  • PHP Strange error "0:". Possible Object syntax problem?

    - by Michael Stone
    I'm trying to transfer a site from one hosting company to another. I was using 000webhost until the client had hosting and a domain. Now that the client has their domain and hosting, using FatCow.com, I can not for the life of me, debug my PHP code. I'm not getting any errors. I have a successful DB connection. If you procedurally display data, it works, but when I try to use my original objects, something is breaking and just returns "0:". I have all errors on. On old server where the site worked: PHP Version 5.2.11 MySQL Version: 5.0.81 On new server where I get the "0:": PHP Version 5.2.12 MySQL Version 5.0.32 I've setup a test page to test just the output of the variables with the DB connection. Below is my code: <?php error_reporting(E_ALL); ini_set('display_errors', '1'); try { $link = mysql_connect('connectionstring', 'username', 'password'); if (!$link) { die('Could not connect: ' . mysql_error()); } else{ $db = mysql_select_db('a8210422_lit'); } if($db){ include_once('admin/classes/clsPOW.php'); include_once('admin/classes/clsProviders.php'); $pow = new POW(); $prov = new Providers(); $new = $pow->getNew(); $newAr = $new->val(); $get = $prov->getAll($newAr['providerId']); $getAr = $get->val(); $img = $getAr['image']; $name = $getAr['provider']; $desc = $getAr['description']; $zip = $getAr['zip']; $web = $getAr['link']; if($zip==0){ $zip = "Unavailable"; } print $img; print $name; print $desc; print $zip; print $web; } else{ print 'fail!'; } } //catch exception catch(Exception $e) { echo 'Message: ' .$e->getMessage(); } ?>

  • How to create an instance of object with RTTI in Delphi 2010?

    - by Paul
    As we all known, when we call a constructor of a class like this: instance := TSomeClass.Create; The Delphi compiler actually do the following things: Call the static NewInstance method to allocate memory and initialize the memory layout. Call the constructor method to perform the initialization of the class Call the AfterConstruction method It's simple and easy to understand. but I'm not very sure how the compiler handle exceptions in the second and the third step. It seems there are no explicit way to create an instance using a RTTI constructor method in D2010. so I wrote a simple function in the Spring Framework for Delphi to reproduce the process of the creation. class function TActivator.CreateInstance(instanceType: TRttiInstanceType; constructorMethod: TRttiMethod; const arguments: array of TValue): TObject; var classType: TClass; begin TArgument.CheckNotNull(instanceType, 'instanceType'); TArgument.CheckNotNull(constructorMethod, 'constructorMethod'); classType := instanceType.MetaclassType; Result := classType.NewInstance; try constructorMethod.Invoke(Result, arguments); except on Exception do begin if Result is TInterfacedObject then begin Dec(TInterfacedObjectHack(Result).FRefCount); end; Result.Free; raise; end; end; try Result.AfterConstruction; except on Exception do begin Result.Free; raise; end; end; end; I feel it maybe not 100% right. so please show me the way. Thanks!

  • Database: relational/not relational/object oriented... What to choose?

    - by Damian
    I'm porting a website that I made for app engine to run on a dedicated server. It is coded in java and I'm looking for a database to replace google datastore. My first thougt was MySql because everybody uses it, but i dont like SQL and I think I would feel more comfortable using OODB or anything else. With google datastore I could modify my models and don't worry about the database definition at all. I know using MySql that isn't possible. And I don't want to miss that. And if I use a OODB, which should I use? What about performance compared to MySql? Well, any idea or tip will really help me since I know nothing about databases.

  • How can I ensure that a Java object (containing cryptographic material) is zeroized?

    - by Jeremy Powell
    My concern is that cryptographic keys and secrets that are managed by the garbage collector may be copied and moved around in memory without zeroization. As a possible solution, is it enough to: public class Key { private char[] key; // ... protected void finalize() throws Throwable { try { for(int k = 0; k < key.length; k++) { key[k] = '\0'; } } catch (Exception e) { //... } finally { super.finalize(); } } // ... }

  • How to get a reference to a method's caller object from within the method in Objective-C

    - by shakeelw
    Hi guys. I have a few text fields and text views on my application's view. The keyboard comes up when I click in anyone of them. I have a method that gets called when any one of these objects is tapped in. However, I would like the method to execute its code only if the a certain Text Field(s) or a certain Text View(s) is tapped in. I would therefore like to have something like this in the method body: { if(currentField != mySpecialField) {return;} //Rest of the method code... } Now, my question is, how do I get a reference to the currently tapped in field so that I can perform the if-check. Thanks guys. I'm a total noobee in Objective-C. :(

  • OpenGL ES - how to keep some object at a fixed size?

    - by OMH
    I'm working on a little game in OpenGL ES. In the background, there is a world/map. The map is just a large texture. Zoom/pinch/pan is used to move around. And I'm using glOrthof (left, right, bottom, top, zNear, zFar) to implement the zoom/pinch. When I zoom in, the sprites on top of the map is also zoomed in. But I would like to have some sprites stay at a fixed size. I could probably calculate a scale factor, depending on the parameters to glOrthof, but there must be a more natural and straightforward way of doing that, instead of scaling the sprites down when I zoom in. If I add some text or some GUI elements on top of the map, they should definately have a fixed size. Is there a solution to do this, or do I have to leave fixed values in glOrthof and implement zoom/pinch in another way? EDIT: To be more clear: I want sprites that zoom in/out along with the map, but stay at the same size. I have some elements that are like the pins on the iPhone's map application. When you zoom, the pins stay the same size, but move around on the screen to stay on the same spot on the map. That is mainly what I want a solution for. Solutions for this already came below, thanks!

  • Why am I losing my characters from my html string when trying to add html dynamically using javascri

    - by Hamman359
    I have a page that I am trying to dynamically add some links to. The links are getting added to the page fine, but the '[' and ']' at either end of the line are getting dropped. The code from my .js file is: var html = "[ <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove </a> ]"; $(html).appendTo("#id123"); The result I want is: [ <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove</a> ] The result I'm getting is: <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove</a> If I wrap the line in a <span> tag like so: var html = "<span>[ <a href='#'>Change</a>&nbsp;|&nbsp;<a href='#'>Remove </a> ]</span>"; $(html).appendTo("#id123"); it renders as expected. I set a breakpoint on the code and checked the html var right before the .appendTo and it contains the '[' and ']'. Anyone know why this is happening? Are '[' and ']' special character that need escaped and I'm just forgetting that fact?

  • How to change object positions in an android layout?

    - by Pedro Santos
    Hi, I'm currently working on a very simple aplication, and I intended to make it change the visual aspect depending on the screen size. The application just has 6 buttons like this: http://www.freeimagehosting.net/uploads/e1efb4c4d0.jpg I'm using the AbsoluteLayout, and changing the x and y of the buttons with the methods offsetLeftAndRight and offsetTopAndBottom. I'm not changing the layout of the buttons in the xml file, so the all start in the same place. However, if I use this methods inside the onClickMethod they sometimes appear where I want them, sometimes don't (can't figure out why), but if i use them in the onCreate method, nothing happens. Can someone point me in the right direction? Thanks

  • The ultimate .NET file and directory utility library?

    - by Serge van den Oever
    I find myself writing file and directory utility functions all the time, and I was wondering if there is good file and directory library that already implements a more extensive set than available by default in System.IO. The kind of functions I'm looking for is things like: public static void GetTemporaryDirectory() { string tempDirectory = Path.Combine(Path.GetTempPath(), Path.GetRandomFileName()); Directory.CreateDirectory(tempDirectory); return tempDirectory; } public static void CreateEmptyFile(string filename) { File.Create(filename).Dispose(); } public static void CreateEmptyFile(string path, string filename) { File.Create(Path.Combine(path, filename)).Dispose(); } public static void CreateDirectory(string path) { Directory.CreateDirectory(path); } public static void CreateDirectory(string path, string childpath) { Directory.CreateDirectory(Path.Combine(path, childpath)); }

  • How do I connect from an XPCOM object to a GStreamer plugin in a Songbird addon?

    - by utnapistim
    Hi all, I am writing a Songbird addon, with three parts: XUL (javascript), a GStreamer filter and an XPCOM addon. I am interested in accessing the GStreamer layer from my XPCOM component. If anyone knows any resources on how to do that I'd be grateful. Specifically, I need documentation or examples on accessing the GStreamer functionality from within my addon (building a GST pipeline and running a file through it, from my XPCOM component (C++). Thanks :)

  • How do I draw a filled circle onto a graphics object in a hexadecimal colour?

    - by George Powell
    I need to draw a circle onto a bitmap in a specific colour given in Hex. The "Brushes" class only gives specific colours with names. Bitmap bitmap = new Bitmap(20, 20); Graphics g = Graphics.FromImage(bitmap); g.FillEllipse(Brushes.AliceBlue, 0, 0, 19, 19); //The input parameter is not a Hex //g.FillEllipse(new Brush("#ff00ffff"), 0, 0, 19, 19); <<This is the kind of think I need. Is there a way of doing this? The exact problem: I am generating KML (for Google earth) and I am generating lots of lines with different Hex colours. The colours are generated mathematically and I need to keep it that way so I can make as many colours as I want. I need to generate a PNG icon for each of the lines that is the same colour exactly.

  • How extensive is an Object in CakePHP model linkage?

    - by Andre
    I was hoping someone with an understanding on CakePHP could shed some light on a question I've been having. Here's my scenario, I have a User this User has a Company which in turn has many Department and many Address. If I were to get a User could I expect to have access to the Company and all models associated with that Company? So would $user['Company']['Department'][0] or $user['Company']['Address'][0] be possible? Which brings me back to the original question, how extensive is the linkage between models?

  • Which is better: string html generation or jquery DOM element creation?

    - by Ed Woodcock
    Ok, I'm rewriting some vanilla JS functions in my current project, and I'm at a point where there's a lot of HTML being generated for tooltips etc. My question is, is it better/preferred to do this: var html = '<div><span>Some More Stuff</span></div>'; if (someCondition) { html += '<div>Some Conditional Content</div>'; } $('#parent').append(html); OR var html = $('<div/>').append($('<span/>').append('Some More Stuff')); if (someCondition) { html.append($('<div/>').append('Some conditionalContent'); } $('#parent').append(html); ?

  • Trouble Avoiding Microsoft Outlook's Email Warning

    - by talbright
    I have a set of records in Microsoft Access that I am trying to send in an Email. The email feature works great. Except a warning message pops up every time a message is ready to send, and the user has to click "Allow" or "Deny" for every email sent. I looked up a workaround, and have been following the tutorial for it: http://www.everythingaccess.com/tutorials.asp?ID=Outlook-Send-E-mail-Without-Security-Warning. My problem is that when I put my message in the function it always returns false, and the message fails. Any help would be appreciated. Dim sendMail As Boolean Dim strMessage As String strMessage = Some Message sendMail = FnSafeSendEmail(![Email Id], "Subject", strMessage) The entire "FnSafeSendEmail" function can be found in the link provided. These are the parameters though. Public Function FnSendMailSafe(strTo As String, _ strCC As String, _ strBCC As String, _ strSubject As String, _ strMessageBody As String, _ Optional strAttachments As String) As Boolean The error is thrown on this line of the function. Dim blnSuccessful As Boolean blnSuccessful = objOutlook.FnSendMailSafe(strTo, strCC, strBCC, _ strSubject, strMessageBody, _ strAttachmentPaths)
