rather rewriting entire contents of xml file when single element updated, there better alternative updating file? i recommend using vtd-xml http://vtd-xml.sourceforge.net/ from faq ( http://vtd-xml.sourceforge.net/faq.html ): why should use vtd-xml large xml files? for numerous reasons summarized below: performance: performance of vtd-xml far better sax ease use: random access combined xpath makes application easy write better maintainability: app code shorter , simpler understand. incremental update: occasional, small changes become efficient. indexing: pre-parsed form of xml further boost processing performance. other features: cut, paste, split , assemble xml documents possible vtd-xml. in order take advantage of vtd-xml, recommended developers split ultra large xml documents smaller, more manageable chucks (<2gb).

what '\r' mean? do? have never seen before , giving me headaches. doesnt seem have purpose, since 'a\ra' prints 'aa', not same string 'aa'. im using python 2.6 it's old control character typewriters. means "carriage return". in time, when pressed "enter", going next line, carriage went beginning of line (hence carriage return). computers, different oses made different choices represent new lines. on windows, have "\r\n" (carriage return + new line). on unices, have "\n" (no need carriage return, sort of implied new line). on old mac os, had "\r" only. nowadays, it's not used except newlines (or don't know other usages).

should keep project filesm eclipse's .project, .classpath, .settings, under version control (e.g. subversion, github, cvs, mercurial, etc)? you want keep in version control any portable setting files , meaning: file has no absolute path in it. includes: .project, .classpath ( if no absolute path used , possible use of ide variables, or user environment variables) ide settings (which disagree 'accepted' answer). settings includes static code analysis rules vitally important enforce consistently user loading project his/her workspace. ide specific settings recommandations must written in big readme file (and versionned of course). rule of thumb me: must able load project workspace , have in need set in ide , going in minutes. no additional documentation, wiki pages read or not. load up, set up, go.

this came in hidden features of python , can't see documentation or examples explain how feature works. you'd use in own class, since no builtin class makes use of it. numpy uses it, stated in documentation . examples here . in own class, you'd use this: >>> class testellipsis(object): ... def __getitem__(self, item): ... if item ellipsis: ... return "returning items" ... else: ... return "return %r items" % item ... >>> x = testellipsis() >>> print x[2] return 2 items >>> print x[...] returning items of course, there python documentation , , language reference . aren't helpful.

i'm in process of trying hack first bits of kernel. have entire kernel compiled down c code, , i've managed displaying text in console window , of fine goodness. now, want start accepting keyboard input can make use of thing , going on process management. i'm using djgpp compile, , loading grub. i'm using small bit of assembly jumps directly compiled c code , i'm happy there. all research i've done seems point isr @ $0x16 read in next character keyboard buffer. can tell, supposed store ascii value in ah, , keycode in al, or effect. i'm attempting code using following routine in inline assembly: char getc(void) { int output = 0; //crazy voodoo code asm("xor %%ah, %%ah\n\t" "int $0x16" : "=a" (output) : "a" (output) : ); return (char)output; } when code called, core crashes. (i'm running on virtualbox, didn't feel need try basic on real hard...

my code in c# asp.net 3.5 in following code "msg" has many words spaces , characters (eg:failed prepare sync favorites : directory not exist: \stl-fnp-02\ryounes$\sync\favorites). "msg" pulled database gridview. not able create hyperlink "msg" in gridview. since has spaces not creating hyperlink. i need create hyperlink "msg" , latter use in linq query. i think 1 shud either use eval or url encoder. not sure how it. can how go it? <asp:hyperlinkfield datatextfield="msg" headertext="msg" datanavigateurlfields="msg" datanavigateurlformatstring="sync.aspx?msg={0}" /> the easiest way around use <asp:templatefield headertext="msg"> <asp:hyperlink runat="server" text='<%# httputility.urlencode(eval("msg")) %>' navigateurl='<%#eval("msg")%>' /> </asp:templatefield> not 100% syntax correct...

as example, lets wanted list frequency of each letter of alphabet in string. easiest way it? this example of i'm thinking of... question how make alltheletters equal said letters without alltheletters = "abcdefg...xyz". in many other languages letter++ , increment way through alphabet, far haven't come across way in python. def alphcount(text): lowertext = text.lower() letter in alltheletters: print letter + ":", lowertext.count(letter) the question you've asked (how iterate through alphabet) not same question problem you're trying solve (how count frequency of letters in string). you can use string.lowercase, other posters have suggested: import string alltheletters = string.lowercase to things way you're "used to", treating letters numbers, can use "ord" , "chr" functions. there's absolutely no reason ever this, maybe comes closer you're trying figure out: def getallthele...

i'm trying figure best strategy how organize datacontexts. typical db work has between 50 , 100 tables in third-normal form , many relations between them. think have 2 options: put tables in single context. ensure committed in correct order in database. problem linq designer mess 50+ tables , i'm worrying performance may affected. create several data contexts based on logical grouping of tables. problem there places 1 side of relation in 1 context , other in one. we'll have manually take care of committing both context-s in correct order. is there recommended practice handle this? more details: i want create own entities , unit of work on top of linq sql. entities defined in xml model file mapping linq entities specified also. custom tool generate entities (poco) based on model. client code interact entities , unit of work; never directly datacontext or linq entities. not want duplicate linq sql provide out of box want use underlying linq datacontext. means c...

i using mock object in rhinomocks represent class makes calls messagequeue.getpublicqueues. want simulate exception thrown when message queueing operating in workgroup mode, messagequeueexception, ensure catching exception correctly the messagequeueexception has no public constructor, standard protected constructor exception. there appropriate way throw exception mock object / expect.call statement? reflection can break accessibility rulez. will void warranty, .net update can break code. try this: using system.reflection; using system.messaging; ... type t = typeof(messagequeueexception); constructorinfo ci = t.getconstructor(bindingflags.nonpublic | bindingflags.instance, null, new type[] { typeof(int) }, null); messagequeueexception ex = (messagequeueexception)ci.invoke(new object[] { 911 }); throw ex;

i need create windows service execute every n period of time. question is: timer control should use: system.timers.timer or system.threading.timer one? influence on something? i asking because heard many evidences non correct work of system.timers.timer in windows services. thank you. both system.timers.timer , system.threading.timer work services. the timers want avoid system.web.ui.timer , system.windows.forms.timer , respectively asp applications , winforms. using cause service load additional assembly not needed type of application building. use system.timers.timer following example (also, make sure use class level variable prevent garbage collection, stated in tim robinson's answer): using system; using system.timers; public class timer1 { private static system.timers.timer atimer; public static void main() { // normally, timer declared @ class level, // stays in scope long needed. // if timer declared in lo...

both document.getelementsbytagname('div') , document.queryselectorall('div') return nodelist collection. difference first method returns live-collection , second 1 - static one. the question - there opportunity distinguish 1 object via inspecting these objects (i.e - not trying add/remove items test "liveness")? thanks in advance the nodelist interface agnostic of dead or live status. interface nodelist { node item(in unsigned long index); readonly attribute unsigned long length; }; it contains property length , , method item i'm afraid it's not possible determine if object live without manipulating dom , seeing effects.

i'd warn users when try close browser window if didn't save changes made in web form. i'm using asp.net 3.5 (with asp.net ajax). is there common solution implement? edit: maybe question wasn't clear: looking way integrates gracefully in asp.net server controls methodology. here asp.net extender control this: http://www.codeproject.com/kb/ajax/ajaxdirtypanelextender.aspx hope helps. may not fit needs @ least shows how.
