Yes,
you can always go for a matrox, they offer QUAD display with one card without any problem.
Also they offer "triple head to go" that's a little box that will allow even your laptop to work in that way.
I've always had a matrox installed, they offer reliable solutions that work without any problem and have lots of tools that will help you to be more productive like being able to configure how you want to maximize, how the mouse will work...
PS: they are slightly more expensive than the cheap nvidia and ati graphics cards, but they are worht it.
Hope this helps.

I've just purchased a geek toy. USB Missile Launcher and the software for it keeps locking up. I've been to the manufacture website for updated software and it does the same thing.
My question is how would I go about writing my own software for this device? I have a dll that I can NOT register with XP and have tryed to add a reference to my new application but I get this error, "Reference to c:\my.dll could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component."
Any advice on where to start would be great!
I'm listening but I only speak GEEK.

hello,
I'm capturing input from a USB webcam, do some filtering on the video and would need to output it to another, this time virtual, webcam device that I somehow need to add to the system (WinXP SP2). Even a .NET solution is okay with me (though I doubt there is some).
1) would I need a custom device driver to do that?
2) if not, which way should I go?
thanks

I've got a Windows 2000 machine with an ethernet card in it. Apparently the card was mfg'd after Windows 2000 came out as the OS has no driver for it (per Device Manager). Is there anyway I could get a generic driver just to get connectivity, and then get online to search for a specific driver?
Thanks,
DC

Identify the chip used and go to the manufacturer's website - e.g. Realtek, Marvell, Intel etc..
Often the driver works for any board with the chip.

Good advice from the previous poster.
Just to let you know, I have an NT 3.51 driver on a network card on my 2K box.
Drivers are very backwards compatible.

Thanks, that's good to know. The owner of said machine has a driver CD that shipped with his installation of Windows Me. Hopefully that'll get him going (enough to get access to an updated driver).

Windows ME used a 'kind of' WDM (Windows Driver Model). It also used a lot of virtual device drivers (VxDs) and is still dos based, as was Windows 95 so there is a fair chance the Me driver wont work on 2K.
As the other poster stated, lok for the chip set on the card, and get an NT driver for that chip set, it doeasnt matter if it is an NT 3.51, NT 4 or NT 5 (Windows 2K) drver, they will all work.
An XP (NT 5.1) driver wont though, it is too recemt and will use the NDIS 5.1 model which 2K hasnt got.
As you might have noticed the NDIS version number is the same as the OS version number.

I installed a slave hard drive on my work system at home. It was working fine. Then all of a sudden the system started crawling. I ran a virus scan (latest Norton), and nothing was found.
I then tried to access my 2nd drive and it said it wasn't formatted. I yanked it out of that machine, and put it in a USB case. Plugged it in and the same error came up. I tried it on another machine, same error.
I have never seen a hard drive unformat itself. There were a few things on there, but nothing that's mission critical. But, I would like to verify this before reformatting it.
I tried fixing the MBR, but it didn't fix the problem.
Any ideas how I can restore the drive, or see the files on it?

It's not really unformatted. It's more probable that the partition table has been corrupted. You can probably find out more with these[^].

Thanks for the tips. I brought the disk into work, and they used some recovery software and were able to recover the items I needed.
Thanks!!!

Have you tried using frhed to look at the raw contents of the disk? Very low level I know, you'll probably need to understand a bit about the file system itself but at least it'll help you identify whether it's worth delving deeper.
I have no idea what I just said but my intentions were sincere.

Hi
Can any help to know that :
1. Is Sound Blaster present on every sound card.
2. Is it like this if I wrote routines to access Sound Blaster it can play on every system.

No. It's a widely used card, but not everybody uses one. Many people have built-on sound cards on their motherboard, common known as AC97.

Sound Blaster[^] is the trademark name of sound cards made by Creative[^]. You should use the hardware-independent sound routines provided by your OS to write code that works on any sound card. If you want to write multi-platform code, see SDL[^].

Hi All,
We are starting a project (.NET/C# DB: SQL Server) and one of the main requirements is performance and reliability (the system is a "mission-critical" one).
Could you please indicate articles/books/sites that could help us on:
- Defining the minimum hardware requirements (how many redundant servers should be considered, RAIDs, etc.) based on the expected number of user/requests,ammount of data etc.
- Technologies that could be used in order to support the desired reliability ( distributed services, load balance for example)
Thanks a lot,
Sergio

Hi,
I have implemented in the code for wmi. It works just fine for cimv2 workspace and Win32_OperatingSystem class.
It is not working for any other class (i need Win32_CDROMDrive) in cimv2 namespace. Not even working for root/wmi namespace.
Is there anything else that I need to do?
Please help.
Thanks ,
Manasi

The connection is completely seperate from the class your requesting. Does the connection work? Then you execute a WMI Query on that connection. If the connection works on one class, it'll work for every class, so long as the client machine supports that class AND has an instance of it to return.
We'd have to see the code your using to request this class to make any more recommendations.

Thanks for your reply .My connection works. Please find a part of my code:
(uReturn value is always zero for any class other than Win32_OperatingSystem,for which it is 1)
IWbemServices *pSvc = NULL;
hres = pLoc->ConnectServer(
_bstr_t(L"ROOT\\cimv2"),NULL,NULL,0,
NULL,0,0,
&pSvc);
if (FAILED(hres))
{
AfxMessageBox(_T("Could not connect"));
pLoc->Release();
CoUninitialize();
return 1;
}
AfxMessageBox(_T("Connected to ROOT\\wmi WMI namespace"));
hres = CoSetProxyBlanket(
pSvc,
RPC_C_AUTHN_WINNT,
RPC_C_AUTHZ_NONE,
NULL,
RPC_C_AUTHN_LEVEL_CALL,
RPC_C_IMP_LEVEL_IMPERSONATE,
NULL,
EOAC_NONE
);
if (FAILED(hres))
{
AfxMessageBox(_T("Could not set proxy blanket"));
pSvc->Release();
pLoc->Release();
CoUninitialize();
return 1; }
IEnumWbemClassObject* pEnumerator = NULL;
hres = pSvc->ExecQuery(
bstr_t("WQL"),
bstr_t("SELECT * FROM Win32_CDROMDrive"),
WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,
NULL,
&pEnumerator);
if (SUCCEEDED(hres)){
IWbemClassObject *pclsObj = NULL;
ULONG uReturn = 0;
while (pEnumerator)
{
HRESULT hr = pEnumerator->Next(WBEM_INFINITE, 1,
&pclsObj, &uReturn);
if (FAILED(hr)){
AfxMessageBox("Failed");
}
if(0 == uReturn)
{
break;
}
VARIANT vtProp;
hr = pclsObj->Get(L"Name", 0, &vtProp, 0, 0);
CString OS = vtProp.bstrVal;
AfxMessageBox(OS);
VariantClear(&vtProp);
}
if(pclsObj) pclsObj->Release();
My connection is made..in tha last step, after querying, uReturn value is zero, and loop breaks.
Where am i going wrong? I am a beginner in this. Please excuse if there is some silly mistake i did.

I have a problem with my fairly new Asus mainboard, it's a P5WD2-E Premium. If I set the Bios to enable the usb ports to run at 480MBs then try to boot with my USB keyboard and mouse attched, the computer locks up on the initial windows boot screen. My step dad had a similar problem with his Asus mainboard. Is this a common problem and/or is there a fix to it. Please help if you can, it's really frustrating.
Posted by The ANZAC
p.s. My Bios is up to date, the problem has occurred before and after the update. I am using a microsoft wireless keyboard and a no-name optical mouse.

Sir/Madam
I am Final Year Engineering student. I want to get information about connection of computers at different cites.
Actually if I want to computerize a department of any company which have its offices at several cities then what steps I should follow.
Means how I can connect that no of computers in appropriate manner to get desired output.
I want to make it just like railway reservation system through in which if I enter data at same time then database must be able to prioritize data in sequence to enter in database.
Which database & platform or language I should use to code this kind of project.
What hardware i need to do so.....
Thank You
