How to use short[] someDescriptorTags
I have a problem concerning implementation of SI, and I need your help desperately.
lots of method in interface from SI have a parameter used to filter descriptor tag. Taking the SIDatabase class for example, the class has a method: retrieveSINetworks(....,short[] someDescriptorTags), I don't know how to use the parameter when implementing
the method. In my opinion if the someDescriptorTags==null, I won't put any descriptors into cache. if the someDescriptorTags has " -1" as its only element, i put all descriptors into cache. otherwise, i only put the application interested descriptors specified by someDescriptorTags into cache. is that correct?
Basically, yes. The methods that you are thinking about use the someDescriptorTags parameter to provide hints about the descriptors that the application is interested in (which it will retrieve later using SIInformation.retrieveDescriptors().
You can choose to ignore these hints and not cache any descriptors, or you can choose to cache all of them, but it's best to cache at least the ones that the app is interested in. Not doing this is OK, but it will means that application performance will suffer in this area and that your implementation may not be as good as some other implementations on the market.

How to use short cut in MacBook Pro
I cannot set short cut key on action, please advise method,
Thanks!!Details please.
And screenshots can be so useful to clarify a question (one can use the camera-icon to attach images).
Anyway, you don’t get the option to select a Function Key in the Action Options or is the key not displayed in the Actions Panel after setting one? -

How to Use Home+End Key on new short usb apple keyboard on XP
How to Use Home+End Key on new short usb apple keyboard on XP
now i use macbook and new short apple keyboard.
it hasn't Home and End key. i try to use Fn + -> , Fn + <-
it cann't do that. How can i set the Fn + <- be Home key
and Fn + -> be End key like on my macbook keyboard
thank you for answerEasy, no need to be harsh. I might not be a Level 9 Discussions user, but I’ve been an Apple Technician for more than a decade now. So believe me, I know what I’m talking about. Be it OS X Server or emptying the Trash. But even I come here from time to time to learn from others. Well, back to topic and being a little more specific:
The 'My Info' setting always belongs to the first iCloud account you add to an iOS device. In this account you create at least 1 contact, the one you will be using for 'My Info'. You then do the same on your other iOS device using NOT the same iCloud account, of course. You only need to enable contacts syncing in iCloud preferences for these primary accounts. From here on you can use differing 'My Info' on your 2 iOS devices without a problem.
But you may know that you can use more than one iCloud account at a time. Only the primary one will offer all iCloud options like Photostream. But what they all offer is contacts, calendars, etc. So if you intend (and I did) to share these 2 between your devices you can add them using a second iCloud account to both of your iOS devices. This makes it 3 accounts all in all. You could even go further and add another one just for 'Find my iPhone' if you like.
I would’ve used the built-in sharing of Calendar.app instead, but Contacts.app does not (yet) offer sharing contacts with others. That’s why I went with the third iCloud account as a secondary account to both iOS devices.
Apple of course recommends using just one Apple ID for everything to make it easier. But in some scenarios this just won’t cut it, which is even described in one of their support documents.
I hope that now you have an idea what I’ve done…
Good night
Björn
PS: It would be nice if people did not insist on being right. They too can sometimes learn something! -

hi yesterday i downloaded a software from i tunes for keyboard short cut and i don't know how to use them and install them, how to use keyboard shorts bought from i tunes
You can install it on your iOS device (iPad, iPhone, iPod Touch) either by redownloading it directly on the device via the Purchased tab in the App Store app on it, or by connecting the device to your computer's iTunes and syncing it to it.
Syncing apps from a Mac : iTunes 11 for Mac: Sync and organize iOS apps
from a PC : iTunes 11 for Windows: Sync and organize iOS apps
As to how to then use the app, if the description on the app's description page in the store doesn't describe how to use it in enough detail, then is there a link to the developer's website on its description page, and does that have details ? -

Is the plus sign really not available on your keyboard at the place indicated on this graphic (to the right of the L key)? You might need to use shift or alt/option or shift+alt/option.

Okay so I set up my Time Capsule already and is now backing up 2 of my iMacs. Works great. What I want to know is how to use the TC to directly store files? I want to do this to delete some files on iMac 20inch but still have them on the TC for future reference..eg some movies on iTunes. I want to directly save them on the drive so I can delete them from iTunes and gain some storage. (Ps on iMac 20 inch (it's almost full - 320 GB) when I enter time machine, a tab comes up on finder which reads "Time Machine backups" it's able to be ejected like a disc or a connected device. On the iMac 20 inch, I dragged some files onto there as if using it like a hard drive. Is this the correct method? Then I went to my 27inch iMac and saw the "Time Machine Backups" hoping to see the files I dragged from the 20inch iMac. But the files were not there except a folder that said "Backups.backupdb". Can someone help me?
It's not a good idea to use a network disk for both Time Machine backups and other things. By design Time Machine will eventually consume all the space on its output disk, which will then cause problem for your other files. I'd store those other files on an external disk connected to the Time Capsule. The problem with that is that Time Machine will only back up files that are local to your Mac. That means that you'll only have one copy of the files on or attached to your Time Capsule.

JNI - How to use the error reporting mechanism?
I've developed a C++ DLL which is loaded from a commercial Win32 application (not written by me) as a plug-in for external calculations. On its initialization the C++ DLL launches the Java VM via the JNI invocation interface. When the DLL functions are called by the application, they forward the calls to Java objects inside the Java VM, again via JNI invocation interface.
This works well, but I have encountered a weird error.
From Java I open a JFrame containing a JTextArea as small console for debug output messages. If I turn output to this debug console off (my printToConsole routine checks whether a boolean flag is set), the string concatenation operator may lead to a crash of the Java VM.
For example, if in one of the Java functions called from the
DLL via JNI invocation interface the following is the first statement,
it leads to a crash of the Java VM and the application that loaded the C++ proxy DLL.
String test=""+Math.random(); // String test not used later
Interestingly, if I comment this statement out, the Java code works fine WITHOUT any crash. I've already thought about potential races and synchronization issues in my code, but I don't see where this is the case. And the string concatenation error fails as well, if I insert sleep() statements in front of it and at other places in the code. However, if I turn on log messages printed to my JFrame debug console (containing a JTextArea), the String concatenation works without problems.
So maybe the JNI interface has a bug and affects the Java VM; I don't see where my JNI code is wrong.
One problem is that I do not get any stdout output, as the C++ proxy DLL is loaded by the Windows application, even if I start the Windows application from the DOS command line (under Windows).
Does anyone know how to use the error reporting mechanism?
http://java.sun.com/j2se/1.4.2/docs/guide/vm/error-handling.html
Is it possible that the JVM, when it crashes, writes debug information about the crash into a file instead of stdout/stderr?
My C++ proxy DLL was compiled in debug mode, but the commercial application (which loaded the DLL) is very likely not.
I do not know hot to find the reason why the String concatenation fails inside the Java function called from the C++ DLL via JNI.Yes, I've initially thought about errors in the C++ code too. But the C++ code is actually very simple and short. It doesn't allocate anything on the C++ side. It allocates a couple of ByteBuffers inside the Java VM however via JNI invocation interface calls of env->NewDirectByteBuffer(). The native memory regions accessed via the ByteBuffers are allocated not by my own C++ code, but by the program that calls my DLL (the program is Metastock).
The interesting thing is that everything works fine if output to my debug console is enabled, which means that in the Java print routine getConsoleLoggingState() returns true and text is appended to the jTextArea.
static synchronized void print(String str)
{ MetaStockMonitor mMon=getInstance();
if ( mMon.getFileLoggingState() && mMon.logFileWriter!=null) {
mMon.logFileWriter.print(str);
mMon.logFileWriter.flush();
if ( mMon.getConsoleLoggingState() ) {
mMon.jTextArea1.append(str);
Only if output to the JTextArea is turned off (ie. getConsoleLoggingState()==false), the crash happens when the FIRST statement in the Java routine called via JNI invocation interface is a (useless) String concatenation operation, as described above.
String test=""+Math.random(); // String test not used later
Moreover, the crash happens BEFORE the allocated ByteBuffer objects are accessed in the Java code. But again, if console output is turned on, it works stable. If console output is turned off, it works when the (useless) String concatenation operation is removed in the Java routine called from C++.
I've already thought about potential races (regarding multiple threads), but this can be ruled out in my case. It almost appears as if the JVM can have problems when called by the invocation interface (I tested it with Java 1.4.2 b28).
All the calls between C++ and Java go ALWAYS in the direction from C++ code to Java. Unfortunately, there is no special JRE version with extensive logging capabilities to facilitate debugging. And the problem is not easily reproducible either.

I was using Firefox shortly before deciding to restore my previous session (100+ tabs!), but the browser froze and went blank with the "Not Responding" label on top. This happened to me before, and I decided to just quit the session. I knew that I would lose the session I wanted, but I backed up the important session files found in the Mozilla directory (or at least whatever has "session" and "restore" in its name) while the browser was stuck (before quitting).
What I'd like to understand is HOW TO USE these files to get my session back. I've tried replacing the session files with the back-up copies to no avail. Once long ago I managed to recover a session successfully, but with Firefox constantly changing, I may have lost touch with this.
I use Firefox 34 and Windows 8.1, but I'll need others' help in identifying the session backup/restore files I need to use from the ones I backed up.
I believe that the "recovery.bak" is vital, because it contains the tab/page names I was viewing.
I would greatly appreciate whoever would help me in this, especially if they can teach me the proper methods to follow if this ever happens again (which most likely will!)You can look at this post in this MozillaZine forum thread about inspecting a sessionstore file and possibly extract URLs.

How to use oracle fusion middleware for integration project ?
hi all,
in my projects, customer (a bank) already has many applications (bankend & frontend) that are complicatedly connected. I intend to use oracle fusion middleware to integrate all applications and make adding new applications in the future easier. I have worked through documents in the oracle website but I still have no idea how to use oracle fusion middleware to address the requirement, besides oracle fusion middleware includes a bundle of applications I don't know which one I would need.
could anyone give me some instructions ? appreciate your help.

I managed to transfer the music from 1 pc to 1 other pc (it is played perfectly on the other PC (Windows 7- pc) by the newly downloaded and installed iTunes, version 10.6.1.7). But I didn’t fix the transfer of the meta data (for example the rating). Does anyone know how to use (or import) your old playlists, etc..(= meta data) on the other PC? So, short: how to migrate the meta data from one pc to an other pc?
It's a pity that it seems not to be possible to import on the new pc e.g. the ratings!!!
I don't want to start again with rating my (beautiful classical) music!

How to use the slider to avoid keyframes movements?
Hi there,
first of all, I have to tell, I am not a English speaker, so please excuse me in advance. Anyway, I want to solve this particular issue: I have created an After effects project, where you can add into the composition your own text, logo or whatever... what the after effects project does is, that it turns your text, or logo into the 3D metal result. There is also camera cretaed, which moves from one position, to another. Take a look:
The inputed text is "add content" (I have 4 cameras alltogether, but I am showing an example just on the first one, so you will not see the whole text. The rest of the cameras are also in other compositions)
Here you can see the exact movement of the camera. However, if somebody inserts a logo or a text, which has for example 7 letters (in the next picture it is just "content") it will look like this:
here you can see how big space we have. Also it is not appropriate to change the original size of the text in the composition to achieve the smallest gap, as we can see here. The height will be huge then...
If I would edit it by myself, I would do this:
-I would clicked on the button "2 views" and choose view from the "front"
-Then I would select all the keyframes and after that i would go into the left window "front" and using the mouse I would draged whole the camera to the position I want:
The great thing about this is, that as I selected all the keyframes and then set the red line on one of them, the camrea will work even for the beginning! So this is how it will look after the fix.
What the problem is, that after the small edit I want to send this project to few of my friends. Then they can easily put their text, or logo in. The text will have different height, width...it will be shorter or longer. I was just wondering, if you could help with some expressions, linkings and so on, so in the final result, of one my friends could move with the whole camera (not just with one keyframe) using the SLIDER CONTROL. At least for the x and y axis, if z axis is also possible, it would be brilliant. It also doesn't matter how many sliders there will be .
So basically with using the sliders, they should achieve this:
So i need some helpful steps. Please help me. This is very important for me. I will be so much thankful!! Really! (Thanks for the potential help )You are way over thinking your problem and potentially headed down a path that will cause more problems that it will solve.
If you have a camera path that is already animated and you want to change the position of the camera path as a whole the easiest way to do that would be to create a null and then parent the camera to the null. Move the null and all of the camera movements you have set up will follow. No expressions are needed. This is the easiest way to change every aspect of a motion path, rotate the entire path, scale the path, or move the path on any axis.
If you really want to use 3 position sliders to move existing keyframes to a new value adding value + expressions values will allow you to do this. Just add an three expression control sliders to the camera layer (or any layer like the null you are using as a parent) select the name of the slider in the ECW and press enter and rename it. Something like this will be the result.
Notice that I also have rotation and scale controls in this setup. Now that you have 3 sliders you can separate the position property of the null into individual values enable expressions in each property and type in value +, then use the pickwhip to drag from the X value to your slider named xPosition (in my example) and repeat for each operation. The value + will add the value of the slider to the current value of the position keyframes. The expression will look like this for X:
value + effect("x position")("Slider")
If you want to use sliders I would use a null, add expression controls to the null for position, scale, and rotation, keep the camera position property unified and then use your expression control sliders on the null to modify your existing path. I would not suggest doing this directly on camera position with separated X, Y and Z values because this will change the shape of your camera path and would be more difficult to control. You'll probably also want to create a camera POInull and use this preset to tie the camera's point of interest to the null.
Here's an animation preset you can apply to a null that will give complete control to the motion path of any animated layer you make the child of this null. Search Animation Preset in the After Effects Search Help field if you do not know how to use them, create them, and save them.
As a final gimme, here's a CS6 project using this animation preset to control a null's position that used to change an animated camera path.
