I'm very new to VB and .Net. I'm using VS Express 2010 to write an application, so far its great and I've managed to get everything working they way I want it. I'm now trying to add more advanced features, (e.g the app has some TextBox's that the user enters required information and it generates an e-mail based on a template I've coded. At the moment this just copies it to the clipboard and the user can create an e-mail and send it manually.)
I want to add the functionality for the app to automatically open up an Outlook mail and pre-populate all the information, I've managed to get this working for Outlook 2010. I done this using the following codes.
Dim MSO As New Microsoft.Office.Interop.Outlook.Application
'Create a new Message object
Dim msg As Microsoft.Office.Interop.Outlook.MailItem

I am trying to send more than 1000 emails by using gmail host.It was sending only 158 or 160.I am serching for solution in google.In google I found some articles which has described that we cant send more than 200 mails by using gmail host and some articles said we can send more emails using Thread class.I am using vb.net(visual studio 2005) for developing sites.
View 6 RepliesI 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.

Imports System.Web.Mail

[Code].....
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 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 have written a little code to send email using System.Net.Mail.SmtpClient based on examples that I have found online. The code takes e-mail address, subject, body text and even attachment from my form, send the e-mail and sendsme a confirmation.
Initially I had some problems because I was using async but when I reverted to simple send it worked great.
I now have a need to send multiple e-mails (purely legitimate use - newsletters & information updates to registered clients). My solution was to loop through a dataset passing the necessary variables (e-mail address, clients name & personalised body text) to my e-mail routine. It sort of works but I repeatedly get a delivery failure message "The Operation has timed out"
