structure

问题 short version: Suppose a structure B.(SomeFields).field1 with SomeFields being a bunch of fieldnames of any possible length: e.g. SomeFields = 'toplevel.middlevel'or SomeFields = 'toplevel.middlevel.bottomlevel'. The former syntax does not actually work in Matlab, in only works with 1 level op depth, so one fieldname. How can I assign a new field to B.(SomeFields) when SomeFields refers to e.g. 3 levels op depth? To get an existing field, I use getfield(B,SomeFields{:}) with fields being a

问题 I am working on an emulation tool in windows. On intercepting an application I landed up with a situation. I have a c++ structure which has the following format typedef struct node { int open; int version; const unsigned long long * data; char* flags; } _node; It is a handle to a binary file. I am doing API interception and I get this pointer from an internal API call being made by the application. Also The data field in the structure above is a pointer to instances of two structures laid out

问题 I have a ploblem about circular template reference. I want to make a tree using class node and class edge as following; template <typename EdgeT> class node { public: std::vector<EdgeT> edge_out; std::vector<EdgeT> edge_in; }; template <typename NodeT> class edge { public: NodeT* src; NodeT* dst; int weight; }; template <typename NodeT, typename EdgeT> class graph { public: std::vector<NodeT> nodes; }; I found that I cannot declare graph class ex: graph< node, edge > g; // <--- this cannot be

问题 I am creating an array as below: public struct Smb_Parameters { public byte WordCount; public ushort[] Words; } While I assign the values Like below: Smb_Parameters smbParameter = new Smb_Parameters(); smbParameter.WordCount = 0; string words= "NT LM 0.12"; smbParameter.Words = Encoding.ASCII.GetBytes(name); In the above assignment smbParameter.WordCount contains the value 0 but does smbParameter.Words contains directly the values(Arry of byteS) or memory reference to the location that

问题 My understanding is that MySQL is intended to have tables with millions of rows. I am looking for a database system designed to have millions of relational tables. Am I correct in my understanding that the way MySql queries data makes it inefficient for that sort of an implementation? It is for a long-term, user-driven project, so extensibility is a must. Thanks! EDIT: Due to the immediately negative reaction, I'll explain myself. "Millions" of tables would be an issue if the project lived to
