i've been researching on topic before implementing it. thing is, mine music player app i'm making widget, control music playback. wanted put seekbar in widget that's not supported. progressbar supported there hardly widgets use one. i'm skeptical of how using progressbar effect user's phone's performance (in terms of battery life , memory usage). since progressbar meant display current position of music playing, have updated every second. read here progress bar in appwidget playback service updating widget's progressbar every second bad idea. post more 4 years old. couldn't find newer. question is, still bad idea use progressbar , updates every second, in app widget? or have latest android updates brought in new ways efficiently? if yes, how go it? any guidance helpful. question is, still bad idea use progressbar, updates every second, in app widget? in general, bad idea update app widget every second, regardless of whe

in bootstrap have fixed top nav bar , fixed bottom nav bar. want show large image in background between space of 2 nav bars , want cover width of window. how can dynamically height between navbars , width of window? window size may change depending on device.so need dynamic $(window).resize(function() { var top_nav_height = $("#id_of_top_nav").height(); var bottom_nav_height = $("#id_of_bottom_nav").height(); var window_height = $(window).height(); var height_of_open_space = window_height - (top_nav_height+bottom_nav_height); $("#id_of_img").css({ height:height_of_open_space+'px'; }); }); this fine if 0px padding , margin, if not values , subtract height_of_open_space before applying img height

how find id of dynamically created radio groups , each radio button have 4 radio buttons you can set id every view setid(int) , search it. remember put in layout views without same ids.

i'm not sure if it's possible @ wonder if it's possible bind text box 2 different fields depending on value of third. suppose have carrier goes origin destination , has status of being on way or having arrived. because of business logic , way customer works want grid of orders this. #id orgin dest. status 101 b going 102 c d going 103 d going however, when order id e.g. 102 reaches status, point of destination should viewed in origin column , destination column should empty (or show next stop or whatever else), this. #id orgin dest. status 101 b going 102 d - done 103 d going so bind column origin field origin in data context if status going bind field destination if status done . if it's not possible, how can approach it? forced create new data type maps actual orders viewable orders? or add property view model isn't supported field rather renders value depending on status? here exa

i've searched , searched, seen bits of code looks solution, doesn't work. i'm not experienced in use of regular expressions , see i'm doing wrong here. string line = input.replace("<td>", ";"); string withouttabs = regex.replace(line, "\t", ";"); string withouttd = regex.replace(withouttabs, ".*</td>", ";"); the code above trying replace of <td> </td> , tabs html table layout. doesn't work, doesn't remove tabs nor replace </td> tags. </td> tag attached text, this: text</td> i want this: text; could point out mistake, or regex wrong , need replace else? i want replace <td> </td> , tabs ; regex.replace(input, @"</?td>|\t", ";"); demo

i have several markers on google maps , in each marker listview several entries. each entry can liked user , if has liked, there stored entry in sqlite database marker id, entry id , if has liked (1) or took (0). want filled heart shown below each list item user has liked. problem is: if there many entries, there randomly filled hearts, if user liked 1 entry. can figure out mistake? activity, saves in sqlite database if entry saved: getallentryslistview.setonitemclicklistener(new adapterview.onitemclicklistener() { @override public void onitemclick(adapterview<?> parent, view view, int position, long id) { try { jsonobject entryclicked = jsonarray.getjsonobject(position); entryid = entryclicked.getstring("id"); } catch (jsonexception e) { e.printstacktrace(); } likebutton = (imageview) view.findviewbyid(r.id.heartimage);

hello work on game based on map generation bing. the problem is: card generated based on address given user, after generate 1km2 card (1000m wide , 1000m long). unfortunately found no bing api retrieve map defined size in meters. can define "level zoom" , resolution. here's use (from microsoft bing api tile code library example): bing maps tile system // bing map (resolution max. 834 pixel) zoom level 16 var stream = await httpclient.getstreamasync("api/newmap/?latitude=46.6052284&longitude=7.0967002&mapsizeheight=834&mapsizewidth=834&zoomlevel=16"); // calculated "latitudecentre" , "zoom level" , 0.8 meter/pixel double meterperpixel = tilesystem.groundresolution(latitudecentre, 16); for example (834/834 pixel) , zoom level 16 => gives me scale of 0.8 meter / pixel. can not generate 1 meter / pixel map. think solution problem exist? i hope if yes ^^ :-) ok , yes it's possible !! take time

i've asked question ( multiple errors while momoizing function inside function ) , i've got nice answer... but! understand little more javascript, i'd know if momoized function can written in style: function main () { function memoized_f(){ //memoizing code } } edit: please notice i'm not asking difference in code above, i'm asking if possible memoize second one! so, how rewrite this? function main() { var create_node = (function() { var memo; console.log("memo: " + memo); console.log("create_node") function f() { var value; if (memo) { value = memo.clonenode(); console.log("clone node"); console.log(value); } else { var value = document.createelement("div"); value.innerhtml = "hello"; console.log("new node"); console.log("value: " + value); memo = value; } r

i trying replace file in resource folder (src/main/resources) new file generated gradle build script. i'm having trouble doing this; exclusion seems remembered, , preventing addition of new file. here's short example illustrates behavior. project structure: testproject -- src/main/java ---- entry ------ entrypoint.java ---- run ------ helloworldtest.java -- src/main/resources ---- test.properties // file replace test.properties contents in src/main/resources: wrong file text make obvious 1 being put jar based on size build.gradle: apply plugin: 'java' task makeprop { def propdir = new file(builddir, "props") ext.propfile = new file(propdir, "test.properties") outputs.file propfile dolast { propdir.mkdirs() propfile.createnewfile() propfile.withwriter('utf-8') { writer -> writer.writeline 'right file' } } } jar { dependson('makeprop')

i specify azure automation job once ie "scale db1 standard s2 using credential - mycredential". have provide these parameter values every time set new schedule. there seems no concept of creating specific job , specific schedule , linking 2. yes link jobs schedules, schedule can take 1 job, have unlink schedule first before being able link job. i guess desired relationship is: job -< jobschedule>- schedule and have job -< schedule. but job can defined when setting schedule. i job list like: jb-weekdaynightscaledownqav11 jb-weekdaynightscaledownqav12 jb-weekdaymorningscaleupqav11 jb-weekdaymorningscaleupqav12 jb-weekendstartscaledownqav11 jb-weekendstartscaledownqav12 for schedules want: sch-weekdaymorning sch-weekdaynight sch-weekendstart having defined these 9 objects, edit them individually without affecting of others. linkages might like: sch-weekdaymorning -jb-weekdaynightscaledownqav11 -jb-weekdaynightscaledownqav12 however fear n

i know powershell doesnt have goto statements. have requirement follows: foreach($x in $xyz) { #something works fine if($a -eq $b) { #something works fine if($c -eq $d) { $c | add-content "path\text.txt" }else { #here need go first if statement, rather going foreach loop } }else { #nothing } } have tried break :---- , functions both doesnt seems work in case. when use break :----, notifies error in last else. when try use function below: foreach($x in $xyz) { #something works fine function xyz { if($a -eq $b) { #something works fine if($c -eq $d) { $c | add-content "path\text.txt" }else { xyz } }else { #nothing } } } it not entering function xyz. any other suggestions achieve this.? appreciated. i think want nested loops: foreach ($item in $data) { while (condition $data) { # stuff, calculate $state if (othercondition($state)) { # w

i calling c++ function c# using p/invoke, function has infinite loop (capturing frames file) should broken when event happened in c#. how can break loop (which terminates function)? i tried run function in thread in c#, , abort thread when termination needed. but abort function didn't work . thread thread = new thread(mymethod); thread.start(); // terminate function thread.abort(); //didn't respond probably safest way 2 things: expose function named (eg) stoprecording sets global variable inside native code inside main function, check value of global @ start of every loop iteration see if stoprecording has been called (and if so, break out of loop) this lets terminate naturally without requiring heavy-handed terminations.
