IMetroMode is obsolete in Win8 RC

Question

Hi,

I've upgraded to Windows 8 RC build 8400 + VS Pro 2012 RC

I see that there is no more IMetroMode 

I'm trying to use IExecuteCommandHost instead (call GetUIMode)  using CLSID_AppVisibilty (couldn't find CLSID_ExecuteCommandHost) and it fails in CoCreateInstance

Thanks,

Haim.

My code is:

IExecuteCommandHost *pImmersiveMode = NULL;

HRESULT hr = CoInitializeEx(NULL, COINIT_MULTITHREADED);// COINIT_APARTMENTTHREADED - doesn't work

if(FAILED(hr))

{

return EMS_Invalid;

}

hr = CoCreateInstance(CLSID_AppVisibility, nullptr, CLSCTX_INPROC_SERVER, IID_PPV_ARGS(&pImmersiveMode));

if(FAILED(hr))

{

return EMS_Invalid;

}

Answer 1

I've exactly the same problem. IMetroMode is no longer defined in Shobjidl.h

Answer 2

I think next code should work:

{

#if (VER_PRODUCTBUILD >= 8400)

IAppVisibility *pImmersiveMode = NULL;

#else

IMetroMode *pImmersiveMode = NULL

#endif

if(NULL == pImmersiveMode)

{

// Create the immersive mode component

HRESULT hr = CoInitializeEx(NULL, COINIT_MULTITHREADED);

if(FAILED(hr))

return EMS_Invalid;

#if (VER_PRODUCTBUILD >= 8400)

hr = CoCreateInstance(CLSID_AppVisibility, nullptr, CLSCTX_INPROC_SERVER, IID_PPV_ARGS(&pImmersiveMode));

#else

hr = CoCreateInstance(CLSID_MetroMode, nullptr, CLSCTX_INPROC_SERVER, IID_PPV_ARGS(&pImmersiveMode));

#endif

if(FAILED(hr))

return EMS_Invalid;

}

I have a question regarding the meaning of GetAppVisibilityOnMonitor

What is the description of next monitor modes: MAV_APP_VISIBLE, MAV_UNKNOWN, MAV_NO_APP_VISIBLE

Thanks

The document does not updated to have those APIs descriptions, I just know those APIs from this sample code: http://code.msdn.microsoft.com/windowsdesktop/Start-screen-visibility-b1a72059#content

I think this function is what you wanted.
