Hi Everyone,

I am trying to work with the Entered Text will be converted to Speech.I have a wsdl file and I created one web service with that.I able to call the SayAsync method by giving all parameter included with text but after my call to SayAsync it is not returning any result from objHttpBinding_SayCompleted and it is showing following error

Here is Error Message:

Target Invocation exception was unhandled by user code

An exception occurred during the operation, making the result invalid. Check InnerException for exception details.

Here is Stack trace:

at System.Web.AspNetSynchronizationContext.CallCallbackPossiblyUnderLock(SendOrPostCallback callback, Object state)

Here is My code:

protected void btnvoice_Click(object sender, EventArgs e)
            VFHTTPBinding objHttpBinding = new VFHTTPBinding();
            objHttpBinding.SayCompleted += new SayCompletedEventHandler(objHttpBinding_SayCompleted);
            objHttpBinding.SayAsync("sssssssss", objTextInfo, objvoiceinfo, objaudioinfo);
    private void objHttpBinding_SayCompleted(object sender, SayCompletedEventArgs e)
        lblmessage.Text = e.Result.ToString();

Is there any wrong with my code ,Thanks in advance if any can reply...
