c# - Object List View Highlight Renderer with Composite Filters -

-

i'm trying filter object list view composite filter (i.e. multiple filter conditions) default highlight text renderer renders text of first filter.

is there way make apply filters or better yet use multiple text renderers 1 each filter?

i'm using control characters (&& , ||) delimit search terms

some c&p code illustrate

public void filter (string txt, matchkind matchkind) {      bool filterbyall;      ienumerable<string> terms = splitsearchterms(txt, out filterbyall);      list<imodelfilter> modelfilters = new list<imodelfilter>();      foreach (string term in terms) {         imodelfilter filter;         switch (matchkind) {               case matchkind.contains:               default:                  filter = textmatchfilter.contains(_olv, term);                  break;               case matchkind.prefix:                  filter = textmatchfilter.prefix(_olv, term);                  break;               case matchkind.regex:                  filter = textmatchfilter.regex(_olv, term);                  break;            }         modelfilters.add(filter);      }       compositefilter compositefilter;      if (filterbyall) {         compositefilter = new compositeallfilter(modelfilters);      } else {         compositefilter = new compositeanyfilter(modelfilters);      }      //only highlights text first filter      highlighttextrenderer renderer = _olv.defaultrenderer highlighttextrenderer;      if (renderer != null) {         solidbrush brush = renderer.fillbrush solidbrush ?? new solidbrush(color.transparent);         if (brush.color != color.lightseagreen) {            brush.color = color.lightseagreen;            renderer.fillbrush = brush;            _olv.defaultrenderer = renderer;         }      } else {         messagebox.show(@"renderer null!");      }      _olv.modelfilter = compositefilter;   }

this solution works me. multiple columns support still highlighting support.

var filters = new list<imodelfilter>(); textmatchfilter highlightingfilter = null; if (!string.isnullorempty(txtsearch.text)) {     var words = txtsearch.text.trim().split(null);     highlightingfilter = textmatchfilter.contains(listview, words);     foreach (var word in words)     {         var filter = textmatchfilter.contains(listview, word);         filters.add(filter);     } } var compositefilter = new compositeallfilter(filters);  listview.modelfilter = highlightingfilter; listview.additionalfilter = compositefilter; listview.defaultrenderer = new highlighttextrenderer(highlightingfilter);

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
