COM automation and interop for AHK v2 — driving Excel / Word / WMI / Internet Explorer via IDispatch, COM events, ComValue / SafeArrays, and direct vtable ComCall. Use when automating another application, wiring COM events, or calling a COM interface. TRIGGER when: user says "automate Excel/Word", "COM object", "ComObject", "ComCall", "WMI query", "COM event", "IDispatch", "SafeArray", "ComValue", "VARIANT". Examples: "automate Excel from AHK", "query WMI for processes", "hook IE navigation events"

AHK v2 COM Automation

Drive another application's object model from AHK.

How to use

1. Load the full reference from Modules/Module_COM.md — creation, events, ComValue, SafeArrays, vtable ComCall.
2. Create with ComObject("ProgID") (never the removed ComObjCreate); the wrapper auto-releases on scope exit.
3. For headless work set obj.Visible := false / obj.DisplayAlerts := false, and obj.Quit() apps like Excel.
4. For COM events, ComObjConnect(obj, sink) where the sink's method names match the event names.

Quick answers

• Create: xl := ComObject("Excel.Application"); moniker bind: ComObjGet("winmgmts:").
• Typed value / ByRef: ComValue(3, n) (VT_I4); ComValue(0x4000 | 3, &out) (ByRef).
• No IDispatch (low-level / WinRT): call vtable slots with ComCall(index, obj, ...) — see Module_WinAPI.md for WinRT.

For events, SafeArrays, the VARENUM table, and cleanup rules, read Modules/Module_COM.md.
