my goal use greasemonkey-style user script in google chrome enable remembering of passwords on specific form has autocomplete="off" attribute set. chrome's developer tools indicate autocomplete="on" being set script, not have expected effect of allowing storage of passwords on form. why doesn't work? example chrome offers remember passwords entered on test page (expected): <html><body><form action=""> <input type="text" name="username" /> <input type="password" name="password" /> <input type="submit" name="submit" value="log in" /> </form></body></html> chrome not offer remember passwords entered on test page (expected): <html><body><form action=""> <input type="text" name="username" /> <input type="password" name=&quo

css - Possibly transparent WebKit-Overlay in Gtk/Cairo? -

-
i'm building application, cross-platform (linux, win, os x), , graphics stuff via cairo(mm), supported little bit of gtk+ scaffolding (i.e. drawingarea ). need ui elements, require custom look. ideally should displayed transparent overlay (i.e. different opacities different parts of ui). as gtk+ hard customize (e.g. want edit-field suggestion-list above it), , me knowing how i'd achieve html/css, question popped up: why not let libwebkit handle ui stuff? i don't have experience webkit, need know is: does above reasoning make sense else? css has opacity , can interface webkit in such way renders onto rgba-offscreen surface, alpha-values inherited layout-processing of css styles? even if 2. not work, has used libwebkit on offscreen surface, afaik requires redirection of keyboard , mouse interactions, via gtk+s provisions? is possible render web content on clear background using webkit? gets.

possible duplicate: synchronized jlist , jcombobox? hello, in java swing, what's best way jlist , jcombobox synchronized in terms of data, i.e., have same list of items @ given point of time? basically, if add items (or remove items from) one, other should reflect change automatically. i've tried doing following, doesn't seem work: jlist list = new jlist(); jcombobox combobox = new jcombobox(); defaultlistmodel listmodel = new defaultlistmodel(); // add items listmodel... list.setmodel(listmodel); combobox.setmodel(new defaultcomboboxmodel(listmodel.toarray())); you're creating 2 models in code. when construct new defaultcomboboxmodel passing in listmodel contents constructing second model starts same contents first. won't update same. want 2 components share model. in other words... jlist list = new jlist(); jcombobox combobox = new jcombobox(); defaultcomboboxmodel listmodel = new defaultcomboboxmodel(); // add items listmodel..

c# - Is there a queriable distributed cache with high availability option for Windows? -

-
we trying integrate sort of distributed cache our system. have 2 major requirements: high availability, i.e. automatic data replication mirroring machines if 1 goes down, data around. searchabilty/quaribility of cache data, i.e. there need ranged searches. optional: returning complete snapshot of data stored. optional: ability persist cached data on periodic basis. so far have sharedcache candidate because allows @ least searching using regex. that's inherently slow though. sharedcache doesn't support high availability. windows app fabric offers no search far understand (if wrong can awesome). what options? ask? should give , think sort of custom solution? definitely include membase memcached list of considerations. solid , stable. can use "memcached" part if want there nosql document database available (which of course can used "cache persistence" too).

i haven't seen radio buttons long time. used anymore, , if used , used them? what best alternatives radio button? can use instead of radio buttons? i had far "settings" page on gmail account before found radio button on web. the other widget provides simple "pick 1 choice many" option in html document <select> element. you can use multiple submit buttons same effect — submit form @ same time, isn't appropriate (although "preview" or "save" decisions).

asp.net mvc 3 - Enable Yellow Screen of Death on MVC 3 -

-
i had take on mvc 3 project developer. 1 of first things did stop yellow screen of death exceptions logged file. generic message saying error has occurred. i switch on (since gets annoying having check through logfiles whole time) - how do this. i checked through web.config can't see happens. i did try doing customerrors=off, didn't anything. removed global error handling attribute, didn't anything. on further clarification, seems if exception occurs in controller yellow screen of death, if occurs in (razor) view standard generic error. you can see web.config here can see global.asax here in global.asax can remove filters.add(new handleerrorattribute()); public static void registerglobalfilters(globalfiltercollection filters) . as pointed out in comments - problem custom base controller overriding onexception method.

we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing.

c++ cli - Wrapper to unmanaged code -

-
how build wrapper unmanaged code in order use in managed code, , when have that? you don't need wrapper, many dlls straight-forward exported c functions can pinvoked [dllimport] attribute. exception c exports poorly designed dll requires client code release memory, can't done managed code since doesn't have access allocator. the case have have wrapper native c++ class. managed code cannot pinvoke directly since doesn't know how create instance of class (which requires knowing size of object , calling constructor) nor how destroy (which requires calling destructor). pretty easy in c++/cli. mechanical, swig project can automatically. learning tool more of investment learning how write wrapper.

c# - Enum.IsDefined with flagged enums -

-
i'm reading book c# 4.0 in nutshell , way think excellent book, advanced programmers use reference. i looking on chapters basics, , came across trick tell if value defined in enum when using flagged enums. book states using enum.isdefined doesn't work on flagged enums, , suggests work-around : static bool isflagdefined(enum e) { decimal d; return (!decimal.tryparse(e.tostring(), out d); } this should return true if value defined in enum flagged. can please explain me why works ? thanks in advance :) basically, calling tostring on enum value of type declared [flags] attribute return defined value: somevalue, someothervalue on other hand, if value not defined within enum type, tostring produce string representation of value's integer value, e.g.: 5 so means if can parse output of tostring number (not sure why author chose decimal ), isn't defined within type. here's illustration: [flags] enum someenum { somevalu

asp.net - Accessing code behind functions from WebMethod -

-
i have code behind page has several method; 1 of them page method. [webmethod] public static void resetdate(datetime thenewdate) { loadcallhistory(thenewdate.date); } protected void loadcallhistory(datetime thedate) { bunch of stuff } the method loadcallhistory works fine when page loads , can call other methods inside page. however, in web method part, gets underlined in red error "an object reference required non-static field". how access functions page method part of code? thanks. you cannot call non-static method static context without having instance of class. either remove static resetdate or make loadcallhistory static. however, if remove static resetdate must have instance of use method. approach create instance of class inside resetdate , use instance call loadcallhistory , this: [webmethod] public static void resetdate(datetime thenewdate) { var callhistoryhandler = new pages_callhistory(); callhistoryhandler.loadcallhisto

vb.net 2010, .net 4 hello, i (something like) following: \#const t = "byte()" public class myclass inherits somegenericclass(of t) .. other code .. end class and have act same if i'd typed public class myclass inherits somegenericclass(of byte()) .. other code .. end class it's not have way, i'm curious if such thing possible. thanks in advance! brian no, not possible. visual basic , c# designers decided not allow c-like preprocessor, because felt led lot of errors , confusion. easy write c macros behave in unintended ways, , vb , c# designers felt safety broad range of developers took priority. therefore defines in vb , c# 'defined' or 'undefined' rather having values. eric gunnerson discusses c# perspective here , , think design reasoning vb.net same.
