Your object would need to implement the IConnectionPointContainer and IConnectionPoint interfaces. In order to do that, you would need to construct the object yourself, including an IUnknown interface implementation which can be queried for those interfaces. You could not simply pass an AutoHotkey object to the client.

It seems I never said anything.
I'm very greatful to you for this function. It has been used in several projects of mine and really makes coding more powerful.

(Sorry for the previous post which I deleted as it had no useful information)

It seems the code below causes memory leaks. I'm guessing ObjRegisterActive() or ComObjActive() is something to do with it.


Code: Select all

#SingleInstance, Force

loop {


testMemoryLeak() {
    _sGUID         := CreateGUID()
    _o := new TestObjRegisterActive
    ObjRegisterActive( _o, _sGUID )

    _sPath         := A_ScriptDir "\Remote.ahk"
    Run, "%A_AhkPath%" "%_sPath%" %_sGUID%,, UseErrorLevel, _iPID    
    ; Wait for the remote script to be activated
    while ! _o.oRemote {
        sleep 10
    ; ( doing something in an actual script )
    ; Done with the remote script
    ObjRegisterActive( _o, "" )
    return _iPID

class TestObjRegisterActive {
    oRemote := ""
    __New() {
        this.TickCount := A_TickCount
    activate( sRemoteGUID ) {    
        this.oRemote := ComObjActive( sRemoteGUID )
        tooltip % "(From Main) Actiavted: " sRemoteGUID

Code: Select all

#SingleInstance, Off

_sMainGUID       := %0% ; script argument

_oMain           := ComObjActive( _sMainGUID )

_oRemote         := new Remote
_sRemoteGUID     := CreateGUID()
ObjRegisterActive( _oRemote, _sRemoteGUID )

_oMain.activate( _sRemoteGUID )

ObjRegisterActive( _oRemote, "" )

tooltip % "From Remote: " _oMain.TickCount


class Remote {
    exit() {
        _func := ObjBindMethod( this, "_exitApp" )
        SetTimer, % _func, -1
        _exitApp() {

Yes. It's easy to do from VBScript. However, it seems GetObject() requires a ProgID rather than a CLSID, so you need to register it in the registry.

Code: Select all

' First set HKCR\testy\CLSID (default value) to the GUID
set x = GetObject(,"testy")
x.Message("Hello, world!")

Apparrently according to this site:

http://web.archive.org/web/200210011332 ... /index.asp

You can also use:

Code: Select all

Set o = GetObject(, "clsid:5c172d3c-c8bf-47b0-80a4-a455420a6911")
A full example can be found here

Code: Select all

Sub CreateGorillaAndEatBanana()
  Dim gc as IApeClass
  Dim ape as IApe
  Dim sz as String
  sz = "clsid:571F1680-CC83-11d0-8C48-0080C73925BA:"
' get the class object for gorillas
  Set gc = GetObject(sz)
' ask gorilla class object to create a new gorilla
  Set ape = gc.CreateApe()
' ask gorilla to eat a banana
End Sub
I've had no luck with either using CLSID or PROGID sadly (in vba), I just receive "Runtime error 429 - ActiveX component can't create object", which seems a bit odd, but perhaps it's due to IT policy or something **shrug**

If the object does not respond, the crash screen of windows appears. But instead of that screen, can I request the called script file to close automatically? I don't want to see the windows crash message because with my main script I can see that the object is still not healthy and restart it.

I'm talking about this kind of crash.

My goal is to create an isolated process against crashes. Even if there is a crash, the user can continue the process from where it left off without realizing it. The main script will create the object again.

I managed to solve it in a different way.

I wonder if anyone knows how to use it with Python? Or is it already impossible?

Very nice function, but it doesn't work with Class_SQlite object and Neutron object with NeutronObj.wnd.function() even though, they are all ahk object. Any idea why?
