c# - Converting XML To dictionary -


i converting xml:

<root>     <item id="1" level="1" />     <item id="2" level="1">         <item id="3" level="2" />         <item id="4" level="2" >             <item id="5" level="3">                 <item id="6" level="4" />             </item>         </item>         <item id="7" level=2" />     </item> </root>

into dictionary using this:

xelement root = xelement.parse(strserializedoutput); dictionary<int, pair> list = root.descendants("item").todictionary(x => (int)x.attribute("id"), x => {     var pid = x.parent.attribute("id");     var depthlevel = x.attribute("level");     if (pid == null)     {         return new { parentid = 0, level = (int)depthlevel };     }     else     {         return new { parentid = (int)pid, level = (int)depthlevel };     } });

where pair is:

    public class pair     {         int parentid;         int level;     }

output want be:

id | parentid  | level ------------------------ 1     null         1 2     null         1 3      2           2 4      2           2 5      4           3 6      5           4 7      2           2

but getting error saying

error 35 cannot implicitly convert type 'system.collections.generic.dictionary int,anonymoustype#1' 'system.collections.generic.dictionary int,proposalsystem.handlers.main.pair'

xelement root = xelement.parse(strserializedoutput); dictionary<int, pair> list = root.descendants("item")                                  .todictionary(x => (int) x.attribute("id"),                                   x => {                             var pid = x.parent.attribute("id");                             var depthlevel = x.attribute("level");                             return pid == null ? new pair { parentid = 0, level = (int)depthlevel } :                             new pair { parentid = (int)pid, level = (int)depthlevel };                           });  public class pair {     public int parentid;     public int level; }

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
