i have started ruby on rails 3 project make online version of newspaper. front page has news headlines, sports headlines , life headlines. has headlines different sections of site. all stories stored in 1 table , photos in table. simple set up. trying dry can't seem avoid it. on index action page have sports stories , on sports action page have sports. my question should make different controller every category? or have main controller categories actions?

i writing simple ui application on windows mobile 5, want display editbox user color in whole edit box not successful approach........ whenever catch window event edit control , call setbkcolor(), display text area given color not entire edit box. i want given color displayed user when window presented user not when user enters data in edit box. please let me know solution , again native win32 application code not mfc regds suhail setbkcolor sets background colour text. change background of entire control, need process wm_ctlcoloredit message , return brush of choice. can in wndproc this: (assuming hedit handle of edit control) case wm_ctlcoloredit: if ((hwnd)lparam == hedit) { hdc hdc = (hdc)wparam; setbkmode(hdc, transparent); return (lresult)getstockobject(black_brush); // or other brush want } break; by setting background mode transparent, don't need separate setbkcolor call -- text painted transparently on background.

i've been working opengl year now, , have learned lot of stuff. unfortunatly way learned old pre 3.x way, meaning immediate mode, default shaders, matrix stacks, etc. more or less have idea of has changed looking @ opengl specs, don't totally understand of new ways things. from understanding got rid of matrix stacks, meaning have keep track of own transformation matrices, doesn't seem complicated. got rid of immediate mode, meaning need use vbos or vaos (never know one, maybe both..) send pixel/normal/texture,etc. information shader program. don't way these objects works, think need put info them, , provide ofset of sort show separators between pixel,normal , texture coordinates. briefly explain how works (or send me link explains it)? tried wikipedia , googling it, found myself still not quite understanding them. another point know more shaders, i've never used them. i'm not going ask how code them or anything, needs go in there , opengl still you. more...

this regex: str.replace(/ +/g, '-').tolowercase(); will convert this: the dog jumped on lazy - chair into this: the-dog-jumped-over-the-lazy---chair how modify produces instead (only single hyphen): the-dog-jumped-over-the-lazy-chair i assume actual input "the dog jumped on lazy - chair", spaces around hyphen getting converted, since there's no other reason pattern should match there. try this: str.replace(/( +- *)|(- +)|( +)/g, '-').tolowercase(); that explicitly checks strings of spaces on either side of hyphens (the first pattern designed consume trailing space), consuming 1 hyphen in process. if hyphen exists surrounded spaces, hyphen included in match, when hyphen written, "replacement"; in case, spaces removed, , hyphen re-created replace operation because captured part of expression.

i have acces file forms create excel file multiple spreadsheets , have task converts c# application same thing vba code , has alot of code can convert vba code (e.g .dll file) enable me use vba methods in c# or anyway use vba code in c# instead of convert ? thanks, mohammed thabet zaky http://thabettech.blogspot.com/ if want yourself, possible reference com stuff. did application utilized vba (autocad). ended doing creating .net class referenced com interop , copied of code project. how created .dll file. refactored vba code c#. the copy , paste isn't seemless. need make adjustments. example thisworkbook, activesheet, , of items referenced automatically don't work automatically (because not out of excel's process). (at least us) better re-creating logic. here link reference material - http://au.autodesk.com/?nd=e_class&session_id=5084 . references autocad, doing in excel similar. hope helps.

i can not figure out algorithm task, maybe have idea? task: move array array in first half elements of odd lines , second elements of pair of lines. simplest option move elements array, make 1 using temp variable? input data array = {1,2,3,4,5,6,7,8} output data array = {2,4,6,8,1,3,5,7} is homework? if not, use std::stable_partition() : struct iseven { template<class t> bool operator()(const t& v) const { return v % 2 == 0; } }; int* arr = {1,2,3,4,5,6,7,8}; int* mid = std::stable_partition(arr, arr+8, iseven()); if homework, instructor expects write algorithm. if don't have maintain ordering in input sequence can rather efficiently: find first element doesn't satisfy predicate (i.e., odd ). find last element does satisfy predicate (i.e., even ) swap 2 elements. repeat, starting positions found, until 2 positions meet. the point 2 positions meet middle of partition, numbers stop , odd numbers begin. this how std::partition(...

if have variable (on stack) , left or right bit shift beyond end happens? i.e. byte x = 1; x >> n; what if x pointer memory cast byte , same thing? byte* x = obtain pointer somewhere; *x = 1; *x >> n; it not (necessarily) become zero. behavior undefined (c99 §6.5.7, "bitwise shift operators"): if value of right operand negative or greater or equal width of promoted left operand, behavior undefined. (c++0x §5.8, "shift operators"): the behavior undefined if right operand negative, or greater or equal length in bits of promoted left operand. the storage of value being shifted has no effect on of this.

i'm new development , want learn javascript , c#, 1 think best start with. want build web apps. they're not mutually exclusive. javascript client-side programming (dom manipulation, effects, ajax). c# server-side programming (database communication, oo, external services, etc). you should learn both. (and asp.net mvc while @ it).

i've seen syntax on variable before , not quite sure is: $script:foo = "bar" the syntax $script:foo commonly used modify script-level variable, in case $foo . when used read variable, $foo sufficient. example rather write this: verbose-script.ps1 $script:foo = '' function f { $script:foo } i write (less verbose , functionally equivalent): script.ps1 $foo = '' function f { $foo } where $script:foo crucial when want modify script-level variable within scope such function or anonymous scriptblock e.g.: ps> $f = 'hi' ps> & { $f; $f = 'bye';$f } hi bye ps> $f hi notice $f outside scriptblock did not change though modified bye within scriptblock. happened modified local copy of $f . when don't apply modifier script: (or global: ), powershell perform copy-on-write on higer-scoped variable local variable same name. given example above, if wanted make permanent change $f , use modifier script:...

how can cursor focus on specific input box on page load? is posible retain initial text value , place cursor @ end of input? <input type="text" size="25" id="myinputbox" class="input-text" name="input2" value = "initial text" /> there 2 parts question. 1) how focus input on page load? you can add autofocus attribute input. <input id="myinputbox" type="text" autofocus> however, might not supported in browsers, can use javascript. window.onload = function() { var input = document.getelementbyid("myinputbox").focus(); } 2) how place cursor @ end of input text? here's non-jquery solution borrowed code another answer . function placecursoratend() { if (this.setselectionrange) { // double length because opera inconsistent // whether carriage return 1 character or two. var len = this.value.length * 2; this.setselectionrange(len, l...

i new sql/oracle, , wondering if there's easy way parse csv string , replace tokens string. for example, have string like param,value1,str1,param,value2,str3,param,value3 and want replace value after param constant so, string become param,constant,str1,param,constant,str3,param,constant thanks in advance. you can try regexp_replace select regexp_replace(regexp_replace(regexp_replace( str,'[^,]*','constant',1,3),'[^,]*','constant',1,9),'[^,]*','constant',1,15) (select 'param,value1,str1,param,value2,str3,param,value3' str dual); if have messy (like quoted values including commas) break. said regular expressions aren't strong point , should eb able better job. i presume know having rdbms oracle , storing data in such odd manner pretty poor idea. if not going convetional table/column structure, can use object relation features or xml.
