I've written a custom marshaler for DateTime, but I can't seem to get it to be used with a COM object. Custom marshaling seems straightforward with simple PInvokes; but it seems to be ignored with COM interfaces. i.e. the custom marshaler works fine when I PInvoke a method whose parameter is attributed with MarshalAs...
Custom Marshalers don't support value types directly; they're only supported when they're boxed. On the PInvoke side this means declaring parameters and return values as Object instead of DateTime. This might be why it's not working with COM objects. If I try to declare the managed COM interfaces with Object instead of DateTime it simply causes an exception. So, it /appears/ as if custom marshaling of value types is not supported on COM objects. =================================== This list is hosted by DevelopMentor® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
