i can contact number phone. want know how remove country code it. if user has phone number country code(+91-9876543210), need phone number without prefixed country code(9876543210). thanks in advance. i'd suggest use libphonenumber parse phone numbers easily. can split country code , phone number in way. try { // phone must begin '+' phonenumberutil phoneutil = phonenumberutil.getinstance(); phonenumber.phonenumber numberproto = phoneutil.parse("+91-9876543210", ""); int countrycode = numberproto.getcountrycode(); long nationalnumber = numberproto.getnationalnumber(); log.i("code", "code " + countrycode); log.i("code", "national number " + nationalnumber); } catch (numberparseexception e) { system.err.println("numberparseexception thrown: " + e.tostring()); }

i have step in script in vb6 failing. code follows output = ((azmnum + steps ) mod 16777216) the values variables in function -850344 = (5184326 + -6034670) mod 16777216) all variables long numbers. other programs enter these values (python , excel) return 15926872. can't figure out why modulo being ignored. mod not same in languages, negative numbers. vb6 (and whole load of other compilers c, c++, c#, java) takes fortran interpretation remainder after dividing. mathematically, wrong interpretation if number negative. have is 5184326 + -6034670 = -850344 -850344 mod 16777216 = -850344 python , excel take correct interpretation of modulo result positive. takes step i.e. -850344 + 16777216 = 15926872

problem: you given array m of size n , each value of m composed of weight w , , percentage p . m = [m 0 , m 1 , m 2 , ... , m n ] = [[m 0 w , m 0 p ], [m 1 w , m 1 p ], [m 2 w , m 2 p ], ..., [m n w , m n p ] ] so we'll represent in python list of lists. we trying find minimum value of function: def minimize_me(m): t = 0 w = 1 in range(len(m)): current = m[i] t += w * current[0] w *= current[1] return t where thing can change m ordering.

so have google api project. i've written c# program connect using public access api key. when api key not restricted particular ip address, program works. however, when restrict api key ip address of server, so: i ip blocked error, so: i confirmed ip of machine in 2 ways. went whatsmyip.com , got this: and wrote little php program on server , called via console app remote_addr: according every method know check, ip address ###.###.###.197. when put ip in key server applications says ip not allowed. i've run same program other computers , put computers' ip addresses in server key , program worked. why google api not recognizing ip address of machine @ ###.###.###.197 though permitted ip in api key? one idea: can modify google api project tell client ip address google sees? have never worked google api saw can geolocation , stuff that, assume google-side code should able access info. if google api project sees .197 ip address, it's time conta...

how can redirect specific url appear in url parameter? example: http://www.mywebsite.com/code_id.tv/stream.php i want code_id , redirect specific url. the result url this: http://www.mynewwebsite.com/tv.php?id=code_id thanks to split path code_id: var url2process = window.location.pathname; var patharray = url2process.split( '/' ); // remove '.tv' or '.movie' or '.whatever' end var code_id_array = patharray[1].split('.'); var code_id = code_id_array[0]; // redirect window.location = 'http://domain.com/rb/play.php?id=tt' + code_id;

for ios app working on, need manage controls displayed on screen based on type of device app running on. i try explain theoretical example (the actual numbers used below not important, interests me best method achieve desired result). example: in case of app in screenshots, button overlaps uiimageview should not displayed @ or displayed in place on screen. so far i've worked autolayout , , figure, there's no way xcode like: hey, class size "compact width / compact height" , want hide these buttons...but show them "regular width / compact height" . i did googling , saw people talk using different storyboards based on device; thinking, add/remove buttons dynamically based on device type , think it's not pleasant have add of constraints hand (programatically is). so resume, appreciate suggestion of 'best' way , best meaning combination of 'not hard' + ' not long'. also, code example (or links) highly appreciated. ...
