i'm trying understand ways in c global variable can shared between multiple files (compilation units). i've read excellent question , answer here . after doing few tests i'm still left stuff don't get: basically question be: if there's variable declared (but not defined) in header without extern keyword, ok include header in various compilation units in order make available variable compilation units? in scenario it's implied 1 (and one) compilation unit contains code initializing (defining?) variable, , called first before other compilation units try variable. if true, procedure what's called "implicit extern" ? i'll illustrate question example: header "mycommonheader.h" contains: //mycommonheader.h int* i; //pointer int file myfirstheader.h contains: //myfirstheader.h void changeit(int newvalue); file myfirstsource.c contains: //myfirstsource.c #include "myfirstheader.h" void changeit(int newvalue) {...

[uiview animatewithduration:1.0f animations:^{ self.settingspanel.frame = cgrectmake(self.settingspanel.frame.origin.x, self.settingspanel.frame.origin.y, self.settingspanel.frame.size.width, self.settingspanel.frame.size.height + 300); }]; frame external coordinate. when change frame, change actual position of view...

i experimenting 2 dimensional array of classes in java. wrote following (wrong) code: public class gameevent { static int launch_alien = 0; static int end = 1; long time; long cum_time; int alien_type; int event_code; } then gameevent[][] event_array = new gameevent[max_levels][max_events]; and accessed code below (read comment in code): event_array[lev][ctr].event_code = code; // nullpointer exception @ runtime so question is, least painful way change code works. gameevent[][] event_array = new gameevent[max_levels][max_events]; this allocates array of references gameevent objects not objects themselves. to allocate obects necessary every cell of array: for (int = 0; < max_levels; ++i) (int j = 0; j < max_events; ++j) event_array[i][j] = new gameevent();

i can click on node select it, marks node selected. multi select works great well. i can drag selected node(s) however, without above mentioned selection dragging node not select (.bind("select_node.jstree", function (e, data) fires on mouseup) if have nodes selected , drag node ; these selected nodes not deselected. basically,how emulate windows explorer drag , drop functionality ? to deselect selected nodes, call function before selecting current node. $("#tree").jstree("deselect_all"); call above function , go on selecting current node followed code. cheers!

i know hashtable synchronized, whereas hashmap not. as per knowledge synchronization means accessing object @ time 1 thread. so there no problem while using hashtable. in project using hashmap. used in many places. till did not problem hashmap. so when synchronization concept come picture(i.e using hashmap). can use hashmap in places using hashtable? can use hashtable in places using hashmap? so there no problem while using hashtable not - in situations, hashtables require external synchronization (for example while iterating). when synchronization concept come picture (i.e using hashmap)? if have class holds hashmap: public class someclass { private map map = new hashmap(); } and access map several threads, might unexpected behaviour , should use adequate synchronization. as long access map single thread or local variable within method, fine. can use hashmap in places using hashtable? cf. above: yes if map not accessed seve...
