currently, reading data binary file (file.readallbytes), converting byte array string , appending data onto string. lastly, converting string byte array , writing data new file. yeah - method idiotic, , i've been curious whether or not there way append new data onto end of byte array (in form of byte). string s = @"c:\file.exe"; byte b[] = file.readallbytes(s); string newstring = converttostring(b[]); newstring = newstring + "some data"; b[] = converttobytearray(newstring); file.writeallbytes(b[]); // converttobytearray , converttostring represent functions converts string > byte > string. what do: b[] = file.readallbytes(s) b = b + "new data" file.writeallbytes(b[]) thank insight on matter. you should used working streams - in case use memorystream achieve exact same thing without nasty arrays. byte[] bytes = file.readallbytes(infilepath); using (memorystream ms = new memorystream()) { // use streamwriter &quo

on subclasses of view there gettag() method, returns android:tag attribute's value .xml. same menuitem ... okay cast view ? because item elements allow tag attribute in .xml... update: goal setting tag in .xml, i.e. "notranslate" , , querying @ runtime (we localize hand @ runtime, don't ask...) menuitem interface. class can implement interface , not always safe cast menuitem view. can use "instanceof" operator test see if object implements menuitem interface indeed view or not. i understand want define flag in xml definition of menu , @ run time interrogate flag make programmatic decision. the menu resource documentation records attributes can set in xml. can consider using (abusing) 1 of settings such "android:alphabeticshortcut" encode flag , use menuitem::getalphabeticshortcut() method value. not require casting - uses existing fields in menuitem xml construct/class own purposes. perhaps less hacky way keep simple tabl

just curious, possible find out, items generated while program running in stack , heap? there tool or meachanism out there identify memory usage in vs2010 c# (silverlight)? thanks, yes, can use visual studio profiler (or other profiler). tutorial: http://msdn.microsoft.com/en-us/magazine/cc337887.aspx other memory profilers: http://memprofiler.com http://www.red-gate.com/products/dotnet-development/ants-memory-profiler/ http://www.xteprofiler.com/ (supports silverlight) so question: what .net profilers?

i have function returns jsonresult in below way. var attachments = (from in ar.attachments select new { id = a.id, filename = a.filename }).toarray(); var result = new { comments = "some string", attachments = attachments }; return this.json(result); i need use result in class need access "comments" , "attachments". here attachments string array , comments string. please let me know how can this. you create viewmodel result , reuse class. viewmodel is, poco or dto. idea gives different way "look" @ data, nothing special really. so end 3 parts. the data method: public commentsviewmodel getviewmodel() { var attachments = (from in ar.attachments select new { id = a.id, filename = a.filename }).toarray(); var result = new commentsviewmodel { comments = "some string", attachments =

i have following eval(id+' = new myobject()'); and want access resulting object , methods. with myobject = eval(id); myobject.mymethod(); but elegant alternatives there using eval? assume id intended global object , you're executing in browser, window[id] = new myobject(); myobject = window[id]; myobject.mymethod(); or modify code store id object. var objectstore = {}; objectstore[id] = new myobject(); myobject = objectstore[id]; myobject.mymethod();

i'm useing sql ser 2008 , have large table 1 column of data. data random string little consistency. eample: name account 445566 0010020056893010445478008 afd 369. i've been working split function stackoverflow user suggested. works great function assigns split string 1 column. need row of individual columns. present result 1col values name, account, 445566,... in result i'm looking col1 name, col2 account, col3 445566,... if provide insight on how tailor script or usage desired result appreciated. create function [dbo].[split] ( @string varchar(max) ,@delimiter char ) returns @results table ( ordinal int ,stringvalue varchar(max) ) begin set @string = isnull(@string,'') set @delimiter = isnull(@delimiter,'') declare @tempstring varchar(max) = @string ,@ordinal int = 0 ,@charindex int = 0 set @charindex = charindex(@delimiter, @tempstring) while @charindex != 0 begin set @ordinal += 1 insert @results va

so have ten ips bound network adapter. when go add binding iis7 presents me list of ip addresses available, have 127.0.0.1. can manually enter ip address bind host headers websites. still iis function , present me of ip adresses bound adapter. any ideas how fix this? ok figured out, should stop asking questions on here seem answer lot of own. there entry in hosts file bound 127.0.0.1 hostname of computer, removing solved iis issue.

how right way call ienumerator.reset ? the documentation says: the reset method provided com interoperability. not need implemented; instead, implementer can throw notsupportedexception . okay, mean i'm not supposed ever call it? it's so tempting use exceptions flow control: using (enumerator = getsomeexpensiveenumerator()) { while (enumerator.movenext()) { ... } try { enumerator.reset(); } //try inexpensive method catch (notsupportedexception) { enumerator = getsomeexpensiveenumerator(); } //fine, 1 while (enumerator.movenext()) { ... } } is how we're supposed use it? or not meant use managed code @ all? never ; mistake. correct way iterate sequence more once call .getenumerator() again - i.e. use foreach again. if data non-repeatable (or expensive repeat), buffer via .tolist() or similar. it formal requirement in language spec iterator blocks throw exceptions method. such, cannot rely on working . ever.

i learned of nuget package loop helper webmatrix . unfortunately can't seem find documentation or project site. have information on how use or project site is? i think supplied sample pretty covers need know, loop tracker isn't mysterious might think. all loop.outerloop doing referencing parent loop if you're in 1 , it's being tracked, example: @{ int[] outerthings = new int[] {1,2,3,4}; var innerthings = new[] {"a","b","c", "d"}; foreach (int outerthing in outerthings.track()) { <li>@outerthing @foreach(var innerthing in innerthings.track()) { <li>---->@innerthing @if (loop.outerloop.first) { <strong>start of outer loop (index is: @loop.outerloop.index)</strong> } @if (loop.outerloop.last) { <strong>end of outer loop (index is: @loop.outerloop.index)</strong> } </li> }

i found snippet executing vacuum of sqlite3 db doesn't work. can tell me wrong it. sqlite3_exec(database, "vacuum;", 0, 0); thanks... ok here's solution make vacuum command work. if(sqlite3_exec(database, "vacuum;", 0, 0, null) == sqlite_ok) { nslog(@"vacuumed database"); } that makes command work app locked out of database while runs.

the php imap library doesn't have built in ways change imap_timeout function secure pop3 connections. i'm looking build functionality can set timeout 1 second connections secure pop3 servers, i'm not sure start learn overriding php.ini command within php function. ideas? imap_timeout(1, ) works fine pop3 connections, but apparently not pop3s (ssl, port 995) connections, default socket timeout still applies. applies php 4.3.10, not tested on other versions. we looked source find out function , how use it. the function overrides default_socket_timeout setting php.ini file you can retrieve current timeout length each timeout type calling function as: imap_timeout(timeout_type); or imap_timeout(timeout_type,-1); you can set timeout length of timeout types setting timeout value number of seconds. imap_timeout(timeout_type,); the timeout types follows: 1: open 2: read 3: write 4: close

suppose have list of myobject this: public class myobject { public int objectid {get;set;} public string prop1 {get;set;} } how remove duplicates list there multiple instance of objects same objectid. thanks. you can use groupby() , select first item of each group achieve want - assuming want pick 1 item each distinct objectid property: var distinctlist = mylist.groupby(x => x.objectid) .select(g => g.first()) .tolist(); alternatively there distinctby() in morelinq project allow more concise syntax (but add dependency project): var distinctlist = mylist.distinctby( x => x.objectid).tolist();
