  • Setting minOccurs="0" (required) on web service parameters of type int

    - by Alex Angas
    I have an ASP.NET 2.0 web method with the following signature: [WebMethod] public QueryResult[] GetListData( string url, string list, string query, int noOfItems, string titleField) I'm running the disco.exe tool to generate .wsdl and .disco files from this web service for use in SharePoint. The following WSDL for the parameters is being generated: <s:element minOccurs="0" maxOccurs="1" name="url" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="list" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="query" type="s:string" /> <s:element minOccurs="1" maxOccurs="1" name="noOfItems" type="s:int" /> <s:element minOccurs="0" maxOccurs="1" name="titleField" type="s:string" /> Why does the int parameter have minOccurs set to 1 instead of 0 and how do I change it? I've tried using [XmlElementAttribute(IsNullable=false)] in the parameter declaration without success.

  • What are Android different screens dimensions in dp for different screens (e.g. xlarge = 960dp x 720dp)?

    - by Zizo
    in this link: Range of screens supported, Android team mentioned that: As you design your UI for different screen sizes, you'll discover that each design requires a minimum amount of space. So, each generalized screen size above has an associated minimum resolution that's defined by the system. These minimum sizes are in "dp" units—the same units you should use when defining your layouts—which allows the system to avoid worrying about changes in screen density. xlarge screens are at least 960dp x 720dp large screens are at least 640dp x 480dp normal screens are at least 470dp x 320dp small screens are at least 426dp x 320dp So, If I want to support all Android screens, can I create images, for full screen view, in those dimensions and that will be sufficient condition to support all available screens? or they are just the minimum sizes, and I need other dimensions? If other dimensions are needed, Please list them as in the list above. Thanks in Advance.

  • Programmatically create static arrays at compile time in C++

    - by Hippicoder
    One can define a static array at compile time as follows: const std::size_t size = 5; unsigned int list[size] = { 1, 2, 3, 4, 5 }; Question 1 - Is it possible by using various kinds of metaprogramming techniques to assign these values "programmatically" at compile time? Question 2 - Assuming all the values in the array are to be the same barr a few, is it possible to selectively assign values at compile time in a programmatic manner? eg: const std::size_t size = 7; unsigned int list[size] = { 0, 0, 2, 3, 0, 0, 0 }; Solutions using C++0x are welcome The array may be quite large, few hundred elements long The array for now will only consist of POD types It can also be assumed the size of the array will be known beforehand, in a static compile-time compliant manner. Solutions must be in C++ (no script or codegen based solutions)

  • Abstract classes in shared library

    - by JTom
    Hi, I have an ordinary abstract class that has couple of pure virtual methods. The class itself is a part of the shared library. The compilation of the shared library itself is OK. But when the library is linked to another program that has another class deriving from the abstract one in the shared library and defining the pure virtual methods, I get the following linker error: I compile like this..: g++ -I../path/to/the/library main.cpp derived.cpp -L../path/to/the/library -lsomename -o shared ...and the linker error is: libsomename.so: undefined reference to `AbstractClass::method()' It's like the abstract class cannot access its pure virtual methods but I do not try to make any instance of the abstract class anywhere in the library. What could be the problem?

  • I have to select the checkbox two times to check/uncheck in jTable

    - by 117526709403775781607
    I have a jTable code i intend to use, but the problem with it is that when i click on the checkbox once it doesn't select/deselect it, instead i have to click twice. But if i select any other cell in the row except the one containing the checkbox the purpose is solved. HERE IS MY CODE : public class TableSelectionTest extends JFrame implements ListSelectionListener { private final int COLUMN_COUNT = 5; private TblModel model; public TableSelectionTest() { initialize(); setDefaultCloseOperation(EXIT_ON_CLOSE); pack(); } private void initialize() { List data = new ArrayList(); for (int i = 0; i < 10; i++) { Object record[] = new Object[COLUMN_COUNT]; record[0] = Boolean.FALSE; for (int j = 1; j < COLUMN_COUNT; j++) { record[j] = new Integer(j); } data.add(record); } model = new TblModel(data); JTable table = new JTable(model); table.getSelectionModel().setSelectionMode(ListSelectionModel.SINGLE_SELECTION); table.getSelectionModel().addListSelectionListener (this); JScrollPane scroll = new JScrollPane(table); getContentPane().add(scroll, BorderLayout.CENTER); } public static void main(String[] args) { TableSelectionTest f = new TableSelectionTest(); f.show(); } class TblModel extends AbstractTableModel { private List data; public TblModel(List data) { this.data = data; } public int getColumnCount() { return COLUMN_COUNT; } public int getRowCount() { return data == null ? 0 : data.size(); } public void setValueAt(Object value, int rowIndex, int columnIndex) { getRecord(rowIndex)[columnIndex] = value; super.fireTableCellUpdated(rowIndex, columnIndex); } public Object getValueAt(int rowIndex, int columnIndex) { return getRecord(rowIndex)[columnIndex]; } public boolean isCellEditable(int rowIndex, int columnIndex) { if(columnIndex == 0) return true; else return false; } public Class getColumnClass(int columnIndex) { if (data == null || data.size() == 0) { return Object.class; } Object o = getValueAt(0, columnIndex); return o == null ? Object.class : o.getClass(); } private Object[] getRecord(int rowIndex) { return (Object[]) data.get(rowIndex); } } public void valueChanged(ListSelectionEvent e) { if (!e.getValueIsAdjusting()) { ListSelectionModel lsm = (ListSelectionModel) e.getSource(); int index = lsm.getMinSelectionIndex(); if(model.getRecord(index)[0] == Boolean.FALSE) model.setValueAt(Boolean.TRUE, index, 0); else if(model.getRecord(index)[0] == Boolean.TRUE) model.setValueAt(Boolean.FALSE, index, 0); } } } Please reply soon as it is bugging me a lot Thank you in advance :)

  • Multiple checkbox values search javascript

    - by JV10
    I have a list of keywords, and I've created a checkbox for each. My template has a form wrapping the content, so I can't have a nested form around the checkbox list. How can I send the selected checkbox values to my search results page? The form that wraps the content doesn't have any actions or methods applied: <form id="BoostMasterForm" runat="server"> This the HTML markup of my checkbox list: <div class="checkboxes"> <ul> <li> <input type="checkbox" name="search" class="options" value="one"> <label>one</label> </li> <li> <input type="checkbox" name="search" class="options" value="two"> <label>two</label> </li> <li> <input type="checkbox" name="search" class="options" value="three"> <label>three</label> </li> </ul> <input type="submit" value="Submit"/> </div> How can I use javascript or jQuery to submit the values of the multiple checkbox selections and on submit action them to the following URL: '/imagery/image-search.aspx' The resulting URL for a search where option 1 and 3 are submitted should be: '/imagery/image-search.aspx?search=one%20three' I'm using this javascript that I found on another post, however I need it to append the form an the action and the method. My website is ASP, where this post is for a PHP site: Sending multiple checkbox options $('.options').click(function() { var selectedItems = new Array(); $(".checkboxes input:checkbox[name=search]:checked").each(function() {selectedItems.push($(this).val());}); var data = selectedItems.join('|'); $("#opts").val(data); }); If anyone can help, it'd be greatly appreciated.

  • Sending changing params through periodically_call_remote

    - by seaneshbaugh
    I'm using periodically_call_remote to update a portion of a page that contains a list of objects. I send along with the url a param containing the created_at date for the most recent object in the database. The action that is called then get all the objects that have been created since then and renders a partial which displays them at the top of the list. The problem is that I can't seem to figure out how to make it so that the next time periodically_call_remote triggers it sends along the created_at date for the new most recent object (if there is one). I tried putting the periodically_call_remote inside the partial that is being rendered but that caused all sorts of problems (http://www.ruby-forum.com/topic/101614 explains why you shouldn't do that). Is there some way I can make periodically_call_remote send along a new param each time it's called? As it stands right now it just sends the same one over and over which means that new objects get rendered more than once.

  • Select columns from join table only without requiring a join

    - by Kent Boogaart
    Given these tables: create table Orders ( Id INT IDENTITY NOT NULL, primary key (Id) ) create table Items ( Id INT IDENTITY NOT NULL, primary key (Id) ) create table OrdersItems ( OrderId INT not null, ItemId INT not null, primary key (OrderId, ItemId) ) Is it possible to use HQL/criteria API to contruct a query that results in the following SQL: SELECT [OrderId], [ItemId] FROM [OrdersItems] I've tried both of these approaches: var hqlResults = session .CreateQuery("select order.id, item.id from Order order inner join order.Items item") .List(); var criteriaResults = session .CreateCriteria<Order>() .CreateAlias("Items", "item", NHibernate.SqlCommand.JoinType.None) .SetProjection(Projections.Property("id"), Projections.Property("item.id")) .List(); But both approaches insist on generating a join (or fail because the join isn't present, in using criteria), resulting in SQL such as: select order.Id, item.Id from Orders order inner join OrdersItems ordersItems on order.Id = ordersItems.ArticleId inner join Items item on ordersItems.CategoryId = item.Id Is there any way to have NHibernate generate a query that selects columns only from the join table, without requiring a join?

  • What is the typical method to separate connected letters in a word using OCR

    - by Maysam
    I am very new to OCR and almost know nothing about the algorithms used to recognize words. I am just getting familiar to that. Could anybody please advise on the typical method used to recognize and separate individual characters in connected form (I mean in a word where all letters are linked together)? Forget about handwriting, supposing the letters are connected together using a known font, what is the best method to determine each individual character in a word? When characters are written separately there is no problem, but when they are joined together, we should know where every single character starts and ends in order to go to the next step and match them individually with a letter. Is there any known algorithm for that?

  • C# event or delegate or other solution?

    - by user295734
    Looking for some help or programmng ideas or mayeb there is some pattern that would help. Have an application that needs to fire alot of events sequentially, it could up to 100 or more unique events, it will be dynamic depeneding on the situation. Trying to find the best practice for doing this. My main idea right now is to create a list of objects iterate thru them, and fire each event. This seems wrong, or bad practice. Or maybe have one object and pass a list or params into one event? Or am I missing some feature in .NET that i could be using or implementing?

  • ignore certain buffers using iswitchb

    - by robUK
    Hello, GNU Emacs 23.1 I am using iswitchb. However, when I press c-x b I get a list of buffers. However, I don't want to display one like scratch, Messages, GNU Emacs, etc. Just the buffers I have opened myself. So I am looking for a way to ignore these buffers. This is what I have in my configuration. However, it doesn't ignore the buffers I don't want. Have I done anything wrong? ;; Setup iswitchb to select different buffers, ignore buffers to reduce list (iswitchb-mode 1) (setq iswitchb-buffer-ignore '("*scratch*")) (setq iswitchb-buffer-ignore '("*Messages*")) (setq iswitchb-buffer-ignore '("*GNU Emacs*")) (setq iswitchb-buffer-ignore '("*compilation*")) Many thanks for any suggestions,

  • Get ExternalInterface definitions in Javascript

    - by Jamal Fanaian
    Is there a way to get a list of the exposed functions from a Flash object? For example, you could get a list of all methods in an object by executing: for (var i in object) { if (typeof object[i] == "function") { console.log(i); } } The only issue is that this won't expose any methods registered through the ExternalInterfaces API. I can try and see if the function exists (object['method']) and it tells me it is a function, but I would have to guess every existing method in this manner. NOTE: Obviously, I don't have access to the actionscript.

  • Memory Leak with Swing Drag and Drop

    - by tom
    I have a JFrame that accepts top-level drops of files. However after a drop has occurred, references to the frame are held indefinitely inside some Swing internal classes. I believe that disposing of the frame should release all of its resources, so what am I doing wrong? Example import java.awt.datatransfer.DataFlavor; import java.io.File; import java.util.List; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.TransferHandler; public class DnDLeakTester extends JFrame { public static void main(String[] args) { new DnDLeakTester(); //Prevent main from returning or the jvm will exit while (true) { try { Thread.sleep(10000); } catch (InterruptedException e) { } } } public DnDLeakTester() { super("I'm leaky"); add(new JLabel("Drop stuff here")); setTransferHandler(new TransferHandler() { @Override public boolean canImport(final TransferSupport support) { return (support.isDrop() && support .isDataFlavorSupported(DataFlavor.javaFileListFlavor)); } @Override public boolean importData(final TransferSupport support) { if (!canImport(support)) { return false; } try { final List<File> files = (List<File>) support.getTransferable().getTransferData(DataFlavor.javaFileListFlavor); for (final File f : files) { System.out.println(f.getName()); } } catch (Exception e) { e.printStackTrace(); } return true; } }); setDefaultCloseOperation(DISPOSE_ON_CLOSE); pack(); setVisible(true); } } To reproduce, run the code and drop some files on the frame. Close the frame so it's disposed of. To verify the leak I take a heap dump using JConsole and analyse it with the Eclipse Memory Analysis tool. It shows that sun.awt.AppContext is holding a reference to the frame through its hashmap. It looks like TransferSupport is at fault. What am I doing wrong? Should I be asking the DnD support code to clean itself up somehow? I'm running JDK 1.6 update 19.

  • How to play 24 fps video smoothly on a 60Hz display? (or which player supports frame interpolation?)

    - by netvope
    I use mpc-hc to play videos on Win7 x64. With the default settings (#1), video playback is great most of the time. But for panning shots, playback is not smooth. I stepped through the video frame by frame and found that the panning movement is smooth (e.g. each frame shifts horizontally by 10 pixels), so the problem is how the 23.976 fps video is interpolated to 60Hz. The judder looks like what would be caused by a "2:3 pulldown", where the frames are played unevenly like: frame 1, 1, 2, 2, 2, 3, 3, 4, 4, 4, etc (#2) Using "optimal renderer settings" (#3) instead of the default disables the Aero theme and causes tearing. Setting my LCD display to 50Hz may have improved the judder slightly (but I can't really tell). My display does not support 24Hz or 48Hz, and forcing them in the Nvidia control panel gives blurry screen. I've tried other video players (VLC and KMPlayer), the ReClock Directshow Filter, video files from different sources (#4), turning on/off DXVA, and a computer with a different GPU, but the judder in the playback is similar. None of them solved the problem. So, how can I play 23.976 or 24 fps video smoothly on a 60Hz display? I think a video player could make the video smoother by doing linear interpolation, such as: 1. 100% frame 1 2. 60% frame 1 + 40% frame 2 3. 20% frame 1 + 80% frame 2 4. 80% frame 2 + 20% frame 3 5. 40% frame 2 + 60% frame 3 6. 100% frame 3 7. 60% frame 3 + 40% frame 4 .. etc Can any existing video player do this? Footnotes: (#1) Video renderer: EVR Custom Pres. (#2) This example converts a 24 fps video into 30 fps (#3) View Renderer settings Reset Reset to optimal renderer settings (#4) The files I have are all H.264 mkv files, but I don't think the file format/encoding matters.

  • Why does sh/bash set command line parameter values when trying to set environment variable?

    - by Touko
    A question on basics : While tuning environment variables for a program launched from a script, I ended up with somewhat strange behaviour with sh (which seems to be actually linked to bash) : variable setting seems to mess up with command-line parameters. Could somebody explain why does this happen? A simple script: #! /bin/sh # Messes with $1 ?? set ANT_OPTS=-Xmx512M export ANT_OPTS # Works # export ANT_OPTS=-Xmx512M echo "0 = $0" echo "1 = $1" When I run this with the upper alternative (set + export), the result is as following: $ ./test.sh foo 0 = ./test.sh 1 = ANT_OPTS=-Xmx512M But with lower alternative (export straight), the result is as I supposed: $ ./test.sh foo 0 = ./test.sh 1 = foo There is surely logical explanation, I just haven't figured it out yet. Somebody who does have idea? br, Touko

  • 2-byte (UCS-2) wide strings under GCC

    - by Seva Alekseyev
    Hi all, when porting my Visual C++ project to GCC, I found out that the wchar_t datatype is 4-byte UTF-32 by default. I could override that with a compiler option, but then the whole wcs* (wcslen, wcscmp, etc.) part of RTL is rendered unusable, since it assumes 4-byte wide strings. For now, I've reimplemented 5-6 of these functions from scratch and #defined my implementations in. But is there a more elegant option - say, a build of GCC RTL with 2-byte wchar-t quietly sitting somewhere, waiting to be linked? The specific flavors of GCC I'm after are Xcode on Mac OS X, Cygwin, and the one that comes with Debian Linux Etch.

I thought that maybe I could do something with a custom resolver but can't seem to figure out how.

  • Surface Detection in 2d Game?

    - by GamiShini
    I'm working on a 2D Platform game, and I was wondering what's the best (performance-wise) way to implement Surface (Collision) Detection. So far I'm thinking of constructing a list of level objects constructed of a list of lines, and I draw tiles along the lines. ( http://img375.imageshack.us/img375/1704/lines.png ). I'm thinking every object holds the ID of the surface that he walks on, in order to easily manipulate his y position while walking up/downhill. Something like this: //Player/MovableObject class MoveLeft() { this.Position.Y = Helper.GetSurfaceById(this.SurfaceId).GetYWhenXIs(this.Position.X) } So the logic I use to detect "droping/walking on surface" is a simple point (player's lower legs)-touches-line (surface) check (with some safety approximation - let`s say 1-2 pixels over the line). Is this approach OK? I`ve been having difficulty trying to find reading material for this problem, so feel free to drop links/advice.

  • Silverlight Isolated Storage and loading big files

    - by Thomas Joulin
    In a Windows Phone 7 application, I would like to query a big XML file (list of cities) stored using Isolated Storage. If I do that this way, will the file be loaded to memory ( 5 mo) ? If so, what other solution do I have? Edit: More details. I want to use AutoCompleteBox (http://www.jeff.wilcox.name/2008/10/introducing-autocompletebox/), but instead of using a web service (this is fixed data, no need to be online), I want to query a file/database/isolated storage... I have a fixed list of cities. I said in the comments it's 40k, but it finally seems closer to 1k rows.

  • Deleting a Collection with NHibernate Using the Criteria API

    - by lomaxx
    I think I know what the answer to this question is probably going to be, but I thought I'd go ahead and ask it anyway. It appears that within NHibernate if I do something like this: IList<Customer> customers = Session.CreateCriteria(typeof(Customer)) .Add(Restrictions.Eq("Name", "Steve") .List<Customer>(); And I want to then delete that list of customers. From what I can tell the only way to do it is like this: foreach(var customer in customers) { Session.Delete(customer); } But what I'm wondering is if there's any way I can just go: Session.Delete(customers); And delete the entire collection with a single call?

  • Explicitly multiplying values as longs

    I understand that all math is done as the largest data type required to handle the current values but when you transverse a loop how do you explicitly multiply longs? The following code returns 0, I suspect, because of an overflow. long result = 0L; List<Long> temp = (List<Long>) getListOfIntegers(); for (int i = 0; i < temp.size(); i++) { result *= temp.get(i).longValue(); } System.out.println(result);
