I want to create a program that will keep track of the amount of (network/internet download) data that has been received, but I have know idea how to go about doing it.Where would be a good place to start with this type of development? Or could some one give me example code that will get me started.

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 RepliesWell first off let me say I am not sure if this should be in network or game programing but I think network programing is more relevant.
Anyway
I am creating my first game that runs over a network and so far everything is working. I have a server program, the clients can connect and see each other flying around. (weeeee)
However I have hit a wall when trying to make them shoot. The most easy way I can think to do this, is to have the client tell the server �hay i need a bullet pointing at x angle moving at y speed� the server then spawns a bullet entity then sends a spawn entity packet to all the clients. The main problem I see with this, is that the clients gun will have a delay based on latency.(funValue -= 1000)
The only other way I can think to do this, is to have some fake bullets spawn on the client but when the client gets the spawn bullet packet from the server, I am not sure how to keep track of what fake bullets to delete.
I was just wondering if there was a way with, using VB.net, be able to create a program to detect when a message is received in Windows Live Messenger, and alert the user?Essentially, MSN is minimized in background and our program, Program A, is also running in backgroung.Friend X sends us a message, the MSN icon blinks as usualy, but also a window pops up and shows the name of the user and the message.I was just wondering if there was a way to connect to MSN in some fom to be able to do this?
View 1 RepliesVISUAL BASIC 2008. Program Description: Create a program that calculates the amount of quarters, dimes, nickels, and pennies are needed from an amount of change (entered in pennies). The program should use the largest coins possible (for example, fifty cents should use two quarters, not five dimes, fifty pennies, etc.)
I don't want the code already written out, I need somebody to walk me through making a code. Also, this is my first class dealing with computer programming so all we've learned so far is declaring variables and how to label objects, the simple stuff. I'm at a loss at how to start because a quarter is worth 25 but the program is supposed to show how many quarters once a user enters the amount in cents.
I have to create a program that ask the user to enter the amount of hours work for 5 diferent projects in textboxes. The user have to enter the time he worked in minutes. Ex: 153, 280, 600, 130, 20... The total then is out putted into a textbox in this format "13 Hours and 35 Minutes" I'm having dificulties making the conversion and the separation from hours and minutes. I understand that the total is divided by 60, but if we fallow the above numbers the total hours comes out to 1183 / 60 = 19.71. So I'm having problems with the .71 mnts or digits... so from this total I have to output the total of in this particular format: "19 Hours and ?

View 3 RepliesI have created a little program that helps me keep track of tons of data by inserting it into sql. I created 5 forms and all 5 can insert data at the same time, but mostly just 1 of these is working continuously. I have noticed that the program will run, then at random times it will stop responding (can't minimize/click on anything/data entry stops), and the only way to stop is to kill the task. I can't even click in the debugger to set a break point when it happens, and setting breakpoints before debugging is useless as the program could run 2 hours and stop, or 10 minutes and stop. 5 forms, they open different excel files, insert data into sql, and repeat.

When i try to get half dollars to work it rounds up and then the rest of the coins say 0. How should i do this?
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>

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')

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 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
Private Sub sendbutton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles sendbutton.Click
Dim send_Buffer() As Byte = {&H10, &H0, &H0, &HFF, &HD}

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?
