    - Adding variable to an ActiveX control Hello, In VC++6.0 when I add a variable to an Active X control the the MFC wizard automatically generates a wrapper class for the control, and proceeds to let me create a variable for it. In VC++2005 when I add a variable to an Active X control the MFC add member variable wizard shows: Run Time Error has occurred. Line 1211 Error: Object Required. When I choose the debug option the best I can tell is that it gets to a statement that says: "Cannot Access ActiveX Control type Library" "Check to see if the .rc file is open in another editor" which it is not as far as I can tell.

    - how to add sqlpersistance service and how to use handle external events when workflow is published as webservice I got a workflow that is activated by a WebServiceInput, calls some other WebServices during it's runtime and responds with a WebServiceOutput to the original caller - I guess a most common scenario for these kind of web services. But how do I handle errors in here The web services invoked can under circumstances return a SOAP exception containing a detailed error description. I do not want to handle these exceptions in my workflow, but just forward it to the original caller of the workflow. So I thought I just put in an exception handler for SOAP exceptions (or exceptions in general) and send that exception with WebServiceFault back to the caller. Nice thought, but that does not work, because the WebServiceFault as a special kind of WebServiceOutput complains that: Error 56 Activity 'webServiceFaultActivity1' validation failed: WebServiceOutput activity 'webServiceOutputActivity1' also refers to WebServiceInput activity 'webServiceInputActivity1'. So what is the trick or workflow pattern here to get the fault response to the caller in case of an exception Tag: AVI Playback time is not correct

    - Either method could not be found or method signature does not match the delegate type. Hi have created a custom activity that raises an event that is a generic but when I try to use the activity in a workflow I get the following error Method <method name> could not be resolved. Either method could not be found or method signature does not match the delegate type. My project still compiles and the event is still fired but I would really rather not have the bang over every instance of the activity. Here is an example of the implementation **Activity Code [ MergableProperty ( false )] public event EventHandler < ResponseActivityRespondEventArgs > Respond { add { base .AddHandler(RespondEvent, value ); } remove { base .RemoveHandler(RespondEvent, value ); } } **Workflow code private void validateRequestResponseActivity_Respond( object sender, ResponseActivityRespondEventArgs e) { Console .WriteLine( "HI" ); } Tag: AVI Playback time is not correct

    - Serializing a Generic Collection to XOML Hi. I was wondering whether the limitation on serializing an Activity property that is a generic collection (e.g. List<string>, Collection<string>, etc) still stands. I've found a post addressing this issue ( http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=115333&SiteID=1 ) saying the problem might be solved in beta 2.

    - Disappearing Text in Windows Vista Shapid, Thankyou so much. This fixed my problem. Everywhere that I had a TextBox within a SplitContainer, I simply set the BackColor of the SplitterPanel to a non-transparent color. This fixed my problem! This seems like a serious Vista bug. Microsoft should fix this. I don't know how you figured this out, but your solution is a god-send for me. Regards, JWTK Tag: AVI Playback time is not correct

    - Problems with Web folders (WebDav) in IE7 Not sure about Vista, but Web Folders won't open with IE7 and XP, unless you have Office 2003 installed. When you try to open one, you get an error message that says Windows cannot find бо(null)бп. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search. It seems that IE7 isn't properly passing the path to Explorer, and instead is passing (null). For some reason if you have Office 2003 this doesn't seem to be an issue. Sorry if this is the wrong place to post this... it's the only place I've seen the issue with Web Folders and IE7 mentioned online yet. Tag: AVI Playback time is not correct

    - 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: AVI Playback time is not correct

    - 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: AVI Playback time is not correct

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.

    - 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: AVI Playback time is not correct

    - 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.

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.
