This post will discuss how to use `std::pair` as a key to `std::map` in C++. The `std::pair` in C++ binds together a pair of values of the same or different types, which can then be accessed through its first and second public members.
(FILE_MAP_WRITE, // Read/write access. FALSE, // Do not inherit the name. sectionName); } static HANDLE OpenEvent(LPCWSTR eventName) { return ::OpenEvent (EVENT_MODIFY_STATE | SYNCHRONIZE, FALSE, eventName); } static CString GetEventName(LPCWSTR sectionName) { CString cs = L""; ...
The Java bitmap image or the JavaBufferedImagehas several different types. You can set the flag variable representing the type of the image in the constructor itself. The types differ in the coloring schemes, and you can even produce a grayscale picture. To know more about the flags and me...
We will introduce how to convert an existing JSON to a Map in Java. JSON is often used to structure the data, but sometimes we have to get the JSON values into some other data type and then work on it. Several libraries are created to work with JSON in Java. We will see the two ...
Comparing to the Java code of the desktop application, the only difference is the way of operating image bytes on Android. In Android SDK, there is no class namedBufferedImage. Instead, we should useBitmap. Generating QR Code to ImageView on Android ...

The next sample shows how to access types outside the assembly. In this sample, the client consumes the component that's built in the previous sample. C++ // type_visibility_3.cpp// compile with: /clr#using"type_visibility_2.dll"intmain(){ Public_Class ^ a = gcnew Public_Class; a-...

Get Multiple Keys From Value Using the Stream API in Java Hashmap is an essential part of Java and gives us the power of flexibly work on our data by using the key-value pair method. The value is attached to the key, and we can find the value using its key very easily. But what ...
