i'm maintaining long living app on android, , i've decided change data model behind merging few sqlite databases single new one. the thing is, if create new db , stop using old ones, every app user out there still have old sqlite files in local storage. is there way force "clear data" upon new version of app? (i'm looking "right" way it, know can check if new db exists , act according, think there may better way) thanks whenever database needs upgraded(when user downloads new version of app, example), change in database version number calls onupgrade() method, can override thiis method provided sqliteopenhelper class: @override public void onupgrade(sqlitedatabase db, int oldversion, int newversion) { log.w("taskdbadapter", "upgrading version "+oldversion +" "+newversion +", destroy old data"); (string string : table_names) db.execsql("drop table...

i have topicentity contains many postentity . each postentity belongs 1 topicentity . need sort topics last post creation date, creationdate property of newest post in topic. what think needs happen: get topics join posts belong topic sort posts creation date get newest post each topic , use date sort topics this have currently: this.session.createcriteria(topicentity.class, "topic") .createalias("topic.posts", "post", criteriaspecification.left_join) .addorder(order.asc("post.creationdate")).list(); this not sort topics in way. believe because not perform points 3 , 4 list. anyway, hint me proper way of achieving desired result? prefer criteria, if hql required, that's fine.

i collecting data light sensor amount of time: msensormanager.registerlistener(this, lightsensor, sensormanager.sensor_delay_fastest); the problem values collected not accurate , frequent. "not accurate", mean if start sensor @ time, first reading old 1 of long before began collecting data. also, since delay declared sensormanager.sensor_delay_fastest , lot of values , sometime 100s of records in 1 second , sometime not 1 reading in 3 seconds. can explain issue might , if there solutions please? i believe because these light sensors send data when there change in light. not readings if light level not change, if wave hand in front of or turn dimmer switch slowly, 100s of readings.

i'm using following queries produce 2 forms, each displaying half of items in table. selects top half: select top 50 percent * products order products.product_id; and selects bottom half select top 50 percent * products order products.product_id desc; the obvious problem when items odd, middle item displays on both forms. tried solving using count() function in various ways not work top. how else can this? ignore odd number of rows issue when define first half. define second half rows not present in first half. use subquery in() , left join approach faster. select secondhalf.* products secondhalf left join ( select top 50 percent product_id products order product_id asc ) firsthalf on secondhalf.product_id = firsthalf.product_id firsthalf.product_id null; the subquery, firsthalf , same first query in question. in situation, need product_id subquery. left join in main query means return rows products ......

i implementing program using hadoop. question how deal java out of space problem, added property configuration xml file, didn't work. increasing number of reducers doesn't work me either. because in program every reducer needs large sparse whole matrix, , not allowed change logic. yet every reducer receive entry column id key, , column vector value.is there way can out of dilemma? ps:i first thinking reducer take column 1 one, , won't cause out of memory issue. seems not way. actually, trying implement algorithm described in paper. algorithm reducer listed below. line 11 column mentioned, , each reducer has every column of matrix. the reason why use hadoop because cant fit entire data set memory. either don't change logic , try find computer that's big enough or parallel-ize algorithm , exploit hadoop.

i have set of variables represent prices , number of items sold in 2d array. have sorted in order find lowest price. i'd set second variable (number sold) of first item (player a) value (200) referring array. for example: var playerasold; var arr=[ [playeraprice,playerasold], [playerbprice,playerbsold], [playercprice,playercsold]]; arr[0][1]=200; this doesn't work, because playerasold has value of 0 , trying set 0=0. how refer variable , not value of variable? javascript has no notion of c's pointers or c++'s references, you'll have in different way. rather trying store references in array, try making array sole holder of data. might this: var players = [ { price: 5, sold: 1 }, { price: 3, sold: 6 }, { price: 9, sold: 2 } ]; then rather than, say, playerbsold , can use players[1].sold . can use variable in place of 1 if wanted.

i'm new wpf. windows forms , datagridview can force user stay in edit mode if value entered in grid not valid (for example when entering letters in column valuetype set double) code this: datagridview grid = new datagridview(); grid.dataerror += (sender, e) => { }; i'm trying have similar behavior wpf datagrid no luck. tried following binding options: datagrid.columns.add(new system.windows.controls.datagridtextcolumn() { header = "aheader", binding = new system.windows.data.binding("aproperty") { validatesondataerrors = false, validatesonexceptions = false } }); but can't see change @ all. entering non valid data causes app crash. idea please?

i have gameobject want animate along specific path/curve, animation should controlled mouse/touch position. when touch/click on gameobject , move finger/mouse on/near path (or maybe easier move down) gameobject should follow defined path. i itween, think not possible find solution using here, right? edit: added image: it's quite simpler task might think. basically it's question of remapping function (that takes input parameter) function (that express position along path). there several ways of doing that, depending on precise effect want implement. the important choices have take are: how describe path/curve how handle input example for path easy , flexible way use sort of spline curves, such cubic bézier curve . it's easy implement , unity3d provides built-in functions draw them. have @ handles.drawbezier . basically bézier function takes input parameter t in domain [0,1] , return result point in space (2d or 3d prefer). b(0) gives point...

i need match js: a number, which potentially can followed letter (or two), and may separated space or hyphen for example: 23 4545a 1b 554 cs 34-s regex not strong suit, i've got this... ^[0-9a-za-z ]+$ updated: ^(0-9a-za-z )+$ aaaaand, mine hybrid of other answers. :) /^\d+[ -]?[a-z]{0,2}$/i \d+ = 1 or more digits [ -]? = optional space character (note: space only, not "whitespace") or dash [a-z]{0,2} = 1 or 2 alpha characters (note: lowercase @ moment, keep reading . . .) the i @ end of pattern makes case insensitive, [a-z] match upper or lower-case alphas edit - okay, found error in of our answers. lol because alpha pattern allow 0 characters @ end , space , dash optional, regexes we've provided far result in false positive following test data: 123- , 456 <--- space @ end the second 1 resolved using $.trim() on value (if allowed trying test), first 1 can't. so . . . brings new regex handle situat...

i have 2 methods take string , remove 'invalid' characters (characters contained in hashset). 1 method uses linq.where, uses loop w/ char array. the linq method takes twice long (208756.9 ticks) loop (108688.2 ticks) linq: string linq(string field) { var c = field.where(p => !hashchar.contains(p)); return new string(c.toarray()); } loop: string chararray(string field) { char[] c = new char[field.length]; int count = 0; (int = 0; < field.length; i++) if (!hashchar.contains(field[i])) { c[count] = field[i]; count++; } if (count == 0) return field; char[] f = new char[count]; buffer.blockcopy(c, 0, f, 0, count * sizeof(char)); return new string(f); } my expectation linq beat, or @ least comparable to, loop method. loop method isn't optimized. must missing here. how linq.where...
