Silverlight C# webservices wait for process

Question

Hello,

I am developing a silverlight application, where I make use of webservices. The server is responsible for processing some text, get the phoneme info, convert to visemes, generate the audio and encode to mp3. A list of visemes and a path to the create audio file is returned. Then the audio is streamed to the client.

But now, I have a problem. I need for the server to wait for complete audio encoding creation. Sometimes, the audio is not ready, and it does not stream for the client. I 've tried thread.join but it has the same problem for long texts.

How should be the best way to resolve this issue ?

Thanks in advance

Hi there,

maybe I misunderstood your question, but I think this should not present a big problem as the async pattern should actually help you... My intuitive understanding of this scenario would be something like this:

myWebServiceClient.ProcessTextCompleted += (sndr, evnt) =>
{
  IsBusy = false;
  var url = evnt.Result.PathToCreatedAudioFile;
  PlayAudioFile(url);
};
IsBusy = true;
myWebServiceClient.ProcessTextAsync("abcdefg");

Maybe you could give a bit more information on why this is not working for your case.
