  • dymanic columns in mysql tables?

    - by fayer
    i want to add dynamic columns in a mysql table. but i dont know exactly how. i want to let the user add some columns (fields) in a thread. eg. let him add a integer field and a value (eg. price: 199) or a string field and a value (eg. name: teddybear). the user can add as many field/value-pairs as he wants. i thought i could create a many-to-many table: thread <- thread_field <- field thread: id, title thread_field: field_id, thread_id, value field: id, name is this a good structure? but in this way i have to set a specific column type of thread_field.value. either its an integer or a string. i want to have the possibility to have it dymanic, let the user choose. how can i do this? thanks!

  • Touch Screen Product Catalog for Retail Store

    - by Patrick
    I am a UI/UX designer and I would like to create kiosk type of app that would be a product catalog (help/suggestor) for customers in a retail store using a touch screen monitor (and computer). Something as simple as this: http://www.youtube.com/watch?v=aoH0u6YTTK4 This is what I would like it to do: 1st Screen (Main Menu): Pick a type of category (For example: Dog, Cat, Small Animal) 2nd Screen pick a sub-category of a main category (For example: Puppy, Adult, Senior - DOG) 3rd Screen pick a sub-category of previous sub-category (For example: Food, Healthy, Toys) Then it will display a list of all products with a picture, small description, and price. Thats it. So the point of the kiosk is to help customers find certain products that match their pet criteria. (Dog Puppy Healthy Dog Food) I am wondering what is the best solution: RIA (Flex/Air or Silveright) or flash/action script. I am not sure what is the best technology to use for the following benefits: user-experience (smoothness of touch screen actions) and fast development.

  • Looking for a new PHP website framework

    - by Glycerine
    I built many a website, and my own 'custom' framework is just a general box of scripts cobbled together with loose ideas. I would love to progress to a framework which allows me to pass it onto the client for freedom. Someone suggested using wordpress but I'm not sure how general this can be. A current site I need to build is a fancy kitchen company, price lists, flash gallery (with backend driven pics) and well designed home. How could I bend the the will of wordpress? Alternatively, does anyone have a suggestion for an alternative. Thanks in advance guys -

  • My iPhone app has been downloaded by people all over the world, but has no use to anyone outside of

    - by Rob Lourens
    I wrote a basic free app for the bus schedule in my American university's town which was accepted into the app store on Saturday. Since then the app has been downloaded (assuming I'm reading the iTunes Connect reports right) 18 times in Canada, 6 times in Germany, and many times from other places all over the world. I can't figure out why all these people are downloading it... are there services automatically downloading free apps for some purpose that I can't even imagine? Should I put a price on it ASAP?

  • How can I refer to a binding converter in another namespace in Silverlight XAML?

    - by Mike Pateras
    Since you apparently can't create a Silverlight DataTemplate in C#, I'm trying to create one in XAML. I have a converter that I need to refer to, that I have defined in C# in another namespace. I've tried doing this: <UserControl.Resources> <DataTemplate x:Key="PriceTemplate"> <TextBlock Text="{Binding Price, Converter={Converters:PriceConverter}}" /> </DataTemplate> </UserControl.Resources> Where Converters is an xmlns that points to the correct namespace. However, I get a compilation error that says: Type 'Converters:PriceConverter' is used like a markup extension but does not derive from MarkupExtension. I tried adding System.Windows.Markup.MarkupExtension as a parent to my converter, but it apparently doesn't exist in Silverlight. How can I refer to my converter in XAML, without having to rewrite it in XAML?

  • How do would you use jQuery's .each() to apply the same script to each element with the same class?

    - by derekmx271
    I have a with multiple cart items listed. I have a "x-men logo" looking remove button that I want to fade-in next to the item when the customer hovers over a cart item. I had no issue getting this to work when there is only one item in the list. However, when there are multiple items in the cart, the jQuery operates funky. It still does the fade in, but only when I hover over the last item in the cart, and of course all of the "remove X" images become visible. Argh... So i searched around and think the .each() is my savior. I have been trying to get it to work, with no luck. My script just breaks when I attempt to implement it. Anyone have any pointers on this *.each() thing and how to implement it into my script?* I have tried putting a cartItem.each(function(){ around the mouseEnter/mouseLeave events (and used some $(this) selectors to make it "make sense") and that didn't do anything. Tried some other things as well with no luck... Here is the HTML (Sorry, there's a lot): <ul id="head-cart-items"> <!-- Item #1 --> <li> <!-- Item #1 Wrap --> <div class="head-cart-item"> <div class="head-cart-img" style='background-image:url("/viewimageresize.asp?mh=50&amp;mw=50&amp;p=AFE&amp;f=Air_Intakes_Magnum_FORCE_Stage-1_PRO_5R")'> </div> <div class="head-cart-desc"> <h3> <a href="/partdetails/AFE/Intakes/Air_Intakes/Magnum_FORCE_Stage-1_PRO_5R/19029">AFE Magnum FORCE Stage-1 PRO 5R Air Intakes</a> </h3> <span class="head-cart-qty">Qty: 1</span> <span class="head-cart-price">$195.00</span> <!-- Here is my Remove-X... --> <a class="remove-x" href='/cart//7806887'> <img src="/images/misc/remove-x.png"> </a> </div> </div> </li> <!-- Item #2 --> <li> <!-- Item #2 Wrap --> <div class="head-cart-item"> <div class="head-cart-img" style='background-image:url("/viewimageresize.asp?mh=50&amp;mw=50&amp;p=Exedy&amp;f=Clutch_Kits_Carbon-R")'> </div> <div class="head-cart-desc"> <h3> <a href="/partdetails/Exedy/Clutch/Clutch_Kits/Carbon-R/19684">Exedy Carbon-R Clutch Kits</a> </h3> <span class="head-cart-qty">Qty: 1</span> <span class="head-cart-price">$2,880.00</span> <!-- Here is my other Remove-X... --> <a class="remove-x" href='/cart//7806888'> <img src="/images/misc/remove-x.png"> </a> </div> </div> </li> </ul> And here is the jQuery... $(document).ready(function(){ var removeX = $(".remove-x"); var cartItem = $(".head-cart-item"); // Start with an invisible X removeX.fadeTo(0,0); // When hovering over Cart Item cartItem.mouseenter(function(){ // Fade the X to 100% removeX.fadeTo("normal",1); // On mouseout, fade it back to 0% $(this).mouseleave(function(){ removeX.fadeTo("fast",0); }); }); }); If you didn't see it, here is the "X" I am trying to fade... <!-- Here is my Remove-X... --> <a class="remove-x" href='/cart//7806887'> <img src="/images/misc/remove-x.png"> </a> Thanks for the help in advance.

  • Selling an application both in the android market and outside it

    - by Lo'oris
    I understand it is possible to sell the same application both in the market and outside it, great. I still don't understand a few things, that AFAIK are not mentioned in the contract but I might have missed or misunderstood something, so I'm going to ask. Disclaimer: I know you're not a lawyer, etc. etc. Let's say I give in the market a demo version, and I sell in the market the full version too. May I also sell the full version outside the market? I understand that you can't give away the demo in the market and then collect the payment outside, but what if I do allow the user to buy it in the market, but also allow him to buy outside the market? What if I charge a lower price if he buys outside the market?

  • Symfony: Pass an object from another module to a form

    - by djcloud23
    I have a symfony project and I have one model, which for this example I will name Boat. From the Boat's showSuccess page, I would like to make a link to another model's form page. For this example we will call it Ticket. When they click on the link, I would like for the Boat object to be passed to the Ticket form because I have to display some of that specific Boat's fields (title, price, etc) on the Ticket form page (newSuccess.php). I guess my question is, how do I pass an object (as a variable) to another model's "new" form page. I have looked everywhere and I can't seem to find an answer that works for me. Thank you!

    I have created a table in ms access. I have set the data type of ID to Auto Number in MS-access.

  • What is the most efficient approach to fetch category tree, products, brands, counts by subcategory

  • Interactive Charts for web application

    - by user227290
    We are working on a web based application (implemented in JAVA) on commodity prices and one part of it is interactive charting. I provide a simplified example here. We have a table in Mysql database where we have information on commodity prices in US states and counties. One aspect of the application is to create interactive plots based on user choice. For example, if the user needs to see the price density in Oregon and Linn county then she chooses it from the menu in a webpage and it is rendered on fly with accompanying quantile information in a table. As the user changes state and county these plots and table change on fly.For our computational need we are using R (and use rjava to integrate it to our web application) and I know that if interactivity is not an issue this is a piece of cake in ggplot2, but I am not aware of any interactive version of R graphics framework (like lattice, ggplot2). We are exploring google visualization API but I am not sure we can have the statistical power we need in some of the plots.Please help.

  • What ever happened to Java and Sun?

    - by leeand00
    What happened to Java and Sun? The community surrounding them had some of my favorite tools and software to develop with. The Java platform anyway, still looked like it had some promise to it: Groovy and Grails. Why does all of this seem to be going the way of the dodo lately? (Yes, I know their stock price is dropping badly.) Is it just the economy? Or did the lack of cohesion (i.e., not settling on a framework) among the community finally lead to its demise?

  • need to changed markup with jquery

    - by user357034
    I have the following markup which I do not have direct access to... <a href="javascript:void(0);" onclick="window.open('/BulkDiscounts.asp?ProductID=318&ProductCode=' + escape('LB30X40ES') + '&Orig_Price=22.95', 'Discounts', 'scrollbars,status,resizable,width=330,height=300');"><iimg src="/v/vspfiles/templates/100/images/buttons/btn_quantitydiscounts.gif" border="0" align="absmiddle"></a> I need to "rewrite" the above as follows... A few things to point out is that the title is coming from a variable escape(global_Current_ProductCode) variable=productcode in the case above it is LB30X40ES The height and weight, price and product id used in the second markup must be from the first markup. Note that these change depending on the product loaded. These are not constants. I would guess the first thing to do was to add the thickbox class. Then I am lost as to what to do next. Basically I need to open up an thickbox iframe with the modified markup.

  • Ruby Metaprogramming

    - by Veerendra Manikonda
    I am having a method which returns the price of a given symbol and i am writing a test for that method. This is my test def setup @asset = NetAssetValue.new end def test_retrieve_price_for_symbol_YHOO assert_equal(33.987, @asset.retrieve_price_for_a_symbol('YHOO')) end def test_retrive_price_for_YHOO def self.retrieve_price_for_a_symbol(symbol) 33.77 end assert_equal(33.97, @asset.retrieve_price_for_a_symbol('YHOO')) end This is my method. def retrieve_price_for_a_symbol(symbol) symbol_price = { "YHOO" => 33.987, "UPS" => 35.345, "T" => 80.90 } raise Exception if(symbol_price[symbol].nil?) symbol_price[symbol] end I am trying to mock the retrieve_price_for_a_symbol method by writing same method in test class but when i call it, the call is happening to method in main class not in the test class. How do I add that method to meta class from test and how do i call it? Please help.

  • LINQ Expression help with Func TEntity,TType

    - by Chris Conway
    I have a repository method that accepts an order by parameter in the form: public IEnumerable<TEntity> Get<TEntity>(Expression<Func<TEntity,string>> orderBy) Now that works fine when trying to sort by a property of type string, var entities = rep.Get(x => x.Name); but what if i want to sort by double or int or any other type. Doing something like var entities = rep.Get(x => x.Price); obviously throws a compile error saying I can't convert double to string. How can I make this more generic so I can sort by any property in my entity, or at least the properties where the type implements IComparable or something similar?

  • Upsides of a timebox for a customer

    - by Ivo
    So I have a customer with a potential big project that (ofcourse) does not know what they want exactly. The size of this project can be more that 4 or 5 months so that is a big risk. Thats why I want to sell a timebox. For me that takes away the risk of spending 10 months instead of 5 for the same price. The problem is that I can't comeup with good arguments to convince the customer that a timebox is better for them. Any suggestions? How do you people handle this/

  • What's the best way to return something like a collection of `std::auto_ptr`s in C++03?

    - by Billy ONeal
    std::auto_ptr is not allowed to be stored in an STL container, such as std::vector. However, occasionally there are cases where I need to return a collection of polymorphic objects, and therefore I can't return a vector of objects (due to the slicing problem). I can use std::tr1::shared_ptr and stick those in the vector, but then I have to pay a high price of maintaining separate reference counts, and object that owns the actual memory (the container) no longer logically "owns" the objects because they can be copied out of it without regard to ownership. C++0x offers a perfect solution to this problem in the form of std::vector<std::unique_ptr<t>>, but I don't have access to C++0x. Some other notes: I don't have access to C++0x, but I do have TR1 available. I would like to avoid use of Boost (though it is available if there is no other option) I am aware of boost::ptr_container containers (i.e. boost::ptr_vector), but I would like to avoid this because it breaks the debugger (innards are stored in void *s which means it's difficult to view the object actually stored inside the container in the debugger)

  • How can I format numbers as money in JavaScript?

    - by Daniel Magliola
    I would like to format a price in JavaScript. Basically, I have a float variable, and I'd like to have a function that will receive that variable, and output: "$ 2,500.00" What's the best way to do this? EDIT: OK, since I haven't gotten any answers better than the code I implemented, plus my own answer has been voted down and I can't put my own answer as the right one... Here it is... var DecimalSeparator = Number("1.2").toLocaleString().substr(1,1); var AmountWithCommas = Amount.toLocaleString(); var arParts = String(AmountWithCommas).split(DecimalSeparator); var intPart = arParts[0]; var decPart = (arParts.length > 1 ? arParts[1] : ''); decPart = (decPart + '00').substr(0,2); return '£ ' + intPart + DecimalSeparator + decPart;
