Re: how to know that an internet connection is alive at some instant?

If I remember, there's a way to check if the internet connection is active through WMI. The failing of this method I remember was that you don't know if there's an internet connection but that the LAN connection is active. It is assumed that if the LAN is active there is an internet connection.

Assumed by who? A LAN connection does not mean that LAN has access to the internet!

I know that, what I meant is the solution's draw back was that it assumes that if there is an active LAN connection then there is Internet connectivity.

Then iterate over each of the databases performing the same query.

To identify all user defined tables on a particular instance, you would use select name from master.sys.databases where owner_sid != 0x01

And? How am I supposed to know what databases you have? I did state that this was per database instance so, if you think you are missing some, you need to check to see that you are hitting the right instance. For instance, you may find that one instance is running as (local) and the other as (local)\SQLExpress.

Hello guys,
I am struggling for 3 days now with the problem of reading and writing form/to an usb port. For this I tried to use LibUsbDotNet. The library has a very nice and at first I though useful documentation. My problem is that I cannot reference the UsbDevice object that I want to use.
I tried to iterate through the UsbDeviceList but have no success because the List is empty (I cannot understand why) . I tried with different sticks and card reader device and the result is the same the DeviceList is empty obviosly I doing something wrong but I cannot figure what .

<br />
UsbDeviceList usbDeviceList = new UsbDeviceList();<br />
IEnumerator<usbdevice> enumerator = usbDeviceList.GetEnumerator();<br />
            while (enumerator.MoveNext())<br />
            {<br />
                usbDevice = enumerator.Current;<br />
                if (usbDevice.Info.IdVendor == infoDevice.IdVendor)<br />
                    break;<br />
            }<br />
</usbdevice>

LibUsbDotNew Library[^]

Hope some of you worked with this library and cam help me with some useful tips.

Thanks

Try this: http://www.icsharpcode.net/OpenSource/SharpUSBLib/default.aspx[^] but it will need this installed: http://libusb-win32.sourceforge.net/[^]

I've tried it in 2 previous projects and it works like a charm.

I haven't tried LibUsbDotNet so I can't help you with that one, sorry.

First I did not wnat to use that library but seems that I have no other sollution.

The problem with that library is that I didn't find a decent documentation and that it isn't maintained anymore.
Also you need to install the LibUSBwin 32 first ...

If you have some documentation or if you know a link please send a reply
Thanks.

Sadly, no. The projects were accomplished by looking at the samples that came with the download, that gave me an idea of what to do. Their object model isn't convoluted at all from what I remember.
