c# - How to adjust zoom level on windows phone 8.1 map by pushpins -

-

i working map control in windows phone 8.1(rt) application , have 2 custom push pins on map , 1 in source address , second destination address , want change zoom level according both push pins , means both pins display on screen path current zoom level 

 maplocation.zoomlevel = 14;

i want change zoom level according both location

you can calculate boundaries of multiple pushpins(positions)in winrt using geoboundingbox.trycompute , set map's view these boundaries.

        try         {         geopoint sourcepoint = --source point here--;         geopoint destpoint= --dest point here--;                  //calculate boundries                 var locations = new list<basicgeoposition>();                 locations.add(sourcepoint.position);                 locations.add(destpoint.position);                 var boundries = geoboundingbox.trycompute(locations);                 await smapcontrol.trysetviewboundsasync(boundries, new thickness(100), mapanimationkind.none);         }         catch(exception)         {             // ignored         }

note second parameter trysetviewboundsasync method margin added around calculated boundaries.

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
