Read HDD Serial In Vista?

Mar 20, 2009

I have a class which reads the serial of the users HDD, basically so I can generate a unique license for that user based on HDD serial and other things.

This works fine in XP where UAC isn't an issue. However, when run on Vista it pops up security warnings and won't continue unless you turn UAC off!

Is there a "safe" way of reading this information without Vista throwing its lunch up?

VS 2010 Serial Read And GUI Update Is Slow?

Jun 17, 2010

I`m trying to write a small program which connects to a serial port at 115kbps and reads a stream of continuous bytes from a microcontroller. The program should then graph these bytes by time. Ideally this all happens in "real time" and as quickly as they can be sent.With a 50ms serial write delay on the micro the VB program keeps up fine, but if I lower the delay any further, say down to 1ms, the update can`t keep up and the serial buffer just grows.I wasn`t expecting the bottleneck to be the PC side so it`s likely my code is doing something wasteful. Or maybe it`s the graphics which are drawing slow?

Private Sub DrawGraph()
Try
Dim y As Integer = m_Y
Do

C# :: Read Serial Port Control Line States With .net?

It is my understanding that it is possible to use the control lines on a serial port and read whether the switch is closed or not. I've found a schematic of how to connect the switches to the pins, but I have not been able to find any example code on how you can read the state of the switches.

Cannot Correctly Read Bytes From Serial Port Consistently

Jun 4, 2009

I have a timer control that sends data to a hardware every 3 seconds. I sent 6 bytes of data. In return  I am expecting 8 bytes of data in DataReceived event. First time I send 6 bytes of date, in DataReceived event, I get the expected 8 bytes. Then in next 3 seconds, again the expected 8 bytes of data is received. But after that I find that DataReceived is fired 2 times: first time I get 6 bytes and then I get 2 bytes. After that I again get 8 bytes as expected. So in short, 2 times I get 8 bytes as expected and 6 bytes and 2 bytes and again 8 bytes. This pattern is repeating continuously. Why? Is there any reason why I cannot get all 8 bytes everytime? Note that the code is in vb.net 2008

Code in button btn_Start () 
'Set serial port parameters
x.PortName = "COM1"

I am at the point in my code where I know that the device is sending 1056 binary bytes of data. How do I go about storing this is a binary array? After I have the array stored (which I dont yet) I need to go through the array and convert the binary to integers. They are 2byte integers in the format: 8bit MSB|8 bit LSB.

Serial Read - Program To Display Position In A Textbox?

Dec 31, 2010

I'm working on a project that incorporates an Arduino Duemilanove board and a program that a wrote in VB 2008. Basically, when the Arduino receives a symbol from COM3, it sets a Pin on the board, high or low. I'm using two Pins, one is going to be for a laser, the other a relay. The relay is going to close a circuit, and act as the button on the Nerf Vulcan. That's right, I'm creating a Nerf sentry gun.It's going to be fully controlled from my computer. I have all of the code done for the servo, and all of that, both on the Arduino and in VB. 

 The Arduino sends the angle of the Servo that will control the right and left movement of the gun through COM3, every time it changes. I want my program to display that position in a textbox, as my program needs that value in order to properly function. Basically, I need the code to read from the serial port, and display what it receives in a textbox, textbox3.

Timer Tick Event And Serial Port / Read And Display Live Data?

Jun 21, 2009

[code]...

I have a quick question regarding the serial port and timer tick event. Basically i have a micro processor connected to the PC via the serial port. With a baurd rate of 38400 set.When the PC sends the micro ":K + VBCRLF" the micro response with a string of information (ASCII encoded) and delimited with a "," and at the end of the transmission   a cartridge return line feed is added.Example of sent string:

"12,1134,123,545,76,6868,34,232,1,2,3,6,7,8" These numbers are then split using the VB mystring.split(",") function into an array of strings, then the  numbers are converted using ctype. After which my UI is then updated.I have Witten the code in a tick timer event using a timer count of 300ms. Although the program runs and the UI is updated i end it with lots of exception errors. I think allot of this is down to the serial port either timing out or not reading complete string.Or possibly the timer has not executed all the code before another tick event happens Even after adding a few try catch statements i am still having problems. Can anybody suggest a better way of doing it?I was thinking of using a do while loop and at the end a sleep function instead of the timer tick event.I need the speed as i am trying to read and display live data.
