Contoh

Contoh berikut menunjukkan implementasi CreateUnmanagedEffect yang menggunakan metode untuk mengambil objek efek pembungkus CreateBitmapEffectOuter .

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());
}

<SecurityPermissionAttribute(SecurityAction.Demand, Flags := SecurityPermissionFlag.UnmanagedCode)>
Protected Overrides Function CreateUnmanagedEffect() As SafeHandle
    Const CLSCTX_INPROC_SERVER As UInteger = 1
    Dim IID_IUnknown As New Guid("00000000-0000-0000-C000-000000000046")
    Dim guidEffectCLSID As New Guid("84CF07CC-34C4-460f-B435-3184F5F2FF2A")
    Dim wrapper As SafeHandle = BitmapEffect.CreateBitmapEffectOuter()

    Dim unmanagedEffect As COMSafeHandle
    Dim hresult As UInteger = Ole32Methods.CoCreateInstance(guidEffectCLSID, wrapper.DangerousGetHandle(), CLSCTX_INPROC_SERVER, IID_IUnknown, unmanagedEffect)
    InitializeBitmapEffect(wrapper, unmanagedEffect)
    If 0 = hresult Then
        Return wrapper
    End If
    Throw New Exception("Cannot instantiate effect. HRESULT = " & hresult.ToString())

Keterangan

Interaksi kerangka kerja dengan efek kustom ditangani melalui objek IMILBitmapEffect . Efek luar diinisialisasi dengan efek kustom melalui InitializeBitmapEffect metode .
