does c++ standard guarantee (either explicitly stating or implicitly logical deduction) std::uintmax_t can hold values of std::size_t ? or possible std::numeric_limits<std::size_t>::max() larger std::numeric_limits<std::uintmax_t>::max() ? yes. size_t defined unsigned integer type large enough contain size of object. uintmax_t defined able store value of unsigned integer type. if size_t can store it, uintmax_t can store it. definition of size_t c++11 §18.2: the type size_t implementation-defined unsigned integer type large enough contain size in bytes of object. definition of uintmax_t c99 §7.18.1.5 (it included in c++ normative reference): the following type designates unsigned integer type capable of representing value of unsigned integer type: uintmax_t

help me out here, because i'm half convinced can't want , half convinced there should suitable workaround. i have dll that's implemented in c++ , exports classes other c++ modules link it. that's fine. want link dll c module (another dll), provide "flattened" c interface , handle c++ stuff internally. that's fine. the problem want supply c or c++ clients single .h , associated .lib. have similar following in dll: #ifdef dll_exports #define dll_api __declspec(dllexport) #else #define dll_api __declspec(dllimport) #endif // export class c++ clients class dll_api cexportedclass { public: cexportedclass(); // etc. etc. }; // export flattened c interface non-c++ clients #ifdef __cplusplus extern "c" { #endif dll_api void dosomethinginternally(); // i.e. implementation uses cexportedclass #ifdef __cplusplus } #endif of course, works fine when imported c++ module, fails compile when imported c module because doesn't recogni...

i want create expandable uiscrollview images shown above. i've tried search keywords cannot find example similar want achieve. i wonder if should use uiscrollview or uitableview ? any advice appreciated. thank in advance. you can create uitableview rotate 90 degrees counter clock wise , work charm. just create uitableview subclass (i.r. horizontaluitableview) , in initwithframe, rotate view 90 degrees: - (id)initwithframe:(cgrect)frame { self = [super initwithframe:frame]; if (self) { // initialization code self.transform = cgaffinetransformmakerotation(-m_pi/2.0); self.showsverticalscrollindicator = no; } return self; } you need subclass uitableviewcell's , rotate them 90 degrees too

what i'm trying following: 1) have following wcf service contract: [servicecontract] public interface iuploadservice { [operationcontract] servicedata upload(request request); } [datacontract] public class request { [datamember] public long abnnumber; [datamember] public string email; } 2) contract implemented this. public class uploadservice : iuploadservice { public bool upload(request request) { // code } } in "some code" section call validation class validate clients request, this: var result = validation.validaterequest(request); so question is: bad idea create instance of validation class inside upload method? this: public class uploadservice : iuploadservice { public bool upload(request request) { var validation = new validation(); var result = validation.validaterequest(request); } } i know can around creating constructor far know can't create constructor inside wcf ...

i have 3 table shop, item , item_type the shop contains names of shops , item contains items of each shop , item_type contains different types of items along status such available or not available. now want render format.json { render json: {:shop => @shops.as_json(:include => :items)}} but based on condition, items item_type_id='1' , status of item_type_status='available' try this: @shops = shop.includes(:items).where("items.itemp_type = ?", 'accesories') format.json { render json: { :shop => @shops.as_json(:include => :items) } } edited: one way create hash objects want render, , pass render method. so: respond_to |format| format.json { render :json => {:shops => @shops, :items => @items }} end if models aren't associated through active record, that's best solution. if association exist, can pass :include argument render call, so: respond_to |format|...

i building tracking platform has following use cases. need track 50,000 vehicles each vehicle relays location every 60 secs. get api returns vehicles in x km range. so, need scale writes , achieve query isolation. can create shard cluster geographical region shard key(geohash). me balance writes , achieve query isolation. happens when vehicle moves across regions mangodb automatically move document new shard in case? you cannot change shard key fields record once written. using region shard key prevent moving across regions unless delete record in original region , insert using new one. on choosing shard key, 1 matches common query pattern. querying on shard key allow retrieve record directly shard. queries don't use shard key have perform scatter gather query against shards. if on or can use mongodb 2.4, , don't need perform range based queries, may want consider using hashed shard key allow distribution, if shard key monotonically increasing. see th...
