System.Net.Mail Mail.Body Read In From Text File?
Mar 29, 2012I am teaching myself vb.net and wanted to change this code to have an embedded mail.boby from a text file instead of the file attachment. Code spippet below and where I need help is mail.Body = ("tracertALL.txt")
that just puts the name of the file NOT the contents of the file. This code is a CMDWrapper that runs a batch file and I want the contents of a trace route that is pipe to a file >> tracertALL.txt .

Error Using System.Net.Mail?
Dec 1, 2008 I posted the following description before and the only suggestion that I received was to switch to System.Net.Mail code. I did switch and I continue to get the same randow and intermittent error.
Problem: Failure of in-house written VBScript that runs from a web page which calls CDO library to send an SMTP message.
Systems: About 100 Windows XP, Professional, Version 2002, SP2 clients using IE6 and IE7. Symantec 10.1.6.6010. All Microsoft patches are regularly installed.
Symptoms: Web application has sent messages for years without error. About December 2007 an intermittent failure began. About 5% of the SMTP messages are not being sent.
Research 1: Added code to trap error and got error number -2147220973 and error description, "The transport failed to connect to the server".
Research 2: Verified that the failed messages were not leaving the client by using a hardware network sniffer.
Research 3: Used SysInternals/ TCPView to monitor while sending messages.It didn't always show when a message was sent.Perhaps it needs to operate at a lower speed than 1 second. When TCPView did show something it was that ccApp.exe,Symantec antivirus,was communicating with the SMTP server.
Research 4: Reviewed all tools available in Sysinternals but didn't find any way to monitor the messages better than TCPView.
Research 5: Placed error checks throughout the code and proved that the error is in the iMsg.Send command.
Set iMsg = CreateObject("CDO.Message")
iMsg.Send

Apr 24, 2010I want to use System.Net.Mail.SendAync in an ASP.NET MVC2 application. I see that it throws an InvalidOperationException if there is already a SendAsync call in progress. Does this mean only one SendAsync is allowed per host, or per thread? For example, if I simultaneously have 2 web users from 2 different remote hosts, can each use SendAsync at the same time?

Getting System.Net.Mail To Read From App.settings?
Sep 19, 2009In ASP.NET, I can just put my mailSettings in web.config and then ystem.Net.Mail.SmtpClient's default constructor will read them. In a regular VB.NETroject, not ASP.NET, I thought I could just put mailSettings in app.config. HoweverSmtpClient() doesn't appear to read settings from app.config. Is there a step I'm missing in order to tell a VB.NET application to read from app.config?

View 1 RepliesSend Email With System.net.mail Fails?
May 29, 2009I get the following error:Application-defined or object-defined error.From what I can understand, it's when I attempt to attach a file to the email, I get that error. What I noticed is that it's because the file is in use.Is there anyway to attach the file anyway? My users are simply not closing their files after saving, right now I'm using computer manager to kick them out. The process is for them to save a file on a server through a share and then I pick that up and send it. Works fine as long as they close the file after save.

View 6 RepliesVS 2008 System.Net.Mail And Outlook Hang
Feb 9, 2010I am using the System.Net.Mail namespace to create and send email messages. Everything was working fine until a couple of QC members of our team noticed something strange.
If they send emails from within my application and then leave the application open for a while (perhaps working on other tasks on the PC), when they try and activate my application again, it appears to be hung. The CPU is not pegged and everything appears to be normal in the task manager. We narrowed it down and it appears that this issue only manifests itself when MS Outlook is also opened and connected to a server.
I was playing around with process monitor, but nothing I saw was really glaring. I actually started deleting some threads on the PC and eventually my application became usable again.

Asp.net - Check That Email Address Is Valid For System.Net.Mail.MailAddress?
Aug 11, 2011Currently, to avoid errors from being thrown up due to invalid email addresses, I do the following:
Dim mailAddress As MailAddress
Try
mailAddress = New MailAddress("testing@invalid@email.com")
Catch ex As Exception
'Invalid email
End Try
However, rather than depending on Try..Catch, is there a way of validating that the email address will be 100% valid for the MailAddress type?I know there a plenty of regex functions out there for validating emails, but I'm looking for the function which the MailAddress type uses to validate its addresses.
