Currently there is no support (from what I've seen) for attaching watir to an embedded IE window. Several users have had a need for this and I've done some research on the issue but have not yet been able to get a working solution. What would be nice is to add a new method to watir called something like attach_embedded(how, what) where how could be :title or :hwnd and what being the corresponding value autoit has a function for attaching to an embedded browser and I've tested that it works. Thus, In autoit IE.au3 they have a function which when given a hwnd will return the IE control which if we could do the same thing with watir, we could bind that and control it like a regular browser. The following has the source for IE.au3, if you look there is a function called __IEControlGetObjFromHWND which is what I am referring to. Check it out: http://www.therks.com/autoit/install/Include/IE.au3 A few people have attempted to implement this function but have been unable to call the idispatch interface method that is returned (at least, thats what i think the problem is). Here is the most recent attempt which didnt work in my tests: http://rubyforge.org/forum/forum.php?thread_id=33188&forum_id=319 I've compiled some useful links about the issue and I'll post them here: http://groups.google.com/group/watir-general/browse_thread/thread/479a9e9e608c009 http://www.wolfewebservices.com/blog/attaching-watir-embedded-ie-browser http://rubyforge.org/tracker/?func=detail&atid=1700&aid=8437&group_id=426 http://www.bsalsa.com/ie_tools_auto.html http://msdn.microsoft.com/en-us/library/dd373605(VS.85).aspx http://support.microsoft.com/kb/q249232/ http://social.msdn.microsoft.com/forums/en-US/clr/thread/0d2e200d-d39d-453a-ad43-029d2f20d15e/ http://www.nabble.com/write-COM-clients-in-Ruby-td10986533.html I've also seen some code related to modal dialogs which looks like it may have been trying to accomplish the same thing but I wasn't sure.
