i know can dump values of excel cells array so: object[,] values = worksheet.usedrange.value2 object[,]; can similar attributes of cells other values? example, i'd cell colour, object[,] cc = worksheet.usedrange.interior.color object[,]; results in cc being null. looping through sheet cell attributes takes orders of magnitude longer. better late never. briefly, in absence of code stub, save sheet xml formatted file. read file in xml reader, query xml object styleid (or else want or need). query styleid's color attrbiute, , match same each cell. linq queries on xml database should need couple of lines this.

i read 2 articles @ http://preshing.com/20120305/implementing-a-recursive-mutex http://en.wikipedia.org/wiki/reentrant_mutex on recursive(reentrant) mutex, neither article made sense. could explain how recursive(reentrant) mutex works ? (i found little material explaining how recursive mutex works. if has link explanation, close question.) thanks ! one simple way pair standard mutex following auxiliary information: a pointer thread owns mutex (or null if it's not acquired), and a counter, 0. you can acquire mutex in following way: if current mutex owner, increment counter , return immediately. if not, acquire mutex , set counter 0. in other words, if own mutex already, increment counter indicating own more. if not, acquire mutex usual. you can release mutex in following way: if counter nonzero, decrement counter , return immediately. otherwise, release mutex. in order work, need able read counter , mutex owner in thread-safe way. can

has occurred simple std::cout might print value in hex format when supposed format decimal(like integer)? for example, have line : std::cout << "_agent [" << target << "] still among " << ((target->currworker)->getentities().size()) << " entities of worker[" << target->currworker << "]" << std::endl; which print : _agent [0x2c6d530] still among 0x1 entities of worker[0x2c520f0] note: 1-the said out put sometime decimal , times hex 2- behaviour smae if change ((target->currworker)->getentities().size()) (int)((target->currworker)->getentities().size()) any hints? thanks you have set std::cout print hex in prior in context of code forget reset. example: std::cout<<std::hex<<12; /*blah blah blah*/ std::cout<<12; //this print in hex form still so have following std::cout<<std::dec<<12; to print in d

shouldn't able entitykey object using complex property method or property method dbentityentry. couldn't find examples msdn , presume possible in entity framework 5. not know name of entity key or entity using generic repository interface. if have dbentityentry object entitykey first finding wrapped objectcontext : var oc = ((iobjectcontextadapter)dbcontext).objectcontext; then can find entity key by oc.objectstatemanager.getobjectstateentry(dbentityentryobject.entity) .entitykey edit i created 2 extension methods close want: public static entitykey getentitykey<t>(this dbcontext context, t entity) t : class { var oc = ((iobjectcontextadapter)context).objectcontext; objectstateentry ose; if (null != entity && oc.objectstatemanager .trygetobjectstateentry(entity, out ose)) { return ose.entitykey; } return null; } public static entitykey getentitykey<t>( dbcontext c

i searched , tried days. problem this: i wrote script load shared library locker.so , runs lua interpretor, can not write out correct host program. my lua script load_so.lua simple: locker = require("locker") print(type(locker)) k, v in pairs(locker) print(k, v) end my host program is: int main(int argc, const char *argv[]) { lua_state * l = lual_newstate(); lual_openlibs(l); if (lual_dofile(l, "load_so.lua") != 0) { fprintf(stderr, "lual_dofile error: %s\n", lua_tostring(l, -1)); lua_pop(l, 1); } lua_close(l); return 0; } when run host program, error print out: lual_dofile error: error loading module 'locker' file './locker.so': ./locker.so: undefined symbol: lua_pushstring and locker.c: static int elock_get(lua_state * l) {...} static int elock_set(lua_state * l) {...} static const struct lual_reg lockerlib[] = { {"get", elock_get}, {"set"

i have <?php $attr = array( 'title' => 'here title', 'alt' => 'here alt attribute' ); ?> div class="s-o-column"> <div class="s-o-thumb"><a href="<?php echo $termlink; ?>"><?php echo wp_get_attachment_image( $term->image_id, 'standard-options-thumb', false, $attr ); ?></a> <div class="s-o-title"><a href="<?php echo $termlink; ?>"><?php echo $term->name; ?></a></div> </div> </div> how change title , alt say; <?php the_title(); ?> instead of "here title" or "here alt attribute"? you should use get_the_title() instead of the_title() since get_the_title() returns title while the_title() echoes it. $attr = array( 'title' => get_the_title(), 'alt' => 'here alt attribute&

when take picture, save image file in folder made in nsdocuments directory. (/documents/photos/....png) then load photos in photo's folder in collection view. since files big, decided use grand central dispatch perform grabbing image on background thread. when scroll , down uicollectionview can see images changing randomly before displaying correct image. assume whenever grab image set on main thread, don't know how deal this. - (uicollectionviewcell *)collectionview:(uicollectionview *)cv cellforitematindexpath:(nsindexpath *)indexpath { nsuinteger rownumber = [indexpath row]; //nsstring *imagepath = [self.photopatharray objectatindex:rownumber]; nsarray *directorycontent = [[nsfilemanager defaultmanager] contentsofdirectoryatpath:[[nshomedirectory() stringbyappendingpathcomponent:@"documents"] stringbyappendingpathcomponent:@"photos"] error:null]; nsstring *imagepath = [nshomedirectory() stringbyappendingformat:@"/docu

is there way determine whether process has died? have system service stores information on each client connects it. when process hosting client dies, clean cache. i've searched on google seems not possible :( one solution came across using binder's linktodeath, design not mesh current design. there alternative ? thanks the state of thread can determine using isalive() method thread, or use getstate() determine thread state more precisely. binder has method isbinderalive(), didn't use can't add uncovered in officical docs.
