5 lines script and GUIDelete() crashes?!

[milos83]

I am creating a gui and a  ScriptControl in it.

When I run GUIDelete it crashes.

What am I doing wrong?

GUICreate("")
    $sc = ObjCreate("ScriptControl");MSScriptControl.ScriptControl acts the same
    GUICtrlCreateObj($sc, 0, 0)
    GUISetState()

    GUIDelete();hang message: Autoit stopped working!

Not every control can be embedded. They must at least support an 'IDispatch' interface.

Is that the issue here?

As the Danyfirex said, ScriptControl can't be attached to a GUI.

Here is why I wanted to do it,

The ScriptControl is hogging up RAM on a long term usage so I was thinking if I attach it to a GUI and then deleting that GUI would free the memory.

I was also thinking creating a ScriptControl object from another process and then attaching to it so then I would be able to kill the process periodically and clear the memory.

But that never worked since ObjGet can't attach to another proccess obj.

To further clarify, I am using OO_JSON.au3 and it uses a ScriptControl in order to parse JSON.

Its faster than any solution out there but, simply setting a json value in a loop would build up RAM fast. So I'm searching for a solution to clear it.

 

Anyone have a suggestion?

ScriptControl is not an Embeddable ActiveX Control like Windows Media Player.

Hello.  You just need to free it when you're not using it. UDF design is not so good but basically you will need to do this.

Yeah, that is what I was doing.

I would stringify all of the data, 'null' the json and the load the data back in but its not as effective at memory clearing as expected.

Ended up just decreasing the usage of json since it has that memory leak.

Thanks @Danyfirex
