Dependenct Injection Intro An application is composed of many objects that collaborate with each other. Objects usually depend on other objects to perform some task. When an object is responsible for referencing its own dependencies it leads to a highly coupled, hard-to-test and hard-to-change code...

This example will demonstrate how to use Dependency Injection (DI) design pattern in Swift using these methods: Initializer Injection (the proper term is Constructor Injection, but since Swift has initializers it's called initializer injection) Property Injection Method Injection Example Set...

Let's say we have a form like the one below. We want to send the data to our webserver via AJAX and from there to a script running on an external server.

This is a lot of work, so do this as a last resort after exhausting all other options. You only need to do this if the problem is occurring for different users, on different machines. If it isn't occurring for all users, then most likely it is not a corrupt database container. Similar to the steps...

//make column H wider and set the text align to the top and right worksheet.Column(8).Width = 25; worksheet.Column(8).Style.HorizontalAlignment = ExcelHorizontalAlignment.Right; worksheet.Column(8).Style.VerticalAlignment = ExcelVerticalAlignment.Top; //wrap text in the cells worksheet.Column...

This example illustrates the basics of executing sections of code in parallel. As OpenMP is a built-in compiler feature, it works on any supported compilers without including any libraries. You may wish to include omp.h if you want to use any of the openMP API features. Sample Code std::cout <...

This example shows how to execute chunks of code in parallel std::cout << "begin "; // Start of parallel sections #pragma omp parallel sections { // Execute these sections in parallel #pragma omp section { ... do something ... std::cout <...

This example shows how to divide a loop into equal parts and execute them in parallel. // Splits element vector into element.size() / Thread Qty // and allocate that range for each thread. #pragma omp parallel for for (size_t i = 0; i < element.size(); ++i) element[i] = ... /...

This example illustrates a concept to perform reduction or gathering using std::vector and OpenMP. Supposed we have a scenario where we want multiple threads to help us generate a bunch of stuff, int is used here for simplicity and can be replaced with other data types. This is particularly useful...
