if have xml schema dictates element has default value, , have xml file following schema omits element still valid? i.e. if element missing validator ok element missing take default value defined in schema , xml valid? so maybe like: <xs:element name="test" type="xs:boolean" default="false"/> then xml file misses out 'example' element together, valid? the reason ask because i've seen many schemas elements using attribute: minoccurs="0" infers if elements missing still validate. question validate if minoccurs not specified there default value specified instead? thanks. minoccurs , default refer 2 different concepts. question needs more context answered completely. minoccurs refers number of times element can occur child of another. default refers string value (sometimes typed - e.g. here boolean). use of default on element invalid . here default attributes (from w3schools) default attribute...

i have qt4 application svg icons, compiled mingw (in windows), linked qt shared libraries. when application run, svg icons show in debug , release builds in linux, in windows svg icons show in debug build not in release build. all svg icons listed in project.qrc , , project.pro has resources = project.qrc . application uses qtsvg4.dll (version 4.7.0). qt 4.7.0, qt creator 2.0.1, mingw/g++ 4.4.0. solution update: in application directory, create /imageformats/ directory , put qsvg4.dll there instead of application directory itself, or create qt.conf file appropriate path. more information in deploying plugins . most have include plugins qt dir. involves making qt.conf file local app (see here: http://doc.qt.io/qt-4.8/qt-conf.html , more [paths] section), , copy c:\qt\4.x.x\plugins\imageformats*.dll distributable's directory.

i hope can explane me how this: i have tabbar , 2 tabbaritems, how can attatch items tabbar. not doing via ib because tabbar fits have of screen because items should on left side. thats how build them: tabbarcontroller = [[uitabbarcontroller alloc] initwithnibname:nil bundle:nil]; tabbarcontroller2 = [[uitabbarcontroller alloc] initwithnibname:nil bundle:nil]; tabbarcontroller.tabbar.frame = cgrectmake(0, 974, 384, 50); tabbarcontroller2.tabbar.frame = cgrectmake(384, 974, 384, 50); uitabbaritem *tbi1 = [[uitabbaritem alloc] initwithtabbarsystemitem:uitabbarsystemitemmostviewed tag:0]; uitabbaritem *tbi2 = [[uitabbaritem alloc] initwithtabbarsystemitem:uitabbarsystemitemmostviewed tag:1]; you don't set tab bar items directly in tab bar. instead, assign tab bar item tabbaritem property each view controller contained tab bar controller. when add view controllers tab bar controller, tab bar controller manage display of tab bar items you. uitabbarcontrolle...

my application creates window purpose of handling wm_devicechange windows message. wndproc called several times, until application calls function poll keyboard events, whatever reason not called when remove or insert usb device. this guid usb device. i'm sure it's correct: static const guid _guidforcp210xdevices = { 0xa2a39220, 0x39f4, 0x4b88, 0xae, 0xcb, 0x3d, 0x86, 0xa3, 0x5d, 0xc7, 0x48 }; this how window created: m_hinstance = ::getmodulehandle( null ); if ( m_hinstance == null ) { trace(_t("cnotifywindow::cnotifywindow : failed retrieve module handle.\r\n\terror: %d\r\n\tfile: %s\r\n\tline: %d\r\n"), ::getlasterror(), __wfile__, __line__); throw(::getlasterror()); } m_wcx.cbsize = sizeof(wndclassex); // size of structure m_wcx.style = cs_hredraw | cs_vredraw; // minimized m_wcx.lpfnwndproc = &wndproc; // points window procedure m_wcx.cbclsextra = 0; // no class memory m_wcx.cbwndextra = 0; // no...

assuming have regex: preg_match('/\b(xbox|xbox360|360|pc|ps3|wii)\b/i' , $string, $matches); now, whenever regex match ex. one of 3 xbox methods (xbox|xbox360|360) , $matches , should return xbox is possible continuing work in preg_match() context or should use other method? thank's in advance. edited: im doing this: $x = array('xbox360','xbox','360'); if( preg_match('/\b(xbox360|xbox|360|pc|ps3)\b/i', $s, $m ) ) { $t = $m[0]; } if ( in_array($t,$x) ) { $t = 'xbox'; } i'm wondering if there way! your current code looks ok me, if want bit fancier, can try named subpatterns preg_match('/\b((?p<xbox>xbox|xbox360|360)|pc|ps3|wii)\b/i' , $string, $matches); $t = isset($matches['xbox']) ? 'xbox' : $matches[0]; or preg_replac'ing things before matching: $string = preg_replace('~\b(xbox|xbox360|360)\b~', 'xbox', $string); preg_match('/\b(xbox|pc|...

intellisense has stopped working aspx files, , i've looked @ other questions address issue no solution. when try format aspx document (ctrl-k, ctrl-d) status bar says "the key combination bound command (format document) not available." the outlining no longer showing up. i have tried /resetsettings flag. i'm not using resharper. i've verified settings (tools -> options, text editor) both c#, basic, , html general. how can back? i managed fix switching design mode , clicking on source. strangely, had right-click select design view, since design/split/source options @ bottom of window not present. once switched design view, buttons came back, , when switched source view seems work again. strange.

i have .net windows app. i have datagridview has few rows in it. had added column containing buttons allow user edit row. pops new form/dialog - edit form. // add cellclick handler handle clicks in button column. dgv.cellclick += new datagridviewcelleventhandler(dgv_cellclick); the code fires is: private void dgv_cellclick(object sender, datagridviewcelleventargs e) { if (e.columnindex == buttoncell) { // id number int number = convert.toint32(dgv.rows[e.rowindex].cells[0].value); editform edit = new editform(number); edit.showdialog(); } } problem my edit form displays (correctly). make changes, , close form. loads again! same number of rows in grid. ie. fires code above once each row in datagrid. how can prevent this? there more elegant solution? i make sure you're not registering cellclick event more once. i.e., you're not calling code more once (like each time add row dgv): ...

suppose have makefile: all: $(binary) $(binary): $(objs) $(debug_objs) #link objects here $(objs): headers #compile code objects without debug option $(debug_objs): headers #compile code objects debug option headers: #create on-the-fly header files as can see, target headers required both $(objs) , $(debug_objs) . question is, headers called twice? also, below code equal/equivalent above: all: $(binary) $(binary): headers $(objs) $(debug_objs) #link objects here $(objs): #compile code objects without debug option $(debug_objs): #compile code objects debug option headers: #create on-the-fly header files in that, headers called before $(objs) , $(debug_objs) $(binary) ? no, headers done once. you can write simple makefile test it: all: foo bar foo: baz bar: baz baz: echo 'hi' on doing make , hi echoed once. and in 2nd case make sees $(binary) depends on headers first, goes , headers before...

what open source, well-documented audio (video not required) streaming (from server) protocol supports recording (to server), should use new application? rtmp not option this protocol must have client library ac3/ac2 thanks. why not use shoutcast ? sounds work perfect application. as far recording stream goes, can use streamripper , or wget. no special client library necessary, compatible http. thing have worry client keeping audio buffer around after has been played, there many solutions that, as3.

i have class can called either gui or form non-graphical environment (batch mode) what convenient best practice way "tell" gui-related parts of code not execute when executed in batch mode. i think of like public mymethod() { [@tag: dothis_only_if_guimode] showpanels(); .... } and gui_mode_activated set true or false on runtime somewhere, depending on program called from i want avoid ugly tracing if/else stuff scattered on code. little thumb tells me aop way go (but if manage find simpler alternative i'll go it) so, simplest , straightforward way ? update: as contributors pointed out, separating gui code business code rule of thumb, still interested in knowing ways if no gui involved (ie, 2 different batch modes 2 different environments, example) i think best bet take gui-specific code out of class , implement events triggered @ key times in class's processing. when called gui, gui code subs...
