Hi there,
Have a look into CAPTCHA's.
If you don't like this, another option to add a hidden textbox. Spam bots will generally fill in every box on the page (hidden or not) and then submit the form.
All you have to do is check that the hidden box is empty - if not, it is a non-human user.
Cheers,
Mark Brock

I might be mistaken, but I think there's something in the SMTP protocol which allows this. If you're feeling particularly masochistic you could implement this. I think it works in a similar way to POP - that is, text based requests and responses.

I am using this code to send an email using MailMessage:
msg.Body = txtMessage.Text;
but it's all coming as one paragraph without the line breaks though I have enter key between every paragraph?
how can I fix this in Windows Application?

You should use the IsBodyHtml property like this:
mail.Body = "first line<br/>next line";
mail.IsBodyHtml = True

it is set to true.. but it's still not considering the ENTER key and it's all coming as one paragraph!
msg.Subject = subject;
msg.Body = message;
msg.IsBodyHtml = true;

And it will not. ENTER key is /r/n which is not html. The mail message expects the body message to be valid html else it gets confused.
Can you try this:
msg.Subject = subject;
message = message.Replace(@"\r\n", "<br/>");
msg.Body = message;
msg.IsBodyHtml = true;

I tried but it's still the same.. here is the code:
msg.Subject = subject;
message = message.Replace(@"\r\n", "");
msg.Body = message;
msg.IsBodyHtml = true;

Ah!!! the text editor screwed the code 
msg.Subject = subject;
message = message.Replace(@"\r\n", "<br/>");
msg.Body = message;
msg.IsBodyHtml = true;
Can you try the above?

i want to know what's the best way to check for new version of my C# windows application while the application starts?

You can use Click Once[^] deployment.
only two letters away from being an asset

I am planning on writing a webservice that let's my app do this, and download updates. Clickonce has it's issues, not least that the programs don't end up in program files.

This gets asked here CONSTANTLY. You need to find a local service that allows you to do this, and subscribe to it.

Hello,
i've implemented an application that read from a local db and write on a server db using a transaction scope. When I try to commit the transaction i receive an exception error
:
System.Transactions.TransactionManagerCommunicationException: Impossible to comunicate with transaction manager...System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL ...
in System.Transactions.Oletx.IDtcProxyShimFactory.ReceiveTransaction(UInt32 propgationTokenSize, Byte[] propgationToken, IntPtr managedIdentifier, Guid& transactionIdentifier, OletxTransactionIsolationLevel& isolationLevel, ITransactionShim& transactionShim)
in System.Transactions.TransactionInterop.GetOletxTransactionFromTransmitterPropigationToken(Byte[] propagationToken)
I've enabled MSDTC on client and server but something is wrong.
Please help if you know the solution.
Thanks in advance

I've resolved. The client open a comunication with the server. Then close the comunication and wait. The server open a new comunication(with a dinamic port number) with the client and try to send information. So if on the client there's a firewall that block msdtc.exe process the comunication failed.
So to resolve create a specific rule for the msdtc.exe process on client.
Bye.
