  • cannot print popup displaying pdf file

    - by user369544
    I have a php file with the following code: <?php ?> <form action="" id="f1" name="f1"> <input type="button" name="preview" value="Open PDF" onclick="showPDF()" /> </form> <script type="text/javascript" src="jquery-1.4.2.min.js"></script> <script type="text/javascript"> function showPDF(){ var newwin=window.open("pdf.pdf","Window1","menubar=no,width=430,height=360,toolbar=no"); newwin.print(); } </script> It opens up a popup window with pdf file inside it BUT fails to open the print dialog box. But the same code without the pdf filename i.e var newwin=window.open("","Window1","menubar=no,width=430,height=360,toolbar=no"); opens up the popup window and show the print dialog box. Can anybody provide me a solution to this

  • getElementsByTagName() equivalent for textNodes

    - by levik
    Is there any way to get the collection of all textNode objects within a document? getElementsByTagName() works great for Elements, but textNodes are not Elements. Update: I realize this can be accomplished by walking the DOM - as many below suggest. I know how to write a DOM-walker function that looks at every node in the document. I was hoping there was some browser-native way to do it. After all it's a little strange that I can get all the <input>s with a single built-in call, but not all textNodes.

    I would like to have input field that users can enter custom text value or choose from drop down, normal select only offers drop down options.

  • In Python, are there builtin functions for elementwise map of boolean operators over tuples of lists

    - by bshanks
    For example, if you have n lists of bools of the same length, then elementwise boolean AND should return another list of that length that has True in those positions where all the input lists have True, and False everywhere else. It's pretty easy to write, i just would prefer to use a builtin if one exists (for the sake of standardization/readability). Here's an implementation of elementwise AND: def eAnd(*args): return [all(tuple) for tuple in zip(*args)] example usage: >>> eAnd([True, False, True, False, True], [True, True, False, False, True], [True, True, False, False, True]) [True, False, False, False, True] thx

  • Updating display of elements on the web page without refreshing the whole page

    - by ivorossi3
    Last time I coded a web application was almost 10 years ago. I used Java/JSP/HTML/CSS etc. I've been coding non-web applications only ever since. When I look at modern sites now (like this one), I realize how my web development skills are obsolete. Maybe the most obvious "feature" that I wouldn't know how to implement now is the update of elements on the page after user input without having to refresh the whole page (e.g. the voting/downvoting here updates the vote count without reloading the whole page). What are the basic technologies behind this?

  • mysql inserts & updates optimized

    - by user271619
    This is an optimization question, mostly. I have many forms on my sites that do simple Inserts and Updates. (Nothing complicated) But, several of the form's input fields are not necessary and may be left empty. (again, nothing complicated) However, my SQL query will have all columns in the Statement. My question, is it best to optimize the Inserts/Update queries appropriately? And only apply the columns that are changed into the query? We all hear that we shouldn't use the "SELECT *" query, unless it's absolutely needed for displaying all columns. But what about Inserts & Updates? Hope this makes sense. I'm sure any amount of optimization is acceptable. But I never really hear about this, specifically, from anyone.

  • Drupal Navigation Conundrum

    - by Vecta
    I'm attempting to set up navigation withing a Drupal site and am having a bit of trouble. I'm trying to have a series of pages that each have a set number of sub-pages. These pages will need to link to one another. All pages will contain similar content. For instance: Page 1 will have sub-pages a, b, c, d, e, and f all with content related to the topic of page 1 Page 2 will have sub-pages a, b, c, d, e, and f with content related to the topic of page 2 I'd like these links to appear in a horizontal nav bar on each page. Is it possible to accomplish this using the book module? I've also read some information about the taxonomy menu module that sounds promising, but I'm not really sure how that would work. What route should I look into? Thanks for any input!

  • Javascript & jquery : Unable to increment within a form

    - by Daniyal
    I got a simple increment function like this: $(function(){ $("#inc").click(function(){ var value = parseInt($(":text[name='ice_id']").val()) + 1; $(":text[name='ice_id']").val(value); }); $("#dec").click(function(){ var value = parseInt($(":text[name='ice_id']").val()) - 1; $(":text[name='ice_id']").val(value); }); }); the ice_id text field is embedded within a form <form id="masterSubmit" name="masterSubmit" action="" method="post"> <td><input id="ice_id" type="text" name="ice_id" size="16" maxlength="15"></td> </form> When I try now to increment , it successfully increments a number, but shows the following weird behavior: It 'refreshes' the site, so that the content of the text field is gone. This behavior disappears, if I comment out the form tags ...unfortunately the form tags are required for an AJAX-submit. Are there any ways to avoid this problem? Thanks in advance for any hints and best regards Daniyal

  • Which method should I use to give the perception the computer is thinking in programming?

    - by Roy
    I want to create a simple game like tic tac toe where the human user is playing against the computer. The computer function takes a couple of milliseconds to run but I would like to make the computer take 5 seconds to make a move. Which method should I use? 1) Create two memory threads. One for the computer and one for the human user. When the computer is taking 5 seconds to imitate thinking, the human user thread is paused for 5 seconds. 2) Disable input devices for 5 seconds using timer or dispatchertimer 3) Any better methods you can think of Thanks!

  • IIS 7 problem which does not occur under apache

    - by cc0
    I'm hosting a little site using a JavaScript to draw a simple graph. It involves one html index file, some css and some js files. It has all been working perfectly on two different apache servers, but when I set up IIS 7 the ajax calls fail. I get no java debug errors in firefox that I can work with, or any kind of error message at all. Without going into the code itself, does anyone have a similar experience with IIS? This is the first time I'm using IIS so I'm not quite sure what to expect to have trouble with. I'd love some input on this, if I have to delve into the code itself I'll make a new thread, I just thought I'd see if this could be a typical issue. Any help is appreciated!

  • implementing keepalives with Java

    - by Bilal
    Hi All, I am biulding a client-server application where I have to implement a keepalive mechanism in order to detect that the client has crashed or not. I have separate threads on both client and server side. the client thread sends a "ping" then sleeps for 3 seconds, while the server reads the BufferedInput Stream and checks whether ping is received, if so it makes the ping counter eqauls zero, else it increments the counter by +1, the server thread then sleeps for 3 seconds, if the ping counter reaches 3, it daclares the client as dead. The problem is that when the server reads the input stream, its a blocking call, and it blocks untill the next ping is received, irrespective of how delayed it is, so the server never detects a missed ping. any suggestions, so that I can read the current value of the stream and it doesn't block if there is nothing on the incoming stream. Thanks,

  • IRepository with Inherited Classes

    - by Stacey
    In keeping with the Repository pattern of data input, I've a question in regards to using inherited classes. For instance, suppose I would have the class... class Employee IEmployeeRepository { Add(Employee employee); } This works fine, nothing wrong with it so far... but now let's say I continue on.. class Manager : Employee Okay, now let's assume that I never need to enter a manager different than an Employee? What's the best approach here? Would a scenario such as .. IEmployeeRepository { Add<T>(T employee) where T : Employee } Be the best approach, or do I need to abstract a different repository for each type?

  • Why is $file empty in custom symfony file validator?

    - by codecowboy
    I am setting a custom file validator for a file input field in Symfony 1.4 (Doctrine) $this-setValidator('filename', new sfValidatorFile(array( 'mime_types' = 'web_images', 'path' = sfConfig::get('sf_upload_dir').'/animals', 'validated_file_class' = 'CustomValidatedFile', 'required' =false ))); I then want to override the save method to generate some thumbnails: class CustomValidatedFile extends sfValidatedFile { private $savedFilename; // Override sfValidatedFile's save method public function save($file = null, $fileMode = 0666, $create = true, $dirMode = 0777) { $this-savedFilename = $this-generateFilename(); // This makes sure we use only one savedFilename (it will be the first) if ($this-savedFilename === null ) { $this-savedFilename = $file; } $thumbnail = new sfThumbnail(150,150); $thumbnail-loadFile($this-getTempName()); $thumbnail-save(sfConfig::get('sf_upload_dir').'/thumbnails/thumb_'.$this-savedFilename); // Let the original save method do its magic :) return parent::save($this->savedFilename, $fileMode, $create, $dirMode); } } This fails with the error "The file "" is not readable." This is coming from sfThumbnailPlugin because the value of $file is null. My question is why is $file null?

  • When will YOU adopt C++0x?

    - by HighCommander4
    I'm particularly looking for input from managers of ongoing C++ projects: Have you already adopted C++0x? If so, what has your experience been like? If you haven't adopted C++0x yet, are you planning to? If so, what is your timeline (in rough terms)? Are there any obstacles that are holding you back from adopting C++0x? Perhaps you are waiting for your favourite compiler or IDE to catch up? For managers of open source projects: are you afraid that adopting C++0x will mean less developers who are willing/able to contribute because they don't know the new features? Or, on the other hand, do you think most developers have been eagerly awaiting C++0x, and and will jump at the opportunity to use it? Do you think C++0x is stable enough to be adopted by a large project?

  • How to persist and load an object which conforms to NSCoding protocol?

    - by mystify
    I have made an class which conforms to the NSCoding protocol and does all the encode and decode stuff. For my app, I simply want to persist an object from that class to the device and the next time when the app launches, I want to load that object back into memory. Basically it's just an class which holds some user input information. For example the user starts writing a text but then quits the app. Next time I want to load that data object. I guess I need NSKeyedArchiver? Is there a good tutorial on this? How do I do that?

  • How to capture the value change of numericUpDown ctrl real-time in .NET?

    - by Carlos_Liu
    I have implement the ValueChanged event, but I found it will be triggered only after change the focus from numericUpDown to other control or by clicking the up/down arrow. Inputting the value in the control will not trigger ValueChanged event. What I did now is adding an KeyDown event and judge if the input value is numeric (can not include SHIFT/CTRL/ALT key); but there is another case need to be involved: the user can paste value into the numericUpDown ctrl What I need is : When I was typing numeric value (only numeric) in the numericUpDown ctrl, it will known the content has been changed; When pasted a numeric value into the ctrl, it also kowns the content changed

  • Check if a MediaWiki page exists (Python)

    - by compie
    I'm working on a Python script that transforms this: foo bar Into this: [[Component foo]] [[bar]] The script checks (per input line) if the page "Component foo" exists. If it exists then a link to that page is created, if it doesn't exist then a direct link is created. The problem is that I need a quick & cheap way to check if a lot of wiki pages exist.I don't want to (try to) download all the 'Component' pages. I already figured out a fast way to do this by hand: Edit a new wiki page. paste all the 'component' links into the page, press preview, and then save the resulting preview HTML page. The resulting HTML file contains a different link for existing pages than for non-existing pages. So to rephrase my question: How can I save a mediawiki preview page in Python?

  • Jquery counting elements by class what is the best way to implement this?

    - by 133794m3r
    Ok what i'm trying to do is to count all of the elements in the current page with the same class and then i'm going to use it to be added onto a name for a input form. Basically i'm allowing users to click on an and then by doing so add another one for more of the same type of items. But i can't think of a way to count all of these simply with jquery/javascript. I was going to then name the item as something like name="whatever(total+1)", if anyone has a simple way to do this i'd be extremely grateful as javascript isn't exactly my native tongue and stack overflow usually has a ton of great answers and a great community so i'm hoping my query will not go unheard.

  • How to sub with matched groups and variables in Python

    - by Syed
    Hi, new to python. This is probably simple but I haven't found an answer. rndStr = "20101215" rndStr2 = "20101216" str = "Looking at dates between 20110316 and 20110317" outstr = re.sub("(.+)([0-9]{8})(.+)([0-9]{8})",r'\1'+rndStr+r'\2'+rndStr2,str) The output I'm looking for is: Looking at dates between 20101215 and 20101216 But instead I get: P101215101216 The values of the two rndStr's doesn't really matter. Assume its random or taken from user input (I put static vals here to keep it simple). Thanks for any help.

  • Using pow() for large number

    - by g4ur4v
    I am trying to solve a problem, a part of which requires me to calculate (2^n)%1000000007 , where n<=10^9. But my following code gives me output "0" even for input like n=99. Is there anyway other than having a loop which multilplies the output by 2 every time and finding the modulo every time (this is not I am looking for as this will be very slow for large numbers). #include<stdio.h> #include<math.h> #include<iostream> using namespace std; int main() { unsigned long long gaps,total; while(1) { cin>>gaps; total=(unsigned long long)powf(2,gaps)%1000000007; cout<<total<<endl; } }
