How to get hardware Ids of a CD/DVD drive?

Hi,
I am trying to get the Hardware Ids of installed CD/DVD drives. Is there any API (in win SDK, for native c++ app) which I can use to get the hardware ids?
Example:
IDE\CdRomhp_DVD_A__DH16ABSH______________________YHDF____
IDE\hp_DVD_A__DH16ABSH______________________YHDF____
IDE\CdRomhp_DVD_A__DH16ABSH______________________
hp_DVD_A__DH16ABSH______________________YHDF____
GenCdRom
Actually I am trying to differentiate between physical CD/DVD drive and virtual CD/DVD drive.
Thanks,
Mahesh

Take a look at the DevCon sample (this is all user space) that ships with the Windows Driver Kit. See

HT4889 Replacing System hard drive with a new one. How to get everything over to the new boot drive?

Replacing System hard drive with a new one. How to get everything over to the new boot drive? Should I use Carbon Copy or does apple have a better untility to do this?
I can't get my current system drive (OSX 10.8.3) to start on the first try. I always have to shut down and restart again to finally see the Apple logo.
Have used disc utility to repair the disc and permissions several times and that works. The next time I boot up, it works fine and I get the apple logo, but then the second time I boot up, it's back to the blank screen again and it only boots after the second try. I have tried this repair three different times now always with the same result. Works right the first try (after the repair) then from the second time on it doesn't work. I just get the white screen until I reboot a second time.
Thinking I should change drives but what's the easist and best way to move everything over to the new drive so it will boot correctly with all my data on it. This is the system drive for a Pro Tools 10HD setup. MacPro 3,1 with 16 gigs ram and OSX10.8.3 on it.
Thanks for any help!

If you have a time machine back up of your current drive you can do this
Shut down your computer, install the new drive. While the computer is off plug in the external hard drive that you have your time machine back up on. Hold Option key while the computer turnes on, let go of the option key once you get a grey screen. Shortly after you'll see a list of bootable drives, select the one that has your time machine back up on it and boot into that drive.
From there go into disk utility, format your new drive too, osx extended journaled ( I think, double check that, its been awhile since ive had to do this), hit format
Exit disk utility and then you can use time machine to copy all your exisit data to the new hhd and then your pretty much done.
There is also a program called Carbon Cloner that will do esentially the same thing however I've never uesed it.

I purchased Elements 13 for my Imac that doesn't have a DVD drive. How can I install it without buying a DVD drive? I would like to also install it on my MacBook Pro. Do I have to buy a second version.

Believe it or not, it was the FireWire drive that was the problem! I managed to successfully install Windows 7 using an external USB DVD drive!
Well I am truly staggered, I have tried this on two different MacBook Pros, with three different external USB optical drives. Don't know if you googled as I suggested but you would find hundreds of others who have found same thing. The exception is MacBook Air which works with the Apple writer, but I don't know much about this.
Were you doing any of the special workarounds with refedit etc?

Check the manufacturer website if the device is supported on Yosemite.
If not, you can get a SuperDrive from Apple which can run on any OS X version.

How to get worksheet IDs

I want to get the worksheet IDs for a workbook. I know the ID will show up in EUL5_BATCH_SHEETS and EUL5_QPP_STATS, but if a sheet has never been scheduled or "run", it will not be in those 2 tables.
I am creating a portlet to access workbooks/worksheets and have the workbook and worksheet IDs stored in a separate table. If I could query the eul or some other Disco table, maintenance would be simplified. One thought is that the info I need is stored in EUL5_DOCUMENTS.DOC_DOCUMENT, but I have not had success "decoding" that column.
Thanks in advance,
-D-

My client didn't like the Discoverer Workbook portlet (their biggest complaing was when a worksheet was opened, the list of worksheets normally seen in Viewer was missing), so I created one with a similar look and feel that creates HTML links like:
http://<server>/discoverer/viewer/?cn=<connection>&wbk=<workbookID>&wsk=<worksheetID>The reports that are being shown are public reports, and use a public connection. I can get the workbook id from EUL5_DOCUMENTS.DOC_DEVELOPER_KEY, but I am not certain where/how to get the worksheet IDs.
In order to get something into the users hands for evaluation, I created a table that holds the IDs and other information I want. To get the worksheet IDs, I checked the worksheet properties.
But, now I have a table to maintain. Ideally, I would like to drive the link information from the Disco tables, but have not had luck getting the sheet ID.

In general, since Java is designed to run on multiple operating systems and machine architectures it does not provide much access to the underlying hardware. As mentioned, you can access the os via methods in the java.lang.ProcessBuilder and Runtime classes.

Hard Drive Failed - How to get Blog/iWeb back to new hard drive?

How do I install Acrobat without a working dvd drive?

How do I install Adobe Acrobat X without using my CD/DVD drive on my computer? I need the software but have a dead drive.

Well, those things cost 20 bucks at your nearest electronics store... Other than that you can simply download the trial and activate it with the serial or copy the installers to a USB stick on anotehr machine and run them.

How do I install new OS when (a) DVD drive doesn't work, (b) current OS corrupt

I've got a real conundrum.
I've got a Mac Pro 2x2.8 server from 2008 running OS Leopard Server 5.8... I just bought the Snow Leopard Server software on CD and was going to install when two things happened. Firstly, i discovered my CD drive didn't work... and my Super Drive didn't show up either... Secondly, the current operating system has become severely corrupted, which means I can't even load up the system.
I've tried pressing C, D, Option, Shift, Command S and Command V during startup, but not getting anywhere.
And I can't install any new software because I can't use my DVD drive - internal or external.
W-T-F-Do I do?
Is there any way to transfer the Snow Leopard CD contents onto a hard drive and load via USB / Firewire?
Bright ideas and inspired suggestions much appreciated.
Jay

For Leopard or Snow Leopard you need an installer DVD.
1. You can purchase replacements for the original discs from Apple:
Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.
To contact product and tech support: Apple - Support - Contact Apple Support.
2. Buy a new Snow Leopard DVD.
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store.

How can i download elements 11 with no dvd drive

recently i purchased elements 11 and downloaded it. however that computer was stolen and the new computer does not have a dvd drive, how can i now download elements 11?

If you have got a valid serial number for PSE11 then you can download a trial version using the method given on this page:
<http://prodesigntools.com/photoshop-elements-11-direct-download-links-pse-premiere-pre.htm l>
The download is direct from Adobe sites but you need to follow the instructions carefully otherwise t won't work. READ THE PAGE BEFORE DOING ANYTHING.
Ideally, you should buy an external USB DVD drive because you will always need a DVd drive as all software packages comes in DVDs.
Good luck.

How to get hardware's attention as soon as it gets plugged in?

I have this joystick with a cthulhu board, in case anyone has one and could use the details, and it seems to disconnect right after I plug it in. According to the person who builds the PCBs it appears the cthulhu is trying to go into PS3 mode since nothing is prompting it.
$ dmesg | tail -4
usb 4-4: new full speed USB device using ohci_hcd and address 5
input: Toodles 2008 Cthulhu+ PC/PS3 Controller as /devices/pci0000:00/0000:00:04.0/usb4/4-4/4-4:1.0/input/input12

usb 4-4: USB disconnect, address 5
I have tried using this script:
#!/bin/bash
# Polls Toodles PC/PS3 Cthulhu controller, preventing it from entering XBox 360
# mode. Run this script as root, then plug in the controller.
DEV_DIR=/dev/input/by-id
DEV_NAME=usb-Toodles_2008_Cthulhu+_PC_PS3_Controller-joystick
echo "Please connect PC/PS3 Cthulhu now."
# Loop indefinitely until Cthulhu controller is detected
until [ -a $DEV_DIR/$DEV_NAME ]; do
DO_NOTHING=""
done
echo " - PC/PS3 Cthulhu detected. Ensuring connection..."
# Have Cthulhu scream into the void for a couple of seconds to ensure connection
cat $DEV_DIR/$DEV_NAME > /dev/null & CAT=$!
sleep 2
kill $CAT
echo " - PC/PS3 Cthulhu connected!"
And I tried editing /etc/udev/rules.d/10-local.rules so it contains the following:
SYSFS{idVendor}=="14d8", NAME="input/%k", RUN+="/bin/touch /dev/input/%k"
But those approaches didn't seem to work. It used to work and one day it just wouldn't, it was probably after an update and, since I don't play every day with it, I'm unsure as to what caused it.
Any help will be appreciated
EDIT: The stick is working fine, I have tested it on Windows.

Hi
What you are looking for is an ultra fast indexing mechanism . Actually indexing depends a lot on how good the DB is tuned to churn out and process the documents that are there in it . If you want to have this sort of a feature where in you want the contents to go to Released status as soon as you checkin contents then you will have to set up the DB to do the processing fast enough and give out the results. If it is Full text based indexer for the CS then whole lot of data has to be processed by DB .
One hint to get this done is to use Oracle Query Optimizer component with which you can create hints for the db to do the query processing fast . Also creating indexes (additional to the existing) for the columns in docmeta , revisions table would also help a long way .
