Do you have an smtp server running at 192.168.1.15:808 ?
probably not.
You should use the smtp relay host that your isp has given you. (use the fqdn, not the ip-address) If you don't have mail at an isp, this won't work. (live.com does not provide smtp relay services). Also, your isp may limit the from: address, and may require authentication when sending mail.

hi their,u have told me to use fqdn instead of smtp
class n also u have mentioned tat "live.com does not provide smtp relay services" then which mail portal does support to send mails without any limitation or minimum limitation...
how do i find fqdn....?
could u give the exact coding to accomplish my task?

fqdn means fully qualified domain name. Try Google if you don't understand a word.
What you're looking for is an 'open smtp relay' (look it up before replying). Technically not illegal, but if you find one, your mail will probably be blocked by the recipient's ISP. Are you trying to get into the spam business?
You will have to set up your own smtp server if you want to send mail without limitations, but if you start spamming,
expect
1) Your Internet account to be closed down by your ISP
2) If you're really good at it, a visit from the Feds. (CAN-SPAM act of 2003).
If your intentions are pure, have a look at this list: http://www.iopus.com/guides/bestpopsmtp.htm[^]

You will probably have to turn on SSL (secure sockets layer) to get access to server. Turn on the EnableSsl property of your SmtpClient object. You may also have to select another port to send on. Talk to whoever is administering the smtp server, or read any documentation for this smtp server. If you already can send mail through this server, from another program (outlook, or windows mail, or whatever), lookup the connection parameters in that program.
Here is full example of mail client that uses SSL: http://www.codeproject.com/Articles/66257/Sending-Mails-in-NET-Framework.aspx[^]

Hi
I am creating custom collection object that inherits arraylist, ienumerable, etc. Because I can't go for Generic list since, that doesn't have event support (insert, add, remove, etc...)
I need some events to be raised on item add/remove/insert on list
public class CustomList<T> : ArrayList, IBindingList , IArrayList<T>
this supports linq, if I use object type in the linq query
var aa = (from User a
in users
where a.IsDirty == false
select a).ToList();
The problem, i could not use extension methods (.Where, etc..)
public class CustomList<T> : ArrayList, IBindingList , IArrayList<T>,IEnumerable<T>, IEnumerable
public new IEnumerator<T> GetEnumerator()
{
return this.GetEnumerator();
}
But this doesn't filter the objects in the list. for example users.Where(a=>a.isDirty == true);
Also if I inherit Ienumerable I get 'System.StackOverflowException' exception.
Please help

list supports add, removve, insert . But I think it doesnt support events
public interface IArrayList<T>
{
int Add(T value);
void Clear();
//bool Contains(T value);
//int IndexOf(T value);
void Insert(int index, T value);
void Remove(T value);
void RemoveAt(int index);

I think you're confusing events with methods. Read the documentation again.

my issue is not events/methods, how to incorporate the linq, extention support in to custom list.
public class CustomList<T> : ArrayList, IBindingList , IArrayList<T>,IEnumerable<T>, IEnumerable
{
public new IEnumerator<T> GetEnumerator()
{
return this.GetEnumerator();
}
}
1.
var aa = (from User a
in users
where a.IsDirty == false
select a).ToList();
this works, but public new IEnumerator<T> GetEnumerator() throws stackoverflow exception.
2. users.Where(a=> a.IsDirty == false);
this always returns empty/null

The problem is you are trying to create something that already exists

linq, extension methods work after casting the objects.
public class CustomList<T> : ArrayList, IBindingList , IArrayList<T>
I removed IEnumerable from the customList
users.Cast<User>().Where(a=> a.IsNew).ToList()
var aa = (from User a
in users
where a.IsDirty == false
select a).ToList();

Yes, Collection is better choice.
protected override void RemoveItem(int index) {}
Collection doesn't have RemoveItem(object item) method to override....
so couldn't raise remove event, on removing by object.....
any fix for this?
Thanks in Advance

If all you want to do is raise an event, you should probably just use ObservableCollection, which does raise events on add/insert, remove, and setting items. The Remove(T item) will call the protected overridable RemoveItem(int index) after figuring out the proper index, that's why only one is overridable.

It's not something that you build, but a way of building something. Some of those idea's are described in this[^] book
