now use android studio instead of eclipse, hope can control if need save file, seems android studio save file automatically. after try close modified file window, hope android studio can display prompt dialog , let me choose if save modified file. how can do? thanks! android studio based on jetbrains intellij idea platform takes full control on when files saved. options controlling file save found in appearance & behavior > system settings > synchronization section of settings. these not require. many people switching alternative ide's have same concerns you. in discussions can find there no way around this. the jetbrains developers argue because platform has built in local history differences file saves, possible rollback file saves. read more jetbrains developers here: https://devnet.jetbrains.com/docs/doc-191 here similar discussion on issue intellij ide: intellij - not asking if want save file

do write specific exception s error responses of apis use? e.g.: class smsserviceexception extends exception { } class smsservicesendexception extends smsserviceexception { } is there specific built in exception in php situation? there 1 invalid arguments invalidargumentexception . you're go when comes exception. php has native exceptions these not refer non-built-in php problem. it quite common mistake miss argument, throw exception php needs when doing own things, creating classes can freely create exceptions since many of ideas not have default exception in php. you on other hand write exception class entire api , pass in name of module edit exception creating 1 "flexible" exception. make abit less readable code tho keep in mind ;)

i have code , when executes, throws nullreferenceexception , saying: object reference not set instance of object. what mean, , can fix error? what cause? bottom line you trying use null (or nothing in vb.net). means either set null , or never set @ all. like else, null gets passed around. if null in method "a", method "b" passed null to method "a". the rest of article goes more detail , shows mistakes many programmers make can lead nullreferenceexception . more specifically the runtime throwing nullreferenceexception always means same thing: trying use reference, , reference not initialized (or once initialized, no longer initialized). this means reference null , , cannot access members (such methods) through null reference. simplest case: string foo = null; foo.toupper(); this throw nullreferenceexception @ second line because can't call instance method toupper() on string reference pointing null .

i have 2 tables, same column named user_name, saying table_a, table_b. i want to, copy table_b, column_b_1, column_b2, table_b1, column_a_1, column_a_2, respectively, user_name same, how in sql statement? as long have suitable indexes in place should work alright: update table_a set column_a_1 = (select table_b.column_b_1 table_b table_b.user_name = table_a.user_name ) , column_a_2 = (select table_b.column_b_2 table_b table_b.user_name = table_a.user_name ) exists ( select * table_b table_b.user_name = table_a.user_name ) update in sqlite3 not support clause, makes little more work in other rdbms. if performance not satisfactory, option might build new rows table_a using select , join table_a temporary table. delete data table_a , repopulate temporary.

this question has answer here: naming conflict built-in function 7 answers so tried "evil" thing ned deily mentioned in answer here . have type true false. how reverse within interactive window? thing not do: true = false since true has been overridden false, there doesn't seem obvious way back-track. there module true comes can like: true = <'module'>.true you can del custom name set default: >>> true = false >>> true false >>> del true >>> true true >>>

i've been trying play animated gif using tkinter.photoimage , haven't been seeing success. displays image, not animation. following code: root = tkinter.tk() photo = tkinter.photoimage(file = "path/to/image.gif") label = tkinter.label(image = photo) label.pack() root.mainloop() it displays image in window, , that's it. i'm thinking issue has tkinter.label i'm not sure. i've looked solutions tell me use pil (python imaging library), , it's don't want use. with answer, created more code (which still doesn't work...), here is: from tkinter import * def run_animation(): while true: try: global photo global frame global label photo = photoimage( file = photo_path, format = "gif - {}".format(frame) ) label.configure(image = nextframe) frame = frame + 1 except exception:

i'm working out codeeval problem gives me array of strings. each string has 4 integer values represent 2 points on cartesian grid so, 'a, b, x, y', may same. objective determine relative direction of second point in relation first point , express relationship in conventional orienteering terms, e.g., n, ne, e, ..., nw. if points identical, return here. i able solve problem ok, , core of function here var ary = line.split(' '), direction = '', dif_long = ary[2] - ary[0], dif_lat = ary[3] - ary[1]; if (dif_lat !== 0){direction = (dif_lat > 0) ? 'n' : 's';} if (dif_long !== 0){direction += (dif_long > 0) ? 'e' : 'w';} if (direction == '') {direction = 'here';} console.log(direction ); i've put sample data on js fiddle , modified generate list rather console.log. my problem got 0 points solution. leads me think have performance problem somewhere. appreciat
