Udf Question

[Dx3]

Hello everyone, I'm new here (first post ). I have a question, what are UDF's? How do I use them, do I need to add something extra to use them? Thanks, bye.

User defined functions.

You can #include a file containing UDF's at the begining of the script.

#include 'Someones_udfs.au3'

_UDF('Welcome Dx3')

Func _UDF($text)
    MsgBox(0, '', $text)
EndFunc

User Functions

User functions are declared using the Func...EndFunc statements.

Functions can accept parameters and return values as required.

Function names must start with either a letter or an underscore, and the remainder of the name can contain any combination of letters and numbers and underscores. Some valid function names are:

MyFunc

Func1

_My_Func1

Here is an example of using a function to double a number 5 times:

$val = 10

For $i = 1 To 10

$doubled = MyDouble($val)

MsgBox(0, "", $val & " doubled is " & $doubled)

$val = $doubled

Next

Exit

Func MyDouble($value)

$value = $value * 2

Return $value

EndFunc
