AutoIt is a BASIC-like scripting language for automation of Windows GUI. It uses a com- bination of simulated keystrokes, mouse movement and window/control manipulation in order to automate interactive tasks. Inside an IDE AutoIt can generate small, self-contained, and compiled executables.

In Windows Server 2008, Microsoft created a new scripting language called Power Shell for adminatration. Although Power Shell can work on XP and Vista, it is not good at GUI automation. Another GUI automation package is Perl's GUITest. In contrast to AutoIt, few developers know Perl language vs. Basic.

Samples

Now lets look at examples how to control Ladybug Mixer V4 with AutoIt. The examples look complicated at first glance, but they are simple if you know Basic language. We tried to make examples as complete as possible. So users can apply actual skills and tips in their own applications.

1. Shader Showcase

Define a function and call it in a main program

Func ShaderShowcase()

Launch "Ladybug Mixer.exe". You may modify the path in your installation path.

	Run("C:\Program Files\Neatware\Ladybug Mixer V4\host\Ladybug Mixer.exe");

Wait window with title "Ladybug Mixer V4" to become active

	WinWaitActive("Ladybug Mixer V4");

Set relative coords to the client area of the active window, the value is 2. This allows you to know the location of controls.

	Opt( "MouseCoordMode", 2 );

Move mouse to shader list in (64, 140) and set shader list as focus by clicking left button.

	MouseMove( 64, 140 );
	MouseClick( "left" );

To hide mouse cursor moving mouse out of the screen. size is an array variable with width in $size[0] and height in $size[1].

	$size = WinGetClientSize("Ladybug Mixer V4");
	MouseMove( $size[0]+32, $size[1]+32 );
