  • Actionscript 3.0 Get all instances of a class?

    - by Windbrand
    I got a ton of movieclips in a class. Is there a more efficient way to apply a function to every instance in the class other than this? var textArray:Array = [ interludes.interludeIntro.interludeBegin1, interludes.interludeIntro.interludeBegin2, interludes.interludeIntro.interludeBegin3, interludes.interludeIntro.interludeBegin4, interludes.interludeIntro.interludeBegin5, interludes.interludeIntro.interludeBegin6, interludes.interludeIntro.interludeBegin7, //... ... ... interludes.interludeIntro.interludeBegin15 ]; for each (var interludeText:MovieClip in interludeBeginText) { interludeText.alpha = 0 //clear all text first } Also for some reason this doesn't work: interludes.interludeIntro.alpha = 0; It permanently turns that class invisible, even if I try to make specific instances visible later with: interludes.interludeIntro.interludeBegin1.alpha = 1; I have NO idea why the above doesn't work. I want to turn every single instance in the class interludeIntro invisible, but I want to turn specific instances visible later. (btw I have no idea how to insert code on this website, pressing "code" doesn't do anything, so pardon the bad formatting)

  • How can I optimize this code?

    - by loop0
    Hi, I'm developing a logger daemon to squid to grab the logs on a mongodb database. But I'm experiencing too much cpu utilization. How can I optimize this code? from sys import stdin from pymongo import Connection connection = Connection() db = connection.squid logs = db.logs buffer = [] a = 'timestamp' b = 'resp_time' c = 'src_ip' d = 'cache_status' e = 'reply_size' f = 'req_method' g = 'req_url' h = 'username' i = 'dst_ip' j = 'mime_type' L = 'L' while True: l = stdin.readline() if l[0] == L: l = l[1:].split() buffer.append({ a: float(l[0]), b: int(l[1]), c: l[2], d: l[3], e: int(l[4]), f: l[5], g: l[6], h: l[7], i: l[8], j: l[9] } ) if len(buffer) == 1000: logs.insert(buffer) buffer = [] if not l: break connection.disconnect()

  • C++ Reference of vector

    - by void
    Hello, class Refvect { public: vector<int> &refv; Refvect(int t, vector<int> &refv = vector<int>()) : refv(refv) { }; void operator()() { refv.clear(); } }; int main () { Refvect r(0); r(); } With Visual Studio 2010, this gives me an error : "vector iterators incompatible" at the execution, but I don't understand why (but I can insert elements in refv without any problem). The temporary object vector() lives as long as the reference, no?

  • NHibernate - Is ITransaction.Commit really necessary?

    - by user365383
    Hi I've just start studying NHibernate 2 days ago, and i'm looking for a CRUD method that i've writed based on an tutorial. My insert method is: using (ISession session = Contexto.OpenSession()) using (ITransaction transaction = session.BeginTransaction()) { session.Save(noticia); transaction.Commit(); session.Close(); } The complete code of "Contexto" is here: http://codepaste.net/mrnoo5 My question is: Do i really need to use ITransaction transaction = session.BeginTransaction() and transaction.Commit();? I'm asking this because i've tested run the web app without those two lines, and i've sucefully inserted new records. If possible, can someone explain me too the porpuse of Itransaction and the method Commit? Thanks

  • Question about inserting/updating rows with MS SQL (ASP.NET MVC)

    - by Alex
    I have a very big table with a lot of rows, every row has stats for every user for certain days. And obviously I don't have any stats for future. So to update the stats I use UPDATE Stats SET Visits=@val WHERE ... a lot of conditions ... AND Date=@Today But what if the row doesn't exist? I'd have to use INSERT INTO Stats (...) VALUES (Visits=@val, ..., Date=@Today) How can I check if the row exists or not? Is there any way different from doing the COUNT(*)? If I fill the table with empty cells, it'd take hundreds of thousands of rows taking megabytes and storing no data.

  • Python: What's a correct and good way to implement __hash__()?

    - by random-name
    What's a correct and good way to implement hash()? I am talking about the function that returns a hashcode that is then used to insert objects into hashtables aka dictionaries. As hash() returns an integer and is used for "binning" objects into hashtables I assume that the values of the returned integer should be uniformly distributed for common data (to minimize collisions). What's a good practice to get such values? Are collisions a problem? In my case I have a small class which acts as a container class holding some ints, some floats and a string.

  • The data structure of libev watchers

    - by changchang
    Libev uses three data structures to storage different watchers. Heap: for watchers that sorted by time, such as ev_timer and ev_periodic. Linked list: such as ev_io, ev_signal, ev_child and etc. Array: such as ev_prepare, ev_check, ev_async and etc. There is no doubt about that uses heap to store timer watcher. But what is the criteria of selecting linked list and array? The data structure that stores ev_io watchers seems a little complex. It first is an array that with fd as its index and the element in the array is a linked list of ev_io watcher. It is more convenient to allocate space for array if use linked list as element. Is it the reason? Or just because of the insert or remove operation of ev_io is more frequently and the ev_prepare seems more stable? Or any other reasons?

  • Serialize object from within

    - by Maximus
    I have the class testClass which has the method save. This method saves object to a database. But it needs to serialize object before saving. How can I serialize object from within the class to do that? class testClass { private $prop = 777; public function save() { $serializedObject = serialize(self); DB::insert('objects', array('id', 'object')) ->values(array(1, $serializedObject)) ->execute(); } } serialize(self) obviously doesn't work.

  • A little javascript help needed here (easy).

    - by Camran
    function addOption(selectbox, val, txt){ ...... } addOption(list, "Cars", "Cars"); I need to add this in front of the text of the function: &nbsp;&nbsp;&nbsp; So that there is space coming in before the option text...Never mind what it is for, it is just confusing... I just don't know how to insert it into the js code. If I do it like this: addOption(list, "Cars", "&nbsp;&nbsp;&nbsp;Cars"); Then the &nbsp;&nbsp;&nbsp; comes into the text, so it gets displayed for the users. However I need it to be interpreted as "space"... If you don't understand let me know... How can I do this? Quotes, double quotes etc? Thanks

  • PHP 1-liner each() with mysql_fetch_assoc()

    - by MVC You Know Me
    Hey All. Trying to create a 1-liner to loop through a mysql result set. Example: $sql = "SELECT uid, role FROM usr WHERE uid = '$this-uid'"; $r = db::q($sql); if($r-rows()) { $q = mysql_fetch_assoc($r-result); while(list($k, $v) = each($q)) { // would like to omit line above and consolidate here $_SESSION['usr'][$k] = $this->$k = $v; } } problem is that consolidating while loop like so: while(list($k, $v) = each(mysql_fetch_assoc($r-result)) returns an error a la each() not getting object or array, even though of course it is. I think the problem is a casting issue, but it does not seem you can do: each( (array) mysql_fetch_assoc($r-result)) Any ideas? I like to code as tersely as possible, and having "$q = mysql_fetch_assoc($r-result)" everywhere will annoy me, does already. Keep posted... Thanks!

  • SQL: Optimize insensive SELECTs on DateTime fields

    - by Fedyashev Nikita
    I have an application for scheduling certain events. And all these events must be reviewed after each scheduled time. So basically we have 3 tables: items(id, name) scheduled_items(id, item_id, execute_at - datetime) - item_id column has an index option. reviewed_items(id, item_id, created_at - datetime) - item_id column has an index option. So core function of the application is "give me any items(which are not yet reviewed) for the actual moment". How can I optimize this solution for speed(because it is very core business feature and not micro optimization)? I suppose that adding index to the datetime fields doesn't make any sense because the cardinality or uniqueness on that fields are very high and index won't give any(?) speed-up. Is it correct? What would you recommend? Should I try no-SQL? -- mysql -V 5.075 I use caching where it makes sence.

  • Becoming better at Vim

    - by Autopulated
    I've been using Vim for quite a long time, but I'm at a level where I use insert mode most of the time, and I still use the arrow keys to move around(!). I feel like I'm not getting the best out of my lovely editor, particularly regarding navigating (especially code), copy & pasting, and doing other manipulations of existing code. (though I am quite comfortable with complicated search/replace patterns). How should I go about learning more? What resources would people recommend?

  • how to make struct member pointer in assembly?

    - by sillis
    I`m trying to create a macro which would make easier to point to a structs member. Currently i am pointing to a structs member in assembly file using the STRUCT_NAME + offset method. For example if i want to point structs third member,i would have to do it like this: STRUCT_NAME + 3. This seems stupid way to do it, and if i insert more members in the struct, i have to update all the offset values in the code. Is there a way to point using STRUCT_NAME + macro(struct_name, member_name) ? I`m using texas instruments TMS320C28x hardware. Thanks!

  • Secure method for linking to image files uploaded via custom CMS

    - by letseatfood
    How does one provide a direct URL for an image file (JPEG) that is secure? For example, if a PHP script writes uploaded images to directory http://www.somehost.com/images, is it okay to provide http://www.somehost.com/images/someimage.jpg as the URL, or is there a more secure way to do this? Should I look into something like the permalink feature that is a part of Wordpress? I am not sure if that is related. The main reason I ask is that I have a custom PHP/MySQL CMS for managing images. I would like for the client to be able to copy a link to the image they want and then include it in a TinyMCE text editor for inserting the image in their website. Thanks!

  • ORACLE and TRIGGERS (inserted, updated, deleted)

    - by vandalo
    Hello, I would like to use a trigger on table which will be fired every time a row is inserted, updated, deleted. I wrote something like this: CREATE or REPLACE TRIGGER test001 AFTER INSERT OR DELETE OR UPDATE ON tabletest001 REFERENCING OLD AS old_buffer NEW AS new_buffer FOR EACH ROW WHEN (new_buffer.field1 = 'HBP00') and it works. Since I would like to do the same things if the row is inserted, updated or deleted I would like to know what's happening in the trigger. I think I can manage to find if the row in inserted or updated (I can check the old_buffer with the new_buffer). How can I know if the row has been deleted? Alberto

  • How does make_pair know the types of its args?

    - by bobobobo
    The definition for make_pair in the MSVC++ "utility" header is: template<class _Ty1, class _Ty2> inline pair<_Ty1, _Ty2> make_pair(_Ty1 _Val1, _Ty2 _Val2) { // return pair composed from arguments return (pair<_Ty1, _Ty2>(_Val1, _Val2)); } I use make_pair all the time though without putting the argument types in angle brackets: map<string,int> theMap ; theMap.insert( make_pair( "string", 5 ) ) ; Shouldn't I have to tell make_pair that the first argument is std::string and not char* ? How does it know?
