• How to model a mutually exclusive relationship in sql server

  - by littlechris

  Hi, I have to add functionality to an existing application and I've run into a data situation that I'm not sure how to model. I am being restricted to the creation of new tables and code. If I need to alter the existing structure I think my client may reject the proposal..although if its the only way to get it right this is what I will have to do. I have an Item table that can me link to any number of tables, and these tables may increase over time. The Item can only me linked to one other table, but the record in the other table may have many items linked to it. Examples of the tables/entities being linked to are "Person", "Vehicle", "Building", "Office". These are all separate tables. Example of Items are "Pen", "Stapler", "Cushion", "Tyre", "A4 Paper", "Plastic Bag", "Poster", "Decoration" For instance a "Poster" may be allocated to a "Person" or "Office" or "Building". In the future if they add a "Conference Room" table it may also be added to that. My intital thoughts are: Item { ID, Name } LinkedItem { ItemID, LinkedToTableName, LinkedToID } The LinkedToTableName field will then allow me to identify the correct table to link to in my code. I'm not overly happy with this solution, but I can't quite think of anything else. Please help! :) Thanks!

• Nested hyperlinks in XHTML 1.1 document

  - by Nazgulled

  Hi, I'm doing a simple widget for WordPress that fetches the most recent tweets from the RSS feed provided by Twitter. This widget parses any link posted on a tweet, it also parses mentions (ie: @username) and trending topics (ie: #nowplaying). For these 3 situations, it creates links pointing to some Twitter feature. For instance: "Hi @UserA, check out the song Foo from FooBar that I'm listening, it's awesome. #nowplaying" And it will parse into this: Hi <a href="http://twitter.com/UserA">@UserA</a>, check out the song Foo from FooBar that I'm listening, it's awesome. <a href="http://twitter.com/#search?q=nowplaying">#nowplaying</a> Now now I need to add a global link to the whole message, like this: <a href="http://twitter.com/UserA/statuses/1234567890"> Hi <a href="http://twitter.com/UserA">@UserA</a>, check out the song Foo from FooBar that I'm listening, it's awesome. <a href="http://twitter.com/#search?q=nowplaying">#nowplaying</a> </a> But this code does not validate and it doesn't work anyways (the browsers don't really seem to know what to do with it). Any suggestions how could I fix this?

• How do i write task? (parallel code)

  - by acidzombie24

  I am impressed with intel thread building blocks. I like how i should write task and not thread code and i like how it works under the hood with my limited understanding (task are in a pool, there wont be 100 threads on 4cores, a task is not guaranteed to run because it isnt on its own thread and may be far into the pool. But it may be run with another related task so you cant do bad things like typical thread unsafe code). I wanted to know more about writing task. I like the 'Task-based Multithreading - How to Program for 100 cores' video here http://www.gdcvault.com/sponsor.php?sponsor_id=1 (currently second last link. WARNING it isnt 'great'). My fav part was 'solving the maze is better done in parallel' which is around the 48min mark (you can click the link on the left side). However i like to see more code examples and some API of how to write task. Does anyone have a good resource? I have no idea how a class or pieces of code may look after pushing it onto a pool or how weird code may look when you need to make a copy of everything and how much of everything is pushed onto a pool.

• @attribute elements in XML

  - by danit

  Here is my XML: ["link"]=> array(2) { [0]=> object(SimpleXMLElement)#244 (1) { ["@attributes"]=> array(3) { ["type"]=> string(9) "text/html" ["href"]=> string(48) "http://twitter.com/MoodleDan/statuses/1226112723" ["rel"]=> string(9) "alternate" } } [1]=> object(SimpleXMLElement)#245 (1) { ["@attributes"]=> array(3) { ["type"]=> string(9) "image/png" ["href"]=> string(59) "http://a3.twimg.com/profile_images/226895523/Dan_normal.png" ["rel"]=> string(5) "image" } } } ["author"]=> object(SimpleXMLElement)#246 (2) { ["name"]=> string(14) "Dan Humpherson" ["uri"]=> string(16) "http://vl3.co.uk" } The above XML is part of a larger array, but how do i get the href -> ["href"]=> string(59) "http://a3.twimg.com/profile_images/226895523/Dan_normal.png" Element to echo in PHP? This is what I tried (Wrong I know) foreach ($entry->link as $img) { echo $img->href; echo "<img src='". $img ."' />"; }

  Well I am new to this orm stuff. We have to create a large project .

• toggleClass messing something up.

  - by Mathias Nielsen

  Hi I am using playing around with the Pretty-checkboxes-plugin and have a problem. The plugin can be seen here http://aaronweyenberg.com/90/pretty-checkboxes-with-jquery As you can see, this uses two links to select and deselect. I want it to only use one link and then change the class to make it work the other way the next time it is clicked. It should be simple enough. I have been trying to get it working with toggleClass. I simply put in the toggleClass statement so the code looks like so: $(document).ready(function() { /* see if anything is previously checked and reflect that in the view*/ $(".checklist input:checked").parent().addClass("selected"); /* handle the user selections */ $(".checklist .checkbox-select").click( function(event) { event.preventDefault(); $(this).parent().addClass("selected"); $(this).parent().find(":checkbox").attr("checked","checked"); $(this).toggleClass("checkbox-select checkbox-deselect"); } ); $(".checklist .checkbox-deselect").click( function(event) { event.preventDefault(); $(this).parent().removeClass("selected"); $(this).parent().find(":checkbox").removeAttr("checked"); $(this).toggleClass("checkbox-select checkbox-deselect"); } ); }); This works to some extend. The classes toggle just fine, but the rest of the code only works the first time it is run. All subsequent clicks just toggle the class og the link and nothing else. Does anyone have any idea why this is?

• How to use Grails Spring Security Plugin to require logging in before access an action?

  - by Hoàng Long

  Hi all, I know that I can use annotation or Request mapping to restrict access to an ACTION by some specific ROLES. But now I have a different circumstance. My scenario is: every user of my site can create posts, and they can make their own post public, private, or only share to some other users. I implement sharing post by a database table PERMISSION, which specify if a user have the right to view a post or not. The problem arises here is that when a customer access a post through a direct link, how can I determine he/she have the privilege to view it? There's 3 circumstances: The post is public, so it can be viewed by anyone (include not-login user) The post is private, so only the login-owner can view it The post is sharing, it means only the login-user that is shared and the owner can view it. I want to process like this: If the requested post is public: ok. If the requested post is private/sharing: I want to redirect the customer to the login page; after logging in, the user will be re-direct to the page he wants to see. The problem here is that I can redirect the user to login controller/ auth action, but after that I don't know how to redirect it back. The link to every post is different by post_id, so I can't use SpringSecurityUtils.securityConfig.successHandler.defaultTargetUrl Could anyone know a way to do this?

• Replace relative urls to absolute

  - by Rocky Singh

  I have the html source of a page in a form of string with me: <html> <head> <link rel="stylesheet" type="text/css" href="/css/all.css" /> </head> <body> <a href="/test.aspx">Test</a> <a href="http://mysite.com">Test</a> <img src="/images/test.jpg"/> <img src="http://mysite.com/images/test.jpg"/> </body> </html> I want to convert all the relative paths to absolute. I want the output be: <html> <head> <link rel="stylesheet" type="text/css" href="http://mysite.com/css/all.css" /> </head> <body> <a href="http://mysite.com/test.aspx">Test</a> <a href="http://mysite.com">Test</a> <img src="http://mysite.com/images/test.jpg"/> <img src="http://mysite.com/images/test.jpg"/> </body> </html> Note: I want only the relative paths to be converted to absolute ones in that string. The absolute ones which are already in that string should not be touched, they are fine to me as they are already absolute. Can this be done by regex or other means?

• Javascript Confirm Delete in One PHP File (on href)

  - by gamerzfuse

  <p><span class="linky"><a href="deletephone.php?id=' . $row['id'] . '">Delete Phone</a></span></p><br /> I have the above code that I am using to link to a delete script. I want to somehow incorporate Javascript with a simple onclick confirmation. This way if they choose OK, I can run the code to delete the item from the database, but if they choose Cancel then I can cancel the operation and do nothing. I have tried a whole variety of functions with changing the window.location to the delete file, and trying to cancel the href= if they choose Cancel, but it always goes to the link regardless of what the user clicks. I would like to be able to keep the delete functions inside the same PHP file if possible, but this is not necessary at all. Thanks in advance! ASIDE: If there is a simple PHP way to check IF the alert was confirmed or denied, that could work also. Any way to check what the user chooses and then run my simple delete PHP command.

• Visual C++ overrides/mock objects for unit testing?

  - by Mark

  When I'm running unit tests, I want to be able to "stub out" or create a mock object, but I'm running into DLL Hell. For example: There are two DLL libraries built: A.dll and B.dll -- Classes in A.dll have calls to classes in B.dll so when A.dll was built, the link line was using B.lib for the defintions. My test driver (Foo.exe) is testing classes in A.dll, so it links against A.lib. However, I want to "stub out" some of the calls A.dll makes to B.dll with simple versions (return basic value, no DB look up, etc). I can't build an Override.dll that just overrides the needed methods (not entire classes) and replace B.dll because Foo.exe will A) complain that B.dll is missing if I just remove it and put Override.dll in it's place or B) if I rename Override.dll to B.dll, Foo.exe complains that there are unresolved symbols because Override.dll is not a complete implementation of B.dll. Is there a way to do this? Is there a way to statically link Foo.exe with A.lib, B.lib and Override.lib such that it will work without having to completely rebuild A.lib and B.lib to remove the __delcspec(dllexport)? Is there another option?

• Git branch strategy for small dev team

  - by Bilal Aslam

  We have a web app that we update and release almost daily. We use git as our VCS, and our current branching strategy is very simple and broken: we have a master branch and we check changes that we 'feel good about' into it. This works, but only until we check in a breaking change. Does anyone have a favorite git branch strategy for small teams which meets the following requirements: Works well for teams of 2 to 3 developers Lightweight, and not too much process Allows devs to isolate work on bug fixes and larger features with ease Allows us to keep a stable branch (for those 'oh crap' moments when we have to get our production servers working) Ideally, I'd love to see your step-by-step process for a dev working on a new bug

• Unable to persist objects in GAE JDO

  - by Basil Dsouza

  Hello Guys, I am completely fresh to both JDO and GAE, and have been struggling to get my data layer to persist any code at all! The issues I am facing may be very simple, but I just cant seem to find any a way no matter what solution I try. Firstly the problem: (Slightly simplified, but still contains all the info necessary) My data model is as such: User: (primary key) String emailID String firstName Car: (primary key) User user (primary key) String registration String model This was the initial datamodel. I implemented a CarPK object to get a composite primary key of the User and the registration. However that ran into a variety of issues. (Which i will save for another time/question) I then changed the design as such: User: (Unchanged) Car: (primary key) String fauxPK (here fauxPK = user.getEmailID() + SEP + registration) User user String registration String model This works fine for the user, and it can insert and retrieve user objects. However when i try to insert a Car Object, i get the following error: "Cannot have a java.lang.String primary key and be a child object" Found the following helpful link about it: http://stackoverflow.com/questions/2063467/persist-list-of-objects Went to the link suggested there, that explains how to create Keys, however they keep talking about "Entity Groups" and "Entity Group Parents". But I cant seem to find any articles or sites that explain what are "Entity Group"s or an "Entity Group Parents" I could try fiddling around some more to figure out if i can store an object somehow, But I am running sort on patience and also would rather understand and implement than vice versa. So i would appreciate any docs (even if its huge) that covers all these points, and preferably has some examples that go beyond the very basic data modeling. And thanks for reading such a long post :)

• Fast, easy, and secure method to perform DB actions with GET

  - by rob - not a robber

  Hey All, Sort of a methods/best practices question here that I am sure has been addressed, yet I can't find a solution based on the vague search terms I enter. I know starting off the question with "Fast and easy" will probably draw out a few sighs, so my apologies. Here is the deal. I have a logged in area where an ADMIN can do a whole host of POST operations to input data relating to their profile. The way I have data structured is pretty distinct and well segmented in most tables as it relates to the ID of the admin. Now, I have a table where I dump one type of data into and differentiate this data by assigning the ADMIN's unique ID to each record. In other words, all ADMINs have this one type of data writing to this table. I just differentiate by the ADMIN ID with each record. I was planning on letting the ADMIN remove these records by clicking on a link with a query string - obviously using GET. Obviously, the query structure is in the link so any logged in admin could then exploit the URL and delete a competitor's records. Is the only way to safely do this through POST or should I pass through the session info that includes password and validate it against the ADMIN ID that is requesting the delete? This is obviously much more work for me. As they said in the auto repair biz I used to work in... there are 3 ways to do a job: Fast, Good, and Cheap. You can only have two at a time. Fast and cheap will not be good. Good and cheap will not have fast turnaround. Fast and good will NOT be cheap. haha I guess that applies here... can never have Fast, Easy and Secure all at once ;) Thanks in advance...

• What is the simplest method to fill the area under a geom_freqpoly line?

  - by mattrepl

  The x-axis is time broken up into time intervals. There is an interval column in the data frame that specifies the time for each row. The column is a factor, where each interval is a different factor level. Plotting a histogram or line using geom_histogram and geom_freqpoly works great, but I'd like to have a line, like that provided by geom_freqpoly, with the area filled. Currently I'm using geom_freqpoly like this: ggplot(quake.data, aes(interval, fill=tweet.type)) + geom_freqpoly(aes(group = tweet.type, colour = tweet.type)) + opts(axis.text.x=theme_text(angle=-60, hjust=0, size = 6)) I would prefer to have a filled area, such as provided by geom_density, but without smoothing the line: UPDATE: The geom_area has been suggested, is there any way to use a ggplot2-generated statistic, such as ..count.., for the geom_area's y-values? Or, does the count aggregation need to occur prior to using ggplot2?

• jQuery dynamic css loading weired behavior

  - by jimpsr

  The app I am working on requires dynamic loading of css and js, right now the solution is as follows: myapp.loadCss = function(css){ $("head").append("<link>"); cssDom = $("head").children(":last"); cssDom.attr({rel: "stylesheet", type: "text/css", href: css }); } myapp.loadJs = funciton(js){ ... //$.ajax call is used in synchronized mode to make sure the js is fully loaded } } When some widgets need to be load, the usual call with be myapp.loadCss('/widgets/widget1/css/example.css'); myapp.loadJs('/wiggets/widget1/js/example.js'); The weired thing is that once a while (1 out of 10 or 20), the newly created dom elements from example.js will not be able to get its css from example.css, it seems however my loadCss method does not load the css in a synchronized mode? I have tried to replace my loadCss with the the following code: myapp.loadCss(css){ $('<link href="' + css + '" rel="stylesheet" type="text/css" />').appendTo($('head')); } It seems to be OK then (I refreshed the webpage a hundred times for verification :-( ) But unfortunately this method failed in IE(IE7, not tested in IE6, 8) Is there any better solution for this?

• hiding buttons in master page

  - by pankaj

  Hi, I am working on an app where i am having some linkbuttons in master page. I want to display them depending upon the authorization given to them once they logs in. I have initially made all of them visible false and then i am checking the authorisation in the aspx.cs class of master page. I make the link button visible depending upon the right granted to the user. But it is making all the link buttons visible. Instead it should only make two of them visible and rest should be hidden. Following is my code from MasterPage.aspx.cs: ArrayList arrlstUserRoles = new ArrayList(); arrlstUserRoles = (ArrayList)Session["Roles"]; for (int j = 0; j < arrlstUserRoles.Count; j++) { if (int.Parse(arrlstUserRoles[j].ToString()) == 1) { lbtnRetailer.Visible = true; } else if (int.Parse(arrlstUserRoles[j].ToString()) == 2) { lbtnCategory.Visible = true; } else if (int.Parse(arrlstUserRoles[j].ToString()) == 3) { lbtnCouponTemplate.Visible = true; } else if (int.Parse(arrlstUserRoles[j].ToString()) == 4) { //lbtnStoreManagement.Visible = true; } else if (int.Parse(arrlstUserRoles[j].ToString()) == 5) { lbtnStoreManagement.Visible = true; } else if (int.Parse(arrlstUserRoles[j].ToString()) == 6) { lbtnContentManagement.Visible = true; } else if (int.Parse(arrlstUserRoles[j].ToString()) == 7) { //lbtnStoreManagement.Visible = true; } }

• Differences setting content in Forms.WebBrowser control via DocumentText vs. Url

  - by jeffamaphone

  If I generate some HTML and have it in a string and then say: myWebBrowser.DocumentText = string; It seems to work just fine, except none of the images load (I get the broken image graphic). If, however, I write the string to a file and then say: myWebBrowser.Url = new Uri("file://myfile.html"); Everything works just fine. My question is, what's going on under the covers here that is different? I've verified in both cases that the path to the images (via RClick-View Source) is the same and that all the images do, indeed, exist. In both cases the HTML is exactly the same. Any light that could be shed on this would be appreciated. Thanks!

• CakePHP hasMany relationship with multiple columns

  - by Muhammad Yasir

  Hi, I am using CakePHP framework to build a web application. The simplest form of my problem is this: I have a users table and a messages table with corresponding models. Messages are sent from a user to another user. So messages table has columns from_id and to_id in it, both referencing to id of users. I am able to link Message model to User model by using $belongsTo but I am unable to link User model with Message model (in reverse direction) by using $hasMany in the same manner. var $hasMany = array( 'From' => array( 'className' => 'Message', 'foreignKey' => 'from_id', 'dependent' => false, 'conditions' => '', 'fields' => '', 'order' => '', 'limit' => '', 'offset' => '', 'exclusive' => '', 'finderQuery' => '', 'counterQuery' => '' ), 'To' => array( 'className' => 'Message', 'foreignKey' => 'to_id', 'dependent' => false, 'conditions' => '', 'fields' => '', 'order' => '', 'limit' => '', 'offset' => '', 'exclusive' => '', 'finderQuery' => '', 'counterQuery' => '' ) ); What can do here? Any ideas? Thanks for any help.

• LNK 1104 error to lib file - Continues despite removing includes and links

  - by user1556594

  A link error to a lib file popped up out of the blue in a c++ application of mine after code was working fine in my last session. Error 1 error LNK1104: cannot open file '..........\Program Files (x86)\FMOD SoundSystem\FMOD Programmers API Windows\api\lib\fmodex_vc.lib' I triple checked my project directories were set up correctly to link to the lib file, that the file existed in said directory and that it was a working version of the .lib. My next step was to remove the includes to the file and the links to bypass the error and work on the rest of my code until the problem was solved. The error remains, however, despite: Commenting out absolutely every include relating to the lib. Commenting out absolutely every line of code dependant on the includes. Removing the directory from VC++ Directories in the project properties. Checking the Additional Library Directories field was also clear of references. To my understanding this should have made the library and related code virtually non-existant to the compiler. What am I missing? The library itself is fmodex_vc.lib - part of the FMOD API for providing sound to interactive applications. Again, the application was working one session, but failed to compile the next. I hadn't touched the code since so this led me to believe some aspect of VS is at fault. I'd like to avoid the time involded in re-installing if possible as I'm on the clock for a review tomorrow evening and there are a few more things I'd like to smooth out before then. If necessary, however, I won't hesitate. Very much appreciate the help.

• Using jQuery with Windows 8 Metro JavaScript App causes security error

  - by patridge

  Since it sounded like jQuery was an option for Metro JavaScript apps, I was starting to look forward to Windows 8 dev. I installed Visual Studio 2012 Express RC and started a new project (both empty and grid templates have the same problem). I made a local copy of jQuery 1.7.2 and added it as a script reference. <!-- SomeTestApp references --> <link href="/css/default.css" rel="stylesheet" /> <script src="/js/jquery-1.7.2.js"></script> <script src="/js/default.js"></script> Unfortunately, as soon as I ran the resulting app it tosses out a console error: HTML1701: Unable to add dynamic content ' a' A script attempted to inject dynamic content, or elements previously modified dynamically, that might be unsafe. For example, using the innerHTML property to add script or malformed HTML will generate this exception. Use the toStaticHTML method to filter dynamic content, or explicitly create elements and attributes with a method such as createElement. For more information, see http://go.microsoft.com/fwlink/?LinkID=247104. I slapped a breakpoint in a non-minified version of jQuery and found the offending line: div.innerHTML = " <link/><table></table><a href='/a' style='top:1px;float:left;opacity:.55;'>a</a><input type='checkbox'/>"; Apparently, the security model for Metro apps forbids creating elements this way. This error doesn't cause any immediate issues for the user, but given its location, I am worried it will cause capability-discovery tests in jQuery to fail that shouldn't. I definitely want jQuery $.Deferred for making just about everything easier. I would prefer to be able to use the selector engine and event handling systems, but I would live without them if I had to. How does one get the latest jQuery to play nicely with Metro development?

• How to let one external stylsheet selectively overrule the other

  - by Ferdy

  I'm stunned by a simple thing that I want to accomplish but does not work. I have a website and I want it to support themes, which are a named set of CSS + images. No matter which theme is selected, I always include the main CSS file, which is the default theme. On top of that I'm loading a second stylesheet, the one that is theme-specific, like so: <link rel="stylesheet" type="text/css" href="css/main.css" title=main" media="screen" /> <link rel="stylesheet" type="text/css" href="themes/<?= $style ?>/css/<?= $style ?>.css" title="<?= $style ?>" media="screen" /> My idea is that the theme specific css should not be a full copy of the main css file. Instead, it should only contain CSS rules that overrule those of the main.css file. This makes themes much smaller and easier to maintain. I thought I could simply load two external stylesheets after each other and that for conflicting rules it will always use the theme specific css, the second file. However, it does not seem to work. If I make a dramatic styling change in the theme file then it has no effect. If I then comment the main CSS file, the theme CSS does have effect. Was I too naive in expecting this to work like this? I know I can use inline styles to overrule anything, but I prefer a setup like this if possible.
