Communications :: Simple Send Text/files With IP
Aug 31, 2008
So ive looked everywhere but every example i find doesnt work on visual studio 05 and doesnt convert properly. I simply want to send info from one computer to another through direct connection. if anyone could point me in the right direction it would really be helpful. most stuff i find seems to be more complicated than what im looking for.
then just one other question. both computers will be going through a router. as long as i have the port im using forwarded on the hosts side, that shouldnt be a problem, right?

I'm using the following code to send simple SMTP mail. the code sends successfully on the development PC however, as soon as i move this to another environment (another PC) the message delivery fails..
Observations:
>> Locally I'm using a version of .Net (2.0.50727) (under application properties > references)
>> The remote machines for which this is failing on has various version of .net 1, 2, 3
>> I'm using the VS2005 and publishing with the wizard
>> Used a packet sniffer to monitor the network interface connected to the network and the no traffic is being generated by the source/sending PC.
Imports System.Net
Imports System.Net.Mail
Code:
Public Sub SendEmail(ByVal Email_To As String, _
ByVal Email_CC As String, _
ByVal Email_From As String, _
ByVal Subject As String, _

I am using VB2008 Express and am curious how to send a command via RS232 communications. The string that I need to send is 02h PON 03h. The start and end bits are 02h and 03h.
How can I convert 02h and 03h to its ascii form. In hyperterminal, I use the sequence {(hold)ALT 0 0 2} on the number pad to send the start bit.
I am using this code currently without the start and end bits

I'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)

What code can I use to send a simple text file to someone else's computer and choosing a save location and vice versa from theirs and loading it into a rich text box in their application that they have open, and vice versa? Their application is the same as mine (sort of like how an instant messenger works-except it does not save, send, and load text files like I am aiming for)

I've been playing around with the TCP client/server sample code I found on [URL] but I can't seem to get it to function correctly. The problem I am having is that if I try to send data from the client a second time I get nothing back, not even an error that it couldn't send data. Every time I run the project it works the first time but that's it. When I was running the code line by line it seems to get to 'networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))' and then it jumps over the rest of the routine.

I have quite a bit of VB6 experience but now am trying to create my first VB.Net project. The project is very simple - it just needs to send 8-10 character strings from the PC serial port. The problem I'm seeing is that VB.Net is always sending out a 0x0A character after each 'WriteLine' call. Using VB6 it was necessary to manually send out any End Of Line characters. My application requires that no extra EOL characters be sent after the string.

Need to design a program that can encrypt and decrypt messages stored in simple text files using a private key stored in a separate file. Software should also be able to allow the users to enter simple messages that either displays the encrypted or decrypted message. The encryption method should use a simple substitution method. It should be set out in the following format:
Example (the "@" is the separator):
@
The character The Code End of line
A @ 4gh EOL
B @ 84!9 EOL
Has to use the 256 ASCII character codes. The separator will be used to separate the character and its corresponding code.Here are the pseudocodes I have come up with:
� Read any private key file
separator = readline(file);
while not EOF(file) do
tempStr = readline(file);

I 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)

Basically, i don't want to use <input type="submit"> mainly because it's a button, i'd rather user ActionLink, so i am using Ajax.ActionLink, and i'm not sure what to place in the routeValues argument for it to pickup the new (edited) data (user enters comments etc) and send it to my action.this is what i have, but of course, it sends the original comment before user edit back to the server/action :)
<%= Ajax.ActionLink("Update", "UpdateComment", Model.Comment,
New AjaxOptions With
{.UpdateTargetId = Model.CommentDivId, .HttpMethod = "Post"})%>
ps: i know how to do this in javascript, and doing ajax posts etc,

How can I create a simple application to send timed controls to an external device?
What I need is to create a very simple application that sends control signals or voltages out to an external device connected via serial perhaps. The external device will in turn trigger some electromechanical devices. There needs to be 24 independent controls each with a simple command equivalent to on or off. What is important is being able to control the timings of the on and off on each control.[code]....

I am trying to use the send keys function to send text to another program.I ahve gotten it al working well, except for using () as I know sendkeys doesnt like these.I have tried using the Replace function in several places in my code to replace the ( with {(} and {+0} etc, with various other options tried.But when I run the program, it seems to skip this out completly and leaves them in the string as (, and therefore it errors and wont run.When I step through it, it goes through the function but doesnt alter the strng as it should. This is the code to send the string and my attempt at making it replace the () in the module
Module TextReplacement
Private Declare Function GetAsyncKeyState Lib "user32.dll" (ByVal vKey As Int32) As Short
Dim counter As Integer
Dim sData() As String
