Create A Program That Just Listens To A Range Of UDP Ports?
Mar 19, 2009
My goal is to create a program that just listens (no locking, no blocking, just listens) to a range of UDP ports (coming in via the internet) on my local machine and copies the traffic to a richtextbox.I have various programs that say they use the ports and I simply want to listen to what the ports have going through them, I need to make sure that the messages are still processed by the applications that they are supposed to be as well.I will NOT be sending anything. Here is the code I have so far, and yes I know I only have it on one port for now. Figured get one to work then worry bout the rest!
Option Explicit On
Option Strict On
Public Class Form1[code]..........
I have recorded as using this port is running and receiving messages...
I'm experiencing a weird problem. I need to create a Windows service that listens to a port for data. The data is comma separated, so I need to split it up and just write a few of the separated values to a file. This is a brief summary of my code:-
Do While True
tcpClient = tcpListener.AcceptTcpClient() networkStream = tcpClient.GetStream() Dim bytes(tcpClient.ReceiveBufferSize) As Byte
[code]....
Now the above code works fine. But suppose I just want to write only (2) to file i.e 2 of the comma separated values, problems arise. This is what happens:-
If I include both lines (1) and (2), output file = lines (1) and (2) If I include only line (1) and comment out (2), output file = line (1) If I include only line (2) and comment out (1), output file = BLANK ???
im trying to make a program that only listens to a few keys that the user presses, and if one of them is pressed, it carries out a specified command.for example, right now,i found a keylogger that could carry out my command, but id rather use something else if possible. right now, i have a timer running this:
For i = 1 To 255 result = 0 result = GetAsyncKeyState(i)[code]....
Then, in the textbox1_textchanged, i search for like if textbox1.text.contains("M") or something.problem with this, is im pretty sure its a keylogger, and i dont want to have to have that. also, it does not work in vista.
Found a solution! (should have researched more throughly!) Option Strict On Imports System.Runtime.InteropServices[code].....
able to open and utilize a single serial port within with my VB 2008 program (i.e., set port parameters, open&close port, send&receive data via port, etc.), but I want to open two or more serial ports concurrently within my VB 2008 program so that I can read data from one port, say COM1, make decisions and calculations based on that data, and send instructions out through another port, say COM2.
I am looking to write a program that runs in the background that monitors the USB ports on a PC. If a specific device gets unplugged I want a message box to come up saying so. Is this possible. I am guessing I would need to query the usb devices for their ID and then write a simple If then statement, however I do not know how to get the IDs of the usb devices.
Is it possible to make an app (with VB.NET or any other language) that actually listens to real FM? not internet radio, or XM Radio, or any of that, but actual (Signal) FM radio, the type you listen to in a car or with a radio? if it's possible, is there any special hardware that's needed? I mean, if i wanna make it will all the consumers be able to run it? or only a selected few? Im sorry if this question is too long...
And is radio dead now or is that what people say? Am i the only one that stil listens to radio?
disposing http listening object when program closed which located other file than my main form.I am starting http listener like this :
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load WebServer.Main() Klasör = "C:UsersSalihDesktopWebServerWebServerWebServerinDebugWWWRoot" Sayfa = "index.html" End Sub
I've found ways to read from a .txt file into Excel, but (having created and loaded an Excel sheet via vb.net 2008) I want to do the opposite which is to read each cell and row into a .txt file csv format like this: "Surname","Andrew","2","Mr","Hon.Member","PERCUSSION" I guess I need some way of knowing when the last row of data ends. Once in a .txt file I can load data in a variety of ways into several ListBox/s and labels without loading and reading the original Excel file.
So i want to create a program (or specifically a part of a program -form?) that will be able to load a xml file.I have managed to save an xml file from a xlsx workbook, i want the program to be able to sort each column either by it's value if is a number or by it's text if it's a text , i would also like to have a range sort so the "program" will only show results from a specific range
I am working on doing a Copy and Paste in Excell. I need a way for the user to input the range for coping form the first sheet. So I created two text box. But now I can not figure out how to combine the text box values as to create the range. Here is what I am woking with.
Private Sub BUILD_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BUILD.Click Dim moApp1 As Object
I have an MSAccess 2007 DB to record our employees Personal Days Off (PDO). Until now I have only had a form to record each single day taken. This results in time consuming repetitive entry when an employee takes multiple consecutive days or weeks off.
My database consists of two tables:tbl_PDO (to hold the Worker, DateTakenOff and TimeTaken) tbl_Employees (containing the Employees contact info, Name, Address, etc.) A form for Single date data entry with tbl_PDO as the record source and the following fields: (This is the original entry method one day at a time and works as it should)cboWorker(with Record Source tbl_Employee[Worker] DateTakenOff(ShortDate) TimeTaken (in hours) A form for Date Range entry with tbl_PDO as the recored source and the following fields: cboWorker(with Record Source tbl_Employee[Worker] StartDate EndDate TimeTaken (in hours) I have been trying to work with bits and pieces of code Ive found online to create multiple rows in a table based on a date range.[code]...

II am trying to create a toggle button that switches a list to a range and then back to a list if needed. I am able to get it to do both but when I add an item to the list, convert to a range and then convert back to a list it leaves off the last items I entered.I tried to work in a code to select all cells but I must not be putting it in the right place.This is what I have so far:
I am using the following code in the Load method of a VB form to generate random numbers in the range 1 to 8. Without fail after enough loops the range is exceeded and 9 is the random number returned every time. The line using the Rnd function is from: Rnd Function (Visual Basic)
I am getting the error:"Range variable 'sender' hides a variable in an enclosing block or a range variable previously defined in the query expression."for this
Imports System.Data.SqlClient Imports System.Linq Public Class Form1
[code]....
I can select any other item from the table without the error. "sender" has the same properties as "receiver" in the SQL table.

I am very very new to VB.NET and would like to ask a simple question. I want to create a vb.net program and allow visitors to a website to download this program. However, I prefer not to have visitors download a zip folder. I would like to have a program that just gives a prompt to save in a selected folder, once the saved file is selected it prompts the person to download, and then when finished prompts the person to run the program. The reason is twofold:
1. I don't like the extra step involved with unzipping the file. and 2. I don't like the visitors having to look for the "main" file program within the new downloaded folder. So is there any way to have just one file for others to download without having it in a zip folder?
