• JQuery QuickSearch: Searching on load if the input isn't blank

  - by ckm-88

  I have used the jquery quicksearch plugin and it works fine, except for one problem. I would like the quicksearch to run when the page is loaded. I have created a second quicksearch function (which is called when the page is loaded) and changed the bind to something else, but it won't work on "load" or "ready". If I change the bind to "focus" and put the focus onto the textfield it works, but only in IE. The reason I want to do this is because there is a "view" link where the user leaves the page. When they come back, I would like the search results to be as they left them.

• Validate NSString

  - by Chris

  I am validating an NSString to ensure that the string does not contain apostrophes. The code I'm using to do this is NSCharacterSet * invalidNumberSet = [NSCharacterSet characterSetWithCharactersInString:@"'"]; NSScanner * scanner = [NSScanner scannerWithString:string]; NSString * scannerResult; [scanner setCharactersToBeSkipped:nil]; [scanner scanUpToCharactersFromSet:invalidNumberSet intoString:&scannerResult]; if(![string isEqualToString:scannerResult]) { return 2; } Returning 2 represents an error. This code works, except for the case where the string is an apostrophe. To get around this issue, I added the following code above the preceding block. if([string isEqualToString:@"'"]); { return 2; } This code is evaluating to true, regardless of the input. I need to either prevent the first block from crashing with the input of ', or get the second block to work. What am I missing?

• How to display a border-bottom only if table cells are not empty (CSS)

  - by Polarpro

  Hey there, I've got a Filemaker calculation that generates an HTML page with several tables. If the calculation results in values for certain fields the result would be <table> <tr><td>Example value 1</td></tr> <tr><td>Example value 2</td></tr> ... </table> If the calculation finds no values to be displayed, the result would simply be <table> </table> In the first case, I want to the table to display a border at the bottom (or any other horizontal line); in the second case, I don't want to display a border at the bottom. I cannot find a way to get this done using a CSS... Thanks in adavance :-)

• Should I create a new window or modify the old one?

  - by Roman

  I am programming a GUI application in Java. I do it for the first time. I would like to have a form (with radio buttons and so on). After the form is filled in and the "Submit" button is pressed I would like to have a new window. I see two potential ways to do it: Close the "old" window and open a "new" one. Remove "old" elements from the existing window and put there "new" elements. What is the standard way to go? If it is the first way, what is the command to close the window? If it is the second one, how can I remove elements from the existing window?

• Can I un-assign (clear) all fields of an instance?

  - by Roman

  Is there a simple way to clear all fields of an instance from a an instance? I mean, I would like to remove all values assigned to the fields of an instance. ADDED From the main thread I start a window and another thread which controls state of the window (the last thread, for example, display certain panels for a certain period of time). I have a class which contains state of the window (on which stage the user is, which buttons he already clicked). In the end, user may want to start the whole process from the beginning (it is a game). So, I decided. So, if everything is executed from the beginning, I would like to have all parameter to be clean (fresh, unassigned). ADDED The main thread, creates the new object which is executed in a new thread (and the old thread is finished). So, I cannot create a new object from the old thread. I just have a loop in the second thread.

• writing a single line of a file in C++ into two different arrays

  - by mekasperasky

  suppose a text file has 11001100 11001101 and i open the text file and take the input from the file as pt[0]=11001100, pt[1]=11001101.. but if i take the input from file as inpt it wont put it in two different arrays which is obvious but it takes the whole line . Thus I have to take another for loop and traverse through the whole string and when I find a null character i start putting into the second array . But how can I do it without putting it into a variable and traversing .. I mean directly from the file itself ..

• Dereferencing confusion? What is this example here called?

  - by perf

  Considering this PHP example: class A { public function getB( ) { return new B(); } } class B { public function test( ) { echo "Hello"; } } I could use this: $a = new A( ); $b = $a->getB( ); $b->test( ); // Hello Or this: $a = new A(); $a->getB( )->test( ); // Hello Taking a closer look at the second example... What is the name of this form of expression? Does this have something to do with dereferencing? In which programming languages is this available? What other forms of this exist?

• PHP Losing variable data

  - by Conor B

  Hi, I'm having an issue with PHP losing data in a variable. There is quite a bit of data in the variable, because it basically contains a binary file, but I'm wondering if this is cause for it to completely lose it's information. Looking at a snippet from my code which is used to deal with email attachments: var_dump($data) if (array_key_exists('filename', $params) || array_key_exists('name', $params)) { var_dump($data) ... } The first var_dump gives the desired output of the file: "string(283155) " --Apple-Mail-5-930065543 ... etc while the second gives an output of: string(0) "" ... string(0) "" Any idea why this is happening? Does PHP just drop data in variables if they are really large? (I didn't think so, as I've never had this problem before) If so, any workaround? Thanks!

• Clojure: find repetition

  - by demi

  Let we have a list of integers: 1, 2, 5, 13, 6, 5, 7 and I want to find the first number has a duplicate before it and return a vector of two indices, In my sample, it's 5 at [2, 5]. What I did so far is loop, but can I do it more elegant, short way? (defn get-cycle [xs] (loop [[x & xs_rest] xs, indices {}, i 0] (if (nil? x) [0 i] ; Sequence is over before we found a duplicate. (if-let [x_index (indices x)] [x_index i] (recur xs_rest (assoc indices x i) (inc i)))))) No need to return number itself, because I can get it by index and, second, it may be not always there.

• Use of Shl in assembly

  - by user3097712

  I have the following piece of lines and I do not understand that. Hope that someone can help me: ..... MOV EAX, DWORD PTR SS:[EBP-0x4] SHL EAX, 0x2 ADD EAX, DWORD PTR SS:[EBP-0x8] PUSH EAX .... Normally, it helps me to translate that into C language. But somehow I cant find a way to do it in that case. So, I only know that in the second line with SHL the register is multiplied by 4. And that the DWORD PTR SS:[EBP-0x4] looks like an array representation but i am not sure. I also find the following link x86 Assembler: shl and other instructions But I dont understand the answer there. So my question would be: What it is going on there? Thx...

• IE8 $('body').width() is 0 on $(window).load()

  - by allicarn

  On $(document).ready I run through a for loop twice and alert out the body's width ($('body').width();) each time through. I get a value I would expect (ex. 1092). On $(window).load I run through another for loop twice, also alerting out the body's width each time through. I get 0 the first time through (and the page looks completely blank behind the alert), and then a value I would expect the second time through (ex. 1092). This is an issue I am not able to replicate in a stripped-down example, nor any other browser (Chrome, Safari, Firefox, IE9, IE10). Does anyone have any ideas, or other things that I could test for? I am using $(window).load to cut up some divs based on their width, which is based on their font size, which is based on a webfont (which isn't necessarily loaded by the time $(document).ready fires).

• (Python) Extracting Text from Source Code?

  - by zhuyxn

  Currently have a large webpage whose source code is ~200,000 lines of almost all (if not all) HTML. More specifically, it is a webpage whose content is a few thousand blocks of paragraphs separated by line breaks (though a line break does not specifically mean there is a separation in content) My main objective is to extract text from the source code as if I were copying/pasting the webpage into a text editor. There is another parsing function I would like to use, which originally took in copied/pasted text rather than the source code. To do this, I'm currently using urllib2, and calling .get_text() in Beautiful Soup. The problem is, Beautiful Soup is leaving tremendous amounts of white space in my code, and it is difficult to pass the result into the second "text" parser. I have done quite a bit of research on parsing HTMLs, but I'm frankly not sure how to solve this problem easily. Furthermore, I'm a bit confused on how to use imports like lxml to extract text as if I were to simply copy and paste?

• 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

• iOS Display Different Image on Click

  - by user1506841

  Using XCode, I am trying to figure out how to display a different image when someone clicks or presses down on one of my buttons before being taken to a second screen. For example, I have a contact icon on my home screen. When a user clicks the icon, it should change to a darker version on tap before going to the contact screen. Any help is appreciated. -(IBAction) ButtonPressed :(id)sender { UIButton *tempButton = (UIButton *) sender; int tag = tempButton.tag; NSString *viewName; switch (tag) { case 1: [FlurryAnalytics logEvent:@"Contact-Screen"]; viewName = @"ContactScreen"; if( self.appDelegate.sound) [Click play]; [self.appDelegate moveToView:viewName]; break; } }

• 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 do dicts of defaultdict(int)'s use so much memory? (and other simple python performance question

  - by dukhat

  import numpy as num from collections import defaultdict topKeys = range(16384) keys = range(8192) table = dict((k,defaultdict(int)) for k in topKeys) dat = num.zeros((16384,8192), dtype="int32") print "looping begins" #how much memory should this use? I think it shouldn't use more that a few #times the memory required to hold (16384*8192) int32's (512 mb), but #it uses 11 GB! for k in topKeys: for j in keys: dat[k,j] = table[k][j] print "done" What is going on here? Furthermore, this similar script takes eons to run compared to the first one, and also uses an absurd quantity of memory. topKeys = range(16384) keys = range(8192) table = [(j,0) for k in topKeys for j in keys] I guess python ints might be 64 bit ints, which would account for some of this, but do these relatively natural and simple constructions really produce such a massive overhead? I guess these scripts show that they do, so my question is: what exactly is causing the high memory usage in the first script and the long runtime and high memory usage of the second script and is there any way to avoid these costs?

• Quick C Style Question

  Which is considered better style? int set_int(int *source){ *source = 5; return 0; } int main(){ int x*; set_int(x); } OR int *set_int(){ int *temp = NULL; temp = malloc(sizeof (int)); *temp = 5; return temp; } int main(){ int *x = set_int(); } Coming for a higher level programming background I gotta say I like the second version more. Any, tips would be very helpful. Still learning C.

• JQuery fadeIn, fadeOut div

This is my code $(document).ready(function(){ $('#login_button').click(function(e){ $('#login_cont').fadeIn(); }); $(document).click(function(e){ $('#login_cont').fadeOut(); }); }); This looks good to me (I'm new at this). But. Every time I click on the button, the div appears but then also disappears in less than a second... why and how can I fix it?

• Picking encryption cipher for mcrypt

  - by Autolycus

  I have few questions about this code: <?php $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB); $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND); $key = "This is a very secret key"; $text = file_get_contents('path/to/your/file'); echo strlen($text) . "\n"; $crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $text, MCRYPT_MODE_ECB, $iv); file_put_contents('path/to/your/file', $crypttext); ?> It encrypts the file just fine, however it adds additional nulls at the end, so if I encrypt: a test string is this one and here is a new line once decrypted becomes: a test string is this one and here is a new line 000000000000000 What's going on? Second, is MCRYPT_RIJNDAEL_256 compatible with AES-128? Finally, how would I let another party decrypt a file I've encrypted? They would need to know which encryption was used and I am not sure what to tell them.
