there doesn't seem way change padding (or row height) rows in .net listview. have elegant hack-around? i know post old, however, if never found best option, i've got blog post may help, involves utilizing lvm_seticonspacing. according blog, initially, you'll need add: using system.runtime.interopservices; next, you'll need import dll, can utilize sendmessage, modify listview parameters.

when use zedgraph linegraphs , set issmooth true, lines nicely curved instead of having hard corners/angles. while looks better graphs -in humble opinion- there small catch. smoothing algorithm makes line take little 'dive' or 'bump' before going upwards or downwards. in cases, if datapoint smooth, isn't problem, if datapoints go 0 15, 'dive' makes line go under x-axis, makes seems though there datapoints below 0 (which not case). how can fix (prefably ;) no simple answer this. keeping tension near 0 simplest solution. zedgraph uses gdi's drawcurve tension parameter apply smoothness, hermite interpolation. can try implement own cosine interpolation, keep local extremes because of nature. can @ link see why: http://local.wasp.uwa.edu.au/~pbourke/miscellaneous/interpolation/ edit: website down. here cached version of page: http://web.archive.org/web/20090920093601/http://local.wasp.uwa.edu.au/~pbourke/miscellaneous/interpolation/...

i asked question in interview: string reference type or value type. i said reference type. asked me why don't use new operator while initializing string ? said because c# language has simpler syntax creating string , compiler automatically converts code call construcor of system.string class. is answer correct or not ? strings immutable reference types. there's ldstr il instruction allows pushing new object reference string literal. when write: string = "abc"; the compiler tests if "abc" literal has been defined in metadata , if not declare it. translates code following il instruction: ldstr "abc" which makes a local variable point string literal defined in metadata. so answer not quite right compiler doesn't translate call constructor.

i'm using vs2010, asp.net mvc 2, , resharper 5.0. when create new view that's typed off of model same project view, resharper doesn't see reference model. this definition of view: <%@ page language="c#" inherits="system.web.mvc.viewpage<web.domain.userviewmodel>" %> domain.userviewmodel red, , reshaper tooltip add reference pops up. annoying because cannot use intellisense model , resharper shows numerous errors in view. this strictly resharper code-inspection issue. view functions if run code. if change web.domain.userviewmodel object project red dissapears , fine. know how can make recognize models web project correctly? did try latest bug fix update, resharper 5.1?

for major browsers (except ie), javascript onload event doesn’t fire when page loads result of button operation — it fires when page first loaded. can point me @ sample cross-browser code (firefox, opera, safari, ie, …) solves problem? i’m familiar firefox’s pageshow event unfortunately neither opera nor safari implement this. guys, found jquery has 1 effect: page reloaded when button pressed. has nothing " ready ". how work? well, jquery adds onunload event listener. // http://code.jquery.com/jquery-latest.js jquery(window).bind("unload", function() { // ... by default, nothing. somehow seems trigger reload in safari, opera , mozilla -- no matter event handler contains.

in objective-c properties can set alternative names fpr accessors. @property(setter=namewrite:,getter=nameread,copy) nsstring *name; i thinking real hard don't know situation ever that. not kvc standard , see no advantage @ all. use of it? mostly, used bool properties: @property(getter=ishidden) bool hidden; @property(readonly, getter=isfinishedlaunching) bool finishedlaunching; but, yeah, beyond that, isn't used @ (nor should be).

i have tabhost number of tabs need access same service through out life of application. 'best practice' suggests unbind services when pausing activity, mean disconnecting service, reconnect on selection of next tab, daft (not least because service maintains connection server). store reference service in tabhost, don't know how reference tabhost child activities. alternative extend application class , manage service there. does have better ideas or reasons why shouldn't either of above? thanks extending application class alternative. however can extend activity , make child activities inherit extended activity, way implement same code (service handling) in 1 activity(the parent). activity -> myparentactivity -> mychildactivity1

in terms of speed/memory efficiency, make sense save element (retrieved via $) variable in object or use $ access each time? does accessing object properties (especially if nested few levels - object within object) perform faster using $? caching selectors used idea. namespacing behind several levels deep object creates longer neccessary global scope chain, imo. tend cache selectors within simple closures or via using mootools' element storage. for example, if have link in div locates parent, finds 2 elements down , first img , can see user clicking multiple times, can this: document.id("somelink").addevent("click", function() { var targetimg = this.retrieve("targetimg") || this.store("targetimg", this.getparent().getnext().getnext().getelement("img.close")); targetimg.fade(.5); ... }); on first click target img , store under link's storage key targetimg , subsequent clicks use stored reference. moot...
