database - Data model for a C# winform application -

-

i'm writing winform program following data model:

  • the data structure described set of class , subclass
  • once store data, i'm serializing class xml file.

when software running data must accessed fast (the data model accessed between 50 , 60 per second.

i plan move data storage xml file lite database.

my question following: realistic use database not storage, during program execution? face loss of performance?

if don't need update data regularly, read it, best keep in memory.

we know little app, cannot give better advice here. maybe in case enough keep xml in xpathdocument structure, can perform fast searches using xpath queries.

another option be, if data key/value pairs, read xml dictionary , search dictionary in app.

but reading database, light one, hardly faster. counter-case can think of read-optimized fast nosql-db such mongodb. money on in-memory data structure optimized searching.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
