  • Why is my input textbox extending outside margins in BlackBerry and Android, but not iOS?

    - by Dallas
    I have an input field that is extending well beyond the rest of the page, but as the question alludes to, it appears fine in iOS. I am wondering if anyone has run into this issue. My search button, which in iOS is on the right of the search textbox, actually wraps to the next "line" on the other two platforms. I am not using a table, just inside a div, and the CSS isn't doing anything fancy. Any ideas?

  • Button height rendering inconsistency in Firefox - why are input elements taller?

    - by George Edison
    Consider the following two elements: <button type="submit" class="button">Test</button> <a href="#" class="button">Test 2</a> ...which use the following style definition: .button { background-color: yellow; color: white; border: 1px solid orange; display: inline-block; font-size: 24pt; padding: 2px 16px; text-decoration: none; } This produces two buttons beside each other with an equal height in Chrome. However, Firefox renders the button on the left with a height 1px greater than the button on the right (the <a>): (I've enlarged the image above by 2x.) What do I need to do to get the two buttons to have the same height? It seems like the font-size is causing the problem - but I need that attribute. Fiddle: http://jsfiddle.net/FfRPY/

  • Why doesn't this require_once statement find the file? (PHP)

    - by ggfan
    I not sure what's going on..maybe I missed something simple. In my connectvars.php file, I connect to the database using the variables in my config.php folder. Here's the hierarchy: admin(folder) config.php includes(folder) connectvars.php I want to get information from config.php to use in connectvars.php, so I use: require_once("../admin/config.php"); But everytime I do this I get Warning: require_once(../admin/config.php) [function.require-once]: failed to open stream: No such file or directory in /home/a8879415/public_html/includes/connectvars.php on line 2 BUT when I type: require_once("admin/config.php");, it works. I thought I had to go up a level, then go down to admin, then get config.php. So how come I just need to go into the admin folder then get config.php?

  • Why does String.Equals(Object obj) check to see if this == null?

    - by m-y
    // Determines whether two strings match. [ReliabilityContract(Consistency.WillNotCorruptState, Cer.MayFail)] public override bool Equals(Object obj) { //this is necessary to guard against reverse-pinvokes and //other callers who do not use the callvirt instruction if (this == null) throw new NullReferenceException(); String str = obj as String; if (str == null) return false; if (Object.ReferenceEquals(this, obj)) return true; return EqualsHelper(this, str); } The part I don't understand is the fact that it is checking for the current instance, this, against null. The comment is a bit confusing, so I was wondering what does that comment actually mean? Can anyone give an example of how this could break if that check was not there, and does this mean that I should also place that check in my classes?

  • Why can't I set a layout for a page in a QStackedWidget in designer?

    - by cppguy
    Steps to reproduce in designer for Qt 4.8.0 I create a new dialog form in Qt Designer I add a QStackedWidget to the dialog I set the layout of the dialog to make the stacked layout size with the dialog I add a few controls to page one in the stacked widget I select the first page in the stacked widget in the right hand tree view of controls The icon next to that page (which is a QWidget) shows the page is missing a layout When I click one of the layout buttons above, it doesn't change the layout of the page QWidget, it changes the layout of the dialog even though I had explicitly selected the page. Is this a bug in designer? Am I missing something? I really don't want to add the layouts programatically as that prevents me from being able to layout the pages in designer in the same .ui file

  • Why does gcc warn about incompatible struct assignment with a `self = [super initDesignatedInit];' c

    - by gavinbeatty
    I have the following base/derived class setup in Objective-C: @interface ASCIICodeBase : NSObject { @protected char code_[4]; } - (Base *)initWithASCIICode:(const char *)code; @end @implementation ASCIICodeBase - (ASCIICodeBase *)initWithCode:(const char *)code len:(size_t)len { if (len == 0 || len > 3) { return nil; } if (self = [super init]) { memset(code_, 0, 4); strncpy(code_, code, 3); } return self; } @end @interface CountryCode : ASCIICodeBase - (CountryCode *)initWithCode:(const char *)code; @end @implementation CountryCode - (CountryCode *)initWithCode:(const char *)code { size_t len = strlen(code); if (len != 2) { return nil; } self = [super initWithCode:code len:len]; // here return self; } @end On the line marked "here", I get the following gcc warning: warning: incompatible Objective-C types assigning 'struct ASCIICodeBase *', expected 'struct CurrencyCode *' Is there something wrong with this code or should I have the ASCIICodeBase return id? Or maybe use a cast on the "here" line?

  • Why does this Bash regex match return an Exit Status of "2"?

    - by PreservedMoose
    I'm writing a Bash script that needs to scan for the existence of non-ASCII characters in filenames. I'm using the POSIX bracket regex syntax to match the non-ASCII characters, but for some reason, when I test for the match in an if/then statement, the test always returns an Exit Status of 2, and never matches my test string. Here's the code in question: FILEREQ_SOURCEFILE="Filename–WithNonAScII-Charàcters-05sec_23.98.mov" REGEX_MATCH_NONASCII="[^[:ascii:]]" if [[ $FILEREQ_SOURCEFILE =~ $REGEX_MATCH_NONASCII ]]; then echo "Exit Status: $?" echo "Matched!" else echo "Exit Status: $?" echo "No Match" fi This code always returns: Exit Status: 2 No Match I've read and re-read the bash-hackers.org explanation of how regex matching works, as well as this previous question on SO regarding matching non-ASCII characters, but for the life of me, I can't get this to work. What am I missing here?

  • Why does Application_Deactivated not get called on a pivot page?

    - by willmel
    For my Windows Phone 7 app, I have a main panorama page which opens up into a pivot control. The main panorama page correctly calls Activated/Deactivated, and restores correctly. But after visiting the pivot page, pressing the Windows key doesn't call Deactivated. When the app is relaunched with the back button, it goes right to how the page looked before tombstoning, but Activated is not called, and the page is not usable, and the back key doesn't work. Has anyone else experienced this problem before?

  • jQuery: click() function doesn't work on the <a> element.. why ?

    - by Patrick
    hi, I cannot trigger this click on this element $(this).find('.views-field-field-cover-fid').find('a.imagecache-coverimage').click(); The jQuery path is correct. Indeed if I print it, it gives the correct a element: console.log($(this).find('.views-field-field-cover-fid').find('a.imagecache-coverimage')); But for some reason the function click() doesn't work on it. thanks

  • Why is this writing part of the text to a new line? (Python)

    - by whatsherface
    I'm adding some new bits to one of the lines in a text file and then writing it along with the rest of the lines in the file to a new file. Referring to the if statement, I that to be all on the same line: x = 13.55553e9 y = 14.55553e9 z = 15.55553e9 infname = 'afilename' outfname = 'anotherone' oldfile = open(infname) lnum=1 for line in oldfile: if (lnum==18): line = "{0:.2e}".format(x)+' '+line+' '+"{0:.2e}".format(y)+' '+ {0:.2e}".format(z) newfile = open(outfname,'w') newfile.write(line) lnum=lnum+1 oldfile.close() newfile.close() but y and z are being written on the line below the rest of it. What am I missing here?

  • 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?

  • Why are cookies unrecognized when a link is clicked from an external source (i.e. Excel, Word, etc..

    - by Nick
    I noticed that when a link is clicked externally from the web browser, such as from Excel or Word, that my session cookie is initially unrecognized, even if the link opens up in a new tab of the same browser window. The browser ends up recognizing its cookie eventually, but I am puzzled as to why that initial link from Excel or Word doesn't work. To make it even more challenging, clicking a link works fine from Outlook. Does anybody know why this might be happening? I'm using the Zend Framework with PHP 5.3.

  • Why $(":select").focus does not work while $(":input").focus works?

    - by user605660
    Hi. I have a JQuery code which does something when input or select elements get focus. Although my code for input element works, select element does not work. Here is what I do. <body> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> $(document).ready(function(){ $(":input").focus(function () { //this works //do something }); $(":select").focus(function () { //this doesn't //do something }); }); </script> </body> I tried some variation on select, such as using $("select") instead of $(":select"), but did not work either. I am a beginner for JQuery. I appreciate if you could tell me how I can make it work. Thanks a lot!

  • Why are scrollbars appearing on my site on mobile devices?

    - by kcgolden
    I'm trying to make a small project site that's responsive using twitter-bootstrap and ember.js. It looks great on desktop and mostly scales to mobile devices except for one thing: x and y scrollbars appear on my android phone for the page. I don't know if this is the case on iPhone because I don't have one available at the moment. My site is here Can anyone see anything obvious in the inspector?
