ok, need suck @ linq! this collection contains x number of time slot dto's given day. list<timeslotdto> timeslots = new list<timeslotdto>(); the timeslotdto contains datetime slotstart property , bool isreserved . collection works, contains number of timeslots want. fine. now problem. want use collection in linq query. have 2 tables," staff " , " timeslots "(well three, if might able add last table query myself) the " timeslots " table contains: staffid(fk) timeslotid(pk) slotstart activityid(fk third table). the " staff " table contains: staffid(pk) navigation property timeslots based on this...i want produce result each staff member has list of timeslots , slots in collection has same date in timeslots table isreserved prop should set true. so timeslots collection contains possible slots given day. timeslots table contains reservations. want x-check collections find reservations each staff mem

consider following: void foo(int start, int end) { int mid = (start + end) / 2; } void bar(int start, int end) { int mid = (start + end) * 0.5; } why foo compiles while bar not? dividing 2 implicitly casts result int while multiplying 0.5 gives un-casted double : cannot implicitly convert type 'double int. explicit conversion exists(are missing cast?) what c# language designers' reasoning behind this? the / integer division ( 5/3 = 1 ). make float division 1 of operand must floating point ( float or double ). because there cases when application wants access quotient or remainder of division (for remainder use % ). also, integer division faster floating one. on other hand, multiplying float gives float. save integer type have type cast yourself. floating point values have different representation in memory , can lead loss of precision. it same thing in programming languages: of them have integer division , floating point division,

for reason if/else statements isn't working correctly me in c++ the problem when variabel equal right (höger), won't output if statement, instead go on else statement. if replace letter 'ö' 'o' becomes 'hoger' instead, if statement work. whenever write word 'höger' won't go if statement, instead go else statement. if make variabel equal 'hoger', , write 'hoger', work. how can make possible writing 'höger' if statement recognizes instead? it's if swedish letters don't work. my code this: #include <iostream> #include <string> using namespace std; int main() { setlocale(lc_all,""); string test; // define variabel cout << " höger elle vänster"<<endl; // right or left cin >> test; if(test == "höger") { // if right, output this. cout <<"du valde höger"<<endl; } else if(test == &qu

i'm learning aspects of clr in c# , read topic in "clr via c# 4th edition". it said each instance of type has pointer vtable , in book didn't differentiate between static, non-static , virtual methods. according methods declared in method table withing type object. think "vtable" name misleading, , virtual methods table part of normal method table in each type object. true? that make sense because when calling virtual method, object referenced , clr checks objects type , calls method associated objects class. or wrong? another question: static , non static methods in method table. understanding differentiated parameter. non-static methods object related, when calling methods, this-pointer passed in reveal object called it. static methods not need parameter. right? i know quite theoretically hope there people can me! really nobody?

after completed testing, have moved images on spritesheet. i loaded batchnode appropriate files , images load fine. but running issue of swapping textures out. when images individual files, there no problem. seems cctexture2d doesn’t sprite sheet. i have objects stored in multidimensional array, can run through them , update image. here did when worked: cctexture2d* tex = [[cctexturecache sharedtexturecache] addimage:@"alt-image.png"]; [((myfunobject*)[[myfunobject2darr objectatindex:j]objectatindex:i])->img settexture: tex]; here doing now: cctexture2d* tex = [[cctexturecache sharedtexturecache] addimage:[ccsprite spritewithspriteframename:@"alt-image.png"]]; [((myfunobject*)[[myfunobject2darr objectatindex:j]objectatindex:i])->img settexture: tex]; myfunobject subclass of ccsprite , has ccsprite img property set. run through array , find objects , replace image new image “alt-image.png” . seems simple, outside of sprite sheet

i'm working on project compares text. here relevant piece of code: def post(self): = unicode(flask.request.form['a']) b = unicode(flask.request.form['b']) i posted large pieces of text project gutenberg , errors this: unicodeencodeerror: 'ascii' codec can't encode character u'\xe9' in position 6: ordinal not in range(128) based on this page have tried errors ignore , errors replace , error: typeerror: decoding unicode not supported if possible want able take in robust set of characters possible. hoping there python library allow this. here more of code. think problem may occur when try turn input string. c = a.split() d = b.split() both = [] x in c: if x in d: both.append(x) x in range(len(both)): both[x]=str(both[x]) final = [] x in set(both): final.append(x) missinga = [] x in c: if x not in final , x not in missinga: miss

i examining object dump of file , want figure out possible addresses. the approach using involves using perl , regex extract words the format of object file this 00000000000044444 <function> 44448: 48 ca add .... 4444c: 48 ca 55 call .... 44450: 48 ca 8d 55 jmp.. i trying extract 48 ca 48 ca 55 48 ca 8d 55 currently, thought regex /(\s[0-9a-f][0-9a-f]\s)/g however, extracts every other, i.e 48, 8d, 55 , parse 48 , cant parse ca because previous space character has been consumed (at least understanding) /(\s[0-9a-f][0-9a-f]\s)|([0-9a-f][0-9a-f]\s)/g parses things shouldnt add instruction dd any how can extract these pairs of numbers deliminated space? edit: updated more realistic format of file. thank you instead of \s , want word boundary \b . while (<data>) { @nums = m/\b([[:xdigit:]]{2})\b/g; print "@nums\n"; } __data__ 00000000000044444 <function> 44448: 48 ca 8d 55

i developing game in unity, need enemy attack , objects health decrease. attack sequence is: - 1) play attack animation 2) decrease health 3) repeat until dead edited: sorry should have shown code, here is: // check if ai in attack range if (transform.position == targetpostion) { // if target has more 0 health if (targethealthscript.health > 0) { // play animation , decrement health animation.play("bite"); targethealthscript.decrementhealth(10.0f); } } the script written in c# currently have working extent however, health decrement function keeps getting called repeatedly, need way slow down. have tried use coroutines yield statement without success. if has suggestions grateful thanks try using update function if know how long animation take , use time.deltatime enter link description here figure out how time has passed. then decrease health based on them.
