I don't know about different lasers but definiely different power levels which could change the laser's behaviour.

Hiii
For testing a NMS (network management system) , we need to create virtual networks of different types having different devices such as WinXp machines, printers, scanners etc.
There are softwares available to do this, but we want to develop our own.
Any hints on what needs to be done ?? 
i mean how can i create virtual systems by writing some code ?? which dlls , which APIs etc ??
If you know it , Please help !!!

Hi All,
Hoping someone with some RFID experience can help me gauge an understanding of it.
Do the readers get the Co-Ords of the tag, or is the location based solely on which reader has picked up the tags signal?
I know some companies say they use it for stock control, so just wanted to get an understanding of how that worked.
Regards
Tony

Most RFID tags have no locator capabilities. The location is determined by knowing where the reader is, not the tag. Since the range of an RFID tag transmitter is very short (usually within 10 feet), the tags location is the location of the reader antenna.
The tag passes through a field generated by the reader. This generates a small current in the tag which powers up and transmits its ID. The reader picks up that signal and reads the tag ID.
That's the basics of how it works anyway.

I like the "powers up" part.
Kinda makes me think of a huge robot, whose eyes begin to glow as it slowly gets on its feet....
Or a plant after an accident of some kind.
You know, with beeping, lights flashing about, strange smells of partly burned electronics...
Cheers,

Hello all,
As soon as I was able to get it into my computer I bought a Matrox card with dual head in order to increase the productivity.
Now I have a new computer and also I got a new matrox card with dual head. That computer came with an ATI card inside that now is not being used.
One coworker has a Pentium 4 with the 915G chipset that has an integrated graphics card. I was thinking on adding that other graphics card there in order to be able to use them both.
Do you think that this is possible? which things should I consider?
PS: I would like to be able to have two separate monitors working with the same computer, like the effect I get with the Matrox Millenium P650 that I have in my computer.
As always thank you in advance.

yes it is possible but you can view same thing on both monitor, am i right?

No, I don't want to see the same on the two monitors...
I would like to extend the windows desktop to the second monitor. In this way, you can have, for example, the MSDN in one monitor and the VC++ in the other one.
This is intended to improve the productivity avoiding to minimize and maximize continuously...
Thank you.

This is VERY dependant on motherboard, but many (I won't say most, because although I have eval'd many, I can't even touch a decent percentage of 'all') motherboards will disable integrated graphics if you put in a graphics card (or worse, force you to disable it before it recognized the graphics card as a graphics card -- you can spend half a day before you realize that the motherboard if fighting you to not recognize the card).
The other part is slot type. You can have any combination of PCIe + PCI just as you could have AGP+PCI, and now you can have dual PCIe in parallel integrated (SLI or CrossFire) or parallel independant (for more displays). Windows handles this fine, **IF** the hardware supports it. I don't mix brands because drivers tend to fight each other, but I know several people who have got multi-brand working in multi-card/multi-monitor integration. But you will make life easier with same-brand and same driver situations.

OK, after reading several notes from different people here, I've decided to buy a new card with 2 heads.
Thank you.

that is the easiest way to do it. Not always the cheapest if you have left over equipment, but if you count your hours into the equation, it looks better on paper to just get a 2 head graphics card.

Yes, it's a pity to throw hardware to the box of those old things that never are used again, but well, it happens so as you say about equations... it's better to spend time in other things...
And that graphics card is very cheap so this is not a big deal, it was more related to the fact that I wanted to make it work...

then again you never know what'll come out of that box to be used again someday. Last weekend the cheap mobo with onboard gfx I was using for my spare box died. I had an available replacement, but it didn't have onboard gfx. Rather than spend $30 on a new cheap PCIe card, I installed a PCI matrox card from a 1997 vintage P1. I'd originally intended to ebay the mobo I used but probably wouldn't get more than $80 for it if that, a good 939 mobo with onboard gfx would be ~$70 so the antique card was the cheapest option. For normal use that box just crunches einstien@home so it doesn't need a highend gfx card, and if my main box goes down I can borrow the card in it until I rebuild.

Yes, that's the main idea on having that box in the darkest part of our office, sometimes it's handy, but rarely and it becomes easily forgotten...

I dont think you can use the integrated and discrete card at the same time.
if you really wanted to Extend you desktop to second display why dont you just use intergrated card and attach a second display via some ADD card.

Hi
I Wanna know that is there a standard set of BIOS Interrupts for each and every Video card or I have to do Programmed I/O to access video card.
In case there are set of interrupts please let me know or if i hav to do I/O then let me direct to some link where I can found the port addresses with specification(i mean standard set).
hope somebody answers me soon.
bye

It's about time I upgraded my old DLink DI-714P+ to something newer. If anyone has had any recent experienced with buying a gigabit (yes, I'm looking for something that is gigabit) router (yes, specifically a router. not a switch or a hub) with _more than 4 ports_, please post what you recommend. I did a quick search, but nothing stood out. I didn't dig in much, due to lack of time.
Hmm, if it makes any difference, this is for a home network, not office or antyhing like that. But we _do_ have quite a few machines at home, hence the need for at least 5 ports.
Thanks in advance,
Anton A.

Could you please post your old DLink specs?
You might be looking for a L3-Switch integrated in a router, not a router per se.
Since your especially asked for a multi-port routers: The ones I know are modular frames (port extensions cost extra) and start at 10000 monetary units (Cisco Catalyst, 3Com routers), used.
You might just be wanting to route out of a local network (one external connection, 4+ internal connections, which could easily be done with a L3-Switch).
But without more details, I am afraid that is all I can provide you with.
€dit:
Mangaged Layer 3 12-port 10/100/1000-Ethernet Switch:
Netgear GSM7312 (ca. 1000 USD)
Unmanaged Desktop 8-Port 10/100/1000-Ethernet Switch:
Netgear GS608 (ca. 70 USD)
You could combine the last one with a single-port Gigabit-Router and would receive a 7-Port-Gigabit Router with Gigabit Capability for around 150 - 200 USD.
If you need ADSL, I suggest using a single-port GBit-Router with integrated ADSL+-Modem connected to the same switch.
Cheers,
Sebastian

Hi,
I need to measure the temperature of CPU.
I understand that I have to use WMI for this.
Using wbemtest.ext when I connect to the namespace root\WMI and in the query, type 'select * from MSAcpi_ThermalZoneTemperature' , I get 'null' value for 'current temperature'.
Does that mean that I will not be able to measure the CPU temperature?
If this is not the method, can anyone please help me with measuting CPU temp?
Any info in this regard will be very useful.
Please also direct me , if this is not the correct section (hardware) to post this message. I will post it in a correct section.
Thanks,
Manasi

Hello Manasi and welcome to CodeProject!
For you question, I only have to say that some motherboards do not support measuring CPU temperature, so I suggest that you go to the manufacturer website (or the manual if you have it) and check that first.
Other than that, I don't think I can help much as I've never had the need to check the CPU temperature programatically.
P.S. change your display name to something more descriptive than a blank space

Thank you for your reply..will check the manual..and have changed the display name as well

1) The onboard CPU temperature monitoring circuitry is notroiously unreliable and inaccurate.
2) Just find and download a problem like Motherboard Monitor. It will also report system fan speeds and stuff like that.
