Remarks
Use to wrap objects the marshaler should marshal as a VT_DISPATCH
. This wrapper will force objects to be marshaled out as VT_DISPATCH
. If the object does not support IDispatch
then an exception will be thrown.
void MyMethod(Object^ o);
void DoWrap()
{
Object^ o = gcnew MyObject();
MyMethod(o); // passes o as VT_UNKNOWN
MyMethod(gcnew DispatchWrapper(o)); // passes o as VT_DISPATCH
//...
}
void MyMethod(Object o);
public void DoWrap()
{
Object o = new MyObject();
MyMethod(o); // passes o as VT_UNKNOWN
MyMethod(new DispatchWrapper(o)); // passes o as VT_DISPATCH
//...
}
Sub MyMethod(o As Object)
' handle object ...
End Sub
Public Sub DoWrap()
Dim o As Object = new MyObject()
MyMethod(o) ' passes o as VT_UNKNOWN
MyMethod(new DispatchWrapper(o)) ' passes o as VT_DISPATCH
'...
End Sub
For more information on VT_DISPATCH
, please see the existing documentation for VARENUM::VT_DISPATCH
in the MSDN library.
