java - File isDirectory() method always returns false when folder name contains special chars -


i false return isdirectory() method when folder name contains specials chars ó or ñ.

the java code works fine in dos, have problem executing jar in nas (linux).

public static void listardirectorio(file f, string separador)         throws exception {      file[] ficheros = f.listfiles();     file ficherotratado = null;      (int x = 0; x < ficheros.length; x++) {          ficherotratado = null;         ficherotratado = ficheros[x].getcanonicalfile();          if (!ficherotratado.isdirectory()) {             system.out.println(                     "checking file: " + ficherotratado.getname());             if (esborrable(ficherotratado.getname())) {                 system.out.println(                         "file can erased: " + ficherotratado.getname());             }         }else if (!ficheros[x].getname().startswith("@")) {              string nuevo_separador;             nuevo_separador = separador + " # ";             listardirectorio(ficheros[x], nuevo_separador);         }     } }

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...
