i ran trouble pygame while making character move on screen through path on grid. collecting dirty rects .update() method not taking account updates whole screen. happens on 1 loop inside main game loop. structure this: while not done: other stuff if character should move: step in path: while not in target: update coordinates couple pixels blit , collect dirty rects update(dirty_rects) #this 1 still updates whole screen update(dirty_rects) #this 1 works correctly, updating dirty places so inner loop moves character according steps in path given, , game goes main loop. problem is, inner .update() draws whole screen again if give tiny rect rect(0,0,10,10) input. outer .update() works fine. situation destroys framerate when character moving. takes around 70ms between each frame while outer loop takes around 5ms. there can it? i using python 3.4.2 on os x, updated 3.4.3 no effect. e: tried inst

when style background of body element, why styling affect entire screen , not body element itself? let's create following rule: body {width: 700px; border: 1px dotted red; background-color: blue;} i find border shows 700px wide expect, background color occupies entire browser viewport. why? quote http://www.w3.org/tr/css21/colors.html the background of root element becomes background of canvas , covers entire canvas, anchored (for 'background-position') @ same point if painted root element itself. root element not paint background again. the body element root-element, , thus, required css rules loses background style , background style applied containing canvas (the webpage area in browser), therefor entire screen blue. other properties stay element (e.g. border ).

i have set of ids in c# datatable. @ same time, have table containing ids , other data too. requirement delete records contains ids specified in data table ( if there tuples ids). i'm using sqldataadapter that. sqlcommand command = new sqlcommand(text, con); command.updatedrowsource = updaterowsource.none; preparecommand(command, con, null, type, text, commandparas); sqldataadapter adpt = new sqldataadapter(); adpt.deletecommand = command; adpt.updatebatchsize = 2; adpt.update(datatable); connection.close(); here mean by, - "text" name of stored procedure containing delete command. argument given stored procedure id ( picked list of ids contained in data table) - "commandparas" argument passed stored procedure. - "datatable" contains ids used delete rows sql table. contains 1 column several rows. but not result in specified rows being removed table. edit i have given stored procedure below create procedure somename(@id int

when attempt create sortable list html5 drag n drop, target of drop event ( e.target ) child of drop-zone element, rather drop-zone element itself. bad. i want value of e.target in following code div contains ondrop="drop(event)" rather it's <p> child. link jsfiddle full example. function drop(e) { e.preventdefault(); var data = e.datatransfer.getdata("text"); e.target.appendchild(document.getelementbyid(data)); } is happening because of event bubbling, or similar? best fix me create drag n drop sortable list? edit: looking understand native html5 , javascript, not use jquery library or such. you trying append target element, hence facing problem. you should try insert element before target element. function drop(e) { e.preventdefault(); var data = e.datatransfer.getdata("text"); var list = document.getelementbyid("list"); list.insertbefore(document.getelementbyid(data), e

say have implicit class like: implicit class richstring(str: string) { def sayhello(): string = s"hello, ${str}!" } we can use method sayhello if defined on string class "world".sayhello does scala compiler optimize static call avoid overhead of constructing richstring object? scala compiler optimises method call if specify class extends anyval. these called value classes. example docs, link given below: class richint(val self: int) extends anyval { def tohexstring: string = java.lang.integer.tohexstring(self) } http://docs.scala-lang.org/overviews/core/value-classes.html

if create statement jdbc , execute query, need close said statement , create new 1 before executing again? eclipse doesn't complain second case. try { connection = datasource.getconnection(); try { statement = connection.createstatement(); statement.execute("set search_path '...'"); } { utils.tryclose(statement); } try { statement = connection.createstatement(); statement.execute("set statement_timeout " + (query_timeout_seconds * 1000)); } { utils.tryclose(statement); } try { statement = connection.createstatement(); statement.execute(query); } { utils.tryclose(statement); } } { utils.tryclose(connection); } as opposed to: try { connection = datasource.getconnection(); statement = connection.createstatement(); statement.execute("set s

i've been trying @ properties of slider in wpf imitate slider zoom of powerpoint, can't find way imitate it. in powerpoint, min value = 10 , max value = 400. center value equal 100. in slider in wpf, if min value = 10 , max value = 400. center value not 100. evenly distributed. not in powerpoint. you have idea on how imitate powerpoint zoom slider? i guess this topic you're looking for. put slider this: <slider name="myslider" minimum="0.1" maximum="2" value="1" largechange="0.1" smallchange="0.01" tickplacement="both" ticks="0,0.5,1,1.5,2"/> and e.g. square myslider.value desired zoom factor.

i have code this: class foobar { private string statefoo; public foobar(string statefoo){ this.statefoo = statefoo; } public void foo() { fooinst f = fooinstfactory.createsomefooinst(anotherstaticfooconfig.getsomepath); f.justcountme(); } } my goal make sure f.justcountme() executed once. know how in general mockito. don't know how inject mocked version of fooinst foo method? can count invocation? is possible so? if possible; suggest avoid using mocking libraries temper static fields (in way powermock/mockito do) - comes undesired side effects (for example many "coverage" tools produce invalid results when static mocking takes places). so suggestion: re-design class under test. instead of fetching f static factory; provide constructor either factory or f; can mock corresponding object; without need turn mighty dangerous "powerxyz" stuff.
