  • jQuery find value then replace SRC

    - by Charles Web Dev
    Hello all, Can anyone see anything that is wrong with this code it just isn't working... I am tring to: get the value of #product-variants-option-0 search #preload for the relevant image and then change div.image img src to that image jQuery(document).ready(function($) { $('#product-variants-option-0').change(function() { // What is the sku of the current variant selection. var select_value = $(this).find(':selected').val(); if (select_value == "Kelly Green") { var keyword = "kly"; }; var new_src = $('#preload img[src*=keyword]'); $('div.image img').attr('src', new_src); }); }); The selection: <select class="single-option-selector-0" id="product-variants-option-0"> <option value="Kelly Green">Kelly Green</option> <option value="Navy">Navy</option> <option value="Olive">Olive</option> <option value="Cocoa">Cocoa</option> </select> I'm trying to search an unordered list: <ul id="preload" style="display:none;"> <li><img src="0z-kelly-green-medium.jpg"/></li> <li><img src="0z-olive-medium.jpg"/></li> </ul> The image I'm trying to replace is this:

  • Game login authentication and security.

    - by Charles
    First off I will say I am completely new to security in coding. I am currently helping a friend develop a small game (in Python) which will have a login server. I don't have much knowledge regarding security, but I know many games do have issues with this. Everything from 3rd party applications (bots) to WPE packet manipulation. Considering how small this game will be and the limited user base, I doubt we will have serious issues, but would like to try our best to limit problems. I am not sure where to start or what methods I should use, or what's worth it. For example, sending data to the server such as login name and password. I was told his information should be encrypted when sending, so in-case someone was viewing it (with whatever means), that they couldn't get into the account. However, if someone is able to capture the encrypted string, wouldn't this string always work since it's decrypted server side? In other words, someone could just capture the packet, reuse it, and still gain access to the account? The main goal I am really looking for is to make sure the players are logging into the game with the client we provide, and to make sure it's 'secure' (broad, I know). I have looked around at different methods such as Public and Private Key encryption, which I am sure any hex editor could eventually find. There are many other methods that seem way over my head at the moment and leave the impression of overkill. I realize nothing is 100% secure. I am just looking for any input or reading material (links) to accomplish the main goal stated above. Would appreciate any help, thanks.

  • how to link with static mySQL C library with Visual Studio 2008?

    - by Jean-Denis Muys
    Hi, My project is running fine, but its requirement for some DLLs means it cannot be simply dragged and dropped by the end user. The DLLs are not loaded when put side by side with my executable, because my executable is not an application, and its location is not in the few locations where Windows looks for DLL. I already asked a question about how to make their loading happen. None of the suggestions worked (see the question at http://stackoverflow.com/questions/2637499/how-can-a-win32-app-plugin-load-its-dll-in-its-own-directory) So I am now exploring another way: get rid of the DLLs altogether, and link with static versions of them. This is failing for the last of those DLLs. So I am at this point where all but one of the libraries are statically linked, and everything is fine. The last library is the standard C library for mySQL, aka Connector/C. The problem I have may or may not be related with that origin. Whenever I switched to the static library in the linker additional dependency, I get the following errors (log at the end): 1- about 40 duplicate symbols (e.g. _toupper) mutually between LIBCMT.lib and MSVCRT.lib. Interestingly, I can't control the inclusion of these two libraries: they are from Visual Studio and automatically included. So why are these symbol duplicate when I include mySQL's static lib, but not its DLL? Searching C:\Program Files\Microsoft Visual Studio 9.0\VC\lib\MSVCRT.lib: Searching C:\Program Files\Microsoft Visual Studio 9.0\VC\lib\OLDNAMES.lib: Searching C:\Program Files\Microsoft Visual Studio 9.0\VC\lib\msvcprt.lib: Searching C:\Program Files\Microsoft Visual Studio 9.0\VC\lib\LIBCMT.lib: LIBCMT.lib(setlocal.obj) : error LNK2005: _setlocale already defined in MSVCRT.lib(MSVCR90.dll) Searching C:\Program Files\Microsoft Visual Studio 9.0\VC\lib\MSVCRT.lib: MSVCRT.lib(MSVCR90.dll) : error LNK2005: _toupper already defined in LIBCMT.lib(toupper.obj) 2- two warnings that MSVCRT and LIBCMT conflicts with use of other libs, with a suggestion to use /NODEFAULTLIB:library:. I don't understand that suggestion: what am I supposed to do and how? LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library LINK : warning LNK4098: defaultlib 'LIBCMT' conflicts with use of other libs; use /NODEFAULTLIB:library 3- an external symbol is undefined: _main. So does that mean that the static mySQL lib (but not the DLL) references a _main symbol? For the sake of it, I tried to define an empty function named _main() in my code, with no difference. LIBCMT.lib(crt0.obj) : error LNK2001: unresolved external symbol _main As mentioned in my first question, my code is a port of a fully working Mac version of the code. Its a plugin for a host application that I don't control. The port currently works, albeit with installation issues due to that lone remaining DLL. As a Mac programmer I am rather disoriented with Visual Studio and Windows which I find confusing, poorly designed and documented, with error messages that are very difficult to grasp and act upon. So I will be very grateful for any help.

  • iPhone UITableView stutters with custom cells. How can I get it to scroll smoothly?

    - by Charles S.
    I'm using a UITableView to display custom cells created with Interface Builder. The table scrolling isn't very smooth (it "stutters") which leaves me to believe cells aren't being reused. Is there something wrong with this code? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"TwitterCell"; TwitterCell *cell = (TwitterCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil){ //new cell NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"TwitterCell" owner:nil options:nil]; for(id currentObject in topLevelObjects) { if([currentObject isKindOfClass:[TwitterCell class]]) { cell = (TwitterCell *)currentObject; break; } } } if([self.tweets count] > 0) { cell.lblUser.text = [[self.tweets objectAtIndex:[indexPath row]] username]; cell.lblTime.text = [[self.tweets objectAtIndex:[indexPath row]] time]; [cell.txtText setText:[[self.tweets objectAtIndex:[indexPath row]] text]]; [[cell imgImage] setImage:[[self.tweets objectAtIndex:[indexPath row]] image]]; } else { cell.txtText.text = @"Loading..."; } cell.selectionStyle = UITableViewCellSelectionStyleNone; return cell; }

  • How to Detect IE Version on Vista and Above

    - by Charles Gargent
    I would like to detect what version IE is running on Vista and above (I am developing on 7). I currently use WMI on XP, but it appears that this is no more. I have searched for an answer and so far I have found the following solutions: Using System.Windows.Forms WebBrowser wb = new WebBrowser; wb.Version; SELECT path,filename,extension,version FROM CIM_DataFile WHERE path="\\Program Files\\Internet Explorer\\" AND filename="iexplore" AND extension="exe" AND version>"8.0" And there is probably a way of looking up in the registry. Is there must a more elegant solution to this?

  • Making Latex typeset given text on two facing pages

    - by Charles Stewart
    How do I encourage/make Latex typeset some portion of text so that it will all appear on a consecutive even-page, odd-page pair of pages? With trial and error, \nopagebreak can be coaxed into doing this, but is there a strategy that Just Works? Something like a samepage environment would be ideal, but one that: Will force a pagebreak on odd pages if that is needed to get all the text on facing pages; Allows up to one page break anywhere in the environment body, and fails noisily if that can't be ensured.

  • Capture *all* display-characters in JavaScript?

    - by Jean-Charles
    I was given an unusual request recently that I'm having the most difficult time addressing that involves capturing all display-characters when typed into a text box. The set up is as follows: I have a text box that has a maxlength of 10 characters. When the user attempts to type more than 10 characters, I need to notify the user that they're typing beyond the character count limit. The simplest solution would be to specify a maxlength of 11, test the length on every keyup, and truncate back down to 10 characters but this solution seems a bit kludgy. What I'd prefer to do is capture the character before keyup and, depending on whether or not it is a display-character, present the notification to the user and prevent the default action. A white-list would be challenging since we handle a lot of international data. I've played around with every combination of keydown, keypress, and keyup, reading event.keyCode, event.charCode, and event.which, but I can't find a single combination that works across all browsers. The best I could manage is the following that works properly in =IE6, Chrome5, FF3.6, but fails in Opera: NOTE: The following code utilizes jQuery. $(function(){ $('#textbox').keypress(function(e){ var $this = $(this); var key = ('undefined'==typeof e.which?e.keyCode:e.which); if ($this.val().length==($this.attr('maxlength')||10)) { switch(key){ case 13: //return case 9: //tab case 27: //escape case 8: //backspace case 0: //other non-alphanumeric break; default: alert('no - '+e.charCode+' - '+e.which+' - '+e.keyCode); return false; }; } }); }); I'll grant that what I'm doing is likely over-engineering the solution but now that I'm invested in it, I'd like to know of a solution. Thanks for your help!

  • CSS layout problem on Firefox with filling space between end of left column and footer

    - by Jean
    Basically, the left column is supposed to extend to the footer with the continuous red color. However, in Firefox on pages with lots of text, the column does not extend to the footer and leaves a large white gap--see site: http://library.luhs.org/JHSII/about.html I've tried readjusting the heights, creating the sticky footer, and other things I've read about on this site. So I admit that I'm stumped, and what's really odd is that the layout seems to work in IE as there is no white space! I didn't create the site, but I recently inherited it and trying to work through the mess Any help is much appreciated, here's the CSS #html,body{ margin:0; padding:0; border:0; height:100%; } #body{ background:#ffffff; min-width:965px; text-align:center; width: 600px; font: Geneva, Arial, Helvetica, sans-serif; } #.style7{ clear:both; height:1px; overflow:hidden; line-height:1%; font-size:0px; margin-bottom:-1px; } #fullheightcontainer{ margin-left:auto; margin-right:auto; text-align:left; position:relative; width:965px; height:100%; } #wrapper{ min-height:100%; height:100%; background:#660000; background-color: #660000; background-repeat: repeat; } #wrapp\65 r{ height:auto; } # html wrapper{ height:100%; } #outer{ z-index:1; position:relative; margin-left:150px; width:815px; background:#FFFFFF; height:100%; background-color: #FFFFFF; } #left{ width:151px; float:left; display:inline; position:relative; margin-left:-150px; } padding: 20px; border: 0; margin: 0 0 0 240px *>html #left{width:150px;} #container-left{ width:150px; color: #CCCCCC; } * html #left{margin-right:-3px;} #center{ width:800px; float:right; display:inline; margin-left:-1px; } #clearheadercenter{ height:125px; overflow:hidden; } #clearfootercenter{ height:50px; overflow:hidden; } #footer{ z-index:1; position:relative; clear: both; width:965px; height:50px; overflow:hidden; margin-top:-50px; background-color: #660000; } #subfooter1{ background:#FFFFCC; text-align:left; margin-left:150px; height:50px; } #header{ z-index:1; position:absolute; top:0px; width:815px; margin-left:150px; height:100px; overflow:hidden; background-color: #660000; } #subheader1{ background:#FFFFCC; text-align:center; height:70px; } #gfx_bg_middle{ top:0px; position:absolute; height:100%; overflow:hidden; width:815px; margin-left:150px; background:#FFFFFF; } # html #gfx_bg_middle{ display:none; } #floatingnav { margin: 5px 10px 5px 5px; padding: 0px 5px 5px; float: right; font: .75em/1.35em Geneva, Arial, Helvetica, sans-serif; height: 600px; width: 300px; } #floatingnav a { color: #630; } #floatingnav ul { margin-top: -5; } #.floatright { float: right; margin: 0 0 10px 10px; border: 1px solid #666; padding: 2px; } #outer{ word-wrap:break-word; } #table.s1 { border-width: medium; border-spacing: 2px; border-style: none; border-color: rgb(85, 0, 0); border-collapse: collapse; background-color: white; } #table.s1 th { border-width: medium; padding: 2px; border-style: groove; border-color: red; background-color: white; -moz-border-radius: 0px 0px 0px 0px; } #table.s1 td { border-width: medium; padding: 2px; border-style: groove; border-color: #660000; background-color: #FFFFFF; -moz-border-radius: 0px 0px 0px 0px; } #a:link { color: #000066; } #a:visited { color: #000066; } #p.sample { font-family: serif; font-style: normal; font-variant: normal; font-weight: normal; font-size: medium; line-height: 100%; word-spacing: normal; letter-spacing: normal; text-decoration: none; text-transform: none; text-align: left; text-indent: 0ex; }

  • JW Player - How can I add an event listener for fullscreen toggling?

    - by Charles
    I'm using JW Player 4.5 on my site and I need to add an event listener for when fullscreen is toggled. The reason for this is to switch between a low-def version and high-def version. The default video will be the low-def version and when they switch to a fullscreen display, it will change to the high-def version. According to http://developer.longtailvideo.com/trac/wiki/Player5Events, the ViewEvent.JWPLAYER_VIEW_FULLSCREEN1 event can only be called from Actionscript. I need it to be from Javascript... Is there any way to achieve this? Can you recommend a better solution?

  • Using MD5 to generate an encryption key from password?

    - by Charles
    I'm writing a simple program for file encryption. Mostly as an academic exercise but possibly for future serious use. All of the heavy lifting is done with third-party libraries, but putting the pieces together in a secure manner is still quite a challenge for the non-cryptographer. Basically, I've got just about everything working the way I think it should. I'm using 128-bit AES for the encryption with a 128-bit key length. I want users to be able to enter in variable-length passwords, so I decided to hash the password with MD5 and then use the hash as the key. I figured this was acceptable--the key is always supposed to be a secret, so there's no reason to worry about collision attacks. Now that I've implemented this, I ran across a couple articles indicating that this is a bad idea. My question is: why? If a good password is chosen, the cipher is supposed to be strong enough on its own to never reveal the key except via an extraordinary (read: currently infeasible) brute-force effort, right? Should I be using something like PBKDF2 to generate the key or is that just overkill for all but the most extreme cryptographic applications?

  • Performance Tricks for C# Logging

    - by Charles
    I am looking into C# logging and I do not want my log messages to spend any time processing if the message is below the logging threshold. The best I can see log4net does is a threshold check AFTER evaluating the log parameters. Example: _logger.Debug( "My complicated log message " + thisFunctionTakesALongTime() + " will take a long time" ) Even if the threshold is above Debug, thisFunctionTakesALongTime will still be evaluated. In log4net you are supposed to use _logger.isDebugEnabled so you end up with if( _logger.isDebugEnabled ) _logger.Debug( "Much faster" ) I want to know if there is a better solution for .net logging that does not involve a check each time I want to log. In C++ I am allowed to do LOG_DEBUG( "My complicated log message " + thisFunctionTakesALongTime() + " will take no time" ) since my LOG_DEBUG macro does the log level check itself. This frees me to have a 1 line log message throughout my app which I greatly prefer. Anyone know of a way to replicate this behavior in C#?

  • Query MySQL data from Excel (or vice-versa)

    - by Charles
    I'm trying to automate a tedious problem. I get large Excel (.xls or .csv, whatever's more convenient) files with lists of people. I want to compare these against my MySQL database.* At the moment I'm exporting MySQL tables and reading them from an Excel spreadsheet. At that point it's not difficult to use =LOOKUP() and such commands to do the work I need, and of course the various text processing I need to do is easy enough to do in Excel. But I can't help but think that this is more work than it needs to be. Is there some way to get at the MySQL data directly from Excel? Alternately, is there a way I could access a reasonably large (~10k records) csv file in a sql script? This seems to be rather basic, but I haven't managed to make it work so far. I found an ODBC connection for MySQL but that doesn't seem to do what I need. In particular, I'm testing whether the name matches or whether any of four email addresses match. I also return information on what matched for the benefit of the next person to use the data, something like "Name 'Bob Smith' not found, but 'Robert Smith' matches on email address robert.smith@foo".

  • Facebook status.get API throws 500 HTTP status code

    - by Charles Prakash Dasari
    I have an APP that calls Facebook status.get method via the REST server - restserver.php using session key method. This app works fine for most of the users, but for one user I consistently receive HTTP 500 status code. Since this doesn't have any specific Facebook error message, it is almost impossible for me to debug this. Anyone faced a similar problem? What could be wrong with this user account? I checked the privacy options that I could think of and they look fine. Also, for the same user, I can use friends.get method without any problem. EDIT: I tried in Facebook forums as well, but it was of no use. Any pointers in the direction towards debugging/troubleshooting this problem are also appreciated.
