(i can live this) possible change properties (image sources, colors, visibility, widths, etc.) @ runtime? b. (most desirable) possible –in addition previous item- add/remove elements report @ runtime? 3.- self-adjusts when resize page: a. (least desirable) have manually resize things dynamically accessing report structures (related 2a) b. (mos...

the title says all: there way set c# readonly auto-implemented propeties through reflection? typeof(change) .getproperty("changetype", bindingflags.instance | bindingflags.public) .setvalue(mychange, change.changetype.transform(),null); this line gives me error : system.argumentexception - {"property set method not found."} . thing can't use getfield because there no fields. before ask, i'm doing because need "complement" finished library , have no access code. this should work, there not telling us. sure it's auto-implemented property? explanation consistent seeing property not auto-implemented , not have setter. that is, public class foo { public int bar { get; set; } } typeof(foo).getproperty("bar").setvalue(foo, 42); will succeed but public class foo { public int bar { { return 42; } } } typeof(foo).getproperty("bar").setvalue(foo, 42); will not , produce exception message seeing....

this perfect solution me need serve generated content web browsers. plan generate content on demand , store next time. don't want browsers call service (which generates content) every time. want them go directly "cached" resource if it's available , call service if it's not. i'd put varinsh in front of server runs service , server b stores generated content versions. if gets request resource hasn't got cached it'll try server b. upon getting 404 response it'll request same resource server a. can varnish configured in such way vcl? if not there solution know about? p.s. don't want send 302 redirects browser plus don't have control on server b make send such redirects instead of 404's this possible in varnish. make sure in vcl_fetch (and possibly in vcl_error) check return status code (e.g. check status > 400), restart if failed, , in vcl_recv select other backend if req.restarts > 0. example: backend servera { ...

if virtualise 4 servers on 1 hardware (for instance 3 tomcat servers on same physical machine) can terminate 3 different ip addresses, hence 3 different http address same physical machine? i'm trying use temporary solution hosting same service 3 different departments pending software redesign solution , how viable solution. second question vm hardware setup kind of scenario? past readings topic suggests there 2 ways achieve virtualisation, work best? answers in advance. (researching possibilities mean time) yes, can have 3 different ip addresses. each server present network physically separate device. as far hardware, highly dependent on storage, load, , other requirements of these virtual servers be. but, you'll want fast storage, lots of ram, , decent multicore processor. look requirements of vmware esx. believe it's open source , can implemented free in non-commercial settings (but might not qualify sure check). this article couple of years old might...

i've git repository administered gitosis on server. on same server have teamcity ci. i can't seem connect git repository through teamcity. i've administrator user can access repository (its under git user on same server) through cygwin, when try setup teamcity access administrator's private key authentication issue: 'connection test failed: com.jcraft.jsch.jschexception: auth fail'. in team city have username style email, authentication method private key, username same public key , path private key correct. when using password access i'm told path doesn't git repository, though , works fine through cygwin. if has teamcity connecting gitosis repository please let me know how managed it. i've solved problem.... using wrong user type. using user name not user name email.

i'm having problem using validation rule in data grid: i want use validationrule on datagridcomboboxcolumn, used this example for guidance, in particular bindinggroup stuff. this works extent seems broken. validatiorule doesn't fire combo box selection changes, instead fires when change selection click on row in datagrid. need fire have changed selection of combo box. i've tried messing validation step no avail, can help? thanks in advance! you need change default updatesourcetrigger property combobox . updatesourcetrigger=propertychanged if still doesn't work check out this post details way take care of selection change not being forced model.

i changed structure of page urls of 1 of websites using url rewriting , need redirect old structure new 1 (to handle old links indexed google). problem want redirect rewritten url, not actual url , cannot find way this. before changes had following urls: rewriterule ^products/([^_\r\n//]*)/([^_\r\n//]*)/$ /products.aspx?cat=$1&subcat=$2 [nc,l] after changes, have following: rewriterule ^products-([^_\r\n//]*)-([^_\r\n//]*)/$ /products.aspx?cat=$1&subcat=$2 [nc,l] what want issue 301 redirect urls match ^products/([^_\r\n//]*)/([^_\r\n//]*)/$ ^products-([^_\r\n//]*)-([^_\r\n//]*)/$, ie, have following rule: rewriterule ^products-([^_\r\n//]*)-([^_\r\n//]*)/$ products-([^_\r\n//]*)-([^_\r\n//]*)/ [nc,l] the above rule produces following error: "the page isn't redirecting properly" is there way .net or using url rewrite rules? any grately appreciated. ok, fixed problem using following rule: rewriterule ^products-([^_\r\n//]*)-([...

i want compare local master branch remote origin/master branch. know how git pull --rebase; git diff origin/master local master branch detect line-by-line differences in code. but, want compare commit histories, i.e., show git log , git log origin/master side-by-side. tried git show-branch -a got: * [master] change content background-color blue ! [origin/head] add favicon ! [origin/master] add favicon --- * [master] change content background-color blue *++ [origin/head] add favicon is there better way? also, head point to, checked-out commit? you do: git log master..origin/master to list commits "between" master , origin/master . head points checked out commit. both dot-dot syntax , head documented @ gitrevisions(7) .

for example: list = [{"title_url": "joe_white", "id": 1, "title": "joe white"}, {"title_url": "peter_black", "id": 2, "title": "peter black"}] how can efficiently loop through create: joe white, peter black <a href="/u/joe_white">joe white</a>,<a href="/u/peter_black">peter black</a> thank you. the first pretty simple: ', '.join(item['title'] item in list) the second requires more complicated, same: ','.join('<a href="/u/%(title_url)s">%(title)s</a>' % item item in list) both use generator expressions , similar list comprehensions without need list creation

i want create real time game. game have model updated periodically... - (void) timerticks { [model iterate]; } like games, revive user input events, touches. in response need update model.... - (void)touchesbegan:(nsset *)touches withevent:(uievent *)event { [model updatevariableinmodel]; } so there 2 threads: from timer. iterates model from ui thread. updates the model based on user input both threads sharing variables in model. what best practice sharing objects between threads , avoiding multi threading issues? lock objects need shared across thread using @synchronized keyword. an easy way lock objects this: -(void) iterate { @synchronized(self) { // thread safe } } -(void) updatevariableinmodel { @synchronized(self) { // use variable pleased, don't worry concurrent modification } } for more info on threading in objective-c, please go here also note must lock same ...

i making kind of anti-hack thing program, , want able create checksum of bytes of function see if has been modified. know how checksum, how how many bytes should checksum? there way size of function? don't try. cannot assume function contiguous in memory: may have basicblocks lower start addresses entrypoint; may share trailing basicblocks other functions; may contain interspersed data or alignment bytes or may disappear entirely, depending on calling site (due compiler deciding inline function). there no way code know size of generated function. think it: size entirely dependent on compiler emits , depends on kinds of compiler settings , flags (think optimizing, heavily inlined release build vs debug build or using enhanced instruction sets sse vs not using them). also, indicated, such checksum check trivial work around hacker - branch have invert. and lastly, exercise curious , because potential malicious hackers use too, i'd recommend locking @ binary v...

i trying use uialertview label (no title or buttons, display text) aesthetic purposes. want able continue use else in app (touch other buttons, etc.) while alert view being shown. unfortunately, cannot seem invoke touchesbegan or selector using uitapgesturerecognizer while alert view shown. these both work when alert view not shown, seems alert view disables detection of touches (other touching own buttons if had them). does know way work around this? if create uilabel , set background alert view image work. thanks help. the alert view puts new window on top of entire screen intercepts touches. it's expressly designed prevent doing you're trying do. why trying abuse alerts in manner anyway? it's bad idea take existing ui , use them in non-standard ways, possible reason rejected. your best bet draw "alert view" yourself, either in code or pre-baked image. unfortunately means cannot leverage built-in code draws uialertview, it's best don...

i have code handles exception, , want specific if it's specific exception, , in debug mode. example: try: stuff() except exception e: if _debug , e keyboardinterrupt: sys.exit() logging.exception("normal handling") as such, don't want add a: except keyboardinterrupt: sys.exit() because i'm trying keep difference in debug code minimal well, really, should keep handler keyboardinterrupt separated. why want handle keyboard interrupts in debug mode, swallow them otherwise? that said, can use isinstance check type of object: try: stuff() except exception e: if _debug , isinstance(e, keyboardinterrupt): sys.exit() logger.exception("normal handling")

i relatively new assembly. read string command line, store in variable , convert integer. ideas? tutorial using used assembly code didn't want use in of assembly applications doing. running linux ubuntu x86 processor. "read" syscall. can set registers (linux) or stack (freebsd) , use syscall raising interrupt or use nasmx 's macros (in cross-platform way!). stdin, stdout, , stderr file descriptors 0, 1 , 2 respectively. or, use scanf in same way (which of course provided in standard c library , call read you). it's easier unless want write own integer parser no reason!

i'm running weird behavior app i'm using. if start command in background in bash, can kill using $ command & $ kill -n 2 [pid of command] killing command gracefully however, when throw script: command & id=$! kill -n 2 $id it doesn't @ all. there subtly i'm missing? edit: clue once script stops running, can't kill command using kill -n 2. man 7 signal sending signal 2, int, process, interrupt keyboard, why ? people saying send signal 1, why ? the standard gracefully way kill process signal 15, termination sigal, default used kill. so use kill "$pid" then, in case process run subprocess, don't want kill father, want kill them all, use "-$pid" instead of "$pid" kill whole process group, kill think that's -"$pid" signal number, complain, you'll have more precise, : kill -15 -"$pid" if program don't want die, use kill -9 -"$pid" man 7 signal man kil...

i've been getting more , more high-level application development javascript/jquery. i've been trying learn more javascript language , dive of more advanced features. reading article on memory leaks when read section of article. javascript garbage collected language, meaning memory allocated objects upon creation , reclaimed browser when there no more references them. while there nothing wrong javascript's garbage collection mechanism, @ odds way browsers handle allocation , recovery of memory dom objects. this got me thinking of coding habits. time have been very focused on minimizing number of requests send server, feel practice. i'm wondering if don't go far. unaware of any kind of efficiency issues/bottlenecks come javascript language. example i built impound management application towing company. used jquery ui dialog widget , populated datagrid specific ticket data. now, sounds simple @ surface... lot of data being passed around here....

i have site hat lists set of files can downloaded. custom attribute doctype set based on file extension. if there no extension doctype set "unknowndoc". css file looks similar this: .titlecolumn[doctype="pdf"] { background: url("/images/common/icons/pdf.png") no-repeat left center; } .titlecolumn[doctype="doc"], titlecolumn[doctype="docx"] { background: url("/images/common/icons/word.png") no-repeat left center; } .titlecolumn[doctype="unknowndoc"] { background: url("/images/common/icons/unknowndoc.png") no-repeat left center; } it's quite possible user upload document don't have css style set yet. in case item have doctype no background-image. in these cases want unknowndoc style applied. use following: $('.titlecolumn').each(function (index) { var hasnodocimage = $(this).css("background-image") == "none"; var doctype = $(this).attr(...

with maven possible have top-level project who's packaging type "war" build , of dependent modules (packaged jar) , have build generate project.war file? much of documentation examples , other examples i've seen use top-level project packaging type of "pom" , project serves purpose of tying modules together. can avoid this? so need declaring <module>my-module</module> maven build, , in same pom, declaring <dependency>...my-module's artifact...</dependency> on same module needs built. maybe plugin suggested? update : in other words (to simplify problem): if have project a , project b , project a depends on project b - there way me execute build on project a , have automatically build project b (and include project b dependency - creating projecta.war contains projectb.jar)? that's not top-level project for. war project has dependencies, artifacts (e.g. jars) included in war (in web-inf/lib) when ru...

i having following issue: i have uinavigationcontroller uinavigationbar changes title switch 1 view next. example, first view called root , next view called login. first time (and first time only) call [navigationcontroller pushviewcontroller:loginviewcontroller animated:yes], login view comes in , "login" title appears on nav bar after view has appeared. because set title in function called didshowviewcontroller. need call same function willshowviewcontroller. problem uinavigationitem new view controller has not been created yet cannot set title... how around issue? thanks, franck- you should setting title of navigation item in view controller's viewdidload or loadview method, rather uinavigationcontroller delegate methods. setting title property of view controller after creating should trick, however.
