is it possible to communicate with a bluetooth device? I have a fairly simple heart rate monitor which has a USB stick, which connects wirelessly to the monitor.
It utilizes a serial port (COM3), where I can communicate with it. I've tried all sorts of data formats to parse the incoming bytes, from ASCII to INT32 to string... Nothing.
How to read in data from an arduino bluetooth microcontroller? I am new to microcontrollers and I have limited VB experience. The arduino is currently outputting some data to the arduino software screen. I have opened the COM port for the arduino in VB but am unsure how to get the data into a VB string.

View 8 RepliesTrying to read data through the virtual COM port created by bluetooth.
The original console program (and the trimmed version below) was designed to read data from serial port COM1 and output the data to notepad. The program works; hook the bar code reader to COM1, activate bar code reader, swipe card, bar code reader beeps, data input collected from COM1 and sent out to notepad.
The problem: Bluetooth is wanted instead of serial cable.
We disconnected the serial cable, we connected a USB bluetooth receiving device onto the XP. XP installed the bluetooth device drivers 'Generic Bluetooth Radio' and 'MS Bluetooth Enumerator'. Bluetooth detected the bar code reader device and created COM5 outgoing SPP slave and created COM6 incoming.
But now; activate bar code reader, swipe card, bar code reader beeps, NO data input collected from COM5.

On sending data over bluetooth from PC to my mobile(N73), the Input Stream seems to hang up.InputStream is derived from StreamConnection.Does the InputStream have an internal buffer that needs to be emptied while reading large chunks of data?Data is being received in chunks of 10Kb to 15Kb range, and the reading stops after receiving the 3rd chunk.

I have a design question about parsing data in Silverlight. I need to allow my users to validate their csv data (they paste ten rows into a textblock), but I am not sure if I should attempt to do it on the client side where I don't have access to the textfileparser class or send the data to a webservice for validation. If I send it to a webservice how do I ensure the data is secure?
View 1 RepliesCan I monitor the registry for changes similar to how sysinternals process monitor does it in VB? I have checked many different articles and C# samples but not come any closer to getting an answer, I would like to know if there an easier way (a VB sample perhaps)that you folks can share. Ultimately I'd like to be able monitor other things too like file system, processes etc but wonder most about how the registry can be done in VB...Would using system.management be a start? Or WMI? if so is there a nice VB sample..

I am working on a program to turn on devices at times of day and days of week. I am designing it for 15 devices and each device has a file. The problem I have is monitoring all 15 files.

I used data binding to create the files and can display the files one at a time, but I need to monitor the info on all 15 files actively.

actually i have to develop a project to monitor EDI/Edifact data that are send between different EPR systems.Different erp systems means also different database systems. So i have to develop an app to monitor up to 5 tables.These tables can be stored in SQL Server, Oracle, MySQL or DB2. What kind of data access do i have to use ? ODBC ? ADO.NET ?? I actually don't have an idea how to handle this.In the app (i have to write) there should be something like a "DB Configuration for EDI" and there i want to configure if it is SQL, MySQL or what ever that i have to access.In the different Databases all the tables have the same name (means in SQL there is a table called Actlog and in Mysql also a table called Actlog)How can i write my app that it is DB independent ??

I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?
I am using VB.NET and I am designing a generic network architecture in which data can be transmitted in various ways. I am wanting to strip down things as much as possible, and I do not want to transmit in plain text. My question today is regarding ideas and example code (if applicable) as far as parsing binary data that is sent over the wire in VB.NET.I want each packet to have a very generic architecture such as <packet type> <address> <payload> or whatnot. I understand that I can use certain bytes as delimiters for these packet fields. I don't necessarily want to serialize everything being that for security reasons, the same library has to be used to deserialize the data.
a) Put my protocol into binary data where each field is delimited using a certain byte
b) Parse that data from binary at the other end.
Once again, I don't want to use plaintext since this can cause a bunch of overhead in comparison.
