View 1 RepliesSend Plain Text Via Sockets In .NET
Sep 9, 2011I'm writing a replacement for an old library we use at the office to communicate with a rather clumsy and old custom-made C++ framework that takes requests via sockets in order to communicate with a bunch of other systems. The problem is that it will only take plain text messages containing a string which must be formatted in a very specific way.The problem I'm facing is that I haven't found so far a way of sending plain text through the socket. The Send method of the socket will only take byte arrays, and while the listening point receives the data, it gets there completely scrambled, and there's no way I can mess with that in order to convert the byte array back to plain text. I need to be able to send plain text, not byte arrays.[code]
View 1 Replies.net - Different Increase In Email Size Using SMTP Class To Send An Email As Opposed To Outlook?
Jan 6, 2010I 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.

View 2 RepliesEmail & SMTP - Program To Send Very Simple Text Email Messages
Feb 17, 2009I'm trying to get my program to send very simple text email messages. I did do a search beforehand, and found that I was having the same issue as someone else, but the specific question I have was not answered --
I've learned that if you're trying to send mail, you need an SMTP server... I found this list here but every one of them I've tried yields the same "Failure sending mail" error.
Here's my
Dim mail As New MailMessage()
mail.From = New MailAddress("me@mycompany.com")
mail.To.Add("destination-email@whatever.com")
[CODE]...
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?
smtp.Credentials = New NetworkCredential("MyUsername", "MyPassword")
(before the smtp.Send, of course)

View 1 RepliesCommunications :: Socket Behaviour - Created A Client That Can Send And Receive Data Via TCP Sockets
Aug 26, 2010I have created a Client that can send and receive data via TCP sockets. The objects stored on the serverside are the *exact* same object used for the client. They use the same send and receive protocols.
Now, when i send a string from the server to the client , it does precisely what it should do. However when I send a string to the server.... I do receive the string as an equal length of NULL characters. I run the server and client locally.
Basicly what can influence the behaviour between two completely identical objects performing the exact same task? I wonder if there is some socketflag issue if the TCPlistener.accept function returns a completely different setup then the one I R used to.
(if it is of any interest, the send protocol is asynchronious)
2005 - Discard The Contents Of A System.Net.Sockets.Socket Send Buffer Using TheSocket.IOControl(IOControlCode.Flush
Jun 10, 2012I'm attempting to discard the contents of a System.Net.Sockets.Socket send buffer using theSocket.IOControl(IOControlCode.Flush, .... Does anybody know whether VB.NET supports this command? I've tried supplying 'Nothing' and 'Nothing' for both required parameters, also empty and populated byte arrays in combination with 'Nothing' for both required parameters, but I consistently get an 'Invalid argument' exception. I've tried a web search for an answer, but the only mention I've found was a question asked about 8 years ago, with still no answer.

Sockets - Check That If Another Computer In The Network Send Some String Data To The Listener Computer?
Mar 19, 2012i have a task to create a TCP Server (a program that is listening on its network card interfaces for incoming data stream).I have search on the internet and i found that i can use two methods : Socket or TCPListener class.I have created an example for Socket class, but i wondering how could i test it? I need to check that if another computer in the network send some string data to the listener computer , then this message should be displayed.Here is the example from microsoft that i am using for TCP Server using Socket:
Public Shared Sub Main()
' Data buffer for incoming data.
Dim data = nothingc[code]....
But it does not work because of the PORT setting.If in the TCP Server i have "Dim localEndPoint As New IPEndPoint(ipAddress, 0)" the client crashes, but if i change the port from any (0) to 11000 for example,the client works fine.Do you know why?
Later edit2:Maybe i should have started with this question:Which method is recommended for my scope?asynchronous or synchronous method ?
