How to hijack an event handler?

In event driven programming,how do you create an event handler?

• How do you create an event handler for events that are not keystroke or mouse click or a scan? Which programming language is better to handle this? If i were to develop in C++/C# , how do I start?

• Answer:

  An event is a function with a predefined trigger, like a mouse click or text field modification. Without the trigger, it is just a regular function that your program would call depending on whatever criteria you as the programmer specify. if I write a function that counts 2 numbers called count, then I would use it as x = count(1, 2). If I then bound this function to a button it would be an event function that would occur when the button is pressed, but its the exact same thing, and this is true in any language that you work in.
