Detect When A New Usb-device Is Connected?
Mar 27, 2009I want to detect when a new usb-device (can be anything) is connected to the computer. I don't need to know what kind of device it is, I just want to know when it is plugged in.
I found this thread: [URL]
I know the solution is in here, but I'm overlooking it I'm afraid. What I want:
USB-device connected > Run function. USB-device disconnected > Run another function.

View 7 RepliesAccess A Connected Zune Device?
Aug 10, 2010I was just wondering if you could view the items on a connected Zune device (such as the Zune HD or any of the others. (4GB, etc.))Also, possibly listen to the songs / watch the videos on it with the Windows Media Player codec in the program, and view the pictures in a PictureBox? Is this possible at all? Can I at least view the items? Or is this strictly forbidden?

Send Command To Device Connected To COM1?
Feb 3, 2012I want to send a simple command, such as "v20" followed by a carriage control character, to a heating/cooling block connected to a desktop computer running Windows XP. I am able to get the commands to work within a terminal emulator. I want to compile a simple program that will be executed by software used to control a liquid handling robot.I've looked at the how to send strings to serial ports in visual basic page and modified that code ever so slightly to send the data that I want. However, it does not work and my heating/cooling block is not changing temperatures.
Here's what I have written:
Sub SendSerialData(ByVal data As String)
data = "n65"
' Send strings to a serial port.

C# - Find Through Which Network Device User Is Connected To Internet?
Apr 1, 2011Using the code below i will get all network interfaces wich are enabled and functional on the machine.

But my problem is how to get the default one, the one(ethernet adapter) through wich user is connected to internet?I need to change some settings of default(through wich user is connected to internet) adapter. settings i change through registry so i could sample add same settings for each network interface but that could cause problems and makes no point then?
EDITED:for now i have done like code below, so if this can help someone other...
Dim u As UdpClient = New UdpClient(System.Net.Dns.GetHostName, 1)
Dim localAddr As IPAddress = CType(u.Client.LocalEndPoint, IPEndPoint).Address

File I/O And Registry :: Detect A Mobile Device Has Been Connected To Pc
Jul 20, 2009I posted the message below in the VB6 section of this forum with no success, but as I've now got access to VB2008 via work, I thought I'd try again here. Basically I'd like to be able in code navigate to a folder held on a mobile device like a mobile phone connected to a pc using MS Activesync? It shows up in the drive list within "My Computer" as a system folder, I've vb6 code to detect all the drives including network mapped drives but not the mobile device.Ultimately I'd like to do file copying when my program detects a mobile device has been connected.
View 1 RepliesVS 2008 Program Autorun When Removable Device Is Connected?
May 18, 2010I'm not sure if this would be this right place to post this, or even if I should go about trying to do it through my program itself or through the computer's settings on the final EXE file, but anyways, here goes.
I have a synchronization program that syncs my flashdrive to my home computer and (hopefully) my flashdrive to my personal folder on the school computers. What I think would be easiest, though, would be if the program was located on the flashdrive, and would simply "autorun" when I plug it in, instead of having 2 separate instances of the sync program running at school and at home.
Would it be easier (or possible) to code for that from within the program, or with the EXE file's settings?
SerialPort Escape String - Retrieving Data From A Device Connected To A Virtual Com-port
Aug 13, 2010I am writing a small app that is retrieving data from a device connected to a virtual com-port. I connect without problems to the device using the settings 9600-8-N-1.
I need to send the command <esc>MS , the device then sends back the data to a computer. I have tried this using Hyperterminal with success. I also did this with Excel and VBA. I used the MSComm32 Active X control:
MSComm1.Output = Chr$(27) + "M" + "S" + Chr$(13)
Msgbox(MSComm1.Input)
This made the data from the device pop up in a messagebox. I am writing a winforms app in vb.net, using VS2005. I have a form, on which I have a Placed a SerialPort control, named sp. My sample code is as follows:
Private Sub Form1_Load(ByVal
sender As System.Object,
ByVal e
[CODE]...
This returns the error message "Error: expecting a command". I have done som tests in HyperTerminal, and have concluded with:
-If I dont send <esc>, I get error "Expecting a command"
-If I send wrong command (ie MD instead of MS) i get error "Bad command"
Based on this, I suspect that I don't pass the escape character correctly to my device. So I wonder how to do this?
