Email counter not working !!!

[email protected] · February 1st, 2009, 10:33 AM

Goal : Developing and ASP.NET 2.0 based mail sending application for sending mass emails (whihch could have attachements also so need a file uploader on the aspx page), which will be send one by one, i.e no CC and BCC.The aspx page should be able to display number of emails successfully send for any given moment.
Approch Implemented : I am using a page level variable which get incremented on each successful mail send. This variable is passed to a local WebService( WebService is inside the application). From the aspx page I am calling another WebService which holds the value of this counter variable along with current time using Javascript and AJAX(Script manager , Services , ServiceReference) every 5 seconds and updating a div tag on the page with the value.
Issue : The counter and time is working fine till the page is not posted back. As soon as i provide the necessary valuesfor the mails ( body text , contacts list(text file based), from address etc) and click a button to post the data to server for processing the counter stops, but the mails keep getting sended, the counter once again starts working as soon as the job of sending mails finishes That is the page is fully posted back.

Kindly suggest me a solution and it would be gr8 if a small working code for the same is provided.

Following is the aspx page I am using :

Code:

<style type="text/css">
function GetSuccessMail(param)
        {  
            var testBool = param;
            NavatarService.MailsSent.SuccessMails(testBool, OnWSRequestComplete,OnWSRequestFailed);               
        }
        
        function OnWSRequestComplete(results)
        {
            if (results != null)
            {
                var lbl = document.getElementById('SuccessDiv');
                lbl.style.fontWeight = 'bold';
                lbl.style.color = 'lime';
                lbl.style.visibility = 'visible';
                lbl.style.width = '100%';
                lbl.value = results;             
            }
        }
        
        function OnWSRequestFailed(error)
        {              
            alert("Error getting hints");
        }
        
        
        setInterval ( "GetSuccessMail(true)", 1000 );

I moved yout post to this forum, I don't think it was about the book where you posted it. Also, you might try editing your post and wrapping your long code lines near the end so it's easier to read.
