• Avi120 Can you instantiate a different Workflow by using a Custom WorkflowLoaderService?

  I'd like to get the Workflow from an assembly file and dynamcially instantiate it by creating a custom WorkflowLoader Service. I've tried this: WorkflowInstance instance = workflowRuntime.CreateWorkflow(typeof(ProxyWorkflow)); -- where ProxyWorkflow is nothing more than a blank activity (I've also tried making it a blank SequentialWorkflow) and in my custom WorkflowLoaderService, I try this: Activity workflow = (Activity)Activator.CreateInstance(_workflowType); return workflow; --where _workflowType is a SequentialWorkflow loaded from an Assembly file However I get this error: System.InvalidOperationException: Can not create workflow definition. WorkflowL oaderService has returned an object whose type does not match 'WorkflowClasses.P rox ...Show All

• Tovdb DWM Live Thumbnail Capturing?

  Hello all! Is there a way to capture the live window content we can get from a DWM Thumbnail As I understand it, the live thumbnail is slapped on the window area during the composition process, so any capture methods would require DWM APIs exposing said functions. Perhaps it would be a good idea to have a function that returns a HBITMAP for saving to disk, or saves the file directly given the path and file type. It would be useful to have such an API for screenshot programs: select a window and have a screenshot taken, including the transparent frame regions that DWM gives to thumbnails. Thanks, Karl These are both good requests, but unfortunately we won't be able to accomodate them on ...Show All

• Batikit Persistence and Serialization Error

  I have recently upgrade to the June CTP. I am experiencing an odd error when using the delay activity. Using SQL Profiler I can see that the call to "InsertInstanceState" passes a "status" paramter value of 3. What exactly is 3, is there a reference doc somewhere I can download to see all statuses In addition, the info parameter has the text, 'System.Net.Mail.Attachment'' in Assembly ''System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'' is not marked as serializable. I am using the EmailActivities provided on the WF site. I compiled them in VS2005 and added the activity to my IDE. Once my workflow completes the delay is supposed to email me. This never happens. Rather my workflow hits the d ...Show All

• Mosesm fatal error LNK1104: cannot open file when building a .dll file on Window Vista

  Hi all, i'm a newbie and i have small trouble with Window Vista. I have a small program which will create a .dll file in C:\windows when i build it.Everything is ok with Window XP or Win 2000 but when i rebuild my program on Window Vista, i got an error: "LINK : fatal error LNK1104: cannot open file "c:/windows/myfile.dll"" I used Visualstudio 6.0 to build my program.

• SimonS_ unit test problem

  Hey! I'm about to start a new software project and are thinking of using unit testing. I have read some atricles about this and it simes like TransactionScope it the way The ide is to run a unit test in a searten transaction context, this means that all database(sql2000) operations that executes with in the transaction context will enable rollback. This will also make it possible to run tests at the same time on diffrent computers but with only one database. I have created a test project that works against another MS SQL 2000 server in the network as follows: This class is located in a special test project. userTest.cs [TestMethod()] public void createUser() { string firstName = "Olle" ; string lastName = "Sve ...Show All

• Kanchan Have to use CorrelationAlias attribut for all methods within the ExternalDataExchange interface?

  I'm currently use CorrelationAlias for some of methods of ExternalDataExchange interface, but once I got compiling error for all methods that did not specify CorrelationAlias. Is that true as long as I specify CorrelationParameter on an ExternalDataExchange interface, then I have to specify CorrelationAlias for all methods Is there any way I can do it partially I have so many methods that don't need correlation at all. What's the performance/memory cost extra CorrelationAlias Thanks. Yes - if you use it on one method or event - you must use it on all of them. There isn't much perf overhead really - in fact probably none at all since even when you don't use those attributes - the communication infr ...Show All

• Mike Brown Using smartcards in a service - SCardAccessStartedEvent

  Dear all, Migrating our core development platform to Windows Vista, one of our Windows services using smartcards is failing. We have debugged the problem and found that the event provided by the function ScardAccessStartedEvent does not receive notification. This event is supposed to signal when the SmartCard Resource Manager starts. As we have a WaitForSingleObject(event,INFINITE), the service hungs. Testing the same service as an ordinary executable ( registering with -regserver ) I can see it works properly. In XP it works properly both as an executable and service. I have read something about Service Hardening in Vista and I guess it may be caused by privilege reduction. So, I've created some code to enumerate the existing ...Show All

• simmons Help me set up .NET 3.0 development on virgin PC

  Oh, the combinations I've tried...! I've got a new PC, fresh install of XP Pro SP2. I ran through the recommended steps with the goal of running the WCF Getting Started sample project, but have failed to get it to run without error. I suspect an IIS configuration problem, but will start all over again from the beginning. Here's the steps I'm going to take (using the June CTP) in yet another attempt. Can anyone make corrections 1. Install IIS 5.1 (from Control Panel | Add or Remove Programs | Add/Remove Windows Components) 2.

• CFIG PC games + 8800GTX + Vista compatibility? (need help ASAP actually)

  I need to get a new computer within the next few months, and I am rather concerned that I will not be able to play certain games decently (if at all!) with the nVidia 8800GTX and Vista that I plan on getting with it (Alienware). As a result I've been looking on the net for places where I can get a sense at how well the two of these work together after the first official drivers have been released for the 8800GTX for Vista. In particular, I am hoping to hear from you guys that you all have experience playing games such as (ones I play) Dawn of War, Civilization 4, City of Heroes/City of Villains, World of Warcraft, Battlefield 2, and Unreal 2: XMP (that one's a bit obscure though). At least as far as Dawn of War is concerned, I heard ...Show All

• omrivm Temporarily Registering ActiveX Control

  We have an application that runs off a CD and uses an ActiveX control stored in a DLL (or .ocx, does not really matter). The CD is to be run on the client's computer, and the client may not necessarily have administrator privileges. Is there a way to temporarily register the ActiveX control for the duration of the application Basically do something like "regsvr32" on the DLL while the app is running, and "regsvr32 /u" on exit. Basically we would like to force the ActiveX Control (identified by a CLASSID) to load from a particular DLL, and that DLL is on the CD. In case you are still interested: We actually took a different route. I simply loaded the needed ActiveX DLL using Load ...Show All

• Abhishek_SE StateMachine invoke SequentialWorkflow

  Hi together, I am using a state machine workflow which invokes another sequential workflow. The sequential workflow gets called but after the sequential workflow has finished, the parent workflow (which is a state machine) switches to the completion state. Example: Sequential Workflow ^ | State A ---> State B ----> State C ----> Completion State As you can see in the sample "State B" invokes "Sequential Workflow". And now when the sequential workflow gets finished, the parent state machine switches to the completion state instead of "State C".
