  • How to create a drop down menu like the one displayed on Amazon?

    - by webdev_newbee
    I am kind of new to web development. I am trying to create a drop down menu, something I have now is like: <select> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="opel">Opel</option> <option value="audi">Audi</option> </select> but this is not exactly what I want. I want to create a drop down list very similar to the one on Amazon.com (the dropdown list beside "Search"), shown in following pic. so whenever user click on the button, the list will be displayed in the button as text. Please feel free to give me any ideas. Thank you,

  • Stop node containing subnodes and text in schema

    - by AndyC
    If I have some xml like this: <mynode> <mysubnode> <mysubsubnode>hello world</mysubsubnode> some more text </mysubnode> </mynode> As you can see, mysubnode contains both a subnode and some text data. What I want to know is, is it possible to prevent this happening in a schema? I don't want nodes to contain subnodes and text, just subnodes or text. Is there an option in my xsd I can specify to force this? My program to that uses this xml is written in .NET, so I'll tag it as well incase there's anything of use in .net that I can utilise for this, though I'd much rather that the issue was fixed in the schema itself. Cheers

  • Python - read numbers from text file and put into list

    - by user1647372
    So like the title says im starting to learn some python and im having trouble picking up on this technique. What I need to accomplish is to read in some numbers and store them in a list. The text file looks like the following: 0 0 3 50 50 100 4 20 Basically these are coordinates and directions to be used for python's turtle to make shapes. I got that part down the only problem is getting them in a correct format. So what I can not figure out is how to get those numbers from the file into [ [0, 0, 3, 50], [50, 100, 4, 20] ] A list, with each four coordinates being a list in that one big list. Heres my attempt but it as I said I need some help - thank you. polyShape=[] infile = open(name,"r") num = int(infile.readline(2)) while num != "": polyShape.append(num) num = int(infile.readline(2)) infile.close()

  • Stop $_POST from having the same value when I refresh

    - by Cortopasta
    When a vote value is changed, the form POSTs the change, then refreshes the page. This is called on the top of the page upon load: if (isset($_POST['q'.$question_id])) { $user->updateQuestionVotes($question_id, $_POST['q'.$question_id]); } Why does it update every time I refresh after the first time? Do I need to unset it somehow?

  • Overlapping elements stop overlapping in IE7 on class change

    - by Gazzer
    On this page http://zenchan.com/program/ When I rollover the right box 2nd from the top suddenly the overlapping (negative margin disappears). What's happening is that a 'hover' class is being added to shift the background sprite. The two yellow boxes are debugging: if the hover class is put their in advance there is no problem. So fundamentally the CSS is not a problem for IE7 but adding the class is. Any ideas what's causing this. I've tried adding haslayout to various elements but to little effect.

  • Stop an input field in a form from being submitted

    - by Acorn
    I'm writing some javascript that will insert some input fields into a form on a website. The thing is, I don't want those input fields to affect the form in any way, I don't want them to be submitted when the form is submitted, I only want my javascript to have access to their values. Is there some way I could add some input fields into the middle of a form and not have them submitted when the form is submitted? Obviously the ideal thing would be for the input fields to not be in the form element, but I want the layout of my resulting page to have my inserted input fields appear between elements of the original form.

  • Efficient retrieval of lists over WebServices

    - by Chris
    I have a WCF WebService that uses LINQ and EF to connect to an SQL database. I have an ASP.NET MVC front end that collects its data from the webservice. It currently has functions such as List<Customer> GetCustomers(); As the number of customers increases massively the amount of data being passed increases also reducing efficiency. What is the best way to "page data" across WebServices etc. My current idea is to implement a crude paging system such as List<Customer> GetCustomers(int start, int length); This, however, means I would have to replicate such code for all functions returning List types. It is unfortunate that I cannot use LINQ as it would be much nicer. Does anyone have any advice or ideas of patterns to implement that would be "as nice as possible" Thanks

  • Stop Entity Framework from updating edmx model with a column that isn't needed

    - by TMan
    I have rowguids in all my tables to help with change tracking in all my tables. I don't want/need these tables in my edmx or my entities. However, I do still need to make changes to other things sometimes so everytime i go to update model from database in the edmx it adds all the rowguids in all my tables everytime and i have to manually delete each one. Is there a way to handle this from happening? Is there a way I can maybe edit the T4 to maybe ignore that 'rowguid' column? Database first Entity framework

  • c# 3.5 class List<int> class initialisation

    - by josephj1989
    I can initialize a List like new List{1,2,3,4,5}; However List does not have a constructor which accepts a single parameter. So I tried to run this through the debugger and it seems to be calling the Add method. So how does the compiler know which method to invoke to add each individual element. This may be a silly question but I am a bit confused. Thanks

Thanks.

  • Choosing randomly all the elements in the the list just once

    - by Dalek
    How is it possible to randomly choose a number from a list with n elements, n time without picking the same element of the list twice. I wrote a code to choose the sequence number of the elements in the list but it is slow: >>>redshift=np.array([0.92,0.17,0.51,1.33,....,0.41,0.82]) >>>redshift.shape (1225,) exclude=[] k=0 ng=1225 while (k < ng): flag1=0 sq=random.randint(0, ng) while (flag1<1): if sq in exclude: flag1=1 sq=random.randint(0, ng) else: print sq exclude.append(sq) flag1=0 z=redshift[sq] k+=1 It doesn't choose all the sequence number of elements in the list.

  • More elegant way to initialize list of duplicated items in Python

    - by Claudiu
    If I want a list initialized to 5 zeroes, that's very nice and easy: [0] * 5 However if I change my code to put a more complicated data structure, like a list of zeroes: [[0]] * 5 will not work as intended, since it'll be 10 copies of the same list. I have to do: [[0] for i in xrange(5)] that feels bulky and uses a variable so sometimes I even do: [[0] for _ in " "] But then if i want a list of lists of zeros it gets uglier: [[[0] for _ in " "] for _ in " "] all this instead of what I want to do: [[[0]]*5]*5 Has anyone found an elegant way to deal with this "problem"?

  • MS Access Dropdown List/Combo Box

    - by noblethrasher
    This should probably be pretty simple but my Google-Fu is as yet unable to find an answer. I simply want to create a dropdown list in Access so that upon selection I can perform some action based on the value of the selection. For instance, I have a list of people and I would like to populate the combo box so that their names appear in the list but the "value" is set to their ID (the primary key).

  • Displaying a list of items vertically in a table instead of horizonally

    - by MichaelMM
    I have a list of items sorted alphabetically: list = [a,b,c,d,e,f,g,h,i,j] I'm able to output the list in an html table horizonally like so: | a , b , c , d | | e , f , g , h  | | i  , j  ,    ,     | What's the algorithm to create the table vertically like this: | a , d , g , j | | b , e , h ,   | | c , f  ,  i  ,  | I'm using python, but your answer can be in any language or even pseudocode. Thanks

  • ListSelector applies to the entire list

    - by jax
    I have a simple list with a listselector like so. <ListView android:id="@+id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_below="@+id/round" android:listSelector="#99000000" android:clickable="true" android:cacheColorHint="#00000000" android:background="#00000000"> </ListView> As you can see android:listSelector="#99000000" but the "black alpha" color is applied to the entire list, not the selected item. So this is what I have now but the entire list still turns black ::listview_background.xml <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_enabled="false" android:state_focused="true" android:drawable="@drawable/list_normal" /> <item android:state_pressed="true" android:drawable="@drawable/list_pressed" /> <item android:state_focused="true" android:drawable="@drawable/list_active" /> </selector> ::colors.xml <resources> <drawable name="list_normal">#96FFFFFF</drawable> <drawable name="list_active">#66000000</drawable> <drawable name="list_pressed">#CA000000</drawable> </resources> ::the xml tag in my list android:listSelector="@drawable/listview_background"

  • QT List of Callbacks

    - by Talguy
    I am trying to make a real-time data collection application that has timed task. Each task can have a different or the same update period. I would like to store the task with the common update period in a list where I can iterate through it and call the function that I registered in the list. How would I go about adding callbacks to a data structure like a list or vector? Can I store slots in them?

  • Allow users to enter a variable length list of items in asp.net form

    - by EJB
    I need to let my users enter a variable length list of items into something that looks like a grid view (or a series of standard text boxes stacked vertically). Each item could be a few characters or a few hundred characters long, and I just want them to enter a "sentence", and then tab to the next row, and always having another blank one ready to go at the bottom of the list. I don't want to save any data to my SQL Server DB until they enter the entire list and then click on a "save all" button. When they hit the "save all" button they will be given a preview screen where the data will be presented as standard HTML ordered list. If they confirm/save, then each row of the grid will then be saved as a separate row into my SQL Server database (with an index to remember the order). What ASP.Net (or Jquery/javascript) UI control would be the best to use in this situation?
