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.
