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'm trying to create an application that sends an email to an smtp-server. The server is not set fixed, but will be looked up according to the domainpart of the email-address where the email should be sent to.
[Code]...
It would be quite useful, to know if the message was accepted by the mailserver and the message was successfully sent. What I am able so far is, that I can get the SMTP-Server error code (if there was an error (StatusCode 5xx) by using the System.Net.Mail.SMTPClient Object and its SendAsync Function. There, if there was an error, I get an Exception-Object in the Callback-Event of the SMTPClient
I'm well aware that not every mailserver will tell me if the mailaccount truly exists and then reject my mail with an errorcode but instead just accept the message and then delete it. Therefore I would be grateful for another Method to check if the mail was sent (note: not read, that would be the read confirmation)
The final purpose would be: Try to send an email to a recipient using it's domains mailserver and if it fails, proceed according to the errorcode (user does not exist -> abort / mailserver did not respond -> use another mailserver if available).

View 1 RepliesI have a piece of code which sends email with an attachment from my application. The code uses MAPI to send the email. It opens up a new email message so the user can add to the email message, and then the user clicks send.The code works fine. However there is one small problem. The email that the code opens, is always in Microsoft Outlook. Sometimes the application's user has Outlook Express set up as the default client, but my application always opens the new email message in Microsoft Outlook. (Outlook 2003. In the one user's machine that has Outlook 2007, everything works fine and the email opens up in Outlook Express.)As I searched for a solution, I saw this problem posed many times in various places on the Internet, with no solution (or none that worked). I did try several suggestions which involved creating registry settings and registering some dlls.

From what I can tell, this should be configuring some kind of sending option. I can kind of work out what's going on, but I don't know how I should go about re-implementing it.It's looking like the place to be putting this stuff is now in the System.Net.Mail.SmtpClient.Credentials class, but the information in there doesn't seem to bear any resemblance to what I have here.I'm almost certain I'm making some obvious error, here, but I can't see it. Can someone tell me what I should be doing?
