c# - read XML, save it into dictionary with multiple values -


ok have following 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>

i dictionary output this, way can insert data sql database,

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

currrently code first 2 columns, not sure how 3rd column "level" show in dictionary.

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

really, use use datatable, buuut potentially use anonymous type well:

xelement root = xelement.parse(strserializedoutput); var list = root.descendants("item")     .todictionary(x => (int)x.attribute("id"), x =>     {         var parentid = (int)x.parent.attribute("id");         var level = (int)x.parent.attribute("level");          return new { parentid = parentid, level = level };     });

so example, when write db, you'd use list.parentid , list.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...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
