if use following line: shutil.copyfile(r"\\mynetworkshare\myfile.txt","c:\temp\myfile.txt") everything works fine. however, can't seem figure out how use variable network share path, because need 'r' (relative?) flag. end result imagine like: source_path = "\\mynetworkshare" dest_path = "c:\temp" file_name = "\\myfile.txt" shutil.copyfile(r source_path + file_name,dest_path + file_name) but have had no luck different variations of approach. the r used in first code example making string "raw" string. in example, means string see backslashes , not try use them escape \\ \ . to second code sample working, you'd use r on strings, , not in copyfile command: source_path = r"\\mynetworkshare" dest_path = r"c:\temp" file_name = "\\myfile.txt" shutil.copyfile(source_path + file_name, dest_path + file_name)

need post data static html page page hosted on domain. i'd create , iframe form inside of post method, , actions directed web page, , submit form. complexity i'd collect data static html page , create similar (replica) form inside iframe (with above attributes viz method & action mainly); if there lot of fields i'd struggle via javascript alone. there jquery solutions thing? you try using jsonp alternative method. quick overview of jsonp can found on wikipedia ( http://en.wikipedia.org/wiki/json#jsonp ). jquery implements jsonp support through .getjson method ( http://docs.jquery.com/ajax/jquery.getjson ). unfortunately, use jsonp need submit form data query string (get request, instead of post request). can serialize form query string using jquery's serialize method ( http://docs.jquery.com/ajax/serialize ).

we've got model-view-presenter setup our .net compact framework app. standard cf form implementing view interface, , passed constructor of presenter. presenter tells form show calling view.run(); view show() on itself, , presenter takes on again, loading data , populating view. problem view not finishing showing before control returned presenter. since presenter code blocks few seconds while loading data, effect form not visible few seconds. it's not until after presenter finishes it's data load form becomes visible, though form called show() on before presenter started data loading. in standard windows environment, use .shown event on form... compact framework doesn't have this, , can't find equivalent. does know of even, pinvoke, or other way form visible before kicking off code on presenter? @ point, i'd ok form calling presenter , telling presenter start it's data load. fyi - we're trying avoid multi-threading, cut down on complexity , re...

so heres code: item = [0,1,2,3,4,5,6,7,8,9] item in z: if item not in z: print item z contains list of integers. want compare item z , print out numbers not in z when compared item. can print elemtens in z when compared not items, when try , opposite using code above nothing prints. any help? your code not doing think think doing. line for item in z: iterate through z , each time making item equal 1 single element of z . original item list therefore overwritten before you've done it. i think want this: item = [0,1,2,3,4,5,6,7,8,9] element in item: if element not in z: print element but like: set(item) - set(z)

i have 3 uiimages in uiscrollview , initializing these images in following way: uiimage *dimage = [[uiimage alloc] initwithdata:data]; where data nsdata gotten url request. after caching images. when check memory allocation 3 images takes 472 kb each , allocation has been requested "img_data_lock" coregraphics library. when check size of image on disk cache 230kb each. i dont know how can take more space. hope question clear. not sure "disk cache" you're looking @ memory , disk usage weakly related. data used create uiimage part of data object uses. means active object can use more memory data created it. to further complicate things, uiimage purge of image data under low memory situations size of uiimage object can vary on course of existence.

imagine have 2 applications application , application b. insert records exist in application application b. sql server reporting server available on application a and wondering if possible build report gathers record need , publish web service can consume on application b , inserts. application , b in 2 different web servers separated internet. if possible post link shows example? btw: experience ssrs null, have been web developer quite while have general understanding of need 1 point me right direction. thanks in advance. ssrs not designed serve data other webservers, designed nicely layout , display data 1 or more sql servers. it seems can connect ssrs external sql servers when have the right licensing . if want application b display data both sql servers can use 1 ssrs report on computer b display data both. however seems want inserts on computer b, using report computer a. not use report that, direct connection using odbc, jdbc or inter-database connecti...

the mysql rand() function notoriously slow in select statements, true insert statements well? insert new row random number in following way: insert new_table (field1, field2, randomfield) values ('hello', 'ola', rand()); will rand() function become slow table gets larger , larger? will rand() function become slow table gets larger , larger? no. rand() getting slower on big tables when used in conjunction order by or where . in example, making one call rand() not performance problem.

is there latex command prints "last modified" date of actual document? since latex projects consist of more 1 file command ideally prints date of actual file, not of project. unfortunately, tex not provide commands such information; way such information by running non-tex script create tex file before running latex , including file in main latex document somehow, or by running external script from tex (which works if so-called write18 or shellescape feature enabled; you'd have consult manual of tex implementation this, , not have stubborn sysadmin). it possible extended texs support file info commands (luatex perhaps?), it's not part of tex proper.

i reading stackoverflow post regarding sorting vector of pairs second element of pair. obvious answer create predicate, 1 answer used boost caught eye. std::sort(a.begin(), a.end(), boost::bind(&std::pair<int, int>::second, _1) < boost::bind(&std::pair<int, int>::second, _2)); i've been trying figure out how boost::bind works, or @ least how use it, can't figure out purpose of placeholder arguments _1 , _2 are, , boost documentation doesn't sink in @ all. could explain specific usage of boost::bind? p.s. original question: how sort vector of pairs based on second element of pair? this expression: boost::bind(&std::pair<int, int>::second, _1) < boost::bind(&std::pair<int, int>::second, _2) namely, use of < operator defines functor between 2 other functors, both of defined bind . the functor expected sort needs have operator() looks this: bool operator()(const t& arg1, const t& arg2);...
