I wrote this class:

<br />
  public class Send_Mail<br />
    {<br />
    <br />
        public void send()<br />
        {<br />
            string to = "snaidis@gmail.com";<br />
            string from = "semionn.89@mail.ru";<br />
            MailMessage message = new MailMessage(from,to);<br />
            message.Subject = "Using the new SMTP client.";<br />
            message.Body = @"Using this new feature, you can send an e-mail message from an application very easily.";<br />
            SmtpPermission permission = new SmtpPermission(true);<br />
            SmtpClient client = new SmtpClient("smtp.mail.ru");<br />
            //client.UseDefaultCredentials = true;<br />
            client.Send(message);<br />
<br />
        }<br />
    }<br />

When I run it I have the following problem:

<br />
An unhandled exception of type 'System.Net.Mail.SmtpException' occurred in System.dll<br />
<br />
Additional information: Bad sequence of commands. The server response was: Administrative prohibition -- authorization required.  Users in your domain are not allowed to send email without authorization.  See http://www.mail.ru/pages/help/261.html for details.<br />

How do I authorize the account?

I don't really understand how to use that
I write
client.Credentials =
and then what?
for example if my user name is: abcd
and password: efg
?

The following worked for my ISP. mail.bellsouth.net and 25 are the SMTP server name and outgoing port number respectively.

private void btnTestEmail_Click(object sender, EventArgs e)
{

try
{
using (MailMessage message = new MailMessage(myEmail, myEmail, "subject1", "body1"))
{

SmtpClient mailClient = new SmtpClient("mail.bellsouth.net");

mailClient.UseDefaultCredentials = false;
CredentialCache myCache = new CredentialCache();

myCache.Add("mail.bellsouth.net", 25, "Basic", new NetworkCredential(myUserName, myPassword));

mailClient.Credentials = myCache;

mailClient.Send(message);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

Good Luck.

They've been all but gone from the net for years spammers would find and abuse them and the owner would have to implement authorization to get off blacklists.

OK, Please answer me to the question:

       string to = "snaidis@gmail.com";<br />
            string from = "semionn.89@mail.ru";<br />
            CredentialCache cache = new CredentialCache();<br />
            cache.Add(new Uri("http://mail.ru"), "basic", new NetworkCredential("MyAcc", "MyPass"));<br />
            MailMessage message = new MailMessage(from,to);<br />
            message.Subject = "Using the new SMTP client.";<br />
            message.Body = @"Using this new feature, you can send an e-mail message from an application very easily.";<br />
            SmtpPermission permission = new SmtpPermission(true);<br />
            SmtpClient client = new SmtpClient("smtp.mail.ru");<br />

Since UseDefaultCredentials defaults to true, perhaps you just need to explicitly set if false.

Have you replaced "MyAcc" "MyPass" with the user name and password for your account on the email server? Your user name is probably "semionn.89", I can't tell you what your password is. Big Grin | :-D

Can one XML file hold more than one C# object?

Can one XML file hold more than one C# object?

Say 2 or 3 ArrayLists?

I have more few questions regarding this, but this is basic question to make sense to others I have...

OK on simple example, I know how to do it with one object

say something like this is done:<br />
XmlSerializer ser = new XmlSerializer(typeof(ArrayList), new Type[] { typeof(SomeClass) });<br />
XmlTextWriter writ = new XmlTextWriter("List.xml", System.Text.Encoding.UTF8);<br />
ser.Serialize(writ, SomeList);<br />
writ.Close();

Can you show me example, loading for example two ArrayLists each hold diferent type of data...

I use F12 (right mouse click, GoToDefinition) to go to the Definition of a function.
What key can be used to go back to the source please?
Thanks

Well, if the definition is in a different source file, Ctrl+Tab will take you back. If it's in the same source file, set a bookmark first. There might be a keystroke to return you to your previous location, but I'm not aware of one.

CTRL/- goes to previous location ("navigate backward")
and CTRL/SHIFT/- is "navigate forward"

There are buttons for them on the "View" toolbar

Such buttons can show tooltip including shortcut
(enable thru Tools/Customize/Toolbars/Show ScreenTips on toolbars)

Very cool! I'd tried a few keywords in the keyboard customization to see if anything came up, but "navigate" wasn't one of them.

How can I get the % CPU usage

robert11019-Jan-07 5:07

I am needing to find out the current CPU usage to determine if I need to run a service or not. If the computer is currently busy then I would like to pause my win-services for x-amount of time and then run it again so users don’t feel the repercussions of my programming and vice versa.

In the Task Manager (at the bottom status bar) we can see the # of processes, CPU Usage etc. How I can get/calculate that? Are there any classes available?

Thanks in advance.

Have a look at System.Diagnostics.PerformanceCounter.

If you want to run a process that does not degrade the performance, you can start a thread with the Priority property set to BelowNormal.
