  • Consecutive Tables in Latex

    - by Tim
    Hi, I wonder how to place several tables consecutively in Latex? The page with the text right before the first table has a little space but not enough for the first table, so the first table is to be placed on the top of the next page, although I use "\begin{table}[!h]" for it. The second table does not fit into the place in the rest of the page of the first table, so I think I might use longtable for it to span the rest of the page and the top of the next page. Similarly, I use longtable for the third table. The latex code is as follows: ... % some text \begin{table}[!h] \caption{Table 1. \label{tab:1}} \begin{center} \begin{tabular}{c c} ... \end{tabular} \end{center} \end{table} \begin{center} \begin{longtable}{ c c } \caption{Table 2. \label{tab:2}}\\ ... \end{longtable} \end{center} \begin{center} \begin{longtable}{ c c } \caption{Table 3. \label{tab:3}}\\ ... \end{longtable} \end{center} ... % some text In the compiled pdf file it turns out that the order of the tables is messed up. The first table is placed behind the second and third one, and the second one spans the page with text before the tables and the next page with the third one following it. I would like to know how I can make the three tables appear consecutively in order, and there are no space left blank between them and between the text and the tables? Or if what I hope is not possible, what is the best strategy then? Thanks and regards! EDIT: Removing [!h] does not make improvement, the first table is still behind the second and the third.

  • One to One XSLT map with namespace manipulations

    - by ohadinho
    I have the following xml: <ns0:Root xmlns:ns0="http://root" xmlns:nm="http://notroot"> <nm:MSH> <content>bla</content> </nm:MSH> <ns0:Second> <ns0:item>aaa</ns0:item> </ns0:Second> <ns0:Third> <ns0:itemb>vv</ns0:itemb> </ns0:Third> </ns0:Root> That is my expected result: <Root xmlns="http://root" xmlns:nm="http://notroot"> <nm:MSH> <content>bla</content> </nm:MSH> <Second> <item>aaa</item> </Second> <Third> <itemb>vv</itemb> </Third> </Root> I need to write an xslt 1.0 that perform that map. I really doesn't have a clue how to do it, thus it seems pretty simple. Can anyone please help ?

  • How to include many "sub"-queries in a SQL statement to generate file paths for images?

    - by Zachary
    Greetings, I have three fields in legacy MySQL database/application. image_type image_of_bush image_prefix I need to extract the data into a full image file path, into a .CSV file, where each combination (mentioned below) is a column. Can it all be done in SQL? Or can you recommend a better way? Currently using PHP to display the combinations on the product page. this is also part of a larger query, which is extracting data from an OS Commerce mySQL database. CASE ONE One Horizontal Image image_type = "Horizontal Image" image_of_bush = "No Image of Bush" IMAGE NAME: image_prefix + _s + .jpg (Example: Albertine_s.jpg) CASE TWO One Vertical Image image_type = "Vertical Image" image_of_bush = "No Image of Bush" IMAGE NAME: image_prefix + _v + .jpg (Example: Albertine_v.jpg) CASE THREE Two Horizontal Images image_type = "Horizontal Image" image_of_bush = "Horizontal Image of Bush" FIRST IMAGE NAME: image_prefix + _s + .jpg (Example: Albertine_s.jpg) SECOND IMAGE NAME: image_prefix + _bs + .jpg (Example: Albertine_bs.jpg) CASE FOUR Two Vertical Images image_type = "Vertical Image" image_of_bush = "Vertical Image of Bush" FIRST IMAGE NAME: image_prefix + _v + .jpg (Example: Albertine_v.jpg) SECOND IMAGE NAME: image_prefix + _bv + .jpg (Example: Albertine_bv.jpg) CASE FOUR One Horizontal and One Vertical Image image_type = "Horizontal Image" image_of_bush = "Vertical Image of Bush" FIRST IMAGE NAME: image_prefix + _s + .jpg (Example: Albertine_s.jpg) SECOND IMAGE NAME: image_prefix + _bv + .jpg (Example: Albertine_bv.jpg) CASE FIVE One Vertical and One Horizontal Image image_type = "Vertical Image" image_of_bush = "Horizontal Image of Bush" FIRST IMAGE NAME: image_prefix + _v + .jpg (Example: Albertine_v.jpg) SECOND IMAGE NAME: image_prefix + _bs + .jpg (Example: Albertine_bs.jpg)

  • Division by zero: Undefined Behavior or Implementation Defined in C and/or C++ ?

    - by SiegeX
    Regarding division by zero, the standards say: C99 6.5.5p5 - The result of the / operator is the quotient from the division of the first operand by the second; the result of the % operator is the remainder. In both operations, if the value of the second operand is zero, the behavior is undefined. C++03 5.6.4 - The binary / operator yields the quotient, and the binary % operator yields the remainder from the division of the first expression by the second. If the second operand of / or % is zero the behavior is undefined. If we were to take the above paragraphs at face value, the answer is clearly Undefined Behavior for both languages. However, if we look further down in the C99 standard we see the following paragraph which appears to be contradictory(1): C99 7.12p4 - The macro INFINITY expands to a constant expression of type float representing positive or unsigned infinity, if available; Do the standards have some sort of golden rule where Undefined Behavior cannot be superseded by a (potentially) contradictory statement? Barring that, I don't think it's unreasonable to conclude that if your implementation defines the INFINITY macro, division by zero is defined to be such. However, if your implementation does not define such a macro, the behavior is Undefined. I'm curious what the consensus on this matter for each of the two languages. Would the answer change if we are talking about integer division int i = 1 / 0 versus floating point division float i = 1.0 / 0.0 ? Note (1) The C++03 standard talks about the library which includes the INFINITY macro.

  • How to play simultaneous multiply audio sources in Silverlight

    - by Shurup
    I want to play simultaneous multiply audio sources in Silverlight. So I've created a prototype in Silverlight 4 that should play a two mp3 files containing the same ticks sound with an intervall 1 second. So these files must be sounded as one sound if they will be played together with any whole second offsets (0 and 1, 0 and 2, 1 and 1 seconds, etc.) I my prototype I use two MediaElement (me and me2) objects. DateTime startTime; private void Play_Clicked(object sender, RoutedEventArgs e) { me.SetSource(new FileStream(file1), FileMode.Open))); me2.SetSource(new FileStream(file2), FileMode.Open))); var timer = new DispatcherTimer { Interval = TimeSpan.FromMilliseconds(1) }; timer.Tick += RefreshData; timer.Start(); } First file should be played at 00:00 sec. and the second in 00:02 second. void RefreshData(object sender, EventArgs e) { if(me.CurrentState != MediaElementState.Playing) { startTime = DateTime.Now; me.Play(); return; } var elapsed = DateTime.Now - startTime; if(me2.CurrentState != MediaElementState.Playing && elapsed >= TimeSpan.FromSeconds(2)) { me2.Play(); ((DispatcherTimer)sender).Stop(); } } The tracks played every time different and not simultaneous as they should (as one sound).

  • What noncluster index would be better to create on SQL Server?

    - by Junior Mayhé
    Here I am studying nonclustered indexes on SQL Server Management Studio. I've created a table with more than 1 million records. This table has a primary key. SELECT CustomerName FROM Customers Which leads the execution plan to show me: I/O cost = 3.45646 Operator cost = 4.57715 For the first attempt to improve performance, I've created a nonclustered index for this table: CREATE NONCLUSTERED INDEX [IX_CustomerID_CustomerName] ON [dbo].[Customers] ( [CustomerId] ASC, [CustomerName] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] GO With this first try, I've executed the select statement and the execution plan shows me: I/O cost = 2.79942 Operator cost = 3.92001 Now the second try, I've deleted this nonclustered index in order to create a new one. CREATE NONCLUSTERED INDEX [IX_CategoryName] ON [dbo].[Categories] ( [CategoryId] ASC ) INCLUDE ( [CategoryName]) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] GO With this second try, I've executed the select statement and the execution plan shows me the same result: I/O cost = 2.79942 Operator cost = 3.92001 Am I doing something wrong or this is expected? Shall I use the first nonclustered index with two fields, or the second nonclustered with one field (CategoryID) including the second field (CategoryName)?

  • How to set a EditText in a certain column of a TableLayout?

    - by Nick
    I have a TableLayout on one Android Activity UI. It has two columns. Now I need to add a new row, and put an EditText box in second column of that new row. And also, I want that EditText full fill the whole cell. I have some code like this: TableRow tr = new TableRow(context); EditText et = new EditText(context); et.SetMaxLines(4); etText.setLayoutParams(new TableRow.LayoutParams(1)); //set it to the second coloumn tr.addView(et); tl.addView(tr); //tl is the tableLayout It puts the EditText in the second column fine, but the EditText is too small. I tried to use etText.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); but that seems to disabled the TableRow.LayoutParams setting. I guess each control can only have one LayoutParamas setting. So, how to make the EditText as a 4 lines text editor and also make sure it is in the second column of that row? Thanks.

  • Validating parameters according to a fixed reference

    - by James P.
    The following method is for setting the transfer type of an FTP connection. Basically, I'd like to validate the character input (see comments). Is this going overboard? Is there a more elegant approach? How do you approach parameter validation in general? Any comments are welcome. public void setTransferType(Character typeCharacter, Character optionalSecondCharacter) throws NumberFormatException, IOException { // http://www.nsftools.com/tips/RawFTP.htm#TYPE // Syntax: TYPE type-character [second-type-character] // // Sets the type of file to be transferred. type-character can be any // of: // // * A - ASCII text // * E - EBCDIC text // * I - image (binary data) // * L - local format // // For A and E, the second-type-character specifies how the text should // be interpreted. It can be: // // * N - Non-print (not destined for printing). This is the default if // second-type-character is omitted. // * T - Telnet format control (<CR>, <FF>, etc.) // * C - ASA Carriage Control // // For L, the second-type-character specifies the number of bits per // byte on the local system, and may not be omitted. final Set<Character> acceptedTypeCharacters = new HashSet<Character>(Arrays.asList( new Character[] {'A','E','I','L'} )); final Set<Character> acceptedOptionalSecondCharacters = new HashSet<Character>(Arrays.asList( new Character[] {'N','T','C'} )); if( acceptedTypeCharacters.contains(typeCharacter) ) { if( new Character('A').equals( typeCharacter ) || new Character('E').equals( typeCharacter ) ){ if( acceptedOptionalSecondCharacters.contains(optionalSecondCharacter) ) { executeCommand("TYPE " + typeCharacter + " " + optionalSecondCharacter ); } } else { executeCommand("TYPE " + typeCharacter ); } } }

  • Can you stop a defered callback in jquery 1.5?

    - by chobo2
    Hi I am wondering say you have something like this // Assign handlers immediately after making the request, // and remember the jqxhr object for this request var jqxhr = $.ajax({ url: "example.php" }) .success(function(response) { alert("success"); }) // perform other work here ... // Set another success function for the request above jqxhr.success(function(response){ alert("second success"); }); So I am thinking this. I have a general function that I want to use on all my responses that would be passed into my success. This function basically does a check to see if the server validation found any errors. If it did they it formats it and displays a message. Now I am wondering if I could some how have the second success function to then do specific stuff. Like say One ajax request needs to add a row into a table. So this should be possible. I just do what I have above and in the second success I just add the row. Is it possible though that if the first success runs through and see that there are validation errors from the server that I can stop the second success from happening? Sort of If(first success finds errors) { // print out errors // don't continue onto next success } else { // go to next success } Edit I found that there is something call deferred.reject and this does stop it but I am wondering how can I specify to stop only the success one. Since my thinking is if there are other deffered ones like complete on it will the be rejected too?

  • Reporting Services 2005 - Parameter reliant on cascading parameters

    - by sHr0oMaN
    Good day I have the following: In a SSRS 2005 report I have three report parameters: FinancialPeriodType ("Month" or "Week" in a DropDownList), FinancialPeriod (cascading DropDownList populated depending on first selection) and another parameter, OpeningBalance, of type float. The first two parameters are cascading i.e. the first parameter is used by the query populating the second's available values. This works fine. What I'm attemping to do is default the value of OpeningBalance to a value from a dataset populated by a stored procedure which takes in the first two parameters. However as soon as I select a value for the first parameter, I get the following error: An error occurred during report processing. The value for the report parameter 'OpeningBalance' is not valid for its type.' I've tried setting the default of the second parameter to be a meaningful default (something like 200901) as well as defaulting the second parameter in the SQL store procedure with no affect. Using SQL Profiler I've noticed that selecting a value for the first parameter doesn't even execute the SQL used to obtain available values for the second parameter.

  • Making two Windows using CreateWindowsEx()

    - by Jamie Keeling
    Hello, I have a windows form that has a simple menu and performs a simple operation, I want to be able to create another windows form with all the functionality of a menu bar, message pump etc.. as a separate thread so I can then share the results of the operation to the second window. I.E. 1) Form A opens Form B opens as a separate thread 2)Form A performs operation 3)Form A passes results via memory to Form B 4)Form B display results I'm confused as to how to go about it, the main app runs fine but i'm not sure how to add a second window if the first one already exists. I think that using CreateWindow will allow me to make another window but again i'm not sure how to access the message pump so I can respond to certain events like WM_CREATE on the second window. I hope it makes sense. Thanks! Edit: I've attempted to make a second window and although this does compile, no windows show atall on build. ////////////////////// // WINDOWS FUNCTION // ////////////////////// LRESULT CALLBACK WindowFunc(HWND hMainWindow, UINT message, WPARAM wParam, LPARAM lParam) { //Fields WCHAR buffer[256]; struct DiceData storage; HWND hwnd; // Act on current message switch(message) { case WM_CREATE: AddMenus(hMainWindow); hwnd = CreateWindowEx( 0, "ChildWClass", (LPCTSTR) NULL, WS_CHILD | WS_BORDER | WS_VISIBLE, 0, 0, 0, 0, hMainWindow, NULL, NULL, NULL); ShowWindow(hwnd, SW_SHOW); break; Any suggestions as to why this happens?

  • How to take a collection of bytes and pull typed values out of it?

    - by Pat
    Say I have a collection of bytes var bytes = new byte[] {0, 1, 2, 3, 4, 5, 6, 7}; and I want to pull out a defined value from the bytes as a managed type, e.g. a ushort. What is a simple way to define what types reside at what location in the collection and pull out those values? One (ugly) way is to use System.BitConverter and a Queue or byte[] with an index and simply iterate through, e.g.: int index = 0; ushort first = System.BitConverter.ToUint16(bytes, index); index += 2; // size of a ushort int second = System.BitConverter.ToInt32(bytes, index); index += 4; ... This method gets very, very tedious when you deal with a lot of these structures! I know that there is the System.Runtime.InteropServices.StructLayoutAttribute which allows me to define the locations of types inside a struct or class, but there doesn't seem to be a way to import the collection of bytes into that struct. If I could somehow overlay the struct on the collection of bytes and pull out the values, that would be ideal. E.g. Foo foo = (Foo)bytes; // doesn't work because I'd need to implement the implicit operator ushort first = foo.first; int second = foo.second; ... [StructLayout(LayoutKind.Explicit, Size=FOO_SIZE)] public struct Foo { [FieldOffset(0)] public ushort first; [FieldOffset(2)] public int second; } Any thoughts on how to achieve this?

  • Pointing class property to another class with vectors

    - by jmclem
    I've got a simple class, and another class that has a property that points to the first class: #include <iostream> #include <vector> using namespace std; class first{ public: int var1; }; class second{ public: first* classvar; }; Then, i've got a void that's supposed to point "classvar" to the intended iteration of the class "first". void fill(vector<second>& sec, vector<first>& fir){ sec[0].classvar = &fir[0]; } Finally the main(). Create and fill a vector of class "first", create "second" vector, and run the fill function. int main(){ vector<first> a(1); a[0].var1 = 1000; vector<second> b(1); fill(b, a); cout << b[0].classvar.var1 << '\n'; system("PAUSE"); return 0; } This gives me the following error: 1>c:\...\main.cpp(29) : error C2228: left of '.var1' must have class/struct/union 1> type is 'first *' And I can't figure out why it reads the "classvar" as the whole vector instead of just the single instance. Should I do this cout << b[0].classvar[0].var1 << '\n'; it reads perfectly. Can anyone figure out the problem? Thanks in advance

  • Html image link, not working

    - by Anders Metnik
    Hey I'm doing some testing while learning js + html5 and other web/mobile frameworks. I have a problem with one of my picture links, which I also need to change the picture dynamically and the target(hopefully). But it won't work. HTML: <div data-role="content" id="firstPageContent"> <p>I'm first in the source order so I'm shown as the page.</p> <p>View internal page called <a href="#second">second</a></p> <a href = "#second" id="mapLink" name="mapLink"><img id="mapLinkImage" alt="a map which links to the mapPage" src="images/main_header.png"/></a> <Button id="loadButton" onClick="load()"/> </div><!-- /content --> js: importScripts(dataManager.js); var mapLink=second; function load(){ alert('called'); document.getElementById('mapLinkImage').src="images/store.map.png"; document.getElementById('mapLink').href = "http://google.com"; } problem: It ain't showing the image as a link, just as a plain image. i think this will work now.

  • Chache problem running two consecutive HTTP GET requests from an APP1 to an APP2

    - by user502052
    I use Ruby on Rails 3 and I have 2 applications (APP1 and APP2) working on two subdomains: app1.domain.local app2.domain.local and I am tryng to run two consecutive HTTP GET requests from APP1 to APP2 like this: Code in APP1 (request): response1 = Net::HTTP.get( URI.parse("http://app2.domain.local?test=first&id=1") ) response2 = Net::HTTP.get( URI.parse("http://app2.domain.local/test=second&id=1") ) Code in APP2 (response): respond_to do |format| if <model_name>.find(params[:id]).<field_name> == "first" <model_name>.find(params[:id]).update_attribute ( <field_name>, <field_value> ) format.xml { render :xml => <model_name>.find(params[:id]).<field_name> } elsif <model_name>.find(params[:id]).<field_name> == "second" format.xml { render :xml => <model_name>.find(params[:id]).<field_name> } end end After the first request I get the correct XML (response1 is what I expect), but on the second it isn't (response2 isn't what I expect). Doing some tests I found that the second time that <model_name>.find(params[:id]).<field_name> run (for the elsif statements) it returns always a blank value so that the code in the elseif statement is never run. Is it possible that the problem is related on caching <model_name>.find(params[:id]).<field_name>? P.S.: I read about eTag and Conditional GET, but I am not sure that I must use that approach. I would like to keep all simple.

  • ProgressDialog won't show, even in onPreExecute of AsyncTask

  • Prevent duplicate entries in arraylist

    - by timyh
    Say I create some object class like so public class thing { private String name; private Integer num; public oDetails (String a, Integer b) { name = a; num = b; } ...gets/ sets/ etc Now I want to create an arraylist to hold a number of this object class like so. ArrayList<thing> myList = new ArrayList<thing>; thing first = new thing("Star Wars", 3); thing second = new thing("Star Wars", 1); myList.add(first); myList.add(second); I would like to include some sort of logic so that in this case...when we try and add object "second" rather than add a new object to the arrayList, we add second.getNum() to first.getNum(). So if you were to iterate through the ArrayList it would be "Star Wars", 4 I am having trouble coming up with an elegant way of handling this. And as the arraylist grows, searching through it to determine if there are duplicate name items becomes cumbersome. Can anyone provide some guidance on this?

  • SQL - table alias scope.

    - by Support - multilanguage SO
    I've just learned ( yesterday ) to use "exists" instead of "in". BAD select * from table where nameid in ( select nameid from othertable where otherdesc = 'SomeDesc' ) GOOD select * from table t where exists ( select nameid from othertable o where t.nameid = o.nameid and otherdesc = 'SomeDesc' ) And I have some questions about this: 1) The explanation as I understood was: "The reason why this is better is because only the matching values will be returned instead of building a massive list of possible results". Does that mean that while the first subquery might return 900 results the second will return only 1 ( yes or no )? 2) In the past I have had the RDBMS complainin: "only the first 1000 rows might be retrieved", this second approach would solve that problem? 3) What is the scope of the alias in the second subquery?... does the alias only lives in the parenthesis? for example select * from table t where exists ( select nameid from othertable o where t.nameid = o.nameid and otherdesc = 'SomeDesc' ) AND select nameid from othertable o where t.nameid = o.nameid and otherdesc = 'SomeOtherDesc' ) That is, if I use the same alias ( o for table othertable ) In the second "exist" will it present any problem with the first exists? or are they totally independent? Is this something Oracle only related or it is valid for most RDBMS? Thanks a lot

  • Wouldn't it be nice to have a type variable referring to the class's instance.

    - by user93197
    I often have a pattern like this: class VectorBase<SubClass, Element> where SubClass : VectorBase<SubClass, Element>, new() where Element : Addable<Element> { Element[] data; public VectorBase(Element[] data) { this.data = data; } public SubClass add(SubClass second) { Element[] newData = new Element[data.Length]; for (int i = 0; i < newData.Length; i++) { newData[i] = data[i].add(second.data[i]); } SubClass result = new SubClass(); result.data = newData; return result; } } class VectorInt : VectorBase<VectorInt, Int32> { } class MyInt : Addable<MyInt> { int data; public MyInt(int data) { this.data = data; } public MyInt add(MyInt t) { return new MyInt(data + t.data); } } interface Addable<T> { T add(T t); } But I would rather just have: class VectorBase2<Element> where Element : Addable<Element> { Element[] data; public VectorBase(Element[] data) { this.data = data; } public SubClass add(SubClass second) { Element[] newData = new Element[data.Length]; for (int i = 0; i < newData.Length; i++) { newData[i] = data[i].add(second.data[i]); } SubClass result = new SubClass(data); return result; } } class VectorInt2 : VectorBase2<Int32> { } Why not make the subclass type available to all classes? Is this technically impossible?

  • XSLT 1 Plain Text Spacing

    - by justkt
    Using Perl's XML::LibXSLT necessitates that I use XSLT 1.0, which means that I am stuck without XSLT 2.0 features. Is there a way that I can still pad text cleanly in a plain-text output from my processing? What I want is: <values> <headers> <header>Header 1</header> <header>Header 2</header> </headers> <value> <one>First value 1</one> <two>First value 2</two> </value> <value> <one>Second value 1</one> <two>Second value 2</two> </value> .... <value> <one>Nth value 1</one> <two>Nth value 2</two> </value> </values> To become Header 1 Header 2 First value 1 First value 2 Second value 1 Second value 2 .... Nth value 1 Nth value 2 I realize that XSLT isn't necessarily ideally suited for this type of formatting, but the data will likely also be formatted in other ways.

  • Switching between 2 UINavigationControllers

    - by Smikey
    Hi all, I seem to have a problem switching between 2 UINavigationControllers, i.e. one which controls the main (selection) menu of my application, and the second which controls the main session (i.e. the user can't go back to the selection menu once they're started a new session). The first works just fine, but I get into trouble when trying to load the second. I have a class called GameViewController which contains the second UINavigationController instance. I set this up as usual, linking it as an IBOutlet to the delegate and setting up the NavController in the GameViewController.xib file with its 'Class' property pointing at GameScreenViewController (my main game screen), and its NIB Name property pointing to the GameScreenViewController nib file. I then create a new instance of GameViewController and load it. In IB, the navigation controller looks fine, with its View 'loaded from "GameScreenViewController"', however when the NavigationController is loaded in the game, it actually loads the GameViewController's UIWindow instance (just a blank window). I'm not sure how to make it load the Navigation Controller's view rather than its own window? Also, another quick question. When I load the second navigation controller from the first, which makes more sense to use: [self.view addSubview:gameViewController.view]; or [self presentModalViewController:gameViewController animated:YES]; Thanks for any help, much appreciated :D Michael

  • wpautop() - when shortcode attributes are on new lines -breaks args array

    I have a custom shortcode tag with a few attributes, and I would like to be able to display its attributes on new lines - to make it more readable to content editors: [component attr1 ="value1" attr2 ="value of the second one" attr3 ="another" attr4 ="value" ... attrN ="valueN"] The reason behind this requirement is that a few attributes might be quite verbose in content. Unfortunately, wpautop() adds some nasty extra markup that breaks the args array like this (using php print_r($args)): Array ( [0] => attr1 [1] => ="value1" /> [3] => attr2 = [4] => "value [5] => of [6] => the [7] => second [8] => one" /> [10] => "" //...and more like this) I've tried with the attributes inline: [component attr1 ="value1" attr2 ="value of the second one" ="value"... attrN ="valueN"] and the output is as expected: Array ( [attr1] => value1 [attr2] => value of the second one [attr3] => //...and so on) is there any way to have the attributes intented and avoid that extra markup that breaks the $args array?

  • Iterative Reduction to Null Matrix

    - by user1459032
    Here's the problem: I'm given a matrix like Input: 1 1 1 1 1 1 1 1 1 At each step, I need to find a "second" matrix of 1's and 0's with no two 1's on the same row or column. Then, I'll subtract the second matrix from the original matrix. I will repeat the process until I get a matrix with all 0's. Furthermore, I need to take the least possible number of steps. I need to print all the "second" matrices in O(n) time. In the above example I can get to the null matrix in 3 steps by subtracting these three matrices in order: Expected output: 1 0 0 0 1 0 0 0 1 0 0 1 1 0 0 0 1 0 0 1 0 0 0 1 1 0 0 I have coded an attempt, in which I am finding the first maximum value and creating the second matrices based on the index of that value. But for the above input I am getting 4 output matrices, which is wrong: My output: 1 0 0 0 1 0 0 0 1 0 1 0 1 0 0 0 0 0 0 0 1 0 0 0 1 0 0 0 0 0 0 0 1 0 1 0 My solution works for most of the test cases but fails for the one given above. Can someone give me some pointers on how to proceed, or find an algorithm that guarantees optimality? Test case that works: Input: 0 2 1 0 0 0 3 0 0 Output 0 1 0 0 0 0 1 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 0 0 1 0 0

  • lock statement not working when there is a loop inside it?

    - by Ngu Soon Hui
    See this code: public class multiply { public Thread myThread; public int Counter { get; private set; } public string name { get; private set; } public void RunConsolePrint() { lock(this) { RunLockCode("lock"); } } private void RunLockCode(string lockCode) { Console.WriteLine("Now thread "+lockCode+" " + name + " has started"); for (int i = 1; i <= Counter; i++) { Console.WriteLine(lockCode+" "+name + ": count has reached " + i + ": total count is " + Counter); } Console.WriteLine("Thread " + lockCode + " " + name + " has finished"); } public multiply(string pname, int pCounter) { name = pname; Counter = pCounter; myThread = new Thread(new ThreadStart(RunConsolePrint)); } } And this is the test run code: static void Main(string[] args) { int counter = 50; multiply m2 = new multiply("Second", counter); multiply m1 = new multiply("First", counter); m1.myThread.Start(); m2.myThread.Start(); Console.ReadLine(); } I would expect that m2 must execute from start to finish before m1 starts executing, or vice versa, because of the lock statement. But the result I found was the call to lock first and lock second was intermingled together, i.e., something like this Now thread lock First has started Now thread lock Second has started lock First: Count has reached 1: total count is 50 lock First: Count has reached 2: total count is 50 lock Second: Count has reached 1: total count is 50 What did I do wrong?

  • Prevent event from parent element to child element in jquery

    - by sonam
    I have binded event as below: $(document).delegate('.budget', 'click', function(e){ if ($(this).hasClass('collapsed')) { $(this).removeClass('collapsed'); $(this).addClass('expanded'); } else if ($(this).hasClass('expanded')) { $(this).removeClass('expanded'); $(this).addClass('collapsed'); } }); Basically this toggles between expand and collapse. I have another event binded as below: $('[id^="tree"]').delegate('.collapsed', 'click', function(e){ var elementId = $(this).attr('id'); hideChildElement(elementId); }); The elements binded by the second event binding are parents of elements binded by first event binding. What happens is that on clicking on the element from the first binding event method also triggers the event binded by second event binding. I want to prevent any events from binding from second event binding to 1st event binding method. If element A is binded to click event from first event binding and B is binded to second event binding (A is inside B or A is child of B), I dont want any event of B to propagate to A. Note I tried e.stopImmediatePropagation(); but did not worked
