Another IAccessibleDLL.dll issue - Win 7

[mxygem]

Heya!

Trying to run RAutomation via a local copy so that I can remove the mandatory 1 second sleep on the send_keys method however when trying to run my test I'm running into the following:

Could not open library 'l:/code/jaysonesmith/RAutomation/lib/rautomation/adapter/win_32../../../../.
./ext/IAccessibleDLL/Release/iaccessibleDll.dll': The specified module could not be found.

      l:/code/jaysonesmith/RAutomation/lib/rautomation/window.rb:67:in `initialize'

If I change to the rubygems version, things work just fine for me. Any idea on what I can do to fix this?

Thanks!

I'm dusting off this library myself so that I can use it on a project and I am running into a similar error. Rubygems copy on Windows 10 for me, however.

[leviwilson]

32-bit ruby?

[mxygem]

Both 32 and 64.

[enkessler]

2.4, 64-bit for me.

C:/Ruby/Ruby24-x64/lib/ruby/gems/2.4.0/gems/ffi-1.9.18-x64-mingw32/lib/ffi/library.rb:147:in `block in ffi_lib': Could not open library 'C:/Ruby/Ruby24-x64/lib/ruby/gems/2.4.0/gems/rautomation-0.17.0/lib/rautomation/adapter/win_32/../../../../ext/IAccessibleDLL/Release/iaccessibleDll.dll': �D� (LoadError)

[leviwilson]

I don't believe 64-bit would ever work because we don't package 64-bit DLLs that are loaded.

That doesn't address the 32-bit one though (haven't had a chance to look).

[enkessler]

Oh. RAutomation just doesn't support 64-bit Ruby at all. That...will be become increasingly problematic as time goes on.

Edit: switching to a 32-bit Ruby 2.4 has things running fine for me, now.

[leviwilson]

Automation would if 64-bit binaries were built and strategically loaded depending on the bit-ness of ruby.

For the uia gem that I wrote, I have a feature branch where I took a stab a long time ago at trying to do this...and it mostly works IIRC but I think I had some issues with the specs that I wasn't quite comfortable with releasing though.

[enkessler]

At the risk of derailing the thread and because I am a simple man: remind me why we use DLLS in the first place instead of going pure Ruby?

[enkessler]

Correction: it worked until I tried switching from the default adapter to the :ms_uia adapter. Now the DLL is having trouble again.

LoadError: Could not open library 'C:/Ruby/Ruby24/lib/ruby/gems/2.4.0/gems/rautomation-0.17.0/lib/rautomation/adapter/ms_uia/../../../../ext/UiaDll/Release/UiaDll.dll': The specified module could not be found.

[leviwilson]

The DLLs are used because straight up win32 calls are not enough to be able to drive automation via UI Automation and require either COM or like we do here, a managed C++ DLL that acts as the bridge into a C# DLL to more reliably interact with UI Automation.

So the absence of x64 is simply because the work hasn't been put in in order to compile both the x86 / x64 DLLs and package them.

The "specified module could not be found" sounds like it's a problem either with running 64-bit rubies or the absence of the 32-bit C++ runtime that is required. I can't exactly recall, but I think this one requires the VC++ 2010 runtime? It's either that or 2012.

Closing this, but added a separate little section to README regarding 32bit vs 64bit Ruby because this issue keeps coming back.
