i building n-tier application have wcf service (not data / ria services) hosted on web project on iis server, , windows phone client service reference pointing on wcf service. my wcf service access database through entity framework. here problem : when update database anywhere client, update cannot seen in clients. when update database specific client, modifications can seen him. but after while, clients have access updated data. i believe can caused iis caching of wcf's datas, or caching @ linq level, problem remains after disabling iis caching. any idea on how fix this? thanks so turn in formal anwer: the framework attempt cache values (not iis). so, ensure not extending unit of work beyond scope of transaction (i.e. using both same , retrieve method(s)). also, try re-establishing context between store/retrieve calls should remove existing caching may occurring within framework. i.e. [operationcontract] public void save(myobject entity) { using (my...

i'm new cloud computing , vm thing. have vps 768mb ram (1gb burstable), when check dashboard processing, see average usage 178mb , maximum 618mb. what happen if run same script on vps, vps has 64mb. kill process? or use virtual memory disk space? the script in php, , crawling web pages , saves text. it may kill process , set off alarms, or go swap (which slow entire system down , noticeable anyways); it's hard say, depends on host's configuration. if host though, , ended using ram on vps that's supposed have just 64mb, you'd have account terminated entirely.

sometimes little confusing me keep in mind upperbound for loop excluded default. there way make inclusive? yes, for in range(upper + 1) or if like, for in range(lower, upper + 1) work, a lot of programming languages use zero-based indexing, non-inclusive upper bound common practice (this due memory addressing , adding offset) just example: if had array of size 5, ar , starting index 0 , your largest valid index value 4 (i.e., 0, 1, 2, 3, 4), loop construct refer size of array (5) so: for in range(5): or more common , better: for in range(len(ar)): .. ensuring legal index values 0 .. 4.

take program (adapted exploratory test-case, noticed custom metatype bahaves if registered, although qregistermetatype had not been called): #include <qmetatype> #include <qvariant> #include <iostream> class c1 { }; q_declare_metatype(c1) int main() { std::cout << qmetatype::type("c1") << std::endl; qvariant v = qvariant::fromvalue<c1>(c1()); std::cout << qmetatype::type("c1") << std::endl; return 0; } this outputs: 0 256 (and further tests show metatype indeed registered -- can construct 'ed (even in places q_declare_metatype(..) not visible), etc) is behaviour well-known? relied on? (probably not, attempting failing test following "official" rule register metatype first got me puzzled, hence question) p.s. of course, 1 can see qregistermetatype called within q_declare_metatype(..) , question still holds (at least to). thanks in advance. q_declare_met...

relatively simple question, not 1 i've found exact answer - let's have cpan'd mongodb driver, set db data, , want capture results of find text string manipulate in perl script. use mongodb; use mongodb::database; use mongodb::oid; $conn = mongodb::connection->new; $db = $conn->test; $users = $db->x; $parseable; #ran in mongoshell earlier: db.x.insert({"x":82}) $string = $users->find({"x" => 82}); @objects = $string->all; print "len: ".(@objects.length())."\n"; #returns 1....hmmmm...would imply has entry! print @objects[0]."\n"; print $objects[0]."\n"; print keys(@objects)."\n"; print keys(@objects[0])."\n"; print "@objects[0]"."\n"; these output following on command line, none of them wanted )-=: len: 1 hash(0x2d48584) hash(0x2d48584) 1 2 hash(0x2d48584) what want bson string - want mongoshell returns in string in perl! dream output followin...

i trying use "file size" (aka "filesizedisplay") in calculated column formula. "file size" existing column (default sp not custom). not available in "insert column" list of library. , sp displays error message states not exist if added formula manually either [file size] or [filesizedisplay]. all want inform user image big. not trying prohibit file size upload or technical that. want calculated column display message. if column value available following work: =if([file size]>50000,"image big","image sized correctly") or =if([filesizedisplay]>50000,"image big","image sized correctly") any 1 know why column not available? cheers you'll want file size first: get file size can display of message in pop or how ever you'd like using system; using system.io; class program { static void main() { // name of file const string filename = "test.txt"...

i've written python script using pylab , scipy output hierarchical cluster heatmaps , dendrograms expression matrix based on post: plotting results of hierarchical clustering ontop of matrix of data in python now export array , gene (column , row) dendrograms text files such program treeview can view data (e.g., cdt, gtr, atr files). have experience this? thanks

when debugging application see messages time: an exception of type 'xxxx.xxxxx' occurred in xxxxx.exe not handled in user code. the problem have backgroundworkers throw exceptions in dowork, these handled checking runworkercompletedeventargs.error in runworkercompleted event - , works great @ runtime. is there way prevent visual studio showing these "unhandled"? is not correct way return errors dowork ui? i tried making exception extend applicationexception , unticking box next applicationexception in exceptions dialog still shows up. you need catch , handle exceptions inside methods dowork method calls. recommendation catch exception , use reportprogress event report interface smooth handling/notification. don't ever want "swallow" exception, reporting allow gracefully log exception or notify user in less intrusive manner. keep in mind, you'll need to use overload of reportprogress allows use of custom userstate can e...

so, title pretty expresses confusion. looking recommendations online or in book form learn how use visual studio and/or other software accomodate updates and/or version control of custom programs write work. i assistant, , 1 within our 3 man department, programming experience. have written number of custom programs on years accomplish specific goals existing data. however, limited experience programming (3 years aas degree in focus on programming) , little exposure other programmers advice (basically none said, no 1 in 3 man office knows programming) leaves me these questions. as being realized can produce things in-house benefits many, skills being put more use (and 1 welcome , enjoy it....not knock admins, heart lies in programming). however, issues still lie on how use visual studio create programs, in future need update class here or there, or function within class.... any references books or articles appreciated!

i'm having trouble deciding should go in particular dimension , should go in fact table star schema i'm developing. for sake of example, let's project keeping track of houses property management company. dimensions various dates, renter, contract, etc. straightforward. house, no matter data lives, want keep track of current owner, current renter, current rental contract, things neighborhood, address, current rental price, current market value, , forth. note owner, renter , contract dimensions (and neighborhood , address may dimensions, don't care much). a lot of data kept houses used in filtering queries, or row , column headers of cube. of needed ancillary information, looked @ on house house basis, not in aggregate. given data, , need it, have (at least) 3 options: dimhouse: house table dimension, lot of attributes might better in fact table, since used browsing , filtering, need here. snowflaking/outriggers required attributes current renter. facthouse...

when performing query in mongodb, need obtain total count of matches, along documents limited/paged subset. i can achieve goal 2 queries, not see how 1 query. hoping there mongo feature is, in sense, equivalent sql_calc_found_rows, seems overkill have run query twice. great. thanks! edit: here java code above. dbcursor cursor = collection.find(searchquery).limit(10); system.out.println("total objects = " + cursor.count()); i'm not sure language you're using, can typically call count method on cursor that's result of find query , use same cursor obtain documents themselves.
