if using sqldatasource bound data grid, how extend check box control read value query passing , checking or unchecking box because of that? i have tried this: public class checkboxyn : system.web.ui.webcontrols.checkbox { public string yesno { { if (this.checked) return "1"; else return "0"; } set { if (value == "1") this.checked = true; else this.checked = false; } } } but can't find control in asp.net, errors in html. you don't need override checkbox class, bind checked property datasource's bit column: <asp:checkbox checked='<%# eval("bitcolumnname") %>' />

thanks last night able program computing input properly, have trouble formatting output properly. problem: my program should print "is prime" on lines prime numbers. prints on ever line this: http://oi42.tinypic.com/30igbvq.jpg i cannot life of me figure out why doing this, of functions should work. stack need again! #include <iostream> using namespace std; void primecheck(int x); // proto void countr(int rnm, int lnm); // proto void prime(int x) // function finds prime factors of number. { int lastr = 2; int count = 0; while (lastr < x) { if (x % lastr == 0) { cout << x << " " << lastr << "*"; x /= lastr; } else ++lastr; } primecheck(x); // calls check if number prime, "is prime" } void console(int rnum, int lnum) // prompts user 2 numbers stores answers { cout << "please enter 2 numbers "; cin >> rnum; cin >> lnum; countr...

how hashmap internally implemented? read somewhere uses linked list while @ places mentioned arrays. i tried studying code hashset , found entry array , linkedlist used it looks this: main array ↓ [entry] → entry → entry ← here linked-list [entry] [entry] → entry [entry] [null ] [null ] so have main array each index corresponds hash value ( mod 'ed* size of array). then each of them point next entry same hash value (again mod 'ed*). linked-list comes in. *: technical note, it's first hashed different function before being mod 'ed, but, basic implementation, modding work.

i have python script gathers 10,000's of 'people' api , goes on request 2 other apis gather further data them , save information local database, takes around 0.9 seconds per person. so @ moment take long time complete. multi-threading speed up? tried multi-threading test locally , slower, test simple function without api interaction or web/disk related. thanks how many cores have? how parallelizable process? is problem cpu bound? if have several cores , it's parallelizable across them, you're speed boost. overhead multithreading isn't 100% unless implemented awfully, that's plus. on other hand, if slow part cpu bound might lot more fruitful c extension or cython. both of @ times can give 100× speedup (sometimes more, less, depending on how numeric code is) less effort 2× speed-up naïve usage of multiprocessing . 100× speedup translated code. but, seriously, profile. chances there low hanging fruit easier access of this. try line pr...

i'm working rails 4.0 , mongodb (mongoid) , have following code create documents: lines.each |l| insert.create(:position => 0, :content => l, :schema_id => moped::bson::objectid.from_string("52419d2f80a9b88bb9000002")) end this works fine , following output in mongo-database: { "_id": { "$oid": "5241ff1280a9b8f16e000057" }, "position": "0", "content": "blabla", "schema_id": "52419d2f80a9b88bb9000002" } the problem is, want have "$oid": before actual schema_id this: ... "schema_id": { "$oid": "52419d2f80a9b88bb9000002" } and got confuse of how can insert "$oid" followed colon manually.... would great if me... thx in advance!! you should not have $oid @ all, neither in schema_id or in _id , make indexing operations hard, or not possible mongodb. have $oid because parsing d...

i looking way override getresponsestream method of httpwebresponse class, in order have custom stream returned. goal modify stream. not sure if possible? being done in context of integrating web service , need strip away of content response stream. thoughts? you can't override httpwebresponse 's behavior. either wrap web-service api on client side, @jon suggested in comment, or, if want adventurous, change request , pointing proxy server modify stream required. it's not going trivial, though.

i have such situation: 1) 1 form named 'frm_iexplorer' webbrowser , loaded document it. 2) 1 class named 'printhtmldocument' creates webbrowser dynamically. load same document second, dynamically created webbrowser first webrowser. my approach in class like: dim ie new internetexplorer ie.navigate(frm_iexplorer.webbrowser1.document()) ... don't work. frm_iexplorer not accessible. how this?

def f(): return true print(f()) or def f(): return true if f(): print('true') else: print('false') should round in if statement or print out value, in python 3.3.2? print automatically converts input string representation. so, 2 methods exact same thing. considering that, why not use first? lot cleaner. also, second method can simplified: print('true' if f() else 'false') having code simple isn't necessary.

i using vlookup statement: =vlookup(b1232,sheet1!a:b,2,0) . cell in b1232 contains string: 'you rawk!!~' with "'" inside string want go , find, program retursn #n/a. believe vlookup command omitting opening single-quote when runs search, true? there way work around can run vlookup? i don't think quote problem - excel uses "~" [tilde] "escape character" has problem values contain "~". can use substitute function within vlookup replace "~" "~~" - when using 2 tildes first 1 tells excel treat second literal "~", i.e. use =vlookup(substitute(b1232,"~","~~"),sheet1!a:b,2,0) that work whether b1232 contains "~" or not

i'm curious, know why can't use setvalue write in different cell in custom function? the readme explains can't this, doesn't give reason on why: link custom functions return values, cannot set values outside cells in. in circumstances, custom function in cell a1 cannot modify cell a5. however, if custom function returns double array, results overflow cell containing function , fill cells below , right of cell containing custom function. can test custom function containing return [[1,2],[3,4]];. anyone knows if there reason this? i think quite logical. when you're calling custom function in cell, a1, expecting function calculation (or whatever) , place result in a1. if want see result in b1, you'd write same formula in b1. as doc explains, there might cases want function return more 1 value in case, returning 2d array populate cells adjacent 1 formula called. in case, can give use case have want populate different cell using c...

i'm trying use laravel on host has many subdomains. 1 subdoman have laravel's app running on i'd share things (like current user) via php native session. i've edited laravel's session config work subdomains, changing domain value: 'cookie' => 'mydomain_session', 'domain' => '.mydomain.com', in subdomain, laravel not running, i'm trying access session in way: session_name("mydomain_session"); session_set_cookie_params(0,'/','.mydomain.com',false,true); session_start(); but it's not working, if try echo $_session variable empty. the strangest thing if try echo session_id() it's same in both subdomains. moreover if set same script in third subdomain share session other non-laravel subdomain no problem. so i'm doing wrong? i'm missing or laravel not managing native php session in ordinary way? any appreciated! or laravel not managing native php session in o...
