) As Integer
'Utilisation
Dim instance As IVsWindowFrame
Dim riid As Guid
Dim ppv As IntPtr
Dim returnValue As Integer

returnValue = instance.QueryViewInterface(riid, _
    ppv)

int QueryViewInterface(
    ref Guid riid,
    out IntPtr ppv
)

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

function QueryViewInterface(
    riid : Guid, 
    ppv : IntPtr
) : int

Parameters

riid

[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.

Remarks

COM Signature

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.
