I have done a lot of searching in this forum which regards to my topic and it turns out that i'm kinda confused.. considering that i don't have any experience when comes to ports and stuffs. So i made my own thread for me to be on the right track..

I am trying to Send an Email with an attachment (using Gmail) but I keep getting errors like "Operation Timed out" or Failure Sending Email". It was working earlier today but I found out that i needed to add Using statement because the email was having a file open that had to be deleted after it was sent but afterwards it doesn't work.
Here's what I have (Portion of it):
Private Sub SendMailOneAttachment(ByVal un As String, ByVal pass As String, Optional ByVal smtp As String = "smtp.gmail.com")
Using oAttach As Net.Mail.Attachment = New Net.Mail.Attachment((Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) & "\" & My.Computer.Name & "_" & fName & " .zip"))
Dim client As SmtpClient = New SmtpClient(smtp)
[Code] .....
The ports are correct I believe, no firewall up on my PC...

View 3 RepliesI have this code below and everytime I run it I get this error.
Private Sub SendEmail(ByVal sender As Object, ByVal e As EventArgs) Handles Button2.Click
Email.To.Add(Settings.txtTo.Text)
Email.From = New MailAddress(Settings.txtFrom.Text)
Email.Body = "Email Body"
[code]....
The error I get is: The parameter 'addresses' cannot be an empty string. Parameter name: addresses And it's pointing to the Email.To.Add() section.
I've been able to create and send an e-mail using System.net.mail. But it appears that the message isn't being sent until the application closes. This causes two major problems for me.1) When the user tries to send a second message, I get the following error: a generic error occurred in GDI+. I believe this is caused because I'm creating and sending a screen shot. If I take out the screen shot the error goes away. The screen shot is nice but not necessary. I can work around it, if I have to.
2) I am using the e-mail to provide notification that a process has been completed. The sender may continue to do other work while in the application -- including sending an e-mail to another recipient.
What do I need to do to get the e-mail to be sent before the application is closed?
I've got a client/server communicating nicely using TCP to send text strings and to parse and act upon the messages at either end, but now I want to be able to send small files. I thought it would be as simple as reading the contents of the file into a buffer and sending that buffer as if it was a message but obviously not. When I retrieve the message at the client end I get "System.Byte[]" so its given me the variable type and not the actual contents of the array I thought I'd passed in!
My Sending code is this :
Public Sub SendFile(ByVal Filename As String)
Dim sw As IO.StreamWriter
Dim fs As IO.FileStream
[code]....
(NB I did search for this within the forum and found some examples but they just didn't fit very well with the framework of what I'm doing, such as creating a 2nd tcp channel to handle file transfers?

Have this Uni question; which after 20 minutes of frustration I'm sending it to the brain trust (you might be interested).Write a program that, when a button is pressed, checks the contents of a textbox. If the textbox does not contain a number, the program informs the user of this and does nothing more. Once a number has been entered, the program will do something trivial such as displaying double the number in a message box.Notice that this can be done without explicit looping,even though the user might repeatedly enter non-numbers. Because it is an event-driven program, each iteration is started when the user clicks the button. The looping is driven by the user, not by a looping statement.
View 5 RepliesMy latest project requires both sending and receiving emails. Now i know how to send emails using a gmail account, but what im having incredible difficulty with, is accepting emails. What i want, is to have a program that both has the ability to send emails, and capture emails being sent to the logged in user, and place them in an inbox list. I was wondering if anyone knew how to receive emails with a program, even temporarily, so that when an email is sent to the user, my program knows about it, and can take the body from the email, and place it in say a textbox.

Dim s As New Random
Dim l As New Random
