how show mask , turn on msb of 8 bit integer? have tried different logical opeartors not getting right answers if have 8 bit integer turning msb set '1' bit 7. so mask 0x80 (only bit 7 on). in order set bit can use bit-wise or | : #define msb_mask 0x80 // or #define msb_mask (1 << 7) int x; x = x | msb_mask; // or x |= msb_mask; make shorter

the expression #define __hi(x) *(1+(int*)&x) is defined in sun's math library , in fdlibm.h . used in programs of sun's math library, e.g., in its implementation of sin(x) double y[2],z=0.0; int n, ix; /* high word of x. */ ix = __hi(x); /* |x| ~< pi/4 */ ix &= 0x7fffffff; if(ix <= 0x3fe921fb) return __kernel_sin(x,z,0); in code above, variable x of type double. can 1 explain me syntax expression in __hi(x) . the readme of sun's library says __hi(x) "the high part of double x (sign,exponent,the first 21 significant bits)". i not understand syntax of *(1+(int*)&x) , , why corresponds x 's higher part. clarification? this: *(1+(int*)&x) means: take address of x ( &x ), cast pointer-to-int (int*) , add 1, , dereference resulting pointer. assuming sun using this format , means value in memory looks like: <sign (1 bit)><exponent (11 bits)><significand ...

i have service working in background - service a . when open activity - activity a , want service change text displayed on edittext field of activity a . thought maybe if context of opened activity able use , work on views. possible? also related question: if don't have name of field, can use loop run , search views in activity , properties? it seems less direct method preferred getting this, rather have activity directly updated service. in fact, in general service/activity communications best handled in 1 of following ways: messagehandlers- basically, 1 can send message other, in turn other sets actions of text. broadcastreceivers (localbroadcastreceiver okay)- 1 part sends broadcast message listening, other sets listener message. intent passed, can contain message. i suggest use second. application sends broadcast service upon opening, , service returns broadcast pass requested data activity. see service docs android sdk.

i tried creating regular expression verify path names filesystem api write using gridfs. my current regex ^[a-za-z0-9\-\[\]()$#_./]*$ can fulfill criteria: allow a-z , a-z , 0-9 , -[]()$#_./ however doesn't meet these additional criteria: first character has / there mustn't occurrence of multiple / in row. questions: can me fix regex? are there possible issues using criteria path names? (did miss important?) not sure path criteria, regarding regexp, pretty simple: ^\/(?!\/)([a-za-z0-9\-\[\]()$#_.]|(\/(?!\/)))*$ \/(?!\/) means slash / not followed slash (?!\/) . used twice, once first character, , again 1 of possible matches after first character.

i developed web application using java spring mvc. want deploy application on tomcat server , want application run in period of time in day. say, application run 10:00 6:00 pm everyday , other time of day application cannot used. have searched if can done tomcat server 6 want deploy application unable solution or clue how achieve purpose. so, question how can implement wanted do? solution, samples or ideas helpful complete task. i think trying solve problem using infrastructure instead of using application should solved.if requirement not have application available during period of time, business requirement, code solution it. example not allow logins if login falls outside specified time period , instead display message user. existing sessions intercepted using handler , invalidating session forcing re-login. another solution run cron job on server, stops tomcat @ specified time , starts again. not advisable users not know of operating times , assume wrong.
