I am working on a project in which admin wants to send updates of website via email to all registered users on web site.How to do this.?
[Code]...
This is the backend code i am using for sending 1 email.How can i use this to send emails in bulk?
Basically this is my problem, showing the results of a string. I am making a program for a customer and he wants to be able to extract a string or set of emails from a large group of text. In this case he wants to be able to copy a webpage and extract all the emails out of the webpage. The problem i am having is showing the results of the List(of string) Function. So far, I can copy the page, paste the content to a textbox and then i have a function that is supposed to filter out the emails and paste or Show them in a list box.
I dont know why but no matter what I do I always get this error:
Error1Value of type 'System.Collections.Generic.List(Of String)' cannot be converted to 'String'.
This happens when I try to output the return results to a textbox or list box.
Here is the code for the whole program:
Entire Program Code:
Imports System.Text.RegularExpressions
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code] .....
I have tried almost everything I could do, I am relatively new to string functions so that is my main problem.
class code:-
Imports Microsoft.VisualBasic
Imports System.Net.Mail
Public Class SendEmail

code inside the ctrl "button sub"
Dim objemail As New SendEmail
objemail.Mailto = txtEmail.Text
objemail.email()
LabelEmail.Text = "The email has been sent"
The specified string is not in the form required for an e-mail address, and i have tried to intilize vaild email in "mailto" field and ive removed everything in proprieties and fields?
Now there's a user "A" who has 100 followers...now what i want to do is whenever user "A" submits an article in the website all his followers should get an email with the article link...that is okay i can do it.
Problem: Now, there's a submit button on the page which stores the article in the DB and sends email to the followers...as there are many followers it takes a lot of time sending the emails...so the page keeps showing loading msg till all the emails are sent..how can i send all the emails asynchronously ??
i mean after the article has been submitted ...the emails should go automatically to the followers without putting the email sending function in the click event of the button....hope am not confusing you folks.
can i do something like store the article in the DB , redirect to the article page , start sending emails in a batch of 10 per 10 mins automatically...this process should start as soon as an article has been submitted by an user.
What are the different ways to send the emails using vb.net?
View 4 RepliesI have been trying to make my own app for sending emails. But I have been trying to make it where I don't have to sign into my hotmail account, it just does it automatically. Then all I need to do is fill out the recipients, subject, and body for the message and hit send but I am having issues. I can't for the life of me get it to work. After a week of messing around with it and scouring the internet for help, I have gotten to where the only error I get is, failure to send message.
Imports System.Net.Mail
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[code]....
I have been working on this because I can't use Outlook with hotmail and I figured it would be interesting to try, but it turns out to be a lot harder than I expected.
On my Contacts page I have a form with Name,Email,Subject,Message textboxes.when I click the Send button I receive this error message "The SMTP server requires a secure connection or the client was not authenticated. The server response was: authentication required"this is the code I have behind the Send button
Protected Sub btnsend_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnsend.Click

View 5 RepliesI'm currently using SmtpClient to send emails to users that register or sign up for an event.When they click register it saves the info and calls the send email function, but it takes slightly less than a second to send an email which is too long.Is there a way to save the users info and after the page is loaded it calls the send email function from vb in the background.

PROBLEM: I want to send the emails asynchronously using threading or a windows service. I am not sure about windows service as I am using a shared hosting. But my real concern is that I want to send out the emails only when traffic is low in my site. How do I go about this? Ho do I check if traffic is low or not?
My 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.

I am using VB5 on a Windows XP SP3 computer.I have an application that send emails to customers that have birthdays today and that bought a product from me today. If I run the application several times with the same search criteria with the same customers and the same date and time, I "may" or "may not" get the save Emails sent out.I am using a MAPI Signon prior to the birthday select and MAPI Signoff after the birthday select; another MAPI Signon prior to the sales today select and MAPI Signoff after the sales today select.I count the emails that are supposed to be produced in each select above and the counts are correct. It's the emails that may not agree with the counts.What could cause this?
View 1 RepliesI have a VB.net web service that returns JSON that works fine. Once the response gets to a certain size though, the client browser says that the server has closed the connection and sent no data. This is true using IE, Chrome, or Firefox. The magic size seems to be about 16383 records, or about 1.13MB of data. I know this is slightly large for a web service.

So I would like an email program that within the code already has the from email adress, gmail. I would like it to let you enter the number of emails to send to the address that you enter, not the one in the code. Also I would like it to be able to enter the message.
View 2 RepliesI work with a large shared mailbox within which several individuals each have a folder of their own. I am trying to develop a tool which will monitor how many emails each individual has in their own folder including a breakdown of what categories have been applied to each email (IE In my Subfolder there are 20 Emails - 10 Blue, 5 Red).I have already coded a prototype but so far I have only been able to get a general count working not a breakdown of categories.Does anybody know if this is possible? I have searched a see lots of code for setting the category with VBA but none for querying it.

We are having problems with sending back to back emails on one of our web sites. The site is built with .net framework 2.0.We can send the first email without any problems on every try. But to send a second email you need to wait about 20-30 minutes.the problem.One thing we tried was changing the smtp email server. We tried a third party smtp server but the same problem persisted. So I think the problem is not with the smtp server but with our .net code.

This should simply return the window name I.e. "Calculator"But debugging it i get an "OverflowException" on:
strtmp = Space(length - 1)
If I look in the length variable it has "8975925931411505153" in it Why is it so big, and why is it not just "10" for the number of characters in calculator?
