  • Internet Explorer doesn't update file

    - by Leandro
    Hi! I'm using AJAX with PHP to read from a file and update the div's innerHTML. It works on Chrome and Firefox, but not in Internet Explorer. I tried to use: But I think it is useless, since I'm not refreshing the page. if(!$newMsg || $newMsg == "") { // only reading from the file // do nothing } else { $fileData .= "$newMsg"; fwrite($fileHandler, "$newMsg"); } fclose($fileHandler); echo $fileData; Interesting that when it enters the "else" block, it shows the file's content updated. But when it enters the "if" block, it shows the old content.

  • JQuery remove image src prefix

    - by mtwallet
    Hi. I have a bunch of images on a page that are contained within a div with a class of content-block like this: <div class="content-block"> <img src="../images/path/path/image.jpg" alt="blah" title="blah" /> <img src="../images/path/path/image.jpg" alt="blah" title="blah" /> <img src="../images/path/path/image.jpg" alt="blah" title="blah" /> <img src="../images/path/path/image.jpg" alt="blah" title="blah" /> <img src="../images/path/path/image.jpg" alt="blah" title="blah" /> </div> I am loading this html into a div via ajax. When I load it in I need to remove the "../" before the image path, after it loads in so the path remains correct. Can this be done with JQuery? Many thanks in advance.

  • Where Should Using Statements Be Located [closed]

    - by Bobby Ortiz - DotNetBob
    Possible Duplicate: What is the difference between these two declarations? I recently started working on a project with using statement located inside the NameSpace block. namespace MyApp.Web { using System; using System.Web.Security; using System.Web; public class MyClass { I usually put my using statements above the namespace block. using System; using System.Web.Security; using System.Web; namespace MyApp.Web { public class MyClass { I don't think it matters, but I am currious if someone else had a recommendation and could they explain why one way is better than another. Note: I always have one class per file.

  • Icon placement relative to list items

    - by Ronedog
    When I show a hidden div that is stored inside an <li> tag the icons are pushing down to the bottom of the <li>. How can I prevent this? Here's the HTML: <ul> <li>Utah <ul> <li>Park City <ul> <li>Park Cat 1 <div><img class="portf_edit" /></div> <div><img class="portf_archive" /></div> <div><img class="portf_delete" /></div> </li> <li>Skiing <div><img class="portf_edit" /></div> <div><img class="portf_archive" /></div> <div><img class="portf_delete" /></div> </li> </ul> </li> </ul> </li> </ul> Here's the li css: li { list-style-type:none; vertical-align: top; list-style-image: none; left:0px; text-align:left; clear: both; } .portf_edit{ float:right; position: relative; right:50px; display:block; } .portf_archive{ float:right; position: relative; right:-5px; display:block; } .portf_delete{ float:right; position: relative; right: -60px; display:block; } Here's a screen shot prior to expanding which shows the icons how I want them to line up: Here's the screen shot prior to expanding which shows where the icons are being pushed to:

  • Are where any Visual Studio addings for true 'smart tabs'?

    - by Eye of Hell
    Hello. 'Smart Tabs' concept allows to automatically insert tab character for block indentation and space characters for in-block formatting. It's described here. Unfortunately, Visual Studio's 'smart tabs' option in text editor settings just indents text on enter press. Same name, completely different and near useless thing :). So, maybe someone knows of a visual studio addin that can change how 'tab' key work so it will insert tab characters and space characters according to rules mentioned above? Any hints are welcome.

  • How to ignore an exception and continue processing a foreach loop?

    - by Barry Dysert
    I have a test program that is supposed to loop over all the files under C:. It dies when it hits the "Documents and Settings" folder. I'd like to ignore the error and keep looping over the remaining files. The problem is that the exception is thrown in the foreach, so putting a try/catch around the foreach will cause the loop to exit. And putting a try/catch after the foreach never fires (because the exception is thrown in the foreach). Is there any way to ignore the exception and continue processing the loop? Here's the code: static void Main(string[] args) { IEnumerable<string> files = Directory.EnumerateFiles(@"C:\", "*.*", SearchOption.AllDirectories); foreach (string file in files) // Exception occurs when evaluating "file" Console.WriteLine(file); }

  • AudioTrack lag: obtainBuffer timed out

    - by BTR
    I'm playing WAVs on my Android phone by loading the file and feeding the bytes into AudioTrack.write() via the FileInputStream BufferedInputStream DataInputStream method. The audio plays fine and when it is, I can easily adjust sample rate, volume, etc on the fly with nice performance. However, it's taking about two full seconds for a track to start playing. I know AudioTrack has an inescapable delay, but this is ridiculous. Every time I play a track, I get this: 03-13 14:55:57.100: WARN/AudioTrack(3454): obtainBuffer timed out (is the CPU pegged?) 0x2e9348 user=00000960, server=00000000 03-13 14:55:57.340: WARN/AudioFlinger(72): write blocked for 233 msecs, 9 delayed writes, thread 0xba28 I've noticed that the delayed write count increases by one every time I play a track -- even across multiple sessions -- from the time the phone has been turned on. The block time is always 230 - 240ms, which makes sense considering a minimum buffer size of 9600 on this device (9600 / 44100). I've seen this message in countless searches on the Internet, but it usually seems to be related to not playing audio at all or skipping audio. In my case, it's just a delayed start. I'm running all my code in a high priority thread. Here's a truncated-yet-functional version of what I'm doing. This is the thread callback in my playback class. Again, this works (only playing 16-bit, 44.1kHz, stereo files right now), it just takes forever to start and has that obtainBuffer/delayed write message every time. public void run() { // Load file FileInputStream mFileInputStream; try { // mFile is instance of custom file class -- this is correct, // so don't sweat this line mFileInputStream = new FileInputStream(mFile.path()); } catch (FileNotFoundException e) {} BufferedInputStream mBufferedInputStream = new BufferedInputStream(mFileInputStream, mBufferLength); DataInputStream mDataInputStream = new DataInputStream(mBufferedInputStream); // Skip header try { if (mDataInputStream.available() > 44) mDataInputStream.skipBytes(44); } catch (IOException e) {} // Initialize device mAudioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, ConfigManager.SAMPLE_RATE, AudioFormat.CHANNEL_CONFIGURATION_STEREO, AudioFormat.ENCODING_PCM_16BIT, ConfigManager.AUDIO_BUFFER_LENGTH, AudioTrack.MODE_STREAM); mAudioTrack.play(); // Initialize buffer byte[] mByteArray = new byte[mBufferLength]; int mBytesToWrite = 0; int mBytesWritten = 0; // Loop to keep thread running while (mRun) { // This flag is turned on when the user presses "play" while (mPlaying) { try { // Check if data is available if (mDataInputStream.available() > 0) { // Read data from file and write to audio device mBytesToWrite = mDataInputStream.read(mByteArray, 0, mBufferLength); mBytesWritten += mAudioTrack.write(mByteArray, 0, mBytesToWrite); } } catch (IOException e) { } } } } If I can get past the artificially long lag, I can easily deal with the inherit latency by starting my write at a later, predictable position (ie, skip past the minimum buffer length when I start playing a file).

  • Type casting problem with java for-each loop

    - by pharma_joe
    Hi, I have traced an issue with an application I am developing, it is giving me a type cast exception. Funny thing is it is saying it cannot cast "entities.Movie cannot be cast to entities.Movie"?! movies is an ArrayList. try { movies = getMovies(); } catch (Exception e) { e.printStackTrace(System.out); } finally { try { for (Movie movie : movies) { output.append(" <tr>\n"); output.append(" <td>" + movie.getId() + "</td>"); output.append(" </tr>\n"); } } catch (Exception e) { e.printStackTrace(System.out); } }

  • Need help with tweaking a Dropdown with three options, user selects one - a hidden div appears with correct fields

    - by Jack
    Hello Again, I posted a question on here and got an answer within minutes I'm hoping the wizards on here can help me again. Okay so I'm using a script I found online to try and add this function to a shopping cart form. Here's the setup. I have a payment method dropdown with Visa, Mastercard and Bank Withdrawal as the options. For the credit cards I have one hidden div with a certain set of fields, and for the bank I have another hidden div. Each of the divs have named ID's - #payCredit and #payBank The css for both have margin: 0px and display: none; Here's a peice of javascript I used successfuly on a shipping address checkbox `function toggleLayer( whichLayer ) { var elem, vis; if( document.getElementById ) // this is the way the standards work elem = document.getElementById( whichLayer ); else if( document.all ) // this is the way old msie versions work elem = document.all[whichLayer]; else if( document.layers ) // this is the way nn4 works elem = document.layers[whichLayer]; vis = elem.style; // if the style.display value is blank we try to figure it out here if(vis.display==''&&elem.offsetWidth!=undefined&&elem.offsetHeight!=undefined) vis.display = (elem.offsetWidth!=0&&elem.offsetHeight!=0)?'block':'none'; vis.display = (vis.display==''||vis.display=='block')?'none':'block'; }` I was hoping I could change it slightly to meet my needs. Here's the dropdown <label>Payment Method:</label> <select name="payment" id="payment" class="dropdown3" style="width:8em"> <option selected="selected">Select</option> <option value="Visa" onclick="javascript:toggleLayer('payCredit');">Visa</option> <option value="MasterCard" onclick="javascript:toggleLayer('payCredit');">Mastercard</option> <option value="Direct" onclick="javascript:toggleLayer('payBank');">Direct Withdraw</option> </select></li> The current result is that it kinda works. I can open the dropdown and select Visa and it appears, if I select Visa again it disappears, if I select Visa and then select bank, both appear. You can see what i'm working on here - http://test.sharevetcare.com/bestfriends/cart3.html

  • TSQL - create a stored proc inside a transaction statement

    - by Chris L
    I have a sql script that is set to roll to production. I've wrapped the various projects into separate transactions. In each of the transactions we created stored procedures. I'm getting error messages Msg 156, Level 15, State 1, Line 4 Incorrect syntax near the keyword 'procedure'. I created this example script to illustrate Begin Try Begin Transaction -- do a bunch of add/alter tables here -- do a bunch of data manipulation/population here -- create a stored proc create procedure dbo.test as begin select * from some_table end Commit End Try Begin Catch Rollback Declare @Msg nvarchar(max) Select @Msg=Error_Message(); RaisError('Error Occured: %s', 20, 101,@Msg) With Log; End Catch The error seems to imply that I can't create stored procs inside of transaction, but I'm not finding any docs that say otherwise(maybe google isn't being freindly today).

  • Passing Session[] and Request[] to Methods in C#

    - by NYARROW
    In C#, How do you pass the Session[] and Request[] objects to a method? I would like to use a method to parse out Session and Request paramaters for a .aspx page to reduce the size of my Page_Load method. I am passing quite a few variables, and need to support both POSTand GET methods. For most calls, not all variables are present, so I have to test every variable multiple ways, and the code gets long... This is what I am trying to do, but I can't seem to properly identify the Session and Request paramaters (this code will not compile, because the arrays are indexed by number) static string getParam( System.Web.SessionState.HttpSessionState[] Session, System.Web.HttpRequest[] Request, string id) { string rslt = ""; try { rslt = Session[id].ToString(); } catch { try { rslt = Request[id].ToString(); } catch { } } return rslt; } From Page_Load, I want to call this method as follows to retrieve the "MODE" paramater: string rslt; rslt = getParam(Session, Request, "MODE"); Thanks!

  • Exception during processing XSLT transformation!

  • Change find() type of contained model or array transformation

    - by Ramon Marco Navarro
    I have the following model associations: Response->Survey Response->Question Response->Choice Survey->Question Question->Choice I want to create a form where I could answer all the questions for one survey. So I used the following to return the needed data: $questions = $this->Response->Question->find('all', array( 'conditions' => array('survey_id' => $id), 'contain' => array('Choice') ) ); Sample output for debug($questions). Questions Is there a contain() option so that an associated model returns in the find('list') format so that I could use: foreach($question as $questions) { $this-Form-select('field_name', $question['Choice']); } If no option is available, how could I do this using PHP's builting array methods? PS: The foreach block won't turn into a code block. If someone could edit and fix it, please do so and delete this line. Thank you.

  • Remove margin between rows of overflowing inline elements

    - by Ian
    I'm creating a tile-based game and am using block rendering to update a large list of tiles. I'm attempting to do this in the most simple manner, so I've been trying to work with HTML's default layouts. Right now I'm creating 'inline-blocks', omitting whitespace between the elements to avoid horizontal spaces in between them but when the blocks overflow and create a new line there is some vertical margining in which I do not know how to remove. Example to make this a bit clearer: http://jsfiddle.net/mLa93/13/ (Pretty much I just need to remove the spacing between the block rows while retaining the simple markup.)

  • How to read output of android process command

    I am trying to get the output of android shell command 'getprop' with java since getprop() always returns null no matter what. I tried this from developer.android.com: Process process = null; try { process = new ProcessBuilder() .command("/system/bin/getprop", "build.version") .redirectErrorStream(true) .start(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } InputStream in = process.getInputStream(); //String prop = in.toString(); System.out.println(in); process.destroy(); However what is printed is not the output but a bunch of characters and numbers (dont have the exact output right now). How can i get the output of the process? Thanks!

  • Should I use multiple threads in this situation? [Ruby]

    - by mr popo
    I'm opening multiple files and processing them, one line at a time. The files contain tokens separating the data, such that sometimes the processing of one file may have to wait for others to catch up to that same token. I was doing this initially with only one thread and an array indicating with true/false if the file should be read in the current iteration or if it should wait for some of the others to catch up. Would using threads make this simpler? More efficient? Does Ruby have a mechanism for this?

  • Problem with $.get while submitting form

    - by bradenkeith
    I'm trying to verify that an Account Name is not already in use once a user fills out a form. The code looks like: $("#add_account").submit( function () { $.get( "'.url::site("ajax/check_account_name").'", {account_name: "t"}, function(data){ alert( data ); }); }); I get a $.get response if the statement sits like this: $(document).ready( function () { $.get( "'.url::site("ajax/check_account_name").'", {account_name: "t"}, function(data){ alert( data ); }); }); Which leads me to believe that my $.get statement is correct. Is there some jQuery rule I'm not familiar with that would cause this to fail in on submit scenario? In code block 1, I get values returned like they should. Block 2 gives me a blank response. Any ideas? Thanks for your time, I know you have better things to be doing.

When i tried : http://sdrv.ms/1bEsPWz (as the posted sample will not display, i need to show a picture, as i don't have 10 xxx, i can't insert a picture, I am only left with a skydrive reference) In english, the and syntax was tried but it failed to show all content inside the block. It only showed the "is equal to - pre sample " part. I thought - did not care what was inside ? Can some explain how to make a truely literal block display ? I have my reasons why i don't want to have the " syntax in the html. Thanks

  • Animate/Ease an element to position when other elements disappear

    - by Jonathan
    Please take a look at this fiddle: http://jsfiddle.net/dhcyA/ Try clicking on a block. What I want is that when the other elements disapear, the selected block will animate/ease to his giving position instead of just jumping like it does now. Then the same animation repeats itself when clicking again on the box, but then back to place. Maybe to keep in mind: I'm using a reponsive design, which means those blocks can be vertical and horizontal after scaling the window. Any redevisions on the fiddle or suggustions would be great!

  • Magento - createBlock() in controller, can I access this in layout.xml?

    - by pspahn
    I have an index controller with a view action that does the following: echo $this->getLayout() ->createBlock('core/template','builder') ->setTemplate('pages/builder/view.phtml') ->setHeaderText($extra->getHeaderText()) ->setFooterText($extra->getFooterText()) ->setProducts($collection) ->toHtml(); Based on this, I am trying to perform layout updates in builder.xml (which is being set in the module's config.xml). However, I am not sure if you can target blocks instantiated in this manner. Based on the above block creation, am I able to perform the following: <layout version="0.1.0"> <builder_index_view> <!-- shouldn't this reference the createBlock() name argument? --> <reference name="builder"> <block type="page/html_header" name="builder.header" as="builder.header" template="pages/builder/header.phtml"/> </reference> </builder_index_view> </layout>

  • TPageControl tab area OnMouseEnter OnMouseLeave events

    - by daemon_x
    Hello, I need to catch the "OnMouseEnter" and "0nMouseLeave" for a certain area of the TPageControl component. With that specific area I mean the whole "tab header" rectangle. The problem is, that the page control doesn't catch the messages (I'm catching internal control messages CM_MOUSEENTER and CM_MOUSELEAVE) in the "empty" space. The aim for me is to draw a small arrow in the right empty side when user hovers in the red framed area (and drawing is just piece of cake) and erase it when leaves this area. And I'm don't care about the overflow of the tabs (which causes to draw scrolling double button) - that will never happen.
