possible duplicate: is sql clause short-circuit evaluated? i have following question regarding query: select * sometable 1=1 or (select count(*) table2 > 0) if first condition true ( 1=1 ), sql server still inner select? or stop when first condition true (like c) it stops when (1=1) true. can check using ctrl-m ctrl-e consider query select * master..spt_values 1=1 or (select count(*) master..sysobjects) > 0 the execution plan shows scan in master..spt_values , no activity in sysobjects . contrary c, not stop when leftmost condition true, instead query optimizer works out independently of order presented least cost evaluate. in case of constants 1 vs 1 winner clear.

i have string came old database of unknown character encoding. having trouble encoding/filtering string show correct text. what data looks in database: marronnière à quatre pans what need string show as: marronnière à quatre pans specifically, having trouble parsing string can display character à ( &#224; ) this asp.net 2.0 site written in vb using sql server 2005 database. not sure if matters, data comes column collation: sql_latin1_general_cp1_ci_as i've tried encoding string various encodings in code no avail. i've passed string (encoded different ways) byte array find unique byte pattern bad characters without success. any ideas or leads appreciated, thanks. it sounds collation in sql server database doesn't match character encoding used :( it's common mistake careless developers. that's why sql server administration tools showing weird characters rather strings expecting. possibly utf-8? in utf-8 à represented bytes 0xc3 0x...

i have page don't want outbound links send referrer destination site doesn't know came from. i'm guessing isn't possible want make sure there weren't hidden javascript magic , work (if not most) browsers. maybe clever http status code redirecting kung-fu? something perfect <a href="example.com" send_referrer="false">link</a> i looking same thing, , seems this feature of html5 . the tag looking rel="noreferrer" . it implemented in webkit (chrome, etc.) , as firefox , mileage may vary.

i using apache ant scripts building web application. have written targets in build.xml file , script running fine. remember using "build" command run ant build instead of "ant build". can tell me how achieved? bit curious on this. there's no built in "build" command. create simple script file called "build" in same directory launched ant build. create text file contents: ant build in windows save file called build.bat can type build command line start build. on unix or linux, save file build , make executable (with chmod +x build ). you'll need type ./build run. i don't think there's lot of value doing replace simple case of ant build , if have regularly run build has multiple targets, or need pass in system variables come in useful.

i'd run script every time close bash session. i use xfce , terminal 0.4.5 (xfce terminal emulator), run script every time close tab in terminal including last 1 (when close terminal). something .bashrc running @ end of every session. .bash_logout doesn't work you use trap (see man bash ): trap /u1/myuser/on_exit_script.sh exit the command can added .profile/.login this works whether exit shell (e.g. via exit command) or kill terminal window/tab, since shell gets exit signal either way - tested exiting putty window.

i've read tail-call optimization in scheme. i'm not sure whether understand concept of tail calls. if have code this: (define (fac n) (if (= n 0) 1 (* n (fac (- n 1))))) can optimized, won't take stack memory? or can tail-call optimization applied function this: (define (factorial n) (let fact ([i n] [acc 1]) (if (zero? i) acc (fact (- 1) (* acc i))))) a useful way think tail calls ask "what must happen result of recursive procedure call?" the first function cannot tail-optimised, because result of internal call fac must used, , multiplied n produce result of overall call fac . in second case, however, result of 'outer' call fact is... result of inner call fact . nothing else has done it, , latter value can passed directly value of function. means no other function context has retained, can discarded. the r5rs standard defines 'tail call' using notion of tail context , i...

i have finished developing executable desktop application generate fractal image based on passed-in arguments. output type jpeg. now developing site under asp.net mvc 3. want use executable within site. is possible use without converting class library , recompiling? if mean "to run on user's machine", not "as is" - might want @ silverlight that. if mean "to use @ server", of course depend on how operates (whether prompts input etc), , how works (does use gdi+, example? isn't recommended use on web servers). but sure; can shell exe process.start , or if .net exe can either add reference directly exe , use as library (if has appropriate code) there way run in-process via appdomain.executeassembly - not sure latter idea on web-server, though... if exe talks stdout . for getting image client, want processing happen (perhaps caching) in route uses return file(...); mvc simulate image stream.

in experience, ocr libraries tend merely output text found within image not where text found. there ocr library outputs both words found within image as as coordinates ( x, y, width, height ) words found? most commercial ocr engines return word , character coordinate positions have work sdk's extract information. tesseract ocr return position information has been not easy to. version 3.01 make easier dll interface still being worked on. unfortunately free ocr programs use tesseract ocr in basic , report raw ascii results. www.transym.com - transym tocr - outputs coordinates. www.rerecognition.com - kasmos engine returns coordinates. also caere omnipage, mitek, abbyy, charactell return character positions.

i have been following railscasts 'nested model form parts 1 & 2' survey form containing questions in turn contain answers. thing when survey form displayed, question field, along 1 answer field displayed. when user clicks on 'add question' field, question field displayed. no answer field displayed until user clicks on 'add answer'. i both question field , answer field displayed when user clicks on 'add question'. currently code this: # helpers/application_helper.rb module applicationhelper def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")...

i have string "region_2>0" want replace _2 string.empty using regex. my expression ((_)[^_]*)\w(?=[\s=!><]) in both regulator , expresso gives me _2. however, code(c#): regex.match(legacyexpression, "((_)[^_]*)\\w(?=[\\s=!><])").value gives me "_2>0", causes replace wrong (it returns "region" since removing whole "_2>0" instead of "_2". result want "region>0". shouldn't code , regex programs give same results? , how can work? (note string not static, in many different forms, rule want replace last _x in string string.empty. thanks! i copied code new project: static void main(string[] args) { var legacyexpression = "region_2>0"; var rex = regex.match(legacyexpression, "((_)[^_]*)\\w(?=[\\s=!><])").value; console.writeline(rex); console.readkey(); } the output _2 .

i want app create mini dump debug unhanded exceptions. i may not know type of mini dump want until after dump has been created, combinations of minidump_type flags should use give me complete dump possible? i came following list of debuginfo.com link (thanks david) , msdn page. not flags covered in debuginfo.com link. using these flags should create comprehensive, big mini dump. include: minidumpwithfullmemory - contents of every readable page in process address space included in dump. minidumpwithhandledata - includes info handles in process handle table. minidumpwiththreadinfo - includes thread times, start address , affinity. minidumpwithprocessthreaddata - includes contents of process , thread environment blocks. minidumpwithfullmemoryinfo - includes info on virtual memory layout. minidumpwithunloadedmodules - includes info unloa...

i have set of enumeration values (fault codes precise). code 16 bit unsigned integer. looking data structure represent such enumeration. similar question has been asked here: what's best c# pattern implementing hierarchy enum? . hierarchy deeper. sample enumeration values current = 0x2000, current_deviceinputside = 0x2100, shorttoearth = 0x2120, shorttoearthinphase1 = 0x2121, shorttoearthinphase2 = 0x2122, shorttoearthinphase3 = 0x2123 use case when user provides code ui has display equivalent meaning of code hierarchy. example, if user provides value 0x2121 ui has display short earth in phase 1 in current @ device input side . best way represent using hierarchical notation: current : deviceinputside : shorttoearth : shorttoearthinphase1 . competing approaches have 3 competing approaches represent enumeration: create enumeration @ each level of hierarchy. use controller class resolve name. store enumeration values in xml , use linq generate meaning of code. st...

i know if there's way use rails validations on custom action. for example this: validates_presence_of :description, :on => :publish, :message => "can't blank" i basic validations create , save, there great many things don't want require front. ie, should able save barebones record without validating fields, have custom "publish" action , state in controller , model when used should validate make sure record 100% the above example didn't work, ideas? update: my state machine looks this: include activerecord::transitions state_machine state :draft state :active state :offline event :publish transitions :to => :active, :from => :draft, :on_transition => :do_submit_to_user, :guard => :validates_a_lot? end end i found can add guards, still i'd able use rails validations instead of doing on custom method. that looks more business logic rather model validation me. in pro...

i'd override datapointstyle of lineseries in wpf toolkit chart : <chart:lineseries> <chart:datapointseries.datapointstyle> <style basedon="{staticresource {x:type chart:linedatapoint}}" targettype="{x:type chart:linedatapoint}"> <setter property="width" value="20" /> <setter property="height" value="20" /> </style> </chart:datapointseries.datapointstyle> </chart:lineseries> however when lose automatic palette coloring each series has different color. applying datapointstyle causes them turn orange. until suggests better method, i've manually set colors. guess won't using automatic palette now. <style x:key="simpledatapointstyle" basedon="{staticresource {x:type charting:linedatapoint}}" targettype="{x:type charting:linedatapoint}"...

i have several ordered list of x/y pairs , want calculate ordered list of x/y pairs representing average of these lists. all these lists (including "average list") drawn onto chart (see example picture below). i have several problems: the different lists don't have same amount of values the x , y values can increase , decrease , increase (and on) (see example picture below) i need implement in c#, altought guess that's not important algorithm itself. sorry, can't explain problem in more formal or mathematical way. edit: replaced term "function" "list of x/y pairs" less confusing. i use method justin proposes, 1 adjustment. suggests using mappingtable fractional indices, though suggest integer indices. might sound little mathematical, it's no shame have read following twice(i'd have too). suppose point @ index in list of pairs has searched closest points in list b, , closest point @ index j. find closest poi...
