How to use optional parameters in AutoHotkey Functions

optional parameters in AutoHotkey FunctionsFunctions in AutoHotkey rock!  Some functions though have items that either 99% of the time are the same value or are things that you rarely use.  In this case using optional parameters in AutoHotkey Functions is a great way to simplify your code!  Just remember that the optional parameters have to be listed after all of the required parameters.

In the below video I demonstrate how to set defaults and pass optional params to an AutoHotkey function.

Use ByRef to Return Multiple Values from AutoHotkey Functions via

Return Multiple Values from AutoHotkey FunctionsIn my initial video I talked through how & why to use AutoHotkey functions as well as how to return one value from a function.  This video will demonstrate how to Return Multiple Values from AutoHotkey Functions via the byRef command.  You can also return multiple values by returning an Object or an Array which can hold any-number of values..  The byRef command can seem a bit tricky at first, but it really is an easy way to return many values from a function. My next video will cover using the Include command

Intro tutorial on using AutoHotkey functions to streamline code

AutoHotkey functionAutoHotkey functions are a true gem that help streamline your code, make it more readable, easier to maintain, and avoid conflicts with other variables (because their scope is local by default.  They take a little practice getting used to however they can save a ton of time and allow for re-using a ton of code.   Don’t get hung-up on writing them at the beginning of your script.  Often I go back after writing my script and realize I should have written a function in place of a subroutine.

My first video on AutoHotkey functions explains why & how you can use them.
