i'm not experienced in jsp. have application, uses spring framework, search. show these results in jsp page. when search returns 1 item, want jump page shows information item. is possible in jsp/spring? i've seen tags like: <c:redirect url="/somepage.html"/> that's jsp file. want (this naive bit of code)... <c:when test="${cmd.totalresults = 1}"> <c:redirect url="/loaditeminfo.html?id=someid"/> </c:when> thanks in advance advice , help! can omit regarding parameters involved; can figure out. i'm asking making happen. page loads. page sees there 1 result. page goes page result, happens anyway when user clicks search result. saves click. you should check number of items logic in spring controller not in jsp file. inside spring controller may have this: if(items.size==1){ //query items[0] info return new modelandview("iteminfo",model); } else{ return new model...

hi trying find rows in database (sql server) have character é in text executing following queries. select count(*) t_question patindex(n'%[\xe9]%',question) > 0; select count(*) t_question patindex(n'%[\u00e9]%',question) > 0; but found 2 problems: (a) both of them returning different number of rows , (b) returning rows not have specified character. is way constructing regular expression , comparing unicode correct? edit: the question column stored using datatype nvarchar . following query gives correct result though. select count(*) t_question question n'%é%'; why not use select count(*) t_question question n'%é%' ? nb: like and patindex not accept regular expressions. in sql server pattern syntax [\xe9] means match single character within specified set . i.e. match \ , x , e or 9 . of following strings match pattern.

while writing aysnc controllers in asp.net mvc2, ran against situation had call asyncmanager.sync . got me wondering: when retrieve httpcontext.current , what's going on? how asp.net know httpcontext i'm after? how current context associated thread, , how retrieved? thread scoped storage used, called thread local storage . this mechanism allows data affinitized thread i.e. thread allocates data sees data. useful creating called ambient programming models such httpcontext.current , transactionscope. mechanism allows data accessible @ time on executing thread without having "tramp" data through method parameters instance. it's elegant solution context\orthogonal problems. there number of ways of using tls including threadstaticattribute , thread.setdata\getdata.

possible duplicate: importance of varchar length in mysql table when using varchar (assuming correct data type short string) size matter? if set 20 characters, take less space or faster 255 characters? in general, varchar field, amount of data stored in each field determines footprint on disk rather maximum size (unlike char field has same footprint). there upper limit on total data stored within fields of index of 900 bytes ( 900 byte index size limit in character length ). the larger make field, more people try use purposes other intended - , greater screen real-estate required show value - practice try pick right size, rather assuming if make large possible save having revisit design.

whats best way generate java python? i want write decorator generates java code call json version of function (i can use existing decorators export json api). whats best way generate java, should consider stuff fsms here? ideally can write code once, server , generate code interface various languages (java first). edit (pulled comment on deleted answer): java code running on android, while python code in django server... also, want able statically generate java code, , have part of api people can use. you can create java code same way webapps create html: template. can have java source code compiled bytecode using regular java compiler ( see: package javax.tools ) not best option, option ( , quite simple btw )

we working on big application, comprising around 100 projects (40 views, 40 controllers/models, 20 utilities libraries). have outsourced bulk of work , deliverables come in randomly. when deliverable (a project), need run fxcop, stylecop, associated unit-tests, etc, etc. before committing source control. make easier, have mandated every project has solution file. allows run automated script on solution file tests before checking in. my question "can think of drawbacks having 1 solution each project?". drawbacks have discussed include: additional maintenance required developers. doesn't bother have outsourced development on fixed-price contract. sourcesafe bindings in solution file. have been huge issue, luckily migrated tfs year ago. we're in similar boat 200 projects, many of them common use, accross our various solutions of varying sizes. while disadvantage load time, 1 advantage debugging - i.e. if code calling other assemblies, it's...

suppose want have method passes begininvoke method of object parameter. how that? call looks this: myrandommethod(somecontrol.begininvoke); what method definition myrandommethod be? part of problem begininvoke has overloads, compiler gets confused 1 try pass parameter. maybe need find way version of begininvoke referring to? (though imagine decided parameter type) myrandommethod have have parameter delegate matches 1 of overloads somecontrol.begininvoke . example: public void myrandommethod(func<delegate, iasyncresult> foo) or public void myrandommethod(func<delegate, object[], iasyncresult> foo) (but please don't overload myrandommethod both of these signatures, otherwise you're asking confusion.)

i need create image filled (r,g,b) color. , color name (r,g,b) = black or red , on. can such thing opencv, , how it? opencv doesn't create images color, easiest way either fill or draw filled rectangle chosen color. see http://opencv.willowgarage.com/documentation/drawing_functions.html specifically http://opencv.willowgarage.com/documentation/drawing_functions.html#rectangle there isn't (afaik) function return color name, easiest way list of colors somewhere , check rgb values against pixel. if need closest rather exact match (rememebr there aren't names 244bit colors!) @ hsv color space

i working on trunk , changed did thought others might need them created patch before committing. now fellow dev working on branch (which comes trunk couple of weeks back) needs changes go on new server. i'm trying apply patch tortoise svn does'nt seam disparities of working copies. have : my trunk @ : d:\svn\trunk the branch @ : d:\svn\branches\thebranchineedtopatch am trying impossible ? there i'm missing ? can apply trunk patch branch working copy ? thanks help! perquisite: let's working on branch. check use svn info . url should pointing branch then can merge changes trunk branch using merge command svn merge -r from_revision:required_revision url/to/trunk . or svn merge -r 26:32 url/to/trunk . this bring change sets rev 26 32 of trunk branch. ah, there discussion on how tortoisesvn: using tortoisesvn how merge changes trunk branch , vice versa?

i need parse csv file using awk. line in csv this: "hello, world?",1 thousand,"oneword",,,"last one" some important observations: -field inside quoted string can contain commas , multiple words -unquoted field can multiple worlds -field can empty having 2 commas in row any clues on writing regex expression split line properly? thanks! as many have observed, csv harder format first appears. there many edge cases , ambiguities. example ambiguity, in example, ',,,' field comma or 2 blank fields? perl, python, java, etc better equipped deal csv because have tested libraries same. regex more fragile. with awk, have had success this awk function. works under awk, gawk , nawk. #!/usr/bin/awk -f #************************************************************************** # # file in public domain. # # more information email lorancestinson+csv@gmail.com. # or see http://lorance.freeshell.org/csv/ # # parse csv string array. # numb...
