HttpWebRequests + Window service.

[mike55]

Hi

 

My windows service is capable of connecting to a third party service provider, http://www.clickatell.com in this case. I am using the third party to send out a number of sms text messages in the event that another service goes down or fails to reply within a specific timeframe. I am using a List<string> to store the list of number that I am sending to, and passing my message as a string.

 

The problem that I am having is that when I go to send the last message, I get a timeout exception. I have tried to get the service to sleep for 15 seconds before sending each message, but this has had no effect.

 

Here is the code that I am using:

       //Queue the message to the EMS personnel, and send it.
       private static void QueueEMSMessages(ClubtextMonitor.Modules.MonitorConnect myConnection, String sysMessage)
       {
           //Get the person who is to receive the message.
           List<string> msgDestination = myConnection.GetTechSupport();

          //Create the message and send it to the support person.
           foreach (string ems in msgDestination)
           {
               try
               {
                   ClubtextMonitor.Modules.Message errMessage = new ClubtextMonitor.Modules.Message(sysMessage, ems);
                   //Wait for 15 seconds before sending the message
                   System.Threading.Thread.Sleep(15000);
                   errMessage.sendMessage();
               }
               catch (Exception ex)
               {
               }
           }
       }

//Allow the client to send the message for the user.
       public bool sendMessage()
       {
           //Parameter for storing the send message credentails
           string[] credentials;

           //Get the credentials necessary for sending the message.
           ClubtextMonitor.Modules.MonitorConnect connection = new ClubtextMonitor.Modules.MonitorConnect();
           credentials = connection.GetCredentials();

           bool outputValue = false;

           //Ensure that the correct number of credentials have been supplied.
           if (3 == credentials.Length)
           {
               outputValue = true;
               WebRequest objRequest;

               //The web request to be sent to the message gateway.
               string msgRequest;
               msgRequest = "http://api.clickatell.com/http/sendmsg?user=" + credentials[1].ToString() +
                                   "&password=" + credentials[2].ToString() + "&api_id=" + 
                                       credentials[0].ToString() +"&to=" + msgDestination 
                                           + "&text=" + msgText;

               //Send the message to the individual on tech. support.
               objRequest = System.Net.HttpWebRequest.Create(msgRequest);
               objRequest.GetResponse();
           }
           else
           {
               outputValue = false;
           }
           
           return outputValue;
       }

Not a clue if this will help but you are creating a response object for each call of the sendMessage method that you are never using - if you try either calling response.Close() before exiting the method or just not creating the response does that fix the problem?

Thanks for the reply PlausiblyDamp, I should have mentioned that my two methods are located in two different objects so I need to createa response object. Based on what you are saying, I should locate this line to outside the foreach loop and only create one object instead of three. I will also try the response.Close() option.

 

Again many thanks.
