I cannot find a way to get the server to put the information of the recieved packet onto a textbox for the user to see.Client Side:
Imports System.Net.Sockets
Imports System.Text
Public Class Client
[code]....
I am also trying to get the server to send back a packet to the client saying it recieved the packet sent. I just dont know how to translate the packet to a textbox.
I've been using some code which I found on the net, and have noticed that the first byte is never recieved. Annoyingly, this contains the MAC addresses, which is the bit I want. Below is the relevant snippits:
Public Sub [Start]()
If m_Socket Is Nothing Then
Try

I am attempting to post xml to an affiliate and am having some issues. The affiliate will only accept the xml as a string in the name-value pair called "XML" on a classic asp page.
Here is the code file I have, which works fine and gets the response "Invalid XML". I.T. on the other end explained to me that is the message that gets echoed if they get no data on their end from this one statement: XML = Request("xml")
I cant see anything here which would make me think nothing is getting transmitted.
Dim uri As New Uri("http://www.affiliatesite.com?xml=")
Dim packet As XmlDocument = New XmlDocument
packet.Load(Server.MapPath("../XML/TestDoc.xml"))
packet.GetElementsByTagName("id")(0).innerXml = "123"
[Code].....
I'm writing a program which uses sockets, Now the issue I'm having is, If the packet received is over a certain size, the socket then fails to receive anymore packets/data after it.

This show the empty space where it auto-scrolls to when writing the received string to the console.
This shows the actual received message (a bit edited with time, etc ...)

View 1 RepliesI am building a simple proxy in server vb.NET and so far it has been successful, but then whenever i receive data from the internet and write it back to my browser's network stream using NetworkStream.Write the received data tends to come up slowly to my browser due to reasons i do not know of. But when I chain my application to another Proxy/listener on my local computer (e.g Privoxy), data seems to come up very fast to my browser. If anyone has an answer to this I would really love to know.btw here is the part of my code {subroutine} that receives data and forwards to my browser.
Public Sub ForwardRequest(ByVal Client As TcpClient, ByVal ClientMessage As String)
Dim Browser As TcpClient = Client
Dim BrowserStream As NetworkStream = Browser.GetStream

View 1 RepliesI need to write a program in VB 2008 express that takes an user entry from a textbox and strips out all the spaces, changes it to either all upper case or all lower case then checks to see if it is a palindrome. I must also include a loop structure and a decision structure. I have seen bits and pieces of code but I do not really know how to put them together. Basically I need it from the button click to the end. ?

View 3 RepliesI took a look at System.Security.Cryptography.MD5 class about using a checksum for a UDP program i am making.Basically i want to use it, to ensure the server is receiving what the client sends it, in a way that the server can make note of it receiving properly without having the client keep track of how many proper payloads the server received. The reason i need a checksum is because the client is sending a random hex payload, so i cant have the server predict what it should receive the same way as i have it working with the sequence number.I dont fully understand how i could implement this to my code. I believe i should make a public property in my packet class, but im having trouble implementing it with the way i coded my program. [code]

View 2 RepliesIn my serial port application, I have my code -
Private Sub SerialPort_DataReceived(ByVal sender As System.Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort.DataReceived
Dim cnt2 As Byte
[code]....
For some packets I sent, "Error Data Received" came up. I checked BytesReceived, it was 0. My question is: since SerialPort_DataReceived processes data received, data was supposed to be received. Why the number of bytes I read was zero? BTW, when is this event accessed? it is accessed when any number of bytes received or the whole packet received?
I've been trying to publish some software for 2 days. At first, I received an error about frontpage extensions not being installed so I installed them, only to screwup the ht.access file on my site and lose my web site for 5 hours.
I had an email this morning from Lunarpages saying they installed the extensions, recoded the ht.access and even tested frontpage on it. SO -- I tried again this morning and still received "the components for the frontpage extensions are not installed". ?
AND --I must be missing something and looked everywhere in VB.NET (options etc) but how in the heck can you publish something directly to your website (I used the wizard and setup all the publish options) and NOT be prompted for your user ID and password? Obviously, VB.NET has it's own ftp program.

View 5 RepliesI am using Visual Basic express to create a serial interface to a multi-room audio controller. I have started by creating a form that can connect to the controller and I can receive data from the Controller and display Zone status, volume etc in corresponding texts box thaks to help from Stanav and Tassa in my previous thread.
My next problem is to do with receiving lots of data from the serial port and my application getting out of sync. This is mainly caused by turning the volum control as each time it is turned a little bit the controller sends out the new status of the Zone being effected
eg
****Turning Volume knob on Zone 1***
Status returned from Controller:
#Z01PWRON,SRC3,VOL05<CR>
