sanjana,

Your problem will be solved by the computer, so why try bother with
programming, unless making your own computer?

C# isn't meant to solve your kind of problem, its for software
devolopment!

There are many reasons why you would want to detect this in a program, maybe
you want to wait until a USB is inserted into the computer and then retrieve
all the images of the USB, there are a thousand and one reasons why.

C# can definitely be used to solve this kind of problem.

hi i tried th following to detect if anything is connected at the usb
port..dint work

class usbdetect
{
public static void Main()
{
usbdetect we = new usbdetect();
ManagementEventWatcher w= null;
WqlEventQuery q;
ManagementOperationObserver observer = new
ManagementOperationObserver();
// Bind to local machine
ManagementScope scope = new
ManagementScope("root\\CIMV2")*;
scope.Options.EnablePrivileges = true; //sets
required privilege
try
{
q = new WqlEventQuery();
q.EventClassName =
"__InstanceOperationEvent";
q.WithinInterval = new TimeSpan(0,0,3);

q.Condition = @"TargetInstance ISA
'Win32_USBController'";
Console.WriteLine(q.QueryStrin*g);
w = new ManagementEventWatcher(scope,
q);
w.EventArrived += new
EventArrivedEventHandler(we.Us*bEventArrived);
w.Start();
Console.ReadLine(); // block main
thread for test purposes
}
catch(Exception e)
{
Console.WriteLine(e.Message);
}
finally
{
w.Stop();
}
}
public void UsbEventArrived(object sender,
EventArrivedEventArgs e)
{
//Get the Event object and display it
foreach(PropertyData pd in
e.NewEvent.Properties)
{
ManagementBaseObject mbo = null;
if(( mbo = pd.Value as
ManagementBaseObject) != null)
{
foreach(PropertyData prop in
mbo.Properties)
Console.WriteLine("{0}
- {1}", prop.Name, prop.Value);
}
}
}
}
but its not working.......? wats the error..it does not detect if
a device is inserted at the usb port..
