i have parent-child relationship between 2 objects. parent :has_many :children child :belongs_to :parent when creating new parent, in same controller, i'm creating child. @mom = parent.new @child = child.new @mom.children << @child that seems go okay, parent has 1 more attribute - parent has favorite child @mom.favorite_child = @child seems should work, except let's 61st child in database, gets id of 61 (and know happening, because when check database, child record has id of 61). reason, when assign @child parent's "favorite_child" attribute, "favorite_child" gets set "1" - when need set "61". clues? seems parent needs like class parent has_many :children has_one :favorite_child, :foreign_key=>'favorite_child_id', :class_name => 'child' otherwise, doesn't know it's foreign key relationship, , you're trying assign object integer.

i can't make system.linq (aka linq objects) work. running monodevelop 2.2.1 in ubuntu 10 lucid lynx mono 2.4.4. they advertise in site implemented linq, can't find enumerable.range or toarray() . what's wrong? i guess need is: in project options set "runtime version" "mono/.net 3.5" add reference system.core package (right click references in solution explorer) add "using system.linq" module after code should compile , execute hope helps, regards

we need save selected new page size session. we have tried pagesizechanged event newpagesize returns 0. is there way new page size value? how? thanks. i able need protected void page_load(object sender, eventargs e) { int newpagesize = ((raddatapager)radlistview1.findcontrol("raddatapager1")).pagesize; if ((int)session["imagesperpage"] != newpagesize) { session["imagesperpage"] = newpagesize; } radlistview1.pagesize = (int)session["imagesperpage"]; } this seems kind of hack. other more elegant ways this?

i need set timeout on python's socket recv method. how it? the typical approach use select() wait until data available or until timeout occurs. call recv() when data available. safe, set socket non-blocking mode guarantee recv() never block indefinitely. select() can used wait on more 1 socket @ time. import select mysocket.setblocking(0) ready = select.select([mysocket], [], [], timeout_in_seconds) if ready[0]: data = mysocket.recv(4096) if have lot of open file descriptors, poll() more efficient alternative select() . another option set timeout operations on socket using socket.settimeout() , see you've explicitly rejected solution in answer.

this might silly question, but... i've been writing number of classes utilize non-copyable members. these classes never initialized via copy constructor in source. when try compile without supplying own copy-constructor, g++ throws out many errors how can't build default copy constructor, due non-copyable member objects. is there way tell compiler not give me copy constructor? edit: yeah... feels silly ... had case invoking copy-constructor accident in boost::bind call. lesson learned. if don't cause copy-constructor called not error if compiler unable generate one. sounds (possibly indirectly) causing copy-constructor used. you can suppress compiler generated 1 declaring own copy-constructor (you don't need define if you're not using it). can place in private section of class. if changes error copy-constructor inaccessible or link errors causing copy-construtor used , need analyze why is.

(title updated) following on this question, have clearer picture what's going on... i have mfc application no main window, exposes api create dialogs. when call of these methods repeatedly, dialogs created parented each other instead of being parented desktop... have no idea why. but anyway after creation, unable change parent null or cwnd::getdesktopwindow()... if call setparent followed getparent, nothing has changed. so apart weird question of why windows magically parenting each dialog last 1 created, there i'm missing able set these windows children of desktop? updated : have found reason this, not solution. dialog constructor, end in: bool cdialog::createindirect(lpcdlgtemplate lpdialogtemplate, cwnd* pparentwnd, void* lpdialoginit, hinstance hinst) { assert(lpdialogtemplate != null); if (pparentwnd == null) pparentwnd = afxgetmainwnd(); m_lpdialoginit = lpdialoginit; return createdlgindirect(lpdialogtemplate, pparentwnd, hi...

i have rails model adding validations , seem have run bit of weirdness 1 of validators. so here table working (from schema.rb): create_table "clients", :force => true |t| t.string "name" t.string "last_contact" t.integer "contacting_agent" t.date "last_payment_date" t.float "last_payment_amt" t.datetime "created_at" t.datetime "updated_at" t.string "office" t.integer "client_id" end i have normal view, with: <%= error_messages_for 'client' %> <h1>new client</h1> <% form_for @client |new| %> <table id='newform'> <tr> <th>field</th> <th>value</th> </tr> <tr> <td> id </td> <td> <%= new.text_field :client_id %> </td> </tr> <tr> <td> name </td> <td...

what simplest way of getting meta description / keywords onto _layout page? similar how page title nice. such as <title>@viewbag.title</title> <meta name="keywords" content='@viewbag.keywords'/> <meta name="description" content='@viewbag.description'/> my view like: @{ viewbag.title = "contact me"; viewbag.keywords = "my, keyword, list, etc"; } your view should not responsible of (do not add logic views). instead, it's action method should specify meta information. check answer here: asp.net mvc - strategy including seo information such meta keywords , descriptions the answer still apply, although should use viewbag instead of viewdata .

somewhat straightforward: asp:validators still perform validation when they're in invisible containers? how if controltovalidate target invisible? for example: <asp:panel id="mypanel" runat="server" visible="false"> <asp:textbox id="mytextbox" runat="server" /> <asp:requiredfieldvalidator id="myrfv" runat="server" controltovalidate="mytextbox" /> </asp:panel> above validator in invisible panel. myrfv still perform validation? how if mytextbox invisible instead? i'm asking because have specialized validators in aspx, wherein have panels hidden/shown dynamically. while i'm disabling validators themselves, i'm curious whether they'll automatically disable anyway. thanks guys! :d if panel invisible nothing rendered, there no validator. in other case control validate invisible try validate textbox , return false(not valid) defa...

i have isapi filer , want add logic based on incoming domain ( server farm hosts many domains). there domain list dynamic , can export these domain list text file , read isapi , there way keep file in memory (is array or linked list) save io call. similar global application state . how worker processes distributed across servers? have 1 server 1 worker process, or multiple servers? if have 1 server 1 worker process, can read file static array or string manage (just make sure account concurrent threads reading/modifying simultaneously) if have multiple worker processes on 1 server, can use named shared memory. i've used before in isapi filters share information, , works pretty well. should take care of concurrency you. can read more here: http://msdn.microsoft.com/en-us/library/aa366551%28v=vs.85%29.aspx if you're spread across multiple servers, use distributed cache memcached. more complex set up, it'll give performance. there's thread on setti...

in legacy codebase have large class far many fields/responsibilities. imagine pizza object. it has highly granular fields like: haspepperoni hassausage hasbellpeppers i know when these 3 fields true, have supreme pizza. however, class not open extension or change, can't add pizzatype, or issupreme(), etc. folks throughout codebase duplicate same if(a && b && c) issupreme) logic on place. issue comes quite few concepts, i'm looking way deconstruct object many subobjects, e.g. pseudo-backwards builder pattern. pizzatype pizzatype = pizzaunbuilder.buildpizzatype(pizza); //pizzatype.supreme dough dough = pizzaunbuilder.builddough(pizza); is right approach? pattern exist already? how adapter pattern? basically wrapper class has functionality want can go , forth pizza class. menupizza mypizza = new menupizza(pizza); pizzatype pizzatype = mypizza.getpizzatype(); doughtype doughtype = mypizza.getdoughtype(); and provide reverse functio...

i have 2 columns company , product. i use following query products matching particular string... select id,(select name company product.cid=company.id) company,name,selling_price,mrp product name '$qry_string%' but when need list products of specific company how can do? i tried following in vein select id,(select name company product.cid=company.id) company,name,selling_price,mrp product company '$qry_string%' help me what trying not require subquery, simple join enough. try this: select c.name, p.id, p.name, p.selling_price, p.mrp company c inner join product p on c.id = p.cid c.name '$qry_string%' i think problem query tried cannot use fields result of subquery (in case, "company") in where clause. might try having instead.

i'm building network application uses bouncycastle cryptography provider. let's have generate keypair: ecparameterspec ecspec = ecnamedcurvetable.getparameterspec("prime192v1"); keypairgenerator g = keypairgenerator.getinstance("ecdsa", "bc"); g.initialize(ecspec, new securerandom()); keypair pair = g.generatekeypair(); i'm confused why you're getting instance of ecdsa keypairgenerator. why doesn't ec ? know there's ecdh key type shipped bouncycastle, thought 2 represented same stuff points on curve -- or wrong theory behind it? the reason ask right application uses ecdh fine establish aes secret key, want use same ec key sign each message using ecdsa. ecdsa , ecdh distinct standards (ansi x9.62 , x9.63, respectively), , used in distinct contexts. x9.63 explicitly reuses elements x9.62, including standard representation of public keys (e.g. in x.509 certificates). hence, ecdsa , ecdh key pairs largely interch...
