Error: 0x80004003 - Invalid pointer Source: SciterSharpWindows Description: Object reference not set to an instance of an object. Specifically: CreateMainWindow

[FuPeiJiang]

hi, I'm coming from FuPeiJiang/ahk_parser.js#22

I've cloned the repo

I've downloaded
sciter.dll 8.23MB
SciterSharpWindows.dll 161.50KB
I've copied these files into the folder ahk-sciter-js\

I run using AutoHotkeyU64.exe with WorkingDir ahk-sciter-js\
note: that was AHK_L v1 version 1.1.33.09

I'm getting this error

can you explain this error ?

using a debugger: I look at variables:
sci

Assembly
  Value:91946016
  VarType:9
  DispatchType:"_Assembly"
  DispatchIID:"{17156360-2F1A-384A-BC52-FDE93C215C5B}"

sciwin

Object
  Value:91945752
  VarType:9
  DispatchType:"IUnknown"
  DispatchIID:"{00000000-0000-0000-C000-000000000046}"

sciwin DispatchIID doesn't seem normal: it has too many zeros

Sciter is constantly undergoing breaking changes. Fortunately this older version should work. It was current at the time I made this repo.

[FuPeiJiang]

thank you, works now

https://www.fuget.org/packages/SciterSharpWindows/3.0.0/lib/net45/SciterSharpWindows.dll/SciterSharp/SciterWindow
I can see the methods

so are we dependent on SciterSharpWindows ?
even if we changed to the updated method names, it still wouldn't work? because we need SciterSharpWindows to call them?

[GirkovArpa]

It does appear to be dependent on SciterSharpWindows, yes. I am not sure what "updated method names" refers to. Are you trying to use the latest version of Sciter?

[FuPeiJiang]

sorry, I assumed that the breaking changes were that "the method names were changed to something else"
and it's not a method name, it's a class name SciterWindow
I assumed that SciterWindow was renamed, that's why it didn't work

but I have no clue what actually changed (what are the breaking changes)

Are you trying to use the latest version of Sciter?

I won't try, I just need a working AHK_v1 script, to be able to verify if AHK_v2 conversion works correctly

[GirkovArpa]

I am not sure what the breaking changes are either. In such cases I usually just download the required version and call it a day 😄

[FuPeiJiang]

can you update README ?
change
[sciter.dll](https://github.com/c-smile/sciter-js-sdk/blob/main/bin/windows/x64/sciter.dll)
to
[sciter.dll](https://github.com/c-smile/sciter-js-sdk/blob/e1909ed966b585466bd235994f00a80ed58f30df/bin/windows/x64/sciter.dll)

"newest version of sciter.dll has breaking changes, this version should work"
