View 11 RepliesVS 2008 IO.Serialport Does Not Receive Any Data
Apr 6, 2009I want to use IO.ports.serialport to receive ASCII data from an instrument (A Luxmeter for those interested). So far, i've been unable to read any single byte from the instrument using the IO.ports.serialport.A terminal window shows the datastream just fine, and I've used MScommlib to read the data without problems. I just had other problems with the latter, so I thought I'd give this IO.ports.serialport a try.The code runs fine, no errors. It just doesn't receive anything.Bytestoread stays 0 forever.I distilled the code to it's bare essence. What am I missing? Is it something obvious, or did I completely misunderstand the whole concept? (Which is not unlikely..)I did check the obvious, of course: settings, baudrate, cable is connected, instrument is sending, etc.[code]

View 1 RepliesCreate A Code That Can Be Called Apon To Activate But Not Receive Or Send Any Information Through The Program?
Jul 18, 2009I have been developing a calculator for complex math. (Much more complicated than +,-,/,*, and above your usual scientific calculator)Its works quite well .In past programs I have used "private functions". I know that you give them a value and it returns on back. But what if you dont want to recive or send value? My example for this is a function I am attempting to make called "Autopi".The idea of Autopi is that whenever a mathimatical operation is about to be performed textbox(s) are cheked to see if they contain pi. (3.14 or 3.141) If they test positive Autopi will continue pi to however many places have been specifyed in the program. (Currently 300 places just beacuse i can :) Before the Autopi function does this it chekes to see if variable "pi" = 1. If it does it proceeds if it doesent its job is done
How would I create a code that can be called apon to activate but not recive or send any information through the program.And just to clarify what I mean by that is it will read information out of a textbox and write into it.

View 8 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)
VB2008 Send 00h To FFh In One Byte Using SerialPort
Feb 1, 2010peoples The User of my application will enter Hexa values in text boxes (00h to FFh). I need to send these values through the serial port, but so that EACH text box with values 00h to FFh ONLY generate ONE transmitted byte, exactly the value placed in the text box.
Just found examples of this application in VB6, using the following command:
MSComm1.Output = (Chr(Val(txtText1.Text)))
In VB2008, you use the component "SerialPort", and one of the methods for transmitting data to the output buffer is "Write". So I did it this way:Dim As Integer ValHex

View 1 Replies.net - Send And Receive A Large Image Using Tcp?
Dec 19, 2010I need to send and receive a large image between programs running on different machines within the same network.
I've looked at using upd however ran into problems with the size of the packets and
(after breaking the image into smaller pieces to get past this problem) the number of packets needing to be processed all at once - and ultimately packet loss.
I've also thought of sending the image by storing it in a common file folder and receiving it by using file watcher as a trigger. However, this just adds further complexities in setup where common folders don't already exist.
Assuming I'm barking up the right tree looking at tcp, can someone point me to/provide an example of how to send an image file using it (vb.net would be ideal). Also, are there practical limits to tcp package sizes?

Error Tcp Send Receive Application

I'm getting the error with the line opensock2 = New IO.StreamWriter(client.GetStream) saying its not connected. So I seem to need to pass the connection from the background worker to the button click, or have it somewhere else in the code to make it accessible. [Code]
