Al salamo alykom,
Hi Mohammed how are you,
Great to have a target to achieve, great to insist on, but not great to make your target to be another Microsoft fan!!

I don’t hate Microsoft, or love it, But Technology != Microsoft any way.

Try to look outside Microsoft’s circle, there is yet another world.
What i get annoyed from some of friends who are MS fans that, they don’t see more or less than Microsoft. but again, there is a garden world outside MS barriers. Just try to discover that world.

Best Wished from Egyptian, arabic, Moslem brother,

Have fun.

Thanks, Hwedy
You were so great
But, I don’t prefer Microsoft all the time.
I think Microsoft is taking the approach “pay-as-you-go,” and I hate that approach.
I love Linux too much, also I prefer some other Microsoft products.
But, sure I’m a great fan of Microsoft, and of course other technology industries

Please provide more details (e.g. InnerException).

This should work fine:

private void button1_Click(object sender, EventArgs e)
{
    try
    {
        SmtpClient server = new SmtpClient();
        server.Credentials =
            new System.Net.NetworkCredential(&quot;xxxx@gmail.com&quot;, &quot;password&quot;);
        server.UseDefaultCredentials = false;
        server.Port = 25;
        server.Host = &quot;smtp.gmail.com&quot;;
        server.EnableSsl = true;
        server.DeliveryMethod = SmtpDeliveryMethod.Network;

        MailMessage message =
            new MailMessage(&quot;xxxx@gmail.com&quot;, &quot;yyyy@rediffmail.com&quot;);
        message.Body = &quot;i love u&quot;;
        message.Priority = MailPriority.High;
        message.Subject = &quot;my own mail ide&quot;;

        server.Send(message);
    }
    catch (SmtpException SE)
    {
        MessageBox.Show(SE.ToString());
    }
}

1st. You you should set the SmtpClient.DeliveryMethod to SmtpDeliveryMethod.Network

2nd. Never ever catch Exception, ApplicationException, or SystemException. You should handle that specific exceptions.

I have a question about your SimpleRec for C#. I can run the sample on one of my Win 7 Ultimate computers but not the other. I get the following error: No wave device is installed that can record files in the current format….” I uninstalled all my audio devices and reinstalled. I have applied all Microsoft updates and Dell BIOS, etc…updates. Any thoughts why this may be occuring?
