Accessing audio CD information

Some months ago i've tried to implement a small Java application which can query the freedb.org database to request audio disc information like artist name, disk title and track titles of audio CDs.
After implementing the algorithm for computing the freedb key my efforts came to a sudden stop. i could not figure out how to access the necessary information from the audio cd to compute the key via Java. The only solution i figured out was to use platform dependend JNI...
My question is: Is it posible to request audio CD parameters via JMF?
The neccessary information is:
- number of tracks
- time in minutes, seconds and frames of each track

hi,
I'm not an expert in jmf, but if you wanna find the number of tracks, I think you can simply iterate through File.listRoots() with isWritable()==false and then use listRoots()[n].listFiles().length. Then create a Player for each tracks and use Player.getDuration() on them.
I don't know of any direct way to find cd drives.

Mail cannot access your mailbox information because it is in use

I have my mail on a Truecrypt drive and I have an alias pointing to that drive in my library and so sometimes I get this message:
"Mail cannot access your mailbox information because it is in use."
Options are:
"Quit and rebuild Information" or "Quit"
If I rebuild then I was losing all my sent messages which is a drag and it takes a while to re-download all the messages. So what I tried was deleting the Envelope Index.lock file and then launch mail and it started up with no problems.
I think the reason this is happening is that it is possible that when I shut my computer down, Truecrypt dismounts the drive while Mail is accessing the mail folder (hence the lock file) and so when I start up again and remount the truecrypt drive that lock file is still there and I have to delete it or Mail thinks some other program is using the mail folder. Just a guess.
Hope this helps someone else if they Google this error.

I do but I do it from another computer -- that is the whole point of IMAP, by the way. I don't see how my accessing the IMAP server from another computer should cause Mail.app to think that my mailboxes on my local host, which are just copies, need to be rebuilt. I filed a bug on this and Apple gave me the annoying "Known issue" response, which means maybe they'll fix it, maybe not, thank you very much. It went away for a while, and now it's back again... sigh.

Mail keeps crashing because: "Mailbox cannot access your mailbox information because it's already in use."

I have the new MacBook Pro with Retina Display, and my Apple Mail has always worked just fine. About a week ago, I recieve a message saying "Mail cannot access your mailbox information because it’s already in use." The dialogue box gave me the options of "Rebuilding Mailbox Information" or quitting the application. Rebuilding does absolutely nothing, and every time I try to open Mail I get the same response and have to quit. I haven't added any apps or anything that would affect my mail; what's going on? Thanks!

Try this first.

From your statements above, it sounds like you never tried to burn a CD for at least the first year that you owned the laptop, as it had a one year warranty on it. While you might have used it frequently to install software, play DVDs, Blu-Ray disks, etc, that's unclear from your statements. Nonetheless, it might just be dirty-dusty. So, before deleting-uninstalling any software, and given they're cheap, try a CD-DVD Cleaner Disk first and see if that resolves your problems.
Let us know what happens. Good luck.

I unfortunately just got my IPhone 4s stolen.I thought I had the find my iPhone enabled but I didn't because I cannot locate the phone when I sign in ICloud.How can I erase all data on the phone so the thief can't access my personal information.

I unfortunately just got my IPhone 4s stolen.I thought I had the find my iPhone enabled but I didn't because I cannot locate the phone when I sign in ICloud.I have a password on the phone but i'm not sure if I turned on the option where the phone resets if you incorrectly put the password more than ten time. I immediately called my phone company (Verizon) and reported the phone stolen.So I know whoever took the phone cannot place calls or use the phone. But can they still access my data on the phone if they manage to unlock the phone? If so how can I erase all data on the phone so the thief can't access my personal information? is there any other way other than Find my IPhone to wipe off the data on the phone? I really don't want my personal information such as pictures, text messages, notes and social networks profile available to a stranger!!? Help please!!!

Hello thewrongway,
I'm sorry to hear about your phone! I understand the need for an active device. You are able to activate an old device and process an insurance claim for your iPhone 4s within 60days from the incident date. Keep in mind if the old phone is not a smartphone and you currently have unlimited data that feature will fall off. If you have a tier data plan no changes will be made. Please let me know if you have any additional questions. Thank you.

If you know the answers to your security questions for the account, you can reset the password without using email authentication by following the steps in the first section of this article: http://support.apple.com/kb/HT5787. If you don't, you'll need to contact Apple for assistance by going to https://expresslane.apple.com, then click More Products and Services>Apple ID>Other Apple ID Topics>Lost or forgotten Apple ID password.

"Mail cannot access your mailbox information because it's already in use. Rebuild Mailbox information Quit" Both quits Mail.

After installing Yosemite, my Mail stops working after about 20-30 seconds when this Dialog Box pops up, freezes Mail and says:
"Mail cannot access your mailbox information because it’s already in use.
Another application on your computer or on your local network is using your mailbox information. Click Quit to quit Mail. Then log out of this computer and any other computer you’re using. After you log in again, open Mail on one computer only.
If this message reappears, there may be a network server problem. Contact your system administrator to determine if it can be resolved by rebuilding your mailbox information. Then click Rebuild Mailbox Information.
If this message reappears, there may be a network server problem. Contact your system administrator to determine if it can be resolved by rebuilding your mailbox information. Then click Rebuild Mailbox Information.
Rebuild Mailbox information Quit"
Clicking on either one quits Mail. I am receiving my emails. I can even send my self a test email and receive it before it freezes up in 20-30 seconds. My ISP thinks it's a "Kernal" software problem.
Through advice by a friend, I have tried:
Applications - Utililities - Disk Utilities - and selected my hard drive and then click Repair Permissions
Rebooted a bunch of times. The first time Repair Permissions printed a few pages of stuff. The 2nd, 3rd and 4th times, it printed out this:
Repairing permissions for “Macintosh HD”User differs on “private/var/db/displaypolicyd”; should be 0; user is 244.Group differs on “private/var/db/displaypolicyd”; should be 0; group is 244.Repaired “private/var/db/displaypolicyd”
Permissions repair complete
But I still have the same problem I stated the the beginning of this:(
Any more advice?

I have the exact same issue, just after installing Yosemite. Please advise

Hello Snosilla! I'm so sorry for all the confusion and for all the time taken to activate service with us! I do see that the iPhone 5c is $99.99 right now. The iPhone 5s is actually $199.99. There's no need to call Pam anymore, we can take over from here.
I've followed you in the forums. Please accept me, and follow me back. Then, send me a Direct Message and I can look into this for you. If you do not have an active line yet, I may need to get you through to our activations department, but I will do all I can!
Thank you!

Kerberos Configuration Manager for SQL Server: Access of system information failed!

I'm trying to use the new Kerberos Configuration Manager for SQL Server tool that was released recently to verify SPN on several SQL Servers, but any time I attempt to connect to a server I get the following error in the log:
6/24/2013 3:48:22 PM Info: Connect to WMI, \\<HOSTNAME>\root\cimv2
6/24/2013 3:48:25 PM Error: Access of system information failed System.DirectoryServices.AccountManagement.PrincipalOperationException: An error (1332) occurred while enumerating the group membership. The member's SID could not be resolved.

Things I have tried to resolve this:
1. Verified that my account is a Domain Admin.
2. Attempt to connect locally without inputting any information for server/user/pw
3. Attempt to connect remotely using server/user/pw
I always receive the same error message and log: Access of system information failed!
Has anyone else run into this issue?

Update to this:
There were some invalid user accounts added to the Local Administrators group only showing up as a GUID. This caused the enumeration of the group to fail and generate the error in my original post. Removing those user accounts from the Administrators group
got past the enumeration error.
However, now when attempting to connect to the servers (locally or remotely) I get this error:

Accessing SOAP header information in a custom adaptor module

Hi Guys,
Could anyone point me in the direction of information on how to access the SOAP:Header element when writing a custom adaptor module for a http/ SOAP communication channel?
I'm trying to add some WS-Security stuff which isn't available in XI 3.0.
Many thanks,
John

The solution is as follows:
Mark as Do Not Use SOAPEnvelope in the communication channel.
It may be possible to use the SAP implementation of MessageFactory, SOAPEnvelope etc., I forced XI the Apache Axis implementation, a thread on which can be found here Link: [Accessing SOAP header information in a custom adaptor module;
The SOAP Envelope is created by
javax.xml.soap.MessageFactory mf= org.apache.axis.soap.MessageFactoryImpl.newInstance();
This doesn't work it creates a com.sap.engine.services.webservices.jaxm.soap.SOAPMessageImpl
org.apache.axis.message.SOAPEnvelope env = new org.apache.axis.message.SOAPEnvelope();
org.apache.axis.Message iSoapMessage = new org.apache.axis.Message(env);
SOAPMessage sm = iSoapMessage;
SOAPBody iBody = se.getBody();
if(iBody!=null)
     iBody.addDocument(iDoc);
     addDocument failed for some reason when called in XI returning
     Exception caught by adapter framework: Exception in method process.
     The code below is copied straight from the addDocument method, but it works.
     org.w3c.dom.Element iDocRoot= iDoc.getDocumentElement();
     org.apache.axis.message.SOAPBodyElement bodyElement = new org.apache.axis.message.SOAPBodyElement(iDocRoot);
     iBody.addChildElement(bodyElement);
In order to get a document representation of the Envelope you can use
Document iEnvelopeDoc = ((org.apache.axis.message.SOAPEnvelope)env).getAsDocument();
You are now in a position to add or adjust the SOAP Envelope as your require. It enabled me to add WS-Security information to a message.
It is normally possible to use javax.xml.transform.Transformer on the various classes SOAPEnvelope, SOAPBody etc. as they implement Node. However doing this in XI caused a crash.
The final document can be then be set in the xmlPayload before being sent out the door.
Hope this helps someone,
John

Accessing audio file directories more easily

Is there a way to access audio files like foley or music files more easily. Currently I locate files in the finder and drag into the FCP browser window, but would like to have a way to see the various folders in one place. Is this doable, or is there a better way to do this?

Meg The Dog wrote:
Hi =
At the finder level, just use QuickLook.
Select the file. Press the spacebar. If is is an audio file it will play, an image it will display, or a movie it will play as well.
You can use this to sample your files and preselect and screen those you want to drag into the FCP browser.
MtD
Thanks for the feedback. I had hoped there was a way FCP could allow adding folders like Motion's file browser. I know I can add the four or five folders (where I have audio content of interest) to the Finder's Places Sidebar, and sample the audio as you said, but hoped there was a way to do this from within FCP file browser, or access via a right mouse click. I am setting up a Macbook as a mobile editing station, so had hoped there was a way to view and select content without having another window (finder) up. It's less cumbersome of a process with a single monitor system.

As a user of Extract, I would like to have the ability to open/access assets and information contained within smart objects or linked layers. Is this possible?

Problem:
In Extract ( Extract for PSD ) a user is unable to access assets or information from smart objects or linked layers.
Usage:
Smart Objects/Linked Layers are useful for templated web workflows
@Sectioning content allows for a holistic view with access to granular information
Possible Solution(s):
Could we create a link between to cloud files.
Could a smart object or linked layer be expanded on upload
Could we create a drop menu like the layer comps that includes related files

Hello Martin,
Our current support in Extract for Smart Objects includes showing them in the file, and using them on the backend when you request your layer(s) to be scaled while exporting (i.e., when scaling up, the highest quality image is used). We also display the colors, fonts and gradients from the included Smart Objects in the Extract Styles panel.
We have considered providing a way to open Smart Objects from within Extract, and could use some feedback from you on how this user experience would work best for you. Would you prefer option a) or b) below, and why?
a) When opening a Smart Object, it opens in the current browser window, replacing your current view of the PSD.
b) When opening a Smart Object, it opens in a new browser window, which receives focus (is the frontmost browser tab/window).
Also, if you tried to open a Linked Smart Object when the linked file is not available, what would you expect to happen?
Would you describe in more detail what you mean by: "Could a smart object or linked layer be expanded on upload?" and how you'd use this feature?
Regards,
brucebowman
