ICustomQueryInterface..::.GetInterface Method

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Returns an interface according to a specified interface ID.

Namespace: System.Runtime.InteropServices
Assembly: mscorlib (in mscorlib.dll)

Syntax

C++

JScript

Copy to Clipboard Print

'Usage

Dim instance As ICustomQueryInterface
Dim iid As Guid
Dim ppv As IntPtr
Dim returnValue As CustomQueryInterfaceResult

returnValue = instance.GetInterface(iid, _
    ppv)

'Declaration

Function GetInterface ( _
    ByRef iid As Guid, _
    <OutAttribute> ByRef ppv As IntPtr _
) As CustomQueryInterfaceResult

Parameters

iid: Type: System..::.Guid%
The GUID of the requested interface.

ppv: Type: System..::.IntPtr%
A reference to the requested interface, when this method returns.

Return Value

Type: System.Runtime.InteropServices..::.CustomQueryInterfaceResult
One of the enumeration values that indicates whether a custom implementation of IUnknown::QueryInterface was used.

Remarks

An application can use managed code to specify its own implementation for custom interfaces and standard runtime interfaces.

The CustomQueryInterfaceResult return value can be used to enable or disable customized implementations by showing or hiding specific interfaces during COM access.

This method is invisible to COM.
