this is a known windows 2000 bug. to fix it you need to put a filter driver over usbstor.sys that mods the response to IRP_MJ_QUERY_CAPABILITIES.

Are you implying you want to do it via the Serial Port? See the SerialPort class in .net 2.0. After that, you'd have to do some API searching...

Your probably infected with a virus or a Trojan. Scan your machine and you might come up with some interesting results!

Sounds as if something got seriously corrupted in the Registry. Never happened to me before, but then again,I never tried 'cmd' either! I always use 'command.com' cmd is a reference to 'c:\windows\System\command.com'on my system.
If you type in the above system path, and you get the DOS Screen, there is nothing wrong with the command processor, but you should investigate.
Start with opening the Registry and search for 'cmd' , follow from there.
N.B.
The fact that you want to break into character mode (DOS Screen) makes me think that you're well used to .Bat and .Ini files
Well, those AutoExec.Bat and Sys.Ini files have gone. That information is now stored in the System Registry. Please read books about the registry, and familiarise yourself with the subject before you make any changes!

I think that you've got a virus.
Do you have any anti virus?
If you have update your anti virus,but I think you have to reinstall your windows

Can I read data at rate of 400MBps or more in Scazzi Harddisk?
|
|
|
|
|
You'll have to clarify this a bit. Are you looking to TEST the data rate or are you trying to see what the drive says about itself??
And it's SCSI (pronounced SCUZI)...

No. Even 15000rpm SCSI disks cannot sustain this transfer rate. The quoted transfer rates on Parallel IDE (133MBps), Serial ATA (1.2Gbps, 2.4Gbps for SATA-II), Ultra Wide SCSI 320 (320MBps) and Serial Attached SCSI (SAS, 3.0Gbps) are simply the theoretical speeds available on the transfer bus. If reading from or writing to the drive's on-board cache, this transfer rate can be achieved, but only (of course) up to the capacity of the cache, which is typically in the 8MB to 16MB range.
|
|
|
|
|
Once you've flushed/saturated the cache, a 7200 rpm drive will run at ~66Mbps.

I have an application where 4 audio files are played simultaneously in two channels of two conventional stereo cards. I have to migrate this to playing using a 5.1 system. There are limitations to existing WAVEFORMAT which does not identify multi channel device.
Can anyone help me with the procedure how to pack the audio packets (for 4 files) and assign to the multi channel sound card?
Any help is highly appreciated.
Thanks in advance.

Hi,
setup: Router, connected to the internet, and a xbox 360 console several rooms away. They are not connected with a ethernet cable.
Now I want to plug an ethernet cable into the xbox which connects to a wlan adapter, and I also want to plug an ethernet cable into the router which connects to another wlan adapter. These two adapters have to connect to each other so that it's quasi a wlan bridge between these two replacing the physical ethernet cable.
Is this possible? What kind of wlan adapters do I have to buy? How do I setup them? I want the stuff to work just like a normal LAN.
Regards,
Stefan

hi,can anyone please tell me how the switching from user mode to kernel mode in windows happens?
i mean what ensures that a user mode application does not make a cpu-mode switch and then jump into the kernel
or access hw directly?a short description of how and where the switching procedure happens would help a lot.
thanks

Thread priority and time slicing take care of it.
When an app calls CreateFile(), the IO manager calls into the driver that owns this symbolic link, hitting its dispatch handler with an IRP_MJ_CREATE.
Same for WriteFIle() IRP_MJ_WRITE etc.
And, if the app has opened the file for sync IO, that calling thread in the app will be blocked untill the driver completes that IRP (IO Request Packet).
For data coming in, the driver will get an interupt, and this will absoloutely throw anything at a lower priority off the CPU and the system will call the drivers Interrupt handling routine.
You should look at stuff online about the NT scheduler, kernel, interupts, and so on (XP is still windows NT by the way)

Ah, and security. Memory in the virtual address space an app sits in is secured. So the app can only get to the bottom 2 gig on a 32 bit PC. The kernel has the top 2 gig.

I can only assume that you want to try and switch to Kernal Mode in the midst of your User Program. This is something that generally should not be needed in any user program. Windows puts up several layers of defence to stop you from doing so!, and for good reasons! (Remember Dos??)Read your Windows Documentation, find a way around whatever you want to achieve! In the long run, it is the better way, it is likely to continue on running with the next version of windows. If your program relies on anything in the kernal, it probably won't survive the next windows upgrade! (Don't be Stupid, I've Been there);)

The Switching between User and Kernal mode, happens in the background, and is an issue that User Mode programmers(as opposed to System Mose Programmers, which are mostly those working for Microsoft, writing the Next version of Windows), should have NO Concern about! There are ways of putting the system in Kernal Mode, but, I'm Not going to tell you, because you sound like someone who has not a notion about how windows works. believe me, I am saving yourself, and the friends to whom you propose to pass your software on, from a lot of hassle which would ensue if you went that way!
Go the Windows Way, and use the WIN32 Api. Excepting special programs (e.g. Specialist Debuggers) Kernal Mode switching IS Not Needed!!!

hey man some possible solutions could be:
1 Check out the connections inside the cabinet their could be an possible problem their ,provided u now thoroughly all the internal conections.
2 Ia'm not sure it could be an O.S problem ,so try reinstalling ur O.S aggain coz' i don't think their is any pboblem with ur CDROM
3 Since u haven't mentioned ur motherboard details so i can't say that a change in CDROM details would cost u those problems!
4 If notin works out then call an technician!!!!
