i have 2 objects: public class program { [key] [databasegenerated(databasegeneratedoption.identity)] public long id { get; set; } public string name { get; set; } public virtual icollection<videofile> files { get; set; } } public class videofile { [key] [databasegenerated(databasegeneratedoption.identity)] public long id { get; set; } [required] public string path { get; set; } [required] public virtual program program { get; set; } } the 2 tables correctly created in database, when save program insert files childs too, when tried program file collection come nulls, have lazyload enable, , default entity framework return empty collection when child collection empty why have null?

i using cocos2d , have following code moves layer based on player touching screen. reason, each time code called position of layer shifts 32 in 1 direction or other. cant fathom why happening. there no other code anywhere in program manipulates position of these ccnodes (or other node). -(void) animatestructure:(int)index and:(ccsprite*)asprite at:(cgpoint)apoint { cgpoint point1 = self.position; cgpoint point2 = playersprite.position; id move = [ccmoveby actionwithduration:0.1 position:ccp(32*tempx,32*tempy)]; [self runaction:move]; id move2 = [ccmoveby actionwithduration:0.1 position:ccp(-32*tempx,-32*tempy)]; [playersprite runaction:move2]; self.position = point1; playersprite.position = point2; } not how move actions play-out if set position while action in progress, case here.

i'm working on rewriting aging web applications. there 2 in particular very, similar, yet share no code today , aim fix that. the projects being rewritten maven, spring mvc, , sitemesh. model tier code easy enough share using jars. don't know of ways share common web-tier code (jsps , controllers) between similar apps. here's background. these apps webstores. 1 normal store (think amazon.com) user can sign into, search products, add shopping cart, , check out. other same thing, it's punchout site. product browse , shopping cart portions identical. sign in , checkout, however, different. i'm oversimplifying, it's enough illustrate problem. there's significant portion of web-tier code in product browse , shopping cart sections should able shared between two. i don't think it's possible have same war file running either "mode" based on environment variable or settings different database. 1 of differences different sprin

i have got problem phpexcel below function function test($a, $b) { // create new phpexcel object single sheet $objphpexcel = new phpexcel(); $activesheet = $objphpexcel->getactivesheet(); $activesheet->setcellvalue('b2',$a); $activesheet->setcellvalue('b3',$b); $activesheet->setcellvalue('c4',"=b2+b3"); $c4 = $activesheet ->getcell('c4')->getcalculatedvalue(); echo "c4:$c4<br/>"; } finally, call function test(10, 20); test(40, 70); test(30, 80); but, result is c4:30 c4:30 c4:30 why getcalculatedvalue() doesn't change result? seems function gets first value. you can change result, performance reasons calculation engine caches result of formula calculation once it's been calculated. if want change underlying data, have flush cache before requesting calculated value again: phpexcel_calculation::getinstance()->clearcalculationcache(); or

i iterating on data dynamically. data contains 3 fields want insert array.. array(field1,field2,field3)..and insert array array (nest it). nest array main array. problem dont know how 1 array out of loop contain nested arrays. $myarray=array(); while($row=mysql_fetch_array($result)) { $myarray+= array(field1,field2,field3); } how add them dynamically..i know wrong way..but how do it?! while ($row = mysql_fetch_assoc($result1) { $myarray[] = array($row['field1'], $row['field2'], $row['field3']); } if want add whole content of each row, i.e. every field in row, can use while ($row = mysql_fetch_assoc($result1) { $myarray[] = $row; } or single line: while ($myarray[] = mysql_fetch_assoc($result)); then can access e.g. field2 of row 5 $myarray[4]['field2'] in question use function mysql_fetch_array. please use mysql_fetch_assoc better way. mysql_fetch_array returns every value twice, once numeric index

i preparing release app using device google account authenticate on google app engine server. to that, need permissions : use_credentials : obviously internet : obviously get_accounts : ask user select 1 of google accounts registered on phone. my problem get_accounts : think it's quite intrusive ask permission along internet : able accounts (google, facebook, etc...) , send them server (i won't of course !). fear permission may scare users, , may not download app... i had idea report permission other app, wouldn't have internet permission. app called intent, , return account chosen user. , then, main app don't need get_accounts anymore. the source code there : http://code.google.com/p/account-chooser/ it's quite simple (only 1 screen) to send intent app use utility library intentintegrator zxing. if "account chooser" app not present on device, asks user download market. what think ? idea ? right bother user downloading mysterious app

i noticing differences between hash object within ruby 1.8.7 , hash object within rails 3.0.10. for example, within 1.8.7 irb , get: 1.8.7 :001 > {}.try(:method) nomethoderror: undefned method `try' {}:hash (irb):1``` however, 3.0.10 rails console, get: 1.8.7 :003 > {}.try(:method_x) nomethoderror: undefined method `method_x' {}:hash (irb):3:in `try' (irb):3 this surprises me because under impression try defined in object ancestor of hash , try return nil instead of throwing nomethoderror. what missing? this surprises me because under impression try defined in object ancestor of hash , try return nil instead of throwing nomethoderror . what missing? your impression of class try defined in correct ( object ). missing file defined in. it's defined in activesupport library, not in ruby core library. so, need require 'active_support/core_ext/object/try' first.

i'm trying total amount of milliseconds ( not millis field) period object instance. i've tried multiple conversions, couldn't find method giving it. has ever needed , managed retrieve ? (i need patch, figure out negative period; negative millis = negative period.) you can't millis directly period , since fields months , years variable in terms of milliseconds. in order make work, need supply "baseline" instant period can calculate actual millisecond duration. for example, period.todurationfrom , period.todurationto methods take such baseline instant, , calculate duration object, can obtain millis. the javadoc todurationfrom says: gets total millisecond duration of period relative start instant. method adds period specified instant in order calculate duration. an instant must supplied duration of period varies. example, period of 1 month vary between equivalent of 28 , 31 days in milliseconds due different length mont

i hope question appropriate stackoverflow... difference between storing raw data bytes (8 bits) in std::string rather storing them in std::vector<char> . i'm reading binary data file , storing raw bytes in std::string . works well, there no problems or issues doing this. program works expected. however, other programmers prefer std::vector<char> approach , suggest stop using std::string it's unsafe raw bytes. i'm wondering why might unsafe use std::string hold raw data bytes? know std::string used store ascii text, byte byte, don't understand preference of std::vector<char> . thanks advice! the problem not whether works or doesn't. problem is utterly confusing next guy reading code. std::string meant displaying text. reading code expect that. you'll declare intent better std::vector<char> . it increases wtf/min in code reviews.

why can't use both return , yield return in same method? for example, can have getintegers1 , getintegers2 below, not getintegers3. public ienumerable<int> getintegers1() { return new[] { 4, 5, 6 }; } public ienumerable<int> getintegers2() { yield return 1; yield return 2; yield return 3; } public ienumerable<int> getintegers3() { if ( somecondition ) { return new[] {4, 5, 6}; // compiler error } else { yield return 1; yield return 2; yield return 3; } } return eager. returns entire resultset @ once. yield return builds enumerator. behind scenes c# compiler emits necessary class enumerator when use yield return . compiler doesn't runtime conditions such if ( somecondition ) when determining whether should emit code enumerable or have method returns simple array. detects in method using both not possible cannot emit code enumerator , @ same time have method return normal array , same method.

(guid)piitem.getvalue(chitem, null) : guid.empty; if (fld.items.select(i => i.itemid).contains(itemid)) { casestoprocess.add(ch); } } toprocess = toprocess.except(casestoprocess, casecomparer).tolist(); } which convert to use linq , lambdas - got close here yesterday this: list<caseheader> toprocess = ....; c

anyone have hints getting clean pdf output proc sgplot (and similar functions sgscatter)? when create graph , write pdf ods, result looks fine in sas eg report window pdf output gets rasterized dpi setting of pdf if zoom pdf can make out pixelation. additionally, if don't define colors/line styles, output in pdf use different colors , styles (lines solid in sas report window become dashed in pdf). if make same chart proc gplot, comes vectorized text , lines don't junk when zoomed/printed. is there option need change? flag need set? i've tried things options device=svg , doesn't seem work. setting high dpi isn't solution either. code example (but really, happens on of sg * functions data/code): options nonumber orientation=landscape; ods pdf file='filename.pdf' notoc; proc sgplot data=shipped; series x=date y=weighted_price / group=type; run; proc gplot data=shipped; plot weighted_price*date=type; symbol1 c=blue i=join v=none

and, how system install gems application without going through bundle install process? note: question process of creating new application . not same question in rails, why there new gemfile.lock when no bundle or bundle install run? (and new gemfile timestamp too) . gemfile.lock snapshot of gems , versions created when run bundle install . explained in checking code version control section of bundler rationale : gemfile.lock makes application single package of both own code , third-party code ran last time know sure worked. specifying exact versions of third-party code depend on in gemfile not provide same guarantee, because gems declare range of versions dependencies. gems can installed outside of bundler rubygems (e.g. gem install gem_name ) it's best use rvm allows install separate versions of ruby , manage individual gemsets each application explained in rvm best practices .

it's ok if have regular format file, this: period end date 09/30/ 06/30/ 03/31/ 12/31/ 09/30/ 2012 2012 2012 2011 2011 then can merge these dates zip or print "%s%s" % (row_1[j], row_2[j]) but have irregular input this: period end date 09/30/2012 06/30/ 03/31/2011 12/31/ 09/30/2012 2011 2010 or this: period end date 09/30/ 06/30/ 03/31/2011 12/31/2011 09/30/2012 2012 2011 so final date merge of row_1 , row2 column, problem how dose python know column is. how should approach this? appreciate much! there lots of ways it, each 1 generalizing different class of inputs-like-this. how about: def dates_from_two(line1, line2): line2 = line2.split() word in line1.split(): wsplit = word.split('/') if len(wsplit) == 3: yield word if wsplit[
