I have a code here to send email, but its shows a error.
Error : The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.
Code:
Dim smtpServer As New SmtpClient()
ProgressBar1.Value = 10
Dim mail As New MailMessage()
ProgressBar1.Value = 17
smtpServer.Credentials = New Net.NetworkCredential("myemailacc@gmail.com", "Password")

I want to send an email using the default email client. If this is not possible, then Outlook will be the client of choice.* I want to be able to send attachments.* I would like to use Read Receipt on outgoing emails if possible.
View 1 RepliesI'm trying to send an email via the SMTP Client. The following line is rejected
CredentialCache.DefaultNetworkCredentials
The intellisense suggests this one:
Net.CredentialCache.DefaultNetworkCredentials
I'm using the System.Net.Mail Namespace...is this the correct one?
Mail.From = New Net.Mail.MailAddress(test@gmail.com)
Mail.To.Add("exc@gmail.com")
Mail.Subject = "Test"

I am trying to get this program to send an email, but still no luck. I am getting the following error that I do not understand. I do not understand what I am doing wrong. Also, I may have an issue that the computer I am writing this code on and trying to send the message does not have ISS and is just windows XP home.
The error is below
System.Net.Mail.SmtpException was unhandled
Message="The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. k41sm2133530rvb.6"

I have an application that takes a series of reports and sends them as attachments in an email to a specified group of email accounts.
When I run the Java version of this using apache commons and the same setting, the email is sent. However, when I run the VB.NET version of the code, it fails on my local machine and on the client machine.
I have a VB.NET web application running on a server that uses similar code. I tried that code locally and it fails. Yet, the web application is working perfectly.
Why is it that the Java application can send the email, but the .NET application cannot?[code]....

View 1 RepliesI am sending an email with an attachment using the following Code
Dim msg As New System.Net.Mail.MailMessage(req.EmailFrom, req.EmailTo)
Dim att As New System.Net.Mail.Attachment("C:Documents and SettingsmichaelrDesktop1216259.pdf")
With msg
.Attachments.Add(att)
[code]....
The file size of the attachment is 396KB, upon the recipient receiving the email outlook shows the file size as 543Kb. Strange thing is if I send an email with the same attachment using outlook the file size is 396Kb.I understand that file sizes can increase due to the attachment being base 64 encoded as opposed to just raw binary.What I am failing to see is why outlook send a file which is 396KB in size but in code when sending it, the same file is 543Kb.
how would i implement a way that i would not hard code the email message that the application send to email recipients? how will i also include email message formatting (text in bold, italic, etc.)?

Is the problem that I need to show "credentials" (i.e. user/pass)? If so, what would those credentials be? Can I use my yahoo email SMTP server with my login info to do it? And is this all I'd need to add to add the credentials?

(before the smtp.Send, of course)

View 2 RepliesWhat I want is to be able to launch an email from VB in the same way that MAILTO: does from a browser. ie. it launches an email from whatever the deault client is.One of the posts on here (linked from the FAQ) mentioned to use MAPI, but the problem is that I can't figure out which 'imports' I need to use.
Googling around I can find lots of excamples of MAPI code, but none mention the imports. If I just paste the code into my VB form it just says that the names are not declared.Another post indicated that these weren't functions from an import, but rather I had to add a MAPI componant of some kind from the toolbox onto a form - but I can't find any MAPI things in the toolbox either...

how to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])

I have got the server app an the Client app Both Working to what i can see But My issue is i was only asked 4 days ago if i could add a Private msg and Whisper Feature as well as admin controls I have Done what i could to it then realised i have no idea how to only send the data to the selected client.
View 14 Repliesi have been working on a chat program Server side and client side i have most of the features i was asked to put in but then once i got most of the bugs out i noticed something the server admin could send whispers and alerts to single users but then when you try do do it on the client side it wont work so i looked through it all and found my issue the user list on the client is only a list of the names in server hash table so i was wondering how do i send the hashtable and all of its data E.G. user connection information to the client so that it can send commands to individual users like the server side can
vb
Public clients As New Hashtable()
' This subroutine checks to see if username already exists in the clients
' Hashtable. If it does, send a REFUSE message, otherwise confirm with a JOIN.

i tried to send the hashtable over the same method used to send the user names to the client but it cannot convert the hashtable to a string so that wont work so my question is How do i send the hash table to the user from the server then display the username on the client ??
