If there was a way to view passwords on any system, then that system's security is compromised. As a teacher of IT you really should understand that.

And I should take a class to learn that?

If you are talking about CodeProject articles, then there is a forum at the end of each article which allows you to ask the author. If you are talking about your own implementation then show what you have done, explain what is not working, and people will try to help you.
Use the best guess

Make sure your application pool is set to the correct framework in your IIS Manager e.g.
if your website is build with framework 4, make sure you application pool is set to .Net Framework Version v4.0.
And if your website is build with framework 3.5, make sure you application pool is set to .Net Framework Version v2.0.

I made the modification but it still doesn't working still
|
|
|
|

If you use deploy, then you have to be aware that it does not always deploy everything.
You may need to look into a library that exist on your local dev but not on your deployed iis,
Check the dlls, and controls etc..
Make sure that they are all either in your app bin dir or registered on your deployment box.

Try using a MemoryStream[^] to store the Excel file, and pass that stream to the Attachment constructor[^].
var ms = new MemoryStream();
using (var sw = new StreamWriter(ms))
{
RenderExcelAttachment(sw);
}
var attachment = new Attachment(ms, "data.xlsx", "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
message.Attachments.Add(attachment);

Hey all,
I want to add a Return-Path to my message so that Bounces can be send to a specific email address.
I tried adding
mm.Header.Add("Return-Path",email) to my MailMessage, but no luck. I've done some research but found nothing useful. Some guys said that it is impossible with system.net.mail.
Any work around or ideas will be appreciated.
Thanks

I believe the Return-Path header is set based on the Sender property[^].

What version of asp.net are you using?
The code for 2.0/3.5 is different that 4.0

You use netmail, the mailclient and mail exception to track errors
Dim NetMail As New MailMessage
Dim MailClient As New SmtpClient
Dim smtp_credentials As Net.NetworkCredential = Nothing
Dim mailException As New SmtpException
Then you create your target, subject, encoding and so forth.
NetMail.From = _
New MailAddress(smtpC.Options_WebsiteName & " <" & smtpC.Options_ReplyTo & ">")
NetMail.ReplyToList.Add(New MailAddress(smtpC.Options_WebsiteName & " < " & smtpC.Options_ReplyTo & " > "))
NetMail.To.Add(New MailAddress(m_CustomerName & "<" & m_EmailAddress & ">"))
NetMail.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure
NetMail.IsBodyHtml = True
NetMail.BodyEncoding = System.Text.Encoding.UTF8
NetMail.Priority = MailPriority.Normal
NetMail.Subject = m_RM.GetString("Confirmation of Payment for Order Number")
If your message is HTML, use the NetMail.Body. YOur Body can be any mix and match of properly formatted HTML code, packaged as a string or use can use a string Builder.tostring
NetMail.Body = html_Template.ToString
This part is tricky, I've been playing around with this for a couple of months now, and I think I have it now. I've had to adjust sending credentials to exchange servers in a windows domain, and plain smtp servers outside the domain.
select case smtpC.Connector_AuthMethod.ToUpper
Case "WINDOWS"
If (Convert.ToBoolean(smtpC.Connector_DefaultCredentials) = True) Then
MailClient.UseDefaultCredentials = True
Else
MailClient.UseDefaultCredentials = False
smtp_credentials = New Net.NetworkCredential
smtp_credentials.Domain = smtpC.Credentials_DomainName
smtp_credentials.UserName = smtpC.Credentials_LoginID
smtp_credentials.Password = smtpC.Credentials_Password
MailClient.Credentials = smtp_credentials
End If
Case "SMTP"
MailClient.UseDefaultCredentials = False
smtp_credentials = New Net.NetworkCredential
smtp_credentials.Domain = smtpC.Credentials_DomainName
smtp_credentials.UserName = smtpC.Credentials_LoginID
smtp_credentials.Password = smtpC.Credentials_Password
MailClient.Credentials = smtp_credentials
Now I set the port, host and delivery method and send the message
MailClient.DeliveryMethod = SmtpDeliveryMethod.Network
MailClient.Host = smtpC.Connector_ServerAddress
MailClient.Port = smtpC.Connector_SMTP_PortNum
MailClient.Send(NetMail)
And then dispose of the netmail object
If Not (NetMail Is Nothing) Then
NetMail.Dispose()
NetMail = Nothing
End If

Hi,
I have windows application developed in VB.NET
Visual Studio 2008
.NET Framework 3.5
SQL Server 2005 Express Edition
The application has a setup project, on clicking the setup.exe the setup runs and the application gets installed on the user’s machine
The setup checks for the existence on SQL Server 2005 Express Edition in user’s machine, if it is not present then it installs the SQL Server 2005 Express edition.
The application works fine on Windows XP and Vista, but it is not working fine on Windows 7, after the set is run on windows 7 the “Unhandled exception” occurs.
Exception details are

This error is only faced in Windows 7,
The application is working fine in Windows XP and Vista
|
|

Just lok at the text of the error message: "Cannot create a file when that file already exists".
And where does that happen?
Somewhere called from the Load event handler of frmLogin: DataEntryApplication.frmLogin.frmLogin_Load(Object sender, EventArgs e)
There you write some log files, and try to move a file: System.IO.FileInfo.MoveTo(String destFileName)
And when you try to do so, that file (whose name is stored in destFileName) does already exist.
Two options:
check for the file before you move it, and
- use a different name.
- delete the existing file
