in team still works client tortoisesvn 1.6. tried out 1.7 , find big improvement on windows 7 machine. team members tell me can't upgrade. can't tell me exact reason?! told while ago left company :) is there valid reason stick 1.6? edit beside changed working copy format, benefit of 1.7 higher cost of upgrading of 1.6. the working copy format has changed in 1.7. you'd have upgrade clients use same working copy 1.7 @ once: older clients no longer able access wc once has been upgraded. there may reasons speaking against doing under circumstances (like if [non-tortoise] clients don't have upgraded svn client libraries built in yet). you'd have @ clients being used. i have upgraded several tortoisesvn-only work enviroments on past couple months , have had no problems. (of course, wise check in changes prior upgrading, in case.)

i went through many topics asking "why release build fail , not debug?", i'm across situation it's reverse. here release build works fine debug mode build breaks. possible reasons or situations can happen? reply appreciated. in advance. one of our friend gave direction towards memory freeing issue.. this same thing i'm facing... when build in release mode build successfully, when try build in debug mode fails/breaks @ point there statement freeing allocated memory.. code like: check if buffer null, , free if it's not null... if(buffer){ free(buffer) } when keep breakpoint on line (inside if loop) , check value in debug mode, appears "bad pointer".(0x000000) but question remains why went inside of if-loop though buffer has value 0x000000 ? i don't know details environment, debug environments take steps trigger bugs (e.g. filling free d memory invalid data), whereas release build not, giving more chances lucky. the prob

hibernate + hibernatetemplate + lazy loading + hql we using hibernatetemplate's find method passing hql query. how retrieve child elements have configured lazy loading? thanks. it depends. can elements of collection using join fetch in hql query, or can later call hibernate.initialize(entity.getsomelazycollection())

when adding array @ dynamodb put_item, there way tell preserve order of values of array? example: i'm adding array("2", "1", "4"), , it's added table 1, 2, 4. don't want dynamo mess array :) thanks in advance. no, arrays in dynamodb sets, don't preserve ordering. best alternative concatenate them string (using delimiter) , inserting string i.e. 2#1#4 , split them when read back.

i trying populate list of cities , mark them on maps, using ajax updating div element list of cities , each city element trying call addmarker() function supposed add marker on top of google maps. using firebug can see javascript tag function call, addmarker() not being executed what best approach forcibly call javascript function , update dom element ? here how addmarker() looks like: function addmarker(lat,lng,title_new) { new_marker = new google.maps.marker({ position: latlng_new, map: map, title:title }); } here how html.erb file looks <%= post.content %> <script type="javascript"> addmarker( <%= post.lat_long%>, <%= post.title%>); </script> </div> the dom element being updated after document has finished loading. i'm not clear doing, ajax , how addmarker work? sure document has been loaded before f

i want update row of table. to add used, session.add(unit) #here unit unit object of class unit session.commit() to update tried, session.merge(unit) session.commit() however, in database there other columns, e.g. create_by , created_on , updated_on , not set in unit object, these set null upon merge. you can modify properties of class use represent row , call session.commit() . example: # add new user user = user(name="john", age=20) session.add(user) session.commit() # modify user added user.age = 21 session.commit()

i know when using auto-properties, compiler creates own backing field behind screen. however, in many programs read learn from, see people explicitly write private int _backingfield; public int property { { return _backingfield; } } what difference between above, , below? public int property { get; private set; } i understand obvious use property when have side-effects in getter or setter, that's not case. also, understand have explicitly use backing field in case of structs, can't access members via properties. the difference have been able find way of calling value different inside class defined in. simple preference, or there more calling value through property or directly accessing field? simple conventions? there's not difference between 2 snippets - can't pass property reference, example, that's issue. however, if want field readonly, this: private readonly int _backingfield; public int property { { return _backingfield; } } the

i'm starting out celery in django project , couldn't wonder: elegant way start start celery's workers project? let me explain reasoning question. currently, recommended way start celery seems python manage.py celeryd in simpler setups , along lines of /etc/init.d/celeryd start in more complex ones. however, in first case, process feels fragile since process wouldn't start automatically, while second require quite bit of project-specific configuration ( virtualenv , settings etc.) latter demonstrates general feeling celery worker tied codebase it's part of , it's tied main project process, since celery worker without create tasks in practially useless (with 1 exception being celerybeat ). problem init.d scripts they'd need advanced logic handling several projects per server (with separate virtual environments, settings, paths etc.) so figured, might quite elegant configuration-wise start celeryd main process, e.g. spawn mod_wsgi withing apache

i have seen many articles using linq bind gridview , in using dataclasses . possible bind data grid view using linq out adding dataclasses .. can 1 give me sample code or working example on this i think may missing point, whatever source of data, long it's form of collection, can use linq objects query data. example: public partial class webusercontrol1 : system.web.ui.usercontrol { private readonly list<dataitem> _items; public webusercontrol1() { _items = new list<dataitem> { new dataitem {name = "fred"}, new dataitem {name = "dave"}, new dataitem {name = "john"}, }; } protected void page_load(object sender, eventargs e) { // data , use linq objects var filtereddata = getdata().where(i => i.name.startswith("f")).tolist(); // bind dat

i trying execute mysql database query on website depending on whether user has "liked" facebook page. have found few ways this, using php , js sdk's, namely using api /user_id/likes/page_id. when user has liked page, want add value data in database, thought of adding function called each time user visits site, , if it, add value database , have boolean value in there doesn't keep adding value. however, guessed waste of calls server if happened every time, not sure how go setting up, ideas? unless dealing huge volumes of users wouldn't worry because check on 1 row of indexed mysql table should quick (200 milliseconds or less entire request on normal internet connection.). , if data need stored on server, how possibly avoid trip server? unless store data in cookie.

ive been googling none of results worked me. here setup file setup( windows = [ { "script": "start.py", "icon_resources": [(1, "myicon.ico")] } ], ) the icon of actual .exe file should "myicon.ico". not happen , default icon. "myicon.ico" 32 x 32. i using windows 7. i've had problem before (though i'm using windows xp). recent snippet of code worked me: from distutils.core import setup setup( options = {'py2exe': {'bundle_files': 1}}, zipfile = none, windows = [{ "script":"myprogram.pyw", "icon_resources": [(1, "myicon.ico")], "dest_base":"myprogram" }], ) this creates 1 .exe file can use distribute (even includes windows libs -- use caution there) my .ico file 64 x 64 , used tool create jpg (something http://www.favicon.cc/ ) phot

i generating dynamic sql , ensure code safe sql injection . for sake of argument here minimal example of how generated: var sql = string.format("insert {0} ({1}) values (@value)", tablename, columnname); in above, tablename , columnname , , whatever bound @value come untrusted source. since placeholders being used @value safe sql injection attacks, , can ignored. (the command executed via sqlcommand.) however, tablename , columnname cannot bound placeholders , therefor vulnerable injection attacks. since "truly dynamic" scenario, there no whitelist of tablename or columnname available. the question thus: is there standard, built-in way check and/or sanitize tablename , columnname ? (sqlconnection, or helper class, etc.) if not, way perform task without using 3rd party library? notes: all sql identifiers, including schema, should accepted: e.g. [schema].[my table].column "safe" table1 . can either sanitize identifiers

i considering transitioning between menu screens in game using qstatemachine . however, i'm unsure how kick off code (e.g. show() qwidget ) upon transition between states occurring. can quite plain old signals (see commented out code), figure fancy animation upon switching screens using transitions. here's code: edit: updated per koying's suggestion. applicationwindow.h : #include <qtgui> #include <qstatemachine> #include "mainmenu.h" #include "loadgamemenu.h" class applicationwindow : public qmainwindow { q_object public: applicationwindow(); private slots: void mainmenubuttonclicked(); void loadgamemenubuttonclicked(); private: mainmenu* mainmenu; loadgamemenu* loadgamemenu; qstatemachine statemachine; qstackedwidget* stack; }; applicationwindow.cpp : applicationwindow::applicationwindow() { resize(800, 600); stack = new qstackedwidget(this); mainmenu = new mainmenu(); s
