i have tabhost 2 tabs in it. first time switch second tab onresume() method of second's tab's activity invoked. have alertdialog shown , after disappears 'onresume()' method isn't called wait it. presume invocation of 'alertdialog' triggers 'onpause()' method , 'onresume()' should called before 'activity' shown , ready interaction user. in face 'onpause()' isn't called when switch first tab activity . can advice why 'onpause()' , 'onresume()' methods aren't called , methods called after showing 'alertdialog' or switching between tabs ? i presume invocation of 'alertdialog' triggers 'onpause()' method , 'onresume()' should called before 'activity' shown , ready interaction user alertdialog not affect activity's life cycle. check out activity's life cycle flow chart here. when switching between tabs, if want call method why do...

here 2 ways of comparing 2 datetimes: datetime = datetime.now; datetime = new datetime(2008, 8, 1); // method 1 if (datetime.compare(then, now) < 0) // ... // method 2 if (then < now) // ... .compare returns integer (-1,0,1) indicating whether first instance earlier than, same as, or later second instance. my question is, why use .compare when can use relational operators ( < , <= , == , >= , > ) directly? seems me, using .compare , need employ relational operators anyway (at least in above example; alternatively create switch statement examining cases -1, 0 , 1). what situations prefer or require usage of datetime.compare() ? typically, .compare methods on types used sorting, not doing direct comparisons. the icomparable<t> interface, when supported on type, allows many framework classes sort collections correctly (such list<t>.sort , example). that being said, if want able comparison within generic class or method,...

as understand, using structure value types give better performance using reference types in array or list. there downside involved in using struct instead of class type in generic list? ps : aware msdn recommends struct should maximum 16 bytes, have been using 100+ byte structure without problems far. also, when maximum stack memory error exceeded using struct, run out of heap space if use class instead. as others have pointed out, there many downsides using large structures in list. ramifications of others have said: say you're sorting list members 100+ byte structures. every time items have swapped, following occurs: var temp = list[i]; list[i] = list[j]; list[j] = temp; the amount of data copied 3*sizeof(your_struct) . if you're sorting list that's made of reference types, amount of data copied 3*sizeof(intptr) : 12 bytes in 32-bit runtime, or 24 bytes in 64-bit runtime. can tell experience copying large structures far more expensive indirection inhe...

in vs2010 ultimate edition if hand --standalone flag f# compiler in projects pane not link empty c# project configuration files/resource files it will, however, link assembly if explicitly declare --staticlink:config this feels bug...if intentional, may ask why be? this expected behavior: the standalone flag statically links fsharp.core.dll (f# runtime) , reference assemblies depend on (i.e. other f# assemblies). need linked because may share types primary assembly (e.g. f# list type etc.) the staticlink flag links assembly explicitly specify (and assemblies depend on it). means can use option link, example, c# library main f# assembly references. i think 2 cases handled separately, because inlining f# runtime requires special handling (almost f# code uses in way, , compiler treats differently)

when create or open file in unix using o_creat flag, st_mtime , st_ctime , st_atime of file changes. when create or open file using o_trunc flag, st_mtime , st_ctime changes , not st_atime . from understanding, st_atime changes when file accessed. when open or create file using o_trunc flag, not accessing file? this question bit old, answer future generations @ least... from stat(2) man page (on host linux 2.6.32 kernel): the field st_atime changed file accesses, example, execve(2), mknod(2), pipe(2), utime(2) , read(2) (of more 0 bytes). other routines, mmap(2), may or may not update st_atime. the field st_mtime changed file modifications, example, mknod(2), truncate(2), utime(2) , write(2) (of more 0 bytes). moreover, st_mtime of directory changed creation or deletion of files in directory. st_mtime field not changed changes in owner, group, hard link count, or mode. the field st_ctime changed writing or set...

i have segmented control following code in action method: -(ibaction)togglecontrols:(id)sender{ if([sender selectedsegmentindex] == kswitchessegmentindex){ leftswitch.hidden = no; rightswitch.hidden = no; dosomethingbutton.hidden = yes; } else{ leftswitch.hidden = yes; rightswitch.hidden = yes; dosomethingbutton.hidden = no; } } however, when run program i'm getting error kswitchessegmentindex . it's saying kswitchessegmentindex undeclared identifier. can me what's wrong here? you have show kswitchessegmentindex being defined. convention define variables like: #define kswitchessegmentindex 1 or, define int: int kswitchessegmentindex = 1; since shouldn't need change value first choice might best. example: #include <avfoundation/avfoundation.h> #define kmyconstant1 0 #define kmyconstant2 1 @implementation myclass

in windows it's possible increase size of on-screen fonts. realized late , if user our programm unusable because can not see texts , controls. we're bringing out release , not have time fix that. so: how can disable or ignore increasing windows application-wide? tried setting autoscale none not working. isn't possible ignore setting whole application? how can that? know week solution because user has reason why wants increase font size. can not fix problem within 2 weeks want provide application can work. thanks help ps: use vb.net according microsoft workaround is: right-click shortcut, click on compatibility tab , tick "disable display scaling on high dpi settings" (although doesn't seem work.)

dear c++ professionals. got problem. have program, has 1 abstract class base_class , 2 derived classes: sippeers , dbget. has 2 threads. first thread gets commands user, second thread pocesses these commands. both derived classes represent different commands. so, have create kind of stack, should put user commands first thread , them in second thread process. make 1 stack commands, got use polymorphism. first, tried use std::list. there first problem: can't make list of abstract classes. tried use boost::ptr_list, there second problem: classes, created in first thread, dissappear end of procedure, created them. pointers become illegal. question: kind of realization should use? looks must store every copy of derived class. where? an std::queue of shared_ptr<base_class> straightforward solution pass classes 1 thread without worring memory management. combined conditional variable signal queue not empty, consumer-thread can wait. for polymorphism part, have virt...

we use template toolkit in catalyst app. configured tt use utf-8 , had no problems before. now call substr() method of string var. unfortunately split string after n bytes instead of n chars. if n 'th , (n+1) 'th byte build unicode char split , 1st byte part of substr() result. how fix or workaround behaviour? [% string = "fööbär"; string.length; # prints 9 string.substr(0, 5); # prints "föö" (1 ascii + 2x 2 byte unicode) string.substr(0, 4): # prints "fö?"
