2 quick Lion questions

1) I had a folder as a shortcut in my side bar, when I upgraded to Lion the shortcut won't work. It gives no response. I tried to drag out and delete it but it won't work. I created the shortcut again and it works, but the old one just wont go away. how can I make it go away? See the picture
2)I know I can clean install Lion from the Lion partition created, but will it redownload the 4GB file, or all files neceesarry are on the disk?
I don't want to wait 2-4 hrs for another download.
thanx

You can access the Recovery Partition by holding command + r keys upon rebooting.
The Lion Recovery Partition does require a Internet connection (and Apple ID) to redownload the installation files.
A Ethernet connection seems to work better than a WIFI
Just reinstalling Lion will overwrite Lion, not your files or programs.
But make a external backup of your files and disconnect regardless.
If you want to erase/format partitions, then use Disk Utility first.

Hi all .hope all is well ..A quick trim question

Hi all
Hope all is well ......
I have a quick trim question I want to remove part of a string and I am finding it difficult to achieve what I need
I set the this.setTitle(); with this
String TitleName = "Epod Order For:    " + dlg.ShortFileName() +"    " + "Read Only";
    dlg.ShortFileName();
    this.setTitle(TitleName);
    setFieldsEditable(false);
[/code]
Now I what to use a jbutton to remove the read only part of the string. This is what I have so far
[code]
void EditjButton_actionPerformed(ActionEvent e) {
    String trim = this.getTitle();
      int stn;
      if ((stn = trim.lastIndexOf(' ')) != -2)
        trim = trim.substring(stn);
    this.setTitle(trim);
[/code]
Please can some one show me or tell me what I need to do. I am at a lose

there's several solutions:
// 1 :
//you do it twice because there's a space between "read" and "only"
int stn;
if ((stn = trim.lastIndexOf(' ')) != -1){
    trim = trim.substring(0,stn);
if ((stn = trim.lastIndexOf(' ')) != -1){
      trim = trim.substring(0,stn);
//2 :
//if the string to remove is always "Read Only":
if ((stn = trim.toUpperCase().lastIndexOf("READ ONLY")) != -1){
   trim = trim.substring(0,stn);
//3: use StringTokenizer:
StringTokenizer st=new StringTokenizer(trim," ");
    String result="";
    int count=st.countTokens();
    for(int i=0;i<count-2;i++){
      result+=st.nextToken()+" ";
    trim=result.trim();//remove the last spaceyou may find other solutions too...
perhaps solution 2 is better, because you can put it in a separate method and remove the string you want to...
somthing like:
public String removeEnd(String str, String toRemove){
int n;
String result=str;
if ((n = str.toUpperCase().lastIndexOf(toRemove.toUpperCase())) != -1){
   result= str.substring(0,stn);
return result;
}i haven't tried this method , but it may work...

Quick script question

Hi all,
Could anyone advise me if i can add anything within - header('Location: http://www.mysite.co.uk/thankyou.html'); in the script below so as the page
re- directs back to the main index page after a few seconds ?
Thankyou for any help.
<?php
$to = '[email protected]';
$subject = 'Feedback form results';
// prepare the message body
$message = '' . $_POST['Name'] . "\n";
$message .= '' . $_POST['E-mail'] . "\n";
$message .= '' . $_POST['Phone'] . "\n";
$message .= '' . $_POST['Message'];
// send the email
mail($to, $subject, $message, null, '');
header('Location: http://www.mysite.co.uk/thankyou.html');
?>

Mr powers gave me that script so im rather confused at this point in time
I don't think I "gave" you that script. I might have corrected a problem with it, but I certainly didn't write the original script.
What you're using is far from perfect, but to suggest it would lay you open to MySQL injection attacks is ludicrous. For you to be prone to MySQL injection, you would need to be entering the data into a MySQL database, not sending it by email.
There is a malicious attack known as email header injection, which is a serious problem with many PHP email processing scripts. However, to be prone to email header injection, you would need to use the fourth argument of mail() to insert form data into the email headers. Since your fourth argument is null, that danger doesn't exist.
One thing that might be worth doing is checking that the email address doesn't contain a lot of illegal characters, because that's a common feature of header injection attacks. This is how I would tidy up your script:
<?php
$suspect = '/Content-Type:|Bcc:|Cc:/i';
// send the message only if the E-mail field looks clean
if (preg_match($suspect, $_POST['E-mail'])) {
header('Location: http://www.example.com/sorry.html');
exit;
} else {
$to = '[email protected]';
$subject = 'Feedback form results';
// prepare the message body
$message = 'Name: ' . $_POST['Name'] . "\n";
$message .= 'E-mail: ' . $_POST['E-mail'] . "\n";
$message .= 'Phone: ' . $_POST['Phone'] . "\n";
$message .= 'Message: ' . $_POST['Message'];
// send the email
mail($to, $subject, $message);
header('Location: http://www.example.com/thankyou.html');
exit;
?>
Create a new page called sorry.html, with a message along the lines of "Sorry, there was an error sending your message". Don't put anything about illegal attacks. Just be neutral.
By the way, when posting questions here, don't use meaningless subject lines, such as "Quick script question". If you're posting here, it's almost certain to be a question about a script. It doesn't matter whether it's quick. Use the subject line to tell people what it's about.

Lion Questions

I have several Lion Questions (I hope someone has the answers):
How soon will new Macs ship with Lion preinstalled? And is the ship date the same for Apple Stores as well as other merchants as well?
If a new Mac is bought w/Lion pre-installed what options will I have if I need to replace OS or something within it?
Will Logic Pro X, when it’s released, work under 10.6.8 or just under Lion?
Will Logic Pro X be able to be install on it's own or does it need to see a former version? And if not is it better to transfer the most recent version to a new Mac or should I put on an older disc based program and do a fresh install?

No one knows for sure when Macs will ship with it preinstalled. But if you buy it from an Apple store, it's a free upgrade. I would assume the merchants would sell them the same time Apple retailers do.
I'm a little confused by your second question... but I'll interpret it as this. You want to do a full OS reintallation, but don't have a disc. Lion comes with a dedicated partition specifically for this. It has a built in "recovery" partition.
As far as Logic Pro X, I'd assume (since Apple creates it) that it will work with 10.7. I'd contact Apple for more details on upcoming software.

Urgent help with quick translation questions

Hello,
I am somewhat new to Java. I have a translation to hand in in a few hours (French to English). Argh! I have questions on how I worded some parts of the translation (and also if I understood it right). Could you, great developers, please take a look and see if what I wrote makes sense? I've put *** around the words I wasn't sure about. If it sounds strange or is just plain wrong, please let know. I also separated two terms with a slash, when I was in doubt of which one was the best.
Many thanks in advance.
1) Tips- Always ***derive*** the exceptions java.lang.Exception and java.lang.RuntimeException.
Since these exceptions have an excessively broad meaning, ***the calling layers will not know how to
distinguish the message sent from the other exceptions that may also be passed to them.***
2) The use of the finally block does not require a catch block. Therefore, exceptions may be passed back to the
calling layers, while effectively freeing resources ***attributed*** locally
3) TIPS- Declare the order for SQL ***statements/elements*** in the constant declaration section (private static final).
Although this recommendation slightly hinders reading, it can have a significant impact on performance. In fact, since
the layers of access to data are ***low level access***, their optimization may be readily felt from the user’s
perspective.
4) Use “inlining.”
Inlining is a technique used by the Java compiler. Whenever possible, during compilation, the compiler
copies the body of a method in place of its call, rather than executing a ***memory jump to the method***.
In the example below, the "inline" code will run twice as fast as the ***method call***
5)tips - ***Reset the references to large objects such as arrays to null.***
Null in Java represents a reference which has not been ***set/established.*** After using a variable with a
large size, it must be ***reassigned a null value.*** This allows the garbage collector to quickly ***recycle the
memory allocated*** for the variable
6) TIPS Limit the indexed access to arrays.
Access to an array element is costly in terms of performance because it is necessary to invoke a verification
that ***the index was not exceeded.***
7) tips- Avoid the use of the “Double-Checked Locking” mechanism.
This code does not always work in a multi-threaded environment. The run-time behavior ***even depends on
compilers.*** Thus, use the following ***singleton implementation:***
8) Presumably, this implementation is less efficient than the previous one, since it seems to perform ***a prior
initialization (as opposed to an initialization on demand)***. In fact, at runtime, the initialization block of a
(static) class is called when the keyword MonSingleton appears, whether there is a call to getInstance() or
not. However, since ***this is a singleton***, any occurrence of the keyword will be immediately followed by a
call to getInstance(). ***Prior or on demand initializations*** are therefore equivalent.
If, however, a more complex initialization must take place during the actual call to getInstance, ***a standard
synchronization mechanism may be implemented, subsequently:***
9) Use the min and max values defined in the java.lang package classes that encapsulate the
primitive numeric types.
To compare an attribute or variable of primitive type integer or real (byte, short, int, long, float or double) to
***an extreme value of this type***, use the predefined constants and not the values themselves.

1) Tips- Always ***derive*** the exceptions java.lang.Exception and java.lang.RuntimeException.***inherit from***
***the calling layers will not know how to
distinguish the message sent from the other exceptions that may also be passed to them.***That's OK.
while effectively freeing resources ***attributed*** locally***allocated*** locally.
3) TIPS- Declare the order for SQL ***statements/elements*** in the constant declaration section (private static final).***statements***, but go back to the author. There is no such thing as a 'constant declaration section' in Java.
Although this recommendation slightly hinders reading, it can have a significant impact on performance. In fact, since
the layers of access to data are ***low level access***, their optimization may be readily felt from the user’s
perspective.Again refer to the author. This isn't true. It will make hardly any difference to the performance. It is more important from a style perspective.
4) Use “inlining.”
Inlining is a technique used by the Java compiler. Whenever possible, during compilation, the compiler
copies the body of a method in place of its call, rather than executing a ***memory jump to the method***.
In the example below, the "inline" code will run twice as fast as the ***method call***Refer to the author. This entire paragraph is completely untrue. There is no such thing as 'inlining' in Java, or rather there is no way to obey the instruction given to 'use it'. The compiler will or won't inline of its own accord, nothing you can do about it.
5)tips - ***Reset the references to large objects such as arrays to null.***Correct, but refer to the author. This is generally considered bad practice, not good.
Null in Java represents a reference which has not been ***set/established.******Initialized***
After using a variable with a
large size, it must be ***reassigned a null value.*** This allows the garbage collector to quickly ***recycle the
memory allocated*** for the variableAgain refer author. Correct scoping of variables is a much better solution than this.
***the index was not exceeded.******the index was not out of range***
The run-time behavior ***even depends on compilers.***Probably a correct translation but the statement is incorrect. Refer to the author. It does not depend on the compiler. It depends on the version of the JVM specification that is being adhered to by the implementation.
Thus, use the following ***singleton implementation:***Correct.
it seems to perform ***a prior initialization (as opposed to an initialization on demand)***.I would change 'prior' to 'automatic pre-'.
***this is a singleton***That's OK.
***Prior or on demand initializations***Change 'prior' to 'automatic'.
***a standard
synchronization mechanism may be implemented, subsequently:***I think this is nonsense. I would need to see the entire paragraph.
***an extreme value of this type******this type's minimum or maximum values***
I would say your author is more in need of a technical reviewer than a translator at this stage. There are far too serious technical errors in this short sample for comfort. The text isn't publishable as is.

Quick NativeWindow questions.

Hi,
Two Quick Questions about native window actions (I am using AIR with HTML and JS):
1. How do you "refer" to minimize button ? - So, when a user clicks minimize, it should do an action defined in javascript.
2. How to define click event for System tray icon ? - So I can display something when my system tray icon is double-clicked.
Thanks.

1. Add an event listener to the window.nativeWindow object, listening for the NativeWindowDisplayStateEvent.DISPLAY_STATE_CHANGING or DISPLAY_STATE_CHANGE events.
2. Add an event listener to your SystemTrayIcon object. You can listen for click, mouseUp or mouseDown events, but doubleClick events are not dispatched by this object.

Mail in Mt. Lion question

Seems that Mail app won't play my incoming mail sound each time I close it and open it again, especially when I put it to sleep at night. I have to quit it and reopen it to get the sound to play. Is this an Apple problem or MY problem? Any suggestions?
TIA,
Connie

Bumping this up because I've received no response and perhaps someone out there might know. I don't think I've ever not had a question answered here before.
Anyway, when I my iMac at night and wake it up in the morning, there are no sounds at all—incoming or outgoing—until I quit Mail and reopen it. Is this a flaw with Mt. Lion? What might be the problem?

Newbie reinstall mountain lion question.

Greetings... I own a Macbook pro Retina 15 Inch early 2013, with Mountain Lion OS X 10.8.5 (12F2501). I would like to format it and install a new out of the box OSX (Mountain Lion). My question is that if I re-install the software from the internet as it is mentioned elsewhere, would I get Mountain lion or Yosemite. As I don't want to upgrade to Yosemite yet.
Thanks...

To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase a redemption code at the Online Apple Store: OS X Mountain Lion. Mountain Lion is $19.99 plus tax. Use the code to redeem a download of Mountain Lion from the App Store. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later.
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model
             Identifier 5,1 or later.
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later.
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later.
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later.
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later.
         7. Xserve (Early 2009) - Model Identifier 3,1 or later.
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
     Are my applications compatible?

Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
   2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
Use DiskMaker X to put your installer clone onto the USB flash drive. Wait for the process to complete which will take quite some time.
Install or Reinstall OS X from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
      the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
           because it is three times faster than wireless.
This should install the version of OS X that you had installed.

Fresh Install of Lion - Questions

I plan to format my MBP and install Slow Leopord from the disk, then install Lion. I want to start over fresh in order to eliminate some annoying problems I've been having. However, before doing this I have a few questions I hope some of you can help with.
1. iPhone - how do I back up all my iphone content so when I connect it to iTunes on the fresh Lion install that it won't want to erase everything on my iPhone. I want to make sure that when I connect the first time it won't do the whole "You've never connected to this computer before...." Is there a way to back up my iphone content on bot the iPhone and iTunes and somehow put it on the fresh installed computer? (I sure hope that makes sense).
2. iTunes - Can I back up my iTunes media and import it back into the fresh install of itunes? If so, how?
Much Thanks for any help.

Hi PsychTech,
Sounds like you have an Xserve Cluster Node which doesn't come with a CD/DVD drive. How many drive bays does it have?
If it is then you'd be stuck to running 10.5 on it. Mountain Lion will only install on the 2009 Xserve which does have a DVD drive in the top right corner.
To be able to get into the servers you could do the following.. Find a copy of Tiger or Leopard on CD/DVD.. Either create a bootable image of it and start from a USB/Firewire Hard disk. When you boot up DO NOT go to install OS X but instead go to the Utilities menu and you'll find an option to reset the password which will at least get you in. You can do this with the client version or server version of OS X.
Hope that helps

Okay quick easy question for all who have successfully uploaded videos

hi, this is my first post in the Apple forums!
my quick question:
I have Quicktime Pro, and am currently exporting a video to the iPod
but it is taking an unusually long time...
is this normal (and by long I mean I'm @ 16% and it has been 5 minutes)
do I just need to be more patient?
thanks
^_^

don't say that...
I successfully uploaded videos to my iPod I just was not doing it right
my question has been answered already so STOP BRINGING IT UP AGAIN
also, look... many people just got their iPods today and are kinda anxious to see the video capibilities work on them, so If you do not have anything constructive to say (by calling us n00bs), then I suggest you don't say anything at all

Quick Easy Question About N580GTX-M2D15D5 Bios

Hey guys!!
I just have a real quick and easy (i suppose) question!
I had bios version KH0, and MSI live update found KH1, i downloaded and flashed successfully (DOS window said please restart and press any key to exit) so i did, restarted my computer, and MSI live update utlity and gpu-z and MSI afterburner are all reporting the same bios version i had with the KH0, version 70.10.17.00.01 & date November 09, 2010
MSI live update is not picking up the update again, so my question is, how do i know if it flashed correctly since the bios date and version remained the same?
Thanks !

TDMS - Quick winning Question....

We are reviewing TDMS
We have one quick question ....
After 4 years of Journey & age of landscpae, becuase of SPDD & SPAU was not handled incidentally during "different" patch upgrades. and we assume there is slight inconsistency of " Repository objects" " Dictionary Objects"...
We want to acheive In short
We want to build a Development System which should be in synch of " Repository objects" " Dictionary Objects"... with out any master & application data with TDMS ?
Can we acheive this or not ...
TDMS provides all other luxuries, but we could get a straight confirmation as requirement as above.
Pl Help
Regards
PR

Hi Sriniwas
If you are asking this question to make a buying decision about TDMS then i would suggest that you get in touch with your SAP customer engagement manager (account manager) and ask him to present you all the capabilities and functionalities of TDMS.
Current version of TDMS offer multiple options and functionalities which may be useful for you.
Now regarding the query that you have asked -
If I understood you correctly you are looking for a functionality using which you want to create a development system which is a copy of your production system such that only repository gets copied over from production to the development system and all the client dependent application data is filtered. In the end you will have your development system which is in perfect sync as far as repository and DDIC is concerned.
The above can certainly be achieved using the TDMS Shell process within TDMS. TDMS Shell is also used as a process to prepare your receiver system for TDMS data transfer.
I hope this info helps

Quick naming question

Wasnt sure if its a naming issue or not but Ive never ran into the problem and Im not sure how to describe it....so here goes.
Question: Is there a way to insert a string into the name of a component name and have java see it as the actual component name. (see that question still sounds incorrect)
What I mean is......
you have 10 buttons named oneB, twoB, threeB,......tenB
I need to either change a whole lot of code and make what I want to be simple, very large and complex or, find a way to....
"one"B.setLocation(whereverNotImportant);
or
(someObject.getString( ) ) + B.setLocation(whereverNotImportant);
It looks really odd to me. If theres a way to do it, it just saved me a lot of annoyance.....if not well, Im gonna need more energy drinks.

Quick Notation Question - Data Rates/Frame Rates/Interlacing

Finally upgraded to a decent prosumer camera and I'm trying to decipher what the manual is telling me about the many different formats it shoots and and the associated options. I keep seeing things like "There are two basic shooting modes: 720p and 1080i/p.", which I'm finding confusing. In my understanding, the "p" in 720p means progressive video and the "i" in 1080i means interlaced. So what do I make of 1080i/p?
On top of this, my camera shoots in "native" mode, which drops duplicate frames used in "over 60" formats. This will give me variations in the notation like:
720/24pN
720p Native 60 fps
1080i/24p
1080/24PN
Can someone give me a quick primer about frame rate vs data rate and explain how to read these notations? I'd appreciate it quite a bit.
Thanks!

There are so many cameras, capable of so many different formats that providing a manufacturer and model could be helpful in this discussion.
Jim's answer is absolutely correct but I'm going to re-state for clarification.
The i/p designation means you can chose to record as interlaced or progressive for a given resolution.
It sounds like your camera is designed to "capture" images at 60 frames per second, selecting "native" mode means extra frames are deleted and only the desired frames, based on frame rate setting, are recorded to memory. The advantage of "native" @ 24fps is you save space on your memory card. The advantage of NOT using "native" mode is that all 60 frames per second are recorded, but the file metedata tells playback software to only show the frames needed for the specified frame rate (i.e. 24). Since all 60 frames per second are recorded, you use more memory but you also have the option of retrieving all the those frames, if you so desire, at a later time (i.e. for smoother slo-mo).
To be honest I don't know what your spec of 1080i/24p means. If that is truly an option then I would guess it means it will record a 24p image but the metedata would indicate the file should playback at 30fps interlaced by adding the proper 3:2 pulldown. This would give you that "film" look in a broadcast compatible format.
For the most part, you don't want use use any interlaced settings. Very few display devices still in use can properly display interlaced images. Interlacing is only required in some broadcast specifications.
To answer the second part of your question;
Frame rates are an indication of how many times the moving image is captured over a given period (per second). Higher frame rates means smoother, more "real life" motion. Data rates can generally be considered an indication of image or audio quality. Higher levels of compression result in lower data rates and (generally) lower quality. If squeezing more hours of footage on fewer memory cards is more important than getting the best image quality, choose a lower data rate. Higher frame rates (more images per second) inherently require a higher data rate to retain the same quality as fewer frames at a lower data rate.
