i need recursively move through bunch of custom views of mine extend view class. e.g. viewone.java viewtwo.java viewthree.java i have created instances of each view in mainclass.java viewone vone; viewtwo vtwo; viewthree vthree; these views implement function called start() . and want able loop through them somehow: for(int i=0; i<= 2:i++) { views[i].start(); } how go doing this? the above example. real reason need able move through them numerically , programatically because want able add , remove views layout in numeric order button (previous , next) clicked. (i don't want them added layout @ start because heavily resource intensive views). so required such: click next -> add next view -> remove current view. click previous -> add previous view -> remove current view. e.g. currview = 1 current view currview (1) click next add view currview+1 (2) layout switch view currview+1 (2) remove view currview (1) or currview = 2 current vie...

in pretty basic studying exercise using linkedlist , when needed return last element mistakingly used method last() instead of property last , started wonder. this method extension method of ienumerable, if it's not overloaded (visual studio + resharper displaying me basic ienumerable extension method signature method), inefficient. the linkedlist msdn page specifies of extension methods "overloaded." i'm not sure means(clicking method link displays basic method's explanation) , why doesn't visual studio + resharper show me. thanks. an easy mistake make confuse over loading over riding . when msdn page saying methods overloaded, means there multiple versions of methods different parameters. you cannot override extension methods since static.

"selection color" part of nine-patch image, provided on platform specific basis. use standard orange color, (sense) uses green, , others use red. exhaustive list of these might able create mapping hardware color, not effective because new hardware comes out time, , of these phones allow sense uninstalled. the real thing can make buttons consistent within ...

i'm trying serialize hashset i'm having no luck. whenever try open serialized data, empty hashset. however, list works fine. example code: [serializable()] public class myclass : iserializable { public myclass(serializationinfo info, streamingcontext ctxt) { hashset<string> hashset = (hashset<string>)info.getvalue("hashset", typeof(hashset<string>)); list<string> list = (list<string>)info.getvalue("list", typeof(list<string>)); console.writeline("printing hashset:"); foreach (string line in hashset) { console.writeline(line); } console.writeline("printing list:"); foreach (string line in list) { console.writeline(line); } } public void getobjectdata(serializationinfo info, streamingcontext ctxt) { hashset<string> hashset = new hashset<string>(); h...

i'm writing 2d graphics tool in c# , wpf, , i'm using adorners on shapes drawn canvas . i'd adorners highlight when shape considered "selected", i'm doing using mousedown , mouseup events. however, user can select multiple shapes, not of shapes receive both of mouse events. i have class manages drawing, holds list of selected shapes. best way give adorners access data, can see if adorned element selected? some thing's i've considered: making list global - bad idea sub-classing each shape add "selected" property - require changing references shapes in class you can make attached dependencyproperty set on shape - can set property when select one. adorner can have visibility binding property on shape visibility set automatic. you can use tag property on shape store values - old way of doing :)
