Why can't CaptureDeviceManager.getDeviceList() get capture device?

My laptop can capture sound from microphone. But CaptureDeviceManager.getDeviceList(new AudioFormat(...)) can't get any device from my system.

Try deleting it from MAX and then adding it again.
Or resetting your MAX configuration and then rebooting.
Lastly, dry reinstalling MAX.
Since so many pieces of software depend on MAX, you'll probably have to reinstall other NI software if you go this route.

Why can't BT ever get an order right?

Why can’t BT ever get an order right?
I placed an order for a telephone and broadband package last week on the 15th with an install date of Friday 25/10/13. I paid my line rental up front and got an email with the order details stating I should get another confirmation email within 5 days.
6 days later surprise, surprise no email. So I ring the number to call on the email and get through to Robo-BT the talking twit. It asks me to explain my problem and will then put me through to the right department which of course it doesn’t because it doesn’t understand human. 20 minutes later with only two disconnects I finally get through to a human and begin the BT Shunt between departments; three in total only taking 25 more minutes. I then get told the order is stuck somewhere in one of BT’s systems and needs to be cancelled and restarted because unlike any other company on the planet BT can’t just fix something or move the order along or manually progress it, they have to pick the worst possible solution to a problem! So they cancel the order and tell me I will be refunded the month I have already been paid (Which I haven’t as yet!)
After going through all the order details again (which were in front of the advisor on the old order!) and repeatedly telling her no when she kept trying to hard sell extras I didn’t want, we finally got to the appointment stage and I was then told… “Good news! We can have an engineer out on the 22nd of November!” I replied: “WHAT?!?!?! That’s over a month away and my first appointment was for this Friday? Why can’t you get an appointment before then?” she said “The engineers must be busy!” She said you can still use your BT ID to log on to BT Wi-Fi to get internet access in the meantime. So I said yeah whatever but I couldn’t make the 22 so said to make it for the 28th of November.
Once the email came through confirming the order again I noticed the BT Internet email hadn’t been setup and therefore I can’t even get in to BT Wi-Fi to see if it works! So to sum up:
I’ve paid out £141.00 for a service BT has cancelled and not refunded!
I have to wait 6 and a half weeks before I can get a phone line!!! Surely that’s in breach of the SLA’s and I should be entitled to some form of compensation or the appointment being rebooked for Friday again?
I’ve got no BT Email and can’t access BT Wi-Fi which may or may not provide some form of internet service. I’m not counting on anything good from looking at the thousands of bad reviews and poor rates it’s got on the Google Play Store!
Who can I contact to sort out this mess?

It may be because of your settings. You can modify that setting in System Preferences > Trackpad. Another way of making right-click is to click the app icon while holding the Control key

Why can I only order 1 EDGE device when browsing online?

Several EDGE plan / share MORE plan questions from potential customer:
1. Why can I only order 1 EDGE device online when browsing options?
2. I have a large family, especially now that my mother is suddenly unable to live alone. How many total lines and how many EDGE phones are allowed on one plan?
3. Since my mother already has a VZW iphone4, can I add her to the plan at $15 for her line if I buy 10G or more data?
My family has a hodgepodge of plans, since VZW was too expensive compared to other options in the past and some of the older ones have had smart phones longer than others, etc. Ultimately I am trying to find out if I can add 5 EDGE devices, plus one already owned device at the $15 rate for that line, as long as I have 10+ GB of data (probably looking at 12 to be safe).
Is this possible? And can I order online? It's really difficult to make it to a store during hours right now.
Thanks in advance for any assistance!

Thank you both for your help. I have a few follow-up questions for the best path forward if I switch to Verizon for all of our lines--quite a few phones to order and numbers to port form various carriers (StraightTalk, T-mobile prepaid, ATT).
-Can I order the first EDGE phone online, creating my account and porting my number, then wait two days (so that I have received and activated my new phone), then add the next line / EDGE phone / port number, and continue in that fashion?
If not, can I go in person and order multiple phone lines / ports to the EDGE program on the share more everything plan at the same time?
Or,
Can I do a combination--go in person to add my first four lines, then add the others individually online? Is there a time requirement between changes?
Thank you again.

AudioFormat audioFormat = getAudioFormat();
DataLine.Info dataLineInfo = new DataLine.Info(TargetDataLine.class, audioFormat);

The result is
Number of Capture Devices Found: 01- Check your classpath, whether it contains JMF path or not.
2- Check whether JMF is installed correctly or not i.e. are you able to capture using JMStudio? and does JMStudio lists your capture devices?
3- If you are using a jar in Vista, then there is almost NO solution, you will always get 0, check the following threads:

CaptureDeviceManager.getDeviceList returns no devices

Hello,
I have succesfully installed (I think) the logitech web cam pro on my system -- I can use logitech software to see video...and I can also use the following code to get a valid MediaLocator (mediaLocator =new MediaLocator("vfw://0")) , which I can display video in my java program, however the code: (devices = CaptureDeviceManager.getDeviceList ( null );) doesn't return ANY devices!!! (I have also used the JMFRegistry program to "Detect Capture Devices", and it shows up in the list).
Does anyone have any suggestions for me to look into?
Thanks,
Joel

Why can't Apple ever get upgrades right?

More a vent than anything else, but feel free to jump in.
I tried upgrading to iOS 5 tonight, and like every single other uprgade on every single apple device I own and there are a few, it fails. It fails for some just plain stupid reasons that I as an old IT guy just don't understand. To wit:
- Why does the upgrade have to talk to an upgrade server to verify things so often?
Once to verify the checksum on the upgrade file, once after it's applied. The system should never need to call back after that, everything (restore of files, apps etc) should be handled locally. No reason for Apple to verify them, in fact I should be able to do the enotre procedure offline.
- Why can I not download the upgrade on any install of iTunes vs just one?
It's upgrading, not adding or removing anything, so why do I have to clog up a system all night because the family iDevices were all connected here? But that's a whole other issue that's been flogged to death here.
- Why can't we download the files and upgrade the devices offline? See the above question as well.
I'm guessing that given the poor communication with apple's systems and the beating they're probably taking tonight with the verification traffic, someone's got to be thinking about this?
- Why does EVERY change want to delete everything on the device?
So stupid, not even going there. I have to delete eveything on my iPod to add ONE book? Really?
I keep hoping that some time they'll get it right, but now that Steve is gone (RIP good sir) I'm guessing not so much....

Even if you update a Microsoft product it too has to be verified by the host as a legitimate program that can be signed off as genuine. Things happen, though Apple's upgrading is far better than others. Getting frustrated with it only makes things worse as you can do things without knowing you clicked the wrong button or forgot to press a button.

Why has Premier stopped recognizing my capture device?

I'm capturing HDV from a JVC BR-HD50. Premier was recognizing the device but now all I get when I open the capture window is the message "Capture Device Offline". I don't know what has changed that should affect this.
The computer is recognizing the BR-HD50 as a 61883 Class Bus Device. It is connected through a firewire port.
I can capture with it using Premier Pro 2.0 on another work station, so I know the BR-HD50 is working fine.
Should I maybe uninstall and reinstall Premier, with the device plugged in?

No, I haven't, because I'm not sure when the problem occurred and there have
been quite a few restore points since then. Still, I may try that. Thanks.

I have an iTunes account where I have downloaded Digital movies & I am able to see the list on the desktop of the original downloads. When I log on another device with my login I do not see my list to access them. Why can't I access from another device

Hey GingCarv,
Great question. You'll want to download the movies from your purchase history. The following article explains how to do so:

Note: At this time, movies are not available for automatic downloads.

Why can't I just get rid of the Metro UI altogether?

I don't want it, I just want Windows to function like 7 does, however since you've decided to make DX12 Windows 10 only, I'm going to HAVE to upgrade at some point.
The metro crap is so annoying, like when I right click to disable my Wifi adapter in Network connections, it pulls up the Metro UI............... why? Why can't I right click and have a bar pop up where I've right clicked like how Windows has always done
it. I fail to see how pulling up a different UI in another locations helps at all... just makes more button presses as I then have to do a few more clicks in there to get to where I just was on the Desktop.
Since I have 3 monitors, the Metro UI always opens up on another monitor, which makes it even more annoying.
I just want it all gone, I've never used it, I have no interest in your tablets or phone so I couldn't care less about it. Just give me a plain and simple Desktop for fuck sake!

That assumes Microsoft actually has both the intention and the talent to change it for the better.
Where's the evidence of that?
With the latest build, 9860, we see what changes, exactly, after 3 weeks of work?
Slight tweaks to the theme (which is ugly).
New/adjusted window transition animations (which are annoying and don't handle the drop shadow properly).
A new Notifications window that appears BEHIND an auto-hidden Taskbar.
A prototype zPC Settings app that implies they're re-implementing the control panel in Metro/Modern.
Event messages that are virtually all undocumented.
No build symbols available on the Microsoft online symbol server.
A Task Manager that still won't remember what tab it was last on.
Gargantuan CPU and GPU power and we still can't resize a Metro/Modern app to be small.
Ask yourself: Do we see ANY evidence at all that Microsoft has made ANY direction change from pursuing that which caused Windows 8 to fail?
Where is the innovation? Where is the effort? I'm just one engineer and I can tell you my own software products have changed more in the past 3 weeks than Windows has.

Why can't I buy a apple device with my iTunes account money?

Why can't I buy something like the new iPod touch with my iTunes money. I don't get why because they are from the same company. This is puzzling so I need some help if anyone can give me and answer that would be great.

Because the itunes store, where you have credit, does not sell ipods.
Whether you understand it or not, you CANNOT use your itunes gift card for Apple Store Purchases.
It is ONLY for itunes store purchases.

HT201322 Why can't I hide purchases in devices using iOS 6?

I have just purchased an iPad for my brother to use whilst in hospital. Unfortunately I don’t have enough money to buy him his own. Want him to be able to use some of the apps and purchased movies, but not all of them. Why can't I hide old and crappy apps on iOS 6 on the ipad, but can on my old crappy windows computer in iTunes??

As it says on the page that you posted from it's not currently possible to do it on iOS 6 - as to why not I, I don't think that Apple have said, nor whether it's only temporary.
If I hide an app via my computer's iTunes and close the App Store app on my iPad via the taskbar, then when I re-open the app it's also been hidden from its Purchased tab.

Why can't I see a simulated device in myDAQ assistant?

I have created a simulated device (cdaq 9174) in NI MAX.
I am using the DAQ assistant symbol in labview to create a voltage signal simulation.
When I get to the "select physical channels to add to the task" screen in the DAQ assistant, my simulated device is not showing up, even though I can see it in NI MAX.
Any trouble shooting suggestions?

Hi Dawud,
you should stick with your original thread instead of scattering the problem in different places…
Did you also simulate some modules in this cDAQ chassis?
Why don't you supply a MAX screenshot with your question?
