Örnekler

Aşağıdaki örnekte, sarmalayıcı efekt nesnesini almak için yöntemini kullanan CreateBitmapEffectOuter bir uygulaması CreateUnmanagedEffect gösterilmektedir.

unsafe protected override SafeHandle CreateUnmanagedEffect()
{
    const uint CLSCTX_INPROC_SERVER = 1;
    Guid IID_IUnknown = new Guid("00000000-0000-0000-C000-000000000046");
    Guid guidEffectCLSID = new Guid("84CF07CC-34C4-460f-B435-3184F5F2FF2A");
    SafeHandle wrapper = BitmapEffect.CreateBitmapEffectOuter();

    COMSafeHandle unmanagedEffect;
    uint hresult = Ole32Methods.CoCreateInstance(
                        ref guidEffectCLSID,
                        wrapper.DangerousGetHandle(),
                        CLSCTX_INPROC_SERVER,
                        ref IID_IUnknown,
                        out unmanagedEffect);
    InitializeBitmapEffect(wrapper, unmanagedEffect);
    if (0 == hresult) return wrapper;
    throw new Exception("Cannot instantiate effect. HRESULT = " + hresult.ToString());
}

Protected Overrides Function CreateUnmanagedEffect() As SafeHandle
    Const CLSCTX_INPROC_SERVER As UInteger = 1
    Dim IID_IUnknown As New Guid("00000000-0000-0000-C000-000000000046")
