Protected Shared Sub InitializeBitmapEffect (outerObject As SafeHandle, innerObject As SafeHandle)
- outerObject
- SafeHandle
The outer IMILBitmapEffect wrapper to initialize.
- innerObject
- SafeHandle
The inner IMILBitmapEffectPrimitive.
- Attributes
The following example shows an implementation of CreateUnmanagedEffect that uses the InitializeBitmapEffect method to initialize the wrapper object with the custom effect.
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());
}
