Labview Program changes behavior after looking at (not changing) the Block Diagram -


my labview program works charm, until @ block diagram. no changes made. not save. ctrl+e , ctrl+r.

now not work properly. restart of labview fixes problem.

my program controls 2 scanner arrays laser cutting simultaneously. force parallel working, use error handler , loops wait signal scanner. loops run more should.

what majorly happen in labview when open block diagram messes code?

edit: hard tell happening without violating non-disclosure agreement.

i'm controlling 2 independent mirror-arrays laser cutting. while 1 running 1 cutting-job, other supposed run other jobs. fast. when first finished meet @ same position , run same geometry @ same slow speed. jobs provided *.xml , stored .net objects. device runs recent job , overwrites when getting new one.

i can check if job still running. while true run while loop other jobs. loop runs few times , ignores wait-blocks degree. skips part reads xml job file, changes speed part fast again , saves it. runs 1 time fast.

@joe: no not. runs once well. afterwards not.

the way supposed move

the wrong way

there 1 thing can think of changes solely opening block diagram.

when block diagram opens, commented-out or unreachable-code-compiler-eliminated sections of code load subvis. if 1 of commented out sections of code somehow interfere running code, might have issue.

there 2 ways know of interfere... both of them improbable. a) have sort of "check vis in memory" or "check types in memory" you're using plug-in system. when commented-out sections load, change vis in memory. such systems not uncommon when parsing xml, maybe. b) using run vi method dynamically invoked vi execute top-level vi, loading diagram, discovers subvi of current program. vi cannot simultaneously top-level , subvi, call run vi returns error.

that's it. can't think of else. both ideas seem unlikely, given claim , lack of block diagram, figured i'd post hypothesis.

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). ...
