There can be a lot of windows with different names, buttons, etc. I am calling function, then it calls static _WndProc that calls non-static WndProc and creating buttons, menus, ..

I have this class with a few methods. One of them needs to compute and render something over a wide range of data (coordinates). To make the program run faster and smoother, I thought of using async methods. I created a private function that does the computation and rendering. My class: #include <future> class MyClass ..

I am using the non-blocking MPI_Isend/MPI_Irecv calls in conjunction with repeated MPI_Test calls to achieve communication/computation overlap. I have noticed that whether or not I achieve overlap depends on the frequency at which I call MPI_Test. It seems that if I call it more frequently than a certain threshold frequency, MPI_Test suddenly becomes blocking and ..

Let’s say I have an entity "Address" and an entity "User" which are linked in a 1-n-Relationship. The client sends all the necessary data which is evaluated in my controller function. The Controller Class declares the two required Mappers in the header file: (auth.h) namespace MDL = drogon_model::TestDB; public: METHOD_LIST_BEGIN ADD_METHOD_TO(Authentication::registration, "/auth/register", Post,Options); METHOD_LIST_END private: ..
