How to use _WinAPI_AddIconOverlay on my Scripts Tray Icon

Recommended Posts


I have a script that that connects to other computers using a shared network drive.

If access to that shared drive hasn't been updated in a while, or is gone, I want to update the System Tray Icon for my script to have a grey x or red x or green check overlayed on it for a short time.

I can do all this using the _WinAPI_AddIconOverlay example for an Icon in a GUI, but every time I try to apply the overlay to a tray icon I just get a generic system icon.

Is there even a way to save the overlayed icon to a new .ico file so I can set it using the TraySetIcon?

Any ideas?

TraySetIcon will allow you to change the tray icon for your program.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

_WinAPI_SaveHICONToFile() allow you to create .ico file but there is a better way.


#Include <APIConstants.au3>
#Include <WinAPIEx.au3>

Opt('TrayMenuMode', 1)

$hAutoIt = WinGetHandle(AutoItWinGetTitle())

$Exit = TrayCreateItem('Exit')

$hIcon1 = _WinAPI_ShellExtractIcon(@SystemDir & '\shell32.dll', 77, 16, 16)
$hIcon2 = _WinAPI_ShellExtractIcon(@SystemDir & '\shell32.dll', 22, 16, 16)
$hIcon = _WinAPI_AddIconOverlay($hIcon1, $hIcon2)

$tNID = DllStructCreate($tagNOTIFYICONDATA)
DllStructSetData($tNID, 'Size', DllStructGetSize($tNID))
DllStructSetData($tNID, 'hWnd', $hAutoIt)
DllStructSetData($tNID, 'Flags', $NIF_ICON)
DllStructSetData($tNID, 'ID', 1)
DllStructSetData($tNID, 'hIcon', $hIcon)
_WinAPI_ShellNotifyIcon($NIM_MODIFY, $tNID)

While 1
    Switch TrayGetMsg()
        Case $Exit

Thanks Yashied!

That DLLStruct stuff was exactly what I was missing.
