Firemonkey (Delphi XE5) Android Altitude from GPS -


trying gps altitude on android device using delphi xe5/firemonkey.

... var   altdbl  : double; ...    sender tcustomlocationsensor     begin     //did bypass possible problem tostring conversion     altdbl := altitude;     lbaltitude.text := formatfloat( '###0.0## meters', altdbl );      lblatitude.text := latitude.tostring();     lblongitude.text := longitude.tostring();     end;

the lat , lon work altitude returns "nan".

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
