i have evp encrypted file want send on socket. however, realised nothing being sent because seems nothing stored in array read file into, sure there stored since able decrypt after reading file. the code snippet below part boggling me. file *fp; long lsize; fp = fopen ( evp_file , "rb" ); fseek(fp, 0l, seek_end); int fsize = ftell(fp); fseek(fp, 0l, seek_set); unsigned char *indata = malloc(fsize); fread(indata,sizeof(char),fsize, fp); printf("%s\n", indata); // printing indata returns me nothing @ //then decryption //decrypting indata works! , want. as commented, no output when print indata. there doing wrong here? need store in array can send on socket. ps. when use plain text file, works fine. thanks in advance!! if it's text data ( ascii characters, perhaps utf-8, not binary ) need nul terminate buffer, add 1 byte malloc() ed size , then indata[fsize] = '\0'; ...

i'm working installshield , creating installation addon. must read registry program x has been installed , add necessary files found location. problem : on 32bit computer registry found under hkeylm\software\x. on 64bit computer registry found under hkeylm\software\wow6432node\x. so how can read registry correct registry value , set found value installdir? firstly find if target machine 64 or 32 bit machine.you can use sysinfo.biswow64 similar commands. once found run reg commands thru if loop , achieve goal.

i have chart plots flow vs power. want adjust rotation of data label sits on top of line on chart match slope of line. first point plotted @ 25000, 87000; second point plotted @ 53000, 182000. if manually count gridlines , tangent(theta) = opposite / adj answer makes sense ~22º if use actual data graph angle wrong. eyeballing graph, looks 22º using plot data gives me 73º. it seems confusing opposite , adj. 73º right answer these data. you have 2 points p1 = (x1, y1) , p2 = (x2, y2) . segment p1p2 has slope angle (in radians) a = atan2(y2 - y1, x2 - x1) (i don't know exactly, whether atan2 or arctan2 function exists in vba math library - a discussion found)

i have plane (screen) width , height (monitor resolution, not square). , i'd distribute points on plane (approximately) same distance each other. for example: 1 point in middle, 2 points in middle of y axis, , x axis divided 3 3 points may triangle, if sceen wide enough, thay can alighned in same y 4 second part of above, or rectangle.. etc 8 points max is there algorithm this? thank time! edit: same distance each other , plane border edit2: compute centers of mass groups of objects on behavior simulate on plane. depending on precision want: you can stochasticaly correct answer poisson disk sampling. specifically, poisson disk sampling random sampling such no points closer specified radius. such thing can efficiently (linear time) implemented in high dimension - e.g. : c++ code robert bridson : http://www.cs.ubc.ca/~rbridson/download/curlnoise.tar.gz implementing paper http://www.cs.ubc.ca/~rbridson/docs/bridson-siggraph07-poissondisk.pdf you ...

i have single web page responsible delivery on 500 images browser. sizes vary between 50kb , 80kb. the server being used nginx , there varnish proxy being used. now, how can make process efficient can possibly be? i have 2 thoughts , imput experienced people here. my thoughts are: set multiple subdomains , serve batches these. believe best number of subdomains use 12. use ajax load batches browser when needed user scrolls down. i think option 2 here doesn't solve problem; gets around it. focus on making process efficient , fastest can possibly be. you're loading 1 page 500*50kb ~ 25mb of data, that's insane pagesize! no matter that's gonna feel slow compared average pagesisze of around 1 mb currently . loading of dynamically via ajax when needed makes way more sense. alternatively split multiple plages. if you're set on 1 giant non-dynamic page then: make sure have cache headers set allow caching (won't hep first load) the m...

i need send emails formatted html. seems html email counts "view" element makes sense render using jsp. however, emailer task written in pure java. how can jsp output java? i.e. envision: emailbody.jsp: <c:out var="invoicebody"> <lots of html> ${invoice.price} etc... </c:out> emailsend.java: setup db connection setup email call emailbody.jsp email.body = invoicebody email.send etc... something that... right scraping through http server seems wrong. what best way format html emails? using tomcat 7, servlet 3.0... thanks you can use scripting language mvel populate html file want send out email. check mvel 2.0 templating guide i hope puts in right direction. there other alternatives szymon biliński pointed out.listing them below freemarker velocity

i'm new cucumber, , i'd ask how dry out code (which not contain errors): when /^the user page$/ users_path when /^the review page$/ reviews_path i tried use regexp like when /^the (.+) page$/ $1.to_s+'s_path' but apparently wrong. in advance! solution (based on answer aledalgrande ): when /^the (.+) page$/ send("#{$1}s_path") this should work: when /^the "(.+)" page$/ |destination| send("#{destination}s_path") end

i want sum integers between , including min , max recursive method. example: min = 1, max= 5, sum = 1 + 2 + 3 + 4 + 5 my issue can't find how stop "loop" created recursivity: def sum_recursive(min, max) return min if #i don't know how stop min += (min + 1) sum_recursive(min, max) end i have used counter, need create variable reset original value each time function calls itself. is there way ? or different way organize method ? this should give correct answer: def sum_recursive(min, max) return min if min == max min + sum_recursive(min + 1, max) end the process simple enough: sum_recursive(1, 3) → 1 + sum_recursive(2, 3) → 1 + (2 + sum_recursive(3, 3)) → 1 + (2 + (3))

i working on (top-down) game requires code bounce projectile off of circular surface. the way work when projectile hits surface a hypothetical line drawn center of circle which used normal calculate angle of reflection of new trajectory. physics (such gravity) unnecessary. there more or less simple way of doing that? reflect line segment off circle. this reflexed line segment off circle. length of reflected line segment , incoming line segment circle intercept equal length of original line segment. if want reflected ray stop calculations when reflected vector has been worked out. assumes incoming line segment starts outside circle. if line starts inside line fails. can check if line starts inside circle getting distance circle center line start if less circle radius line starts inside circle. this in pseudo code don't php. sqrt() function sqrt of number. the incoming ray line segment. line.x1, line.y1 start , x2,y2 end line x1,y1,x2,y2 the circle x,y ...

i have need validate text entered textbox using javascript before it's sent off third party acted upon. to this, i'm using browserevent.keycode parameter keycode sent browser on key-up event, validating code whether it's allowed in textbox or not. this works fine across devices i've tested, apart chrome on htc 1 x. i've found annoying differences between various android , ios devices, return can work with. htc 1 x, however, returns 0 every key press apart backspace , enter keys, return 8 , 13 respectively. i've tried event.keycode , event.charcode , event.which browserevent.keycode , browserevent.charcode and browserevent.which codes, , returned 0 . basically, i'm stuck. have idea why keycode returned 0 on device, , how can detect keycode ? although doesn't answer immediate question, used of ideas lukas knuth gave me solve it. the process keycode of 0 caught , handed function runs contents of input box through ...

i'm using stripe cc processing , used stripe example form , js code. form has 2 separate fields expiration month , year. each has data-stripe="exp-month" , data-stripe="exp-year" i'd use 1 textfield month , year , have user enter input like: 10/2020 question since stripe reads data based on data-stripe attribute. there way can parse input 10/2020 1 textfield , programmatically set data-stripe attributes? i'm not sure how glued , being sent, have hidden input fields data-stripe="exp-month/year" attributes , split visible input value on / , set hidden values. here rather basic jsbin can see month , year in console output.

i'm new javascript , i'm having strange issue. javascript generated table elements not working in ie, worked fine in every other browser i've tried. managed isolate issue adding child elements in js: var table = document.createelement("table"); var tabler = document.createelement("tr"); var tab = document.createelement("td"); var node = document.createtextnode('test'); textdiv.appendchild(table); table.appendchild(tabler); tabler.appendchild(tab); tab.appendchild(node); the above creates table single text element in chrome, in ie blank. i did experimenting , found code: var table = document.createelement("table"); var tabler = document.createelement("tr"); var tab = document.createelement("td"); var node = document.createtextnode('test'); textdiv.appendchild(table.appendchild(tabler.appendchild(tab.appendchild(node)))); does work in both ie , chrome, table being formatted align center,...
