classes and walk the collections of activities and events. 2. Do the query directly in tsql. This would be the approach I would take. Have a look at the tsql code that I posted in http://forums.microsoft.com/MSDN/ShowP ...Show All

• djchapin Help with Exception - please

  I am getting an exception when I try to raise an event in a test project for a WorkflowStateMachine. I am getting an "EventDeliveryFailedException" was unhandled and the inner excption is saying that my Winform that is hosting the runtime is not marked as serializable. Why is the ExternalDataEventArgs trying to serialize the form hosting the runtime The exception occurs when I pass in an instance of the service object as the sender. My event arguments inherit from ExternalDataEventArgs. I don't get what is happening here, I passed in a specific instance of an object that is serializable and somehow when I do, the serialization process ignores my object and tries to serialize the form. This leads me to believe there is a ...Show All

• lk_spec Wifi Interface IP address detection / DHCP / connection / IpHelper API

  Hi, I am currently testing wifi compatibility on Windows Vista. To connect Wifi adapters to network I use my own manager with old oids "OID_802_11_XXX" family and IPHelper to catch IP configuration. This works great for the radio, and my wifi interface become "Enabled" in Network Connection Panel, but DHCP never succeed to give me an IP configuration: Inside cmd tool, by typing "ipconfig", I can see my wifi interface hanging in media state "Media unauthenticated". This is my first problem. Second problem: If I try the same connection using Vista wifi Manager, everything goes right (I pass through "Media unauthenticated" barrier and I catch an IP address).

• MARCOSEDRALIN The UAC Nightmare

  I'm beginning to reach the conclusion that the current implementation of the UAC in Vista is, IMO, a nightmare that creates more problems than it solves. If Microsoft wants developers - and users - to embrace the UAC (instead of just turning it off altogether) then it better come forward with a LOT MORE information and support than it is currently providing! If it doesn't, I will begin to suspect Microsoft only added the UAC so it can tell Windows users 'well, we added the option to secure Windows - you're the ones turning it off' and therefore wash its corporate hands. I would really hate to see this happening. To name just a few of the problems the UAC brings to us developers: 1 - Applications that require Admin privileges are bloc ...Show All

• Janne_K WFDesigner hosting - How to determine the modified state of the designer?

  Hi, I would like to know when the loaded workflow definition inside my hosted wf designer gets dirty. I'm using regular data binding to bind the xoml and rule content to a data set instance. Because of the underlying binding mechanics the property getter will hit a lot and I like to reduce the calls to Save() method. Is there a built-in way to know when the wf designer is dirty In the designer you should be able to get a reference to the IComponentChangeService. This service has events that you can register for that will notify you if a component is changed, added, removed, etc. Once you see one of these events get raised you will know that the workflow has been changed.
