  • Adobe After Efects Plugin With Cocoa (Overriding malloc)

    - by mustISignUp
    Messing about a bit, i have a working Adobe After Effects plugin with a bit of Obj-c / Cocoa in it (NSArray and custom objects - not ui stuff). The SDK guide states:- Always use After Effects memory allocation functions. In low-memory conditions (such as during RAM preview), it’s very important that plug-ins not compete with After Effects for OS memory, and deal gracefully with out-of-memory conditions. Failing to use our functions can cause lock-ups, crashes, and tech support calls. Don’t do that. If you’re wrapping existing C++ code, overloading new and delete to use our functions will save substantial reimplementation. On Windows, derive all classes from a common base class which implements new and delete. so my question.. is something compatible with the above statement possible in Obj-c?

  • Why doesn't the C++ default destructor destroy my objects?

    - by Oszkar
    The C++ specification says the default destructor deletes all non-static members. Nevertheless, I can't manage to achieve that. I have this: class N { public: ~N() { std::cout << "Destroying object of type N"; } }; class M { public: M() { n = new N; } // ~M() { //this should happen by default // delete n; // } private: N* n; }; Then this should print the given message, but it doesn't: M* m = new M(); delete m; //this should invoke the default destructor

  • Batch & log files

    - by Mat
    Hi All, Please help!!! ;) I have a problem with this code in a batch file (Linux): Mil=`date +"%Y%m%d%H%M%S"` batch=`echo "${DatMusic}"` TabimportEnteteMusic="importentetemusic.dat" { grep '^ENTETE' ${IMPORT}/${DatMusic} > ${IMPORT}/$TabimportEnteteMusic mysql -u basemine --password="basemine" -D basemine -e "delete from importmusic;" mysql -u basemine --password="basemine" -D basemine -e "delete from importentetemusic;" } >> $TRACES/batch/$Mil.$batch.log 2>&1 When I run this batch, its answer is: /home/mmoine/sgbd_mysql/batch/importMusic.sh: line 51: /batch/20100319160018.afce01aa.cr.log: Aucun fichier ou répertoire de ce type (in english, I suppose: "No files or Directory found") So, please, how can I put all generated messages in this log file? Thanks for your answers. Sorry for my english ;)

  • update_attributes with validations

    - by Timothy
    I have the following contrived example in Rails. I want to make sure the Garage model has at least one car with this. class Garage has_many :cars validate :at_least_one_car def at_least_one_car if cars.count == 0 errors.add_to_base("needs at least one car") end end end class Car belongs_to :garage end In my form I have a remove button that will set the hidden field _delete to true for an existing car. Let's say there is only one car object and I "delete" it in my form, if I do garage_object.update_attributes(params[:garage]), it will delete the car model and make the garage object invalid. Is there to a way to make it not update the attributes if it will make the model invalid?

  • error in c, but not in c++

    - by eswar
    const int t=5; char buf[t+5]; When I compile this gives error in C but not in C++!! Can anybody please explain me the reason? Note: I know the const defaults to internal linkage in 'C++', where as in 'C' it defaults to external linkage. Does it has any relation to the above case??

  • Deadlock Problem because of an Update Lock.

    - by Randy Minder
    We have a deadlock issue we're trying to track down. I have an deadlock graph (xdl) generated from Profiler. It shows the losing SQL statement as a simple Select statement, not an Update, Delete or Insert statement. The graph shows the losing Select statement as requesting a Shared lock on a resource **but also owning an Update lock on a resource**. This is what is baffling me. Why would a Select statement that is not part of an Insert, Update or Delete ever hold an Update lock on a resource? I should add that the Update lock it owns is on the table being selected against by the losing Select statement.

  • link_to syntax with rails3 (link_to_remote) and basic javascript not working in a rails3 app?

    - by z3cko
    i am wondering if the basic link_to syntax is completely broken in current rails3 master or if i am doing some wrong syntax here. = link_to "name", nil, :onlick => "alert('Hello world!');" should actually produce an alert on click. very simple. does not work on my rails3 project! (also no error output!) any ideas? for the general link_to syntax i could not find an example where i could combine a link_to_remote with a confirmation, remote and html class (see my try below) = link_to "delete", {:action => "destroy", :remote => true, :method => :delete, :confirm => "#{a.title} wirklich L&ouml;schen?" }, :class => "trash" even the rails3 api does not help me here: http://rails3api.s3.amazonaws.com/index.html help!

  • Why does my ConfirmButtonExtender cause full postbacks after I've toggled its parent usercontrol's v

    - by zk812
    Hello all, I have a series of usercontrols on a page that are displayed based on a selection. Each usercontrol contains a Delete button with a ConfirmButton/ModalPopupExtender combo attached to it. This works great when first loading any of the usercontrols--clicking delete shows my Confirm Modal popup and hitting yes or no causes an async postback to perform the operation. But if I move away from the usercontrol and come back to it, the Confirm Modal Popup appears but clicking yes or no now causes a full postback (the operation does still take place). Why does changing the visible property cause this?

  • Get Absolute Position of element within the window in wpf

    - by BrandonS
    I would like to get the absolute position of an element in relation to the window/root element when it is double clicked. The element's relative position within it's parent is all I can seem to get to, and what I'm trying to get to is the point relative to the window. I've seen solutions of how to get a the point of an element on the screen, but not in the window.

  • Actionscript flex: Converting # colors to uint

    - by Daryl
    I'm working with several components that take color as a uint, but the colors I have are in the format of "#161616". I'm not sure what the relation between the 2 types of colors are or how to go from one to another. It doesn't have to be an actionscript solution. I have only a small number of these colors, so can be done manually too.

  • Codeigniter: How to handle direct link to controller/function/param?

    - by rebjr
    I have a simple controller function which deletes a DB entry (it uses a model function to do so). I have a link to this in one of my views (e.g. http://www.example.com/item/delete/3) and I’m using jQuery to display a confirm dialog to make sure the user really wants to delete it. All fine. However if you just enter that URL in your browser the item is deleted without warning. Is there a way to handle this either in the way I code the controller function or in the model?

  • C++: How to require that one template type is derived from the other

    - by Will
    In a comparison operator: template<class R1, class R2> bool operator==(Manager<R1> m1, Manager<R2> m2) { return m1.internal_field == m2.internal_field; } Is there any way I could enforce that R1 and R2 must have a supertype or subtype relation? That is, I'd like to allow either R1 to be derived from R2, or R2 to be derived from R1, but disallow the comparison if R1 and R2 are unrelated types.

  • why does InnoDB keep on growing without for every update?

    - by Akash Kava
    I have a table which consists of heavy blobs, and I wanted to conduct some tests on it. I know deleted space is not reclaimed by innodb, so I decided to reuse existing records by updating its own values instead of createing new records. But I noticed, whether I delete and insert a new entry, or I do UPDATE on existing ROW, InnoDB keeps on growing. Assuming I have 100 Rows, each Storing 500KB of information, My InnoDB size is 10MB, now when I call UPDATE on all rows (no insert/ no delete), the innodb grows by ~8MB for every run I do. All I am doing is I am storing exactly 500KB of data in each row, with little modification, and size of blob is fixed. What can I do to prevent this? I know about optimize table, but I cant do it because on regular usage, the table is going to be 60-100GB big, and running optimize will just stall entire server.

  • What does -setPropagatesDeletesAtEndOfEvent: actually do?

    - by dontWatchMyProfile
    Let me try it: If I don't set this, then the default value is YES. So when I delete an managed object from the context, the context propagates this immediately to the persistent store so the object is gone? And when I set this to NO, then objects are deleted from the persistent store only when calling -save? Is that really true? I mean: If it was true, then the default behavior is that once you call the context to delete an object, the object is gone. Lets assume you're not using an undo manager. So... gone. Right? No rollback possible? Or can it still be recovered with a rollback?

  • mysql codeigniter active record m:m deletion

    - by sea_1987
    Hi There, I have a table 2 tables that have a m:m relationship, what I can wanting is that when I delete a row from one of the tables I want the row in the joining table to be deleted as well, my sql is as follow, Table 1 CREATE TABLE IF NOT EXISTS `job_feed` ( `id` int(11) NOT NULL AUTO_INCREMENT, `body` text NOT NULL, `date_posted` int(10) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=3 ; Table 2 CREATE TABLE IF NOT EXISTS `job_feed_has_employer_details` ( `job_feed_id` int(11) NOT NULL, `employer_details_id` int(11) NOT NULL, PRIMARY KEY (`job_feed_id`,`employer_details_id`), KEY `fk_job_feed_has_employer_details_job_feed1` (`job_feed_id`), KEY `fk_job_feed_has_employer_details_employer_details1` (`employer_details_id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; So what I am wanting to do is, if the a row is deleted from table1 and has an id of 1 I want the row in table to that also has that idea as part of the relationship also. I want to do this in keeping with codeigniters active record class I currently have this, public function deleteJobFeed($feed_id) { $this->db->where('id', $feed_id) ->delete('job_feed'); return $feed_id; }

  • mysql row counter

    - by David19801
    Hello, I have a mysql table. It has auto increment on the id. but I regularly delete rows so the numbers are all over the place. I need to get the last n rows out, but because of deletions, the common way of using the max of the autoincremented id column doesn't work well... 1 - Is their another way to get the bottom 50? 2 - Is their a way to get rows by actual row number? so if I have 4 rows labelled 1,2,3,4 delete row 2 then it will become 1,2,3 rather than 1,3,4?
