  • Session variables not getting set but only in Internet Explorer and not on all machines

    - by gaoshan88
    Logging into a site I'm working on functions as expected on my local machine but fails on the remote server but ONLY in Internet Explorer. The kicker is that it works in IE locally, just not on the remote machine. What in the world could cause this? I have stepped through the code on the remote machine and can see the entered login values being checked in the database, they are found and then a login function is called. This sets two $_SESSION variables and redirects to the main admin page. However, in IE only (and not when run on local machine... this is key) the $_SESSION variables are not present by the time you get to the main admin page. var_dump($_SESSION) gives me what I expect on every browser when I am running this in my local environment and in every browser except IE 6, 7 and 8 when run on the remote server (where I get a null value as if nothing has been set for $_SESSION). This really has me stumped so any advice is appreciated. For an example... in IE, run locally, var_dump gives me: array 'Username' => string 'theusername' length=11 'UserID' => string 'somevalue' length=9 Run on the remote server (IE only... works fine in other browsers) var_dump gives me: array(0){} Code: $User = GetUser($Username, $Password); if ($User->UserID <> "") { // this works so we call Login()... Login($User); // this also works and gives expected results. on to redirect... header("Location: index.php"); // a var_dump at index.php shows that there is no session data at all in IE, remotely. } else { header("Location: login.php"); } function Login($data) { $_SESSION['Username'] = $data->Username; $_SESSION['UserID'] = $data->UserID; // a var dump here gives the expected data in every browser }

  • NSTableView don't display data

    - by Tomas Svoboda
    HI, I have data in NSMutableArray and I want to display it in NSTableView, but only the number of cols has changed. This use of NSTableView is based on tutorial: http://www.youtube.com/watch?v=5teN5pMf-rs FinalImageBrowser is IBOutlet to NSTableView @implementation AppController NSMutableArray *listData; - (void)awakeFromNib { [FinalImageBrowser setDataSource:self]; } - (IBAction)StartReconstruction:(id)sender { NSMutableArray *ArrayOfFinals = [[NSMutableArray alloc] init]; //Array of list with final images NSString *FinalPicture; NSString *PicNum; int FromLine = [TextFieldFrom intValue]; //read number of start line int ToLine = [TextFieldTo intValue]; //read number of finish line int RecLine; for (RecLine = FromLine; RecLine < ToLine; RecLine++) //reconstruct from line to line { Start(RecLine); //start reconstruction //Create path of final image FinalPicture = @"FIN/final"; PicNum = [NSString stringWithFormat: @"%d", RecLine]; FinalPicture = [FinalPicture stringByAppendingString:PicNum]; FinalPicture = [FinalPicture stringByAppendingString:@".bmp"]; [ArrayOfFinals addObject:FinalPicture]; // add path to array } listData = [[NSMutableArray alloc] init]; [listData autorelease]; [listData addObjectsFromArray:ArrayOfFinals]; [FinalImageBrowser reloadData]; NSBeep(); //make some noise NSImage *fin = [[NSImage alloc] initWithContentsOfFile:FinalPicture]; [FinalImage setImage:fin]; } - (int)numberOfRowsInTableView:(NSTableView *)tv { return [listData count]; } - (id)tableView:(NSTableView *)tv objectValueFromTableColumn:(NSTableColumn *)tableColumn row:(int)row { return (NSString *)[listData objectAtIndex:row]; } @end when the StartReconstruction end the number of cols have changed right, but they're empty. When I debug app, items in listData is rigth. Thanks

  • PHP, MySQL prepared statements - can you use results of execute more than once by calling data_seek(

    - by Carvell Fenton
    Hello, I have a case where I want to use the results of a prepared statement more than once in a nested loop. The outer loop processes the results of another query, and the inner loop is the results of the prepared statement query. So the code would be something like this (just "pseudoish" to demonstrate the concept): // not showing the outer query, it is just a basic SELECT, not prepared statement // we'll call it $outer_query $obj_array = array(); // going to save objects in this $ids = array(18,19,20); // just example id numbers $query = "SELECT field1, field2 FROM table1 WHERE id=?"; $stmt = $db->prepare($query); foreach ($ids as $id) { $stmt->bind_param("i", $id); $stmt->execute(); $stmt->bind_result($var1, $var2); $stmt->store_result(); // I think I need this for data_seek while ($q1 = $outer_query->fetch_object()) { while ($stmt->fetch()) { if ($q1->field1 == $var1) { // looking for a match $obj = new stdClass(); $obj->var1 = $var1; $obj->var2 = $var2; $obj_array[] = $obj; $stmt->data_seek(0); // reset for outer loop break; // found match, so leave inner } } } } The problem I seem to be experiencing is that the values are not getting bound in the variables as I would expect after the first time I use fetch in the inner loop. Specifically, in one example I ran with 3 ids for the foreach, the first id was processed correctly, the second was processed incorrectly (matches were not found in the inner loop even though they existed), and then the third was processed correctly. Is there something wrong with the prepared statment function calls in the sequence I am doing above, or is this an invalid way to use the results of the prepared statement? Thanks.

  • Zend Framework/PHPUnit: How to Stub/Mock an object method that connects to a database?

    - by Andrew
    In my Zend Framework project, I have a form that I am testing. In my form, a multi-select element gets its options from a model, which gets the data from the database. public function init() { $this->addElement('select', 'Region_ID', array('multiOptions' => $this->getRegions())); } protected function getRegions() { $mapper = new Model_RegionMapper(); return $mapper->getFormSelectData(); //this method will try to connect to a database (or get another object that will connect to the database) } I tried copying the example in the PHPUnit documentation, but it doesn't seem to be working. public function setUp() { $stub = $this->getMock('Model_RegionMapper'); $stub->expects($this->any()) ->method('getFormSelectData') ->will($this->returnValue(array('testdata'))); } public function testFoo() { //this will fail $form = new My_Form(); } The test fails because it is trying to find a table in the database that doesn't exist. But I don't want it to connect to the database at all. How do I correctly stub/mock this method so that it doesn't call the database?

  • Why does the '#weight' property sometimes not have any effect in Drupal forms?

    - by Adrian
    Hello, I'm trying to create a node form for a custom type. I have organic groups and taxonomy both enabled, but want their elements to come out in a non-standard order. So I've implemented hook_form_alter and set the #weight property of the og_nodeapi subarray to -1000, but it still goes after taxonomy and menu. I even tried changing the subarray to a fieldset (to force it to actually be rendered), but no dice. I also tried setting $form['taxonomy']['#weight'] = 1000 (I have two vocabs so it's already being rendered as a fieldset) but that didn't work either. I set the weight of my module very high and confirmed in the system table that it is indeed the highest module on the site - so I'm all out of ideas. Any suggestions? Update: While I'm not exactly sure how, I did manage to get the taxonomy fieldset to sink below everything else, but now I have a related problem that's hopefully more manageable to understand. Within the taxonomy fieldset, I have two items (a tags and a multi-select), and I wanted to add some instructions in hook_form_alter as follows: $form['taxonomy']['instructions'] = array( '#value' => "These are the instructions", '#weight' => -1, ); You guessed it, this appears after the terms inserted by the taxonomy module. However, if I change this to a fieldset: $form['taxonomy']['instructions'] = array( '#type' => 'fieldset', // <-- here '#title' => 'Instructions', // <-- and here for good measure '#value' => "These are the instructions", '#weight' => -1, ); then it magically floats to the top as I'd intended. I also tried textarea (this also worked) and explicitly saying markup (this did not). So basically, changing the type from "markup" (the default IIRC) to "fieldset" has the effect of no longer ignoring its weight.

  • Symfony2 entity field type alternatives to "property" or "__toString()"?

    - by Polmonino
    Using Symfony2 entity field type one should specify property option: $builder->add('customers', 'entity', array( 'multiple' => true, 'class' => 'AcmeHelloBundle:Customer', 'property' => 'first', )); But sometimes this is not sufficient: think about two customers with the same name, so display the email (unique) would be mandatory. Another possibility is to implement __toString() into the model: class Customer { public $first, $last, $email; public function __toString() { return sprintf('%s %s (%s)', $this->first, $this->last, $this->email); } } The disadvances of the latter is that you are forced to display the entity the same way in all your forms. Is there any other way to make this more flexible? I mean something like a callback function: $builder->add('customers', 'entity', array( 'multiple' => true, 'class' => 'AcmeHelloBundle:Customer', 'property' => function($data) { return sprintf('%s %s (%s)', $data->first, $data->last, $data->email); }, ));

  • Linking a template class using another template class (error LNK2001)

    - by Luís Guilherme
    I implemented the "Strategy" design pattern using an Abstract template class, and two subclasses. Goes like this: template <class T> class Neighbourhood { public: virtual void alter(std::vector<T>& array, int i1, int i2) = 0; }; and template <class T> class Swap : public Neighbourhood<T> { public: virtual void alter(std::vector<T>& array, int i1, int i2); }; There's another subclass, just like this one, and alter is implemented in the cpp file. Ok, fine! Now I declare another method, in another class (including neighbourhood header file, of course), like this: void lSearch(/*parameters*/, Neighbourhood<LotSolutionInformation> nhood); It compiles fine and cleanly. When starting to link, I get the following error: 1>SolverFV.obj : error LNK2001: unresolved external symbol "public: virtual void __thiscall lsc::Neighbourhood<class LotSolutionInformation>::alter(class std::vector<class LotSolutionInformation,class std::allocator<class LotSolutionInformation> > &,int,int)" (?alter@?$Neighbourhood@VLotSolutionInformation@@@lsc@@UAEXAAV?$vector@VLotSolutionInformation@@V?$allocator@VLotSolutionInformation@@@std@@@std@@HH@Z)

  • Presenting collection of structures of strings in grid or similar in WPF - Example? Ideas?

    - by Andrew
    Hi, I have a collection of structures. The structure is just some strings. Example public struct ReportLine { public string Name; public string Address; public string Phone; ...// about 10 other strings } I can't change this part. What I want to do is display it in a simple grid or simlar in WPF. My only requirements are: a) need column headers b) rows must alternate in color c) columns big enough to hold largest datum (which is not know until run time) Can someone point me to an example to get me started? Is the GridView the way to go? Or DataGrid? Or perhaps just the grid? I have the book Pro WPF in C# 2008 and it covers binding ListBox's to collections, but the collections always seem to be collections of one field (ex. a collection of 40 names). Here I have a collection (an array in fact) of a structure. How do I setup the databinding? As you can see, I'm new to this and probably would most benefit from a reference to an article. I've found articles covering collections of 1 field, but no examples covering binding to an array of structures. Also, my intitial research indicates c) can't be easily done, if you demand that the column is big enough for all the data in that column, not just the visible data. Thanks, dave

  • jquery accessing dynamic class selectors

    Given the following html rendering; <fieldset id="fld_Rye"> <legend>7 Main St.</legend> <div> <table> <tr> <th class="wideCol"><b><i>Service Description</i></b></th> <th class="wideCol"><b><i>Service Name</i></b></th> <th class="normalPlusWidth"><b><i>Contact Name</i></b></th> </tr> <ItemTemplate> <tr class=""> <td class="servDesc">&nbsp;<b>Plumbing Services</b></td> <td class="servName">&nbsp;<b>Flynnsters's Plumbing</b></td> <td class="servContact">&nbsp;<b>Jim Flynnster</b></td> </tr> </ItemTemplate> I am trying to access all the td's with a class of servDesc, get their width into an array and get the max width from that array to reset the css width of that class using jquery on page load. I cant seem to get the right selector for those tags, and I've tried at least 50 variations. My latest try; var maxTdWidth; var servDescCols = []; $("#fld_Rye td#servDesc").each(function () { alert("found one"); servDescCols.push(this.width()); }); maxTdWidth = Math.max.apply(Math, servDescCols);

  • Using an SHA1 with Micrsoft CAPI

    - by Erik Jõgi
    Hello, I have an SHA1 hash and I need to sign it. The CryptSignHash() method requires a HCRYPTHASH handle for signing. I create it and as I have the actual hash value already then set it: CryptCreateHash(cryptoProvider, CALG_SHA1, 0, 0, &hash); CryptSetHashParam(hash, HP_HASHVAL, hashBytes, 0); The hashBytes is an array of 20 bytes. However the problem is that the signature produced from this HCRYPTHASH handle is incorrect. I traced the problem down to the fact that CAPI actually doesn't use all 20 bytes from my hashBytes array. For some reason it thinks that SHA1 is only 4 bytes. To verify this I wrote this small program: HCRYPTPROV cryptoProvider; CryptAcquireContext(&cryptoProvider, NULL, NULL, PROV_RSA_FULL, 0); HCRYPTHASH hash; HCRYPTKEY keyForHash; CryptCreateHash(cryptoProvider, CALG_SHA1, keyForHash, 0, &hash); DWORD hashLength; CryptGetHashParam(hash, HP_HASHSIZE, NULL, &hashLength, 0); printf("hashLength: %d\n", hashLength); And this prints out hashLength: 4 ! Can anyone explain what I am doing wrong or why Microsoft CAPI thinks that SHA1 is 4 bytes (32 bits) instead of 20 bytes (160 bits). Thank you.

  • How do I get Facebook Application Login to work

    - by Javaaaa
    I just started making an application for Facebook, however I ran into problem early on. The first step I want people to do is to give permission to access their profile. All over the web are examples of how to do this with: $user_id = $facebook->require_login(); However, this is the way it works using the Old PHP API. I have downloaded and installed the new one in my application folder and it is not working anymore. My question is (and i really have been searching for an answer for a long time) what is the code to do this with the new API? (and related question: is it better to use the old API, or learn to work with the new one when I am just starting making apps right now) I have this code now; <?php // Awesome Facebook Application // // Name: - // require_once 'facebook-php-sdk/src/facebook.php'; // Create our Application instance. $facebook = new Facebook(array( 'appId' => $app_id, 'secret' => $app_secret, 'cookie' => true )); $loginUrl = $facebook->getLoginUrl(array( 'req_perms' => 'email,user_birthday,publish_stream,sms,status_update,user_location' )); echo "<p>hello, <fb:name uid=\"$user_id\" useyou=\"false\" />!</p>"; ?>

  • RTTI Delphi Create as TValue an n-dimensional matrix.

    - by user558126
    Good day, I had tried to make recurrent function to return a TValue as a n-dimensional. matrix(2D, 3D, 4D...) for example, this procedure will show a n-dimensional matrix(it will list all elements from a n-dimensional matrix as TValue variable): Procedure Show(X:TValue); var i:integer; begin if x.IsArray then begin for i:=0 to x.GetArrayLength-1 do show(x.GetArrayElement(i)); writeln; end else write(x.ToString,' '); end; I don't understand how to create a function to create from a TValue an n-dimensional matrix. For example i need a Function CreateDynArray(Dimensions:array of integer; Kind:TTypeKind):TValue; and the function will return a TValue which is a dynamic array how contain the dimenssions for example: Return=CreateDynArray([2,3],tkInteger); will return a TValue as tkDynArray and if i will show(Return) will list 0 0 0 0 0 0 Thank you very much, and have a nice day!

  • Simple average calculation

    - by sasquatch90
    I'm trying to write program calculating average of given numbers stored in an array. Amount of numbers should be not more than 100, and user should input them until a !int variable is given : #include <iostream> #include <conio.h> using namespace std; double average(int tab[], int i){ int sum=0; for(int j=0; j<i; ++j){ sum+=tab[j]; } return (double)sum/i; } int main() { int tab[100]; int n=0; int number=0; do { if(n < 100){ cout << "Give " << n+1 << " number : "; cin >> number; tab[n]=number; number=0; ++n; } else{ break; } } while( !isdigit(number) ); cout << average(tab, n) << endl; getch(); return 0; } Why after giving char, it prints me 'Give n number:' for all empty cells of my array ? It should end and use only given numbers.

  • Multithreading using pthread in C++ with shared variables

    - by Saviour Self
    I'm new to threading (and C/C++ for that matter), and I'm attempting to use multiple threads to access shared variables. In the main, I've created a variable char inputarray[100]; Thread 1: This thread will be reading data from stdin in 2 byte bursts, and appending them to the inputarray. (input by feeding a file in) Thread 2: This thread will be reading data 1 byte at a time, performing a calculation, and putting its data into an output array. Thread 3: This thread will be outputting data from the output array in 2 byte bursts. (stdout) I've attempted the input part and got it working by passing a struct, but would like to do it without using a struct, but it has been giving me problems. If I can get input down, I'm sure I'll be able to use a similar strategy to complete output. Any help would be greatly appreciated. Below is a rough template for the input thread. #include <stdio.h> #include <pthread.h> using namespace std; void* input(void* arg) { char reading[3]; fread(reading,1,2,stdin); //append to char inputarray[]..??? } int main() { char inputarray[100]; pthread_t t1; pthread_create(&t1, NULL, &input, &inputarray); void *result; pthread_join(t1,&result); return 0; }

  • fastest way to check to see if a certain index in a linq statement is null

    - by tehdoommarine
    Basic Details I have a linq statement that grabs some records from a database and puts them in a System.Linq.Enumerable: var someRecords = someRepoAttachedToDatabase.Where(p=>true); Suppose this grabs tons (25k+) of records, and i need to perform operations on all of them. to speed things up, I have to decided to use paging and perform the operations needed in blocks of 100 instead of all of the records at the same time. The Question The line in question is the line where I count the number of records in the subset to see if we are on the last page; if the number of records in subset is less than the size of paging - then that means there are no more records left. What I would like to know is what is the fastest way to do this? Code in Question int pageSize = 100; bool moreData = true; int currentPage = 1; while (moreData) { var subsetOfRecords = someRecords.Skip((currentPage - 1) * pageSize).Take(pageSize); //this is also a System.Linq.Enumerable if (subsetOfRecords.Count() < pageSize){ moreData = false;} //line in question //do stuff to records in subset currentPage++; } Things I Have Considered subsetOfRecords.Count() < pageSize subsetOfRecords.ElementAt(pageSize - 1) == null (causes out of bounds exception - can catch exception and set moreData to false there) Converting subsetOfRecords to an array (converting someRecords to an array will not work due to the way subsetOfRecords is declared - but I am open to changing it) I'm sure there are plenty of other ideas that I have missed.

  • How to read the birthday_date from the Facebook API

    - by Steve
    I have been chasing my tail on this! And it should be so simple!! I have an app in FaceBook that is working fine. However, I need to get the user's birth date. I have successfully got the request for extended permissions, but cannot get the birthday_date out and into a variable/store in database. <?php require_once('facebook.php'); $facebook = new Facebook(array( 'appId' => 'xxxxx', 'secret' => 'yyyyyyy', 'cookie' => true )); if ($facebook->getSession()) { $uid = $facebook->getUser(); $fbme = $facebook->api('/me'); } else { $params = array( 'fbconnect'=>0, 'canvas'=>1, 'req_perms'=>'publish_stream','email','user_location','user_birthday' ); $loginUrl = $facebook->getLoginUrl($params); print "<script type='text/javascript'>top.location.href = '$loginUrl';</script>"; } $session = $facebook->getSession(); $token = $session['access_token']; I would be very grateful if someone could show me the PHP code that reads the extended permissions and places the results into variables. Thanks Steve

  • Avoid an "out of memory error" in Java(eclipse), when using large data structure?

    - by gnomed
    OK, so I am writing a program that unfortunately needs to use a huge data structure to complete its work, but it is failing with a "out of memory error" during its initialization. While I understand entirely what that means and why it is a problem, I am having trouble overcoming it, since my program needs to use this large structure and I don't know any other way to store it. The program first indexes a large corpus of text files that I provide. This works fine. Then it uses this index to initialize a large 2D array. This array will have nXn entries, where "n" is the number of unique words in the corpus of text. For the relatively small chunk I am testing it on(about 60 files) it needs to make approximately 30,000x30,000 entries. this will probably be bigger once I run it on my full intended corpus too. It consistently fails every time, after it indexes, while it is initializing the data structure(to be worked on later). Things I have done include: revamp my code to use a primitive "int[]" instead of a "TreeMap" eliminate redundant structures, etc... Also, I have run eclipse with "eclipse -vmargs -Xmx2g" to max out my allocated memory I am fairly confident this is not going to be a simple line of code solution, but is most likely going to require a very new approach. I am looking for what that approach is, any ideas? Thanks, B.

  • Rand(); with exclusion to and already randomly generated number..?

    - by Stefan
    Hey, I have a function which calls a users associated users from a table. The function then uses the rand(); function to chose from the array 5 randomly selected userID's however!... In the case where a user doesnt have many associated users but above the min (if below the 5 it just returns the array as it is) then it gives bad results due to repeat rand numbers... How can overcome this or exclude a previously selected rand number from the next rand(); function call. Here is the section of code doing the work. Bare in mind this must be highly efficient as this script is used everywhere. $size = sizeof($users)-1; $nusers[0] = $users[rand(0,$size)]; $nusers[1] = $users[rand(0,$size)]; $nusers[2] = $users[rand(0,$size)]; $nusers[3] = $users[rand(0,$size)]; $nusers[4] = $users[rand(0,$size)]; return $nusers; Thanks in advance!

  • passing string to a AJAX/JSON function

    I’m having trouble getting a AJAX/JSON function to work correctly. I had this function grabbing value from a drop down box but now I want to use an anchor tag to set it's value. I thought it would be easy to just use the onClick event to pass string to the function I was using for the drop down box but it doesn’t do anything. I’m stumped! Here how I set it up: 1st I add an onClick event… <a href="<?php echo Settings::get('app.webroot'); ?>?view=schedule&action=questions" onmouseout="MM_swapImgRestore();" onmouseover="MM_swapImage('bre','','template/images/schedule/bre_f2.gif',1) onclick="assignCallType('testing')";> 2nd I check main.js.php function assignCallType(type) { alert(type); //just for debugging new Request.JSON({ url: "ajax.php", onSuccess: function(rtndata,txt){ if (rtndata['STATUS'] != 'OK') alert('Error assigning call type to call'); }, onFailure: function (xhr) { alert('Error assigning call type to call'); } }).get({ 'action': 'assignCallType', 'call_type': type }); } 3rd Ajax.php: the variable is back in PHP and values don’t get added to the db, but I also didn’t get the alert from main.js.php if ($_GET['action'] == "assignCallType") { if ($USER->isInsideSales()) { $call_type = $_GET['call_type']; $_SESSION['callinfo']->setCallType($call_type); $_SESSION['callinfo']->save($callid); echo json_encode(array('STATUS'=>'OK')); } else { echo json_encode(array('STATUS'=>'DENIED')); } } Any idea where I am going wrong. The only difference between this and the working drop down is how the function was called, I used onchange="assignCallType(this.value)".

  • Plotting a graph with GD

    - by Nayena
    Here it goes. I have been thinking about this for a long time, and havent really been able to put up a proper way to do it yet. I havent implemented anything yet, as im still designing the thing. The idea is that i crawl a website for internal links, i got this settled, its easy, but after the crawling, i end up with an array with lots of links, and how many times those particular link appears on the site that i crawled (and how they're connected). With this huge array, i want to draw a graph somehow. Assuming i can handle the data correctly, the real question here is how i can draw this in a image by the use of the GD library. I figured if theres less than 12 elements, i can align them up on a unit circle spacing them up as a circle and then connecting them accordingly, so anything up to 12 elements shouldn't be a problem, but if theres more than 12, it could be awesome getting them lined up like this Or well, thats just a rough drawing, but i guess its just to prove a point. So i'm here looking for guidance or tips towards getting the math down to getting the stuff lined up in a good way. I have previously made bar-graphs, so i have little experience doing math with GD. If possible, id prefer not using some plotter-library - in the end, it gives me a better understanding on how things are supposed to be.

  • Getting Response From Jquery JSON

    - by Howdy_McGee
    I'm having trouble getting a response from my php jquery / json / ajax. I keep combining all these different tutorials together but I still can't seem to pull it all together since no one tutorial follow what I'm trying to do. Right now I'm trying to pass two arrays (since there's no easy way to pass associative arrays) to my jquery ajax function and just alert it out. Here's my code: PHP $names = array('john doe', 'jane doe'); $ids = array('123', '223'); $data['names'] = $names; $data['ids'] = $ids; echo json_encode($data); Jquery function getList(){ $.ajax({ type: "GET", url: 'test.php', data: "", complete: function(data){ var test = jQuery.parseJSON(data); alert(test.names[0]); alert("here"); } }, "json"); } getList(); In my html file all I'm really calling is my javascript file for debugging purposes. I know i'm returning an object but I'm getting an error with null values in my names section, and i'm not sure why. What am I missing? My PHP file returns {"names":["john doe","jane doe"],"ids":["123","223"]} It seems to be just ending here Uncaught TypeError: Cannot read property '0' of undefined so my sub0 is killing me.
