(this not modularity between assemblies modularity between simple c# classes/objects) application ( c# ) can divided following parts: components (display results , stuff) worker classes work (other thread form or component) main form (agent between components , worker classes using events , delegates) components , worker classes don't have using dependencies other namespace or class except ones framework. can't use framework types anymore. need custom classes. how share custom types between parts of application without breaking modularity ? common techniques ? edit: i'm trying use simple types int , float , string , point , pointf , arrays of of them. need add time stamps, quality values, ... can't convert them because data handled components big , performance must-have

in windows application, have pdf file stored in database. problem is, when try open pdf file, error adobe reader not open 'tem1.pdf' because either not supported file type or because file has been damaged but when open downloaded pdf normally, not give error. getting error when try open them through application. the code try open pdf files stored in database follows: private void lstbookparts_selectedindexchanged(object sender, eventargs e) { if (lstbookparts.selecteditems.count > 0) { wicommonfunction.loadcommonsettings(); showinformation showdata = new showinformation(); string item = lstbookparts.selecteditems[0].text; string book = bookname; calculatecount(book); dataset ds1 = showdata.showbookpdf(item); datatable dt1 = ds1.tables[0]; filestream fs = null; var index = lstbookparts.selectedindices; int32 = (int32)(index[0]

given url - how can make ajax query (on page load) url above , insert content returned in empty div tag on html page? <div id="ajax-result"></div> i have tried .load method jquery not working var url jquery(function($) { $('#ajax-result').load('url'); }); any ideas? due same origin policy , can't make ajax calls domain different of code. a possible solution proxy request through server side script on domain. you'd make ajax call own domain, invoke script request other domain via server server communication. third party give response server side script, in turn can pass response on through ajax response.

i have found c , rbind class of result based on class of first argument. has caused problem me because presence of na first argument coerces date vectors numeric vectors. compare result of these 2 class calls: x <- sys.date() y <- na class(c(x, y)) # "date" class(c(y, x)) # "numeric" and likewise rbind : x <- data.frame(column=sys.date()) y <- data.frame(column=na) class(rbind(x, y)$column) # "date" class(rbind(y, x)$column) # "numeric" how can ensure result of these concatenations date vector, regardless of order of arguments? coerce first argument desired class: c(as.date(y), x) c(as.date(x), y)

i wondering method of simplifying script, because somehow repeating myself on again... $('.userprofile').click(function(){ card_profile.load(url_settings).dialog('open'); }); $('.cust-profile').click(function(){ card_profile.load(url_customer).dialog('open'); }); $('.my-profile').click(function(){ card_profile.load(url_my).dialog('open'); }); var obj = { '.userprofile' : url_settings, '.cust-profile': url_customer, '.my-profile' : url_my }; $.each(obj, function(sel, url) { $(sel).click(function(){ card_profile.load(url).dialog('open'); }); }); or $(".userprofile,.cust-profile,.my-profile").click(function() { var url = $(this).hasclass("userprofile") ? url_settings : $(this).hasclass("cust-profile") ? url_customer : url_my; card_profile.load(url)

int a=1,b=2,c=3; int x=1; int y=10; = x ? b : c; cout<< a; // outputs 2 (the value of b) = y ? b : c; cout<< a; // outputs 2 (the value of b) now, @ following. a=0; x=0; = x ? b : c; cout<< a; // outputs 3 (the value of c !!!!) why unusual behaviour ?? when , x both 0, expression evaluates false , otherwise, true . please explain. because x 0. recall ternary operator, if written condition ? : b returns a if condition true , b otherwise. using numbers, , number except 0 considered true boolean. x ? b : c in case 0 ? 2 : 3 , , since 0 false , evaluates 3. 3 gets assigned a variable , printed - nothing unusual going on here.

the 'comment' field has 'id' , 'class', can't give unique 'id' because coming database (dynamic output). have tried 'toggle' (hide , show) jquery, when click particular 'comment' field of form (textarea) appearing (toggling). how toggle particular field same id or class? $(".commentform").hide(); $(".askforcomment").click(function(){ $(".commentform").toggle(); }); <div id='comments'> <div id='askforcomment' class='askforcomment'>comments?</div> <div id='viewcomments'></div> <form id='commentform' class='commentform'> <textarea cols='20' rows='2'></textarea> <input type='button'> </form> </div><!-- element looped (dynamic) --> you should target specific .commentform here : $(".askforcomment").cli

i trying rotate vector [x,y] around origin such when rotation completed lies on x axis. in order this, i'm first computing angle between [x,y] , [1,0] , applying simple 2d rotation matrix it. i'm using numericjs work vectors. math.anglebetween = function(a, b) { var x = numeric.dot(a, b) / (numeric.norm2(a) * numeric.norm2(b)); if(math.abs(x) <= 1) { return math.acos(x); } else { throw "bad input anglebetween";

i created simple class has attributeusage attribute. when tried build got error: attribute 'attributeusage' valid on classes derived system.attribute . then made class inherits attribute , fine. if use attributeusage attribute forces me inherit attribute class. question can make attribute forces methods have specific signature? thanks help! if understand correctly: looking tool controls compilation attributes. may check if stylecop or fxcop fit needs. alternatively might extend visual studio access source code model. extension may check source code (see http://blogs.msdn.com/b/sqlserverstorageengine/archive/2007/03/02/using-visual-studio-s-code-model-objects-for-code-base-understanding.aspx ), evaluates attributes , generate compiler warnings, errors whatever like. =================================== original answer: answer: have provide corresponding constructor [attributeusage(attributetargets.all)] public class helpattribute : system.attribute

so have button, , when clicked image shown, if page refreshed image disappears, , don't want that. how image stay when page refreshes. here image show function: <script> function showimage() { $("#loadingimage").show(); }; </script> and here button: <input name="failure analysis lab" style="white-space:normal;" onclick="movetext(this.name);showimage();form1.submit() " style="width: 272px; height: 30px;" type="button" value="7qkd failure analysis lab" /> you can use sessionstorage this. in init: var isimage = sessionstorage.getitem('isimage'); if (isimage !== null) showimage(); function showimage() { sessionstorage.setitem('isimage', '1'); $("#loadingimage").show(); }; if image has been shown value stored in temporary storage (will erased when browser closed - if want permanent use localstorage ins

how can next bottom element (id, class) of selected tile without loop through whole tilemap? e.g.: tile $('.gq_tiletype_4') rock in game , should fall down if next bottom tile $('.gq_tiletype_8') space is. loop throug whole tilemap , compare elements against there xy coordinates. think wrong way, because game performance slowing down. gamequery gives unique id each tiles constructed in following way: $.gamequery.tileidprefix+name+"_"+row+"_"+column this means if tilemap called "foo" can access tile @ position (a,b) writing: $("#"+$.gamequery.tileidprefi+"foo_"+a+"_"+b); in same way can deduce position (index-wise) of tile parsing it's id. means given tile can find it's position , probe state of tile bellow. how ever i'm not sure using tile-maps best solution since not supposed change. @ moment shouldn't cause problems cannot guaranty in future version wont break functions
