c# - How to get this code to work using the speech recognition engine instead of the default windows popup recognizer -


i still working on speech pronunciation test. have code, need use speechrecognitionengine instead of system popup recognizer. bit of working code in vb, though prefer work in c#, has been difficult settle whatever code or programming language can get. code totally functional, , can tested pasting empty vb projects, , including import system.speech.recognition. can show me how make code use speechengine .

i can discuss setting default audio input , getting rid of recognizer start code, of course must removed. but, keep things simple, have left code live testing. thanks

imports system.speech.recognition  imports system.threading  imports system.globalization  public class form1      ' recogniser & grammar     dim recog new speechrecognizer     dim gram grammar     ' events     public event speechrecognized _         eventhandler(of speechrecognizedeventargs)     public event speechrecognitionrejected _         eventhandler(of speechrecognitionrejectedeventargs)     ' word list     dim wordlist string() = new string() {"yes", "no", "maybe"}     ' word recognised event     public sub recevent(byval sender system.object,             byval e recognitioneventargs)         labelyes.forecolor = color.lightgray         labelno.forecolor = color.lightgray         labelmaybe.forecolor = color.lightgray         if (e.result.text = "yes")             labelyes.forecolor = color.green         elseif (e.result.text = "no")             labelno.forecolor = color.green         elseif (e.result.text = "maybe")             labelmaybe.forecolor = color.green         end if     end sub     ' recognition failed event     public sub recfailevent(byval sender system.object,             byval e recognitioneventargs)         labelyes.forecolor = color.lightgray         labelno.forecolor = color.lightgray         labelmaybe.forecolor = color.lightgray     end sub     ' form initialisation     private sub form1_load(byval sender system.object,             byval e system.eventargs) handles mybase.load         ' need these british english rather default         thread.currentthread.currentculture = new cultureinfo("en-gb")         thread.currentthread.currentuiculture = new cultureinfo("en-gb")         ' convert word list grammar         dim words new choices(wordlist)         gram = new grammar(new grammarbuilder(words))         recog.loadgrammar(gram)         ' add handlers recognition events         addhandler recog.speechrecognized, addressof me.recevent         addhandler recog.speechrecognitionrejected, addressof me.recfailevent         ' enable recogniser         recog.enabled = true     end sub end class

java - pagination of xlsx file to XSSFworkbook using apache POI -

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
