I'll demonstrate the basic usage of using functions vs using labels+gosub. In this example we'll implement simple functionality to add two numbers and store them in a variable. With functions: c := Add(3, 2) ; function call MsgBox, Result: %c% Add(a, b) { ; This is a function. Put it wherever...

This script demonstrates how to receive complicated GUI events from different controls in the same event callback function. We'll be using two ListView controls for that. Now every time an action is detected on one of those ListView controls, we want a precise description of what happened and have ...

Here is a very simple example to illustrate how to write a NIF. Directory structure: nif_test ├── c_src │   ├── Makefile │   └── nif_test.c ├── rebar.config └── src ├── nif_test.app.src └── nif_test.erl This structure can be easily initialized using Rebar3: $ rebar3 new lib nif_...

Here is an example of an IntentService that pretends to load images in the background. All you need to do to implement an IntentService is to provide a constructor that calls the super(String) constructor, and you need to implement the onHandleIntent(Intent) method. public class ImageLoaderIntentSe...
