windows phone 7 - Push Pin not locating in bing maps -

-

the push pin tool not finding location when provide value manually (latitude , longitude).

here code:

double dbllat = 13.060407;  double dbllong = 80.249562;  pushpin mypin = new pushpin();  watcher = new geocoordinatewatcher(geopositionaccuracy.high);              watcher.movementthreshold = 40;              watcher.start();              watcher.position.location.latitude = dbllat;              watcher.position.location.longitude = dbllong;              mypin .location.latitude = dbllat;              mypin .location.longitude = dbllong;              //credentialsprovider cp=              map1.center = new geocoordinate(mypin.location.latitude, mypin.location.longitude);             map1.setview(mypin .location, 5.0);             push.tag = "location";             push.content = "i'm here";             map1.children.add(mypin);             watcher.stop();

what doing wrong?

if thats error:

one or more waypoints can't routed because far roads.

try

geocoordinate loc = new geocoordinate(dbllat, dbllong); mypin.location = loc;

instead of 

mypin .location.latitude = dbllat; mypin .location.longitude = dbllong;

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
