i want capture users screens connected machine. how can that? i want create windows service capture users screen. thanks laxmilal you can using windows terminal service (wts) api. need do: 1. use local system system service account. other accounts not work. 2. call wtsopenserver, using wtsenumeratesessions retrieve list of sessions 3. list of wts_session_info structures. each item there represents sessions. interested in sessions state wtsactive. 4. in loop call createprocessasuser each session identified in previous step. specify sessionid wts_session_info structure have session. name of process run favorite screen capture utility. did not use of those, quick search on internet turns few options.

if return object session (httpcontext.current.session) private member of objects type , modify it, e.g. rename attribute or add objects internal list member. changes persisted if on page request same object session...will updated values updated on previous page. in other words object persisted, or have re-save object session once change on every page. appreciated. thanks if actual object yes, modifying version maintained session , it's values saved. if not reference type, string, have reference actual session value modify (ie: session["key"] = value). however, caution against storing real objects in session. session works serializing , deserializing values on every single page load. more put session more work framework has perform before beginning execute page. because of how works should put values in session need across entire site. before considering putting in session ask myself following: is needed entire site or close it? is time load i

i read via system.setproperty("apple.awt.filedialogfordirectories", "true"); users can select directories via filedialog , filedialog evoces native file chooser, want in line above reads: apple.awt... , mean option work on mac osx? if(no) { great } else { can implement on other operating systems than? } thanks help! ps: know lot of people suggest use of jfilechooser, in case i'd prefer filedialog, except if that's impossible it feared. awt used native libs underneath. osx has feature directories only, windows not. youre change use dialog not based on awt, i.e. swing or swt. you can define interface platform specifc implementations. gives looking dialog on osx , works on other platforms. that's do.

i'm using default entitylisteners (preupdate , prepersist) write create , update timestamps entities. when new child added collection (onetomany) , persist called parent record send entitylistener , timestamps updated. problem don't want update parent if new child record added collection. there way check if entity modified (inside entitylisterner)? andreas this might (not tested, think work). event descriptorevent got, object entity want check changes. unitofworkimpl uow = (unitofworkimpl) event.getsession(); classdescriptor descriptor = uow.getdescriptor(object); boolean isnew = uow.isobjectnew(object); if (isnew || descriptor.getobjectchangepolicy().shouldcompareexistingobjectforchange(object, uow, descriptor)) { objectchangeset changes = null; if (isnew) { changes = descriptor.getobjectchangepolicy().calculatechangesfornewobject(object, changeset, uow, descriptor, true); } else {

using curl_multi, have loaded 3 url's , printed array. 1) how can set timestamp on output let me know when each url run? 2) how can explode array display data , timestamp, excluding text "array ( [0] =>", "[1] =>", "[2] =>" , " )"? code <?php function multirequest($data, $options = array()) { // array of curl handles $curly = array(); // data returned $result = array(); // multi handle $mh = curl_multi_init(); // loop through $data , create curl handles // add them multi-handle foreach ($data $id => $d) { $curly[$id] = curl_init(); $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d; curl_setopt($curly[$id], curlopt_url, $url); curl_setopt($curly[$id], curlopt_header, 0); curl_setopt($curly[$id], curlopt_returntransfer, 1); // post? if (is_array($d)) { if (!empty($d['post'])) { curl_setopt($c

gcc 4.4.1 c89 i using api our previous programmer has produced. however, bit confused why masking in why. what reason or hex mask. , reason have ipev_error_mask or'ed ipev_start. why not have hex values? #define ipev_mask 0x9000 #define ipev_error_mask (ipev_mask | 0x0800) #define ipev_open (ipev_mask | 0x01) #define ipev_start (ipev_mask | 0x02) #define ipev_media_fail (ipev_error_mask | ipev_start) many suggestions, not sure part unclear you, i'll explain everything. first of all, they're bit flags. bit flags way of storing lot of boolean values inside single number. instance, typical 32-bit integer can store 32 boolean values. has dual advantages of being compact in memory, , being able pass around several values @ once. drawback is, of course, access single value have mess around bitwise operators. approach typically not used when dealing boolean values in code, used when storing values or passing

i've noticed whenever add tables / stored procs / functions / whatever sql server database, takes while code completion pick part of database. this annoying since code completion , syntax highlighting become totally broken in workflow scenario create table , start writing queries or whatever deal new object. does know how code completion / syntax highlighting engine update it's view of in database rid of these spurious invalid object name errors? i understand it's late answer question maybe someone. you can refresh intellisense cache ctrl+shift+r , , wait 5-10 seconds.

recently asked question on regarding changing row background color on click , hover using jquery. below link it, , implemented solution marked answer. problem when having lot of rows, hover click takes lot of time. using ie8 latest version of jquery. below link question jquery row hover , click events here code implemented: http://jsfiddle.net/epurh/ if hover , click, working , fast less rows, if there lot of rows/columns, gets slow , throws error if want stop script. when compare same in firefox, fast. have problem in ie8. can 1 suggest workaround this? in click handler, add class <tr> clicked when comes time remove class on .children() , can target specific row. $(".simplehighlight").click(function() { $(this).addclass('wasclicked').children().addclass('clicked'); // sibling <tr> class "wasclicked" // , remove class, , "clicked" class children $(this).siblin

i understand 1 of main benefits using object is, real objects instead of system wide functionality. objects system wide accessible. beside of being more "pure" additional benefit scala "objects" offer. i bet there number can't figure out which. objects independent entities, e.g. can used method arguments, target implicit conversions, , case objects in pattern matching... objects can inherit classes or traits an object has own type objects can restrict access of members, companion class: . object x { private[this] val z=1 } class x { import x._ //won't compile println(z) }

this far have got. thinking stuff string array, format , recast string. //input search term console.writeline("what search query?:"); string searchterm = console.readline(); //stuff search term array split out string separator = " "; //assumes search terms separated spaces string[] searchtermarray = searchterm.split(separator.tochararray()); //construct search term string searchtermformat = ""; (int = 0; < searchtermarray.length; i++) { searchtermformat += searchtermarray[i] + "+"; //console.writeline(searchtermformat); } desired output word1+word2+word3 where number of words not fixed. you're looking string.join("+", searchtermarray) you're trying write searchterm.replace(' ', '+') you should writing uri.escapedatastring(searchterm)

i have multiple calls membership.getuser() , can't seem find built in cope (without hitting database multiple times). i first looked static variables before realising not suitable. know can use sessions need hash/encrypt userid make safe, fine didn't want without checking if there built in way within .net membership provider is there built in way of remembering value userid , safely storing current user? membership.getuser() indirect call class membershipprovider's method: public abstract membershipuser getuser(string username, bool userisonline); so, can write class derives membershipprovider you're using (for example sqlmembershipprovider or activedirectorymembershipprovider, or custom one) , override method using clever cache mechanism. then need change web.config declare new membershipprovider class: <membership defaultprovider="myprovider"> <providers> <clear/> <add name="myprovider&qu

following scenario. i have called domain can have multiple states (statekey-statevalue pair) in it. the same statekey can present in multiple domains different statevalue. e.g. statekey named 'economiccapital' may present in domains 'england', 'america' values 'london', 'washington' respectively. classes corresponding these in common library can consumed @ client or service side required. i have winform application in can select specific domain. in string, wherever encounter statekey, want replace statevalue selected domain. i can think of following designs: establish composition relationship. domain can composed of states. when want statevalue of statekey, can object of required domain , can extract statekey states collection composed in it. but there can large number of instances statekey used, not think approach quite snce requires finding domain object collection of domains , iterating through state collection find parti

i'm in need implement openid authentication in kohana 3 application. searching , found http://code.google.com/p/kohanamodules/wiki/openid#whb 2.x versions of kohana , can't used in 3.x. there implementations? read article ( demo app ). , here controller source.

i have implemented controller create new users. when creates user redirects index() . what want get redirected when ok, stay in current page , see error when failed. i'm using jquery ajax mvc . my controller looks this: [authorize] public actionresult createuser(string username) { try { //here logic create user } catch (exception ex) { string error = string.format("error creating user: {0}", ex.message); response.statuscode = 500; response.write(error); } return redirecttoaction("index"); } the form submit intercepted jquery, , call made ajax: $("#new-user-form").submit(function() { var form = $(this); $.ajax({ type: "get", url: form.attr('action'), data: form.serialize(), success: function(data, textstatus, xhr) { //at point redirect }, error: function(xhr, textstatus, errorthrown) {

i have application uses uitabbarcontroller, , inside each tab have navigation controllers. make 1 of views reload after action happens in view, when user goes view - it's updated. possible? thanks bunch! the simplest way accomplish put loading code viewwillappear: instead of viewdidload . while viewdidload may called once, when view initialized, viewwillappear: called time view controller presented, whether in tab bar, in navigation controller, etc., gives nice hook implement loading , layout functionality.

each source file has function: unsigned char test(){ //return true if tests succceed false otherwise } everytime sourcefile gets recompiled want test function of file run on execution of executable , if tests return false halt. however, want code test code hasnt been run since build. i thinking use makefile system problem since makefiles recompile changed code want. therefore, thinking of adding command line arguments. saw example in used echo , date add time last modified. code write time last modified save file on successful execution of test code compare next time. is there better way? 1 doesnt rely on make? @ least there way without relying on spefic unix commands? lastly, if isnt possible, command line addition file like. yes, make file.t target dependant on file.c. file.t generated based on successful completion of test. it'll easier if call test function "main" , wrap in #ifdef's this: #ifdef test int main() { if (test_someth

i have listbox in wp7 application , retrieve list of visible items in listbox. actually, trying retrieve object visible when application tombstoned, can resume , write listbox.scrollintoview(lastvisibleitem); if matters, listbox bound collection of custom objects datatemplate customizing way looks. thanks in advance. it's possible work out how far list has been scrolled using technique detailed in this answer . you calculate item(s) displayed based on size of list , height of items displayed. if different items can diffferent sizes becomes more difficult need consider height of each individual item. you need remember part of item may displayed.

some background information. distributed application multiples nodes. 'communication' thread sends , receives messages sent between these nodes. cannot changed. a 'dostuff' thread asks 'communication' thread send message node. needs wait response other node. 'communication' thread receive response message. needs deliver message correct 'dostuff' thread. i unsure sort of information needs stored @ node or within message ensure correct thread receives response message. looking advice upon how achieve this. reading :) you want attach sort of message id outgoing message included in response. sequential number or uuid job. communicator thread can keep track (a map?) of "dostuff" thread waiting given response , pass back. you keep track of when request sent if response isn't received communicator thread can notify dostuff thread response wasn't received.

i have piece of code i've written , read in order work correctly must use parameters did , works perfectly, cant figure out life of me parameters , how work. read through ton of articles on web couldn't figure out how parameters work. how 1 parameter know grab instructions another. whole idea frustrating. kind of side question. can getelementby class instead of id or there similar getelementbyid() classes? in advance. below code in script.js file: function setvalue(field) { if(''!=field.defaultvalue) { if(field.value==field.defaultvalue) { field.value=''; } else if(''==field.value) { field.value=field.defaultvalue; } } } and called script run code below: <textarea id="info" class="textarea" name="comment" cols="40" rows="10" onfocus="setvalue(this)"

how can group several mfc radio boxes single group? is possible bind variable (preferably integer indicating checked radio or boolean array) such group. binding mean using ddx_* . the radio buttons must adjacent in tab order. tab order editable visual studio's dialog editor (find 'tab order' menu item, ctrl-d shortcut in vs 2005). have arrange radio buttons clicking them in order. first radio button in tab group have set group property true. should select control follows group of radio buttons , set group property true too. way radio buttons form group , behave expected (check see how keyboard arrows work when of radio buttons has focus). you can bind set of radio buttons after configuring them above via ddx_radio macro. see: http://msdn.microsoft.com/en-us/library/fchz3yh5(v=vs.80).aspx

with jquery, there way make val() return empty string instead of 'undefined' when called against empty list of elements? e.g., have code: var x = $('#my-textbox-id').not('.watermark').val(); the idea want value of textbox, want empty string if showing watermark (i don't want watermark value!). the selector works, don't want 'undefined' - want empty string ''. you can write (...).val() || "" . only use text fields; replace false or number 0 "" .

when httpget handling create action method returns view() , causes form fields uninitialized. why javascript validation not triggered when users views blank form? i don't know inner workings, i'll give guess ;-) first of all, has nothing whether or not [httpget] or [httppost] -- that's way works. your average [httpget] methods this: [httpget] public actionresult index() { // data database return view(data); } there aren't parameters in method, because want user hit controller when type in url (i.e. home/index ). your usual [httppost] method might this: [httppost] public actionresult create(mymodel mymodel) { if (modelstate.isvalid) { // stuff } else { return view(mymodel); } } i believe validation attributes aren't triggered until bind form values model , hit create(...) controller. if [httpget] happened take in model parameter, validation triggered @ point well. when return view

suppose have repository returns list of post s. repository interface has getall() method suggests. now in keeping theory shouldn't putting domain logic in repository, want intercept calls concrete getall() method such can add following logic getall() result: return getall().orderbydescending(p => p.posted).tolist(); the reason want intercept because (1) don't want have client remember call extension method ( orderbydescending or useless wrapper of that), want called every time , (2) don't want have concrete implementations have remember order getall() result - want logic in single place external repository. what's easiest way this? i'm using structuremap if can intercept might low cost option. don't think sm intercepts method calls, creation of object instance? do need go proxy or mixin pattern? need go all-in castle dynamic proxy ? or there another method should consider or perhaps combination? i'm interested in concrete suggest

i looking ios nsscroller - track appear when scrolling - inertia support - same , feel. do know if exists? thanks , regards, not i'm aware of. have subclass nsscrollview in addition nsscroller. subclassing nsscroller allow produce , feel of scrollbar visible during scrolling. the inertial scrolling have built nsscrollview itself, although know mac's using trackpad , have option turn on inertial scrolling in system preferences.

i'm trying select each first word, wrap in specific span. lorem ipsum dolor sit amet, consectetur adipiscing elit. cras sagittis nunc non nisi venenatis auctor. aliquam consectetur pretium sapien, eget congue purus egestas nec. maecenas sed purus ut turpis varius dictum. praesent nunc ipsum, id mattis odio. donec rhoncus posuere bibendum. fusce nulla elit , laoreet non posuere. if text, script should select lorem, aliquam, varius , elit thanks in advance you can this, using javascript wrap every word in paragraph in own span, , walking through spans finding out actual position on page is, , applying style changes spans y position greater preceding span. (best beginning-to-end, though, earlier ones may affect wrapping of latter ones.) it's going lot of work browser, , you'll have repeat each time window resized, effect have worth cost. something (used jquery you've listed jquery tag on question , makes code lot simpler):

i have 2 transaction scopes, 1 within another. love know if inner transaction scope rolled after has been committed , outer 1 not complete. since nested, inner transaction roll back. this not whole story, , depends on how create nested transaction, default, roll back. this article goes depth transactionscope , should answer of questions. being distributed or not irrelevant.

things aware of: screen flicker if scripts alter styles / content (not issue me load scripts @ end of page , have workarounds already) inability detect script load failure (not too concerned either develop required work or without javascript. might affect workarounds item 1 happy risk) it looks option me hoping references (feel free positive things!) before invest time in incorporating next project. currently develop mid-to-large sized sites with, generally, moderate amount of javascript (although growing rapidly). use jquery library bulk of our javascript. anyone have experience? or bad! :) p.s. interested this head.js nope. long put code dependent on loading files inside head.ready {} not face problems code.

i' change value of dom element according user-defined specification. let's want multiply 100. specification should defined in ff preferences. the path of least resistance seems to take value of element , 'action: "*100"' in preferences , use eval value. however, eval evil , believe not safe (someone replace '*100' function etc.). so, can think of way avoid using eval , still read format preferences somehow?

if have number of classes like @property (nonatomic, retain) nsstring* mystring; and want access property in object 1 of these classes (but don't know type id), "request member 'mystring' in not structure or union" error. so if each of these classes conforms : @protocol myprotocol <nsobject> @required @property (nonatomic, retain) nsstring* mystring; @end then cast property: (id<myprotocol>)anobject.mystring why doesn't work? still same error. in case prefer messages-sending notation on dot-notation, shows clearly, when cast happen: these lines equal: [(id<myprotocol>)anobject mystring] ((id<myprotocol>)anobject).mystring and these are: (id<myprotocol>)[anobject mystring] (id<myprotocol>)anobject.mystring

is there possibility disable session warnings being displayed when php cli script run? without modyfing php.ini of course. need have clean output of script. script not run apache or root. in php.ini there session.auto_start enabled. i've got following errors: php warning: unknown: open(/var/lib/php/session/sess_p6tpcdkpupelvho22qrkm699g4, o_rdwr) failed: permission denied (13) in unknown on line 0 php warning: unknown: open(/var/lib/php/session/sess_p6tpcdkpupelvho22qrkm699g4, o_rdwr) failed: permission denied (13) in unknown on line 0 thanks in advance! quite simple, don't try open session in cli mode. won't work multiple reasons. so, 2 things (depending on how "dirty" of hack wanted): if (!isset($argc)) { //not cli session_start(); } or, set session path writable (like /tmp ) if via cli: if (isset($argc)) { session_save_path('/tmp'); } but i'd suggest not suppressing errors ( error_reporting(0) ) because mak

i have created application in php , jquery of display locations on google map. there few images in divs after clicking on there 3 ajax requests called in following order 1: display video youtube 2: display description database. 3: display locations on map. after clicking on images in div, result displayed in following order. 1: display description database. (it displayed within 1 sec) 2: display locations on map. (it displayed within 2 sec) 3: display video youtube. (it displayed within 2 sec 3 sec) as map , youtube video not located on local server, taking time display. there way display above 3 output when data receive servers?

i'm new android development , have question regarding overlays in googlemaps api. what i'm trying achieve class adds 1 , 1 marker @ position tap, want overlay active when button "add marker" pressed. i've solved problem in 2 different ways , i'm not satisfied either 1 of them. my solutions follows: first attempt: bool turns true when "add button" pressed, able put marker on map , boolean value turns false. this feels quite ugly , overlay active , listens every tap on display, maybe is't dumb believe. second attempt: temporary creates overlay creates marker , removes self. this solution can't find efficient... creating new overlay before creating new marker. is there way activate overlay when "add button" pressed? maybe there other way this? is there way activate overlay when "add button" pressed? don't add overlays list until add button pressed.

is possible set or override default state structure? as example have an enum something{a,b,c,d,e}; and structure links 2 values enum struct somethingdata { type; int value; double multipler; somethingdata(something enumval, int intval, double dblval) {...} } but can specify default state is somethingdata(something.c,0,1); struct constructors similar class constructors, except following differences: structs cannot contain explicit parameterless constructors. struct members automatically initialized default values. struct cannot have initializer in form: base (argument-list). http://msdn.microsoft.com/en-us/library/aa288208(v=vs.71).aspx so, short answer, no can't override default constructor (every struct has parameterless constructor , can't hide or override it)...
