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.
I want to send an automatic E-mail based on the date. If the current date is greater than 5 days than the current date field in the table then i need to send an E-mail to the designated person. I am using VS.NET2003/VB.NET/ASP.NET/SQL Sever 2000.
View 2 RepliesI'm doing INVENTORY project...
front-end : vb.net
back-end : Access

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?

View 6 RepliesI 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 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.

I want to send an email that contains an attachment via vb.net and smtp. I used gmail as smtp server. This project works correctly when the size of attachment size is lower than 1Mb. When the size of the file is bigger than this size it makes an error. The message is this: "ContextSwitchDeadlock was detectedMessage: The CLR has been unable to transition from COM context 0x652fd8 to COM context 0x653148 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations."I extended the timeout period but this message is shown.
View 3 RepliesI have been searching for the answer to this for quite a while but none answer me exactly. Here is my problem, I want my user to be able to send an e-mail by clicking on a button "Send" and for this e-mailk to take the e-mail address from a text box and the message from a text box (Subject can be hard coded as it will always be the same) but I need to do it without using SMPT protocols as I don't want the user to have to input lots of information regarding their e-mail etc. Is there any way to do this.

I wrote a VB.NET application to send notifications by SMS using an SMTP gateway [URL]..The message includes line breaks and display well under most providers but not all.For some providers, the message will display in one line with line breaks showing as "0D0A" which just won't work for me.
Is therea solution to this problem?Using an SMS agregator is out of the question for my solution.
Yes, I did that. Turned out to be carrier specific. Yet another problem i am having is specific to the phone model (one specific user receive the messages well on his old razor, changed to a new motorola phone with the same carrier and now receives an empty message).
