architecture - Which is a better approach to load data from reader into objects -

-

have @ below code load list 

while (datareader.read())             {                 city city;                 if (city.tryload(datareader, out city))                 {                     defaultcities.add(city);                 }             }

tryload reads reader , loads dataobject , returns true when successful , false when unsuccessful. benefit of this, told, code not throw error if code fails reason when loading object. if 1 row of data corrupt, not added default connection. moreover, in try load can log particular row threw , error , fix that.

on other hand approach followed earlier loading objects , adding them collection. 

 while (datareader.read())                 {                     city city = new city();                     city.name = reader["name"].tostring();                     .                     .                     defaultcities.add(city)                  }

while second approach may fail due corrupt value in database, wouldn't want that? wont catching bugs due missing value become difficult in first approach?

just wanted opinion of others on pros cons of 2 approaches.

also, please in tagging question appropriately.

if can permit exception thrown on bad data, second approach best. common in situations administrators have control of quality of data.

however, it's true administrators can't guarantee quality of data. in these cases, it's requirement application handle malformed data gracefully. when faced need, first approach elegant way that.

c# - How to set Z index when using WPF DrawingContext? -

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...

visual c++ - Using relative values in array sorting ( asm ) -

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
