something along line of: int n = sscanf(%s %s ... it save how many string element on given line in int n, the file can contain many lines each line having many elements e.g. efefefef efefef dfefe fefef eef efef efef efefef efefef efefef efefe efeefef [wdfefefef] first line n = 2 ; second line n = 6 also how should remove brackets strings thr string inside bracket? regards presuming 'element' mean word, best bet use strtok , pass appropriate list of terminators (which include space, '[', ']', etc.

i've been printing images using standard window.print() function. i'm dealing image when printed, doesn't print correctly on 1 page(takes 2 pages no matter how small make image). put image in .pdf can format print size , orientation need, have no clue how make .pdf print without new popup window. there solutions out there, perhaps image size accomplish printing image onto 1 8 1/2 x 11 inch page? i've googled no luck, i'm kind of new, maybe i'm searching incorrectly.

the task calculate sum of natural numbers 0 m. wrote following code using swi-prolog: my_sum(from, to, _) :- > to, !. my_sum(from, to, s) :- = 0, next 1, s 1, my_sum(next, to, s). my_sum(from, to, s) :- > 0, next + 1, s s + next, my_sum(next, to, s). but when try calculate: my_sum(0,10,s), writeln(s). i got false instead of correct number. going wrong example? this surely false next \= 0: s s + next . more fundamental problem you're doing computation in 'reverse' order. is, when from > to , program stop, don't 'get back' result. should add accumulator (another parameter, propagated recursive calls) , unify partial sum @ last step... anyway, should simpler: my_sum(from, to, s) :- < to, next + 1, my_sum(next, to, t), s t + from. my_sum(n, n, n). | ?- my_sum(2, 4, n). n = 9

yesterday, had problem because couldn't manage open xml file (it owuld give me filenotfoundexception) located in ressources folder of .jar file, managed open on eclipse using following lines of code. can see old problem here . code problem : file xmlfile = new file("ressources/emitter.xml"); configurableemitter emitter = particleio.loademitter(xmlfile); someone told me 1 way use getclassloader().getressourceasstream method open xml file in .jar file exported inputstream i= this.getclass().getclassloader().getresourceasstream("ressources/emitter.xml"); configurableemitter emitter = particleio.loademitter(i); unfortunately, solution works when export project .jar file, if want go debugging program, have take old code works on eclipse. my question is: there better way without having change code if want export or if want debug it? thank you edit : thank all, works fine problem put ressources folder : +project +src +ressources +emitter.

i need somehow "return" variable custom subclass of chef::provider::package recipe called from, can use variable later in same recipe. i tried add custom chef::resource::package subclass attribute , appropriate setter/getter wrapper set_or_return function. can write , read attribute chef::provider::package subclass, when try access attribute recipe see nil value. can illustrated following recipe: a = apt_package "bzip2" action :install end # won't work, a.version nil log "bzip package version #{a.version}" however, can see in lib/chef/provider/package/apt.rb @current_resource.version being set: @current_resource.version(installed_version) what right way of reading arbitrary attribute ( version in example) of chef::resource::aptpackage instance, created apt_package provider same recipe? maybe like:: a = apt_package "bzip2" action :install end ruby_block "init logger"

i trying use mnist database in order recognize hand written digits. have far binary matrix represents digit , algorithm written in matlab . love on getting started using mnist database recognize digit binary image. thanks. if using matlab , have binary images need to: 1) extract features images (you have many choices). example, can start using raw pixels ==> convert each image matrix row vector. (use part of data training , rest testing) create feature matrix these row vectors. each row "instance" in feature matrix. 2) can select , try different classifiers. try example, svm (support vector machine). basic way using svmtrain , svmclassify functions. usage simple , explained in matlab's help. 3)test different partitions of data. 4)experiment other features , classifiers.

so i'm new python , i'll asking many noob questions throughout learning process (if haven't been asked/answered of course). one question have if there way save multiple dictionaries 1 text file using pickle, or if each individual dictionary has saved it's own separate file. example, if want create program manage web accounts, each account having variety of arbitrary keys/values, can save these individual accounts 1 archive separate dictionaries? thanks in advance, , noob appreciate example code and/or suggestions. one quick solution place both dictionaries in list, pickle list. here example writes out binary file. import cpickle pkl myfirstdict = { "hat": 7, "carpet": 5 } myseconddict = { "syrup":15, "yogurt": 18 } mydicts = [myfirstdict, myseconddict] pkl.dump( mydicts, open( "mydicts.p", "wb" ) ) here 1 loads it. import cpickle pkl mydicts = pkl.load( o

my app works stepping out of main activity, starts second activity, displays image chosen user , analyzes image. after analysis of first image, used button go main activity , proceed second activity again choose second image. user chooses second image, android give me out of memory error. tried keeping track of available memory. strange thing right before second image chosen, there more memory available before first image chosen. how should go solving this? thanks! ps code runs out of memory @ bitmapfactory.decodefile(picturepath); if running on pre 3.0 hardware, memory value see not include memory used bitmaps, that's possible reason behavior described. as rule of thumb, should check dimension of image app retrieve dynamically (either user selection or net), , scale size makes sense app. example, gallery app should rescale picture phone takes dimension of screen. below code sample decoding scaled bitmap: private bitmap decodefile(file f, int width_tmp,

validation works fine until make use of validationgroup. afterward form submits no validation occurs. href on linkbutton before , after use validationgroup. before: javascript:dopostbackwithoptions(...) after: javascript:__dopostback(...) the causesvalidation property set true. why adding validationgroup change postback code that? once set validationgroup on button, button should trigger matched group validator. asp.net generates webform_dopostbackwithoptions because there group validator on page matching button's attribute ‘validationgroup’. your link button markup code should similar that: <input type="submit" name="btngroup1" value="group1" onclick="javascript:webform_dopostbackwithoptions( new webform_postbackoptions('btngroup1', '', true,'group1','', false, false))" id="btngroup1" /> through debugging js code, should able find there js function used find grou

i borrowed this gentleman in order request signal strength of wireless connection on device. use ioctl operstate , whether or not there's up/down stream information flowing on connection. basically, i'm attempting modernize of device, adding real-time status icons of link operability, quality, , activity. originally, using popen() cat , parse /proc/net/wireless , /sys/class/net/wlan0/operstate. issue fail (i assume because os had locked file) causing crashes. so, questions two: one, can use ioctl in way similar 1 described in link above monitor operstate , connection activity? information find pertaining ifreq, not iwreq. two, occurred me while writing should have kernel telling application when status of wireless device changes, shouldn't i? can't imagine various desktops' system trays have polling loops in them. actual two: there way have kernel feed information application operstate, link quality, , link activity in real-time? thank in advance. =
