Showing the desktop via IShellDispatch4

7 posts in this topic

Hi guys,

A webpage gives some C# to toggle the desktop (equivalent to hitting Win+D):

// Create an instance of the shell class
Shell32.ShellClass objShel = new Shell32.ShellClass();

// Show the desktop
((Shell32.IShellDispatch4) objShel).ToggleDesktop();

// Do some operations here

// Restore the desktop
((Shell32.IShellDispatch4) objShel).ToggleDesktop();

I've spent an hour or so trying to convert this to its AutoIt equivalent. It obviously has something to do with ObjCreate() but everything I've tried so far has given me an @Error code of -2147221005 (odd)...

Local $Obj = ObjCreate("IShellDispatch4")
Local $Obj = ObjCreate("IShellDispatch4.This")
Local $Obj = ObjCreate("Shell.IShellDispatch4")
Local $Obj = ObjCreate("Shell32.IDispatch4")
Local $Obj = ObjCreate("Shell32.IID_IShellDispatch4")

Some other pieces of code floating around refer to this object by its CLSID but I'm not sure whether that can be done using AutoIt. I tried all sorts of things there too:

Local $Obj = ObjCreate("13709620-C279-11CE-A49E-444553540000")
Local $Obj = ObjCreate("{13709620-C279-11CE-A49E-444553540000}")
Local $Obj = ObjCreate("CLSID::13709620-C279-11CE-A49E-444553540000")
Local $Obj = ObjCreate("CLSID::{13709620-C279-11CE-A49E-444553540000}")

How might the above C# code be written for AutoIt?

Try this:

$oShell = ObjCreate("Shell.Application")
$oShell.ToggleDesktop()

So simple -- I was way off. Thanks Dale!

For next time, how did you come up with Shell.Application from IShellDispatch4? I couldn't see anything obvious on MSDN saying that IShellDispatch objects extend Shell objects...

P.S. Thanks anyway Valuater!

You want me to reveal my tricks huh? I was hoping you wouldn't ask ;)

I took a quick look in MSDN for an example of instantiating the IShellDispatch4 object... when I couldn't find one I thought, hmmm, I wonder if this will work... and it did...
