this question has answer here: can bind array in() condition? 19 answers i have array called $restaurantarray contains selection of restaurant id's. is there anyway can execute mysql query return rows if id equal 1 of these restaurant id's in array? thanks. you can use in mysql query. implode array $restaurantarray string, using comma delimiter; cover string brackets; , use result string input query. like // uncomment if data needs sanitized // $restaurantarray = array_map("mysql_real_escape_string", $restaurantarray); $input = '(' . implode(',', $restaurantarray) . ')'; $query = "select foo id in $input";

i have add graphics.h , winbgim.h libraries, , libbgi.a mingw. can found here . archive has folders indicate directory should placed under /mingw . have added -lbgi -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32 link options, specified in following link: http://www.infobits.ro/medii-mingw-developer-studio3.php .

i started using boost's python library wrap parts of rather large c++ library. quite chance, discovered every python object created boost python, @ least bigger size of python list. simple types using noddy_noddytype example c-python api docs , can quite expose new object type instance, noddy_noddyobject . using raw c-python api, small , simple custom python object can be:- >>> import noddy, sys >>> print sys.getsizeof( noddy.noddy ) # pytypeobject size? 872 >>> print sys.getsizeof( noddy.noddy() ) # pyobject size 16 and compare base object:- >>> print sys.getsizeof( object ) 872 >>> print sys.getsizeof( object() ) 16 that's expected, when expose noddy_noddyobject using boost python? >>> print sys.getsizeof( noddy.noddy ) 904 >>> print sys.getsizeof( noddy.noddy() ) 80 say what?!! that's not ideal... object instances 5 times bigger need be! (this differ on non-64-bit machin...

i want check number of command arguments in q script , return error message if .z.x doesn't match intended number of arguments. far came line: if[count .z.x < 4; '`badusage] "arguments ok" i never past if statement, returns `badusage, regardless of number of arguments i'm using. how check correct number of arguments, print error message , exit script? its because statements evaluated right left. .z.x < 4 evaluated first, , count of result. q)count .z.x < 4 0 q)4 > count .z.x 1b

i new wpf , working on projects our ui. quote problem 1.) have openfiledialog box in user can select dll or text files. 2.) if select dll fine , user operates in normal way, if user selects text files have processing on text files. 3.) there few steps on text file around 4-5 steps. after steps convert specfic file , user proceeds in normal way. what have done when user selects text files openfiledialog processing , show in expander status image, labels (this label contains command executed),etc. but problem expander shows after every process completes, not show real time how ti changes. started coding in wpf learning stuff , dont show how bring step step , how update ui when corresponding valeus changes in processing. snippet of code: browser_button() { if ( button == ok ) see if text or dll if dll continue if text files processing 4-5 steps expander contains processing logic give result of each stage. } expander_expander(object,event) { ...
