VS 2008 Sending Mails - Acting Like A Server?
Jun 20, 2010
I have a software under contruction for a small firm. And it requires email functionality. That is, whenever the users in the main database reaches the payment date, an email will be send to that user as a reminder.Or, in certain period, the admin needs to send a notification mail to all the users in the main database.
So, how can I incorporate that facility in my main app ?My present idea is to create a separate app for send the mails. That is, when the admin compose the mail and selects a bunch of users (as recipients) from the database, all the message will be saved to another database (for mailing application) and will start the mailing app. This mailing app will check it's database for any pending emails to be sent, and if there exists any pending mails, it will start sending one by one. After sending each mail, it will remove that from the database.
What's your idea ? Does it sounds ok to you I don't want the user of my main app to know that there exist another program, running in background, sending emails.

I am trying to send e-mails with VB.net and I have a template for the code but I don't understand a few lines.[code...]
As far as I understand, mail.From is the sender's name, and mail.to.add is the person I am sending to. What does smtpServer.Credentials do?
I deduce that SmtpServer.Credentials is the only one that requires a password so that will be the account the e-mail will be sent from. But then what is the point of mail.From? What happens if I put different e-mails in credentials and mail.From.

The main problem is that to send an E-mail from G-mail, you need to use smtp.gmail.com as the host, and the port number 587.
Dim SMTPServer As New SmtpClient
SMTPServer.Host = "smtp.gmail.com"
SMTPServer.Port = 587
SMTPServer.EnableSsl = True
However, for Hotmail, I would need a different Host and Port, smtp.live.com. Other E-mail clients would therefore require more different hosts. Is there a way, to address all of them without listing all possible E-mail host names and ports?
If not, what alternative is there to supporting all the E-mail hosts without throwing an error?

I am using VB.net to send my mails through outlook. Where i am giving the resource path for the pictures inserted in to it.
But Email shows the inline pictures as attachments. what could be the reason?
The important thing is that this is not happening all the time. if we send 5 to 10 times we get the expected result for 2 or 3 times.
i explored some of the forums , got answers like 'changing the settings, security settings of the office outlook. that too is not succeeded.
I am giving you the code I am using in my project.
The code is given below

I have a mailbox that gets alerts from different servers from time to time. Each time, we get this alert, I want it to perform a custom action based on the contents of the email.And I would like to keep it as a service in (C# or VB.net) which can be run from anywhere. Is there an API for reading this?

I am developing a vb.net desktop application that reads mails from the mailserver using pop and imap. The application is almost fnished .The problem is the some time when a command is send to retrieve a mail using GetMessage() functions the applications is going to a halt. So I tried to run the the code in debug mode and ran line by line.
What I noticed is in the while loop in GetMessage() function is
While Not tmpString.StartsWith(sPrefix)
tmpString = reader.ReadLine
msg = msg & tmpString & vbCrLf
End While
The reader reads line by line at certain point of time it got hangs. Some times it ill catch an exception and give an error. I am pasting the exception below:
"Received an unexpected EOF or 0 bytes from the transport stream".
But some times the applications will hang and go for a halt. This applications has to run 24/7. So if it hangs in the night or it will be problem. What I want is if the reader is not able to read from the stream after certain time period. The control has to be removed from the reader and the function has to return a message. I am new to this the network level applications and I am running shot of time.
Public Sub connect()
Dim objTCP As New TcpClient
Dim sslstream As Net.Security.SslStream
Dim reader As StreamReader = Nothing

The error is on this line:

Heres the Client:

If TextBox1.Text = "" Then

I'm trying to write my own SMTP server at the moment so that people can use it in their applications to send and receive emails.I am having a few problems at the moment with the TcpListener side of things though. Basically I do not want to start the TcpListener in the constructor of my class because people could be using this SMTP Server class just to send emails and might not care about receiving them. In fact the majority of people that use it will probably use it for that reason, to send and not to receive.
So I am now considering breaking this into 2 totally separate projects that have no dependencies on each other, but could easily be used in the same application if required. The reason I designed this with both 'features' in the same project in the first place was because that is how an SMTP server works - it can receive incoming SMTP requests and it can send SMTP server requests to other servers (and in some cases, receiving an SMTP request would cause it to send an SMTP command to another server)

Am devloping an application with multiple forms, which reside on top of a main form. i.e the main application window. The 'child' forms do not need to be linked in any way as they do not pass information to the parent form, as all the parent form does is act as main window.Now I would like to know what is the correct way for the 'main window' form acting as a container for the other forms? So that all the smaller secondary forms stay focused on top of the main application form, that when the main window is minimized, so these forms should do also etc..
I have read other posts and they mention, leaving all the forms standard i.e. IsMdiContainer = False and then using form.showDialog() to call the secondary forms. This did not work for me as what happens is that as soon as I give focus to the main app form, the secondary form disappears underneath.I tired making the main app form IsMdiContainer = True and when it loads calling:
frmMemberForm.MdiParent = Me
Now this works, because I can click off the form and minimize the app etc and the frmMemberForm doesn't disappear. However if i close the MemberForm and reopen it, it looses this property and once again when it looses focus, it will disappear.

how to send a log using vb.net console app to a external server? I have the application sitting in a store oulet, then I need this application to send over a log file.
I have a couple of ideas.. one is using a tcp listener and sender, then the listener logs it over in the server.
Another is using a ftp send.
but I would prefer it to be coded in the program itself.

I am working on an application that is going to read a weight from a scale. The people who sold us the scale said that I can send a string to the scale over FTP and the response I will get is the weight. I haven't done much with ftp and have been searching for weeks. Can anyone point me in the right direction? The steps are... Create a TCP/IP connection to the ip address, port 1701 If the connection is succesful then I'll get 53 Ready for user as the response I can then send the username/password to the machine (sent as a string...) Read the response, which should be 12 Access OK I then need to transmit 'r wt0101' to read the weight. The response will have the weight. They've said this is done through FTP but maybe that's not the case? I don't understand why it would be FTP but that's what the technical documents say. Is there a class I can use that sends string commands over a tcp/ip connection?

I'm trying to send a simple email via vb.net. This is the first time i've tried this and am getting the same message every time. I've looked everywhere with no answer... The host that i use is bluehost, and i know the port name and the client name and username and password are correct. So i'm not sure what i'm doing wrong, perhaps it's thinking i should be sending from my localhost, or my ip address? Either way, below is the error i'm getting, and the code. The # just represent the numbers in the error and so on and so forth.
Mailbox unavailable. The server response was: cpe - ##-###-###-###... (my-pc)[my ip address] is currently at...
Try
Dim Mail As New MailMessage
Mail.Subject = "The Email Subject"
