Maybe you're missing DLL dependencies. Try running DependencyWalker on it.
You you have a .manifest for it, if you haven't try generating one.

I have a similar problem :

Unhandled Exception: System.DllNotFoundException: Unable to load DLL 'js32.dll':
This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1)
at SpiderMonkey.JS.JS_Init(UInt32 maxbytes)
at smnettest.Program.Main(String[] args)

Any idea ?
I use the beta 0.1.5.

New Post: AccessViolationException when trying to call JS_HasProperty

vidarkongsli — Fri, 03 Apr 2009 09:13:50 GMT

I am trying to check for a property on the global object, like so:

IntPtr isWindowDefined = Marshal.AllocHGlobal(Marshal.SizeOf(typeof(bool))); JS.JS_HasProperty(cxPtr, globalClassPtr, "window", isWindowDefined);

I get an AccessViolationException on the second line above. What am I doing wrong?

Thanks,
Vidar

already found it out: my application was missing msvc90.dll :-/
Seems js32.dll is causing it, I fixed it by dynamically creating a reference to it in my manifest at build time :/

Hi,

As soon as I call JS.Init, I get an DllNotFoundException (js32.dll). I tried putting js32.dll in my debug/release/system32 folder, but it didn't work.

Unable to load DLL 'js32.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Any idea what I'm doing wrong here?

NEW POST: Is SM.NET alive?

Takuan — Sun, 12 Aug 2007 17:28:24 GMT

The project seems to be stagnant at the moment :(

The generic object embedding seems to work at a basic level, in the development branch of the latest release. It's still kind of buggy and incomplete, especially with regards to the ability for javascript to attach to events exposed by embedded C# objects, but that's something I was able to resolve locally within a couple of hours (having never perused the code before).

I am sincerely hoping that this project is not dead, because it is absolutely fascinating, and has a great deal of potential.

Hi!

I'm curious if You still develop this great .NET library? I'd really love to see those new nice features (http://www.codepraxis.com/2006/08/preview-of-generic-object-embedding.html) in action!

NEW POST: Licensing

abstraktmethodz — Wed, 23 May 2007 19:57:24 GMT

Martin,

As I understand it SpiderMonkey itself is LGPL, so it can be redistributed with non-free or open source programs/libraries. The basic SpiderMonkey-DotNet stuff has been LGPL'd also so this is obviously compatible. The developer's license I have stamped on the rest of the functionality doesn't grant any rights to redistribute, and so the SpiderMonkey license doesn't really matter to the user as long as I am in compliance.

Meanwhile, SpiderMonkey-DotNet is licensed under a custom license that makes no reference to the above licenses, and is distributed without SpiderMonkey.

I'd appreciate guidance as to how these licenses are intended to interact in this case.

j32.dll is SpiderMonkey engine itself. This project will not be modifying its source. But we do have to build it and debug with it, and so you'll find that source included as another project in the development branch. If you'd like to submit a patch file please send it to derekpetillo@yahoo.com. Thanks

hollowlife1987 — Tue, 26 Sep 2006 02:13:38 GMT

Howdy, I was wondering a couple questions 1.) If you guys edited the js32.dll file, will you release the source code? 2.) How would I submit a source patch? Or do you guys not do that?

User Forum: RE: Attempting To Read or Write Protected Memory

abstraktmethodz — Mon, 25 Sep 2006 14:21:00 GMT

This is a bug not in the binding (as it is), but in the test code. Handling the "CallbackOnCollectedDelegate" errors are a fact of life in interop code, but simply solved. I've already been working at different approaches, so I'll update the test project soon with a fix. In simple situations such as the Customer example, adding the delegates as static instance variables is a good solution.

wildfrog — Mon, 25 Sep 2006 13:38:47 GMT

Ok, so I tested the 0.1.4 version but (if stressed) the problem still remains. It seems to be that some callbacks are performed on delegates that has been collected by the GC. The script I ran was: for (var i = 0; i < 100000; i++) { var c = new Customer();c.name = 'Franky';c.age =32;c.computeReduction();c.age } And the response was: CallbackOnCollectedDelegate was detected Message: A callback was made on a garbage collected delegate of type 'spidermonkey-dotnet!SpiderMonkey.JS+JS_ResolveDelegate::Invoke'. This may cause application crashes, corruption and data loss. When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called.

Ok this should be fixed in 0.1.4.

I've tried to run the 0.1.3 Beta release and some of the recent code check-ins, but all seems to give me a AccessViolationException in JS_EvaluateScript.
