this question has answer here: activity restart on rotation android 28 answers so first app on android , it's working great. however, when tilt screen horizontal view integers reset zero. if start horizontally switch vertical, resets integers 0 too. how can not reset , switch? override onsaveinstancestate(bundle outstate) method. put data in outstate bundle, , then, in oncreate(bundle savedinstancestate) , extract savedinstancestate . if data more complex trivial integer, , not implement parcelable interface, use fragment .

i want learn opengl development , running linux mint. khronos.org says following: the opengl 4.4 , opengl shading language 4.40 specifications released on july 22, 2013. as far understand mesa opengl implementation linux 1 version 3.1 believe. question is, can develop opengl 4.4 apps in linux environment or have use mesa's 3.1 version? you can develop opengl 4.4 software #including glext.h file http://www.opengl.org/registry/ you can run opengl 4.4 software using hardware drivers implement opengl 4.4 specification , gpu supports necessary hardware features. in practical terms, means need amd or nvidia gpu supports direct3d 11 , recent proprietary (closed-source) drivers gpu vendor. mesa3d open-source driver framework, partial support opengl 4.x. proprietary drivers amd , nvidia replace mesa3d own opengl implementation. note can develop opengl 4.4 software if system cannot run said software.

i trying kinds of ways make .sort() work on csv dataset. no luck. for starts, i'd sort data "value" column. this function i'm running inside d3.csv api call , before select dom , append divs: dataset = dataset.sort(function (a,b) {return d3.ascending(a.value, b.value); }); before .sort , clean data: dataset.foreach(function(d) { d.funded_month = parsedate(d.funded_month); d.value = +d.value; }); }; everything seems in order. when console.log(d3.ascending(a.value, b.value)) , right outputs: -1 d32.html:138 1 d32.html:138 -1 d32.html:138 1 d32.html:138 etc.. yet bars data doesn't sort. what's wrong? it not clear provided code hazard guess not handling async nature of d3.csv. this plunkr shows sort code working fine . note data object declared, populated, , used. here partial listing. have added buttons re-order data . achieve need put ordering logic inside render rather inside d3.csv

clustered indexes physically order data on disk. say have table employee , columd employee_id. store values 9, 6, 10, 4 under employee_id. clustered index on employee_id. values on disk stored in sorted fashion i.e 4, 6, 9, 10. if search on employee_id id 9, database can use search algorithm binary search or other quick spot record id 9. possible not fine record in 1 operation binary serach. is correct? non clustered index non-clustered index has duplicate of data indexed columns kept ordered pointers actual data rows (pointers clustered index if there one). if take same example above. in case database create separate object store data along memory location.something this 9 -- phyical location 6 -- phyical location 10 -- phyical location 4 -- phyical location so first need search 10 in newly created object , memory location. go orginal memory location. so how come makes search faster ? also per understanding, index should created on column involved under cl

a small hiccup led me basic question. intend check class equivalence in following case (academic curiosity - please not direct me instanceof or isinstance ): public class staticchild extends staticparent{ .... public static void main(string[] args){ staticchild thisobj=new staticchild(); system.out.println(thisobj.getclass()==staticparent.class); } } this gives compilation error: error: incomparable types: class<cap#1> , class<staticparent> system.out.println(thisobj.getclass()==staticparent.class); cap#1 fresh type-variable: cap#1 extends staticchild capture of ? extends staticchild what mean? what difference between type , class(specifically context - type , class of staticchild)? how rid of compilation error? since thisobj declared of type staticchild , expression: thisobj.getclass() returns object of type class<? extends staticchild> . trying compare object of type class<staticpar

i have mysql table contains index id, data entry , 10 other columns called peso1, peso2, peso3...peso10. im trying last 7 peso1 values specific id. like: $sql = mysql_query("select * table id='$id_a' order data desc limit 0, 7"); when try fetch values mysql_fetch_array, values together. example: while($line = mysql_fetch_array($sql)) { echo $line['peso1']; } i peso1 values 7 days together. how can separated? they appear because not separating them loop through them. for example, insert line break , see them on separate lines while($line = mysql_fetch_array($sql)) { echo $line['peso1'] ."<br />"; } you key array so $myarray = array(); $i = 1; while($line = mysql_fetch_array($sql)) { $myarray['day'.$i] = $line['peso1']; $i++; } example use $myarray['day1'] // returns day 1 value $myarray['day2'] // returns day 2 value

for exercise in accelerated c++ i'm implementing custom string class called str . worked fine when underlying storage container custom vector ( vec ) i've run weird situational problem don't understand. if create new str object explicitly calling constructor str newstr("some words"); , try overwrite using cin >> newstr; program crashes in end, giving sigabrt in debugger when reaches str destructor (which delete[] data; ). this doesn't happen if create new, empty str use cin fill str newstr; cin >> newstr; , or if use cin overwrite str made using str newstr = "some words"; , fails when attempt overwrite str made explicitly calling non-default constructor though type displays correctly before being overwritten. another weird thing in case works fine if don't create new str s between creating/displaying odd-behavior str , using cin change value. str = "here a"; str b("and here b"); cout <<

the long double data type can have these conversion specifiers in c: %le,%le,%lf,%lg,%lg ( reference ). i wrote small program test : #include <stdio.h> int main(void) { long double d = 656546.67894l; printf("%.0le\n",d); printf("%.0le\n",d); printf("%.0lf\n",d); printf("%.0lg\n",d); printf("%.0lg\n",d); return 0; } output: -0 -4e-153 -0 -4e-153 -4e-153 but none giving desired output, 656547 (as may understand). reason? the compiler used gcc version 3.4.2 (mingw-special). from old mingw wiki : mingw uses microsoft c run-time libraries , implementation of printf not support 'long double' type. work-around, cast 'double' , pass printf instead. example: printf("value = %g\n", (double) my_long_double_value); note similar problem exists 'long long' type. use 'i64' (eye sixty-four) length modifier instead of gcc's

my goal annotate plot slope of best-fit line , label units of slope, label saved separate string object. i'm having trouble figuring out how bquote() convert string object expression, , combine other evaluated statements. a demonstration: # example data: x <- c(1:20) # x units: time y <- x * rnorm(20, 10, 2) # y units: length per time unit.label <- "l%.%t^-2" # label slope of best fit line lm1 <- summary(lm(y ~ x)) plot(y ~ x) the problem occurs when try annotate plot. can bquote() display slope: text(median(x), min(y), bquote(slope: .(round(lm1$coefficients[2], 2))) ) i can bquote() show slope's units: plot(y ~ x) text(median(x), min(y), bquote(.(parse(text = unit.label))) ) but i'm unable combine label , slope single bquote() statement: plot(y ~ x) text(median(x), min(y), bquote(slope: .(round(lm1$coefficients[2], 2)) .(parse(text = unit.label))) ) # error: unexpected symbol in "text(media

i need read microsoft excel 2003 file (.xls) query in sql server 2005, , insert of data tables. reading file , using data not problem in itself, found that, column, null value instead of value that's shown in excel file. more specific: column 1 character long, , can contain 1 digit 0-9, or letter 'k'. it's when column contains 'k' query gives me null value. assumption that, since first few rows contain numbers values of column, query assumes numbers, , when finds letter turns null. i tried changing format of cells in excel file text, , using cast , convert (not @ same time) on value try make varchar, nothing. that looks older ole db driver excel. not doesn't work--you can still "query" spreadsheet it. maybe try newer: select * openrowset('microsoft.ace.oledb.12.0', 'excel 12.0 xml;hdr=yes;database=c:\file.xls', 'select * [sheet1$]') you'll need updated odbc driver on sql se

i need scan wifi networks. how can getrssi() of wifi scan network (not of connection wi-fi network) int level = wifimanager.calculatesignallevel(wifi.getconnectioninfo().getrssi(), results.get(i).level); int difference = level * 100 / results.get(i).level; ok try find signal strength wifimanager manager; manager = (wifimanager) getsystemservice(wifi_service); list<scanresult> results = manager.getscanresults(); int level = getpowerpercentage(results.get(0).level);//0 first scan result , on. method find signal stength public int getpowerpercentage(int power) { int = 0; int min_dbm = -100; if (power <= min_dbm) { = 0; } else { = 100 + power; } return i; } hope ll you.

i working on drawing graphs our data. there no problem on drawing graph basically. problem flags information not loaded , located on graph lines. let me give issues on it. data cannot brought graph if has on 900 numbers of items. one data might have more 4000 items. instead using 1 big data, tried spilt 1 data small pieces of data. each piece of data has 800 items, , intended being loaded on graph sequentially. however, process not done well. sometime graph module cannot load every piece exactly. moreover, process take time using 1 data. i wonder whether appropriate way load flag data contains many items exits or not. $(function() { var report_data; $.ajax({ type: "post", url:"/apps.chart/chart.reportshort", data:"callback=?&report_type=co&business_code=005930", datatype:"json", success:function(report){ report_data = report; } }); $.getjson(&

i trying retrieve data leave_balance.php , pass employee.php , data null. here script leave_balance.php : if($lid=="1") $bal = $bal + $replacementleave; here script employee.php : $bal = $rowe[bal]; then call $bal on html page: <input type='text' value='$bal'> can help? thank you. you can't directly use $bal otehr file. instead can use session variables . this- employee.php: session_start(); $_session['bal']= $rowe[bal]; leave_balance.php: if($lid=="1") $_session['bal'] = $_session['bal'] + $replacementleave; also, cannot use php variable inside html directly. use php var inside html text- <input type='text' value="<?php echo $_session['bal']; ?>"> or, can echo html statement- echo "<input type='text' value='".$_session['bal']."'>";
