i have usercontrol have various properties defined, can customise each copy that's on screen. have path uses lineargradientbrush fill. @ present hard coded xaml. have width , visibility of path control dependency objects , can modify these: <path visibility="{templatebinding pathavisibility}" width="{templatebinding pathalength}"> <lineargradientbrush endpoint="0,0.5" mappingmode="relativetoboundingbox" startpoint="1,0.5"> <gradientstop color="#07ffffff" offset="0.812"/> <gradientstop color="red"/> <gradientstop color="#00000000" offset="0.993"/> <gradientstop color="#ff956666" offset="0.62"/> </lineargradientbrush>... what i'd create few gradients options can select properties in wpf xaml designer.

i'm submitting form index() action of resource controller it' scaling store() method. here's code. http://paste.laravel.com/rru i'm trying dynamically change $perpage variable adjust pagination amount via select box submitted using jquery. ideas. as far know there no resource key available when opening form. index method on resource controller routed get request. because form opening post request default it's posting current uri results in request ending @ store method. if you're trying update pagination why don't send get , use query string (as paginator does).

so have 2 objects different parents , want draw line between them, how do this? know need use localtoglobal not sure how make work this. need x , y coordinates of both objects relative 1 of them, how x , y coordinates of on object relative when have different parents? thanks. conceptually need (draw dashes, solid line) parent | \ child1--child2 [some code (typed not tested)] var start:point = parent.globaltolocal(child1.localtoglobal(new point())); var end:point = parent.globaltolocal(child2.localtoglobal(new point())); parent.graphics.linestyle(1); parent.graphics.moveto(child1.x,child1.y); parent.graphics.lineto(child2.x,child2.y); [another option] var start:point = child1.getrect(parent).topleft; var end:point = child2.getrect(parent).topleft; parent.graphics.linestyle(1); parent.graphics.moveto(child1.x,child1.y); parent.graphics.lineto(child2.x,child2.y); http://help.adobe.com/en_us/as2lcr/flash_10.0/help.html?content=00001308.html http://help.adobe.

as described in pep435 , enum can defined way: class color(enum): red = 1 green = 2 blue = 3 and resulting enum members of color can iterated in definition order: color.red, color.green, color.blue . this reminds me of form in django , in fields can rendered in order declared in form subclass. implemented maintaining field counter, every time new field instantiated counter value incremented. but in definition of color , don't have formfield , how can implement this? in python 3, can customize namespace class declared in metaclass. example, can use ordereddict : from collections import ordereddict class enummeta(type): def __new__(mcls, cls, bases, d): print(d) return type.__new__(mcls, cls, bases, d) @classmethod def __prepare__(mcls, cls, bases): return ordereddict() class color(metaclass=enummeta): red = 1 green = 2 blue = 3 this prints ordereddict([('__module__', '__main_

in example, int x = 5; int y = x; x = 4; y remain 5 because x being reassigned , not manipulating object used refer in anyway. question is, said correct way of thinking it? or there duplication of memory stored in 'x' , duplication put in 'y'. primitives, unlike objects, stored directly inside variable. is, variable of primitive type not storing reference primitive, stores primitive's value directly. when 1 primitive variable assigned primitive variable, copies value. when do int x = 5; int y = x; x = 4; x sets value inside of 4, , y still has value 5 because value separate. the way 1 variable changed change variable, if both variables references 'mutable' object, , object mutated - since both looking @ same object, rather own copies, both observe same change. (note example strings, being immutable, never 'suddenly change', arrays , collections can)

so, possible have reverse animation on mouse out such as: .class{ transform: rotate(0deg); } .class:hover{ transform: rotate(360deg); } but, when using @keyframes animation, couldn't work, e.g: .class{ animation-name: out; animation-duration:2s; } .class:hover{ animation-name: in; animation-duration:5s; animation-iteration-count:infinite; } @keyframe in{ {transform: rotate(360deg);} } @keyframe out{ {transform: rotate(0deg);} } so optimal solution, knowing i'd need iterations , animation itself... thanks http://jsfiddle.net/khalednabil/ewzbm/ i think if have to , must use from . think of : @keyframe in { from: transform: rotate(0deg); to: transform: rotate(360deg); } @keyframe out { from: transform: rotate(360deg); to: transform: rotate(0deg); } of course must have checked already, found strange use transform property since css3 not implemented everywhere. maybe work better following considerations

i see there few questions regarding fabric , passwords. know if pass -i fabric password enter passed environmental variable "password." problem i'm prompted password when running ssh command on remote server remote server. but , don't want prompted password entry. prompted no matter try do. here's little snippet of code: elif "test" in run('hostname -d'): print(blue("gathering knife info")) run("ssh mychefserver knife node show `hostname`.test.dmz") it works fine when enter password. thing is, don't want have enter password. maybe because ssh connection initiated on remote host , fabric can't that. i have script disconnect remote host, run ssh command locally, reconnect remote host finish script... seems silly. suggestions? getpass info: python 2.6.6 (r266:84292, sep 11 2012, 08:34:23) [gcc 4.4.6 20120305 (red hat 4.4.6-4)] on linux2 type "help", "copyrigh

a bit of background: i working on assignment oop course consists in designing , implementing phone book manager around various design patterns. in project there 3 classes around action happens: phonebook ; contact (the types stored in phone book); contactfield (fields stored in contact ). contactmanager must provide way iterate on contacts in 2 modes: unfiltered , filtered based on predicate; contact must provide way iterate on fields. how decided implement: all design patterns books came across recommend coding interface first thought extract interface each of above classes , make them implement it. now have create kind of polymorphic iterator things smooth adapted java iterator interface write forward iterators. the problems: the major setback design lose interoperability stl <algorithm> , syntactic sugar offered range based loops. another issue came across iterator<t>::remove() function. if want iterator can alter sequence iter

i have output richtextbox (could lot or litte, search results) , apply custom color coding. decided regex , while works, seems pretty slow (~20 seconds) 300 results. the output in same format: attribute1=value1 attribute2=(value2) attribute3="string value 3" attribute4= and on. so, have 4 cases: stuff=stuff, stuff=(stuff) stuff="string of stuff" , stuff= the following regex works fine (matches should), slow: (\s+)=("(?:[^"]|(?<open>")|(?<-open>"))+(?(open)(?!))")|(\s+)=(\((?:[^()]|(?<open>\()|(?<-open>\)))+(?(open)(?!))\))|(\s+)=(\s+)|(\s+)=\s do guys see in particular that's slowing down? i'm sure can tell, first section matches quotes, second section matches parentheses, ect ect. update kidding, doesn't return want... this: attribute1=value1 attribute2=(value2) attribute3="string value 3" attribute4= attribute5="another string" returns this: 5: attribute1 6:

i'm having bit of trouble routing in .net. when i'm making redirecttoaction following code: return redirecttoaction("edit", "add", new { id = newid, someval = newsomeval }); and following maproute : context.maproute( "editstuff", "admin/{controller}/{action}/{id}/{someval}", new { controller = "edit", action = "add", id = @"\d+", someval = @"\d+" } ); i redirected url has someval parameter delimited ? instead of / , so: http://localhost:60733/admin/edit/add/43?someval=1 instead of http://localhost:60733/admin/edit/add/43/1 both links work if access them directly. can shine light on issue? many thanks!
