  • Java: Reading a pdf file from URL into Byte array/ByteBuffer in an applet.

    - by Pol
    I'm trying to figure out why this particular snippet of code isn't working for me. I've got an applet which is supposed to read a .pdf and display it with a pdf-renderer library, but for some reason when I read in the .pdf files which sit on my server, they end up as being corrupt. I've tested it by writing the files back out again. I've tried viewing the applet in both IE and Firefox and the corrupt files occur. Funny thing is, when I trying viewing the applet in Safari (for Windows), the file is actually fine! I understand the JVM might be different, but I am still lost. I've compiled in Java 1.5. JVMs are 1.6. The snippet which reads the file is below. public static ByteBuffer getAsByteArray(URL url) throws IOException { ByteArrayOutputStream tmpOut = new ByteArrayOutputStream(); URLConnection connection = url.openConnection(); int contentLength = connection.getContentLength(); InputStream in = url.openStream(); byte[] buf = new byte[512]; int len; while (true) { len = in.read(buf); if (len == -1) { break; } tmpOut.write(buf, 0, len); } tmpOut.close(); ByteBuffer bb = ByteBuffer.wrap(tmpOut.toByteArray(), 0, tmpOut.size()); //Lines below used to test if file is corrupt //FileOutputStream fos = new FileOutputStream("C:\\abc.pdf"); //fos.write(tmpOut.toByteArray()); return bb; } I must be missing something, and I've been banging my head trying to figure it out. Any help is greatly appreciated. Thanks. Edit: To further clarify my situation, the difference in the file before I read then with the snippet and after, is that the ones I output after reading are significantly smaller than they originally are. When opening them, they are not recognized as .pdf files. There are no exceptions being thrown that I ignore, and I have tried flushing to no avail. This snippet works in Safari, meaning the files are read in it's entirety, with no difference in size, and can be opened with any .pdf reader. In IE and Firefox, the files always end up being corrupted, consistently the same smaller size. I monitored the len variable (when reading a 59kb file), hoping to see how many bytes get read in at each loop. In IE and Firefox, at 18kb, the in.read(buf) returns a -1 as if the file has ended. Safari does not do this. I'll keep at it, and I appreciate all the suggestions so far.

  • JPopupMenu returning a null?

    - by Zenzen
    Ok so I'm working on an Eclipse plugin based on the JGraph example. The problem is I can't really get the "save" method to work, here's how the program works in short: - I have a DiagramEditor class with an init() method, where I create a GraphEditor object and call the createFrame() methord of that object. - GraphEditor extends the BasicGraphEditor (which extends JPanel), the createFrame() method returns a JFrame and has a line "frame.setJMenuBar(menuBar)" - the "menuBar" is an object variable, which is initialized in the BasicGraphEditor. Till here everything is cool, the problem is with the action listener which is supposed to save a file. To get the graph I need to get the GraphEditor component, so I do a Component component = (Component) e.getSource() whitch is the ActionEvent passed to that action listener and at that stage is the JMenuItem "save", then I get the parent which is the JPopupMenu, then I want to get that JPopupMenu's parent which should be the GraphEdiotor, but instead I get a null. Any idea why? Here's some source code: DiagramEditor.java: @Override public void init(IEditorSite site, IEditorInput input) throws PartInitException { setSite(site); setInput(input); this.diagram = ((DiagramEditorInput)input).getDiagram(); setPartName(this.diagram.getName()); gEditor = new GraphEditor(); gEditor.createFrame().setVisible(true); } BasicGraphEditor.java: public JFrame createFrame() { JFrame frame = new JFrame(); frame.getContentPane().add(this); frame.setJMenuBar(menuBar); //frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(870, 640); return frame; } In the constructor: menuBar = new JMenuBar(); menu = new JMenu("File"); menu.setMnemonic(KeyEvent.VK_F); menuBar.add(menu); JMenuItem openMenuItem = new JMenuItem("Open", KeyEvent.VK_O); // ADD FILE OPENING //openMenuItem.addActionListener(menuListener); menu.add(openMenuItem); JMenuItem saveMenuItem = new JMenuItem("Save", new ImageIcon("/images/save.gif")); saveMenuItem.setMnemonic(KeyEvent.VK_S); saveMenuItem.addActionListener( new SaveAction(false) ); menu.add(saveMenuItem); // menu.add(new SaveAction(false)); JMenuItem saveMenuItemAs = new JMenuItem("SaveAs", new ImageIcon("/images/saveas.gif")); //saveMenuItemAs.setMnemonic(KeyEvent.VK_S); saveMenuItemAs.addActionListener( new SaveAction(true) ); menu.add(saveMenuItemAs); //menu.add(new SaveAction(true)); JMenuItem closeMenuItem = new JMenuItem("Close", KeyEvent.VK_C); closeMenuItem.addActionListener( new ActionListener() { public void actionPerformed(ActionEvent e) { System.exit(0); } } ); menu.add(closeMenuItem);

  • Best Practice: Legitimate Cross-Site Scripting

    - by Ryan
    While cross-site scripting is generally regarded as negative, I've run into several situations where it's necessary. I was recently working within the confines of a very limiting content management system. I needed to include database code within the page, but the hosting server didn't have anything usable available. I set up a couple barebones scripts on my own server, originally thinking that I could use AJAX to import the contents of my scripts directly into the template of the CMS (thus retaining dynamic images, menu items, CSS, etc.). I was wrong. Due to the limitations of XMLHttpRequest objects, it's not possible to grab content from a different domain. So I thought "iFrame" - even though I'm not a fan of frames, I thought that I could create a frame that matched the width and height of the content, so that it would appear native. Again, I was blocked by cross-site scripting "protections." While I could indeed load a remote file into the iFrame, I couldn't execute JavaScript to modify its size on either the host page or inside the loaded page. In this particular scenario, I wasn't able to point a subdomain to my server. I also couldn't create a script on the CMS server that could proxy content from my server, so my last thought was to use a remote JavaScript. A remote JavaScript works. It breaks when the user has JavaScript disabled, which is a downside; but it works. The "problem" I was having with using a remote JavaScript was that I had to use the JS function document.write() to output any content. Any output that isn't JS causes script errors. In addition to using document.write() for every line, you also have to ensure that the content is escaped - or else you end up with more script errors. My solution was as follows: My script received a GET parameter ("page") and then looked for the file ({$page}.php), and read the contents into a variable. However, I had to use awkward buffering techniques in order to actually execute the included scripts (for things like database interaction) then strip the final content of all line break characters ("\n") followed by escaping all required characters. The end result is that my original script (which outputs JavaScript) accesses seemingly "standard" scripts on my server and converts their standard output to JavaScript for displaying within the CMS template. While this solution works, it seems like there may be a better way to accomplish the same thing. What is the best way to make cross-site scripting work specifically for the purpose of including content from a completely different domain?

  • jquery ajax error cannot find url outside of debug mode

    - by John Orlandella Jr.
    I inherited some code two weeks ago that is using the jquery.ajax method to connect to a .NET web service. Here is the piece of code give me the trouble... if (MSCTour.AppSettings.OFFLINE !== 'TRUE') { $.ajax({ url: url, data: json, type: "POST", contentType: "application/json", timeout: 10000, dataType: "json", // not "json" we'll parse success: function(res){ if (!callback) { return; } /* // *** Use json library so we can fix up MS AJAX dates */ var result = ""; if (res !== "") { try { result = $.evalJSON(res); } catch (e) { result = {}; bare = true; } } /* // *** Bare message IS result */ if (bare) { callback(result); return; } /* // *** Wrapped message contains top level object node // *** strip it off */ for (var property in result) { callback(result[property]); break; } }, error: function(xhr,status,error){ if (status === 'parsererror') {} else {return error;} }, complete: function(res, status){ if (callback) { if ((status != 'success' && status != 'error') || status === 'parsererror' || (status === 'timeout' && res !== '')) { try { result = $.secureEvalJSON(res); } catch (e) { result = {}; bare = true; } callback(res); } } return; } }); } The url variable at this point equals /testsite/service.svc/GetItems Now here is where my problem lies... When running this site out of debug mode through visual studio I am not having any problem connecting to the database through the web service and seeing all my data, for both viewing and updating. When I go through the normal web server for the same site, on the same page, no data is showing up. When I put a break on the error portion of the code above in firebug this is information I am getting in the image linked below. link text I am getting what appears to be a 404 error, but when I look on the server all of the files are in the right place... coupled with the fact that it works when in debug mode, I think I am slowly going crazy staring at these same lines of code trying to find the needle in the haystack. Any help or just a direction to look in would be greatly appreciated.

  • Including hibernate jar dependencies in ant build

    - by Patrick
    Hi, I'm trying to compile a runnable jar-file for a project that makes use of hibernate. I'm trying to construct an ant build.xml file to streamline my build process, but I'm having troubles with the inclusion of the hibernate3.jar inside the final jar-file. If I run the ant script I manage to include all my library jars, and they are put in the final jar-file's root. When I run the jar-file I get a java.lang.NoClassDefFoundError: org/hibernate/Session error. If I make use of the built-in export to jar in Eclipse, it works only if I choose "extract required libraries into jar". But that bloats the jar, and includes too much of my project (i.e. unit tests). Below is my generated manifest: Manifest-Version: 1.0 Main-Class: main.ServerImpl Class-Path: ./ antlr-2.7.6.jar commons-collections-3.1.jar dom4j-1.6.1.jar hibernate3.jar javassist-3.9.0.GA.jar jta-1.1.jar slf4j-api-1.5.11.jar slf4j-simple-1.5.11.jar mysql-connector-java-5.1.12-bin.jar rmiio-2.0.2.jar commons-logging-1.1.1.jar And the part of the build.xml looks like this: <target name="dist" depends="compile" description="Generates the Distribution Jar(s)"> <mkdir dir="${dist.dir}" /> <jar destfile="${dist.dir}/${dist.file.name}.jar" basedir="${build.prod.dir}" filesetmanifest="mergewithoutmain"> <manifest> <attribute name="Main-Class" value="${main.class}" /> <attribute name="Class-Path" value="./ ${manifest.classpath} " /> <attribute name="Implementation-Title" value="${app.name}" /> <attribute name="Implementation-Version" value="${app.version}" /> <attribute name="Implementation-Vendor" value="${app.vendor}" /> </manifest> <zipfileset refid="hibernatefiles" /> <zipfileset refid="slf4jfiles" /> <zipfileset refid="mysqlfiles" /> <zipfileset refid="commonsloggingfiles" /> <zipfileset refid="rmiiofiles" /> </jar> </target> The refids' for the zipfilesets point to the directories in a library directory lib in the root of the project. The manifest.classpath-variable takes the classpath of all those library jar-files, and flattens them with pathconvert and mapper. I've also tried to set the manifest classpath to ".", "./" and only the library jar, but to no difference at all. I'm hoping there's a simple remedy to my problems...

  • How can i use a duration setting on .animate if it is inside the callback from a .fadeOut effect?

    - by Jannis
    I am trying to just fade the content of section#secondary out and once the content has been faded out, the parent (section#secondary) should animate 'shut' in a slider animation. All this is working however the durations are not and I cannot figure out why. Here is my code: HTML <section id="secondary"> <a href="#" class="slide_button">&laquo;</a> <!-- slide in/back button --> <article> <h1>photos</h1> <div class="album_nav"><a href="#">photo 1 of 6</a> | <a href="#">create an album</a></div> <div class="bar"> <p class="section_title">current image title</p> </div> <section class="image"> <div class="links"> <a class="_back album_link" href="#">« from the album: james new toy</a> <nav> <a href="#" class="_back small_button">back</a> <a href="#" class="_next small_button">next</a> </nav> </div> <img src="http://localhost/~jannis/3781_doggie_wonderland/www/preview/static/images/sample-image-enlarged.jpg" width="418" height="280" alt="" /> </section> </article> <footer> <embed src="http://localhost/~jannis/3781_doggie_wonderland/www/preview/static/flash/secondary-footer.swf" wmode="transparent" width="495" height="115" type="application/x-shockwave-flash" /> </footer> </section> <!-- close secondary --> jQuery // ============================= // = Close button (slide away) = // ============================= $('a.slide_button').click(function() { $(this).closest('section#secondary').children('*').fadeOut('slow', function() { $('section#secondary').animate({'width':'0'}, 3000); }); }); Because the content of section#secondary is variable I use the * selector. What happens is that the fadeOut uses the appropriate slow speed but as soon as the callback fires (once the content is faded out) the section#secondary animates to width: 0 within a couple of milliseconds and not the 3000 ms ( 3 sec ) I set the animation duration to. Any ideas would be appreciated. PS: I cannot post an example at this point but since this is more a matter of theory of jQuery I don't think an example is necessary here. Correct me if I am wrong..

  • ArgumentNullException when accessing a FormView instance

    - by David
    Background: I have an ASP.NET page which has a numebr of user controls within it. There are 2 user controls which are of interest. I need to display either one of them or neither of them, depending on the record selected previously. In the user controls I need to set properties of some controls which are in a FormView. So in my user control code-behind I have a number of properties which look something like this: Private ReadOnly Property phSectionReports() As PlaceHolder Get Return fvConfirmationReport.FindControl("phSectionReports") End Get End Property The problem: I am having problems with this Property. Sometimes it is returning Nothing/Null and sometimes it is throwing a NullArgumentException with the message "Value cannot be null. Parameter name: container". The exception is coming from trying to reference the fvConfirmationReport variable. fvConfirmationReport is the ID of my FormView in the page itself. So I am really after things to look for and if any ideas what sort of conditions (e.g stage in page cycle, etc.) might lead to this? An example stack trace is included below.

  • Apple Push Notifications With Foreign Accent Characters Not Receiving

    - by confeng
    I'm sending push notifications and when the message contains foreign characters (Turkish in my case) like I, s, ç, g... The message does not arrive to devices. Here's my code: $message = 'THIS is push'; $passphrase = 'mypass'; $ctx = stream_context_create(); stream_context_set_option($ctx, 'ssl', 'local_cert', 'MyPemFile.pem'); stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase); // Open a connection to the APNS server $fp = stream_socket_client( 'ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx); if (!$fp) exit("Failed to connect: $err $errstr" . PHP_EOL); echo 'Connected to Apple service. ' . PHP_EOL; // Encode the payload as JSON $body['aps'] = array( 'alert' => $message, 'sound' => 'default' ); $payload = json_encode($body); $result = 'Start'.PHP_EOL; $tokenArray = array('mytoken'); foreach ($tokenArray as $item) { // Build the binary notification $msg = chr(0) . pack('n', 32) . pack('H*', $item) . pack('n', strlen($payload)) . $payload; // Send it to the server $result = fwrite($fp, $msg, strlen($msg)); if (!$result) echo 'Failed message'.PHP_EOL; else echo 'Successful message'.PHP_EOL; } // Close the connection to the server fclose($fp); I have tried encoding $message variable with utf8_encode() but the message received as "THÝS is push". And other ways like iconv() didn't work for me, some of them cropped Turkish characters, some didn't receive at all. I also have header('content-type: text/html; charset: utf-8'); and <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> in my page. I don't think the problem appears while I set the value but maybe with pack() function. Any ideas to solve this without replacing characters with English?

  • DOM memory issue with IE8 (inserting lots of JSON data)

    - by okie.floyd
    i am developing a small web-utility that displays some data from some database tables. i have the utility running fine on FF, Safari, Chrome..., but the memory management on IE8 is horrendous. the largest JSON request I do will return information to create around 5,000 or so rows in a table within the browser (3 columns in the table). i'm using jquery to get the data (via getJSON). to remove the old/existing table, i'm just doing a $('#my_table_tbody').empty(). to add the new info to the table, within the getJSON callback, i am just appending each table row that i am creating to a variable, and then once i have them all, i am using $('#my_table_tbody').append(myVar) to add it to the existing tbody. i don't add the table rows as they are created because that seems to be a lot slower than just adding them all at once. does anyone have any recommendation on what someone should do who is trying to add thousands of rows of data to the DOM? i would like to stay away from pagination, but i'm wondering if i don't have a choice. Update 1 So here is the code I was trying after the innerHTML suggestion: /* Assuming a div called 'main_area' holds the table */ document.getElementById('main_area').innerHTML = ''; $.getJSON("my_server", {my: JSON, args: are, in: here}, function(j) { var mylength = j.length; var k =0; var tmpText = ''; tmpText += /* Add the table, thead stuff, and tbody tags here */; for (k = mylength - 1; k = 0; k--) { /* stack overflow wont let me type greater than & less than signs here, so just assume that they are there. */ tmpText += 'tr class="' + j[k].row_class . '" td class="col1_class" ' + j[k].col1 + ' /td td class="col2_class" ' + j[k].col2 + ' /td td class="col3_class" ' + j[k].col3 + ' /td /tr'; } document.getElementById('main_area').innerHTML = tmpText; } That is the gist of it. I've also tried using just a $.get request, and having the server send the formatted HTML, and just setting that in the innerHTML (i.e. document.getElementById('main_area').innerHTML = j;). thanks for all of the replies. i'm floored with the fact that you all are willing to help.

  • Copy android.R.layout to my project

    - by eric
    Good advice from CommonWare and Steve H but it's not as easy to me as I first thought. Based on their advice I'm trying to copy android.R.layout to my project to ensure consistency. How do you do this? I looked in Eclipse's Package Explorer and under Android 1.5android.jarandroidR.classRlayout and find R$layout.class. Do I copy the code out of there into my own class? From my very limited knowledge of Java, the following code doesn't make much sense: public static final class android.R$layout { // Field descriptor #8 I public static final int activity_list_item = 17367040; // Field descriptor #8 I public static final int browser_link_context_header = 17367054; // Field descriptor #8 I public static final int expandable_list_content = 17367041; // Field descriptor #8 I public static final int preference_category = 17367042; // Field descriptor #8 I public static final int select_dialog_item = 17367057; // Field descriptor #8 I public static final int select_dialog_multichoice = 17367059; // Field descriptor #8 I public static final int select_dialog_singlechoice = 17367058; // Field descriptor #8 I public static final int simple_dropdown_item_1line = 17367050; // Field descriptor #8 I public static final int simple_expandable_list_item_1 = 17367046; // Field descriptor #8 I public static final int simple_expandable_list_item_2 = 17367047; // Field descriptor #8 I public static final int simple_gallery_item = 17367051; // Field descriptor #8 I public static final int simple_list_item_1 = 17367043; // Field descriptor #8 I public static final int simple_list_item_2 = 17367044; // Field descriptor #8 I public static final int simple_list_item_checked = 17367045; // Field descriptor #8 I public static final int simple_list_item_multiple_choice = 17367056; // Field descriptor #8 I public static final int simple_list_item_single_choice = 17367055; // Field descriptor #8 I public static final int simple_spinner_dropdown_item = 17367049; // Field descriptor #8 I public static final int simple_spinner_item = 17367048; // Field descriptor #8 I public static final int test_list_item = 17367052; // Field descriptor #8 I public static final int two_line_list_item = 17367053; // Method descriptor #50 ()V // Stack: 3, Locals: 1 public R$layout(); 0 aload_0 [this] 1 invokespecial java.lang.Object() [1] 4 new java.lang.RuntimeException [2] 7 dup 8 ldc <String "Stub!"> [3] 10 invokespecial java.lang.RuntimeException(java.lang.String) [4] 13 athrow Line numbers: [pc: 0, line: 899] Local variable table: [pc: 0, pc: 14] local: this index: 0 type: android.R.layout Inner classes: [inner class info: #5 android/R$layout, outer class info: #64 android/R inner name: #55 layout, accessflags: 25 public static final] }

  • counter and displaylist AS3

    - by VideoDnd
    How can I connect my counter to my display list?I've got a counter and a displaylist working, but I need help with everything in between. Try to explain I finished a Snowflake tutorial.

  • .htaccess mod_rewrite issue

    - by Orhan Toy
    Almost in any project I work on, some issues with .htaccess occur. I usually just find the easiest solution and leave it because I don't have any knowledge or understanding for Apache, servers etc. But this time I thought I would ask you guys. This is the files and folders in my (simplified) setup: /modrewrite-test .htaccess /config /inc /lib /public_html .htaccess /cms /navigation index.php edit.php /pages index.php edit.php login.php page.php The "config", "inc" and "lib" folders are meant to be "hidden" from the root of the website. I try to accomplish this by making a .htaccess-file in the root that redirects the user to "public_html". The .htacess-file contains this: RewriteEngine On RewriteRule (.*) public_html/$1 This works perfect. If I type "http://localhost/modrewrite-test/login.php" in my browser, I end up in public_html/login.php which is my intention. So this works fine. The .htaccess-file in "public_html" contains this: RewriteEngine On # Root RewriteRule ^$ page.php [L] # Login RewriteRule ^(admin)|(login)\/?$ login.php [L] # Page (if not a file/directory) RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ page.php?url=$1 [L] The first rewrite just redirects me to public_html/page.php if I try to reach "http://localhost/modrewrite-test/". The next rewrite is just for the convenience of users trying to log in - so if they try to reach "http://localhost/modrewrite-test/admin" or "http://localhost/modrewrite-test/login" they will end up at the login.php-file. The third and last rewrite handles the rest of the requests. If I try to reach "http://localhost/modrewrite-test/bla/bla/bla" it will just redirect me to public_html/page.php (with the 'url' GET-variable set) instead of finding a folder called "la", containing a folder named "bla" and etc. All of these things work perfect but a minor issues occurs when I for instance try to reach "http://localhost/modrewrite-test/cms/navigation" without a slash at the end of the URL. When I try to reach that page the browser is somehow redirected to "http://localhost/modrewrite-test/public_html/cms/navigation/". The correct page is shown but why does it get redirected and add the "public_html" part in the URL? The desired behavior is that the URL stays intact and that the page public_html/cms/navigation/index.php is shown. The files and folders in the (simplified) can be found at http://highbars.com/modrewrite-test.zip

  • Optimizing spacing of mesh containing a given set of points

    - by Feynman
    I tried to summarize the this as best as possible in the title. I am writing an initial value problem solver in the most general way possible. I start with an arbitrary number of initial values at arbitrary locations (inside a boundary.) The first part of my program creates a mesh/grid (I am not sure which is the correct nuance), with N points total, that contains all the initial values. My goal is to optimize the mesh such that the spacing is as uniform as possible. My solver seems to work half decently (it needs some more obscure debugging that is not relevant here.) I am starting with one dimension. I intend to generalize the algorithm to an arbitrary number of dimensions once I get it working consistently. I am writing my code in fortran, but feel free to reply with pseudocode or the language of your choice. Allow me to elaborate with an example: Say I am working on a closed interval [1,10] xmin=1 xmax=10 Say I have 3 initial points: xmin, 5 and xmax num_ivc=3 known(num_ivc)=[xmin,5,xmax] //my arrays start at 1. Assume "known" starts sorted I store my mesh/grid points in an array called coord. Say I want 10 points total in my mesh/grid. N=10 coord(10) Remember, all this is arbitrary--except the variable names of course. The algorithm should set coord to {1,2,3,4,5,6,7,8,9,10} Now for a less trivial example: num_ivc=3 known(num_ivc)=[xmin,5.5,xmax or just num_ivc=1 known(num_ivc)=[5.5] Now, would you have 5 evenly spaced points on the interval [1, 5.5] and 5 evenly spaced points on the interval (5.5, 10]? But there is more space between 1 and 5.5 than between 5.5 and 10. So would you have 6 points on [1, 5.5] followed by 4 on (5.5 to 10]. The key is to minimize the difference in spacing. I have been working on this for 2 days straight and I can assure you it is a lot trickier than it sounds. I have written code that only works if N is large only works if N is small only works if it the known points are close together only works if it the known points are far apart only works if at least one of the known points is near a boundary only works if none of the known points are near a boundary So as you can see, I have coded the gamut of almost-solutions. I cannot figure out a way to get it to perform equally well in all possible scenarios (that is, create the optimum spacing.)

  • Simple database design and LINQ

    - by Anders Svensson
    I have very little experience designing databases, and now I want to create a very simple database that does the same thing I have previously had in xml. Here's the xml: <services> <service type="writing"> <small>125</small> <medium>100</medium> <large>60</large> <xlarge>30</xlarge> </service> <service type="analysis"> <small>56</small> <medium>104</medium> <large>200</large> <xlarge>250</xlarge> </service> </services> Now, I wanted to create the same thing in a SQL database, and started doing this ( hope this formats ok, but you'll get the gist, four columns and two rows): > ServiceType Small Medium Large > > Writing 125 100 60 > > Analysis 56 104 200 This didn't work too well, since I then wanted to use LINQ to select, say, the Large value for Writing (60). But I couldn't use LINQ for this (as far as I know) and use a variable for the size (see parameters in the method below). I could only do that if I had a column like "Size" where Small, Medium, and Large would be the values. But that doesn't feel right either, because then I would get several rows with ServiceType = Writing (3 in this case, one for each size), and the same for Analysis. And if I were to add more servicetypes I would have to do the same. Simply repetitive... Is there any smart way to do this using relationships or something? Using the second design above (although not good), I could use the following LINQ to select a value with parameters sent to the method: protected int GetHourRateDB(string serviceType, Size size) { CalculatorLinqDataContext context = new CalculatorLinqDataContext(); var data = (from calculatorData in context.CalculatorDatas where calculatorData.Service == serviceType && calculatorData.Size == size.ToString() select calculatorData).Single(); return data.Hours; } But if there is another better design, could you please also describe how to do the same selection using LINQ with that design? Please keep in mind that I am a rookie at database design, so please be as explicit and pedagogical as possible :-) Thanks! Anders

  • Problem with return 2 libc method

    - by jth
    Hi, I'am trying to understand the return2libc method. I'am using an ubuntu linux 9.10, 32 bit with ASLR disabled. In theory, it sounds quite easy, overwrite the saved eip with the address of system() (or whatever function you want), then put the address to which system() should return and after that, the parameter for system, the "/bin/bash"-string. But what happens is that my exploit keeps segfaulting the vulnerable program. I assume something with the system()-address went wrong. This is what I did so far: Determined the address of system(): (gdb) print system $1 = {<text variable, no debug info>} 0x167020 <system> (gdb) x/x system 0x167020 <system>: 0x890cec83 I used the subsequent x/x system because those 3 bytes returned by print system looks like an index in some sort of jumptable (PLT?), so I assume 0x890cec83 is the right address which is used to overwrite the saved eip. After that I determined the address of the /bin/bash string in memory, using a small C program which basically consists of this line: printf("Address of string /bin/bash: %p\n", getenv("SHELL")); Then I looked a little bit around in the memory and fount /bin/bash: (gdb) x/s 0xbffff6ca 0xbffff6ca: "/bin/bash" After I gathered this information, I filled the buffer: (gdb) b 9 Breakpoint 1 at 0x8048407: file victim.c, line 9. (gdb) r `perl -e 'print "A"x9 . "\x83\xec\x0c\x89FAKE\xca\f6\ff\bf";'` Breakpoint 1, main (argc=1111638594, argv=0xc360cca) at victim.c:10 10 return 0; (gdb) x/s 0xbffff6ca 0xbffff6ca: "/bin/bash" Stack frame looks like this: (gdb) i f Stack level 0, frame at 0xbffff440: eip = 0x8048407 in main (victim.c:10); saved eip 0x890cec83 source language c. Arglist at 0xbffff438, args: argc=1111638594, argv=0xc360cca Locals at 0xbffff438, Previous frame's sp is 0xbffff440 Saved registers: ebp at 0xbffff438, eip at 0xbffff43c This seems all right to me, saved eip was overwritten with the (hopefully) correct system()-address, return address for system was set to "FAKE" (shouldn't matter) and the address of /bin/bash also seems to be correct. When I'am continuing the execution, victim segfaults on some strange address and certainly not in 0x890cec83: (gdb) cont Continuing. Program received signal SIGSEGV, Segmentation fault. 0x0804840d in main (argc=Cannot access memory at address 0x41414149 ) at victim.c:11 11 } Has anyone an explanation or a hint what happens here and why the execution isn't redirected to 0x890cec83? Thanks in advance, any hint, and be it only vague, would be appreciated. I have no idea why this doesn't work.

  • Calling/selecting variables (float valued) with user input in Python

    - by Jonathan Straus
    I've been working on a computational physics project (plotting related rates of chemical reactants with respect to eachother to show oscillatory behavior) with a fair amount of success. However, one of my simulations involves more than two active oscillating agents (five, in fact) which would obviously be unsuitable for any single visual plot... My scheme was hence to have the user select which two reactants they wanted plotted on the x-axis and y-axis respectively. I tried (foolishly) to convert string input values into the respective variable names, but I guess I need a radically different approach if any exist? If it helps clarify any, here is part of my code: def coupledBrusselator(A, B, t_trial,display_x,display_y): t = 0 t_step = .01 X = 0 Y = 0 E = 0 U = 0 V = 0 dX = (A) - (B+1)*(X) + (X**2)*(Y) dY = (B)*(X) - (X**2)*(Y) dE = -(E)*(U) - (X) dU = (U**2)*(V) -(E+1)*(U) - (B)*(X) dV = (E)*(U) - (U**2)*(V) array_t = [0] array_X = [0] array_Y = [0] array_U = [0] array_V = [0] while t <= t_trial: X_1 = X + (dX)*(t_step/2) Y_1 = Y + (dY)*(t_step/2) E_1 = E + (dE)*(t_step/2) U_1 = U + (dU)*(t_step/2) V_1 = V + (dV)*(t_step/2) dX_1 = (A) - (B+1)*(X_1) + (X_1**2)*(Y_1) dY_1 = (B)*(X_1) - (X_1**2)*(Y_1) dE_1 = -(E_1)*(U_1) - (X_1) dU_1 = (U_1**2)*(V_1) -(E_1+1)*(U_1) - (B)*(X_1) dV_1 = (E_1)*(U_1) - (U_1**2)*(V_1) X_2 = X + (dX_1)*(t_step/2) Y_2 = Y + (dY_1)*(t_step/2) E_2 = E + (dE_1)*(t_step/2) U_2 = U + (dU_1)*(t_step/2) V_2 = V + (dV_1)*(t_step/2) dX_2 = (A) - (B+1)*(X_2) + (X_2**2)*(Y_2) dY_2 = (B)*(X_2) - (X_2**2)*(Y_2) dE_2 = -(E_2)*(U_2) - (X_2) dU_2 = (U_2**2)*(V_2) -(E_2+1)*(U_2) - (B)*(X_2) dV_2 = (E_2)*(U_2) - (U_2**2)*(V_2) X_3 = X + (dX_2)*(t_step) Y_3 = Y + (dY_2)*(t_step) E_3 = E + (dE_2)*(t_step) U_3 = U + (dU_2)*(t_step) V_3 = V + (dV_2)*(t_step) dX_3 = (A) - (B+1)*(X_3) + (X_3**2)*(Y_3) dY_3 = (B)*(X_3) - (X_3**2)*(Y_3) dE_3 = -(E_3)*(U_3) - (X_3) dU_3 = (U_3**2)*(V_3) -(E_3+1)*(U_3) - (B)*(X_3) dV_3 = (E_3)*(U_3) - (U_3**2)*(V_3) X = X + ((dX + 2*dX_1 + 2*dX_2 + dX_3)/6) * t_step Y = Y + ((dX + 2*dY_1 + 2*dY_2 + dY_3)/6) * t_step E = E + ((dE + 2*dE_1 + 2*dE_2 + dE_3)/6) * t_step U = U + ((dU + 2*dU_1 + 2*dY_2 + dE_3)/6) * t_step V = V + ((dV + 2*dV_1 + 2*dV_2 + dE_3)/6) * t_step dX = (A) - (B+1)*(X) + (X**2)*(Y) dY = (B)*(X) - (X**2)*(Y) t_step = .01 / (1 + dX**2 + dY**2) ** .5 t = t + t_step array_X.append(X) array_Y.append(Y) array_E.append(E) array_U.append(U) array_V.append(V) array_t.append(t) where previously display_x = raw_input("Choose catalyst you wish to analyze in the phase/field diagrams (X, Y, E, U, or V) ") display_y = raw_input("Choose one other catalyst from list you wish to include in phase/field diagrams ") coupledBrusselator(A, B, t_trial, display_x, display_y) Thanks!

  • Need to optimize this PHP script for "recent posts". Fatal error when post count is high...

    - by Scott B
    The code below is resulting in an error on a site in which there are ~ 1500 posts. It performs fine when post count is nominal, however, this heavy load is exposing the weakness of the code and I'd like to optimize it. Interestingly, when I disable this menu and instead use the "Recent Posts" widget, the posts are drawn fine. So I'd probably do good to borrow from that code if I knew where to find it, or better yet, If I could call the widget directly in my theme, passing it a post count variable. Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 16384 bytes) in /home1/est/public_html/mysite/wp-includes/post.php on line 3462 The code is below. Its purpose is to list "recent posts". global $post; $cat=get_cat_ID('myMenu'); $cathidePost=get_cat_ID('hidePost'); $myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$cathidePost",'showposts' => $count-of-posts)); $myrecentposts2 = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$cathidePost",'showposts' => -1)); $myrecentpostscount = count($myrecentposts2); if ($myrecentpostscount > 0) { ?> <div class="recentPosts"><h4><?php if ($myHeading !=="") { echo $myHeading; } else { echo "Recent Posts";} ?></h4><ul> <?php $current_page_recent = get_post( $current_page ); foreach($myrecentposts as $idxrecent=>$post) { if($post->ID == $current_page_recent->ID) { $home_menu_recent = ' class="current_page_item'; } else { $home_menu_recent = ' class="page_item'; } $myclassrecent = ($idxrecent == count($myrecentposts) - 1 ? $home_menu_recent.' last"' : $home_menu_recent.'"'); ?> <li<?php echo $myclassrecent ?>><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li> <?php } ; if (($myrecentpostscount > $count-of-posts) && $count-of-posts > -1){ ?><li><a href="<?php bloginfo('url'); ?>/recent">View All Posts</a></li><?php } ?></ul></div>

  • How to make this sub-sub-query work?

    - by Josh Weissbock
    I am trying to do this in one query. I asked a similar question a few days ago but my personal requirements have changed. I have a game type website where users can attend "classes". There are three tables in my DB. I am using MySQL. I have four tables: hl_classes (int id, int professor, varchar class, text description) hl_classes_lessons (int id, int class_id, varchar lessonTitle, varchar lexiconLink, text lessonData) hl_classes_answers (int id, int lesson_id, int student, text submit_answer, int percent) hl_classes stores all of the classes on the website. The lessons are the individual lessons for each class. A class can have infinite lessons. Each lesson is available in a specific term. hl_classes_terms stores a list of all the terms and the current term has the field active = '1'. When a user submits their answers to a lesson it is stored in hl_classes_answers. A user can only answer each lesson once. Lessons have to be answered sequentially. All users attend all "classes". What I am trying to do is grab the next lesson for each user to do in each class. When the users start they are in term 1. When they complete all 10 lessons in each class they move on to term 2. When they finish lesson 20 for each class they move on to term 3. Let's say we know the term the user is in by the PHP variable $term. So this is my query I am currently trying to massage out but it doesn't work. Specifically because of the hC.id is unknown in the WHERE clause SELECT hC.id, hC.class, (SELECT MIN(output.id) as nextLessonID FROM ( SELECT id, class_id FROM hl_classes_lessons hL WHERE hL.class_id = hC.id ORDER BY hL.id LIMIT $term,10 ) as output WHERE output.id NOT IN (SELECT lesson_id FROM hl_classes_answers WHERE student = $USER_ID)) as nextLessonID FROM hl_classes hC My logic behind this query is first to For each class; select all of the lessons in the term the current user is in. From this sort out the lessons the user has already done and grab the MINIMUM id of the lessons yet to be done. This will be the lesson the user has to do. I hope I have made my question clear enough.

    Hi, could you please help me find the reason of the mystery I've found? In the below code, I create a DataTable and filter it. When I use filter1, everything works as expected. When I use filter2, everything works as expected only if the SubsectionAmount variable is less than 10. As soon as I set SubsectionAmount=10, the dr2 array returns Nothing. I can't find what is wrong. Here is the code: Imports System.Data Partial Class FilterTest Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Call FilterTable() End Sub Sub FilterTable() Dim dtSubsections As New DataTable Dim SectionID As Integer, SubsectionID As Integer Dim SubsectionAmount As Integer Dim filter1 As String, filter2 As String Dim rowID As Integer Dim dr1() As DataRow, dr2() As DataRow With dtSubsections .Columns.Add("Section") .Columns.Add("Subsection") .Columns.Add("FieldString") SectionID = 1 SubsectionAmount = 10 '9 For SubsectionID = 1 To SubsectionAmount .Rows.Add(SectionID, SubsectionID, "abcd" & CStr(SubsectionID)) Next SubsectionID For rowID = 0 To .Rows.Count - 1 Response.Write(.Rows(rowID).Item(0).ToString & " " _ & .Rows(rowID).Item(1).ToString & " " _ & .Rows(rowID).Item(2).ToString & "<BR>") Next SubsectionID = 1 filter1 = "Section=" & SectionID & " AND " & "Subsection=" & SubsectionID filter2 = "Section=" & SectionID & " AND " & "Subsection=" & SubsectionID + 1 dr1 = .Select(filter1) dr2 = .Select(filter2) Response.Write(dr1.Length & "<BR>") Response.Write(dr2.Length & "<BR>") If dr1.Length > 0 Then Response.Write(dr1(0).Item("FieldString").ToString & "<BR>") End If If dr2.Length > 0 Then Response.Write(dr2(0).Item("FieldString").ToString & "<BR>") End If End With End Sub End Class

  • Nservicebus serization issue of derived types

    - by Tiju John
    Hi Guys, for the context setting, I am exchanging messages between my nServiceBus client and nSerivceBus server. its is the namespace xyz.Messages and and a class, Message : IMessage I have more messages that are in the other dlls, like xyz.Messages.Domain1, xyz.Messages.Domain2, xyz.Messages.Domain3. and messages that derive form that base message, Message. I have the endpoints defined as like : at client <UnicastBusConfig> <MessageEndpointMappings> <add Messages="xyz.Messages" Endpoint="xyzServerQueue" /> <add Messages="xyz.Messages.Domain1" Endpoint="xyzServerQueue" /> <add Messages="xyz.Messages.Domain2" Endpoint="xyzServerQueue" /> </MessageEndpointMappings> </UnicastBusConfig> at Server <UnicastBusConfig> <MessageEndpointMappings> <add Messages="xyz.Messages" Endpoint="xyzClientQueue" /> <add Messages="xyz.Messages.Domain1" Endpoint="xyzClientQueue" /> <add Messages="xyz.Messages.Domain2" Endpoint="xyzClientQueue" /> </MessageEndpointMappings> </UnicastBusConfig> and the bus initialized as IBus serviceBus = Configure.With() .SpringBuilder() .XmlSerializer() .MsmqTransport() .UnicastBus() .LoadMessageHandlers() .CreateBus() .Start(); now when i try sending instance of Message type or any type derived types of Message, it successfully sends the message over and at the server, i get the proper type. eg. Message message= new Message(); Bus.Send(message); // works fine, transfers Message type message = new MessageDerived1(); Bus.Send(message); // works fine, transfers MessageDerived1 type message = new MessageDerived2(); Bus.Send(message); // works fine, transfers MessageDerived2 type My problem arises when any type, say MessageDerived1, contains a member variable of type Message, and when i assign it to a derived type, the type is not properly transferred over the wire. It transfers only as Message type, not the derived type. public class MessageDerived2 : Message { public Message message; } MessageDerived2 messageDerived2= new MessageDerived2(); messageDerived2.message = new MessageDerived1(); message = messageDerived2; Bus.Send(message); // incorrect behaviour, transfers MessageDerived2 correctly, but looses type of MessageDerived2.Message (it deserializes as Message type, instead of MessageDerived1) any help is strongly appreciated. Thanks TJ

  • casting, converting, and input from textbox controls

    - by Matt
    Working on some .aspx.cs code and decided I would forget how to turn a textbox value into a useable integer or decimal. Be warned I'm pretty new to .asp. Wish I could say the same for c sharp. So the value going into my textbox (strawberryp_textbox) is "1" which I presume I can access with the .text property. Which I then parse into a int. The Error reads Format Exception was unhandled by user code. My other question is can I do operations on a session variable? protected void submit_order_button_Click(object sender, EventArgs e) { int strawberryp; int strawberrys; decimal money1 = decimal.Parse(moneybox1.Text); decimal money2 = decimal.Parse(moneybox2.Text); decimal money3 = decimal.Parse(moneybox3.Text); decimal money4 = decimal.Parse(moneybox4.Text); decimal money5 = decimal.Parse(moneybox5.Text); strawberryp = int.Parse(strawberryp_Textbox.Text); //THE PROBLEM RIGHT HERE! strawberrys = int.Parse(strawberrys_Textbox.Text); // Needs fixed int strawberryc = int.Parse(strawberryc_Textbox.Text); //fix int berryp = int.Parse(berryp_Textbox.Text); //fix int raspberryp = int.Parse(raspberryp_Textbox.Text); /fix decimal subtotal = (money1 * strawberryp) + (money2 * strawberrys) + (money3 * strawberryc) + (money4 * berryp) + (money5 * raspberryp); //check to see if you can multiply decimal and int to get a deciaml!! Session["passmysubtotal"] = subtotal; //TextBox2.Text; (strawberryp_Textbox.Text);//TextBox4.Text; add_my_order_button.Enabled = true; add_my_order_button.Visible = true; submit_order_button.Enabled = false; submit_order_button.Visible = false; strawberryp_Textbox.ReadOnly = false; strawberrys_Textbox.ReadOnly = false; strawberryc_Textbox.ReadOnly = false; berryp_Textbox.ReadOnly = false; raspberryp_Textbox.ReadOnly = false; Response.Redirect("reciept.aspx"); } Thanks for the help
