Dear Mr. Luc Pattyn:
Thank you for your comments to my problem.
My concern is that the KMDF device driver causes troubles on the USB device because of frequent interrupts. (Some USB devices do not want frequent interrupts.)
By the way, I polled the same question at the Microsoft Connect site
and received some responses from Microsoft.
If you are interrested in this issue, please refer to the FEEDBACK REPORT (BUG ID 418229).
I will control the Interrupt IN polling in the user mode application program intead of using the KMDF continous reader. I will refer to your article.
Thanks.
Yama Fuji.

hi all,
In our company we are using 1mbps airtel broadband connection we are connecting the Lan connection connects via system ethernet card as IP address for other machines we chose as Default gateway thats is working fine ...we brought the BSNL DSL conncetion for 2 mbps in this Airtel also wants to work and BSNL also work.. how it can possible

Why? Typical PC speakers use less power than the fans inside the box. What would be the point? For some real savings, I'd like a desk lamp that goes out when I leave the room...

Anyone know what would be involved in hooking a USB cable from my laptop to some other computer, and using the laptop to serve as a keyboard for that other computer?
I know USB cables have an A & B side, so I'd have to do some connection jiggering, but I think it would be interesting project.

That will be difficult.
For one, USB has a single master (normally the one and only PC) polling all the slave peripherals. In your set-up there would be two masters. And USB connectors enforce this single-master concept by being polarized, you can't physically connect two masters using commercially available cables.
However modifying a cable is only a small part of a possible solution. The protocol itself will fail with multiple masters. You basically have to turn your laptop-acting-as-keyboard into a USB slave device,
disable its plug-and-play logic, then make it send keyboard packets rather than receive them.
If and when you succeed, please do write a CodeProject article on the subject.
PS: I expect you also want to use the laptop's display as a monitor? over USB??

You can't directly. There are programs (synergy[^] and multiplicity[^]) that will let you send keyboard/mouse input from one PC to a second over ethernet. In this setup the master's keyboard and mouse will be able to move the cursor across both systems (function is logically similar to a 2nd monitor), while the slave will only be able to control itself. These only work once the OS has booted and is running the app on both ends.

Your best bet would be to get a development kit for a USB microcontroller (such kits are available for $100 or so) and then write code on the microcontroller to mimic a keyboard that is sending out the data you're after. The microcontroller could easily be programmed to send out keystrokes in response to any particular type of stimulus. If you need to have it do so in response to data from the laptop, you could use a serial port. If the evaluation board has an RS232-to-TTL convertor (many do) you might not even have to solder anything.

What s the cost of 1 GB RAM ? (Indian Rupees)
|
|
|
|
|
12.99 USD on Amazon.com[^] = 592.56 INR
That price is a fixed price to which all members of the UN agreed in the DDR2-RAM-Price-treaty of 2005. If anybody charges you more than 597.24 rupees for 1 GB of RAM, you should immediately call the police, since they try to trick you.

Hello sir ,
What s the cost of 1 GB DDR RAM ?
|
|
|
|
|
$45.39 on amazon.[^] = 2070.54 idiotic retards.
The price is controlled by the same treaty as DDR2 pricing.

I have my wifi network card set up in ap mode and my network card connected to the internet in shared mode. I want to allow a device to connect to my PC via the wifi and access to internet, but it doesn't work. The device can connect to the PC, but not the internet. Any ideas what I might be doing wrong?

Well, if you haven't anything else set up, the two network connection are isolated. Each interface sees the PC, but not the other interface.
Enabling ICS (Internet Connection Sharing) might solve the problem. If that does not work, try installing routing software or setting up a network bridge.
See this website[^] for mor information.
Cheers,
Sebastian

Thanks for the answer.
I tried the sharing thing, but unfortunately it doesn't work. If I set up the network bridge I lose the internet connection to my PC

|
|
I also tried installing nat32, but no good. I guess I'll just have to admit defeat and buy a wifi router
|
|
|
|

Well, that's the cleanest approach. And it might save some energy.
You can even get a simple "NAS" with those routers. (Usually not really a NAS, but shared access to some flash memory, builtin or plugged in via USB).
Cheers,
Sebastian

I've used the ICS approach in the past, but the performance was terrible. It's much cleaner and more reliable to use a WiFi access point and have all your clients connect directly to it.

It's because your harddrive is broken.
And it seems that your keyboard is broken too.

Its because i've enabled System restore option for C Drive .Now its fine .

I've just put a system live today and I'm having issues connecting to SQL 2005 from w2k.
SQL 2005 (64 bit with latest service pack) is on windows 2008, 64 bit server.
Everything was tested before going live and worked fine. The only difference now is that there is a firewall between the systems.
From the w2k box, I cannot connect to SQL 2005 via SSMS. Interestingly, there is also a problem actually using the website from the same computer. When submitting a form, the system just hangs. This happens both on IE and firefox, so I'm guessing its not a browser issue.
Error message from SSMS is tcp error 0, the specified network is no longer available. SQL error : 64.
Google has not thrown up any ideas so far (and I've been looking for about 6 hours now)
I can access the website from XP laptop and also from W2k3 server. I have tried installing SQL 2005 on laptop, but I had 2008 trial on it some months ago and it seems some remnants of that are causing the install to fail, but thats another story....
Also of note, I CAN connect to the SQL 2005 box from w2k using Sql 2000 query analyser OK and if I change the connection string on dev system on w2k box to the live SQL server, it connects fine.
Has anyone experienced this before? Any ideas on workarounds / fixes
