Possible to get ReadableByteChannel from MulticastSocket???

Hi,
I am trying to get a ReadableByteChannel from a Multicast socket. The MulticastSocket class inherits from DatagramSocket which has a getChannel() method. The channel is always null when I try to use it (I dont' think it is getting initialized properly....see below)
InetAddress group = InetAddress.getByName(hostname);
MulticastSocket s = new MulticastSocket(port);
ReadableByteChannel source = s.getChannel(); // this is always returning null
s.joinGroup(group);
I think the reason it is null is because:
A datagram socket will have a channel if, and only if, the channel itself was created via the DatagramChannel.open method.
I can't figure out how to use this properly. Any ideas???

You are correct. As there is no MulticastSocketChannel (yet), you can't have created one by calling MulticastSocketChannel.open(), so MulticastSocket.getChannel() returns null.
It's coming in 1.7 (finally ...)

Is it possible to get data from a smashed/broken iPod touch 4th gen?

- If when you connect the iPod to your computer it appears in iTunes then you can make a backup and then restore another iPod or other iOS device from that backup.
- Otherwise you will have to go to a data recovery company.
- When I go to the YouTube link I can't get the video to play.

I looks to me that 515 pixels represents 200 meters, so multiply the
x-values by 0.3885 meters/pixel to get the true x-values. I don't
have enough information to scale the y-axis.

Is it possible to get logs from a 3850 Cisco member switch in a stack?

%STACKMGR-1-STACK_LINK_CHANGE: MEMBER: 4 stack-mgr: Stack port 2 on switch 4 is down
%STACKMGR-1-STACK_LINK_CHANGE: STANDBY:2 stack-mgr: Stack port 1 on switch 2 is down (OC-SWTCH)
%STACKMGR-6-SWITCH_REMOVED: STANDBY:2 stack-mgr: Switch 3 has been removed from the stack.
I recieved errors on a 3850 switch 3 in my stack, it's removed from my stack and after 5 minutes it comes back up. I want to know what the switch was doing for those 5 minutes, is it possible to get the log files for only switch 3? Telneting to the switch stack or connecting a console cable directly to switch 3 only gives me the logs for master switch logs. Ideally when a switch reconnects to a stack, the master switch should ask the joining switch for it's logs, and merge them into it's own logs so it has a record of the switch did when it wasn't communitating.

IS Possible to get information from GetUserProfileByName inside of repeat section

IS Possible to get the values from GetUserProfileByName inside of repeat section? by Codeless
and then with this result used to filter DDL
Or GetUserProfileByName is only useful when it is used for FORM LOAD
CRISTINA&amp MICROSOFT Forum

Hi,
According to your description, my understanding is that you want to use the GetUserProfileByName service in InfoPath form.
We can get information from GetUserProfileByName inside of repeating section, however you need to give the name of user so that the service can be used to get the details of the user.
Please refer to the link below:
http://thinketg.com/using-infopath-and-the-web-service-getuserprofilebyname/
You can create rules to query for data using GetUserProfileByName, and it is not only useful for form load.
Thanks,
Victoria

Possible to get data from a partly optimized/stripped core file?

Hello,
This may not be possible, but I figured it was worth asking about.
I've got a C/C++ GUI application compiled with Solaris Studio 12.3 that is experiencing an infrequent crash when compiled for production and running on production boxes. This is on Solaris 10 for x86 running in 64-bit mode. Most of the app is in libraries which are statically linked.
I working on trying to replicate the issue in a development environment, but have not had luck yet. In any case, it would be interesting to know what kind of data can be gleaned postmortem from the core file I've got access to.
The application is actually a small "main.c" file which is complied and linked in debug mode with "-g" and no optimization, but this thin wrapper calls into the main logic in statically linked libraries which are optimized and not built in debug mode. (See the call stack below.)
From the core file :
1) For functions in the call stack that have names, can I get the value of one of the parameters? I ask because several such functions take pointers to structs with data that should be very useful.
2) For functions in the call stack that appear as ??????, is it possible to determine at least what .o or .a file they came from? This could help narrow things down.
Some basic Googling indicates that either of the above may not be trivial or even possible. But I'm wondering if the fact that we've got a "main.c" debuggable wrapper might somehow help.
As a related question, pstack produces sensible output, but dbx shows the error: "dbx: internal error: could not iterate over load objects -- link-maps are not initialized". Is there some flag I need to supply to dbx?
Thank you for any help,
David
Background info:
I've been unable to replicate on non-production deployments, but the machines do differ a bit.   Eventually I will be able to borrow a production box to deploy an instrumented binary, but for now all I've got is a core file and access to source.
The core was generated with gcore while the app was displaying a popup from it's SIGABRT cleanup handler.   The production build scripts do some binary stripping, but I'm not yet sure where it is getting done.
Here is the (slightly cleaned up) output of pstack for the core file:

>1) For functions in the call stack that have names, can I get the value of one of the parameters? I ask because several such functions take pointers to structs with data that should be very useful.
Use compiler option -preserve_argvalues={none|simple|complete} to preserve incoming argument values. Note that this feature was introduced in Oracle Solaris Studio 12.4.
You may also be interested in a new option in Oracle Solaris Studio 12.4 which provides much finer-grained control over debug information, which allows you to choose how much information is provided and to reduce the amount of disk space needed for the executable. Dev Tip: How to Get Finer-Grained Control of Debugging Information.
>2) For functions in the call stack that appear as ??????, is it possible to determine at least what .o or .a file they came from? This could help narrow things down.
The following 2 commands may help:
where -l
# Include library name with function name.
whereis -a <addr-of-?????> # Print location of an address expression
>As a related question, pstack produces sensible output, but dbx shows the error: "dbx: internal error: could not iterate over load objects -- link-maps are not initialized". Is there some flag I need to supply to dbx?
This may be caused by corefile mismatch. See dbx online help: "help core mismatch" for suggestions.
Hope this helps.

Hard-drive Crash!! - Possible to get files from Apple TV to my new hdd?

My hard-drive just crashed and I just received the new hard-drive. I was wondering if there is a possiblity to restore into my new hard-drive the files I had downloaded from my old hard-drive to my apple TV. I have a alot of music, photos etc on my apple tv hard-drive, I hope there is a way to restore the files back to my new hard-drive.
Thank you.

there is no easy way... people need to realize that appleTV is not a backup drive and with all the valuable, irreplaceable things on your computer you need to have a backup strategy... can you really afford to lose everything on your computer? don't buy one hard drive, buy two... one to replace the dead one and one for a backup drive or buy a hard drive and a time capsule (with time capsule you can do wireless backups from your macbook).
getting the files off would involve breaking your warrantee...
1) taking the appleTV apart (not an easy task, but you can find instructions online), removing the hard drive, hooking it up to your computer... by putting it into a USB enclosure or eSATA or internally
2) hacking your appleTV (instructions online) SSHing to it and getting the files off that way...

Possible to get length from midi files?

Is it possible to retrieve the length from a midi file, for example in miliseconds?

And how is that helping me?So my taking my limited free time to consider your question, do a search on google, and pull up a very appropriate article -- all as a volunteer mind you -- is not helpful?
A word of advice: you will have a much greater chance of getting more help if you show appreciation for anyone who takes the time out to consider your problem and offer any even remotely useful solution.
just my 2 Shekel's worth...
It explains how MIDI format is built...
I am no pro as you may understand, because I posted
in "New To Java".And I can magically read your mind and know exactly where you are in your java development? Sorry, I left my mind-reading cap at work. You were not exactly detailed in what you were seeking, what you know, and what you've found so far. Another word of advice: try to put as much effort into asking your question as you'd like someone would to answer it.
And I know you can get length of .wav files for
example by using Clip. That's why I am asking if
there's a way for midi files as well. Like a method
for AudioStream or whichever.I hope you find your method. But this is all the help you are going to get from me. Geeze...

Is it possible to get music from iPod to iTunes?

THis question is not as stupid as it sounds. I recently had to purchase a new computer because my old one with all my music files crashed. I have all my music files on my iPod and wanted to know if there was anyway I could take them off my iPod and put them all into the iTunes on my new computer. I also had my iPod to synch with iTunes and I want to turn that option off but I am not sure how to. If anyone knows the answers to either of these questions your help would be greatly needed. Thanks!

Connect your iPod to your computer. If it is set to update automatically you'll get a message that it is linked to a different library and asking if you want to link to this one and replace all your songs etc, press "Cancel". Pressing "Erase and Sync" will irretrievably remove all the songs from your iPod. Your iPod should appear in the iTunes source list from where you can change the update setting to manual and use your iPod without the risk of accidentally erasing it. Also when using most of the utilities listed below your iPod needs to be enabled for disc use, changing to manual update will do this by default. Check the "manually manage music and videos" box in Summary then press the Apply button: Managing content manually on iPod
Once you are safely connected there are a few things you can do to restore your iTunes from the iPod. If you have any iTunes Music Store purchases the transfer of purchased content from the iPod to authorised computers was introduced with iTunes 7. You'll find details in this article: Transfer iTunes Store purchases using iPod
The transfer of content from other sources such as songs imported from CD is designed by default to be one way from iTunes to iPod. However there are a number of third party utilities that you can use to retrieve the music files and playlists from your iPod. You'll find that they have varying degrees of functionality and some will transfer movies, videos, photos, podcasts and games as well. Have a look at the web pages and documentation, this is just a small selection of what's available, they are generally quite straightforward. You can also read reviews of some of them here: Wired News - Rescue Your Stranded Tunes
TuneJack Windows Only
iPod2PC Windows Only
iGadget Windows Only
iDump Windows Only
iRepo Mac and Windows
iPodRip Mac & Windows
YamiPod Mac and Windows
Music Rescue Mac & Windows
iPodCopy Mac and Windows
There is also a manual method of accessing the iPod's hard drive and copying songs back to iTunes on Windows or a Mac. The procedure is a bit involved and won't recover playlists but if you're interested it's available at this link: Two-way Street: Moving Music Off the iPod
Whichever of these retrieval methods you choose, keep your iPod in manual mode until you have reloaded your iTunes and you are happy with your playlists etc then it will be safe to return it auto-sync. I would also advise that you get yourself an external hard drive and back your stuff up, relying on an iPod as your sole backup is not a good idea and external drives are comparatively inexpensive these days, you can get loads of storage for a reasonable outlay.

HT3302 I recently fried my iPhone 3GS in water. Is it still possible to get pictures from the SIM card and transfer them to my new iPhone 5s?

I recently fried my iphone3gs from accidental water submersion . Is it possible to retrieve any photos from the some card and transfer to my new iphone5

It depends on what kind of sim card and carrier you have, but the most likely answer is no. Contacts, maybe, but pictures are very unlikely. Sorry.

Not possible to get software from Apple support

This is no way to start friday.

(Firefox is better anyway. Grinners.)

Is it possible to get hacked from safari on your Iphone

When I was browsing a site a white badge icon popped up and asked if I wanted to go to a site. Assuming that this was malicious I went to take safari off multitask. When I did that my screen went black w/the white apple logo and a few seconds later my normal locked screen appeared. When I went back into my phone I assumed it was a virus and cleared all the cookies/history from safari. After that I spent the next couple of hours downloading avast and resorting my phone. My only concerns are if they hacked me and stole any information from my phone (that being the reason I restored my phone). My question to you guys is has this ever happened to you guys and should I still be concerned? Its been a day and I'm still shaken up.

Unless your iPhone has been jailbroken there is nothing known that can attack the iOS...and be sure to download the latest iOS, 7.0.6 as that has security patches and SSL patches.
There can be browser pop-ups, but those are from the website and not things that can self-install on an iOS device. They can be a scary thing to deal with, however. Basically what you did is great...I would not bother with anything like Avast. With an experience like that, double click the home button, dismiss all recent apps by swiping the material above the icon up and away, then reboot by holding both the power and home buttons until the apple logo appears. Ignore the red slider if that appears.
Doing that stops all apps that could be running even in the background, clears all memory, and resets the iOS device. No data or settings will be affected by doing that.
