Sending Bytes From The Serial Port?

Aug 30, 2010

I'm working with a device using the serial port and i am sending a command from the pc to the device like this:

1. I Change the parity to mark

2. then send a byte

3. then Change the parity to space (here is the problem)

4. Send a lot of bytes

but the device just ignores all the last bytes, im pretty sure its a timing problems, so a timeout occurred attempting to send a command, how can i change the parity without losing time?

Sending Hex Data Through Serial Port?

Mar 1, 2010

I am trying to send a command through my serial port to a external device. The format of the command frame is, more or less, like this:

'0x0A 0x03 0x20 0x00 Checksum'

What I've written on my code is just this:

VB code
num_dec = &HA + &H3 + &H20 + &H0
checksum = DecToHex(num_dec) '2D
data=&HA & &H3 & &H20 & &H0
SerialPort_RFID.Write(data & checksum)

The problem is that when I stop the program on the Serial...Write line, I see that the data I sent is on integer format instead of Hex format.

Sending / Receiving Data To Serial Port

Aug 13, 2009

I'm trying to control a serial port device that both send and receives data. I can receive data quite happily from the serial port but I don't appear to be able to send data to the device. The device works perfectly as I can test it using putty, I open putty select serial and select 1200 baud, the device immediately lights up and can send and receive. However when the port is set up and opened in VB the device doesn't light up so I can't send data to it but can receive data from it. According to the instructions I need to send either ASCII 'X' Hex '$58' or Decimal '88' to make the device ready.

Code (VB Studio 2005) :-
Public Sub New(ByVal synchronisingObject As ISynchronizeInvoke)
ComPortUsed = My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINESoftwareNJB", "COMUSED", Nothing)
PricePerTrack = My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINESoftwareNJB", "PRICETRACK", Nothing)
Me.synchronisingObject = synchronisingObject

Sending Data Into VB Through A Serial Port On Computer?

May 2, 2009

I am sending data into VB through a serial port on my computer, from a microcontroller. The data enters VB in an ASCII form, but I need it as a number. I can use the Asc command to convert numbers 0-127 however after this it dosent work. I believe this is becaus the ascii character map only goes through 127. So how can I convert the rest of the data (128-256) to a numbers?

Sending/receiving Serial Port Data?

Feb 22, 2011

Opening and closing the port works fine, and as far as i can tell, the serial.write("blahblah") should be writing to the output buffer, but I am unable to test or verify this by reading it in. the commented "Receive data from serial port" and subsequent DoUpdate() function are where i am having trouble. It doesnt seem to actually be reading in the data if it is in fact writing it correctly.

VS 2008 Sending And Receiving Data Via Com Port?

Aug 16, 2010

I have a very basic knowledge of coding, just enough to understand some PicBASIC Pro and program a microchip to send the values of some variables to a PC via the com port. I've used a terminal utility like Hyperterm to confirm the right variables are being sent, so I thought it would be cool to have a custom application on the PC to display these variables, and possible set them via the application by writing the new one back to the PIC. So I downloaded VB express 2008 - and whilst it was "simple" to draw a box and add a few text boxes I'm lost at how to actually do anything practical with it

[Code]...

Could someone advise me in laymens terms exactly what I need to do inorder to populate the text boxes with the data from the PIC micro. Whilst I understand the basics about BASIC, I have no idea on things like classes etc

Dead Simple Example Of Sending Hex Data To A Serial Port?

Jul 6, 2011

I ran into this problem while trying to write a Pan/Tilt/Zoom controller program. I found some very complicated examples, but managed to put the pieces together into this simple test program.I first import System.IO.Portsthen I define a new serial port and give it the required parametersI open the com port when the form loadsI have two working buttons, one to pan left, one to stop panning. The hex commands are pre-configured.The one for Stop is A0 00 00 00 00 00 AF 0FThe one for Pan Left is A0 00 00 04 14 00 AF 1FI declare a byte array to contain the command bytes and put them into the correct position.

Code below:

TCP Protocols - Sending Command To Specific Port On Same Computer

Mar 10, 2011

I am working on writing a program that needs to send a command to a specific port on the same computer, I have that working fine. There is another piece of software running that is listening to that port for some commands (read on).
Dim myTcpClient As New TcpClient
myTcpClient.Connect("127.0.0.1", 61225)
Dim networkStream As NetworkStream = myTcpClient.GetStream()

However when I try to send a command I get no response...
Dim outStream As Byte() = System.Text.Encoding.ASCII.GetBytes("0x33")
networkStream.Write(outStream, 0, outStream.Length)
networkStream.Flush()

I have been given a list of protocols that I need to send to that port. What I have been told is that the size (in byes) is 1 and the value is "0x33" with no parameters. I am completely new to sockets and sending data through tcp.

Asp.net - Export To Excel File As .zip To Reduce File Size - Compress Xmldata Before Sending It To The Client?

Jul 8, 2010

I like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.

May 27, 2012

I am trying to Send an Email with an attachment (using Gmail) but I keep getting errors like "Operation Timed out" or Failure Sending Email".

Here's what I have (Portion of it):
Private Sub SendMailOneAttachment(ByVal un As String, ByVal pass As String, Optional ByVal smtp As String = "smtp.gmail.com")
Using oAttach As Net.Mail.Attachment = New Net.Mail.Attachment((Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) & "\" & My.Computer.Name & "_" & fName & " .zip"))
Dim client As SmtpClient = New SmtpClient(smtp)
