Usestd::mapto Store Multiple Callback Functions With Corresponding Keys in C++ A common way of using callback functions is to store them in the data structure likevectorormap, from which we can easily access each one of them and call the specific function during program run-time. In this ...
Use the std::pow Function to Calculate Powers of the Given NumberThe std::pow function is used to compute the value of the number raised to the given power. Both the base number and power value are specified as the first and the second arguments, respectively.std::pow has multiple overlo...
You can copy the code in this article to the message handler function of an event defined in an MFC .cpp file. However, the purpose of the code is to illustrate the process of using the IDispatch interfaces and member functions defined in the Excel8.olb type library. The primary benefit ...

If you’ve read my previous articles (especiallythis one) about how to use OpenCV in Unity and how to pass images between them, this post will feel like a breeze and you can just quickly skim through it. However, if you haven’t, I recommend doing so because in this post I’ll desc...
We would be writing the value function of optional and, like good library developers, we’d try to make it usable and performant in as many use-cases as we could. So we’d want value to return a const reference if the object it was called on was const, we’d want it to return ...
I have been trying to learn [the basics of] Direct2D in C++, and I came across this methodCopyFromMemorywhich seems like a perfect thing for me to use to modify individual pixels: I can modify the buffer and then call the method....
(You might need to use the locate command to find libgobject.a; many distributions now put libraries in architecture-specific subdirectories in /usr/lib.) 注意:如果要在库中搜索特定函数,请使用nm命令。准备好大量输出。例如,尝试执行此命令:nm libgobject.a(您可能需要使用locate命令来找到libgobject...

In the above code, you use defines and macros to provide a custom overload for theCompute()function. This might work, but what if you have another version of the library? With even more complex overloads. The#ifapproach might quickly become a mess of preprocessor code. What if we could...
