while reading on working directory , script directory (or directory contains image of executable file) directories are, started wondering, how windows know, directory pass process working directory, when don't specify working directory when launch given program: through command line, pass location of script directory (~as zeroth parameter). note script directory not working directory. i know can use getcurrentdir() retrieve working directory inside of program, i'm wondering, windows have 'internal' structure stores working directory of given process? (and if yes, there documentation on structure). i've found out following process related structures, appears none of them contains working directory property. process_information peb peb_ldr_data rtl_user_process_parameters the shell (or program launches script), calls createprocess() function. createprocess function has lpcurrentdirectory parameter. shell (or other program launches sc

when adding projects tfs, i'll add project specific website. works fine, , folders , files within root of website available in tfs. however, there shared files above root of website, , not included in specific website project/solution, since reside outside root of website. example, when add existing files project, outside root, creates duplicates within project. or, when adding existing file project, creates wrong folder hierarchy in project (appears though folder above root inside website), result in problems publishing , sharing source in tfs. what appropriate way include these files in project, files can remain outside root, included in project in tfs. one way might achieve having one team project websites , , logically break different sites backlogs/iterations/work items etc using teams/areas. source code within correct hierarchical structure within 1 team project, , can shared between subprojects within team project. see following posts discussion of ap

i have data set, (call data) variable, color. mode of color numeric , class factor. first, i'm bit confused "numeric" -- when printed out, data color not numeric -- character values, white or blue or black, etc. clarification on appreciated. further, need write r code return levels of color variable, determine current reference level of variable, , set reference level of variable white. tried using factor, entirely unsuccessful. thank taking time help. mode(data$color) "numeric" because r internally stores factors numeric codes (to save space), plus associated vector of labels corresponding code values. when print factor, r automatically substitutes corresponding label each code. f <- factor(c("orange","banana","apple")) ## [1] orange banana apple ## levels: apple banana orange str(f) ## factor w/ 3 levels "apple","banana",..: 3 2 1 c(f) ## strip attributes numeric vector ## [1] 3 2 1

can provide me simple example showing creation of uilabel has both bold , plain text in single label? i have searched around , managed piece dramatically modifies uilabel's look, can't figure out how change parts of label... surely can't difficult? imagine need create uilabel, use nsattributedstring text, , specify nsrange parts of want bold? to clarify, using monotouch. something this, although you'll need use more complicated set of attributes nsattributedstring label.attributedtext = new nsattributedstring ( "label", underlinestyle: nsunderlinestyle.single);

this question duplicate of question here: returning anonymous types stored procedure linq2sql but been 4 years , no 1 has answered it, hoping like..bump up. need answered, been struggling same issue. thanks you can generate xml-like string in store procedure , use xmlserializer deserialize more complex object in runtime. use attribute in xml can distinguish between different types of objects returning value referring to. edit: 1 other workaround returning varbinary object stored procedure include binary data needed instantiate desired object. of course using method, difficult maintain code.

in class hierarchy where: mnglayers extends manager_panel , extends manager_base ... -- in manager_base , i've defined init() method: public class manager_base { //.... public function init():void { //do initialization here... } } -- in manager_panel , not override init() method. -- in mnglayers , override init() method. public override function init():void { super.init(); //do custom initialization here... } when attempt compile this, unhelpful compilation error: error: conflict exists definition init in namespace public. i'm not sure matters, i'm using asc2.0 compiler (from air sdk 3.7) -inline support. is there broken in compiler prevents doing simple method-overriding compilation previous compiler could? ah! damn, it's asc2.0 not being descriptive enough! my bad, had duplicate init() overriden method in leaf sub-class (mnglayers) time. of helped if compiler pointed out duplicate 1 instead!

summary : happens if declare struct , class same name. details : i'm reviewing code , saw warning this: warning: struct 'foo' declared class when compiling clang there couple of places clang added notes saying: foo.h:29:1: note: did mean struct here? class foo; ^~~~~ struct obviously not coding practice have struct , class same name. looks happened developer writing own class , used name in use in file including , did not notice that. however, question compiler able tell difference between variables declared class foo , ones struct foo ? edit : actually happening developer using class foo in class bar had created. think in meantime place class foo declared had been changed struct bar . why code compiling. guess answer question struct , class interchangeable when declaring objects. still guess it's idea use them consistently. the keywords struct , class largely interchangeable. if write struct foo , have created class type n

i'm using django endles-pagination load pages in infinite scroll. have filters filter data according criteria (for eg, price slider filtering according price). when page loads, filter right filters page loaded, though want filter pages have been or loaded. there way (by making ajax request or something)? any on great. lot. to filter data have redefine get_queryset() method in views requesting filtered query. for example request current language in template filter blog posts based on language: class blog(ajaxlistview): context_object_name = "posts" template_name = 'cgapp/blog.html' page_template = 'cgapp/post_list.html' def get_queryset(self): if self.request.language_code == 'en': #request value of current language return news.objects.filter(language='en') #return filtered object if current language english else: return news.objects.filter(language='uk') to filter queryset b
