Hi all,

I hope this is the right forum to ask following question.

I am testing IronRuby 0.3 and trying to use ruby(ruby 1.8.7 (2008-08-11  
patchlevel 72) [i386-mswin32]) application which works fine on my XP  
machine. I have given correct paths to IronRuby but I get (The module  
was expected to contain an assembly manifest. (Exception from HRESULT:  
0x80131018)) error when IronRuby try to load assembly.

Here is code how I have initialized runtime:

```
  ScriptRuntimeSetup setup = new ScriptRuntimeSetup();
        setup.LanguageSetups.Add(
            new LanguageSetup(
                typeof(RubyContext).AssemblyQualifiedName,
                "IronRuby",
                new[] { "IronRuby" },
                new[] { ".rb" }
            ));
        ScriptRuntime runtime = new ScriptRuntime(setup);
        ScriptEngine engine = Ruby.CreateEngine();
        List<string> paths = new List<string>();

        paths.Add(@"C:\ironruby\Merlin\Main\Languages\Ruby\Libs");
        paths.Add(@"C:\ruby\lib\ruby\1.8");
        paths.Add(@"C:\ironruby\Merlin\External.LCA_RESTRICTED\Languages\Ruby\redist-libs\ruby\site_ruby\1.8");
        paths.Add(@"C:\ironruby\Merlin\External.LCA_RESTRICTED\Languages\Ruby\ruby-1.8.6p287\lib\ruby\1.8\i386-mswin32");

        engine.SetSearchPaths(paths);
        engine.ExecuteFile(@"C:\test.rb");

```

So am I trying do something which is currently impossible with current  
IronRuby implementation or did I do somekind of configuration mistake?

You can use ironruby-dbi to access databases.  
Or you can use the [ADO.NET](http://ADO.NET) interfaces directly.

## win32ole relies on C-extensions and they don’t work on IronRuby If your application depends on C-extensions they need to be ported to C#.

Thanks for your quick answer.

In my case this means porting to C#.

Mainly there is application handling through command prompt  
(ShellExecute). I should first study more those interop features and of  
course Ruby too cause both are quite new things for me.

What methods and modules do you use from Win32OLE? It might be actually  
easy to implement them in Ruby using our .NET and COM interop features.
