i want read word document in server (both doc , docx). server not have office installed, therefore can't use com objects , no commercial softwares. is there way can use office tools alone , read word docs (2003 , 2007) unfortunately there no free options reading .doc , .docx files. commercial options sparse @ reasonable prices, there extremely expensive options. for reading .doc files free option i'm aware of poi java can run in .net using ikvm. however, word support in experimental branch of poi's svn repository, don't know how works. http://poi.apache.org/ http://www.ikvm.net/ if want text out of .doc file , don't care formatting, can use ifilter win32 interface through pinvoke. for reading .docx files can use microsoft office open xml sdk. don't let "sdk" fool though, light abstraction on dealing xml directly. it's painful use. http://www.microsoft.com/downloads/en/details.aspx?familyid=c6e744e5-36e9-45f5-8d8c-331...

what going on here? when thought knew js inside , out, gem comes up. string.prototype.donothing = function() { return this; }; alert(typeof 'foo'.donothing()) // object alert(typeof 'foo') // string http://jsfiddle.net/djbmf/ this breaking things expect string, such jquery's .text(str) method. here's thorough overview of this keyword. basically, javascript converts object, if wasn't one. the following steps performed when control enters execution context function code contained in function object f, caller provided thisvalue, , caller provided argumentslist: if function code strict code, set thisbinding thisvalue. else if thisvalue null or undefined, set thisbinding global object. else if type(thisvalue) not object, set thisbinding toobject(thisvalue). else set thisbinding thisvalue same thing happens numbers , booleans. similar donothing function return type of object.

what's efficient way convert ienumerable<t> idictionary<u, ienumerable<t>> where u is, example guid, information held in property of t. basically, creates dictionary of lists items in original list grouped based on value in property within objects. example object definition: class myobject { public guid uid { get; set; } // other properties } start with: ienumerable<myobject> listofobj; end with: idictionary<guid, ienumerable<myobject>> dictoflists; whereby listofobj contains objects have many different, overlapping values uid property. using linq: var dict = input.groupby(elem => elem.identifier) .todictionary(grouping => grouping.key, grouping => grouping.select(x => x));

possible duplicate: an efficient way save array , keys database is there maybe serialize() equivalent returns binary? saving data strings inefficient in both ways: inefficient in manner of performance , memory. there function return pure data ram , accordingly function read back? if trying more compact representation of serialized string, e.g., 1 uses less space plain serialize() , might use gzdeflate() compress plain-text output: $data = gzdeflate(serialize($some_array)); // store in database... // restore array: $data database, then: $array = unserialize(gzinflate($data)); instead of gzdeflate() / gzinflate() , can use gzcompress() / gzuncompress() , these produce larger strings include additional metadata such checksum.

can tell me in c# why char takes 2 bytes although can stored in 1 byte. don't think wastage of memory. if not , how 1-byte used? in simple words ..please make me clear use of 8-bits.!! although can stored in 1 byte what makes think that? it takes 1 byte represent every character in english language, other languages use other characters. consider number of different alphabets (latin, chinese, arabic, cyrillic...), , number of symbols in each of these alphabets (not letters or digits, punctuation marks , other special symbols)... there tens of thousands of different symbols in use in world ! 1 byte never going enough represent them all, that's why unicode standard created. unicode has several representations (utf-8, utf-16, utf-32...). .net strings use utf-16, takes 2 bytes per character (code points, actually). of course, 2 bytes still not enough represent different symbols in world; surrogate pairs used represent characters above u+ffff

"" : $matches[0]; } if working on html snippets using phpquery/querypath still possible, adds more post-processing.

possible duplicates: what javascript snippet mean? location of parenthesis auto-executing anonymous javascript functions? (function(){ //something here... })() <--//this part right here. what )() ? if change ()) ? (function(){ //something here... }()) <--//like this declares anonymous function , calls immediately. the upside of doing variables function uses internally not added current scope, , not adding function name current scope either. it important note parentheses surrounding function declaration not arbitrary. if remove these, error. finally, can pass arguments anonymous function using parentheses, in (function (arg) { //do arg })(1); see http://jsfiddle.net/eb4d4/
