it seems me if startactivity called implicit categoryless intent, activities intent filter specifying default category (android.intent.category.default) can launched. the category not needed in intent filter services if use startservice instead of startactivity. does see same behavior ? is documented somewhere in android official documentation ? i think documented. see http://developer.android.com/reference/android/content/intent.html : the categories, if supplied, must listed activity categories handles. is, if include categories category_launcher , category_alternative, resolve components intent lists both of categories. activities need support category_default can found context.startactivity(). my experience category-less activity can used startactivity() if class explicitly set in intent, though. in case, no intent matching done.

i trying implement variadic function. searched web , ended finding out examples handle 1 type of arguments (for example calculating average of many integers). im case argument type not fixed. can either involve char*, int or both @ same time. here code ended : void insertinto(int dummy, ... ) { int = dummy; va_list marker; va_start( marker, dummy ); /* initialize variable arguments. */ while( != -1 ) { cout<<"arg "<<i<<endl; /* or c here */ = va_arg( marker, int); //c = va_arg( marker, char*); } va_end( marker ); /* reset variable arguments. */ now work okay if had deal integers see have char* c variable in comments use in case argument char*. so question is, how handle returned value of va_arg without knowing if int or char* ? since you're doing c++ there's no need use untyped c-style variadic function. you can define chainable method like class inserter...

in carbon change window's visibility hidewindow(windowref) , showwindow(windowref). in cocoa know can call nswindow's orderout: hide , orderfront:, orderback: or orderwindow:relativeto: put on screen, none of respect ordering of window relative other windows when last visible. for example, if have 2 windows, 1 above other, , call orderout: on window, how show window again such still behind front window without calling orderwindow:relativeto: . the thing can think of right remember window id of window above , use orderwindow:relativeto: when showing again, haven't thought through happens if window above closed before rear window made visible again. i don't think there's method available in cocoa. guess need mimic using idea. by way, carbon behavior if start 4 windows ordered as b x c d e then hide x b c d e now user reorders them, , removes some: e c and show x again. did x go in carbon in case?

our group has main site , subsite dedicated our projects. each project has project lead , completion % associated it. have list on project site goes each project's dedicated subsite within project site. want duplicate list project site on main site, changes or additions made project site list appears in main site list including project lead , completion %. how accomplish this? here simple example of hierarchy: main site - project list derived project list below project site - project list project 1 site project 2 site project 3 site what want approach similar one suggested in previous question. now, question linked reverse of situation: person wanted copy information master site onto of child sites. incorporating in reverse work well, need flip logic. basically, instead of attaching these event handlers master site, attach them project list site, , updates passed master site instead of iterating across of subsites.
