Excellent!!

It will be very handy to learn also how to use the collections.

Thanks Chris.

Very nicely done.

It's good video for me. Thanks

Hi

it is very helpfull but i don't know how to make it on Vista.

do you know some place where "yellowhead" like me can teach how to make it on Vista?

sorry i don't write why?

because Vista haven't got some mailClient

Thanks very informative

Why are all the learning videos in VB ?

Thanks for the Video..

Please, why they have to be in VB all the time?

Thank you

Very nice.. wonder why no use of "Imports System.Net.Mail"

Nicely done. It's very helpful. Thanks.

Thanks for video.It's very helpful.

Thanks so much for this video.  Can you also show us how to handle the attachment size check before attaching it to the e-mail.  I found the program doesn't even throw an exception when user attachs large size e-mail.  It just dies...

thanks!

This example works fine when I use my local Exchange Server but when I use the SMTP server on a Windows Server 2008 box on the same domain (this is my own remote web server over which I have total conrol), I get "Unable to read data from the transport connection: net_io_connectionclosed".

I've tried no credentials, default credentials and specific credentials.  How do I make this work?

how do I redirect the user when the email has been sent to  a thank you page, and when the email has not been send to an error page?

VB code n C# code is interchanged

k but even i have some error in mail

I have this Server Error Application

No connection could be made because the target machine actively refused it ...

It is something about my smtp server??  Someone knows a smtp server that I can use to test it?

Can u exlain me how to create inbox in ur next video ?

Thanks for great video

Thanks for this video .. it is so easy on the eyes. You have a good teaching style.

Both code downloads contain the VB lanugage.  Do you have a C# version of the code?

Can we have the C# code ?

Hi Chris,

I have successfully set up my createuserwizard and the finish step that sends the email works correctly and the email is sent.  However when i try and implement the password recovery wizard that sends an email to the user the email is blocked by the smtp server with this message:

Mailbox unavailable. The server response was: Authentication is required for relay

how can one of these be denied and the other not ?

don't they both use the smtp settings in the smtp section of the web.config file ?

Here is that section of the web.config file:

 <!-- Add the email settings to the <system.net> element -->

 <system.net>

   <mailSettings>

     <smtp from="webMaster@aaaSite.com">

       <network

            host="mail.aaaSite.com"

            userName="usernameValue"

            port="25"

            password="passwordValue"  />

     </smtp>

   </mailSettings >

 </system.net>

Thanks

Greg

source  code  links are swapped :) vb->cs

Thanks for video.It's very helpful.

Links are not crossed.  They are both in VB

The VB & the C# links both download the VB version of this application.

No connection could be made because the target machine actively refused it XXX.0.0.1:25

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Line 21:

Line 22:     End Sub

Your example didn't work for me do you know were I went wrong???

i am not understanding about the host in smtoClient.Can i use my system IP address as host?Can u tell me about host?

Thanks for video  

Actually both of the code examples are in VB... neither has C#.

Hi Chris,

loved the demo, even the video was up to your normal quality. however the code for C# is missing hope you can fix this problem soon.

Thanks

Why are all the learning videos in VB ?

Hi Chris!

Very useful video, thanks!

Hi there

It would be really useful if we could have the c# code too.

Cheers!

there is no c# code here. link is broken

Here is the c# code for the code behind file

Default.aspx.cs

---------------

using System.Net.Mail;

protected void btnSend_Click(object sender, EventArgs e) {

//Create instance of main mail message class.

MailMessage mailMessage = new MailMessage();

//Configure mail mesage

//Set the From address with user input

// mailMessage.From = New System.Net.Mail.MailAddress(txtFromAddress.Text.Trim())

//Get From address in web.config

mailMessage.From = new MailAddress(ConfigurationManager.AppSettings["fromEmailAddress"]);

//Another option is the "from" attirbute in the <smtp> element in the web.config.

//Set additinal addresses

mailMessage.To.Add(new MailAddress(txtToAddress.Text.Trim()));

//mailMessage.CC

//mailMessage.Bcc

//mailMessage.ReplyTo

//Set additional options

mailMessage.Priority = MailPriority.High;

//Text/HTML

mailMessage.IsBodyHtml = false;

//Set the subjet and body text

mailMessage.Subject = txtSubject.Text.Trim();

mailMessage.Body = txtBody.Text.Trim();

//Add one to many attachments

//mailMessage.Attachments.Add(New System.Net.Mail.Attachment("c:\temp.txt")

//Create an instance of the SmtpClient class for sending the email

SmtpClient smtpClient = new SmtpClient();

//Use a Try/Catch block to trap sending errors

//Especially useful when looping through multiple sends

try {

smtpClient.Send(mailMessage);

}

catch(SmtpException smtpExc) {

//Log error information on which email failed.

}

catch(Exception Exception) {

//Log general errors

}

}

please i don no how to know my host can some explain 2 me the steps and how to set the port and password

How many emails i can send per day? Is there a limit ?

Hi Chris,

Great video thanks. I am having one issue with the attachment piece. It seems I can not get the attachment to work when I use a folder on my C drive typing the string in as you did in your video. Error comes up with file not found even though I know it's there. I did discover that if I take the path out and just attach a file name, it looked in the 'C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE' folder. Once I put my file there, everything worked perfectly. I am sure there is some way to change this to the path I need but I can't find where to do this. Any help would be appreciated.

Thanks!

The C# code works perfectly from dev environment. When I load to the production, web server I get an error: "Failure Sending Email".

Any thoughts?

Thanks!

good video

but when I used c# code , no errors no exceptions but no mail is recieved !!!

what the problem ?
