How to build uiadll.dll again from command line? I'm currently seeing these errors when trying to do that with msbuild and .sln:

c:\users\jarmo\documents\projects\ruby\rautomation\ext\uiadll\uiadll\stdafx.h(16): fatal error C1083: Cannot open include file: 'atlb ase.h': No such file or directory [C:\Users\Jarmo\Documents\Projects\Ruby\RAutomation\ext\UiaDll\UiaDll\UiaDll.vcxproj]

Added some inline comments to the code too.

Were you able to get this to build? Opening a VS2010 command prompt and running msbuild UiaDll.sln worked for me.

I will try to work on this later tonight then.

I can't build it since i'm using VS 2010 Express edition. It seems that Express edition does not include ATL, which is included by that project. Can we remove these dependencies or are they really needed?

Similar problem is located at SO http://stackoverflow.com/questions/11081917/atlbase-include-doesnt-work

[leviwilson]

Just remove the atlbase.h from stdafx.h and see if it compiles. I think I originally added it when I was using CComPtr<T>, but I am not using that anymore since I'm using MC++ and .NET for the automation.

Now i'm seeing different errors:

[leviwilson]

Rather than using CComPtr<T> in ToggleStateHelper.cpp, change it to look like this:

BOOL ToggleStateHelper::IsSet(IUIAutomationElement* automationElement)
{
  IToggleProvider* togglePattern;
  HRESULT hr = automationElement->GetCurrentPattern(UIA_TogglePatternId, (IUnknown**)&togglePattern);

  if (FAILED(hr)) {
    printf("RA_GetIsSet: getCurrentPattern failed 0x%x\r\n");
    return FALSE;
  }

  ToggleState  RetVal ;
  hr = togglePattern->get_ToggleState(&RetVal) ;
  togglePattern->Release();
  if (FAILED(hr)) {
    printf("RA_GetIsSet: get_ToggleState failed 0x%x\r\n", hr);
    return FALSE;
  } else {
    return RetVal;
  }
}

All the CComPtr<T> does is auto-release COM pointers. It's the equivalent to just call Release() on it before the method returns.

This did the trick! :+1: Thanks!
