i have program written in c allows user scroll through display of zillion small files. each file needs undergo amount of processing (read only) before it's displayed user. i've implemented buffer preprocesses files in radius around user's position, if they're working linearly through them, there's not delay. various reasons, can run processing algorithm on 1 file @ time (though can have multiple files open, , can read them) buffer loads sequentially. processing algorithms optimized they're going get, i'm running i/o problems. @ first, loading process slow, when files have been accessed few times, speeds 5x. therefore suspect what's slowing me down waiting windows page cache pull files memory. know little sort of thing. if ensure files in cache before processing algorithm needed them, i'd in business. my question is: there way persuade/cajole/trick/intimidate windows loading files page cache before around reading/processing them? ...

in c, arrays passed functions pointers. structures can passed functions either value or address (pointer). there specific reason why can not pass array value can pass structre value ? in c, everything passed value. there rule says in contexts, name of array equivalent pointer first element. passing array function such context. so, special case not arrays passed reference, special case the rule arrays decaying pointers . gives 1 impression array passed reference (which is, know why!) the post in link above explains in more detail type of array in different contexts.

i have noticed in chrome . has idea what's wrong or workaround ? you can use setinterval instead - keeps on running. if need one-shot solution, use clearinterval delete timer. setinterval fire if computer asleep while event should have been fired. tested behavior in chrome, firefox , internet explorer. example, have @ http://blaeul.de/de/content/javascript-timer-test , source.

gwt doesn't serialize java date properly. when tried sending date created in javascript through wire, found out dates between april 1st (funny) , 25th october years before year 1983 subtracted 1 day. that means that, say, both 1982-04-01 , 1982-03-31 become 1982-03-31 on java side. given dates in question, guess kind of dst problem. i've tried googling, , found one other reference describes similar problem. i tried submitting bug gwt team, curiously wasn't able find bugtracker gwt. so, questions are: anyone else run this? i'm on gwt 1.7, , confirm if happens on 2.0 well. my workaround send dates strings, , parse them on server. knows better workaround? assuming using java.util.date question 1: seems fixed in 2.0. i've created both dates above (1982-04-01 , 1982-03-31) , come through correctly server (both represent on server 1982-04-01 , 1982-03-31 respectively). setup is: gwt 2.0 java 1.6 osx 10.6.2 question 2: pass 'milliseco...

i initialising user prefs , setting , getting numeric prefs not seems able , set string prefs. prefs initialise not altered later on in gadget, int prefs are. i set user pref set actual value prefs.set("cpopup8_value",popup8_value); later in app value can changed but when accessing later still original default value popup8_value = prefs.getstring("cpopup8_value"); i have checked writing correct value seems case , have checked have not exceeded 2k limit. storing , retrieving integers works fine.

i wanna save state of qcheckbok in qsetting, can cast value int maybe exists more simple , proper method it? here code: qsetting setting; qt::checkstate checkstate; //... checkstate = (qt::checkstate)setting.value("checkstate", qt::unchecked).touint(); //... setting.setvalue("checkstate", (uint)checkstate); setting.sync(); firstly, try avoid c-style casts. example, replace following line: checkstate = (qt::checkstate)setting.value("checkstate", qt::unchecked).touint(); with this: checkstate = static_cast<qt::checkstate>(setting.value("checkstate", qt::unchecked).touint()); the line cast checkstate uint should changed. secondly, qsettings relies on qvariant setting , retrieving values. qvariant can expanded support additional types using q_declare_metatype macro. here's documentation: http://doc.trolltech.com/4.6/qmetatype.html#q_declare_metatype however, mechanism not appear work enumerations (when ca...

on compilation code: struct any_type: boost::tuple<std::string, std::string, std::string> { ... }; struct functor { void operator()(const std::string& v) { std::cout << v << std::endl; } }; int main() { any_type type; boost::fusion::for_each(type, functor()); } get error: no type named 'category' in 'struct any_type' why? want inherit boost.tuple. inherit boost::fusion::tuple instead of boost::tuple . note: consider making void operator()(const std::string& v) const

there bunch of different logging libraries choose from, each own set of quirks , advantages. (.net examples: log4net, system.diagnostics.tracesource, nlog, etc.) the natural inclination abstract away quirks , use logging facade. (examples: castle.services.logging , common.logging , simple logging facade ) way, if given logging framework you're using goes stale, or different 1 comes vogue, can swap out implementation , leave code untouched. but there multiple logging facades choose from. given answer many disparate logging implementations abstraction, why not use logging facade facade? if sounds ridiculous, makes more ridiculous original logging facade? makes 1 layer of abstraction on top of logging framework magic number? i speak perspective of using abstraction insulate application code particular logging framework. there other factors can affect one's choice of logging framework or one's choice of (and requirements for) abstraction. i have spent lot of...

folks, i have asp.net project pretty n-tier, namespace, need separate 3 projects: data layer, middle tier , front end. i doing because... a) seems right thing do, and b) having sorts of problems running unit tests asp.net hosted assemblies. anyway, question is, keep config info? right now, example, middle tier classes (which uses linq sql) automatically pull connection string information web.config when instantiating new data context. if data layer in project can/should using web.config configuration info? if so, how unit test, (typically in separate assembly) provide soch configuration info? thank time! we keep them in global "settings" file happens xml. file contains global settings, 1 of connection string pointing appropriate server username , password. then, when applications consume it, put specific catalog (database) need in connection string. we have version of file each operating environment (prod, dev, staging, etc). then, 2 setting...

this super urgent! need vpython working, can give me on way this? i'm running on mac os x python 2.6 , , downloaded vpython. upon installation installs boost libraries python. now, when try import vpython libraries ('visual'), following occurs: >>>import visual traceback (most recent call last): file "<stdin>", line 1, in <module> file "/library/frameworks/python.framework/versions/2.6/lib/python2.6/site-packages/visual/__init__.py", line 59, in <module> import cvisual attributeerror: 'boost.python.staticproperty' object attribute '__doc__' read-only after reading around i've found possibly serious bug, lack technical know-how implement (or indeed trust myself try , implement) of 'workarounds' posted on interweb. does know decent fix this? or walk me through (newbie style) how implement of fixes. i believe have installed latest boost libraries svn trunk, although (very unhelp...

my application needs 2 com dlls registered. done automatically if user has necessary access rights, otherwise can done using regsvr32 . now on few workstations following happens: start cmd.exe administrator register first dll: success register second dll: failure (0x80004005, access denied) the first time error reported me, automatically responded: "of course doesn't work, need administrator privileges." needless say, felt pretty embarrassed tried register dll myself... what reason this: 1 dll can registered, other not. some background information: both dlls created delphi 2005. both dlls have simple interfaces , few classes. the failing machines vista or windows 7. normally i'd start process monitor, don't have access 1 of workstations right now, have gather information possible until can hands on 1 of them. update : remotely accessed 1 of failing workstations. mysterious things happened: starting process monitor not possible (!) a...
