i'm still new typescript , find things find odd. take code: interface myinterface<t> { [i: string]: t; } function myfunc<t>(arg: myinterface<t>) { } var o = { 'val1': 42, 'val2': 43 }; myfunc(o); the call fails complaint "index signature missing". interestingly, it's not missing when write myfunc({ 'val1': 42, 'val2': 43 }); that mean expression { 'val1': 42, 'val2': 43 } 's type inferred backwards call (which expected), not when bound name (which weird , not how know backward inference work f#, example). but gets stranger. if change interface to interface myinterface<t> { [i: number]: t; } then corresponding var o = [42, 43]; myfunc(o); also works (in addition passing array directly). is design? rules explain this? the reason you're seeing inconsistency because you're using typescript 1.8. if try either out in typescript playground, y...

from documentation of std::unique_ptr<>() , may happen when initializing pointer not clear me. when allocating std::shared_ptr<>() , allocates memory buffer handle reference counter. may std::bad_alloc exception. could similar happen when initializing unique pointer? i asking question because if does, may lose attempting have delete through unique pointer. example: void deleter(file * f) { fclose(f); } void func() { ... file * f(fopen("/tmp/random", o_creat | ...)); if(f == nullptr) ...handle error... std::unique_ptr<file, decltype(&deleter)> raii_file(f, deleter); ... } so, if initialization of unique_ptr<>() can throw, may end keeping file f open forever.

we can update cursor position of uitextfield this. [textfield setselectedrange:beginningrange]; is possible update cursor position keyboard extension? checking textdocumentproxy , inputview though. simply set length of selection zero. one possible implementation: + (void)setcursorintextfield:(uitextfield *)textfield atindex:(nsinteger)index { uitextposition *start = [textfield positionfromposition:[textfield beginningofdocument] offset:index]; uitextposition *end = [textfield positionfromposition:start offset:0]; [textfield setselectedtextrange:[textfield textrangefromposition:start toposition:end]]; }

having known nothing interfaces until now, having remarkably hard time trying implement solution given this question . i think correctly getting pointer ishellfolder interface, don't seem able use pointer. how usable interface when having pointer? the code below shows doing , suspect problems. first, interface delarations : ' have wrapped interfaces in own namespace, "binarusshell". ' have declared every interface's functions / subs in same order in .idl files of windows platform sdk 7.1. ' every function / sub has <preservesig()> attribute can see native return values when debugging. ' i'd keep question lean possible, showing few functions per interface. ' of course, have implemented of them (as in respective .idl file). namespace binarusshell <comimport()> _ <interfacetype(cominterfacetype.interfaceisiunknown)> _ <guid("000214fa-0000-0000-c000-000000000046")> _ public interface iextracti...
