i little bit confused of states , animations in wpf. i make usercontrol. usercontrol contains (inside main grid) 2 grid. 1 of them header , second 1 content. if user click on header, content expand, otherwise collapsed. , animation expanding (slide down content header). basicaly states (for future purpose). problem is, if add states , using slide efect transformation, content of grid (content grid) transformed well. use states modifying height of element. if u modify element, no animation appear , change height @ once. the hierarchy looks like: --- wrapper grid ------ header grid --------- content of header ------ content grid --------- content of content grid (like buttons, labels, etc) the visualstates looks like: <visualstatemanager.visualstategroups> <visualstategroup x:name="visualstategroup"> <visualstategroup.transitions> <visualtransition generatedduration="0:0:1"/>

i got anaconda python , using spyder ide. i'm trying figure out how can use relative import run bottom or f5. suppose have pkg/a/foo1.py, pkg/a/foo2/py, , foo1.py has "from . import foo2", if hit run report relative import error. i know how in command line environment can type, e.g. "python -m pkg.a.foo1". how can in spyder ide? thanks jq if there pkg/a/__init__.py file i.e., if pkg.a python package from . import foo2 correct. doesn't matter write code in spyder ide, notepad, or emacs; code same. the remaining question how run python scripts in spyder ide. don’t directly run modules inside packages i.e., don't run python pkg/a/foo1.py . leads python modules being available under different names. see traps unwary . run python -m pkg.a.foo1 project directory instead. configure command run on f5 if spyder ide allows it.

in oracle documentation, repeatedly mentioned preferable users of application database users instead of records in kind of 'user' table numerous reasons. example, @ docs.oracle.com/cd/b28359_01/network.111/b28531/… -- "where possible, should build applications in application users database users. in way, can leverage intrinsic security mechanisms of database." i reasonably familiar call 1 big application user pattern, have been suitably convinced not best way. however, seems creating database user every web user not particularly possible either, question is, best practices keeping security definition of data separate application accesses it? some ideas: a secure interface in between database , application. application never knows database. create views utilize application context automatically filter out rows application user cannot read, , grant application user access view. similarly create procedures utilize application context allow authorized data ac

i'm studying collections right , learned saw set type of collection don't permit duplicate elements. ok, i've created class adds 3 int numbers collection. seems ok question is: how print collection? know override string method since elements integer type how that? expected output be: 2,3,2 4,5,6 the code (adding numbers) public class adaugarenumere { int c=0; int f=0; int r=0; adaugarenumere(int c, int f, int r){ this.c=c; this.f=f; this.r=r; } } main class: import java.util.*; public class executare { public static void main(string[] args) { adaugarenumere primulrand=new adaugarenumere(2,3,2); adaugarenumere aldoilearand=new adaugarenumere(2,3,2); adaugarenumere altreilearand=new adaugarenumere(4,5,6); set<adaugarenumere> lista=new hashset<adaugarenumere>(); lista.add(primulrand); lista.add(aldoilearand); lista.add(altreilearand); system.out.println("elementele listei: "+arrays.aslist(lista.tostring())

the next c# version planned ( april 2014 ) have binary literals can see in language features status of roslyn project . the example in page this: 0b00000100 so use this: var mybynaryliteral = 0b00000100; i want understand why choose prefix 0b instead of use letter in end did double , float , decimal , on. double = 1d; float b = 1f; decimal c = 1m; integer literals possess 2 varying properties: types, can specified suffixes l or ul , , radices (called "forms" in documentation ), can specified prefixes 0x , 0b . specifying type done through suffix, , specifying radix done through prefix, makes sense keep same convention. in addition, can combine both specifiers. for instance: 0b00101010ul would denote literal 42 , stored unsigned long, , expressed in radix 2.

i have code , when executes, throws nullreferenceexception , saying: object reference not set instance of object. what mean, , can fix error? what cause? bottom line you trying use null (or nothing in vb.net). means either set null , or never set @ all. like else, null gets passed around. if null in method "a", method "b" passed null to method "a". the rest of article goes more detail , shows mistakes many programmers make can lead nullreferenceexception . more specifically the runtime throwing nullreferenceexception always means same thing: trying use reference, , reference not initialized (or once initialized, no longer initialized). this means reference null , , cannot access members (such methods) through null reference. simplest case: string foo = null; foo.toupper(); this throw nullreferenceexception @ second line because can't call instance method toupper() on string reference pointing null .
