I need to create class that contains LRESULT CALLBACK WndProc. Exactly I am creating console application. Then call class-member function (createWindow) that create window using WNDCLASS. 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 C++ 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 ..

For someone who has some async experience from other languages (Python/Javascript), when talking about async/await there is always an assumption that there is an event loop somewhere. But for C++ I have looked through the documentation and have not found anywhere talking about the event loop. Why is this case? For node, it only has ..
I have written code to get data from an API. I am using an Async method to handle the call and processing of the retrieved data. The code is triggered by the user clicking a Login button on their Start page. While the Async method is running in the background, the user is redirected to ..
using experimental/filesystem and std::async is there a way to ensure filewrites finish before exiting the main thread? code used to call the async function std::vector<std::future<void>> img_Futures; for (int i = 0; i < parsedResult.size(); i++) { img_Futures.push_back(std::async(std::launch::async, downloadImage, parsedResult[i], baseFolderPath, i)); } What ends up happening is it writes most of the files, but then ..
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 ..
I have a c++ class where in one of its functions I start the following thread? std::thread([&](){ funk(); }).detach(); which runs another function of this class (func) in a thread. How can I stop or kill this thread only without killing the whole application? Source: Windows Que..
So as I said in the title GetAsyncKeyState doesnt work. In my project im doing something that detects when the left mouse button is pressed then detected when it is unpressed. Somtimesit detects the press but it mainly doesnt. Here is my code: if (GetAsyncKeyState(VK_LBUTTON) & 1) { LBdown = true; } else if (GetAsyncKeyState(VK_LBUTTON) ..
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: ..
