• SimonS_ 64 vs 32

  Does Microsoft have any forcasts in mind as far as what percentage of Vistas sold will be 32bit and what percentage would be 64 bit. I tend to lean towards the 64 bit being in the majority because alot of people will be buying new hardware as well. But I am wondering if there is a forecast available ...Show All

• theblackhat WWF and custom activity. Workflow terminates with exception

  I have created a custom activity which inherits from SequenceActivity. The class name is ApprovalRequestActivity In the designer of my activity I have added a stock Replicator activity. Inside the replicator activity I have added a stock ListenerActivity. Inside the Listener activity, I have two activities one is a delayActivity and the other is a HandleExternalEventActivity. I have dragged this custom activity onto my workflow and it looks good and I can set its properties etc. Further, the solution compiles with no errors. When I execute the workflow through ASP.Net, it seems to initialize my activity because I have added event handlers for the Child_Initialize events. I have also put some logging code int eh Execute method of my activi ...Show All

• glok How to launch Child workflows based on some rules from a Running workflow?

  Instead of binding a workflow at designtime, can we bind the TargetWorkflow of a InvokeWorkflow Activity at runtime You can find an example of a custom invoke workflow activity that can be set at runtime on my blog here . No - TargetWorkflow is a MetaData DependencyProperty and as such has to be set at design-time. You'll need to build a custom activity to do it dynamically. Not knowing how to pass parameters is the reason the InvokeWorkflow is built this way - versus a custom activity you can decide how to pass the parameters. ...Show All

• Robert D Misiak Check Statemachine Status with InstanceID

  Without using the SQL Tracking Service, how can we know the Status / State of a workflow instance with its InstanceID I got an example from the latest Hand On Lab (Lab04), seems the method is too complex, any simple solution about that Andy Ho You can use the StateMachineWorkflowInstance class. It has CurrentState and CurrentStateName properties. If you do add tracking you can use the state machine instance to also get the StateHistory, but you will get an exception without tracking. The following is an example of how to use the StateMachineWorkflowInstance class. Create a new State Machine Workflow Console Application and change Main to the following: static void Main( string [] ...Show All

• Steven Wilmot Launching process in non-elevated mode

  I have setup program that is automatically elevated by Vista. The setup program launches the application using CreateProcess. The application as child process inherits elevated mode of parent setup process. How can I launch the app from setup in normal, non-elevated mode The best practice is to have your initial setup program run "asInvoker", it's job would be to launch the application installer "runElevated" and wait for its completion then launch the app. Launching the application from the installer is often not a good idea: the user might have elevated using a different account. Imagine a user Toby (not a member of the administrator group) clicks on your setup.exe. At the elvati ...Show All

• bruce bubello Windows Card Selector

  It seems to me that when the Windows Card Selector is opened, the whole computer is locked down. But we have to planned to implement a local STS with its own authentication mechanism (displaying a digital signature with PIN entering window). So my questions now: 1. Is there the possibility of any UI interaction during the CardSelector <-> (local) STS communication 2. If yes, is it possible to bypass the definition of UserCredentials in an InfoCard, as we are providing our own authentication mechanism! Maybe you can help me guys. I'd like to know that too, since our target is to configure a setup where after inserting a smartcard, the middleware needs some GUI interaction ...Show All

• Daikoku StateHistory is Null

  I'm looking at a StateMachineWorkflowInstance. I can see my currentstate and everything else except for the StateHistory. I've got both tracking and persistence turned on. Why would this property be null Is there something I'm missing I can reverse engineer the workflow history by looking at the activitytrackingrecords in the sqltrackingworkflowinstance but I'd prefer not to have to do that! I'm using a custom trackingservice, btw, if that helps. Thanks, John StateHistory only works with the SqlTrackingService. Thanks Jon. After all the work I've done learning about a custom tracking service - I'm a little miffed that I can't get statehistory. Is the standard approach to ...Show All

• Avi_harush TC23 - Problems undoing registry changes after installation rollback

  Hello, I'm trying to pass test case 23, and even if I finally got the installer to remove all the files that it installed (I had problems with reportengine.msm of Crystal Reports) after the rollback, I realized that it didn't undo the registry changes made during intallation. I think I read (in a post in this forum that right now I can't find) that we should make a little script to launch after rollback, where we could undo those changes manually. Well, this is what my imaging tool says about the registry changes after rollback: - Values added: 91.900 - Keys added: 97.700 - Values deleted and changed: 1000 Those are lots of changes !! I realized that our controls' registration information is still in the registry, even th ...Show All

• Thad213 Soundmax Audio Driver and Windows Longhorn Beta 1

  Hi, I have Soundmax driver installed on Windows Longhorn OS. When I use the sound recorder that comes with the OS (in the Startup->Entertainment section) and record through a microphone, my recording is okay. But if I use Wave out Mix as input pin  and try recording from Windows Media Player to the Sound recorder that comes with the OS, it does not record. It changes my setting to microphone when I start recording automatically. Also another difference I noticed between Windows Xp and Windows Vista is that mixer device option in the Volume Control of Windows Xp shows SoundMax Digital Audio and with Windows Vista it shows "Line in on SoundMax" and "Microphone on SoundMax", i.e. 2 options. Has anyone else encountered this ...Show All

  Hi! I am re-hosting the workflow designer. Is there any way to enable visual resizing of the activites in the workflow Thanks!     Hi, thank you for the help! It's great!   I have implemented the nextActivity property and the onConnected event. But, the workflow won't run in the correct order. If i drag activity1 and activity2 to the surface, and connect them with an arrow (activity1 = target and activity2 = source), activity1 still executes before activity2.

• ivods concept behind the condition " if (act.parent != null) " ??

  Why should we check the condition " if (act.parent != null) " in the Validate method of ActivityValidator Thanks & Regards, Chakri. Please, add this note to msdn ActivityValidator class :) If you don't then the validation is done when you are building the activity as well. In most cases you only want this validation to be done if the activity is being used in a workflow or another custom activity. The way you can get around the need for the null parent check is to use a C# class library project instead of a activity library since the validator is not called at compile time outside of a workflow project. ...Show All

• Rascal123 BUG in workflow designer

  Hi! In VS when you have workflow in design mode, and you select some CodeActivity ( doesn't really matter what you select ), you should be able to resize it...
