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!

Hi
Two weeks ago I had this problem.
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!!!!
hope I hade solved ur problem .

new pc(to which my device ever not be attached),a system reboot message accur,but in fact i do not
need to reboot my system and my device still work well.
The title of the message is :"System Settings Change"
The message says:"Windows2000 has finishedinstalling new device,You must restart your computer before the new settimgs will take effect,do you want to restart your computer now?"
So my question is:

Hi Dear,
My Key board is UK based but it works like a USA based key baord.
How can I change it back to UK based Key board
as you know there are some key characters are different among them.
thanks

Alt+Shift (left shift key)
|
|
|
|

The keyboard layout - which characters appear when a given key is pressed - is under the control of the operating system, not the keyboard itself. In Windows XP and Server 2003, go to Control Panel, Regional and Language Options, Languages tab, click Details, then click Add. Select 'English - United Kingdom' from the Input Language drop-down, then 'United Kingdom' or 'United Kingdom Extended' from the Keyboard Layout/IME drop-down. Click OK.
You probably won't want the US keyboard layout even available for selection, so select 'US' under 'English - United States' and click Remove.
United Kingdom Extended is a new keyboard layout in Windows XP SP2 and Windows Server 2003 SP1. It allows a few more accented characters to be typed, compared to the standard UK layout. The standard layout only allows áÁéÉíÍóÓúÚ to be typed directly (press AltGr and the base character, plus Shift to get uppercase). The extended layout adds ẃẂýÝçÇ by typing with AltGr.
It converts the backquote key ` into a so-called dead key, which combines the grave accent with the key that follows (if available), e.g. ` followed by a = à. Pressing a key that doesn't combine produces the backquote followed by the key you pressed, so ` followed by c = `c. To get a backquote alone, press ` then the spacebar.
Four other key combinations produce dead keys which work in the same way: AltGr+2 combines an umlaut (two dots) with the next character, e.g. AltGr+2, a = ä. AltGr+6 combines a circumflex, e.g. AltGr+6, a = â. AltGr+# combines a tilde, e.g. AltGr+#, n = ñ. Finally AltGr+' combines an acute accent, e.g. AltGr+', a = á.

What do you guys think?
A friend of mine is about to buy a new computer.. But he doesn't know wich to choose:
AMD X2 3800+. If the SKT is 939, DDRII 480MHz, else DDR, offcourse
So you guys think he should choose SKT939 or AM2? Why?
best regards
hint_54
|
|

|
|
The performance gain between the two sockets is extremely close to zero since AMD's architecture is much less memory limited than Intel's. AM2 only adds DDR2 support, and the only reason it came out when it did is that the pricegap between DDR1 and DDR2 has shrank to almost zero, and in the future will swing in favor of DDR2 as DDR1 becomes an obsolesent technology and doesn't benefit from factory improvements. IF your friend doesn't plan on upgrading anything on the mobo, and can find a 939 system for significantly less buy it. IF he might need to add memory or a better CPU in the future or if the prices are almost identical, get the more futureproof AM2 system.
