Quick Regex question

This is a php Regex, but I have a feeling I can find help here...
I am using this code to convert a [email protected] to <a href="mailto: ..">
I want to modify it so if there's already a <a href="mailto:...> it will not change it
My current code is:
$text = eregi_replace("([_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3})","<a href=\"mailto:\\1\">\\1</a>", $text);Help please.

Very quick regex question

Hi everybody,
I can't seem to figure this out in regex, but can anyone tell me how to use String.split to split a string on every second space?
So, basically, turn this:
aaa bbb cccc dddd eee fff
into:
aaa bbb
cccc dddd
eee fff
Thanks!

I would never have come up with that on my own, but I did try. I have to say, though, I still don't quite understand all of what's going on in that regex. Would someone please mind explaining one more time what the parts are, and what they do?
Thanks so much!
Jezzica85Did you see reply #6? It pretty much sums it up. In order to understand it, you do need to have a basic knowledge of regex though.
Here's some extra info:
a(?=b)       positive lookahead, matches "a" only when followed by "b", see: http://www.regular-expressions.info/lookaround.html
\\s          a white space character
\\S          a non-white space character (anything but a white space character)
$            the end of the line/String

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.

Quick regex "link" question

I need to extract the link and the links anchor text from Strings which take the following format:
Bestsellers
Or
Find Gift
(I.e. has more attributes other than the "href" attribute)
I have the following regex:
<a\s+[^<>]*?href\s*=\s*["'](.*)["']\s*>(.*?)</a>
However, although, this works fine for the first example above, it does not match the second example correctly. Instead the "link" it matches comes out as:
/gp/product/" id="gift" name="findGift
When it should be:
gp/product/
I thought my regex pattern says "extract the link (everything between) the two quotes after "href=" but it seems to match any other attributes which may be inside the "<a>" tag.
Could someone explain where I have gone wrong.
Thanks

Watch out with those .* things. Try this one:
<a\s*href\s*=\s*['"]([^'"]*)[^>]*>([^<]*)</a>

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

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.

Regex question

Hi,
I have a question regarding the regular expressions in java.
Let's say I have the following regex: "(one)|(two)|(three)" and the following string: "two". The string obviously matches the regex, because of the "\2" group. Is there any way to determine the group number that matched the string, without having to use something like:
for (int i = 1; i <= matcher.groupCount(); i++)
}

It's not top secret, the time difference is the problem.
It's for a school project. We have to make Pascal Compiler and the first step is the Lexical Analyzer. This means that I have some regular expressions for identifiers, numeric constants, string constants and so on...
For example the regex for the identifiers (variable name) looks like: "[a-zA-Z_][a-zA-Z0-9_]*", but the one for the key words is basically an array, like the one in my first post.
The regular expressions work fine, but for the next part of the project I need to know the index of the key words, within the key word array (which in my case is a regular expression). So this is why I was wondering if there is any way to get the group number, without having to iterate through the whole regex.

Okay quick easy question for all who have successfully uploaded videos

hi, this is my first post in the Apple forums!

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.

Simple Java regex question

I have a file with set of Name:Value pairs
e.g
Action1:fail
Action2:pass
Action3:fred
Using regex package I Want to get value of Name "Action1"
I have tried diff things but I cannot figure out how I can do it. I can find Action1: is present or not but dont know how I can get value associated with it.
I have tried:
Pattern pattern = Pattern.compile("Action1");
CharSequence charSequence = CharSequenceFromFile(fileName); // method retuning charsq from a file
Matcher matcher = pattern.matcher(charSequence);
if(matcher.find()){
int start = matcher.end(0);
System.out.println("matcher.group(0)"+ matcher.group(0));
how I can get value associated with specific tag?
thanks
anmol

read the data from the text file on a line basis and you can do:
String line //get this somehow
String[] keyPair = line.split(":")g
System.out.println(keyPair[0]); //your name
System.out.println(keyPair[1]); //your valueor if you've got the text file in one big string:
String pattern = "(\\a*):(\\a*)$"; //{alpha}:{alpha}newline //?
//then
//do some things with match objects
//look in the API at java.util.regex
