This behavior is by design. MutableString -> object requires an up-cast MutableString -> string requires an explicit conversion
Overload resolver prefers up-cast over an explicit conversion. With explicit conversion you can lose some information (e.g. encoding of the string) and also get an exception (if theMutableString represents binary data not convertible to UTF16 string). The constructor seems to be poorly designed since it actually accepts only objects that implement IWebBrowser2 (you get argument exception "iwebBrowser2 needs to implement shdocvw.IWebBrowser2" if you pass something else). I don't a reason why the constructor shouldn't take IWebBrowser2 parameter.

A work-around currently will be to force the string to be a CLR string: IE.new('http://google.com'.to_clr_string) However, it's unfortunate that IronRuby's CLR overload resolution is picking the more conservative choice, rather than seeing if the Ruby string can be coerced into a more specific overload. JD, have you found this while testing? Tomas, any specific reason this is the behavior, or would you call it a bug? I'd vote it as a bug. This will also work: ie = IE.new ie.go_to 'http://google.com' Here's the C# example ported to IronRuby: require 'Interop.SHDocVw' require 'WatiN.Core' include WatiN::Core ie = IE.new ie.go_to 'http://localhost:1879/Login.aspx' ie.text_field('txtUserName').type_text('azamsharp') I also verified this works from the interactive prompt, so you can use WatiN to control the browser interactively from IronRuby. ~Jimmy ________________________________ From: ironruby-core-boun...@rubyforge.org [ironruby-core-boun...@rubyforge.org] on behalf of Jimmy Schementi [jimmy.scheme...@microsoft.com] Sent: Tuesday, September 22, 2009 11:39 AM To: ironruby-core@rubyforge.org Subject: Re: [Ironruby-core] IronRuby with WatiN By "C# code" i meant the equivalent C# program that you said worked: azamsh...@gmail.com<mailto:azamsh...@gmail.com> wrote: > I created a C# application and used WatiN.
