i have worked on numerous projects have seen both setting of attributes new object in html form , when calling model.new(foo: 'bar') which correct way of doing in fashion of "best practices"? form: <%= form_for user.new, remote: true |f| %> <%= f.hidden_field :foo, value: "bar" %> <%= f.text_field :email %> <% end %> instance variable: #obviously set in controller @user = user.new(foo: "bar") <%= form_for @user, remote: true |f| %> <%= f.text_field :email %> <% end %> at first case, when validation of user not passed, empty form rendered, @ second case form filled fields rendered. it's because instance variable @user @ controller keep entered values. so recommend use second variant.

case: asp.net mvc, c# , extjs. user has got filter, can choose multiple values. there 13 such filters , user can add them or remove ui. problem: on server side i've got class getting filters values: public list<string> filter1 { get; set; } public list<string> filter2 { get; set; } ... public list<string> filter13 { get; set; } then select data database , convert ienumerable<dataclass> dataclass looks below: public string data1 { get; set; } public string data2 { get; set; } ... public string data13 { get; set; } then filter data this: if (filter.filter1 != null && filter.filter1.any()) { data = data.where(x => filter.filter1.contains(x.data1)); } ... if (filter.filter13 != null && filter.filter13.any()) { data = data.where(x => filter.filter13.contains(x.data13)); } so there 13 if , 13 same filter logic. , code looks horrible. there way make more beautiful filter? added: filter1 can applied data1 ,

i made tweak aspx.vb file on test server, small change custom error message being written in code, making copy of file, changing text , replacing file on server. however, change not reflect when go page browser. i thinking had file not being compiled. however, seems if aspx.vb file should compiled dynamically. there setting ensures happens? copy of web.config file: <?xml version="1.0" encoding="utf-8"?> <configuration> <system.web> <compilation debug="true" strict="true" explicit="true" /> <authentication mode="windows" /> <identity impersonate="true" /> <customerrors mode="on" /> </system.web> <system.webserver> <validation validateintegratedmodeconfiguration="false" /> <modules runallmanagedmodulesforallrequests="true" /> <defaultdocument> <files>

i have winforms application has perform action every time when returning external application (i.e. focus has been lost application, alt-tabbing program , back). is there application event handler this? i have looked activate , deactive handlers of form, these handlers fired when form receives focus (when closing messagebox or closing subform). windows sends wm_activateapp message window when being activated, , when being deactivated. want handle, when wparam true (indicating activation). winforms not wrap event (at least not i'm aware of), you'll need add code form's window procedure manually: public class myform : form { // other code protected override void wndproc(ref message m) { const int wm_activateapp = 0x001c; switch (m.msg) { case wm_activateapp: { if (m.wparam.toint32() != 0) { // application's window being activated,

i new ajax/jquery. developing application takes loan number input. when ever textbox field loose focus should display information particular loan getting information database. i developing in mvc. view consists loannumber = textboxfield. contact name = textboxfield phone = textboxfield. below sample code tells whether loan number exists or not. $("#loannumber").blur(function () { var num = $("#loannumber").val(); var status = $("#divstatus"); $.post("/fnmaimport/checkloannumber", { loannumber: num }, function (data) { if (data == true) { status.html("<font color=green>'<b> loan number " + num + "</b>' available!</font>"); } else { status.html("<font color=red>'<b> loan number " + num + &q

i'm creating open-source .net web development framework called "expressforms". uploaded project github: https://github.com/daniellangdon/expressforms . i used nuget set code run latest versions of asp.net mvc , entity framework; these saved in "packages" directory below solution. can see default, git ignores directory when uploading project github. when download project github directory, directory missing , solution won't build. what need make developer can download code github , build right away without fuss? i still new git, it's i'm missing basic. sounds need enable nuget package restore in newly downloaded solution . when using nuget github, github ignores files under packages directory because it's not idea commit binary files (like dll libraries) git, because causes git repos become bloated in size on time because have keep each version of binary in repo history forever (unless go , erase them git filter-branch ).

i have 2 vectors, lets v1 = (a,b,c,d,e) , v2 = (e,h,t,b,w) , want third vector containing common elements of v1 , v2 , in case v3 = (e,b) i've seen asked in c++, cant see lua. i assume when saying vectors, mean v1 , v2 both array-like tables, this: local v1 = {1,2,4,8,16} local v2 = {2,3,4,5} then can this: local v3 = {} k1,v1 in pairs(v1) k2,v2 in pairs(v2) if v1 == v2 v3[#v3 + 1] = v1 end end end

we plan use federated azure sql database in our next project, because need database solution can handle large amount of concurrent requests - inserts, selects, updates, etc. however, there hard limit of 180 concurrent requests on database instance. the problem if use federations, every connection must connect federation root first (just regular sql server database). server redirect our client federation member contains required data: -- statement redirect federation root db federation member db use federation myfederation (uid = 0xff) reset, filtering = on; does mean, there no (easy) way scale beyond 180 concurrent requests on federation root server? you should @ sql database premium reservations, eliminate connection limit. http://msdn.microsoft.com/en-us/library/windowsazure/dn369873.aspx it in preview currently, doesn't mean can't start developing on it. don't sla in preview, retry block , using multiple instances mitigated.

for augmented reality web app smartphones i'm trying calculate compass heading when user holding device in hand, screen in vertical plane , top of screen pointing upwards. i have taken suggested formula http://dev.w3.org/geo/api/spec-source-orientation (see worked example) , implemented following function: function compassheading(alpha, beta, gamma) { var a1, a2, b1, b2; if ( beta !== 0 || gamma !== 0 ) { a1 = -math.cos(alpha) * math.sin(gamma); a2 = math.sin(alpha) * math.sin(beta) * math.cos(gamma); b1 = -math.sin(alpha) * math.sin(gamma); b2 = math.cos(alpha) * math.sin(beta) * math.cos(gamma); return math.atan((a1 - a2) / (b1 + b2)).todeg(); } else { return 0; } } while .todeg() number object extension courtesy http://www.movable-type.co.uk/scripts/latlong.html /** converts radians numeric (signed) degrees */ if (typeof number.prototype.todeg == 'undefined') { number.prototype.todeg = f

currently returning list of items have date range. of appointments have expired , others have not happened yet. displaying appointments have not expired yet. want check if appoinments have expired show first item. var curapt = myappts.where(d => d.appt.endtime > datetime.utcnow).first(); if myappts.where(d => d.appt.endtime > datetime.utcnow) == null var curapt = myappts.first(); how can structure consider both cases? firstordefault , null coalescing operator ( ?? ) : var curapt = myappts.firstordefault(d => d.appt.endtime > datetime.utcnow) ?? myappts.first(); however, make less exception prone if have default value show if there no appointments @ all, chain null coalescing operator that: var curapt = myappts.firstordefault(d => d.appt.endtime > datetime.utcnow) ?? myappts.firstordefault() ?? yourdefault;

i'm trying qt5 working on ubuntu 12.04. downloaded 32-bit installer http://qt-project.org/downloads , let install in home folder. i had add ~/qt/5.1.0/gcc/bin path qmake work, when try make hello qt example (using qt4 book), when running make, cannot find qapplication or qlabel header. when replace them qtwidgets/qapplication , finds header, undefined references when linking. this command make executes: g++ -c -pipe -o2 -wall -w -d_reentrant -fpie -dqt_no_debug -dqt_gui_lib -dqt_core_lib -i../../../../qt/5.1.0/gcc/mkspecs/linux-g++ -i. -i. -i../../../../qt/5.1.0/gcc/include -i../../../../qt/5.1.0/gcc/include/qtgui -i../../../../qt/5.1.0/gcc/include/qtcore -i. -o hello.o hello.c i managed figure out it's qmake -project doing wrong. when make app in qt creator (which works), .pro file has lines qt += widgets , not there when run on command line. i found answer using qmake --help . says: note: created .pro file need edited. example

i implementing ierrorhandler in order centralize of error handling wcf service in 1 place. works well: public class serviceerrorhandler : ierrorhandler { public bool handleerror(exception error) { // ..log.. } public void providefault(exception error, messageversion version, ref message fault) { // ..provide fault.. } } now, we're using ninject inject dependencies in rest of service, , i'd same here. since wcf constructing objects based on configuration, , don't think have hooks process, need use property injection: [inject] public iloggingservice logger { get; set; } however, never seems injected. tried using ninject's mvc extensions set serviceerrorhandler allow injection filter, didn't seem trick. there way make happen? late answer, can inject dependencies ierrorhandler creating custom servicehost , let's testservicehost . in testservicehost need do: implement constructor ier

i have i/o intensive task (it crawls webpages). want make task available via web api , built javascript+html interface on top of it. , want in python, since have set of python scripts implementing task. now i'm looking python web framework this. what web framework can recommend i/o intensive web page? some more details: i worked flask , liked it i don't need user management, need sessions i want build actual ui angular/ember since it's web crawling, i'd go scrapy crawling tool , twisted event-driven networking engine/web-framework. scrapy built on top of twisted, set might choice you. also, take @ tornado web framework using non-blocking i/o. hope helps.

i have kendo grid using asp.net mvc wrappers , has multiple columns (say col 1 , 2). grid set incell editing mode. columns 1, 2 need able edited (or preventing editing) based off values of each other specific row. for instance, if column 1 value true column 2 allowed edited. if column 2 value false, column 2 not allowed edited. any ideas? i found similar example using client side extensions. when editing grid, how disable specific fields row? is there similar way using asp.net mvc wrappers? we ran across similar issue , found following solution. might not right way it, seems work disabling field when row existing , enabling when new. logic should able swapped logic need. in kendo mvc bindings. "disableonedit" name of javascript function call when cell goes edit mode. @(html.kendo().grid<yourmodel>() .name("grid") ... .events(events => events.edit("disableonedit")) ... in javascript: function disableonedit(e) {
