I agree with the idea that you should focus on learning the basics of the IDE first ... you don't tell us here whether your target goal is to work in WinForms, WPF, SilverLight, ASP.NET, etc. ... and I do suggest you specify that, since book recommendations might vary greatly depending on which of those platforms you are targeting.
For basic books on C#, I suggest you get Jesse Liberty's latest:[^].

I managed to send emails but if I change client.Host = "smtp.gmail.com" to client.Host = "smtp.hotmail.com" or client.Host = "smtp.yahoo.com"; it does that works only with gmail
namespace mailing
{
public partial class SendMail : Form
{
public SmtpClient client = new SmtpClient();
public MailMessage msg = new MailMessage();
public NetworkCredential smtpCreds = new NetworkCredential("aa@gmail.com", "aaa");
public SendMail()
{
InitializeComponent();
}
public void SendMails(string sendFrom, string sendTo, string subject, string body)
{
try
{
client.Host = "smtp.gmail.com";
client.Port = 587;
client.UseDefaultCredentials = false;
client.Credentials = smtpCreds;
client.EnableSsl = true;
MailAddress to = new MailAddress(sendTo);
MailAddress from = new MailAddress(sendFrom);
msg.Subject = txtSubject.Text;
msg.Body ="<html><body>"+txtMail.Text+"</body></html>";
msg.IsBodyHtml = true;
msg.From = new System.Net.Mail.MailAddress(txtFrom.Text);
msg.To.Add(txtTo.Text);
// Attachment piece_joint = new Attachment(@"txtpiece.Text", MediaTypeNames.Application.Pdf);
AlternateView alternate = AlternateView.CreateAlternateViewFromString(msg.Body,null,MediaTypeNames.Text.Html);
LinkedResource img = new LinkedResource(@txtpiece.Text, MediaTypeNames.Image.Jpeg);
img.ContentId = "idimg";
alternate.LinkedResources.Add(img);
msg.AlternateViews.Add(alternate);
msg.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess | DeliveryNotificationOptions.OnFailure;
client.SendCompleted += new SendCompletedEventHandler(smtp_sendcompleted);
client.SendAsync(msg,null);
}
catch (Exception ex)
{
MessageBox.Show("Failed to send this mail" +ex.Message);
}
}
static void smtp_sendcompleted(object sender,AsyncCompletedEventArgs e)
{
if (e.Error != null)
{
MessageBox.Show(""+e.Error);
}
else if (e.Cancelled)
{
MessageBox.Show("envoi annulé");
}
else
{
SpeechSynthesizer synthesizer = new SpeechSynthesizer();
PromptBuilder promptBuilder = new PromptBuilder();
promptBuilder.AppendText("the mail has been sent");
synthesizer.Speak(promptBuilder);
}
}
private void btnEnvoyer_Click(object sender, EventArgs e)
{
SendMails(txtFrom.Text, txtTo.Text, txtSubject.Text, txtMail.Text);
}

You have to make sure the port your using matches the specification of those other hosts. Google uses 587 for secured communication to the SMTP server. Hotmail and Yahoo will probably not use the same port numbers. Check with them.

Port 587 is a standard for SMTP servers (similar to port 25), usually referred to as the 'submission' port. It's set aside for authenticated users to submit messages to the e-mail service. It typically needs encryption, but I don't believe that's a requirement of the standard.
https://www.ietf.org/rfc/rfc2476.txt[^]
|
|

|

It may be standard, but that doesn't mean people have to use it.
Yahoo uses different ports, depending on which service level your have. I think, last I checked anyway, one is using port 995 and the other 465???
|
|
|
|

True, standards can be ignored but it's worth pointing out that the ports listed weren't just arbitrarily chosen by the service provider.
995 is used for encrypting the POP3 protocol (POP3S, another standard  ).
Port 465 is an old remnant from Exchange's method of encryption. It's become common due to Outlook/Microsoft's support of Exchange over the Submission port standard in their mail clients. These days, both protocols are supported in Outlook. One other note about 465 is that it will break using System.Net.Mail.SmtpClient due to how the encryption was implemented. See the remarks section at http://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient.enablessl.aspx[^] for the details.
|
|
|
|
|
Yeah, but the entire point was he needs to check with each provider to make sure the port settings are correct and hes using the correct connection options.

Most SMTP servers require you to be an authorised user (i.e. if I use Clara.net as my ISP, I can use the smtp.clara.net relay, but if you don't, you can't). Gmail allows you to use your Gmail account details to log into SMTP; I'm not sure if Hotmail and Yahoo do something similar but if so, at the minimum, you will have to change the credentials you're trying to use.
|
|
|
|
|
yes I have already tested it does not work with yahoo and hotmail: Exception: authetification required
|
|
|
|
|
So are you using the correct username and password with Yahoo and Hotmail?? I'm gussing your GMail account and password are not going to work with those providers.
|
|
|
|
|
I'm sorry I misunderstood, and I will explain when I send a mail and the sender is a user with a gmail account it works, I sent mail to Yahho and hotmail without any problems but if I Chenge sender then there is the problem
|
|
|
|
|
Yeah, and I'll say it again. The error message says that the username and password you used to login to the SMTP server were not good credentials. Either the username was spelled wrong or that account doesn't exist on that server or the password you specified for that username wasn't correct.

Hi,
You can refer email sending code snippet
in below link Send email using htomail
Smtp used for HOTMail is
SMTP: smtp.live.com

If you have a search on Google you may find some free to use public smtp hosts. I did use a one a few years abck for a project - don't recall the name but worth a try.

Change this line of code:
public NetworkCredential smtpCreds = new NetworkCredential("aa@gmail.com", "aaa");
Note that the credentials are pointing to gmail. You get that when you stare at a passage of code long enough.

And of course John.Doe@hotmail.com is not allowed to send an email with the sender of the email set to John.Doe@gmail.com. That's not a requirement of the smtp protocol, but a requirement of any sensible provider, oh spammer!

Hi,
My idea is converting an RTF document to HTML because the rich text control offers the RTF output result.
1)You can use this article to create an advanced rich text box: RicherTextBox
2)To convert the RTF result, you can use the
"SautinSoft.RtfToHtml" . For the trial version you can convert over 30000 words 
<pre> private string GetHtmlText(string strRtfText)
{
if (string.IsNullOrEmpty(strRtfText)) return "";
string result = "";
#region Version SautinSoft
SautinSoft.RtfToHtml r = new SautinSoft.RtfToHtml();
r.OutputFormat = SautinSoft.RtfToHtml.eOutputFormat.HTML_5;
r.Encoding = SautinSoft.RtfToHtml.eEncoding.UTF_8;
r.ImageStyle.ImageFolder = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "\\TempFiles";
r.ImageStyle.ImageSubFolder = "webs";
r.ImageStyle.ImageFileName = "picture";
r.ImageStyle.IncludeImageInHtml = true;
result = r.ConvertString(strRtfText);
#endregion
return result;
}

fyi: SautinSoft RTF=>HTML full version which can handle > 30k words is a US $239 component, on SautinSoft's web-site.
Has the OP searched here on CP for RTF to HTML conversion ? On StackOverFlow, on Google, for other free controls ?
