i'm trying code class binary tree representation. each node has value ( key ), index , , node* pointer parent( p ), left-child( left ) , right-child( right ). problem on pointers. it's easier giving example problem explaining. i coded print() function prints out each node in tree. here class header file. , here main test file. the problem is, when call t.print() , prints 10, 5 , 7. the problem you're using vector , internally (re-)allocates storage needed. so, when pushing vector, whole internal data copied other memory location - making pointers still point old locations invalid. an easy "fix" reserve amount of space vector, can @ least store amount of nodes in without re-allocation. for example adding @ start of rootedtree constructors : t.reserve(64); note that not robust solution (if try put more 64 nodes in vector, you're still have same problem) - it'll confirm above analysis.

i'm using hibernate , db sqlserver. sql server differentiates it's data types support unicode ones support ascii. example, character data types support unicode nchar, nvarchar, longnvarchar ascii counter parts char, varchar , longvarchar respectively. default, microsoft’s jdbc drivers send strings in unicode format sql server, irrespective of whether datatype of corresponding column defined in sql server supports unicode or not. in case data types of columns support unicode, smooth. but, in cases data types of columns not support unicode, serious performance issues arise during data fetches. sql server tries convert non-unicode datatypes in table unicode datatypes before doing comparison. moreover, if index exists on non-unicode column, ignored. lead whole table scan during data fetch, thereby slowing down search queries drastically. the solution used ,we figured there property called sendstringparametersasunicode helps in getting rid of unicode conversion. property defa...

i need create screen scrolls vertically - tableview need 3 columns , within 3 columns need add images of varying height - not fit rows tableview can provide. should create 3 tableviews , lay them out side side - or else. think build positioning images using coordinates wanted benefit methods table view can provide. if want columns act stuck together, scroll simultaneously, think best approach use uiscrollview images added in correct placed "by hand." uitableview , friends not built handle non-lined columns. added if use uiscrollview , , have large number of images want display (that is, user can scroll long time), wise recycle uiimageview objects scrolled off screen. uitableview uitableviewcell objects, , that's why uitableview wins. can win, too, if code carefully.

i using mongod database rails 3 how execute similar code following sql in mongod. there way execute group , sort in mongod select a,b,sum(c) csum coll active=1 group a,b order thanks inspired example on mongo's website. generate dummy data: > db.stack.insert({a:1,b:1,c:1,active:1}) > db.stack.insert({a:1,b:1,c:2,active:0}) > db.stack.insert({a:1,b:2,c:3,active:1}) > db.stack.insert({a:1,b:2,c:2,active:0}) > db.stack.insert({a:2,b:1,c:3,active:1}) > db.stack.insert({a:2,b:1,c:10,active:1}) > db.stack.insert({a:2,b:2,c:10,active:0}) > db.stack.insert({a:2,b:2,c:5,active:1}) mongo query: > db.stack.aggregate( ... {$match:{active:1}}, ... {$group:{_id:{a:"$a", b:"$b"}, csum:{$sum:"$c"}}}, ... {$sort:{"_id.a":1}}) result: {"result" : [ {"_id" : {"a" : 1,"b" : 2},"csum" : 3}, {"_id" : {"a" : 1,"b" : 1},...

i'm in middle of writing android app, , i'd externalise of features external service. either use existing hosting, , write simple php web services, or little more involved- (which have th advantage of me not having learn php). ideally, i'd write web services in java because i'm comfortable writing , securing them. i'm wondering whether sensible use of ec2, , if so, ami best use? any appreciated. if you're looking @ java web service , you'd scale aws's elastic beanstalk amazon's turnkey solution. takes care of automatically scaling app demand grows , shrinks. http://aws.amazon.com/elasticbeanstalk/

so here want do. the first option write each function in different php file each 1 , include of them in php file called include functions.php , whenever create new page , let's index.php include "functions.php"; why need that? because i'll have include 1 file , functions included. problem server load. i'm not sure how uncalled functions affect performance. the second option create again files need, team them , whenever need function call it. drawback of i'll have more work in order categorize , i'll have include lot of files so want ask, first option increase cpu , memory load have go second one? there performance issues first way or functions not being used not parsed @ php ? disk slowest part of server, in case variant "all functions in 1 file" give little more performance, theoretically. but don't recommend create "functions.php", better way oop . create classes (objects) methods, use autoloaders , psr...

i have several backup files in location, c:\backup_folder\... need batch script ( .bat ), files under c:\backup_folder\*.zip moved particular ftp location ( ftp.mysite.com ). also, if file exists on ftp site, must overwritten new file... can show me script performs these backups? the trick automated file xfer windows (for me @ least) has been using correct commandline upload tool. me, when i've wanted shell-scriptable tool, ends being rsync cygwin. since asked windows batch ftp (as opposed safer, more reliable solution, might want try using windows build of wput since want overwrite file each time, use -u (re-upload) option. found wput supported of ftp options wanted, , should handle job. although absolutely agree desire re-upload entire file, can set few optimizations might find handy if you're uploading on slow link, using timestamp comparison decide if don't need upload (-n). option backup scripts may want remove source file after successful uploa...

i have functions , xml file in store name of functions , components..eg. <commands> <command> <flexobject>myobject1</flexobject> <flexfunction>myfunction1</flexfunction> </command> <command> <flexobject>myobject2</flexobject> <flexfunction>myfunction2</flexfunction> </command> </commands> i want make array of functions , call them..like as arr:array = new array(); arr.push(myobject1.myfunction1); arr.push(myobject2.myfunction1); arr[0](); call myobject1.myfunction1 function myobjects , myfunctions classic component , functions when call setcommandsservice.send <s:httpservice id="setcommandsservice" url="commands.xml" result="setcommandsservice_resulthandler(event)"/> in handler name of function string , dont know how can add array function.. okay, need make sure objects , functions there, should possible using dyna...

i have tried <?php print_r(apache_get_modules()); ?> and got fatal error: call undefined function apache_get_modules() in why error built in function , how list of modules the manual page contains details php , apache version support apache_get_modules() . you must running php >= 4.3.2 , using apache 2 handler api, or php >= 5.0 , apache 1 or apache 2 filter api.

i have following code confuse me now, hope can tell me difference , how fix this. (defmacro tm(a) `(concat ,(symbol-name a))) (defun tf(a) (list (quote concat) (symbol-name a))) i think should same effect, seem not. try following call: cl-user> (tf 'foo) (concat "foo") cl-user> (tm 'foo) value 'foo not of expected type symbol. [condition of type type-error] so, what's problem? what want is: (tm 'foo) ==> (concat "foo") first, note that `(concat ,(symbol-name a)) and (list (quote concat) (symbol-name a)) do exact same thing. equivalent pieces of code (backquote syntax isn't restricted macro bodies!): both construct list first element symbol concat , second element symbol name of whatever variable a refers to. clearly, makes sense if a refers symbol, which, svante has pointed out, isn't case in macro call example. you could , of course, extract symbol list (quote foo) , preven...

alright, exercise: define class named student, containing 3 grades of students. class have function calculates grades average. now, define class named student1 derived student , add function calculate sum of grades.in main program, define student variable , object of type student1. perform placement of object variable , run function of student1. note: not homework, i'm learning own. code: class student { protected int grade1, grade2, grade3; public student(int grade1, int grade2, int grade3) { this.grade1 = grade1; this.grade2 = grade2; this.grade3 = grade3; } public double average() { return (grade1 + grade2 + grade3) / 3; } } class student1 : student { public student1(int grade1, int grade2, int grade3) : base(grade1, grade2, grade3) { } public double sum() { return grade1 + grade2 + grade3; } } class program { static void main(string[] args)...

in database there record include razor syntax "hello @model.name, wellcome ..." when record view how can render model property ? thanks, there many ways. pulling view database rather file http://razorengine.codeplex.com http://ibashir.blogspot.com/2010/11/razor-parser-without-mvc.html http://blog.andrewnurse.net/2010/07/22/usingtherazorparseroutsideofaspnet.aspx i'm biased towards razorengine codeplex it's been used in mini-profiler developers of site.

in c++03 can use const& trick (or "most important const") extend lifetime of temporary lifetime of reference. question is, in c++0x, behaviour extend rvalue references? i.e auto&& x = somefunction(); according [class.temporary] , if compiles yes, lifetime of temporary extended.
