  • Refresh page isnt working in asp.net using treeview

    - by Greg
    Hi, I am trying to refresh an asp.net page using this command: <meta http-equiv="Refresh" content="10"/> On that page I have 2 treeviews. The refresh works ok when I just open the page, but when I click on one of the treeviews and expand it, the refresh stopps working and the page isnt being refreshed. Any ideas why this can happen? Is there any connection to the treeview being expanded? Here is the full code of the page: public partial class Results : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } // Function that moves reviewed yellow card to reviewed tree protected void ycActiveTree_SelectedNodeChanged(object sender, EventArgs e) { ycActiveTree.SelectedNode.Text = "Move To Active"; ycReviewedTree.PopulateNodesFromClient = false; ycReviewedTree.Nodes[ycReviewedTree.Nodes.Count - 1].ChildNodes.Add(ycActiveTree.SelectedNode.Parent); Application["reviewedTree"] = new ArrayList(); int count = ((ArrayList)Application["activeTree"]).Count; // Move all the nodes from activeTree application to reviewedTree application for (int i = 0; Application["activeTree"] != null && i < count; i++) { ((ArrayList)Application["reviewedTree"]).Add(((ArrayList)Application["activeTree"])[i]); ((ArrayList)Application["activeTree"]).RemoveAt(0); } } protected void ycActiveTree_TreeNodePopulate(object sender, TreeNodeEventArgs e) { if (Application["idList"] != null && e.Node.Depth == 0) { string[] words = ((String)Application["idList"]).Split(' '); // Yellow Card details TreeNode child = new TreeNode(""); // Go over all the yellow card details and populate the treeview for (int i = 1; i < words.Length; i++) { child.SelectAction = TreeNodeSelectAction.None; // Same yellow card if (words[i] != "*") { // End of details and start of point ip's if (words[i] == "$") { // Add the yellow card node TreeNode yellowCardNode = new TreeNode(child.Text); yellowCardNode.SelectAction = TreeNodeSelectAction.Expand; e.Node.ChildNodes.Add(yellowCardNode); child.Text = ""; } // yellow card details else { child.Text = child.Text + words[i] + " "; } } // End of yellow card else { child.PopulateOnDemand = false; child.SelectAction = TreeNodeSelectAction.None; // Populate the yellow card node e.Node.ChildNodes[e.Node.ChildNodes.Count - 1].ChildNodes.Add(child); TreeNode moveChild = new TreeNode("Move To Reviewed"); moveChild.PopulateOnDemand = false; moveChild.SelectAction = TreeNodeSelectAction.Select; e.Node.ChildNodes[e.Node.ChildNodes.Count - 1].ChildNodes.Add(moveChild); child = new TreeNode(""); Application["activeTree"] = new ArrayList(); ((ArrayList)Application["activeTree"]).Add(e.Node.ChildNodes[e.Node.ChildNodes.Count - 1]); } } } // If there arent new yellow cards else if (Application["activeTree"] != null) { // Populate the active tree for (int i = 0; i < ((ArrayList)Application["activeTree"]).Count; i++) { e.Node.ChildNodes.Add((TreeNode)((ArrayList)Application["activeTree"])[i]); } } // If there were new yellow cards and nodes that moved from reviewed tree to active tree if (Application["idList"] != null && Application["activeTree"] != null && e.Node.ChildNodes.Count != ((ArrayList)Application["activeTree"]).Count) { for (int i = e.Node.ChildNodes.Count; i < ((ArrayList)Application["activeTree"]).Count; i++) { e.Node.ChildNodes.Add((TreeNode)((ArrayList)Application["activeTree"])[i]); } } // Nullify the yellow card id's Application["idList"] = null; } protected void ycReviewedTree_SelectedNodeChanged(object sender, EventArgs e) { ycActiveTree.PopulateNodesFromClient = false; ycReviewedTree.SelectedNode.Text = "Move To Reviewed"; ycActiveTree.Nodes[ycActiveTree.Nodes.Count - 1].ChildNodes.Add(ycReviewedTree.SelectedNode.Parent); int count = ((ArrayList)Application["reviewedTree"]).Count; // Move all the nodes from reviewedTree application to activeTree application for (int i = 0; Application["reviewedTree"] != null && i < count; i++) { ((ArrayList)Application["activeTree"]).Add(((ArrayList)Application["reviewedTree"])[i]); ((ArrayList)Application["reviewedTree"]).RemoveAt(0); } } protected void ycReviewedTree_TreeNodePopulate(object sender, TreeNodeEventArgs e) { if (Application["reviewedTree"] != null) { // Populate the reviewed tree for (int i = 0; i < ((ArrayList)Application["reviewedTree"]).Count; i++) { e.Node.ChildNodes.Add((TreeNode)((ArrayList)Application["reviewedTree"])[i]); } } } } Thanks, Greg

  • How do I make a simple image-based button with visual states in Silverlight 3?

    - by Jacob
    At my previous company, we created our RIAs using Flex with graphical assets created in Flash. In Flash, you could simply lay out your graphics for different states, i.e. rollover, disabled. Now, I'm working on a Silverlight 3 project. I've been given a bunch of images that need to serve as the graphics for buttons that have a rollover, pressed, and normal state. I cannot figure out how to simply create buttons with different images for different visual states in Visual Studio 2008 or Expression Blend 3. Here's where I am currently. My button is defined like this in the XAML: <Button Style="{StaticResource MyButton}"/> The MyButton style appears as follows: <Style x:Key="MyButton" TargetType="Button"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Image Source="/Assets/Graphics/mybtn_up.png" Width="54" Height="24"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="FocusStates"> <VisualState x:Name="Focused"/> <VisualState x:Name="Unfocused"/> </VisualStateGroup> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal"/> <VisualState x:Name="MouseOver"/> <VisualState x:Name="Pressed"/> <VisualState x:Name="Disabled"/> </VisualStateGroup> </VisualStateManager.VisualStateGroups> </Image> </ControlTemplate> </Setter.Value> </Setter> </Style> I cannot figure out how to assign a different template to different states, nor how to change the image's source based on which state I'm in. How do I do this? Also, if you know of any good documentation that describes how styles work in Silverlight, that would be great. All of the search results I can come up with are frustratingly unhelpful. Edit: I found a way to change the image via storyboards like this: <Style x:Key="MyButton" TargetType="Button"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Image Source="/Assets/Graphics/mybtn_up.png" Width="54" Height="24" x:Name="Image"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="FocusStates"> <VisualState x:Name="Focused"/> <VisualState x:Name="Unfocused"/> </VisualStateGroup> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal"/> <VisualState x:Name="MouseOver"> <Storyboard Storyboard.TargetName="Image" Storyboard.TargetProperty="Source"> <ObjectAnimationUsingKeyFrames> <DiscreteObjectKeyFrame KeyTime="0" Value="/Assets/Graphics/mybtn_over.png"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Pressed"> <Storyboard Storyboard.TargetName="Image" Storyboard.TargetProperty="Source"> <ObjectAnimationUsingKeyFrames> <DiscreteObjectKeyFrame KeyTime="0" Value="/Assets/Graphics/mybtn_active.png"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Disabled"/> </VisualStateGroup> </VisualStateManager.VisualStateGroups> </Image> </ControlTemplate> </Setter.Value> </Setter> </Style> However, this seems like a strange way of doing things to me. Is there a more standard way of accomplishing this?

  • Exception - Illegal Block size during decryption(Android)

    - by Vamsi
    I am writing an application which encrypts and decrypts the user notes based on the user set password. i used the following algorithms for encryption/decryption 1. PBEWithSHA256And256BitAES-CBC-BC 2. PBEWithMD5And128BitAES-CBC-OpenSSL e_Cipher = Cipher.getInstance(PBEWithSHA256And256BitAES-CBC-BC); d_Cipher = Cipher.getInstance(PBEWithSHA256And256BitAES-CBC-BC); e_Cipher.init() d_Cipher.init() encryption is working well, but when trying to decrypt it gives Exception - Illegal Block size after encryption i am converting the cipherText to HEX and storing it in a sqlite database. i am retrieving correct values from the sqlite database during decyption but when calling d_Cipher.dofinal() it throws the Exception. I thought i missed to specify the padding and tried to check what are the other available cipher algorithms but i was unable to found. so request you to please give the some knowledge on what are the cipher algorithms and padding that are supported by Android? if the algorithm which i used can be used for padding, how should i specify the padding mechanism? I am pretty new to Encryption so tried a couple of algorithms which are available in BouncyCastle.java but unsuccessful.

  • 12c - Utl_Call_Stack...

    - by noreply(at)blogger.com (Thomas Kyte)
    Over the next couple of months, I'll be writing about some cool new little features of Oracle Database 12c - things that might not make the front page of Oracle.com.  I'm going to start with a new package - UTL_CALL_STACK.In the past, developers have had access to three functions to try to figure out "where the heck am I in my code", they were:dbms_utility.format_call_stackdbms_utility.format_error_backtracedbms_utility.format_error_stackNow these routines, while useful, were of somewhat limited use.  Let's look at the format_call_stack routine for a reason why.  Here is a procedure that will just print out the current call stack for us:ops$tkyte%ORA12CR1> create or replace  2  procedure Print_Call_Stack  3  is  4  begin  5    DBMS_Output.Put_Line(DBMS_Utility.Format_Call_Stack());  6  end;  7  /Procedure created.Now, if we have a package - with nested functions and even duplicated function names:ops$tkyte%ORA12CR1> create or replace  2  package body Pkg is  3    procedure p  4    is  5      procedure q  6      is  7        procedure r  8        is  9          procedure p is 10          begin 11            Print_Call_Stack(); 12            raise program_error; 13          end p; 14        begin 15          p(); 16        end r; 17      begin 18        r(); 19      end q; 20    begin 21      q(); 22    end p; 23  end Pkg; 24  /Package body created.When we execute the procedure PKG.P - we'll see as a result:ops$tkyte%ORA12CR1> exec pkg.p----- PL/SQL Call Stack -----  object      line  object  handle    number  name0x6e891528         4  procedure OPS$TKYTE.PRINT_CALL_STACK0x6ec4a7c0        10  package body OPS$TKYTE.PKG0x6ec4a7c0        14  package body OPS$TKYTE.PKG0x6ec4a7c0        17  package body OPS$TKYTE.PKG0x6ec4a7c0        20  package body OPS$TKYTE.PKG0x76439070         1  anonymous blockBEGIN pkg.p; END;*ERROR at line 1:ORA-06501: PL/SQL: program errorORA-06512: at "OPS$TKYTE.PKG", line 11ORA-06512: at "OPS$TKYTE.PKG", line 14ORA-06512: at "OPS$TKYTE.PKG", line 17ORA-06512: at "OPS$TKYTE.PKG", line 20ORA-06512: at line 1The bit in red above is the output from format_call_stack whereas the bit in black is the error message returned to the client application (it would also be available to you via the format_error_backtrace API call). As you can see - it contains useful information but to use it you would need to parse it - and that can be trickier than it seems.  The format of those strings is not set in stone, they have changed over the years (I wrote the "who_am_i", "who_called_me" functions, I did that by parsing these strings - trust me, they change over time!).Starting in 12c - we'll have structured access to the call stack and a series of API calls to interrogate this structure.  I'm going to rewrite the print_call_stack function as follows:ops$tkyte%ORA12CR1> create or replace 2  procedure Print_Call_Stack  3  as  4    Depth pls_integer := UTL_Call_Stack.Dynamic_Depth();  5    6    procedure headers  7    is  8    begin  9        dbms_output.put_line( 'Lexical   Depth   Line    Name' ); 10        dbms_output.put_line( 'Depth             Number      ' ); 11        dbms_output.put_line( '-------   -----   ----    ----' ); 12    end headers; 13    procedure print 14    is 15    begin 16        headers; 17        for j in reverse 1..Depth loop 18          DBMS_Output.Put_Line( 19            rpad( utl_call_stack.lexical_depth(j), 10 ) || 20                    rpad( j, 7) || 21            rpad( To_Char(UTL_Call_Stack.Unit_Line(j), '99'), 9 ) || 22            UTL_Call_Stack.Concatenate_Subprogram 23                       (UTL_Call_Stack.Subprogram(j))); 24        end loop; 25    end; 26  begin 27    print; 28  end; 29  /Here we are able to figure out what 'depth' we are in the code (utl_call_stack.dynamic_depth) and then walk up the stack using a loop.  We will print out the lexical_depth, along with the line number within the unit we were executing plus - the unit name.  And not just any unit name, but the fully qualified, all of the way down to the subprogram name within a package.  Not only that - but down to the subprogram name within a subprogram name within a subprogram name.  For example - running the PKG.P procedure again results in:ops$tkyte%ORA12CR1> exec pkg.pLexical   Depth   Line    NameDepth             Number-------   -----   ----    ----1         6       20      PKG.P2         5       17      PKG.P.Q3         4       14      PKG.P.Q.R4         3       10      PKG.P.Q.R.P0         2       26      PRINT_CALL_STACK1         1       17      PRINT_CALL_STACK.PRINTBEGIN pkg.p; END;*ERROR at line 1:ORA-06501: PL/SQL: program errorORA-06512: at "OPS$TKYTE.PKG", line 11ORA-06512: at "OPS$TKYTE.PKG", line 14ORA-06512: at "OPS$TKYTE.PKG", line 17ORA-06512: at "OPS$TKYTE.PKG", line 20ORA-06512: at line 1This time - we get much more than just a line number and a package name as we did previously with format_call_stack.  We not only got the line number and package (unit) name - we got the names of the subprograms - we can see that P called Q called R called P as nested subprograms.  Also note that we can see a 'truer' calling level with the lexical depth, we can see we "stepped" out of the package to call print_call_stack and that in turn called another nested subprogram.This new package will be a nice addition to everyone's error logging packages.  Of course there are other functions in there to get owner names, the edition in effect when the code was executed and more. See UTL_CALL_STACK for all of the details.

  • 3D Graphics with XNA Game Studio 4.0 bug in light map?

    - by Eibis
    i'm following the tutorials on 3D Graphics with XNA Game Studio 4.0 and I came up with an horrible effect when I tried to implement the Light Map http://i.stack.imgur.com/BUWvU.jpg this effect shows up when I look towards the center of the house (and it moves with me). it has this shape because I'm using a sphere to represent light; using other light shapes gives different results. I'm using a class PreLightingRenderer: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Graphics; using Dhpoware;

  • Help required in adding new methods, properties into existing classes dynamically

    - by Bepenfriends
    Hi All, I am not sure whether it is possible to achieve this kind of implementation in Dot Net. Below are the information Currently we are on an application which is done in COM+, ASP, XSL, XML technologies. It is a multi tier architecture application in which COM+ acts as the BAL. The execution steps for any CRUD operation will be defined using a seperate UI which uses XML to store the information. BAL reads the XML and understands the execution steps which are defined and executes corresponding methods in DLL. Much like EDM we have our custom model (using XML) which determines which property of object is searchable, retrievable etc. Based on this information BAL constructs queries and calls procedures to get the data. In the current application both BAL and DAL are heavily customizable without doing any code change. the results will be transmitted to presentation layer in XML format which constructs the UI based on the data recieved. Now I am creating a migration project which deals with employee information. It is also going to follow the N Tier architecture in which the presentation layer communicates with BAL which connects to DAL to return the Data. Here is the problem, In our existing version we are handling every information as XML in its native form (no converstion of object etc), but in the migration project, Team is really interested in utilizing the OOP model of development where every information which is sent from BAL need to be converted to objects of its respective types (example employeeCollection, Address Collection etc). If we have the static number of data returned from BAL we can have a class which contains those nodes as properties and we can access the same. But in our case the data returned from our BAL need to be customized. How can we handle the customization in presentation layer which is converting the result to an Object. Below is an example of the XML returned <employees> <employee> <firstName>Employee 1 First Name</firstName> <lastName>Employee 1 Last Name</lastName> <addresses> <address> <addressType>1</addressType> <StreetName>Street name1</StreetName> <RegionName>Region name</RegionName> <address> <address> <addressType>2</addressType> <StreetName>Street name2</StreetName> <RegionName>Region name</RegionName> <address> <address> <addressType>3</addressType> <StreetName>Street name3</StreetName> <RegionName>Region name</RegionName> <address> <addresses> </employee> <employee> <firstName>Employee 2 First Name</firstName> <lastName>Employee 2 Last Name</lastName> <addresses> <address> <addressType>1</addressType> <StreetName>Street name1</StreetName> <RegionName>Region name</RegionName> <address> <address> <addressType>2</addressType> <StreetName>Street name2</StreetName> <RegionName>Region name</RegionName> <address> <addresses> </employee> </employees> If these are the only columns then i can write a class which is like public class Address{ public int AddressType {get;set;}; public string StreetName {get;set;}; public string RegionName {get;set;}; } public class Employee{ public string FirstName {get; set;} public string LastName {get; set;} public string AddressCollection {get; set;} } public class EmployeeCollection : List<Employee>{ public bool Add (Employee Data){ .... } } public class AddressCollection : List<Address>{ public bool Add (Address Data){ .... } } This class will be provided to customers and consultants as DLLs. We will not provide the source code for the same. Now when the consultants or customers does customization(example adding country to address and adding passport information object with employee object) they must be able to access those properties in these classes, but without source code they will not be able to do those modifications.which makes the application useless. Is there is any way to acomplish this in DotNet. I thought of using Anonymous classes but, the problem with Anonymous classes are we can not have methods in it. I am not sure how can i fit the collection objects (which will be inturn an anonymous class) Not sure about datagrid / user control binding etc. I also thought of using CODEDom to create classes runtime but not sure about the meory, performance issues. also the classes must be created only once and must use the same till there is another change. Kindly help me out in this problem. Any kind of help meterial/ cryptic code/ links will be helpful.

  • Using CSS3 media queries in HTML 5 pages

    - by nikolaosk
    This is going to be the seventh post in a series of posts regarding HTML 5. You can find the other posts here , here , here, here , here and here. In this post I will provide a hands-on example on how to use CSS 3 Media Queries in HTML 5 pages. This is a very important feature since nowadays lots of users view websites through their mobile devices. Web designers were able to define media-specific style sheets for quite a while, but have been limited to the type of output. The output could only be Screen, Print .The way we used to do things before CSS 3 was to have separate CSS files and the browser decided which style sheet to use. Please have a look at the snippet below - HTML 4 media queries <link rel="stylesheet" type="text/css" media="screen" href="styles.css"> <link rel="stylesheet" type="text/css" media="print" href="print-styles.css"> ?he browser determines which style to use. With CSS 3 we can have all media queries in one stylesheet. Media queries can determine the resolution of the device, the orientation of the device, the width and height of the device and the width and height of the browser window.We can also include CSS 3 media queries in separate stylesheets. In order to be absolutely clear this is not (and could not be) a detailed tutorial on HTML 5. There are other great resources for that.Navigate to the excellent interactive tutorials of W3School. Another excellent resource is HTML 5 Doctor. Two very nice sites that show you what features and specifications are implemented by various browsers and their versions are http://caniuse.com/ and http://html5test.com/. At this times Chrome seems to support most of HTML 5 specifications.Another excellent way to find out if the browser supports HTML 5 and CSS 3 features is to use the Javascript lightweight library Modernizr. In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here. Before I go on with the actual demo I will use the (http://www.caniuse.com) to see the support for CSS 3 Media Queries from the latest versions of modern browsers. Please have a look at the picture below. We see that all the latest versions of modern browsers support this feature. We can see that even IE 9 supports this feature.   Let's move on with the actual demo.  This is going to be a rather simple demo.I create a simple HTML 5 page. The markup follows and it is very easy to use and understand.This is a page with a 2 column layout. <!DOCTYPE html><html lang="en">  <head>    <title>HTML 5, CSS3 and JQuery</title>    <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">       </head>  <body>    <div id="header">      <h1>Learn cutting edge technologies</h1>      <p>HTML 5, JQuery, CSS3</p>    </div>    <div id="main">      <div id="mainnews">        <div>          <h2>HTML 5</h2>        </div>        <div>          <p>            HTML5 is the latest version of HTML and XHTML. The HTML standard defines a single language that can be written in HTML and XML. It attempts to solve issues found in previous iterations of HTML and addresses the needs of Web Applications, an area previously not adequately covered by HTML.          </p>          <div class="quote">            <h4>Do More with Less</h4>            <p>             jQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development.             </p>            </div>          <p>            The HTML5 test(html5test.com) score is an indication of how well your browser supports the upcoming HTML5 standard and related specifications. Even though the specification isn't finalized yet, all major browser manufacturers are making sure their browser is ready for the future. Find out which parts of HTML5 are already supported by your browser today and compare the results with other browsers.                      The HTML5 test does not try to test all of the new features offered by HTML5, nor does it try to test the functionality of each feature it does detect. Despite these shortcomings we hope that by quantifying the level of support users and web developers will get an idea of how hard the browser manufacturers work on improving their browsers and the web as a development platform.</p>        </div>      </div>              <div id="CSS">        <div>          <h2>CSS 3 Intro</h2>        </div>        <div>          <p>          Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation semantics (the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML, but the language can also be applied to any kind of XML document, including plain XML, SVG and XUL.          </p>        </div>      </div>            <div id="CSSmore">        <div>          <h2>CSS 3 Purpose</h2>        </div>        <div>          <p>            CSS is designed primarily to enable the separation of document content (written in HTML or a similar markup language) from document presentation, including elements such as the layout, colors, and fonts.[1] This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple pages to share formatting, and reduce complexity and repetition in the structural content (such as by allowing for tableless web design).          </p>        </div>      </div>                </div>    <div id="footer">        <p>Feel free to google more about the subject</p>      </div>     </body>  </html>    The CSS code (style.css) follows  body{        line-height: 30px;        width: 1024px;        background-color:#eee;      }            p{        font-size:17px;    font-family:"Comic Sans MS"      }      p,h2,h3,h4{        margin: 0 0 20px 0;      }            #main, #header, #footer{        width: 100%;        margin: 0px auto;        display:block;      }            #header{        text-align: center;         border-bottom: 1px solid #000;         margin-bottom: 30px;      }            #footer{        text-align: center;         border-top: 1px solid #000;         margin-bottom: 30px;      }            .quote{        width: 200px;       margin-left: 10px;       padding: 5px;       float: right;       border: 2px solid #000;       background-color:#F9ACAE;      }            .quote :last-child{        margin-bottom: 0;      }            #main{        column-count:2;        column-gap:20px;        column-rule: 1px solid #000;        -moz-column-count: 2;        -webkit-column-count: 2;        -moz-column-gap: 20px;        -webkit-column-gap: 20px;        -moz-column-rule: 1px solid #000;        -webkit-column-rule: 1px solid #000;      } Now I view the page in the browser.Now I am going to write a media query and add some more rules in the .css file in order to change the layout of the page when the page is viewed by mobile devices. @media only screen and (max-width: 480px) {          body{            width: 480px;          }          #main{            -moz-column-count: 1;            -webkit-column-count: 1;          }        }   I am specifying that this media query applies only to screen and a max width of 480 px. If this condition is true, then I add new rules for the body element. I change the number of columns to one. This rule will not be applied unless the maximum width is 480px or less.  As I decrease the size-width of the browser window I see no change in the column's layout. Have a look at the picture below. When I resize the window and the width of the browser so the width is less than 480px, the media query and its respective rules take effect.We can scroll vertically to view the content which is a more optimised viewing experience for mobile devices. Have a look at the picture below Hope it helps!!!!

  • PERL XPath Parser Help

    - by cognvision
    I want to pull in data using a XML::XPath parser from a XML DB file from the Worldbank site. The problem is that I'm not seeing any results in the output. I must be missing something in the code. Ideally, I would like to extract just the death rate statistics from each country XML DB (year and value). I'm using this as part of my input: http://data.worldbank.org/sites/default/files/countries/en/afghanistan_en.xml use strict; use LWP 5.64; use HTML::ContentExtractor; use XML::XPath; my $agent1 = LWP::UserAgent->new; my $extractor = HTML::ContentExtractor->new(); #Retrieve main Worldbank country site my $mainlink = "http://data.worldbank.org/country/"; my $page = $agent1->get("$mainlink"); my $fulltext = $page->decoded_content(); #Match to just all available countries in Worldbank my $country = ""; my @countryList; if (@countryList = $fulltext =~ m/(http:\/\/data\.worldbank\.org\/country\/.*?")/gi){ foreach $country(@countryList){ #Remove " at the end of link $country=~s/\"//gi; print "\n" . $country; #Retrieve each country profile's XML DB file my $page = $agent1->get("$country"); my $fulltext = $page->decoded_content(); my $XML_DB = ""; my @countryXMLDBList; if (@countryXMLDBList = $fulltext =~ m/(http:\/\/data\.worldbank\.org\/sites\/default\/files\/countries\/en\/.*?\.xml)/gi){ foreach $XML_DB(@countryXMLDBList){ my $page = $agent1->get("$XML_DB"); my $fulltext = $page->decoded_content(); #print $fulltext; #Use XML XPath parser to find elements related to death rate my $xp = XML::XPath->new($fulltext); #my $xp = XML::XPath->new("afghanistan_en.xml"); my $nodeSet = $xp->find("//*"); if (!$nodeSet->isa('XML::XPath::NodeSet') || $nodeSet->size() == 0) { #No match found print "\nMatch not found!"; exit; } else { foreach my $node ($nodeSet->get_nodelist){ print "\n" . $node->find('country')->string_value; print "\n" . $node->find('indicator')->string_value; print "\n" . $node->find('year')->string_value; print "\n" . $node->find('value')->string_value; exit; } } } #Build line graph based on death rate statistics and output some image file format } } } I am also looking into using the xpath expression "following-sibling", but not sure how to use it correctly. For example, I have the following set of XML data where I am only interested in pulling siblings directly after the indicator for just death rate data. <data> <country id="AFG">Afghanistan</country> <indicator id="SP.DYN.CDRT.IN">Death rate, crude (per 1,000 people)</indicator> <year>2006</year> <value>20.3410000</value> </data> - <data> <country id="AFG">Afghanistan</country> <indicator id="SP.DYN.CDRT.IN">Death rate, crude (per 1,000 people)</indicator> <year>2007</year> <value>19.9480000</value> </data> - <data> <country id="AFG">Afghanistan</country> <indicator id="SP.DYN.CDRT.IN">Death rate, crude (per 1,000 people)</indicator> <year>2008</year> <value>19.5720000</value> </data> - <data> <country id="AFG">Afghanistan</country> <indicator id="IC.EXP.DOCS">Documents to export (number)</indicator> <year>2005</year> <value>7.0000000</value> </data> - <data> <country id="AFG">Afghanistan</country> <indicator id="IC.EXP.DOCS">Documents to export (number)</indicator> <year>2006</year> <value>12.0000000</value> </data> - <data> <country id="AFG">Afghanistan</country> <indicator id="IC.EXP.DOCS">Documents to export (number)</indicator> <year>2007</year> <value>12.0000000</value> </data> Any help would be much appreciated!!!

  • Help needed on an SQL configuration problem.

    - by user321048
    I have been banging my head with this one more the two weeks, and still don't know what the problem is ( I can't narrow it down). The problem is the following. I have a solution with 3 project in it all written in c# and I with LINQ. One project is the main web site, the other is the data layer (communication with the database) and the third one is a custom little CMS. The problem is the following: On a hosting provider when I publish the site it all works perfectly, but this site was needed to be hosted on the client server so I needed to do that. But the problem is that I also needed to configure the client server, because they don't have an Administrator employed (I know, I know ;) ). For the first time I some how managed, to set it up but a problem appear. My main web site is working just as it suppose to be - it reads (communicates with) the database, but My CMS is not. It shows the first log in page, but after that when I try to log in it throws the following error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)

So far I have tried the following: -setting time out on connection string to a higher value -configuration and after that turning off server firewall -checking the connection string over and over again (they are the same for all three projects and are saved in web.config) Important notes: I have tried executing the project from VS2008 with a connection string to the same database and the results are the same. That's why I think the problem is the SQL Server 2005 and not the IIS7. Any bit of information is more then welcomed.

  • Loosely coupled .NET Cache Provider using Dependency Injection

    - by Rhames
    I have recently been reading the excellent book “Dependency Injection in .NET”, written by Mark Seemann. I do not generally buy software development related books, as I never seem to have the time to read them, but I have found the time to read Mark’s book, and it was time well spent I think. Reading the ideas around Dependency Injection made me realise that the Cache Provider code I wrote about earlier (see http://geekswithblogs.net/Rhames/archive/2011/01/10/using-the-asp.net-cache-to-cache-data-in-a-model.aspx) could be refactored to use Dependency Injection, which should produce cleaner code. The goals are to: Separate the cache provider implementation (using the ASP.NET data cache) from the consumers (loose coupling). This will also mean that the dependency on System.Web for the cache provider does not ripple down into the layers where it is being consumed (such as the domain layer). Provide a decorator pattern to allow a consumer of the cache provider to be implemented separately from the base consumer (i.e. if we have a base repository, we can decorate this with a caching version). Although I used the term repository, in reality the cache consumer could be just about anything. Use constructor injection to provide the Dependency Injection, with a suitable DI container (I use Castle Windsor). The sample code for this post is available on github, https://github.com/RobinHames/CacheProvider.git ICacheProvider In the sample code, the key interface is ICacheProvider, which is in the domain layer. 1: using System; 2: using System.Collections.Generic; 3:   4: namespace CacheDiSample.Domain 5: { 6: public interface ICacheProvider<T> 7: { 8: T Fetch(string key, Func<T> retrieveData, DateTime? absoluteExpiry, TimeSpan? relativeExpiry); 9: IEnumerable<T> Fetch(string key, Func<IEnumerable<T>> retrieveData, DateTime? absoluteExpiry, TimeSpan? relativeExpiry); 10: } 11: }   This interface contains two methods to retrieve data from the cache, either as a single instance or as an IEnumerable. the second paramerter is of type Func<T>. This is the method used to retrieve data if nothing is found in the cache. The ASP.NET implementation of the ICacheProvider interface needs to live in a project that has a reference to system.web, typically this will be the root UI project, or it could be a separate project. The key thing is that the domain or data access layers do not need system.web references adding to them. In my sample MVC application, the CacheProvider is implemented in the UI project, in a folder called “CacheProviders”: 1: using System; 2: using System.Collections.Generic; 3: using System.Linq; 4: using System.Web; 5: using System.Web.Caching; 6: using CacheDiSample.Domain; 7:   8: namespace CacheDiSample.CacheProvider 9: { 10: public class CacheProvider<T> : ICacheProvider<T> 11: { 12: public T Fetch(string key, Func<T> retrieveData, DateTime? absoluteExpiry, TimeSpan? relativeExpiry) 13: { 14: return FetchAndCache<T>(key, retrieveData, absoluteExpiry, relativeExpiry); 15: } 16:   17: public IEnumerable<T> Fetch(string key, Func<IEnumerable<T>> retrieveData, DateTime? absoluteExpiry, TimeSpan? relativeExpiry) 18: { 19: return FetchAndCache<IEnumerable<T>>(key, retrieveData, absoluteExpiry, relativeExpiry); 20: } 21:   22: #region Helper Methods 23:   24: private U FetchAndCache<U>(string key, Func<U> retrieveData, DateTime? absoluteExpiry, TimeSpan? relativeExpiry) 25: { 26: U value; 27: if (!TryGetValue<U>(key, out value)) 28: { 29: value = retrieveData(); 30: if (!absoluteExpiry.HasValue) 31: absoluteExpiry = Cache.NoAbsoluteExpiration; 32:   33: if (!relativeExpiry.HasValue) 34: relativeExpiry = Cache.NoSlidingExpiration; 35:   36: HttpContext.Current.Cache.Insert(key, value, null, absoluteExpiry.Value, relativeExpiry.Value); 37: } 38: return value; 39: } 40:   41: private bool TryGetValue<U>(string key, out U value) 42: { 43: object cachedValue = HttpContext.Current.Cache.Get(key); 44: if (cachedValue == null) 45: { 46: value = default(U); 47: return false; 48: } 49: else 50: { 51: try 52: { 53: value = (U)cachedValue; 54: return true; 55: } 56: catch 57: { 58: value = default(U); 59: return false; 60: } 61: } 62: } 63:   64: #endregion 65:   66: } 67: }   The FetchAndCache helper method checks if the specified cache key exists, if it does not, the Func<U> retrieveData method is called, and the results are added to the cache. Using Castle Windsor to register the cache provider In the MVC UI project (my application root), Castle Windsor is used to register the CacheProvider implementation, using a Windsor Installer: 1: using Castle.MicroKernel.Registration; 2: using Castle.MicroKernel.SubSystems.Configuration; 3: using Castle.Windsor; 4:   5: using CacheDiSample.Domain; 6: using CacheDiSample.CacheProvider; 7:   8: namespace CacheDiSample.WindsorInstallers 9: { 10: public class CacheInstaller : IWindsorInstaller 11: { 12: public void Install(IWindsorContainer container, IConfigurationStore store) 13: { 14: container.Register( 15: Component.For(typeof(ICacheProvider<>)) 16: .ImplementedBy(typeof(CacheProvider<>)) 17: .LifestyleTransient()); 18: } 19: } 20: }   Note that the cache provider is registered as a open generic type. Consuming a Repository I have an existing couple of repository interfaces defined in my domain layer: IRepository.cs 1: using System; 2: using System.Collections.Generic; 3:   4: using CacheDiSample.Domain.Model; 5:   6: namespace CacheDiSample.Domain.Repositories 7: { 8: public interface IRepository<T> 9: where T : EntityBase 10: { 11: T GetById(int id); 12: IList<T> GetAll(); 13: } 14: }   IBlogRepository.cs 1: using System; 2: using CacheDiSample.Domain.Model; 3:   4: namespace CacheDiSample.Domain.Repositories 5: { 6: public interface IBlogRepository : IRepository<Blog> 7: { 8: Blog GetByName(string name); 9: } 10: }   These two repositories are implemented in the DataAccess layer, using Entity Framework to retrieve data (this is not important though). One important point is that in the BaseRepository implementation of IRepository, the methods are virtual. This will allow the decorator to override them. The BlogRepository is registered in a RepositoriesInstaller, again in the MVC UI project. 1: using Castle.MicroKernel.Registration; 2: using Castle.MicroKernel.SubSystems.Configuration; 3: using Castle.Windsor; 4:   5: using CacheDiSample.Domain.CacheDecorators; 6: using CacheDiSample.Domain.Repositories; 7: using CacheDiSample.DataAccess; 8:   9: namespace CacheDiSample.WindsorInstallers 10: { 11: public class RepositoriesInstaller : IWindsorInstaller 12: { 13: public void Install(IWindsorContainer container, IConfigurationStore store) 14: { 15: container.Register(Component.For<IBlogRepository>() 16: .ImplementedBy<BlogRepository>() 17: .LifestyleTransient() 18: .DependsOn(new 19: { 20: nameOrConnectionString = "BloggingContext" 21: })); 22: } 23: } 24: }   Now I can inject a dependency on the IBlogRepository into a consumer, such as a controller in my sample code: 1: using System; 2: using System.Collections.Generic; 3: using System.Linq; 4: using System.Web; 5: using System.Web.Mvc; 6:   7: using CacheDiSample.Domain.Repositories; 8: using CacheDiSample.Domain.Model; 9:   10: namespace CacheDiSample.Controllers 11: { 12: public class HomeController : Controller 13: { 14: private readonly IBlogRepository blogRepository; 15:   16: public HomeController(IBlogRepository blogRepository) 17: { 18: if (blogRepository == null) 19: throw new ArgumentNullException("blogRepository"); 20:   21: this.blogRepository = blogRepository; 22: } 23:   24: public ActionResult Index() 25: { 26: ViewBag.Message = "Welcome to ASP.NET MVC!"; 27:   28: var blogs = blogRepository.GetAll(); 29:   30: return View(new Models.HomeModel { Blogs = blogs }); 31: } 32:   33: public ActionResult About() 34: { 35: return View(); 36: } 37: } 38: }   Consuming the Cache Provider via a Decorator I used a Decorator pattern to consume the cache provider, this means my repositories follow the open/closed principle, as they do not require any modifications to implement the caching. It also means that my controllers do not have any knowledge of the caching taking place, as the DI container will simply inject the decorator instead of the root implementation of the repository. The first step is to implement a BlogRepository decorator, with the caching logic in it. Note that this can reside in the domain layer, as it does not require any knowledge of the data access methods. BlogRepositoryWithCaching.cs 1: using System; 2: using System.Collections.Generic; 3: using System.Linq; 4: using System.Text; 5:   6: using CacheDiSample.Domain.Model; 7: using CacheDiSample.Domain; 8: using CacheDiSample.Domain.Repositories; 9:   10: namespace CacheDiSample.Domain.CacheDecorators 11: { 12: public class BlogRepositoryWithCaching : IBlogRepository 13: { 14: // The generic cache provider, injected by DI 15: private ICacheProvider<Blog> cacheProvider; 16: // The decorated blog repository, injected by DI 17: private IBlogRepository parentBlogRepository; 18:   19: public BlogRepositoryWithCaching(IBlogRepository parentBlogRepository, ICacheProvider<Blog> cacheProvider) 20: { 21: if (parentBlogRepository == null) 22: throw new ArgumentNullException("parentBlogRepository"); 23:   24: this.parentBlogRepository = parentBlogRepository; 25:   26: if (cacheProvider == null) 27: throw new ArgumentNullException("cacheProvider"); 28:   29: this.cacheProvider = cacheProvider; 30: } 31:   32: public Blog GetByName(string name) 33: { 34: string key = string.Format("CacheDiSample.DataAccess.GetByName.{0}", name); 35: // hard code 5 minute expiry! 36: TimeSpan relativeCacheExpiry = new TimeSpan(0, 5, 0); 37: return cacheProvider.Fetch(key, () => 38: { 39: return parentBlogRepository.GetByName(name); 40: }, 41: null, relativeCacheExpiry); 42: } 43:   44: public Blog GetById(int id) 45: { 46: string key = string.Format("CacheDiSample.DataAccess.GetById.{0}", id); 47:   48: // hard code 5 minute expiry! 49: TimeSpan relativeCacheExpiry = new TimeSpan(0, 5, 0); 50: return cacheProvider.Fetch(key, () => 51: { 52: return parentBlogRepository.GetById(id); 53: }, 54: null, relativeCacheExpiry); 55: } 56:   57: public IList<Blog> GetAll() 58: { 59: string key = string.Format("CacheDiSample.DataAccess.GetAll"); 60:   61: // hard code 5 minute expiry! 62: TimeSpan relativeCacheExpiry = new TimeSpan(0, 5, 0); 63: return cacheProvider.Fetch(key, () => 64: { 65: return parentBlogRepository.GetAll(); 66: }, 67: null, relativeCacheExpiry) 68: .ToList(); 69: } 70: } 71: }   The key things in this caching repository are: I inject into the repository the ICacheProvider<Blog> implementation, via the constructor. This will make the cache provider functionality available to the repository. I inject the parent IBlogRepository implementation (which has the actual data access code), via the constructor. This will allow the methods implemented in the parent to be called if nothing is found in the cache. I override each of the methods implemented in the repository, including those implemented in the generic BaseRepository. Each override of these methods follows the same pattern. It makes a call to the CacheProvider.Fetch method, and passes in the parentBlogRepository implementation of the method as the retrieval method, to be used if nothing is present in the cache. Configuring the Caching Repository in the DI Container The final piece of the jigsaw is to tell Castle Windsor to use the BlogRepositoryWithCaching implementation of IBlogRepository, but to inject the actual Data Access implementation into this decorator. This is easily achieved by modifying the RepositoriesInstaller to use Windsor’s implicit decorator wiring: 1: using Castle.MicroKernel.Registration; 2: using Castle.MicroKernel.SubSystems.Configuration; 3: using Castle.Windsor; 4:   5: using CacheDiSample.Domain.CacheDecorators; 6: using CacheDiSample.Domain.Repositories; 7: using CacheDiSample.DataAccess; 8:   9: namespace CacheDiSample.WindsorInstallers 10: { 11: public class RepositoriesInstaller : IWindsorInstaller 12: { 13: public void Install(IWindsorContainer container, IConfigurationStore store) 14: { 15:   16: // Use Castle Windsor implicit wiring for the block repository decorator 17: // Register the outermost decorator first 18: container.Register(Component.For<IBlogRepository>() 19: .ImplementedBy<BlogRepositoryWithCaching>() 20: .LifestyleTransient()); 21: // Next register the IBlogRepository inmplementation to inject into the outer decorator 22: container.Register(Component.For<IBlogRepository>() 23: .ImplementedBy<BlogRepository>() 24: .LifestyleTransient() 25: .DependsOn(new 26: { 27: nameOrConnectionString = "BloggingContext" 28: })); 29: } 30: } 31: }   This is all that is needed. Now if the consumer of the repository makes a call to the repositories method, it will be routed via the caching mechanism. You can test this by stepping through the code, and seeing that the DataAccess.BlogRepository code is only called if there is no data in the cache, or this has expired. The next step is to add the SQL Cache Dependency support into this pattern, this will be a future post.

  • Array subscript is not an integer

    - by Dimitri
    Hello folks, following this previous question Malloc Memory Corruption in C, now i have another problem. I have the same code. Now I am trying to multiply the values contained in the arrays A * vc and store in res. Then A is set to zero and i do a second multiplication with res and vc and i store the values in A.

  • Selling Federal Enterprise Architecture (EA)

    - by TedMcLaughlan
    Selling Federal Enterprise Architecture A taxonomy of subject areas, from which to develop a prioritized marketing and communications plan to evangelize EA activities within and among US Federal Government organizations and constituents. Any and all feedback is appreciated, particularly in developing and extending this discussion as a tool for use – more information and details are also available. "Selling" the discipline of Enterprise Architecture (EA) in the Federal Government (particularly in non-DoD agencies) is difficult, notwithstanding the general availability and use of the Federal Enterprise Architecture Framework (FEAF) for some time now, and the relatively mature use of the reference models in the OMB Capital Planning and Investment (CPIC) cycles. EA in the Federal Government also tends to be a very esoteric and hard to decipher conversation – early apologies to those who agree to continue reading this somewhat lengthy article. Alignment to the FEAF and OMB compliance mandates is long underway across the Federal Departments and Agencies (and visible via tools like PortfolioStat and ITDashboard.gov – but there is still a gap between the top-down compliance directives and enablement programs, and the bottom-up awareness and effective use of EA for either IT investment management or actual mission effectiveness. "EA isn't getting deep enough penetration into programs, components, sub-agencies, etc.", verified a panelist at the most recent EA Government Conference in DC. Newer guidance from OMB may be especially difficult to handle, where bottom-up input can't be accurately aligned, analyzed and reported via standardized EA discipline at the Agency level – for example in addressing the new (for FY13) Exhibit 53D "Agency IT Reductions and Reinvestments" and the information required for "Cloud Computing Alternatives Evaluation" (supporting the new Exhibit 53C, "Agency Cloud Computing Portfolio"). Therefore, EA must be "sold" directly to the communities that matter, from a coordinated, proactive messaging perspective that takes BOTH the Program-level value drivers AND the broader Agency mission and IT maturity context into consideration. Selling EA means persuading others to take additional time and possibly assign additional resources, for a mix of direct and indirect benefits – many of which aren't likely to be realized in the short-term. This means there's probably little current, allocated budget to work with; ergo the challenge of trying to sell an "unfunded mandate". Also, the concept of "Enterprise" in large Departments like Homeland Security tends to cross all kinds of organizational boundaries – as Richard Spires recently indicated by commenting that "...organizational boundaries still trump functional similarities. Most people understand what we're trying to do internally, and at a high level they get it. The problem, of course, is when you get down to them and their system and the fact that you're going to be touching them...there's always that fear factor," Spires said. It is quite clear to the Federal IT Investment community that for EA to meet its objective, understandable, relevant value must be measured and reported using a repeatable method – as described by GAO's recent report "Enterprise Architecture Value Needs To Be Measured and Reported". What's not clear is the method or guidance to sell this value. In fact, the current GAO "Framework for Assessing and Improving Enterprise Architecture Management (Version 2.0)", a.k.a. the "EAMMF", does not include words like "sell", "persuade", "market", etc., except in reference ("within Core Element 19: Organization business owner and CXO representatives are actively engaged in architecture development") to a brief section in the CIO Council's 2001 "Practical Guide to Federal Enterprise Architecture", entitled "3.3.1. Develop an EA Marketing Strategy and Communications Plan." Furthermore, Core Element 19 of the EAMMF is advised to be applied in "Stage 3: Developing Initial EA Versions". This kind of EA sales campaign truly should start much earlier in the maturity progress, i.e. in Stages 0 or 1. So, what are the understandable, relevant benefits (or value) to sell, that can find an agreeable, participatory audience, and can pave the way towards success of a longer-term, funded set of EA mechanisms that can be methodically measured and reported? Pragmatic benefits from a useful EA that can help overcome the fear of change? And how should they be sold? Following is a brief taxonomy (it's a taxonomy, to help organize SME support) of benefit-related subjects that might make the most sense, in creating the messages and organizing an initial "engagement plan" for evangelizing EA "from within". An EA "Sales Taxonomy" of sorts. We're not boiling the ocean here; the subjects that are included are ones that currently appear to be urgently relevant to the current Federal IT Investment landscape. Note that successful dialogue in these topics is directly usable as input or guidance for actually developing early-stage, "Fit-for-Purpose" (a DoDAF term) Enterprise Architecture artifacts, as prescribed by common methods found in most EA methodologies, including FEAF, TOGAF, DoDAF and our own Oracle Enterprise Architecture Framework (OEAF). The taxonomy below is organized by (1) Target Community, (2) Benefit or Value, and (3) EA Program Facet - as in: "Let's talk to (1: Community Member) about how and why (3: EA Facet) the EA program can help with (2: Benefit/Value)". Once the initial discussion targets and subjects are approved (that can be measured and reported), a "marketing and communications plan" can be created. A working example follows the Taxonomy.

To speak with: a. ...a particular set of System Owners Facing Strategic Change, via mandate (like the "Cloud First" mandate); about... b. ...how the EA program's visible and easily accessible Infrastructure Reference Model (i.e. "IRM" or "TRM"), if updated more completely with current system data, can... c. ...help shed light on ways to mitigate risks and avoid future costs associated with NOT leveraging potentially-available shared services across the enterprise... 2. ....the following Marketing & Communications (Sales) Plan can be constructed: a. Create an easy-to-read "Consequence Model" that illustrates how adoption of a cloud capability (like elastic operational storage) can enable rapid and durable compliance with the mandate – using EA traceability. Traceability might be from the IRM to the ARM (that identifies reusable services invoking the elastic storage), and then to the PRM with performance measures (such as % utilization of purchased storage allocation) included in the OMB Exhibits; and b. Schedule a meeting with the Program Owners, timed during their Acquisition Strategy meetings in response to the mandate, to use the "Consequence Model" for advising them to organize a rapid and relevant RFI solicitation for this cloud capability (regarding alternatives for sourcing elastic operational storage); and c. Schedule a series of short "Discovery" meetings with the system architecture leads (as agreed by the Program Owners), to further populate/validate the "As-Is" models and frame the "To Be" models (via scenarios), to better inform the RFI, obtain the best feedback from the vendor community, and provide potential value for and avoid impact to all other programs and systems. --end example -- Note that communications with the intended audience should take a page out of the standard "Search Engine Optimization" (SEO) playbook, using keywords and phrases relating to "value" and "outcome" vs. "compliance" and "output". Searches in email boxes, internal and external search engines for phrases like "cost avoidance strategies", "mission performance metrics" and "innovation funding" should yield messages and content from the EA team. This targeted, informed, practical sales approach should result in additional buy-in and participation, additional EA information contribution and model validation, development of more SMEs and quick "proof points" (with real-life testing) to bolster the case for EA. The proof point here is a successful, timely procurement that satisfies not only the external mandate and external oversight review, but also meets internal EA compliance/conformance goals and therefore is more transparently useful across the community. In short, if sold effectively, the EA will perform and be recognized. EA won’t therefore be used only for compliance, but also (according to a validated, stated purpose) to directly influence decisions and outcomes.

  • Nested form problem in Rails : NoMethodError in Show

    - by brianheys
    I'm trying to build a simple product backlog application to teach myself Rails. For each product, there can be multiple product backlog entries, so I want to create a product view that shows the product information, all the backlog entries for the product, and includes a nested form for adding more backlog entries. Everything works until I try to add the form to the view, which then results in the following error: NoMethodError in Products#show Showing app/views/products/show.html.erb where line #29 raised: undefined method `pblog_ref' for #<Product:0x10423ba68> Extracted source (around line #29): 26: <%= f.error_messages %> 27: <p> 28: <%= f.label :pblog_ref %><br /> 29: <%= f.text_field :pblog_ref %> 30: </p> 31: <p> 32: <%= f.label :product %><br /> The product view where the problem is reported is as follows (the partial works fine, so I won't include that code): <h1>Showing product</h1> <p> <b>Product ref:</b> <%=h @product.product_ref %> </p> <p> <b>Description:</b> <%=h @product.description %> </p> <p> <b>Owner:</b> <%=h @product.owner %> </p> <p> <b>Status:</b> <%=h @product.status %> </p> <h2>Product backlog</h2> <div id="product-backlog"> <%= render :partial => @product.product_backlogs %> </div> <% form_for(@product, ProductBacklog.new) do |f| %> <%= f.error_messages %> <p> <%= f.label :pblog_ref %><br /> <%= f.text_field :pblog_ref %> </p> <p> <%= f.label :product %><br /> <%= f.text_field :product %> </p> <p> <%= f.label :description %><br /> <%= f.text_field :description %> </p> <p> <%= f.label :owner %><br /> <%= f.text_field :owner %> </p> <p> <%= f.label :status %><br /> <%= f.text_field :status %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> <%= link_to 'Edit', edit_product_path(@product) %> | <%= link_to 'Back', products_path %> This is the Product model: class Product < ActiveRecord::Base validates_presence_of :product_ref, :description, :owner has_many :product_backlogs end This is the ProductBacklog model: class ProductBacklog < ActiveRecord::Base belongs_to :product end These are the routes: map.resources :product_backlogs map.resources :products, :has_many => :product_backlogs I've checked what I'm doing against the Creating a weblog in 15 minutes with Rails 2 screencast, and in principle I seem to be doing the same thing as him - only his nested comments form works, and mine doesn't! I hope someone can help with this, before I turn mad! I'm sure it's something trivial.

  • .NET interview, code structure and the design

    - by j_lewis
    I have been given the below .NET question in an interview. I don’t know why I got low marks. Unfortunately I did not get a feedback. Question: The file hockey.csv contains the results from the Hockey Premier League. The columns ‘For’ and ‘Against’ contain the total number of goals scored for and against each team in that season (so Alabama scored 79 goals against opponents, and had 36 goals scored against them). Write a program to print the name of the team with the smallest difference in ‘for’ and ‘against’ goals. the structure of the hockey.csv looks like this (it is a valid csv file, but I just copied the values here to get an idea) Team - For - Against Alabama 79 36 Washinton 67 30 Indiana 87 45 Newcastle 74 52 Florida 53 37 New York 46 47 Sunderland 29 51 Lova 41 64 Nevada 33 63 Boston 30 64 Nevada 33 63 Boston 30 64 Solution: class Program { static void Main(string[] args) { string path = @"C:\Users\<valid csv path>"; var resultEvaluator = new ResultEvaluator(string.Format(@"{0}\{1}",path, "hockey.csv")); var team = resultEvaluator.GetTeamSmallestDifferenceForAgainst(); Console.WriteLine( string.Format("Smallest difference in ‘For’ and ‘Against’ goals > TEAM: {0}, GOALS DIF: {1}", team.Name, team.Difference )); Console.ReadLine(); } } public interface IResultEvaluator { Team GetTeamSmallestDifferenceForAgainst(); } public class ResultEvaluator : IResultEvaluator { private static DataTable leagueDataTable; private readonly string filePath; private readonly ICsvExtractor csvExtractor; public ResultEvaluator(string filePath){ this.filePath = filePath; csvExtractor = new CsvExtractor(); } private DataTable LeagueDataTable{ get { if (leagueDataTable == null) { leagueDataTable = csvExtractor.GetDataTable(filePath); } return leagueDataTable; } } public Team GetTeamSmallestDifferenceForAgainst() { var teams = GetTeams(); var lowestTeam = teams.OrderBy(p => p.Difference).First(); return lowestTeam; } private IEnumerable<Team> GetTeams() { IList<Team> list = new List<Team>(); foreach (DataRow row in LeagueDataTable.Rows) { var name = row["Team"].ToString(); var @for = int.Parse(row["For"].ToString()); var against = int.Parse(row["Against"].ToString()); var team = new Team(name, against, @for); list.Add(team); } return list; } } public interface ICsvExtractor { DataTable GetDataTable(string csvFilePath); } public class CsvExtractor : ICsvExtractor { public DataTable GetDataTable(string csvFilePath) { var lines = File.ReadAllLines(csvFilePath); string[] fields; fields = lines[0].Split(new[] { ',' }); int columns = fields.GetLength(0); var dt = new DataTable(); //always assume 1st row is the column name. for (int i = 0; i < columns; i++) { dt.Columns.Add(fields[i].ToLower(), typeof(string)); } DataRow row; for (int i = 1; i < lines.GetLength(0); i++) { fields = lines[i].Split(new char[] { ',' }); row = dt.NewRow(); for (int f = 0; f < columns; f++) row[f] = fields[f]; dt.Rows.Add(row); } return dt; } } public class Team { public Team(string name, int against, int @for) { Name = name; Against = against; For = @for; } public string Name { get; private set; } public int Against { get; private set; } public int For { get; private set; } public int Difference { get { return (For - Against); } } } Output: Smallest difference in for' andagainst' goals TEAM: Boston, GOALS DIF: -34 Can someone please review my code and see anything obviously wrong here? They were only interested in the structure/design of the code and whether the program produces the correct result (i.e lowest difference). Much appreciated. "P.S - Please correct me if the ".net-interview" tag is not the right tag to use"

  • I have this broken php upload script

    - by Anders Kitson
    I have this script for uploading a image and content from a form, it works in one project but not the other. I have spent a good few hours trying to debug it, I am hoping someone could point out the issue I might be having. Where there are comments is where I have tried to debug. The first error I got was the "echo invalid file" at the beginning of the last comment. With these specific areas commented out the upload name and type that I am supposed to be grabbing from the form is not being echoed, I am thinking this is where the error is occurring, but can't quite seem to find it. Thanks. <?php include("../includes/connect.php"); /* if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 2000000)) { */ if ($_FILES["file"]["error"] > 0) { echo "Return Code: " . $_FILES["file"]["error"] .

  • Multiplying two matrices from two text files with unknown dimensions

    - by wes schwertner
    This is my first post here. I've been working on this c++ question for a while now and have gotten nowhere. Maybe you guys can give me some hints to get me started. My program has to read two .txt files each containing one matrix. Then it has to multiply them and output it to another .txt file. My confusion here though is how the .txt files are setup and how to get the dimensions. Here is an example of matrix 1.txt. #ivalue #jvalue value 1 1 1.0 2 2 1 The dimension of the matrix is 2x2. 1.0 0 0 1 Before I can start multiplying these matrices I need to get the i and j value from the text file. The only way I have found out to do this is int main() { ifstream file("a.txt"); int numcol; float col; for(int x=0; x<3;x++) { file>>col; cout<<col; if(x==1) //grabs the number of columns numcol=col; } cout<<numcol; } The problem is I don't know how to get to the second line to read the number of rows. And on top of that I don't think this will give me accurate results for other matrices files. Let me know if anything is unclear. UPDATE Thanks! I got getline to work correctly. But now I am running into another problem. In matrix B it is setup like: #ivalue #jvalue Value 1 1 0.1 1 2 0.2 2 1 0.3 2 2 0.4 I need to let the program know that it needs to go down 4 lines, maybe even more (The matrices dimensions are unknown. My matrix B example is a 2x2, but it could be a 20x20). I have a while(!file.eof()) loop my program to let it loop until the end of file. I know I need a dynamic array for multiplying, but would I need one here also? #include <iostream> #include <fstream> using namespace std; int main() { ifstream file("a.txt"); //reads matrix A while(!file.eof()) { int temp; int numcol; string numrow; float row; float col; for(int x=0; x<3;x++) { file>>col; if(x==1) { numcol=col; //number of columns } } string test; getline(file, test); //next line to get rows for(int x=0; x<3; x++) { file>>test; if(x==1) { numrow=test; //sets number of rows } } cout<<numrow; cout<<numcol<<endl; } ifstream file1("b.txt"); //reads matrix 2 while(!file1.eof()) { int temp1; int numcol1; string numrow1; float row1; float col1; for(int x=0; x<2;x++) { file1>>col1; if(x==1) numcol1=col1; //sets number of columns } string test1; getline(file1, test1); //In matrix B there are four rows. getline(file1, test1); //These getlines go down a row. getline(file1, test1); //Need help here. for(int x=0; x<2; x++) { file1>>test1; if(x==1) numrow1=test1; } cout<<numrow1; cout<<numcol1<<endl; } }

  • Polymorphic associations in CakePHP2

    - by Joseph
    I have 3 models, Page , Course and Content Page and Course contain meta data and Content contains HTML content. Page and Course both hasMany Content Content belongsTo Page and Course To avoid having page_id and course_id fields in Content (because I want this to scale to more than just 2 models) I am looking at using Polymorphic Associations. I started by using the Polymorphic Behavior in the Bakery but it is generating waaay too many SQL queries for my liking and it's also throwing an "Illegal Offset" error which I don't know how to fix (it was written in 2008 and nobody seems to have referred to it recently so perhaps the error is due to it not having been designed for Cake 2?) Anyway, I've found that I can almost do everything I need by hardcoding the associations in the models as such: Page Model CREATE TABLE `pages` ( `id` int(11) NOT NULL AUTO_INCREMENT, `title` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `slug` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `created` datetime NOT NULL, `updated` datetime NOT NULL, PRIMARY KEY (`id`) ) <?php class Page extends AppModel { var $name = 'Page'; var $hasMany = array( 'Content' => array( 'className' => 'Content', 'foreignKey' => 'foreign_id', 'conditions' => array('Content.class' => 'Page'), ) ); } ?> Course Model CREATE TABLE `courses` ( `id` int(11) NOT NULL AUTO_INCREMENT, `title` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `slug` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `created` datetime NOT NULL, `updated` datetime NOT NULL, PRIMARY KEY (`id`) ) <?php class Course extends AppModel { var $name = 'Course'; var $hasMany = array( 'Content' => array( 'className' => 'Content', 'foreignKey' => 'foreign_id', 'conditions' => array('Content.class' => 'Course'), ) ); } ?> Content model CREATE TABLE IF NOT EXISTS `contents` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `class` varchar(30) COLLATE utf8_unicode_ci NOT NULL, `foreign_id` int(11) unsigned NOT NULL, `title` varchar(100) COLLATE utf8_unicode_ci NOT NULL, `content` text COLLATE utf8_unicode_ci NOT NULL, `created` datetime DEFAULT NULL, `modified` datetime DEFAULT NULL, PRIMARY KEY (`id`) ) <?php class Content extends AppModel { var $name = 'Content'; var $belongsTo = array( 'Page' => array( 'foreignKey' => 'foreign_id', 'conditions' => array('Content.class' => 'Page') ), 'Course' => array( 'foreignKey' => 'foreign_id', 'conditions' => array('Content.class' => 'Course') ) ); } ?> The good thing is that $this->Content->find('first') only generates a single SQL query instead of 3 (as was the case with the Polymorphic Behavior) but the problem is that the dataset returned includes both of the belongsTo models, whereas it should only really return the one that exists. Here's how the returned data looks: array( 'Content' => array( 'id' => '1', 'class' => 'Course', 'foreign_id' => '1', 'title' => 'something about this course', 'content' => 'The content here', 'created' => null, 'modified' => null ), 'Page' => array( 'id' => null, 'title' => null, 'slug' => null, 'created' => null, 'updated' => null ), 'Course' => array( 'id' => '1', 'title' => 'Course name', 'slug' => 'name-of-the-course', 'created' => '2012-10-11 00:00:00', 'updated' => '2012-10-11 00:00:00' ) ) I only want it to return one of either Page or Course depending on which one is specified in Content.class UPDATE: Combining the Page and Course models would seem like the obvious solution to this problem but the schemas I have shown above are just shown for the purpose of this question. The actual schemas are actually very different in terms of their fields and the each have a different number of associations with other models too. UPDATE 2 Here is the query that results from running $this->Content->find('first'); : SELECT `Content`.`id`, `Content`.`class`, `Content`.`foreign_id`, `Content`.`title`, `Content`.`slug`, `Content`.`content`, `Content`.`created`, `Content`.`modified`, `Page`.`id`, `Page`.`title`, `Page`.`slug`, `Page`.`created`, `Page`.`updated`, `Course`.`id`, `Course`.`title`, `Course`.`slug`, `Course`.`created`, `Course`.`updated` FROM `cakedb`.`contents` AS `Content` LEFT JOIN `cakedb`.`pages` AS `Page` ON (`Content`.`foreign_id` = `Page`.`id` AND `Content`.`class` = 'Page') LEFT JOIN `cakedb`.`courses` AS `Course` ON (`Content`.`foreign_id` = `Course`.`id` AND `Content`.`class` = 'Course') WHERE 1 = 1 LIMIT 1

What one can do, is: in one terminal, run the server and read (through cat) its write pipe: :~$ ./fd_server & 2/dev/null [1] 11354 :~$ cat /tmp/np2 and in another, write (using echo) to server's read pipe: :~$ echo "heeellloooo" /tmp/np1 going back to first terminal, one can see: :~$ cat /tmp/np2 HEEELLLOOOO 0[1]+ Exit 13 ./fd_server 2 /dev/null What I would like to do, is make sort of a "interactive" (or "shell"-like) session; that is, the server is run as usual, but instead of running "cat" and "echo", I'd like to use something akin to screen. What I mean by that, is that screen can be called like screen /dev/ttyS0 38400, and then it makes a sort of a interactive session, where what is typed in terminal is passed to /dev/ttyS0, and its response is written to terminal. Now, of course, I cannot use screen, because in my case the program has two separate nodes, and as far as I can tell, screen can refer to only one. How would one go about to achieve this sort of "interactive" session in this context (with two separate read/write pipes)? Thanks, Cheers! Code below: #include <stdio.h> #include <errno.h> #include <ctype.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> //#include <fullduplex.h> /* For name of the named-pipe */ #define NP1 "/tmp/np1" #define NP2 "/tmp/np2" #define MAX_BUF_SIZE 255 #include <stdlib.h> //exit #include <string.h> //strlen int main(int argc, char *argv[]) { int rdfd, wrfd, ret_val, count, numread; char buf[MAX_BUF_SIZE]; /* Create the first named - pipe */ ret_val = mkfifo(NP1, 0666); if ((ret_val == -1) && (errno != EEXIST)) { perror("Error creating the named pipe"); exit (1); } ret_val = mkfifo(NP2, 0666); if ((ret_val == -1) && (errno != EEXIST)) { perror("Error creating the named pipe"); exit (1); } /* Open the first named pipe for reading */ rdfd = open(NP1, O_RDONLY); /* Open the second named pipe for writing */ wrfd = open(NP2, O_WRONLY); /* Read from the first pipe */ numread = read(rdfd, buf, MAX_BUF_SIZE); buf[numread] = '0'; fprintf(stderr, "Full Duplex Server : Read From the pipe : %sn", buf); /* Convert to the string to upper case */ count = 0; while (count < numread) { buf[count] = toupper(buf[count]); count++; } /* * Write the converted string back to the second * pipe */ write(wrfd, buf, strlen(buf)); } Edit: Right, just to clarify - it seems I found a document discussing something very similar, it is http://en.wikibooks.org/wiki/Serial_Programming/Serial_Linux#Configuration_with_stty - a modification of the script there ("For example, the following script configures the device and starts a background process for copying all received data from the serial device to standard output...") for the above program is below: # stty raw # ( ./fd_server 2>/dev/null; )& bgPidS=$! ( cat < /tmp/np2 ; )& bgPid=$! # Read commands from user, send them to device echo $(kill -0 $bgPidS 2>/dev/null ; echo $?) while [ "$(kill -0 $bgPidS 2>/dev/null ; echo $?)" -eq "0" ] && read cmd; do # redirect debug msgs to stderr, as here we're redirected to /tmp/np1 echo "$? - $bgPidS - $bgPid" >&2 echo "$cmd" echo -e "\nproc: $(kill -0 $bgPidS 2>/dev/null ; echo $?)" >&2 done >/tmp/np1 echo OUT # Terminate background read process - if they still exist if [ "$(kill -0 $bgPid 2>/dev/null ; echo $?)" -eq "0" ] ; then kill $bgPid fi if [ "$(kill -0 $bgPidS 2>/dev/null ; echo $?)" -eq "0" ] ; then kill $bgPidS fi # stty cooked So, saving the script as say starter.sh and calling it, results with the following session: $ ./starter.sh 0 i'm typing here and pressing [enter] at end 0 - 13496 - 13497 I'M TYPING HERE AND PRESSING [ENTER] AT END 0~?.N=?(?~? ?????}????@??????~? [garble] proc: 0 OUT which is what I'd call for "interactive session" (ignoring the debug statements) - server waits for me to enter a command; it gives its output after it receives a command (and as in this case it exits after first command, so does the starter script as well). Except that, I'd like to not have buffered input, but sent character by character (meaning the above session should exit after first key press, and print out a single letter only - which is what I expected stty raw would help with, but it doesn't: it just kills reaction to both Enter and Ctrl-C :) ) I was just wandering if there already is an existing command (akin to screen in respect to serial devices, I guess) that would accept two such named pipes as arguments, and establish a "terminal" or "shell" like session through them; or would I have to use scripts as above and/or program own 'client' that will behave as a terminal..

  • Optimizing python code performance when importing zipped csv to a mongo collection

    - by mark
    I need to import a zipped csv into a mongo collection, but there is a catch - every record contains a timestamp in Pacific Time, which must be converted to the local time corresponding to the (longitude,latitude) pair found in the same record. The code looks like so: def read_csv_zip(path, timezones): with ZipFile(path) as z, z.open(z.namelist()[0]) as input: csv_rows = csv.reader(input) header = csv_rows.next() check,converters = get_aux_stuff(header) for csv_row in csv_rows: if check(csv_row): row = { converter[0]:converter[1](value) for converter, value in zip(converters, csv_row) if allow_field(converter) } ts = row['ts'] lng, lat = row['loc'] found_tz_entry = timezones.find_one(SON({'loc': {'$within': {'$box': [[lng-tz_lookup_radius, lat-tz_lookup_radius],[lng+tz_lookup_radius, lat+tz_lookup_radius]]}}})) if found_tz_entry: tz_name = found_tz_entry['tz'] local_ts = ts.astimezone(timezone(tz_name)).replace(tzinfo=None) row['tz'] = tz_name else: local_ts = (ts.astimezone(utc) + timedelta(hours = int(lng/15))).replace(tzinfo = None) row['local_ts'] = local_ts yield row def insert_documents(collection, source, batch_size): while True: items = list(itertools.islice(source, batch_size)) if len(items) == 0: break; try: collection.insert(items) except: for item in items: try: collection.insert(item) except Exception as exc: print("Failed to insert record {0} - {1}".format(item['_id'], exc)) def main(zip_path): with Connection() as connection: data = connection.mydb.data timezones = connection.timezones.data insert_documents(data, read_csv_zip(zip_path, timezones), 1000) The code proceeds as follows: Every record read from the csv is checked and converted to a dictionary, where some fields may be skipped, some titles be renamed (from those appearing in the csv header), some values may be converted (to datetime, to integers, to floats. etc ...) For each record read from the csv, a lookup is made into the timezones collection to map the record location to the respective time zone. If the mapping is successful - that timezone is used to convert the record timestamp (pacific time) to the respective local timestamp. If no mapping is found - a rough approximation is calculated. The timezones collection is appropriately indexed, of course - calling explain() confirms it. The process is slow. Naturally, having to query the timezones collection for every record kills the performance. I am looking for advises on how to improve it. Thanks. EDIT The timezones collection contains 8176040 records, each containing four values: > db.data.findOne() { "_id" : 3038814, "loc" : [ 1.48333, 42.5 ], "tz" : "Europe/Andorra" } EDIT2 OK, I have compiled a release build of http://toblerity.github.com/rtree/ and configured the rtree package. Then I have created an rtree dat/idx pair of files corresponding to my timezones collection. So, instead of calling collection.find_one I call index.intersection. Surprisingly, not only there is no improvement, but it works even more slowly now! May be rtree could be fine tuned to load the entire dat/idx pair into RAM (704M), but I do not know how to do it. Until then, it is not an alternative. In general, I think the solution should involve parallelization of the task.

  • Help Writing Input Data to Database With Wordpress Plugin

    Hi I am making a wordpress plugin where I need the Admin to enter data into a database table.

  • Patching this Code to apply dynamic (iPhone) background position

    - by Brian
    I posted a question previously that got off topic, I'm reposting with better code that I have VERIFIED is compatible with iPhone (it works with mine anyway!) I just want to apply background-position coordinates to the body element and call the script conditionally for iPhone, iPod, & iPad. Here's my conditional call for those devices: var deviceAgent = navigator.userAgent.toLowerCase(); var agentID = deviceAgent.match(/(iphone|ipod|ipad)/); if (agentID) { // do something } else { //do this } Now, I've found this excellent script that sets the "top: x" dynamically on the basis of scroll position. Everyone has told me (and ALL of the tutorials and Google search results as well) that it's impossible to set scroll position dynamically for iPhone because of the viewport issue. HOWEVER, they are wrong because if you scroll to the bottom of the page and view this javascript demo on iPhone, you can scroll and the <div style="background-position: fixed; top: x (variable)"></div> div DOES stay centered on iPhone. I really hope this question helps alot of people, I thought it was impossible, but it's NOT... I just need help stitching it together! The original code (you can test it on iPhone yourself) is here: http://stevenbenner.com/2010/04/calculate-page-size-and-view-port-position-in-javascript/ So I just need help getting the following code to apply the dynamic "background-position: 0 x" to the BODY tag where x is centered and relative to the viewport position. Also, needs to be nested inside the above code that is conditional for iPhone and similar devices. // Page Size and View Port Dimension Tools // http://stevenbenner.com/2010/04/calculate-page-size-and-view-port-position-in-javascript/ if (!sb_windowTools) { var sb_windowTools = new Object(); }; sb_windowTools = { scrollBarPadding: 17, // padding to assume for scroll bars // EXAMPLE METHODS // center an element in the viewport centerElementOnScreen: function(element) { var pageDimensions = this.updateDimensions(); element.style.top = ((this.pageDimensions.verticalOffset() + this.pageDimensions.windowHeight() / 2) - (this.scrollBarPadding + element.offsetHeight / 2)) + 'px'; element.style.left = ((this.pageDimensions.windowWidth() / 2) - (this.scrollBarPadding + element.offsetWidth / 2)) + 'px'; element.style.position = 'absolute'; }, // INFORMATION GETTERS // load the page size, view port position and vertical scroll offset updateDimensions: function() { this.updatePageSize(); this.updateWindowSize(); this.updateScrollOffset(); }, // load page size information updatePageSize: function() { // document dimensions var viewportWidth, viewportHeight; if (window.innerHeight && window.scrollMaxY) { viewportWidth = document.body.scrollWidth; viewportHeight = window.innerHeight + window.scrollMaxY; } else if (document.body.scrollHeight > document.body.offsetHeight) { // all but explorer mac viewportWidth = document.body.scrollWidth; viewportHeight = document.body.scrollHeight; } else { // explorer mac...would also work in explorer 6 strict, mozilla and safari viewportWidth = document.body.offsetWidth; viewportHeight = document.body.offsetHeight; }; this.pageSize = { viewportWidth: viewportWidth, viewportHeight: viewportHeight }; }, // load window size information updateWindowSize: function() { // view port dimensions var windowWidth, windowHeight; if (self.innerHeight) { // all except explorer windowWidth = self.innerWidth; windowHeight = self.innerHeight; } else if (document.documentElement && document.documentElement.clientHeight) { // explorer 6 strict mode windowWidth = document.documentElement.clientWidth; windowHeight = document.documentElement.clientHeight; } else if (document.body) { // other explorers windowWidth = document.body.clientWidth; windowHeight = document.body.clientHeight; }; this.windowSize = { windowWidth: windowWidth, windowHeight: windowHeight }; }, // load scroll offset information updateScrollOffset: function() { // viewport vertical scroll offset var horizontalOffset, verticalOffset; if (self.pageYOffset) { horizontalOffset = self.pageXOffset; verticalOffset = self.pageYOffset; } else if (document.documentElement && document.documentElement.scrollTop) { // Explorer 6 Strict horizontalOffset = document.documentElement.scrollLeft; verticalOffset = document.documentElement.scrollTop; } else if (document.body) { // all other Explorers horizontalOffset = document.body.scrollLeft; verticalOffset = document.body.scrollTop; }; this.scrollOffset = { horizontalOffset: horizontalOffset, verticalOffset: verticalOffset }; }, // INFORMATION CONTAINERS // raw data containers pageSize: {}, windowSize: {}, scrollOffset: {}, // combined dimensions object with bounding logic pageDimensions: { pageWidth: function() { return sb_windowTools.pageSize.viewportWidth > sb_windowTools.windowSize.windowWidth ? sb_windowTools.pageSize.viewportWidth : sb_windowTools.windowSize.windowWidth; }, pageHeight: function() { return sb_windowTools.pageSize.viewportHeight > sb_windowTools.windowSize.windowHeight ? sb_windowTools.pageSize.viewportHeight : sb_windowTools.windowSize.windowHeight; }, windowWidth: function() { return sb_windowTools.windowSize.windowWidth; }, windowHeight: function() { return sb_windowTools.windowSize.windowHeight; }, horizontalOffset: function() { return sb_windowTools.scrollOffset.horizontalOffset; }, verticalOffset: function() { return sb_windowTools.scrollOffset.verticalOffset; } } };

Could anyone point out the mistake i made? http://uva.onlinejudge.org/index.php?option=com_onlinejudge&Itemid=8&page=show_problem&problem=985 Here is the code import java.util.*; import java.io.*; class Main { private String inputLines[]; private String namesToBeFound[]; private String namesInEachBook[][]; private String searchItem; private boolean solnfound=false; private static final BufferedReader br =new BufferedReader(new InputStreamReader(System.in)); static String read() throws IOException { String line; while(true) { line=br.readLine(); if(line==null) break; //eof else if(line.length()==0) continue; //blank line else { line=line.trim().replaceAll("\\s+"," "); return line; } } return null; } public static void main(String args[]) throws IOException { Main ob=new Main(); int totalPapers,calcAuthors,totalScenarios; //First input number of scenarios totalScenarios=Integer.parseInt(read()); //Now start a loop for reading total number of scenarios for(int scenario=1;scenario<=totalScenarios;scenario++) { //Now read the line containing the number of papers and authors StringTokenizer line=new StringTokenizer(read()," "); totalPapers=Integer.parseInt(line.nextToken()); calcAuthors=Integer.parseInt(line.nextToken()); //Read a line containing author names along with book names ob.inputLines=new String[totalPapers]; for(int i=0;i<totalPapers;i++) ob.inputLines[i]=read(); //Read a line containing the names to be searched ob.namesToBeFound=new String[calcAuthors]; for(int i=0;i<calcAuthors;i++) ob.namesToBeFound[i]=read(); //Now generate the array ob.buildArray(); //Now search System.out.println("Scenario "+scenario); for(int i=0;i<calcAuthors;i++) { ob.searchItem=ob.namesToBeFound[i]; if(ob.searchItem.equals("Erdos, P.")) { System.out.println("Erdos, P. 0"); continue; } ob.search(ob.namesToBeFound[i],1,new ArrayList()); if(ob.solnfound==false) System.out.println(ob.searchItem+" infinity"); ob.solnfound=false; } } } private void buildArray() { String str; namesInEachBook=new String[inputLines.length][]; for(int i=0;i<inputLines.length;i++) { str=inputLines[i]; str=str.substring(0,str.indexOf(':')); str+=","; namesInEachBook[i]=new String[(countCommas(str)+1)>>1]; for(int j=0;j<namesInEachBook[i].length;j++) { str=str.trim(); namesInEachBook[i][j]=""; namesInEachBook[i][j]+=str.substring(0,str.indexOf(','))+","; str=str.substring(str.indexOf(',')+1); namesInEachBook[i][j]+=str.substring(0,str.indexOf(',')); str=str.substring(str.indexOf(',')+1); } } } private int countCommas(String s) { int num=0; for(int i=0;i<s.length();i++) if(s.charAt(i)==',') num++; return num; } private void search(String searchElem,int ernosDepth,ArrayList searchedElem) { ArrayList searchSpace=new ArrayList(); searchedElem.add(searchElem); for(int i=0;i<namesInEachBook.length;i++) for(int j=0;j<namesInEachBook[i].length;j++) { if(namesInEachBook[i][j].equals(searchElem)) //Add all authors name in this group { for(int k=0;k<namesInEachBook[i].length;k++) { if(namesInEachBook[i][k].equals("Erdos, P.")) //Found { solnfound=true; System.out.println(searchItem+" "+ernosDepth); return; } else if(searchedElem.contains(namesInEachBook[i][k]) || searchSpace.contains(namesInEachBook[i][k])) continue; searchSpace.add(namesInEachBook[i][k]); } break; } } Iterator i=searchSpace.iterator(); while(i.hasNext()) { String cSearchElem=(String)i.next(); search(cSearchElem,ernosDepth+1,searchedElem); } } }
