    - TC32: Inconsistent WER behavior When we inject AV into our C# app, we see that the app crashes as expected but we do not get two events in the event log as specified in the test case. We get the "Application Error" everytime.However we find that we do not get t he INFORMATION message with source as WER sometimes, but not everytime we inject AV to the app. We find the behavior is inconsistent. We have not done anything specific in the application for handling this. We just let the app crash and let the OS take care of WER. The "Problems & Solutions" is set to automatically send problem reports for all users. We are not sure what are we missing. Or is there a way we could handle this in the app and not depend on OS settings. Thanks. Tag: Workflow designer control

    - instanceOwnershipDuration and websites I have an IIS based website using a workflow. It contains delays of a variable length in order to make timeouts expire at a fixed point every week, and the workglow. On the whole, it seems to be working, but I want to confirm the workflow persistence time settings. I'm happy with a delay resolution of 1 minute, so I assume that setting the loadingInterval to 1 minute will be fine for this. However, I'm not sure what the appropriate value for instanceOwnershipDuration should be. Nominally, the work done in the workflow takes negligible time, although in fact it occasionally sends email, which can take a few seconds. Should I be setting instanceOwnershipDuration to safely longer than the email interval, here What happens if two pages referring to the same wortkflow are loaded in quick succession - does the second one fail because the persistence store records that the workflow is owned by another process, or does it wait for the workflow to be released (and for how long), or what I'm also seeing an occasional error message of the nature 'Queue 'Message properties: ...' is not enabled'. I can't quite figure out what circumstances cause this to happen, and I wondered if it might be related. Tag: Workflow designer control

    - AVI Playback time is not correct Hi there, I have an application that can use USB webcams to feed the video and record the video in avi file with/without compression, the filter graph uses Intel Indeo Video 5.10 or Microsoft Windows Media Video 9 compressor. Now I am trying to get the video from IP camera, there is no problem to preview the video from IP camera and record it into an avi file. Everything is fine without compression if I record the video and playback with Windows Media Player. However, the playback time is not correct if I record the video with compressor above and play it back with WMP. For example, for a 10 seconds video from IP camera, with the frame rate 1, 10 and 30 fps, the recorded frames in avi files are 32, 30 and 34, so when playback those files, the time become 32, 3 and 1 second. My source filter and output pin class are drived from CSource and CSourceStream. I tried many ways, but still have no idea what is wrong. Please help and your input are much appreciated. Thanks in advance. W. Tag: Workflow designer control

    - Active Movie Window appearing while using Video Mixing Renderer 9 in windowless mode Hi everybody. I encountered a problem while using the Video Mixing Renderer 9 to display video file and camera. In fact, each time I change the video file to play, I destroy the graph by that I mean I remove all the filters in the graph. Then, I build a new graph again including the Video Mixing Renderer in it. The problem is that it works fine for a moment but while using about 10 times this method, my video is not shown and there is an Active Movie Window which appear and displays nothing in it. I haven't find out what was the problem. Could somebody help please Thanks in advance Tag: Workflow designer control

    - Polling does not work on Dual Core To pass trough the complex synchronisation mechanism in a multithreaded application and still have the look and feel of such an architecture, the easiest way is to have a single process application and distribute the processor to several inner tasks. It looks like rewriting Windows Scheduler but indeed it is just a 200 line assembly program plus some Wait and Signal in a higher level language. Doing that get ridd of the preemptive nature of Windows and synchronizing such inner tasks is quite simple (Comunicating Sequential Processses). The designing constraint is that the Window process should never block itself on a waitng function because it woul block all the inner tasks. The documentation of SDK indicates every where that this solution was planned by the designers of Windows. The GetMessage function in the message loop can be substituted by the non blocking PeekMessage functions. The OverlappedIO mechanism needs a synchronisation point that can be done with the non blocking SleepEx function giving a 0 delay. In Winsock, the Select instruction to test for the success of a Connect can be non blocking giving a zero delay. And it works fine but the Task manager indicates a 100% use of the process. This is purely satistics because in parallel you can play a movie with no noticeable difference. On a Intel Dual Core there exists a mechanism to lower the processor frequency. In that case, the frequency is not lowered, the processor heats up and the fan start pushing air, making the polling solution unusable. Question What is the instruction to lower the frequency of the processor in a Dual Core Tag: Workflow designer control

    - TreeView TVM_SETITEM message I'm writing a C# application that uses NTBACKUP utility to backup and restore, I successfully backuped up using NTACKUP command line but command line doesn't support restore as written in NTBACKUP docs. Now to restore I'm running NTBAKUP process from my application and controlling it by sending messages to its window using Win32API. I've done all of the things but stuck in a TreeView control where I've to check its checkboxes to select items to restore in the bacup catalog. I even able to expand tree, get the specified tree node and selected it but couldn't able to check its checkbox, when I send the "TVM_SETITEM" message to TreeView to check the TreeView item the NTBACKUP utility crashes with the message "An unhandled win32 exception occured in ntbackup.exe". The code I'm using to check the TreeView checkbox is taken from a Microsoft knowledge base article http://support.microsoft.com/kb/313134 and its correct.

    - Vihang's Re-hosting Workflow Designer tool implementation issues?? Vihang, I have downloaded the Re-hosting Workflow Designer tool sample you created. I have XOML only State workflow that references assemblies (does not use x:Class attribute in the root node) and uses namespaces with namespace aliases for specific activities that are used in the XOML only workflow. Can you please modify this example to work with XOML only state workflow that can reference namespaced references (for codebeside and for coded activities). Below is the xoml file that I need to load, update, and save. It would also be nice if I could compile it without errors. The main issues are referencing namespaces instead of code-behind class and activities (i.e., activities need to be referenced via namespaces).

    - Is it a bug of socket on vista? my program's work flow: my program have two part: server and client client(vista) broadcasts packets(255.255.255.255) to discover server, then server reponses some information to client. If the server(not vista) is in the same network section with client, it sends unicast packet to client; and if in different section, it broadcasts(255.255.255.255) inforamtion to client. they works very well when the server and client are in the same network section, but in different section, the client can't receive the broadcast packet. And on XP/2000, the client can work well in these two case. my code about the client : sock = socket ( AF_INET, SOCK_DGRAM, 0); nReturn = setsockopt ( sock, SOL_SOCKET, SO_BROADCAST, (CHAR *) &bBroadcast, sizeof( BOOL ) ); if ( SOCKET_ERROR == nReturn ) { closesocket(sock); return FALSE; } dsUdpCli.sin_family = AF_INET; dsUdpCli.sin_addr.s_addr =INADDR_ANY; dsUdpCli.sin_port = htons ( 0 ); nReturn = bind ( sock, (SOCKADDR *) &dsUdpCli, sizeof ( SOCKADDR_IN ) ); if ( SOCKET_ERROR == nReturn ) { closesocket(sock); return FALSE; } nTemp=RECV_BUF; setsockopt(sock,SOL_SOCKET,SO_RCVBUF,(char *)&nTemp,sizeof(int)); dsUdpServ.sin_family = AF_INET; dsUdpServ.sin_addr.s_addr = htonl ( INADDR_BROADCAST ); dsUdpServ.sin_port = htons ( 0x868a ); nReturn = sendto ( sock, szMessage, nTemp, 0, (SOCKADDR *) &dsUdpServ, sizeof ( SOCKADDR_IN ) ); if ( SOCKET_ERROR == nReturn ) { closesocket(sock); return FALSE; } FD_ZERO(&temp_set); FD_SET(sock, &temp_set); while(1) { if(select(0, &temp_set, NULL, NULL, &temp_timeout) == 0) { break; } nSize = sizeof ( SOCKADDR_IN ); nReturn = recvfrom ( sock, szMessage, MAX_RECV_LEN, 0, (SOCKADDR *) &dsUdpCli, &nSize ); if ( SOCKET_ERROR == nReturn ) { return FALSE; } printf("Discovered a server.\n"); } closesocket(sock); Tag: Workflow designer control

    - PlaySounds fails under Vista I have a pretty straight forward call that I've used for years but apparently isn't working on Vista.

PlaySound(MAKEINTRESOURCE(IDR_WOOF),hInst, SND_RESOURCE | SND_SYNC | SND_NOWAIT); For any of you who use WinPatrol, if you have Vista you may have noticed that Scotty doesn't bark anymore when there's a change detected.

    - Self-updating application I'm hoping someone here can give me ideas, or at least point me in the right direction. Our application (under XP) is capable of downloading and installing updates to itself. An XML manifest is stored on the server, which outlines all the updated files. However, since the format of this file might need to change over time, the application itself isn't qualified to read this file. Instead, it uses a DLL. The DLL is always up to date (i.e. able to read the file manifest) because the application first downloads the latest version of the DLL from the server. It then invokes code in the DLL, which processes the manifest, creates a list of files that need to actually be downloaded, and returns control to the application. Next, the application needs to exit, and allow the files to be installed (one of which is invariably the application itself). This process is handed over to another exe, which the application downloads the latest version of as well. The installer reads the manifest, examines the downloaded files, installs everything, and then re-launches the main application. All of this is working under XP. When it comes to Vista, we obviously are going to encounter some challenges. The primary problem is that the application, which must run as a standard user, has to somehow download a DLL and an EXE, and place them into CSIDL_PROGRAM_FILES_COMMON. Is there any way to do this (At this point I'm just assuming that I wouldn't be able to download them to anywhere outside of \Program Files and still be able to execute them.) Also, if I'm able to get the update installer exe written somewhere, will the application (which is currently marked as asInvoker) be able to execute the installer, which is marked requireAdministrator Thanks, Dave Tag: Workflow designer control

Sometimes things work absolutely fine. My workflow starts with HandleExternalEvent Activity which waits for the pageSubmitted Event which I m raising from the UI. My code from the UI goes like this. ................ ..................... WorkflowRuntime workflowRuntime = new workflowRuntimeServices .SetRuntimeService(); ExternalDataExchangeService exSvc = new ExternalDataExchangeService (); workflowRuntime.AddService(exSvc); svc = new Service (workflowRuntime, typeof ( MyWorkflow )); exSvc.AddService(svc); //workflow call svc.RaisePageSubmittedEvent(args); //code after workflow call in the page ................ ..................... The workflow service class looks like this public class Service : IService { public Service( WorkflowRuntime workflowRuntime, Type activatingWorkflow) { _wfruntime = workflowRuntime; _ActivatingWorkflow = activatingWorkflow; } public event EventHandler < CSDSubmittedEventArgs > PageSubmitted; public void RaisePageSubmittedEvent(Args args ) { _wfruntime.CreateWorkflow( this ._ActivatingWorkflow, new Dictionary < string , object >(), InstanceId).Start(); // Create the EventArgs for this event PageSubmittedEventArgs e = new PageSubmittedEventArgs (InstanceId); e.Data =args; // Raise the event if ( this .PageSubmitted != null ) this .PageSubmitted( null , e); } // This is how I am creating WorkflowRuntime object with persistance service. public static class workflowRuntimeServices { public static WorkflowRuntime SetRuntimeService() { try { workflowRuntime = new WorkflowRuntime (); workflowRuntime.AddService( new SqlTrackingService (connectionString)); workflowRuntime.AddService( new SqlWorkflowPersistenceService (connectionString, true , new TimeSpan (0, 0, 3, 0, 0), new TimeSpan (0, 0, 0, 1, 0))); workflowRuntime.AddService( new DefaultWorkflowSchedulerService ()); workflowRuntime.StartRuntime(); AutoResetEvent waitHandle = new AutoResetEvent ( false ); workflowRuntime.WorkflowCompleted += delegate ( object sender, WorkflowCompletedEventArgs e) { waitHandle.Set(); }; workflowRuntime.WorkflowTerminated += delegate ( object sender, WorkflowTerminatedEventArgs e) { waitHandle.Set(); }; workflowRuntime.WorkflowLoaded += new EventHandler < WorkflowEventArgs >(workflowRuntime_WorkflowLoaded); workflowRuntime.WorkflowIdled += new EventHandler < WorkflowEventArgs >(workflowRuntime_WorkflowIdled); workflowRuntime.WorkflowPersisted += new EventHandler < WorkflowEventArgs >(workflowRuntime_WorkflowPersisted); workflowRuntime.WorkflowUnloaded += new EventHandler < WorkflowEventArgs >(workflowRuntime_WorkflowUnloaded); return workflowRuntime; } catch ( Exception ex) { return null ; } } static void UnloadInstance( object workflowInstance) { WorkflowInstance instance = ( WorkflowInstance )workflowInstance; try { instance.Unload(); } catch ( Exception ex) { ErrorLog .LogFilePath = strLogFile; bReturnLog = ErrorLog .ErrorRoutine(ex); } } static void workflowRuntime_WorkflowIdled( object sender, WorkflowEventArgs e) { ThreadPool .QueueUserWorkItem(UnloadInstance, e.WorkflowInstance); } static void workflowRuntime_WorkflowUnloaded( object sender, WorkflowEventArgs e) { } static void workflowRuntime_WorkflowPersisted( object sender, WorkflowEventArgs e) { } static void workflowRuntime_WorkflowLoaded( object sender, WorkflowEventArgs e) { } } When I debugged the code I could see that once the point of execution reaches the following line of code, this .PageSubmitted( null , e); nothing happens,it just goes to the next lines in the sequence but, sometimes the point of execution goes inside the workflow code.ie. to the handler for HandleExternalEvent activity. Can anyone give me some guidance as to why this happens. Thnx in advance, Suja Tag: Workflow designer control

    - Bytes transferred by File Source (Async) Filter Hi all, I have a graph containing File Source(Async) filter connected to InfTee Filter. I want some specific number of bytes to be transferred from File Source(Async) filter to InfTee Filter. How can I achieve this behaviour How to specify the buffer requirements I would be grateful if somebody could help me in this. And, Do you know, how many bytes will be transferred (from the output pin) by the File Source filter by default Thanks in advance!!! Tag: Workflow designer control

    - exposing webservice Hi, My workflow has a webservice input activity where it will receive a string from the user and then return the result through wb service output and then will receive 2 strings from the user again but it shows me the error below when I called the second method System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.InvalidOperationException: Current session has no workflow instance associated with it. Send activation message to start new instance in current session. at System.Workflow.Activities.WorkflowWebService.GetWorkflowInstanceId(Boolean& isActivation) at System.Workflow.Activities.WorkflowWebService.Invoke(Type interfaceType, String methodName, Boolean isActivation, Object[] parameters) at LibraryManagement.Workflow1_WebService.GetLoginDetails(String username, String password) in C:\Documents and Settings\claudia\Definicoes locais\Temp\zky4brg1.cs:line 47 --- End of inner exception stack trace --- I have an interface called: interface ISearchForBook { string GetSearchOption(string option1); // to get title name from the user string GetLoginDetails(string username, string password); //to get username and password from the textboxes } The code that I used to called the second method is like this: LibraryWebService.Workflow1_WebService h = new LibraryWebService.Workflow1_WebService(); result = h.GetLoginDetails(textBox1.Text, textBox2.Text); --> this is the line that gives me error MessageBox.Show(result); I already tried using this code below but still give me the error: LibraryWebService. Workflow1_WebService h = new WindowsApplication1.LibraryWebService. Workflow1_WebService (); h.CookieContainer = new System.Net. CookieContainer (); System.Net. Cookie wfId = h.CookieContainer.GetCookies( new Uri (h.Url))[0]; System.Net. Cookie _Cookie = new Cookie (wfId.Name, wfId.Value, wfId.Path, wfId.Domain); h.CookieContainer = new CookieContainer (); h.CookieContainer.Add(_Cookie); Can someone help me Cheers!

Hi ,

I am trying to host the workflow designer on a web page.

I have made a winform Control that hosts the designer.
When i rehost this control on a winForm it works fine.

When i host this Control on a webpage it doesn't show on the page.
Can anyoneguess what might causing the problem Is there some example on the web that shows how to do this
I have a feeling that security is not an issue because i have add the site as a trusted site on my IE and if i remove the designer from the winform control and add a label and button to the control it shows up on the web page.

thanks
Sonali

It is a security issue - with .NET code-access security. You'll have to add that website to a code group that provides fulltrust persmission set.
