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())
End Function
Keterangan
Interaksi kerangka kerja dengan efek kustom ditangani melalui objek IMILBitmapEffect . Efek luar diinisialisasi dengan efek kustom melalui InitializeBitmapEffect metode .
