  i have problems with jquery.. If i have this code to fill tooltip div <div id="tooltip"></div> <div class="tooltipMessage">Tooltip Message</div> <script type="text/javascript"> $("#id").html($("#tooltip").next(".tooltipMessage").html()); </script> Works, the code takes the next element with classname "tooltipMessage" and fills element with id "tooltip".

• How does this code block works?

  - by Justin John

  I can't understand how the following code works. $start = 1; while($start<10){ if ($start&1) { echo "ODD ".$start." <br/> "; } else { echo "EVEN ".$start." <br/> "; } $start++; } The $start&1 will return ODD and EVEN seperately. Output ODD 1 EVEN 2 ODD 3 EVEN 4 ODD 5 EVEN 6 ODD 7 EVEN 8 ODD 9 If we give $start&2 instead of $start&1, it returns with another order. How &1 &2 etc... works here?

• How to change a label's text after loading a html into a dialog

  - by Salsa

  I am opening a modal dialog by loading a form into it. After loading the form, I want to change it's title and one of it's fields' label. I can change the label's text, but after the function returns, the label's text turns back to it's original one. Is it possible to make this kind of change and if so, how? The HTML: <form action="testing.php" method="POST" id="example-form"> <fieldset> <label for="link" id="link-label"></label> </fieldset> </form> The javascript: $(".bt-example").button().click(function() { $('#example-dialog').load('form.html').dialog('open'); $('.ui-dialog-titlebar').text("THIS WORKS!"); $('#example-form #link-label').text("CHANGES AT FIRST, BUT GOES BLANK LATER"); $('#example-dialog').removeClass('invisible'); });

• efficientcy effort: grep with a vectored pattern or match with a list of values

  - by Elad663

  I guess this is trivial, I apologize, I couldn't find how to do it. I am trying to abstain from a loop, so I am trying to vectorize the process: I need to do something like grep, but where the pattern is a vector. Another option is a match, where the value is not only the first location. For example data (which is not how the real data is, otherswise I would exploit it structure): COUNTRIES=c("Austria","Belgium","Denmark","France","Germany", "Ireland","Italy","Luxembourg","Netherlands", "Portugal","Sweden","Spain","Finland","United Kingdom") COUNTRIES_Target=rep(COUNTRIES,times=4066) COUNTRIES_Origin=rep(COUNTRIES,each=4066) Now, currently I got a loop that: var_pointer=list() for (i in 1:length(COUNTRIES_Origin)) { var_pointer[[i]]=which(COUNTRIES_Origin[i]==COUNTRS_Target) } The problem with match is that match(x=COUNTRIES_Origin,table=COUNTRIES_Target) returns a vector of the same length as COUNTRIES_Origin and the value is the first match, while I need all of them. The issue with grep is that grep(pattern=COUNTRIES_Origin,x=COUNTRIES_Target) is the given warning: Warning message: In grep(pattern = COUNTRIES_Origin, x = COUNTRIES_Target) : argument 'pattern' has length > 1 and only the first element will be used Any suggestions?

• Using traversal by pointer to check whether a string is repeated

  - by Bob John

  bool repeat_char(char *s, int n); //R: s is a C-string of at least n non-NUL characters and n > 0 //E: returns true if the first n characters are fully repeated throughout the string s, false // otherwise. I'm having trouble implementing this function using traversal by pointer. I was thinking that I could extract the first n characters from s, then use that in a comparison with s, but I'm not sure how I could do that. If I'm traversing through s one character at a time, how can I check that it matches a block of text, such as the first n characters of s? Thanks!

• Action(Of T) in Visual Basic in List(Of T).ForEach

  - by Jason

  I have searched high and low for documentation on how to use this feature. While the loop I could write would be simple and take no time, I really would like to learn how to use this. Basically I have a class, say, Widget, with a Save() sub that returns nothing. So: Dim w as New Widget() w.Save() basically saves the widget. Now let's say I have a generic collection List(Of Widget) name widgetList(Of Widget) and I want to run a Save() on each item in that list. It says I can do a widgetList.ForEach([enter Action(Of T) here]) ....but how in the F does this work??? There is no documentation anywhere on the intrablags. Help would be much much appreciated.

• In a JDBC ResultSet, what should happen when getLong() or getShort() is called on an int result colu

  - by Uri

  Say that I have a JDBC ResultSet, and I call the getLong() or getshort() method. For which of the following SQL types {SMALLINT, INT, BIGINT} should I get long, and for which types should I get an error? In other words, if I have an INT and I want a SMALLINT (A short), would I get it, or would I get an error? Similarly, if I have an INT and want a BIGINT (a long), would I get it, or would I get an error? The Javadocs (listed below) say nothing. public long getLong(int columnIndex) throws SQLException Retrieves the value of the designated column in the current row of this ResultSet object as a long in the Java programming language. Parameters: columnIndex - the first column is 1, the second is 2, ... Returns: the column value; if the value is SQL NULL, the value returned is 0 Throws: SQLException - if a database access error occurs

• PHP - Get values from Array

  - by danit

  I am trying to get a record from a database using an sql lookup (sql1). This then returns as an array which is fine, but I need to use part of the array for my next stage. $opt=get_records_sql($sql1); //Diags for SQL content print_object($opt); $n = count($opt); if (empty($opt)) { echo 'No options selected'; } else { $optno = $opt["subjectid"]; // Diags of $optno echo '<br>$optno = '.$optno; As you can see, I tried to use this: $opt["subjectid"] as subjectid is the fieldname that I am trying to access and I was under the impression that this was correct for accessing an array, but I get the following error: Notice: Undefined index: subjectid Array contents: Array ( [1] => stdClass Object ( [uname] => JHollands06 [tutor] => M LSt [subjectid] => 1 [year] => 2010 [optid] => 1 ) )

• many-to-many relationship in CI (not using ORM)

  - by Ross

  I'm implementing a categories system in my CI app and trying to work out the best way of working with many to many relationships. I'm not using an ORM at this stage, but could use say Doctrine if necessary. Each entry may have multiple categories. I have three tables (simplified) Entries: entryID, entryName Categories: categoryID, categoryname Entry_Category: entryID, categoryID my CI code returns a record set like this: entryID, entryName, categoryID, categoryName but, as expected with Many-to-Many relationships, each "entry" is repeated for each "category". What would the best way to "group" the categories so that when I output the results, I am left with something like: Entry Name Appears in Category: Foo, Bar rather than: Entry Name Appears in Category: Foo Entry Name Appears in Category: Bar I believe the option is to track if the post ID matches a previous entry, and if so, store the respective category, and output it as one, rather than several, but am unsure of how to do this in CI. thanks for any pointers (I appreciate this is may be a vague/complex question without a better knowledge of the system).

• How to exclude an array of ids from query in Rails (using ActiveRecord)?

  - by CuriousYogurt

  I would like to perform an ActiveRecord query that returns all records except those records that have certain ids. The ids I would like excluded are stored in an array. So: ids_to_exclude = [1,2,3] array_without_excluded_ids = Item. ??? I'm not sure how to complete the second line. Background: What I've already tried: I'm not sure background is necessary, but I've already tried various combinations of .find and .where. For example: array_without_excluded_ids = Item.find(:all, :conditions => { "id not IN (?)", ids_to_exclude }) array_without_excluded_ids = Item.where( "items.id not IN ?", ids_to_exclude) These fail. This tip might be on the right track, but I have not succeeded in adapting it. Any help would be greatly appreciated.

• Why am I getting a MySQL error?

  - by John Hoffman

  Here is my query. Its intention is allow access to properties of the animals that constitute a match of two animals. The match table contains columns for animal1ID and animal2ID to store which animals constitute the match. SELECT id, (SELECT * FROM animals WHERE animals.id=matches.animal1ID) AS animal1, (SELECT * FROM users WHERE animals.id=matches.animalID) AS animal2 FROM matches WHERE id=5 However, MySQl returns this error: Operand should contain 1 column(s). Why? Is there an alternative way to do this, perhaps with a JOIN statement?

• C++ vector that *doesn't* initialize its members?

  - by Mehrdad

  I'm making a C++ wrapper for a piece of C code that returns a large array, and so I've tried to return the data in a vector<unsigned char>. Now the problem is, the data is on the order of megabytes, and vector unnecessarily initializes its storage, which essentially turns out to cut down my speed by half. How do I prevent this? Or, if it's not possible -- is there some other STL container that would avoid such needless work? Or must I end up making my own container? (Pre-C++11) Note: I'm passing the vector as my output buffer. I'm not copying the data from elsewhere.

• grep --include command doesn't work in OSX zsh

  - by icemelon

  I am following the best answer on Finding all files containing a text string in linux to search string in my project. This is my command grep --include=*.rb -rnw . -e "pattern" Zsh tells me that zsh: no matches found: --include=*.rb It seems that grep doesn't support --include option. When I type grep --help, it returns usage: grep [-abcDEFGHhIiJLlmnOoPqRSsUVvwxZ] [-A num] [-B num] [-C[num]] [-e pattern] [-f file] [--binary-files=value] [--color=when] [--context[=num]] [--directories=action] [--label] [--line-buffered] [--null] [pattern] [file ...] no --include here. Is my grep version too old? Or is there something wrong with my command?

If some one has added/updated a user/permissions in next day- if we run a script it should revert all the changes to the previous day status.

This creates lots of problems. On Wednesday if we run a script on the SQL instance and it should reset the database user security back to what it was on Wednesday. Someone please help me in this regard, Its very urgent..............Please..........

• Numeric literals in sql server 2008

  - by costa

  What is the type that sql server assigns to the numeric literal: 2. , i.e. 2 followed by a dot? I was curious because: select convert(varchar(50), 2.) union all select convert(varchar(50), 2.0) returns: 2 2.0 which made me ask what's the difference between 2. and 2.0 type wise? Sql server seems to assign types to numeric literals depending on the number itself by finding the minimal storage type that can hold the number. A value of 1222333 is stored as int while 1152921504606846975 is stored as big int. thanks

• How to get the number of files in a folder as a variable?

  - by Jason

  Using bash, how can one get the number of files in a folder, excluding directories from a shell script without the interpreter complaining? With the help of a friend, I've tried $files=$(find ../ -maxdepth 1 -type f | sort -n) $num=$("ls -l" | "grep ^-" | "wc -l") which returns from the command line: ../1-prefix_blended_fused.jpg: No such file or directory ls -l : command not found grep ^-: command not found wc -l: command not found respectively. These commands work on the command line, but NOT with a bash script. Given a file filled with image files formatted like 1-pano.jpg, I want to grab all the images in the directory to get the largest numbered file to tack onto the next image being processed. Why the discrepancy?

• Codeigniter: how do I select count when `$query->num_rows()` doesn't work for me?

  - by mOrloff

  I have a query which is returning a sum, so naturally it returns one row. I need to count the number of records in the DB which made that sum. Here's a sample of the type of query I am talking about (MySQL): SELECT i.id, i.vendor_quote_id, i.product_id_requested, SUM(i.quantity_on_hand) AS qty, COUNT(i.quantity_on_hand) AS count FROM vendor_quote_item AS i JOIN vendor_quote_container AS c ON i.vendor_quote_id = c.id LEFT JOIN company_types ON company_types.company_id = c.company_id WHERE company_types.company_type = 'f' AND i.product_id_requested = 12345678 I have found and am now using the select_min(), select_max(), and select_sum() functions, but my COUNT() is still hard-coded in. The main problem is that I am having to specify the table name in a tightly coupled manner with something like $this->$db->select( 'COUNT(myDbPrefix_vendor_quote_item.quantity_on_hand) AS count' ) which kills portability and makes switching environments a PIA. How can/should I get my the count values I am after with CI in an uncoupled way??

• Getting country calling prefix

  - by Telkitty

  Just wondering whether there are easy ways to retrieve country calling code from a user's phone. For example, my app would like to pre-fill country calling code for the users. If the user is located in the U.S. the code +1 will be returned, +83 for China, +61 for Australia etc. I had a look around but I could only see: NSLocale *locale = [NSLocale currentLocale]; NSString *countryCode = [locale objectForKey: NSLocaleCountryCnode]; Which returns the abbreviation for the country code, not the calling prefix? Help is appreciated!

• insert into select from other table

  - by user3815079

  I need to add multiple records based on data from another table where the event is the same. I've found on this forum insert into table2(id,name) select "001",first_name from table1 where table1.id="001" as possible solution for my question. So I thought this should be the following syntax: insert into reservations(event,seat) select "99",id from seats where seats.id>0 to add all seats to event 99. However when I run this query mysql gives the message 'MySQL returned an empty resultset (0 rows). (query 0.0028 sec)' and no records were added. I translated the message so could be sligthly different. When I only use the "select "99",id from seats where seats.id0" query, it returns me 1080 rows.

• Why does the return statement not print anything to the console?

  - by dyoverdx

  I Googled it and I didn't hit anything useful, so I decided to ask on here. I can't use System.out.println for the project that I am working on, so I used the return statement. Everything compiles just fine, but my return statement doesn't print anything to the console, the program just terminates. All I have in the code is just an if-else statement that returns true or false. Why don't I see anything on the console? I am using Eclipse Juno's Console by the way.

• writing terminal output to file

  - by user1551817

  On my machine, I have some software which takes commands in the terminal and returns a list of values. To run it, I have to type something like: pdv -t filename I am trying to run it as part of a python programme. When I run the following: os.system('pdv -t %s' % (epoch_name)) then I get the values that I desire returned to my terminal (where epoch_name is the variable name for the filename). But when I try to write the result to a file: os.system('pdv -t %s % "(epoch_name)" > 123.txt') the file 123.txt is produced but it is empty. I know that I am misplacing the " and/or ' characters, but I can't figure out where they should go. Any help would be gratefully received!

• any other way to find char array length?

  public static int getLenth(char[] t) { int i=0; int count=0; try { while(t[i]!='\0') { ++count; i++; } return count; } catch(ArrayIndexOutOfBoundsException aiobe) { return count; } } This method returns length of charArray. But my question is, is there is some other "ways" to find the length of charArray without using this try, catch statements & all ?? Thanks in advance :)
