You say "The shell receives HSHELL_GETMINRECT ( with a shellhook structure ) whenever a window is being Minimised/Maximised. A script may monitor it to Minimize a window to the tray."

I was using Window 98 while I was experimenting.. and then I shifted My OS to 2k and currently using XP.
I can safely say HSHELL_GETMINRECT is very unpredictable in different OSes.
( If it works at all and ) If you are to use it only on your system, you are lucky. Otherwise, I do not recommend SHELLHOOK to monitor Maximize/Minimize events.

Does anybody have problems with Shell hook and activation ?

I don't receive notifications on Vista. For instance, here is the output of SKANs utuility where different windows were activated:

Activation definitely doesn't work correctly. The same code works on XP and doesn't work on VISTA, and sometimes it even stops working in XP.

[zhuluobin]

i used shellhook code but while i right clicked 'my computer' on start menu to open 'system properties' i received nothing.

Does anybody have problems with Shell hook and activation ?

Yes here!

I'm glad its not just me thats having shell notification problems.
I thought I wasnt feeding the proper hWnd or something.

In some cases even normal Windows Messages are not detected with OnMessage.
I think there has to be a more robust method for using a given handle :? ..

here is the output of SKANs utuility

Where to find it plz?
Oh, its Shell Spy.. Got it

Ok so it looks like the hook method only works on toplevel windows.

There must be a way to hook all window and even control handles!

SHELLHOOK works only on toplevel windows. The OS messages the Shell whenever a window is created/destroyed so that taskbar can update its buttons.
For windows which do not have a taskbar button, the messages will not be sent, which makes sense.

With SHELLHOOK method, we merely intercept the messages without much load on the system resources.

Try WinEventHook Messages by Serenity

Explained that way, it absolutly does make sense!

thnx for the WinEventHook link :mrgreen:

Gui +LastFound
hWnd := WinExist()

DllCall( "RegisterShellHookWindow", UInt,hWnd )
MsgNum := DllCall( "RegisterWindowMessage", Str,"SHELLHOOK" )
OnMessage( MsgNum, "ShellMessage" )

Return ;                                                 // End of Auto-Execute Section //

ShellMessage( wParam,lParam ) {
; Execute a command based on wParam and lParam
}

Hi,
THanks for this. I have a question regarding this? How do I add this code to default Autohotkey script that I use (the one with my regular hotkey /hotstrings etc?)

I tried adding this code as it is at end of the file , it doesn't work however.

Please refer AHK Documentation for 'auto-execute section'.
Revert back if you have a problem in understanding the concept.

Silly me. :oops:
Thanks for the pointer.

[dotslashc]

Unfortunately not working for me still.
I am trying to include some other scripts i found here.

#include %A_ScriptDir%\My Scripts\notifylockunlock.ahk
#include %A_ScriptDir%\My Scripts\iSwitcher.ahk

notify_lock_unlock()
; Calls function "on_lock()" when computer is locked and "on_unlock()" when computer is unlocked

Does location of these lines make difference? My understanding is that #include directive execute the script in included AHK file immediately. Will the return command in included file affect what I am trying to do?

If I put above code before the following code

Gui +LastFound
hWnd := WinExist()

DllCall( "RegisterShellHookWindow", UInt,hWnd )
MsgNum := DllCall( "RegisterWindowMessage", Str,"SHELLHOOK" )
OnMessage( MsgNum, "ShellMessage" )
Return

Then only iSwitcher and notifyunlocklock works. If I put it later only the "RegisterShellHookWindow" code works.

I really want to keep my include files seperate. Any workaround?

[SKAN]

It is preferable that you use #include at the end of the script.

Yup, tried this. Now my iSwitcher script is causing issue. The pretty UI of this script doesn't show up.

Edit: I guess I have no choice but to run iSwitcher in seperate script.
