How can i monitor the HTTP data (headers including raw html data) that is sent and recieved while a user browses with a web browser control in my application?
is there some way to capture the connection itself into a socket?
Is it possible to monitor how much traffic my application has used? I'm interested to see how much data that has been sent and received over the internet from/to my own vb.net application.

View 3 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>

I can add the email and antenna heights easily but how do I manipulate a file browser (file upload) and option input boxes (Antenna Type) from within my vb app?

I use the webbrowser control to navigate to certain websites and login and retrieve some data. For that I created a sub for each website. On the form i have a button that calls every sub when clicked. The problem is that I don't know how to pause or stop the process once started. If I quit the program it will still run in the background until all calls complete. I tried to use a thread, but that doesn't go well with the webbrowser control.

I'm trying to build an application to monitor a site to build statistics from the data being read. This HTML looks like this.
<div id="history">
<h4>HISTORY</h4>
<table border="0" cellspacing="0" cellpadding="0">
[code]...
Now I can read the html and put the text anywhere, I just don't how to read specific parts so I can separate the data out.
I'm attempting to load a website, look through the HTML, and then put it into a control.When I do this, the site redirects to another page. I know how to pull the info, so I need to figure out how to get to my destination page. I'll break it down in steps:
1. Attempt to load www.site.com/1
2. If cookie is not on machine, site redirects to www.site.com/zip code.
2b. Enter Zip code
3. Attempt to load destination site again.
4. Page redirects to www.site.com/default.aspx
5. Attempt to load www.site.com/1
6. Success
If the cookie is already on the machine, it skips to step 3. No matter what, it always loads the default.aspx page first. This isn't a webbrowser control issue, it's a site issue. This happens when on a normal browser.I'd hate to say it's bad coding standards just because it's not working because I want it to, but it sure seems like bad coding standards.

I am constantly receiving 2 lines of data via my serial port, example:
GPRMC, 151243.000 , A, 3723.2475, N, 10354.0208,E,1.26, 290.95, 9.0,,,A*67
GPGGA, 151244.000, 0122.4098, N, 10354.0212, E, 1, 04, 2.1, 71.4, M, 4.3, M,,0000*5F
Apart from the starting 5 alphabets which is the message ID, the other numbers are constantly changing every second. I wish to pick out specific values from these GPRMC and GPGGA and constantly update their respective text boxes, how do I go about doing that?
The 4th, 6th & 8th values of the GPRMC message (in this case '3723.2475' 10354.0208' and '1.26')The 10th value of the GPGGA message (in this case that value is '71.4')
how can i split the recieved data to my vb.net application and then save it, so for example whatever starts with e must be appended to a textfile and whatever starts with a must be display in the label.[URL]..

I created Dataentry forms. In the form there are so many controls like DropDowns and textboxes. I am using Access database. Now I enterd the few records into the controls, and these records are saved into the Database. But now if i enter the any data which i recently saved in the database to the textbox or any other control then the remaining controls should be display the related data.
For example i have 4 controls in my form one is dropdown and 3 are textboxes. If i select the data in the dropdown then the remaining 3 textboxes shows the related data. How can i dispaly the corresponding data to the other controls?

I have the following code that listens to a serial port and writes the incoming data to a listview control (the serial data are a delimited string taht arrives once per second that I parse into separate listview subitems). I would like to be able to close/disconnect the serial port once a specific value in the incoming string is detected. For example, in this case one of the columns of data in the incoming string represents depth, I would like to close the serial port when the depth falls below a given number. I have tried the code below, but my program crashes on the SerialPort.CLose method.

I am writing a small application to see what data I am sending and receiving to my COM port (for a small hardware project based on url..).The problem I want to activate a "Serialread" or "SerialWrite" procedure as soon as data is waiting in the receive or send buffer.I have some basic skills so before I start digging in I would like to get some advice. Can I use a addhandler (I have read something about this on the internet but have to clue how to use it) or something else? Is there a way to check if data is in the buffer ready to be read or write??
View 2 RepliesI am current using VS2008 to write a little app to transmit hex data via the serial port to the target device and receive back data from it and display that on a text box.
The problem i am facing is receiving "read" data "hex" back from the serial port and displaying it. I am able to send data to the target system without any problem. For example, if i send this command "&H10, &H0, &H1, &H7E, &HFF, &H49" The LEDs on the system blink 10 times and it works every time. If i send this command "&H10, &H0, &H0, &HFF, &HD" i should get 5E back and I use Realterm to verify the communication and it works great. When i use my VB app it fails, instead of getting back 5E.I get "&H35, &H45, &HD, &HA" on the buffer

I am writing a program to read data from the serial port using the data received event. But, I realised that My data received event run more than 1 time when there is a data received at the com port and this actually makes my reading command reads the wrong data. The correct procedure is whenever I send a "+++" over to my device. It should responses with "OK."message.
Why the DataReceived Event will read more than 1 time?
