• Audio and Video Development Protected Content (PMP) and tee node

  Is it possible to play a protected media file in a topology using the tee node. I modified the ProtectedPlayback sample and I get MF_E_TOPO_UNSUPPORTED error after setting the topology. Thanks! Actually I was talking about a protected WMA file. It plays fine in WMP11 and in the ProtectedSample as is. But not when I insert a tee node into the topology. Thanks ...Show All

• Audio and Video Development About ShutdownObject() of IMFActivate.

  I have made OriginalSink and implemented IMFActivate, I could create instance of mySink in the PMPProcess. When the PartialTopology was sent to PMPHost, ActivateObject() of mySink(IMFActivate) was called from PMPSession.  And then I have two questions.  1. Although  ActivateObject() of mySink was called from PMPSession, ShutdownObject() of       mySink was not called from PMPSession  . 　　This is why 2. When PMPSession was called Shutdown(), Shutdown() of mySink was called synchronously. 　　And mySink shut down myStreamSink. 　　Is there any problem about that ShutdownObject() has never been called   Hi Becky! Thank you for your answer! I ...Show All

• Architecture Pattern to choose

  Hi, I have worked for several years as a developer/analyst and now I am trying to improve my design knowledge... I hope my question is right for this forum... I have a very large XML file (in excess of 350Mb and can probably get even bigger) that contain some hierarchical data (nested elements). I also have the XML schema that specifies the allowed hierarchical relation between the various elements (well, a schema…). This imply, for performance reasons that I have to use a XML reader of some type. Writing a "prototype" I ended up with a class that contains the reader and has several HandleElementXXX function that work on the reader… Starting from a main loop (while (!reader.EOF) the reading/parsing is delegate ...Show All

• SQL Server Is SQL Server CE really the solution?

  Hi,   So far, with other programming platforms, I used to have the facility, embedded within application .exe, to:        1- Interface with already existing "multi-user" database (ex: Oracle, Access, etc.)        2- Create/access "local"/"Single-User" files for processing purposes.  (try to minimize network trafic...)   So far, I've read a lot about SQL Server products (SQL Server, Sql Server Express, SQL Server CE), at least all articles I could find, and would like to have your opinion on what would be the best approach        1- What SQL version to use for "multi-user" databases &n ...Show All

• .NET Development SMTP Errors - unable to trap SMTP exception

  I am trying to send email using the .net 2.0 SMTP client asynchronously using the SendCompletedEventHandler to see if the email is sent (the example is found in MSDN) SmtpClient c= new SmtpClient(host); c.sendCompleted += new SendCompletedEventHandler (mymethod); MailMessage m = new MailMessage(from,to); (from and to are valid e-mail address) c.SendAsync(m,userState); Then method mymethod will get called and I check to see if there is an error or a cancelation if not I know it is sent . However I am not able to trap the SmtpExceptions (if any ) using this asynchronously method if i use just: c.Send(m); I am able to trap the SmtpException (if any) Any ideas why -jawahar ...Show All

• Visual FoxPro How to fix grid headings?

  Can we do that It does not help if I set: AllowHeaderSing=.f.   I think you meant AllowHeaderSizing. If you set it to .F. header height is not allowed to change.

• .NET Development unable to process request -> No connection could be made because the target machine actively refused it.

  Hi there, I have a thin client (windows) on the front and some web services on the server. When we have multiple simultaneous connection hitting the service we are getting this error: Server unable to process request -> Unable to connect to remote server -> No connection could be established as the server actively refused it. It only happens for 3 or more connections simultaneous using the server. Could this be a Windows license limit issue on the server, not allowing users. When I connect alone there is no problem the client talks to the server just fine (which reinstates the connection and port settings are all fine). Since the connection is over http, I dont see a firewall issue too. Please comment on what could be causin ...Show All

• Smart Device Development Supplying name for incoming call

  Hi, when a call comes in, the device's phone application will - somehow - try to display the name of the caller by using the addressbook. How could I add my application as a primary resource for that, i.e. how can I supply the caller's name for an incoming call (WM2003/WM5 both PPC and SmartPhone) I've been looking at the RTC documentation, but it is unclear whether this will work. Thanks in advance for any pointers, Daniel Hi Daniel The registry notification APIs are new to Windows Mobile 5.0. To support Windows Mobile 2003 as well you'd need to monitor the GSM TAPI line directly.There are a bunch of forum thread dealing with this.

• Visual Basic Is it possible to create a delagate that points to a property of a class?

  Hello, I am trying to create a delagate that points to the property of an object. I am trying to create a class that can be created from a number of different types of objects that contain the "Item" property. Many classes in the .NET Framework support the Item property, but there is no interface that defines this property, so I cannot seem to figure out how to make a generic method that will accept a number of different object types. Here is a sample of my code: Class SomeClass Private Sub New() End Sub Public function FromDataReader(ByVal Reader As SQLDataReader) As SomeClass Dim Value As new SomeClass() Class.[propertyname] = Reader.item([ItemName]) Return Value End Function Public function FromDataRow(ByVal ...Show All
