  • jQuery: Self Executing Plugin?

    - by GnrlBzik
    I am working on expansion of my jQuery plug-in authoring knowledge, just playing around with my own ideas for learning benefits. So i was wondering how you guys tackle the need of plugin executing without any user specific input. So I have a need for plug-in that executes right away after document is ready, without any user's specific input just as long as doc is loaded, so the only way I see how to execute plug-in on it's own is to attach handler to ready listener that executes my function which I extended the jQuery with. And because this needs to be self enclosed, part of the code, I attach handler to event listener within the function. So how else could one tackle this? Any take at this is appreciated. Thank you in advance everyone.

  • How can a hacker put a file on my server root (apache, php, 1and1)

    - by mike-sav
    Hi there, I have a site hosted on 1and1 and a couple of weeks ago I noticed a hacker had put a .php file on the server that when viewed in a browser exposed my DB schema, DB connection strings, FTP account (for file uploads using a form), etc, etc. Naturally I panicked and I wiped the server and reuploaded my files. Fortunatley I encrypt passwords using MD5 and I don't store things like credit card details, etc, etc. Now I checked my files and with all user input I use a clean function (htmlentities, sql_real_escape_string, etc, etc) that strips the input of any XSS or SQL injection. I have also made sure that the session key gets re-engineered when a user status changes (like they log into their account) to prevent session hijacking, my folder permissions are set to 755 and file permission are 644. Has anyone got any idea how this could have happened? Or if I'm missing something

    - by AtomR
    <input src="LOGO.JPG" type="image" name="imagem"> I have an xml element that contains the image path that needs to be displayed in HTML after the parse. <xsl:value-of select="image"/> returns the string that is stored in the image element but how can I use it to make that string be the src atribute value in an html tag? I tried <input src="<xsl:value-of select="image"/>" type="image" name="imagem"> but obviously that doesn't work so how can it be done? I hope I was clear in my question. Please help!

  • Optional read from STDIN in C

    - by Yuval A
    My application is basically a shell which expects an input of type cmd [x], where cmd is constant and x is optional. So cmd 1 is legal as well as cmd by itself - then I assume a default parameter for x. I am doing this: char cmd[64]; scanf("%s", cmd); int arg; scanf("%d", &arg); // but this should be optional How can I read the integer parameter, and set it to a default if none is currently available in the prompt? I do not want the prompt to wait for additional input if it was not given in the original command. I tried several versions using fgetc() and getchar() and comparing them to EOF but to no avail. Each version I tried ends up waiting on that optional integer parameter.

  • python - checking if a user has admin privileges

    - by Matt
    Hi, I'm writing a little program as a self-learning project in Python 3.x. my idea is for the program to allow two fields of text entry to the user, and then plug the user's input into the value of two specific registry keys. What I was wondering, and something my books don't seem to cover, is if there is a simple way to make it check if the current user can access the registry. I'd rather it cleanly tell the user that he needs admin privileges than for the program to go nuts and crash because it's trying to access a restricted area. I'd like it to make this check as soon as the program launches, before the user is given any input options. What code is needed for this? thanks for the help

  • Attaching javascript events to form widgets

    - by user334017
    I have a form with a drop down menu and I want to do a javascript action whenever the user changes the selection. I imagine it is possible find the input later, using javascript, and attach an event to to it; but it seems like it would be easier if there was some sort of attribute or option that could be defined in form-configure(): e.g. $this->widgetSchema['menu'] = new sfWidgetFormChoice(array( ... 'onclick' => javascript function )); obviously this doesn't work, and it probably wouldn't be an onclick method either, but my question is how do you attach a javascript event to a input/widget?

  • Reading HttpURLConnection InputStream - manual buffer or BufferedInputStream?

    - by stormin986
    When reading the InputStream of an HttpURLConnection, is there any reason to use one of the following over the other? I've seen both used in examples. Manual Buffer: while ((length = inputStream.read(buffer)) > 0) { os.write(buf, 0, ret); } BufferedInputStream is = http.getInputStream(); bis = new BufferedInputStream(is); ByteArrayBuffer baf = new ByteArrayBuffer(50); int current = 0; while ((current = bis.read()) != -1) { baf.append(current); } EDIT I'm still new to HTTP in general but one consideration that comes to mind is that if I am using a persistent HTTP connection, I can't just read until the input stream is empty right? In that case, wouldn't I need to read the message length and just read the input stream for that length? And similarly, if NOT using a persistent connection, is the code I included 100% good to go in terms of reading the stream properly?

  • o write a C++ program to encrypt and decrypt certain codes.

    - by Amber
    Step 1: Write a function int GetText(char[],int); which fills a character array from a requested file. That is, the function should prompt the user to input the filename, and then read up to the number of characters given as the second argument, terminating when the number has been reached or when the end of file is encountered. The file should then be closed. The number of characters placed in the array is then returned as the value of the function. Every character in the file should be transferred to the array. Whitespace should not be removed. When testing, assume that no more than 5000 characters will be read. The function should be placed in a file called coding.cpp while the main will be in ass5.cpp. To enable the prototypes to be accessible, the file coding.h contains the prototypes for all the functions that are to be written in coding.cpp for this assignment. (You may write other functions. If they are called from any of the functions in coding.h, they must appear in coding.cpp where their prototypes should also appear. Do not alter coding.h. Any other functions written for this assignment should be placed, along with their prototypes, with the main function.) Step 2: Write a function int SimplifyText(char[],int); which simplifies the text in the first argument, an array containing the number of characters as given in the second argument, by converting all alphabetic characters to lower case, removing all non-alpha characters, and replacing multiple whitespace by one blank. Any leading whitespace at the beginning of the array should be removed completely. The resulting number of characters should be returned as the value of the function. Note that another array cannot appear in the function (as the file does not contain one). For example, if the array contained the 29 characters "The 39 Steps" by John Buchan (with the " appearing in the array), the simplified text would be the steps by john buchan of length 24. The array should not contain a null character at the end. Step 3: Using the file test.txt, test your program so far. You will need to write a function void PrintText(const char[],int,int); that prints out the contents of the array, whose length is the second argument, breaking the lines to exactly the number of characters in the third argument. Be warned that, if the array contains newlines (as it would when read from a file), lines will be broken earlier than the specified length. Step 4: Write a function void Caesar(const char[],int,char[],int); which takes the first argument array, with length given by the second argument and codes it into the third argument array, using the shift given in the fourth argument. The shift must be performed cyclicly and must also be able to handle negative shifts. Shifts exceeding 26 can be reduced by modulo arithmetic. (Is C++'s modulo operations on negative numbers a problem here?) Demonstrate that the test file, as simplified, can be coded and decoded using a given shift by listing the original input text, the simplified text (indicating the new length), the coded text and finally the decoded text. Step 5: The permutation cypher does not limit the character substitution to just a shift. In fact, each of the 26 characters is coded to one of the others in an arbitrary way. So, for example, a might become f, b become q, c become d, but a letter never remains the same. How the letters are rearranged can be specified using a seed to the random number generator. The code can then be decoded, if the decoder has the same random number generator and knows the seed. Write the function void Permute(const char[],int,char[],unsigned long); with the same first three arguments as Caesar above, with the fourth argument being the seed. The function will have to make up a permutation table as follows: To find what a is coded as, generate a random number from 1 to 25. Add that to a to get the coded letter. Mark that letter as used. For b, generate 1 to 24, then step that many letters after b, ignoring the used letter if encountered. For c, generate 1 to 23, ignoring a or b's codes if encountered. Wrap around at z. Here's an example, for only the 6 letters a, b, c, d, e, f. For the letter a, generate, from 1-5, a 2. Then a - c. c is marked as used. For the letter b, generate, from 1-4, a 3. So count 3 from b, skipping c (since it is marked as used) yielding the coding of b - f. Mark f as used. For c, generate, from 1-3, a 3. So count 3 from c, skipping f, giving a. Note the wrap at the last letter back to the first. And so on, yielding a - c b - f c - a d - b (it got a 2) e - d f - e Thus, for a given seed, a translation table is required. To decode a piece of text, we need the table generated to be re-arranged so that the right hand column is in order. In fact you can just store the table in the reverse way (e.g., if a gets encoded to c, put a opposite c is the table). Write a function called void DePermute(const char[],int,char[], unsigned long); to reverse the permutation cypher. Again, test your functions using the test file. At this point, any main program used to test these functions will not be required as part of the assignment. The remainder of the assignment uses some of these functions, and needs its own main function. When submitted, all the above functions will be tested by the marker's own main function. Step 6: If the seed number is unknown, decoding is difficult. Write a main program which: (i) reads in a piece of text using GetText; (ii) simplifies the text using SimplifyText; (iii) prints the text using PrintText; (iv) requests two letters to swap. If we think 'a' in the text should be 'q' we would type aq as input. The text would be modified by swapping the a's and q's, and the text reprinted. Repeat this last step until the user considers the text is decoded, when the input of the same letter twice (requesting a letter to be swapped with itself) terminates the program. Step 7: If we have a large enough sample of coded text, we can use knowledge of English to aid in finding the permutation. The first clue is in the frequency of occurrence of each letter. Write a function void LetterFreq(const char[],int,freq[]); which takes the piece of text given as the first two arguments (same as above) and returns in the 26 long array of structs (the third argument), the table of the frequency of the 26 letters. This frequency table should be in decreasing order of popularity. A simple Selection Sort will suffice. (This will be described in lectures.) When printed, this summary would look something like v x r s z j p t n c l h u o i b w d g e a q y k f m 168106 68 66 59 54 48 45 44 35 26 24 22 20 20 20 17 13 12 12 4 4 1 0 0 0 The formatting will require the use of input/output manipulators. See the header file for the definition of the struct called freq. Modify the program so that, before each swap is requested, the current frequency of the letters is printed. This does not require further calls to LetterFreq, however. You may use the traditional order of regular letter frequencies (E T A I O N S H R D L U) as a guide when deciding what characters to exchange. Step 8: The decoding process can be made more difficult if blank is also coded. That is, consider the alphabet to be 27 letters. Rewrite LetterFreq and your main program to handle blank as another character to code. In the above frequency order, space usually comes first.

  • A Simulator for a non-deterministic Push-Down Automaton

    - by shake
    Well, i need to make simulator for non-deterministic Push-Down Automaton. Everything is okey, i know i need to do recursion or something similar. But i do not know how to make that function which would simulate automaton. I got everything else under control, automaton generator, stack ... I am doing it in java, so this is maybe only issue that man can bump on, and i did it. So if anyone have done something similar, i could use advices. This is my current organisation of code: C lasses: class transit: list -contains non deterministic transitions state input sign stack sign class generator it generate automaton from file clas NPA public boolean start() - this function i am having trouble with Of course problem of separate stacks, and input for every branch. I tried to solve it with collection of objects NPA and try to start every object, but it doesn work :((..

I need to save data in minutes but User have privilege to choose will his input be in minutes, days or hours. So i have to do if loop. I now how if loop works but i don't know how to wite it in grails. I was thinking something like this: n=1 if(params.type=Dani){ n= 3600 }else if(params.type=Sati) { n=60 } def minute=params.minute*n but how to call that choosen input "Dani"? I can't write Params.type=Dani. Does if loop go in controller in my case?

  • Is hierarchical product backlog a good idea in TFS 2012-2013?

    - by Matías Fidemraizer
    I'd like to validate I'm not in the wrong way. My team project is using Visual Studio Scrum 2.x. Since each area/product has a lot of kind of requirements (security, user interface, HTTP/REST services...), I tried to manage this creating "parent backlogs" which are "open forever" and they contain generic requirements. Those parent backlogs have other "open forever" backlogs, and/or sprint backlogs. For example: HTTP/REST Services (forever) ___ Profiles API (forever) ________ POST profile (forever) _______________ We need a basic HTTP/REST profiles' API to register new user profiles (sprint backlog) Is it the right way of organizing the product backlog? Note: I know there're different points of view and that would be right for some and wrong for others. I'm looking for validation about if this is a possible good practice on TFS with Visual Studio Scrum.

  • calculating a gps coordinate given a point, bearing and distance

    - by user530509
    Hello, I have a problem which draws my back in some project for some time now.

But if you follow this path in trying to implement rich interactive behavior, it doesn't take long before you realize that you are creating a Big Ball Of Mud. So what is the path towards expertise in programming the interaction layer? What books, tutorials, exercises, and processes contribute towards the ability to program robust, maintainable JavaScript? We all know that practice is important in any endeavor, but I'm looking for a path similar to the answer here: http://stackoverflow.com/questions/2573135/

  • Flex: convert VideoPlayer.currentTime to string "00:00:00:000"

    - by numediaweb
    Hi there! what about this one: I want to format the currentTime displayed by a videoPlayer component inside flex, something like : 8230.999 to something like 01:59:59:999 which is "hours:minutes:seconds:milliseconds" I trie different sets of codes but they can't get it to work because currentTime is nor a correct miliseconds time as it adds a floating 3 digit point to seconds; so instead of : 2000ms it outputs 2.000 something people like me just can't understand! thanx for any help :) ### UPDATE I still have problem with milliseconds. here's the current MXML: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"> <fx:Script> <![CDATA[ protected function convert_clickHandler(event:MouseEvent):void { var val:Number = new Number(inPut.text); //inPut.text = 1000.001 //val = val * 1000; outPut.text = timeFormat(val); } public static function timeFormat(value:Number):String { var milliseconds:Number = value % 1000; var seconds:Number = Math.floor((value/1000) % 60); var minutes:Number = Math.floor((value/60000) % 60); var hours:Number = Math.floor((value/3600000) % 24); var s_miliseconds:String = (milliseconds<10 ? "00" : (milliseconds<100 ? "0" : ""))+ String(milliseconds); var s_seconds:String = seconds < 10 ? "0" + String(seconds) : String(seconds); var s_minutes:String = minutes < 10 ? "0" + String(minutes) : String(minutes); var s_hours:String = hours < 10 ? "0" + String(hours) : String(hours); return s_hours + ":" + s_minutes + ":" + s_seconds + '.'+s_miliseconds; // returns 00:00:01.000.0009999999999763531 should return 00:00:01.001 // I still have problem with milliseconds } ]]> </fx:Script> <fx:Declarations> <!-- Place non-visual elements (e.g., services, value objects) here --> </fx:Declarations> <s:TextInput x="240" y="72" id="inPut" text="1000.001"/> <s:TextInput x="240" y="140" id="outPut"/> <s:Button x="274" y="107" label="convert" id="convert" click="convert_clickHandler(event)"/> </s:Application>

  • What's wrong with this code? Values not saved to db

    - by Scott B
    Been trying to get this code to work for several days now to no avail. I'm at wits end. I've managed, with the code below, to create a customized category picker widget that appears on the PAGE editor. However, for the life of me, I cannot get the checked categories to save. function my_post_options_box() { if ( function_exists('add_meta_box') ) { //add_meta_box( $id, $title, $callback, $page, $context, $priority ); add_meta_box('categorydiv', __('Page Options'), 'post_categories_meta_box_modified', 'page', 'side', 'core'); } } //adds the custom categories box function post_categories_meta_box_modified($post) { $noindexCat = get_cat_ID('noindex'); $nofollowCat = get_cat_ID('nofollow'); if(in_category("noindex")){ $noindexChecked = " checked='checked'";} else {$noindexChecked = "";} if(in_category("nofollow")){ $nofollowChecked = " checked='checked'";} else {$noindexChecked = "";} ?> <div id="categories-all" class="ui-tabs-panel"> <ul id="categorychecklist" class="list:category categorychecklist form-no-clear"> <li id='category-<?php echo $noindexCat ?>' class="popular-category"><label class="selectit"><input value="<?php echo $noindexCat ?>" type="checkbox" name="post_category[]" id="in-category-<?php echo $noindexCat ?>"<?php echo $noindexChecked ?> /> noindex</label></li> <li id='category-<?php echo $nofollowCat ?>' class="popular-category"><label class="selectit"><input value="<?php echo $noindexCat ?>" type="checkbox" name="post_category[]" id="in-category-<?php echo $nofollowCat ?>"<?php echo $nofollowChecked ?> /> nofollow</label></li> <li id='category-1' class="popular-category"><label class="selectit"><input value="1" type="checkbox" name="post_category[]" id="in-category-1" checked="checked"/> Uncategorized</label></li> </ul> </div> <?php }

  • All Permutations of a string when corresponding characters are not in the same place

    - by r20rock
    I need all possible permutations of a given string such that no character should remain at the same place as in the input string. Eg. : for input "ask" Output: all possible permutaions like "ksa", "kas"... such that 'a' is not in the 1st position , 's' is not in the 2nd positions and so on... in any permutation. I only need the count of such possible permutations I can do this by generating all permutations and filtering them but I need a very efficient way of doing this. All characters in the string are "UNIQUE" Preferred language C++.
