  • Encrypting a non-linux partition with LUKS.

    - by linuxn00b
    I have a non-Linux partition I want to encrypt with LUKS. The goal is to be able to store it by itself on a device without Linux and access it from the device when needed with an Ubuntu Live CD. I know LUKS can't encrypt partitions in place, so I created another, unformatted partition of the EXACT same size (using GParted's "Round to MiB" option) and ran this command: sudo cryptsetup luksFormat /dev/xxx Where xxx is the partition's device name. Then I typed in my new passphrase and confirmed it. Oddly, the command exited immediately after, so I guess it doesn't encrypt the entire partition right away? Anyway, then I ran this command: sudo cryptsetup luksOpen /dev/xxx xxx Then I tried copying the contents of the existing partition (call it yyy) to the encrypted one like this: sudo dd if=/dev/yyy of=/dev/mapper/xxx bs=1MB and it ran for a while, but exited with this: dd: writing `/dev/mapper/xxx': No space left on device just before writing the last MB. I take this to mean the contents of yyy was truncated when it was copied to xxx, because I have dd'd it before, and whenever I have dd'd to a partition of the exact same size, I never get that error. (and fdisk reports they are the same size in blocks). After a little Googling I discovered all luksFormat'ted partitions have a custom header followed by the encrypted contents. So it appears I need to create a partition exactly the size of the old one + however many bytes a LUKS header is. What size should the destination partition be, no. 1, and no. 2, am I even on the right track here? UPDATE I found this in the LUKS FAQ: I think this is overly complicated. Is there an alternative? Yes, you can use plain dm-crypt. It does not allow multiple passphrases, but on the plus side, it has zero on disk description and if you overwrite some part of a plain dm-crypt partition, exactly the overwritten parts are lost (rounded up to sector borders). So perhaps I shouldn't be using LUKS at all?

  • Building Interactive User Interfaces with Microsoft ASP.NET AJAX: Refreshing An UpdatePanel With Jav

    The ASP.NET AJAX UpdatePanel provides a quick and easy way to implement a snappier, AJAX-based user interface in an ASP.NET WebForm. In a nutshell, UpdatePanels allow page developers to refresh selected parts of the page (instead of refreshing the entire page). Typically, an UpdatePanel contains user interface elements that would normally trigger a full page postback - controls like Buttons or DropDownLists that have their AutoPostBack property set to True. Such controls, when placed inside an UpdatePanel, cause a partial page postback to occur. On a partial page postback only the contents of the UpdatePanel are refreshed, avoiding the "flash" of having the entire page reloaded. (For a more in-depth look at the UpdatePanel control, refer back to the Using the UpdatePanel installment in this article series.) Triggering a partial page postback refreshes the contents within an UpdatePanel, but what if you want to refresh an UpdatePanel's contents via JavaScript? Ideally, the UpdatePanel would have a client-side function named something like Refresh that could be called from script to perform a partial page postback and refresh the UpdatePanel. Unfortunately, no such function exists. Instead, you have to write script that triggers a partial page postback for the UpdatePanel you want to refresh. This article looks at how to accomplish this using just a single line of markup/script and includes a working demo you can download and try out for yourself. Read on to learn more! Read More >

  • Deletes not cascading for self-referencing entities

    - by jwaddell
    I have the following (simplified) Hibernate entities: @Entity @Table(name = "package") public class Package { protected Content content; @OneToOne(cascade = {javax.persistence.CascadeType.ALL}) @JoinColumn(name = "content_id") @Fetch(value = FetchMode.JOIN) public Content getContent() { return content; } public void setContent(Content content) { this.content = content; } } @Entity @Table(name = "content") public class Content { private Set<Content> subContents = new HashSet<Content>(); private ArchivalInformationPackage parentPackage; @OneToMany(fetch = FetchType.EAGER) @JoinTable(name = "subcontents", joinColumns = {@JoinColumn(name = "content_id")}, inverseJoinColumns = {@JoinColumn(name = "elt")}) @Cascade(value = {org.hibernate.annotations.CascadeType.DELETE, org.hibernate.annotations.CascadeType.REPLICATE}) @Fetch(value = FetchMode.SUBSELECT) public Set<Content> getSubContents() { return subContents; } public void setSubContents(Set<Content> subContents) { this.subContents = subContents; } @ManyToOne(cascade = {CascadeType.ALL}) @JoinColumn(name = "parent_package_id") public Package getParentPackage() { return parentPackage; } public void setParentPackage(Package parentPackage) { this.parentPackage = parentPackage; } } So there is one Package, which has one "top" Content. The top Content links back to the Package, with cascade set to ALL. The top Content may have many "sub" Contents, and each sub-Content may have many sub-Contents of its own. Each sub-Content has a parent Package, which may or may not be the same Package as the top Content (ie a many-to-one relationship for Content to Package). The relationships are required to be ManyToOne (Package to Content) and ManyToMany (Content to sub-Contents) but for the case I am currently testing each sub-Content only relates to one Package or Content. The problem is that when I delete a Package and flush the session, I get a Hibernate error stating that I'm violating a foreign key constraint on table subcontents, with a particular content_id still referenced from table subcontents. I've tried specifically (recursively) deleting the Contents before deleting the Package but I get the same error. Is there a reason why this entity tree is not being deleted properly? EDIT: After reading answers/comments I realised that a Content cannot have multiple Packages, and a sub-Content cannot have multiple parent-Contents, so I have modified the annotations from ManyToOne and ManyToMany to OneToOne and OneToMany. Unfortunately that did not fix the problem. I have also added the bi-directional link from Content back to the parent Package which I left out of the simplified code.

  • How can I ensure my programmatic uploads are done in the correct order?

    - by ccomet
    In our application, we store two copies of a file - an approved one and an unapproved one. Both track their versions separately. When the unapproved is then approved, all of its versions are added as new versions to the approved file. To do this properly, my code has to upload each version separately into the approved folder, and update the item each time with that version's information. For some reason, though, this doesn't always work properly. In my latest scenario, the latest version was uploaded first, and then all of the remaining versions were uploaded afterwards. However, my code explicitly is supposed to upload the other versions first, that's the order I wrote it in. Why is this happening? And if it is possible, how do I ensure that the versions are uploaded in the correct order? Clarification - It's not a problem with the enumeration - I'm getting the previous versions in the correct order. What is happening is that the final version, which is written after the loop, is being uploaded before the loop. Which really doesn't make any sense to me. Here's a condensed version of the relevant code. //These three are initialized earlier in the code. SPList list; //The document library SPListItem item; //The list item in the Unapproved folder int AID; //The item id of the corresponding item in the Approved folder. byte[] contents; //Not initialized. /* These uploads are happening second when they should happen first. */ if (item.File.Versions.Count > 0) { //This loop is actually a separate method call if that matters. //For simplicity I expanded it here. foreach (SPFileVersion fVer in item.File.Versions) { if (!fVer.IsCurrentVersion) { contents = fVer.OpenBinary(); SPFile fSub = aFolder.Files.Add(fVer.File.Name, contents, u1, fVer.CreatedBy, dt1, fVer.Created); SPListItem subItem = list.GetItemById(AID); //This method updates the newly uploaded version with the field data of that version. UpdateFields(item.Versions.GetVersionFromLabel(fVer.VersionLabel), subItem); } } } /* This upload happens first when it should happen last. */ //Does the same as earlier loop, but for the final version. contents = item.File.OpenBinary(); SPFile f = aFolder.Files.Add(item.File.Name, contents, u1, u2, dt1, dt2); SPListItem finalItem = list.GetItemById(AID); UpdateFields(item.Versions[0], finalItem); item.Delete();

  • How to use Wordpress' http.php in external projects?

  • appstats broken filename in callstack

    - by Ray Yun
    When I visit appstats page and expand callstack, the file path has <path[N]> prefix. So click the file link then emit no such file or directory error. Stack: /google/appengine/datastore/datastore_rpc.py:951 make_rpc_call() /google/appengine/datastore/datastore_query.py:993 _make_query_result_rpc_call() /google/appengine/datastore/datastore_query.py:714 run_async() /google/appengine/datastore/datastore_query.py:685 run() /google/appengine/api/datastore.py:1281 GetBatcher() /google/appengine/api/datastore.py:1351 Get() /google/appengine/ext/db/init.py:1831 fetch() /google/appengine/ext/db/init.py:1778 get() /apps/fbapp/fbutil.py:232 oauth_load_fb_user() /apps/fbapp/fbutil.py:84 require_account() the error message for appengine source: [Errno 2] No such file or directory: u'/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/ipaddr/google/appengine/datastore/datastore_rpc.py' the error message for my source: IOError [Errno 2] No such file or directory: u'/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/antlr3/apps/fbapp/fbutil.py' I guess this was path problem and found some official comment from google. If your request handlers modify sys.path, you must make the same modifications to sys.path in appengine_config.py so the Appstats web interface can see all files. Actually I'm using appengine_django and two path was inserted to sys.path. I did it same again at appengine_django.py but also failed. Maybe some custom setting with appengine_config.py can solve this problem but doesn't figure out how to fix it. What can I do?

  • Dynamically created "CheckBoxList" in placeholder controls throwing null reference exception error d

    - by newName
    I have a web form that will dynamically create a number of checkboxlist filled with data based on the number of row in database. Then this is added to a placeholder to be displayed. theres a button when clicked, will add the selected check boxes value into database but right now when the button is clicked and after the postback, the page will show the error "System.NullReferenceException". the following code is written in Page_Load in (!Page.IsNotPostBack) and in a loop that will dynamically create a number of checkboxlist: CheckBoxLis chkContent = new CheckBoxList(); chkContent.ID = chkIDString; //chkIDString is an incremental int based on the row count chkContent.RepeatDirection = RepeatDirection.Horizontal; foreach (List<t> contentList in List<t>) //data retrieved as List<t> using LINQ { ListItem contents = new ListItem(); contents.Text = contentList.Title; contents.Value = contentList.contentID.ToString(); chkContent.Items.Add(contents); } plcSchool.Controls.Add(chkContent); //plcSchool is my placeholder plcSchool.Controls.Add(new LiteralControl("<br>")); protected void btnAdd_Click(object sender, EventArgs e) { CheckBoxList cbl = Page.FindControl("chkContent4") as CheckBoxList; Response.Write(cbl.SelectedValue.ToString()); // now im just testing to get the value from one of the checkboxlist } Anyone able to help, as it seems the controls are not recreated after the postback, therefore it can't find the control and throwing the null reference exception.

  • IE8 (compatibility mode) won't load my Ajax content

    - by Jens Roland
    Hi all - I am working on a jQuery script on http://www.qxl.dk/ and I can't seem to get IE7 (or more accurately, IE8 in IE7 compatibility mode) to load my content. The sidebar box on the right named "QXL Aktuelt" loads its HTML content from an external file using Ajax load(), then triggers a custom jQuery event ("aktuelt_loaded") that starts a carousel script (like a scrolling newsticker). Several other content sections on the same page are loaded through Ajax and they work just fine, so I'm wondering what's going wrong. Everything works as expected in Firefox 3.6 and IE8, but not in IE8's compatibility mode. The script that loads the Ajax content is (inline on the page): <div id="qxlaktueltHolder"></div> <script type="text/javascript"> $("#qxlaktueltHolder").load("/contents/dk/modul/qxlaktuelt/qxlaktuelt.htm", function() { $("#qxlaktueltHolder").trigger("qxlaktuelt_loaded", []); }); </script> <script type='text/javascript' src='http://www.qxl.dk/contents/dk/js/jcarousellite_1.0.1.min.js'></script> <script type='text/javascript' src='http://www.qxl.dk/contents/dk/js/qxlaktuelt_liveload.js'></script> The external script that responds to the event is in the following file: http://www.qxl.dk/contents/dk/js/qxlaktuelt_liveload.js All ideas are very welcome.

  • jQuery Colorbox Iframe and Selector

    - by Joker
    I have this: $("a.money").colorbox({href:$("a.money").attr("href")+" div#content"}); Which opens an overlay but only of the content within the #content selector. If I add iframe:true, this will no longer work. Is there a way to get it to work with an iframe? Edit: The closest I could get it to work was by doing this: $("a.money").colorbox({iframe:true, width:700, height:425, onComplete: function() { alert('test'); $test = $("#cboxLoadedContent iframe").contents().find("#content").html(); $("#cboxLoadedContent iframe").contents().find("#container").html($test); } }); Although without the alert it doesn't appear to work, I looked into that and I think I need to use .live(), which led me to trying this: $('a.money').live('click', function() { url = this.href; // this is the url of the element event is triggered from $.fn.colorbox({href: url, iframe:true,width:700, height:425, onComplete: function() { $test = $("#cboxLoadedContent iframe").contents().find("#content").html(); $("#cboxLoadedContent iframe").contents().find("#container").html($test); } }); return false; }); Didn't work, I still needed to add an alert to make it work. In case you might be wondering what I'm trying to do. The webpage is loaded in the iframe, with all the elements in the #container, so that includes #header, #sidebars, but I only want to show the #content inside the iframe. However, this led me to another problem I realized. Assuming I got this to work without the alert, it will only work for that initial page. For example, if I loaded up a form in the iframe, after submitting the form, I would once again see the whole layout instead of just the #content portion. Is it possible to continue only showing the #content portion of the page upon further navigation?

  • Exporting to CSV from MySQL via PHP in FireFox

    - by typoknig
    Hi all, I am pulling some info from a database with the following code: <input type="button" value="Export to Excel" onClick="window.navigate('breakfast_service.php?action=export')"> Here is the code for that action. <?php if ($_GET['action'] == 'export') { // Get the registration data $user = 'root'; $pass = 'billiards'; $server = 'localhost'; $link = mysql_connect($server, $user, $pass); if (!$link) { die('Could not connect to database!' . mysql_error()); } mysql_select_db('breakfast', $link); $query = "SELECT * FROM registration"; $result = mysql_query($query); mysql_close($link); // format into CSV $contents = "id, school_id, first_name, last_name, email, attending, created_on\n"; $num = mysql_num_rows($result); for ($i = 0; $i < $num; $i++) { $row = mysql_fetch_array($result); $id = $row['id']; $school_id = $row['school_id']; $fname = $row['first_name']; $lname = $row['last_name']; $email = $row['email']; $attending = ($row['attending'] == 0) ? 'No' : 'Yes'; $date = $row['created_on']; $contents = $contents .

Why?

  • latex padding / margin hell

    - by darren
    hi everyone I have been wrestling with a latex table for far too long. I need a table that has has centered headers, and body cells that contain text that may wrap around. Because of the wrap-around requirement, i'm using p{xxx} instead of l for specifying cell widths. The problem this causes is that cell contents are not left justified, so the look like spaced-out junk. To fix this problem I'm using \flushleft for each cell. This does left justify contents, but puts in a ton of white space above and below the contents of the cell. Is there a way to stop \flushleft (or \center for that matter) to stop adding copious amounts of verical whitespace? thanks \begin{landscape} \centering % using p{xxx} here to wrap long text instead of overflowing it \begin{longtable}{ | p{4cm} || p{3cm} | p{3cm} | p{3cm} | p{3cm} | p{3cm} |} \hline & % these are table headings. the \center is causing a ton of whitespace as well \begin{center} \textbf{HTC HD2} \end{center} & \begin{center} \textbf{Motorola Milestone} \end{center} & \begin{center} \textbf{Nokia N900} \end{center} & \begin{center} \textbf{RIM Blackberry Bold 9700} \end{center} & \begin{center} \textbf{Apple iPhone 3GS} \end{center} \\ \hline \hline % using flushleft here to left-justify, but again it is causing a ton of white space above and below cell contents. \begin{flushleft}OS / Platform \end{flushleft}& \begin{flushleft}Windows Mobile 6.5 \end{flushleft}& \begin{flushleft}Google Android 2.1 \end{flushleft}& \begin{flushleft}Maemo \end{flushleft}& \begin{flushleft}Blackberry OS 5.0 \end{flushleft}& \begin{flushleft}iPhone OS 3.1 \end{flushleft} \\ \hline

  • Sphinx - Python modules, classes and functions documentation

    - by user343934
    Hi everyone, I am trying to document my small project through sphinx which im recently trying to get familiar with. I read some tutorials and sphinx documentation but couldn't make it. Setup and configurations are ok! just have problems in using sphinx in a technical way. My table of content should look like this --- Overview .....Contents ----Configuration ....Contents ---- System Requirements .....Contents ---- How to use .....Contents ---- Modules ..... Index ......Display ----Help ......Content Moreover my focus is on Modules with docstrings. Details of Modules are Directory:- c:/wamp/www/project/ ----- Index.py >> Class HtmlTemplate: .... def header(): .... def body(): .... def form(): .... def header(): .... __init_main: ##inline function ----- display.py >> Class MainDisplay: .... def execute(): .... def display(): .... def tree(): .... __init_main: ##inline function My Documentation Directory:- c:/users/abc/Desktop/Documentation/doc/ --- _build --- _static --- _templates --- conf.py --- index.rst I have added Modules directory to the system environment and edited index.rst with following codes just to test Table of content. But i couldn't extract docstring directly Index.rst T-Alignment Documentation The documentation covers general overview of the application covering functionalities and requirements in details. To know how to use application its better to go through the documentation. .. _overview: Overview .. _System Requirement: System Requirement Seq-alignment tools can be used in varied systems base on whether all intermediary applications are available or not like in Windows, Mac, Linux and UNIX.

  • SWT: scrollable area within a tab

    - by DaveJohnston
    I am trying to add a scrollable area to my tabbed window. So far I have a CTabFolder in a shell. I have added 5 CTabItems to it and everything works as expected. On one of my CTabItems the contents are too big to fit on the screen so I would like to be able to scroll. The contents is a collection of Groups each containing various widgets. So the CTabFolder is created as follows: CTabFolder tabs = new CTabFolder(shell, SWT.BORDER); tabs.setSimple(false); tabs.setUnselectedImageVisible(false); tabs.setUnselectedCloseVisible(false); tabs.setMinimizeVisible(false); tabs.setMaximizeVisible(false); FormData tabsLayoutData = new FormData(); tabsLayoutData.top = new FormAttachment(0, 5); tabsLayoutData.left = new FormAttachment(0, 5); tabsLayoutData.bottom = new FormAttachment(92, 0); tabsLayoutData.right = new FormAttachment(100, -5); tabs.setLayoutData(tabsLayoutData); Then the CTabItem: CTabItem tab = new CTabItem(tabs, SWT.NONE); tab.setText("Role"); Then the contents: Composite tabArea = new Composite(tabs, SWT.V_SCROLL); tabArea.setLayout(new FormLayout()); tab.setControl(tabArea); So the groups contained within the tab are created with tabArea as the parent and everything appears as you would expect. The problem is though that the vertical scroll bar is always present but doesn't seem to do anything. The contents are chopped off at the bottom of the tabArea composite. Is there anything else I need to do to get the scrolling to work properly?

  • How can I test a CRON job with PHP?

    - by alex
    This is the first time I've ever used a CRON. I'm using it to parse external data that is automatically FTP'd to a subdirectory on our site. I have created a controller and model which handles the data. I can access the URL fine in my browser and it works (however I will be restricting this soon). My problem is, how can I test if it's working? I've added this to my controller for a quick and dirty log $file = 'test.txt'; $contents = ''; if (file_exists($file)) { $contents = file_get_contents($file); } $contents .= date('m-d-Y') . ' --- ' . PHP_SAPI . "\n\n"; file_put_contents($file, $contents); But so far only got requests logged from myself from the browser, despite having my CRON running ever minute. 03-18-2010 --- cgi-fcgi 03-18-2010 --- cgi-fcgi I've set it up using cPanel with the command index.php properties/update/ the 2nd portion is what I use to access the page in my browser. So how can I test this is working properly, and have I stuffed anything up? Note: I'm using Kohana 3. Many thanks

  • Facebook Open Graph - post to all approved users feeds.

    - by simnom
    Hi, I'm struggling to get to grips with posting a feed item to all the members of an approved application. Within the application settings for the user it is stating that the application has permission to post to the wall but I can only achieve this if that user is currently logged in to facebook. Obviously I would like this to function so that any items I uploaded are posted to all the members of the application at any one time. I am using the Facebook PHP SDK from http://github.com/facebook/php-sdk/ and currrently my code is as follows: require 'src/facebook.php'; //Generates access token for this transaction $accessToken = file_get_contents("https://graph.facebook.com/oauth/access_token?type=client_cred&client_id=MyAppId&client_secret=MySecret"); //Gets the full user details as an object $contents = json_decode(file_get_contents("https://graph.facebook.com/SomeUserId?scope=publish_stream&" . $accessToken)); print_r($contents); if ($facebook->api('/' . $contents->id . '/feed', 'POST', array( 'title' => 'New and Improved, etc - 12/03/2010', 'link' => 'http://www.ib3.co.uk/news/2010/03/12/new-and-improved--etc', 'picture' => 'http://www.ib3.co.uk/userfiles/image/etc-booking.jpg', 'scope' => 'publish_stream' ) )==TRUE) { echo "message posted"; } else { echo "message failed"; } The output from $contents shows the expected user details but nothing relating to the permissions for my application. Am I missing a trick here? Then using the $facebook-api() function I am receiving a #200 - Permissions error. The application does not have permission to perform this action. This is driving me a little potty as I suspect I'm missing something straightforward with the authorisation but what? Many thanks in advance for an assistance offered.

  • Hibernate: deletes not cascading for self-referencing entities

    - by jwaddell
    I have the following (simplified) Hibernate entities: @Entity @Table(name = "package") public abstract class Package { protected Content content; @ManyToOne(cascade = {javax.persistence.CascadeType.ALL}) @JoinColumn(name = "content_id") @Fetch(value = FetchMode.JOIN) public Content getContent() { return content; } public void setContent(Content content) { this.content = content; } } @Entity @Table(name = "content") public class Content { private Set<Content> subContents = new HashSet<Content>(); @ManyToMany(fetch = FetchType.EAGER) @JoinTable(name = "subcontents", joinColumns = {@JoinColumn(name = "content_id")}, inverseJoinColumns = {@JoinColumn(name = "elt")}) @Cascade(value = {org.hibernate.annotations.CascadeType.DELETE, org.hibernate.annotations.CascadeType.REPLICATE}) @Fetch(value = FetchMode.SUBSELECT) public Set<Content> getSubContents() { return subContents; } public void setSubContents(Set<Content> subContents) { this.subContents = subContents; } } So a Package has a Content, and a Content is self-referencing in that it has many sub-Contents (which may contain sub-Contents of their own etc). The relationships are required to be ManyToOne (Package to Content) and ManyToMany (Content to sub-Contents) but for the case I am currently testing each sub-Content only relates to one Package or Content. The problem is that when I delete a Package and flush the session, I get a Hibernate error stating that I'm violating a foreign key constraint on table subcontents, with a particular content_id still referenced from table subcontents. I've tried specifically (recursively) deleting the Contents before deleting the Package but I get the same error. Is there a reason why this entity tree is not being deleted properly?

  • PHP - print content from file after manipulation

    - by ludicco
    Hello there, I'm struggling trying to read a php file inside a php and do some manipulation..after that have the content as a string, but when I try to output that with echo or print all the php tags are literally included on the file. so here is my code: function compilePage($page,$path){ $contents = array(); $menu = getMenuFor($page); $file = file_get_contents($path); array_push($contents,$menu); array_push($contents,$file); return implode("\n",$contents); } and this will return a string like <div id="content> <h2>Here is my title</h2> <p><? echo "my body text"; ?></p> </div> but this will print exactly the content above not compiling the php on it. So, how can I render this "compilePage" making sure it returns a compiled php result and not just a plain text? Thanks in advance

  • Regex Replacing only whole matches

    - by Leen Balsters
    I am trying to replace a bunch of strings in files. The strings are stored in a datatable along with the new string value. string contents = File.ReadAllText(file); foreach (DataRow dr in FolderRenames.Rows) { contents = Regex.Replace(contents, dr["find"].ToString(), dr["replace"].ToString()); File.SetAttributes(file, FileAttributes.Normal); File.WriteAllText(file, contents); } The strings look like this _-uUa, -_uU, _-Ha etc. The problem that I am having is when for example this string "_uU" will also overwrite "_-uUa" so the replacement would look like "newvaluea" Is there a way to tell regex to look at the next character after the found string and make sure it is not an alphanumeric character? I hope it is clear what I am trying to do here. Here is some sample data: private function _-0iX(arg1:flash.events.Event):void { if (arg1.type == flash.events.Event.RESIZE) { if (this._-2GU) { this._-yu(this._-2GU); } } return; } The next characters could be ;, (, ), dot, comma, space, :, etc.

  • cURL Affects Cookie Retrieval in PHP?

    - by CJ
    I'm not sure if I'm asking this properly. I have two PHP pages located on the same server. The first PHP page sets a cookie with an expiration and the second one checks to see if that cookie was set. if it is set, it returns "on". If it isn't set, it returns "off". If I just run the pages like "www.example.com/set_cookie.php" AND "www.example.com/is_cookie_set.php" I get an "on" from is_cookie_set.php. Heres the problem, on the set_cookie.php file I have a function called is_set. This function executes the following cURL and returns the contents ("on" or "off"). Unfortunately, the contents are always returned as "off". however, if I check the file manually ("www.example.com/is_cookie_set.php") I can see that the cookie was set. Heres the function : <?php function is_set() { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'http://example.com/is_cookie_set.php'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $contents = curl_exec ($ch); curl_close ($ch); echo $contents; } ?> Please note, I'm not using cURL to GET or SET cookies, only to check a page that checks if the cookie was set. I've looked into CURLOPT_COOKIEJAR, and CURLOPT_COOKIEFILE, but I believe those are for setting cookies via cURL and I don't want to do this.

  • Reading and writing to files simultaneously?

    - by vipersnake005
    Moved the question here. Suppose, I want to store 1,000,000,000 integers and cannot use my memory. I would use a file(which can easily handle so much data ). How can I let it read and write and the same time. Using fstream file("file.txt', ios::out | ios::in ); doesn't create a file, in the first place. But supposing the file exists, I am unable to use to do reading and writing simultaneously. WHat I mean is this : Let the contents of the file be 111111 Then if I run : - #include <fstream> #include <iostream> using namespace std; int main() { fstream file("file.txt",ios:in|ios::out); char x; while( file>>x) { file<<'0'; } return 0; } Shouldn't the file's contents now be 101010 ? Read one character and then overwrite the next one with 0 ? Or incase the entire contents were read at once into some buffer, should there not be atleast one 0 in the file ? 1111110 ? But the contents remain unaltered. Please explain. Thank you.

  • What is the best way to properly test object equality against an array of objects?

    - by radesix
    My objective is to abort the NSXMLParser when I parse an item that already exists in cache. The basic flow of the program works like this: 1) Program starts and downloads an XML feed. Each item in the feed is represented by a custom object (FeedItem). Each FeedItem gets added to an array. 2) When the parsing is complete the contents of the array (all FeedItem objects) are archived to the disk. The next time the program is executed or the feed is refreshed by the user I begin parsing again; however, since a cache (array) now exists as each item is parsed I want to see if the object exists in the cache. If it does then I know I have downloaded all the new items and no longer need to continue parsing. What I am learning, I think, is that I can't use indexOfObject or indexOfObjectIDenticalTo: because these really seem to be checking to see that the objects are using the same memory address (thus identical). What I want to do is see if the contents of the object are equal (or at least some of the contents). I've done some research and found that I can override the IsEqual method; however, I really don't want to iterate/enumerate through the entire cache contents table for every newly parsed XML FeedItem. Is iterating through the collection and testing each one for equality the only way to do this or is there a better technique I am not aware of? Currently I am using the following code though I know it needs to change: NSUInteger index = [self.feedListCache.feedList indexOfObject:self.currentFeedItem]; if (index == NSNotFound) { }

  • Customize the Five Windows Folder Templates

    - by Mark Virtue
    Are you’re particular about the way Windows Explorer presents each folder’s contents? Here we show you how to take advantage of Explorer’s built-in templates, which cuts down the time it takes to do customizations. Note: The techniques in this article apply to Windows XP, Vista, and Windows 7. When opening a folder for the first time in Windows Explorer, we are presented with a standard default view of the files and folders in that folder. It may be that the items are presented are perfectly fine, but on the other hand, we may want to customize the view.  The aspects of it that we can customize are the following: The display type (list view, details, tiles, thumbnails, etc) Which columns are displayed, and in which order The widths of the visible columns The order in which the files and folders are sorted Any file groupings Thankfully, Windows offers us a shortcut.  A particular folder’s settings can be used as a “template” for other, similar folders.  In fact, we can store up to five separate sets of folder presentation configurations.  Once we save the settings for a particular template, that template can then be applied to other folders. Customize Your First Folder We’ll start by setting up the first of our templates – the default one.  Once we create this template and apply it, the vast majority of the folders in our file system will change to match it, so it’s important that we set it up very carefully.  The first step in creating and applying the template is to customize one folder with the settings that all the rest will have. Choose a folder that is typical of the folders that you wish to have this default template.  Select it in Windows Explorer.  To ensure that it is a suitable candidate, right-click the folder name and select Properties, then go to the Customize tab.  Ensure that this folder is marked as General Items.  If it is not, either choose a different folder or select General Items from the list. Click OK.  Now we’re ready to customize our first folder. Changing the way one single folder is presented is straightforward.  We start with the folder’s display type.  Click the Change your view button in the top-right corner of every Explorer window. Each time you click the button, the folder’s view cycles to the next view type.  Alternatively you can click the little down-arrow next to the button to see all the display types at once, and select the one you want. Click the view you want, or drag the slider next to the one you want. If you have chosen Details, then the next thing you may wish to change is which columns are displayed, and the order of these.  To choose which columns are displayed, simply right-click on any column heading.  A list of the columns currently being display appears. Simply uncheck a column if you don’t want it displayed, and check the columns that you want displayed.  If you want some information displayed about your files that is not listed here, then click the More… button for a full list of file attributes. There’s a lot of them! To change the order of the columns that are currently being displayed, simply click on a column heading and drag it to where you think it should be.  To change the width of a column, click the line that represents the right-hand edge of the column and drag it left or right. To sort by a column, click once on that column.  To reverse the sort-order, click that same column again. To change the groupings of the files in the folder, right-click in a blank area of the folder, select Group by, and select the appropriate column. Apply This Default Template to All Similar Folders Once you have the folder exactly the way you want it, we now use this folder as our default template for most of the folders in our file system.  To do this, ensure that you are still in the folder you just customized, and then, from the Organize menu in Explorer, click on Folder and search options. Then select the View tab and click the Apply to Folders button. After you’ve clicked OK, visit some of the other folders in your file system.  You should see that most have taken on these new settings. What we’ve just done, in effect, is we have customized the General Items template.  This is one of five templates that Windows Explorer uses to display folder contents.  The five templates are called (in Windows 7): General Items Documents Pictures Music Videos When a folder is opened, Windows Explorer examines the contents to see if it can automatically determine which folder template to use to display the folder contents.  If it is not obvious that the folder contents falls into any of the last four templates, then Windows Explorer chooses the General Items template.  That’s why most of the folders in your file system are shown using the General Items template. Changing the Other Four Templates If you want to adjust the other four templates, the process is very similar to what we’ve just done.  If you wanted to change the “Music” template, for example, the steps would be as follows: Select a folder that contains music items Apply the existing Music template to the folder (even if it doesn’t look like you want it to) Customize the folder to your personal preferences Apply the new template to all “Music” folders A fifth step would be:  When you open a folder that contains music items but is not automatically displayed using the Music template, you manually select the Music template for that folder. First, select a folder that contains music items.  It will probably be displayed using the existing Music template: Next, ensure that it is using the Music template.  If it’s not, then manually select the Music template. Next, customize the folder to suit your personal preferences (here we’ve added a couple of columns, and sorted by Artist). Now we can set this view to be our Music template.  Choose Organize, then the View tab, and click the Apply to Folders button. Note: The only folders that will inherit these settings are the ones that are currently (or will soon be) using the Music template. Now, if you have any folder that contains music items, and you want it to inherit all of these settings, then right-click the folder name, choose Properties, and select that this folder should use the Music template.  You can also cehck the box entitled Also apply this template to all subfolders if you want to save yourself even more time with all the sub-folders. Conclusion It’s neat to be able to set up templates for your folder views like this.  It’s a shame that Microsoft didn’t take the concept just a little further and allow you to create as many templates as you want.
