What is the binary representation of a boolean value in c# -

-

i know boolean value 1 byte (8 bits long) know binary representation. e.g. decimal => binary 4 => 100 (0000 0100) 8 => 1000 (0000 1000) bool value => ???

bool built-in basic type in c#. underlying representation implementation detail.

the c# 4.0 language specification states in section 4.1.8:

the bool type represents boolean logical quantities. possible values of type bool true , false.

no standard conversions exist between bool , other types. in particular, bool type distinct , separate integral types, , bool value cannot used in place of integral value, , vice versa.

in c , c++ languages, 0 integral or floating-point value, or null pointer can converted boolean value false, , non-zero integral or floating-point value, or non-null pointer can converted boolean value true. in c#, such conversions accomplished explicitly comparing integral or floating-point value zero, or explicitly comparing object reference null.

if take 1 level deeper , see how corresponding type specied in common intermediate language (cil) see cli boolean type occupies 1 byte in memory. common language infrastructure (cli) specification says in partition iii, section 1.1.2:

a cli boolean type occupies 1 byte in memory. bit pattern of zeroes denotes value of false. bit pattern 1 or more bits set (analogous non-zero integer) denotes value of true.

however, specified on level , within c# should not have care; if future version of cli specification might change representation of boolean type, or if c# compiler decided map bool in c# different, c# code still have same semantics.

windows - Why does Vista not allow creation of shortcuts to "Programs" on a NonAdmin account? Not supposed to install apps from NonAdmin account? -

i'm working on installer (using wise installer, older version 1999). i'm creating shortcut in programs group exe. i'm creating shortcut on desktop. if install run admin account, create shortcut on common desktop , common program group (i.e., read hkey_local_machine\explorer\shellfor users). if it's installed nonadmin account, install hkey_current_user's desktop , program group. behavior install on: xp nonadmin - desktop , program shortcuts install ok. vista admin - desktop & program shortcuts install ok. vista non-admin, uac off - desktop shortcut installs, program shortcut not . however, program group folder they're supposed installed does created. at end of install, launch program group has shorcut. launches in of above. can manually drag shortcut folder , works fine. i'm bloody baffled. i've tried installing other commercial apps (opera, foxit, firefox) firefox install under nonadmin (and if select other program files,...

c++ - How do I get a multi line tooltip in MFC -

right now, have tool tip pops when hover on edit box. problem tool tip contains multiple error messages , in 1 long line. need have each error message on own line. error messages contained in cstring new line seperating them. my existing code below. bool ontooltiptext(uint, nmhdr* pnmhdr, lresult* presult) { assert(pnmhdr->code == ttn_needtexta || pnmhdr->code == ttn_needtextw); // need handle both ansi , unicode versions of message tooltiptexta* pttta = (tooltiptexta*)pnmhdr; tooltiptextw* ptttw = (tooltiptextw*)pnmhdr; // tchar szfulltext[256]; cstring strtiptext=_t(""); uint nid = pnmhdr->idfrom; if (pnmhdr->code == ttn_needtexta && (pttta->uflags & ttf_idishwnd) || pnmhdr->code == ttn_needtextw && (ptttw->uflags & ttf_idishwnd)) { // idfrom hwnd of tool nid = ::getdlgctrlid((hwnd)nid); } //m_errprojaccel[ch] contains 1 or more error messages each...

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
