Assembly: Microsoft.VisualStudio.Shell.Interop (in Microsoft.VisualStudio.Shell.Interop.dll)

Syntax

int QueryViewInterface(
	[InAttribute] Guid% riid,
	[OutAttribute] IntPtr% ppv
)

riid: Type: System::Guid
[in] Identifier of the window frame being requested.

ppv: Type: System::IntPtr
[out, iid_is(riid)] Address of pointer variable that receives the window frame pointer requested in riid.

Type: System::Int32

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

From vsshell.idl:

HRESULT IVsWindowFrame::QueryViewInterface(
   [in] REFIID riid,
   [out, iid_is(riid)] void ** ppv
);

Similar to the implementation of QueryInterface, except that you are calling on ViewHelper.
