  • only update certain model attributes using Backbone.js

    - by Drew Dara-Abrams
    With Backbone, I'm trying to update and save to the server just one attribute: currentUser.save({hide_explorer_tutorial: 'true'}); but I don't want to send all the other attributes. Some of them are actually the output of methods on the server-side and so they are not actually true attributes with setter functions. Currently I'm using unset(attribute_name) to remove all the attributes that I don't want to update on the server. Problem is those attributes are then no longer available for local use. Suggestions on how to only save certain attributes to the server?

  • try/catch: errors or exceptions?

    - by Josh
    OK. I may be splitting hairs here, but my code isn't consistent and I'd like to make it so. But before I do, I want to make sure I'm going the right way. In practice this doesn't matter, but this has been bothering me for a while so I figured I'd ask my peers... Every time I use a try... catch statement, in the catch block I always log a message to my internal console. However my log messages are not consistent. They either look like: catch(err) { DFTools.console.log("someMethod caught an error: ",err.message); ... or: catch(ex) { DFTools.console.log("someMethod caught an exception: ",ex.message); ... Obviously the code functions properly either way but it's starting to bother me that I sometimes refer to "errors" and sometimes to "exceptions". Like I said, maybe I'm splitting hairs but which is the proper terminology? "Exception", or "Error"?

  • Right clicking on QHeaderView inside of QTreeView

    - by taynaron
    I've written a descendant of QTreeView with multiple columns. I want to create a popup menu that appears whe nthe user right-clicks over the column headers. I have tried catching signals from QTreeView for this, but QTreeView doesn't seem to emit signals on the headers. QTreeView.header() does. I therefore believe I must either: 1: connect one of QHeaderView's signals to a popup function - I have been unable to find a signal that is triggered on a single right click - I have tried sectionClicked, sectionHandleDoubleClicked, sectionDoubleClicked, sectionPressed (not surprised the double click functions didn't catch a single right click - but they do catch a double right click) self.header().sectionClicked.connect(self.headerMenu) self.header().sectionHandleDoubleClicked.connect(self.headerMenu) self.header().sectionDoubleClicked.connect(self.headerMenu) self.header().sectionPressed.connect(self.headerMenu) or, 2: write a descendant of QHeaderView with my own MousePressEvent function, and use that for my headers. I have so far been unsuccessful in connecting the new header class to the QTreeView descendant. I keep getting a Segmentation Fault on runtime, with no more explanation. #in DiceView's init, where DiceHeaders is the QHeaderView descendant self.setHeader(DiceHeaders()) Any ideas?

  • Find the minimum gap between two numbers in an AVL tree

    - by user1656647
    I have a data structures homework, that in addition to the regular AVL tree functions, I have to add a function that returns the minimum gap between any two numbers in the AVL tree (the nodes in the AVL actually represent numbers.) Lets say we have the numbers (as nodes) 1 5 12 20 23 21 in the AVL tree, the function should return the minimum gap between any two numbers. In this situation it should return "1" which is |20-21| or |21-20|. It should be done in O(1). Tried to think alot about it, and I know there is a trick but just couldn't find it, I have spent hours on this. There was another task which is to find the maximum gap, which is easy, it is the difference between the minimal and maximal number.

  • PHP/Cronjob: What is my Cronjobs problem?

    - by Marius
    Hello there, I have no idea whats going on. But I have a script that looks like this. Cron job refuses to run it: include_once 'class_lib/mime_mail/mimeDecode.php'; include_once 'class_lib/Mail/IMAPv2.php'; include_once 'inc-functions.php'; include_once "$_SERVER[DOCUMENT_ROOT]/class_lib/DbFuctioneer.php"; $dbFuctioneer = new DbFuctioneer(); Everything works well when I remove: $dbFuctioneer = new DbFuctioneer(); Even when DbFuctioneer() looks like this: <?php class DbFuctioneer { function dbCountMatches( $count) { return $count; } } Does Cron have a problem with Classes in his Jobs? Thank you for your time. Kind regards, Marius

  • Redmon's Run As User not loading user's enviroment variables

    - by catfish
    I'm attempting to use Redmon http://www.winimage.com/misc/redmon/ to send print jobs to a custom C# application. Redmon "runs" (actually the Print Spooler) as SYSTEM but has an option to Run As User to allow your application to run under the user that printed the job. The problem is that it doesn't appear to load the user's environment. So calling functions like Path.GetTempPath() points to \windows\temp instead of the user's. Also when attempting to run Outlook 2007+ via MAPI calls (to add attachments) it reports form errors due to, I think, the temp folder location. Is there a way to "reload" a profile or atleast get your environment vars within the Impersonated application? The only ideas I've had so far is to rebuild the vars directly from the registry, but I want to avoid this since it's a hack around (avoiding implementation details and all that). Or making a stub program that Redmon calls which then properly Run As User with full profile the custom application. Any other items or tricks?

  • Most efficient way to check if a date falls between two dates?

    - by Dave Jarvis
    Given: Start Month & Start Day End Month & End Day Any Year What SQL statement results in TRUE if a date lands between the Start and End days? 1st example: Start Date = 11-22 End Date = 01-17 Year = 2009 Specific Date = 2010-01-14 TRUE 2nd example: Start Date = 11-22 End Date = 11-16 Year = 2009 Specific Date = 2010-11-20 FALSE 3rd example: Start Date = 02-25 End Date = 03-19 Year = 2004 Specific Date = 2004-02-29 TRUE I was thinking of using the MySQL functions datediff and sign plus a CASE condition to determine whether the year wraps, but it seems rather expensive. Am looking for a simple, efficient calculation. Update The problem is the end date cannot simply use the year. The year must be increased if the end month/day combination happens before the start date. The start date is easy: Start Date = date( concat_ws( '-', year, Start Month, Start Day ) The end date is not so simple. Thank you!

  • When I make a database change, how do I know what needs to be removed and readded to the LinqToSql O

    - by Michael Maddox
    For example, I alter a column in a table to be not null from null. I need to then delete and readd the table. That part is pretty clear. What about views, functions, and stored procedures that access the table, especially that column in the table? I've tried running diffs against the files generated by SQLMetal with some limited success, but even with that it's fairly unclear. I know there is at least one commercial tool out there that claims to address this problem, but I am looking for something free. How are people dealing with this issue?

  • object won't die (still references to it that I can't find)

    - by user288558
    I'm using parallel-python and start a new job server in a function. after the functions ends it still exists even though I didn't return it out of the function (I used weakref to test this). I guess there's still some references to this object somewhere. My two theories: It starts threads and it logs to root logger. My questions: can I somehow findout in which namespace there is still a reference to this object. I have the weakref reference. Does anyone know how to detach a logger? What other debug suggestions do people have? here is my testcode: def pptester(): js=pp.Server(ppservers=nodes) js.set_ncpus(0) fh=file('tmp.tmp.tmp','w') tmp=[] for i in range(200): tmp.append(js.submit(ppworktest,(),(),('os','subprocess'))) js.print_stats() return weakref.ref(js) thanks in advance Wolfgang

  • Graceful degradation on iPhone

    - by Seva Alekseyev
    How do I write a program for iPhone (Objective C++) that runs on OS 2.0 but takes advantage of 3.0 features if they're available? Example: copy&paste (class UIPasteboard). Nice feature to have, but I don't want to kill backward compatibility. Do I compile against SDK v. 3 or v. 2? If the latter, how do I create an instance of UIPasteboard, considering it's not declared in the headers? If the former, won't some C-linkage functions cause "unresolved reference" upon loading under OS 2.0?

  • How to time-delay email deliveries?

    - by Michael D
    I'm currently learning about the Drupal email functions, such as drupal_mail and hook_mail, and hook_mail_alter, and I have a problem before me where I'll need to be able to queue emails for delayed delivery. For example, an event signup notification that needs to wait for an hour after the event was registered by a user. And that email has user specific data, so can't be just a generic template email... I'm using the MailQ module, mainly for it's logging capabilities, but I wonder if it (or something else) could be modified to add a configurable delay function? Any ideas?

  • fast algorithm implementation to sort very small set

    - by aaa
    hello. This is the problem I ran into long time ago. I thought I may ask your for your ideas. assume I have very small set of numbers (integers), 4 or 8 elements, that need to be sorted, fast. what would be the best approach/algorithm? my approach was to use the max/min functions. I guess my question pertains more to implementation, rather than type of algorithm. At this point it becomes somewhat hardware dependent , so let us assume Intel 64-bit processor with SSE3 . Thanks

  • SVN Delete with wildcard?

    - by David Lively
    I'm migrating a VSS repository to SVN and inadvertently included all of the _vti_cnf, *.scc files in the first check-in. I'd like to remove these from SVN. (Not permanently, of course - just in the HEAD). The application in question is quite large, and finding and deleting these files on a folder-by-folder basis will take forever. Suggestions? There must be some obvious way to do this, but the proximity of the weekend is interfering with my higher brain functions.

  • Dictionary with delegate or swith?

    - by Samvel Siradeghyan
    Hi, I am writting a parser, which call some functions dependent on some value. I can implement this logic with simple switch like this swith(some_val) { case 0: func0(); break; case 1: func1(); break; } or with delegates and dictinary like this delegate void some_delegate(); Dictinary some_dictinary = new Dictinary(); some_dictinary[0] = func0; some_dictinary[1] = func1; some_dictinary[some_value].Invoke(); Are this two metods equal and wich is prefered? Thanks.

  • NSIS Installer - Displaying different licences

    - by Wysawyg
    Heya, I'm trying to modify an existing NSIS install script to allow for different licence files to be presented to the user depending on whether they are a new or existing user. I have pre-existing code which detects an existing install in the .onInit section. However I'm running into bumps trying to use the NSIS provided licence screen e.g. !InsertMacro MUI_PAGE_LICENSE Content\Licence.rtf I would like to be able to choose between Licence and Licence2.rtf (though they'll be renamed something representative in the final version). I've tried using selectable sections calling functions which nest the !insertmacro but that doesn't work because it needs to be in the base level of the script. I can't change the parameter to be runtime definable because it needs to know what the file is at compile time to build it into the installer. I know I can roll my own custom page called from a function and do it that way but I was wondering if anyone had got the NSIS installer working with using the MUI_PAGE_LICENSE and different licences. Thanks

  • ODP.NET Code Example Critque or best practices

    - by andrewWinn
    I currently have a DataAccess Layer in Vb.Net. I am not too happy with my implementation of both my ExecuteQuery (as DataSet) and ExecuteNonQuery functions. Does anyone have any code that I could see? My code just doesn't look clean. Any thoughts or critiques on it would be appreciated also. Using odpConn As OracleConnection = New OracleConnection(_myConnString) odpConn.Open() If _beginTransaction Then txn = odpConn.BeginTransaction(IsolationLevel.Serializable) End If Try Using odpCmd As OracleCommand = odpConn.CreateCommand() odpCmd.CommandType = CommandType.Text odpCmd.CommandText = sSql For i = 0 To parameters.Parameters.Count - 1 Dim prm As New OracleParameter prm = DirectCast(parameters.Parameters(i), ICloneable).Clone odpCmd.Parameters.Add(prm) Next If (odpConn.State = ConnectionState.Closed) Then odpConn.Open() End If iToReturn = odpCmd.ExecuteNonQuery() If _beginTransaction Then txn.Commit() End If End Using Catch txn.Rollback() End Try End Using

  • Is it naughty to have a large utility file?

    - by banister
    In my C project I have quite a large utils.c file. It is really full of many utilities of different sorts. I feel a bit naughty just stuffing different miscellaneous functions in there. For example it has some utilities related to low level stuff such as a lowercase() function, and it also has some quite sophisticated utilities such as converting to/from different colour formats. My question is, is it very naughty to have such a large utils.c with many different types of utilities in it? Should I break it up into many different kinds of utility files? Such as graphics_utils.c and so on What do you think?

  • Wordpress "Home" link

    - by Johann
    Hi all, I'm working on a Sandbox based Wordpress theme and I would like to add a home link as a first item in the navigation. I know I should change the function in "sandbox_globalnav" in the functions.php file, which is: // Produces a list of pages in the header without whitespace function sandbox_globalnav() { if ( $menu = str_replace( array( "\r", "\n", "\t" ), '', wp_list_pages('title_li=&sort_column=menu_order&echo=0') ) ) $menu = '<ul>' . $menu . '</ul>'; $menu = '<div id="menu">' . $menu . "</div>\n"; echo apply_filters( 'globalnav_menu', $menu ); // Filter to override default globalnav: globalnav_menu } However, my PHP skills are really basic and I'm not sure where I should override this. Thanks!

  • load/unload C dll with C# problems

    - by Goran
    I'm having problems with external native DLL. I'm working on ASP.NET 1.1 web application and have this DLL which I load through DLLImport directives. This is how I map DLL functions: [DllImport("somedllname", CallingConvention=CallingConvention.StdCall)] public static extern int function1(string lpFileName,string lpOwnerPw,string lpUserPw); [DllImport("somedllname", CallingConvention=CallingConvention.StdCall)] public static extern int function2(int nHandle); I call the dll methods and all works great, but I have problems with this DLL crashing my web site on some cases, so I would like an option to unload the dll after I use it. I found a solution at this link, but I don't have 'UnmanagedFunctionPointer' attribute in .NET 1.1 available. http://blogs.msdn.com/jonathanswift/archive/2006/10/03/Dynamically-calling-an-unmanaged-dll-from-.NET-_2800_C_23002900_.aspx Is there a way I can achieve what this guy did with his example?

  • Thoughts on a Shoutbox anyone?

    - by sologhost
    I'm wanting to create a shoutbox, though I'm wondering if there is another way to go about this rather than using setInterval to query the database for new shouts every number of seconds. Honestly, I don't like having to go about it this way. Seems a bit redundant and repetitive and just plain old wrong. Not to mention the blinking of the shouts as it grabs the data. So I'm wondering on how the professionals do this? I mean, I've seen shoutboxes that work surperb and doesn't seem to be using any setInterval or setTimeout javascript functions to do this. Can anyone suggest any ideas or an approach to this that doesn't use setInterval or setTimeout?? Thanks :)

  • Is there a code style enforcer?

    - by Petruza
    I'm working with websites written in PHP, along with many other programmers, and sometimes I have to deal with really awful code. Indentation totally messed up, curly braces in the wrong places, terrible whitespace use, it really hurts my eyes and actually makes my work harder and take longer. Is there a tool where you can specify your coding style and then it applies it to files? I'm sure there must be such functions in different IDEs, but I need an independent tool as I code with simple notepads like Notepad++ or the like. ( if it's such a function in Notepad++, I didn't see it )

  • jQuery AJAX not redirecting?

    - by MidnightLightning
    I have a simple PHP page (for testing) that simply calls header("Location: http://www.example.com");exit;, which resides on the same server, in the same directory as another file with the following jQuery Javascript: $(document).ready(function() { jQuery.ajax({ type : 'GET', url : 'bounce.php', error : function(xhr, status, error) { console.log("ERROR: ", xhr, xhr.status, xhr.getAllResponseHeaders()); }, complete : function(xhr, status) { // Get headers of the response console.log("COMPLETE: ", xhr, xhr.status, xhr.getAllResponseHeaders()); } }); }); I was expecting (from several other StackOverflow responses) for the xhr.status to return "302", but instead the AJAX call is triggering the "error" event (and then the "complete" event), and xhr.status is returning 0 (zero), and .getAllResponseHeaders() is coming back null (in both the error, and complete functions). Firebug is showing the "302 Moved Temporarily", and the response headers. So why is this triggering the error event, and not passing along the proper 302 code, and headers? Is this something to do with the Same Origin since the bouncing script and the fetching script are both on the same server? Is this jQuery or Javascript's fault?
