At least one of the arguments for 'IWMPGraphEventHandler.NotifyAcquireCredentials' cannot be marshaled by the runtime marshaler. Such arguments will therefore be passed as a pointer and may require unsafe code to manipulate. RRS feed

  • Question

  • Hi all,
    I have the following warnings when compiling my code(VB10):

    1: Type library importer encountered a property getter 'sessionPlaylistCount' on type 'WMPLib.IWMPNowPlayingHelperDispatch' without a valid return type.  The importer will attempt to import this property as a method instead.

    2: At least one of the arguments for 'IWMPGraphEventHandler.NotifyAcquireCredentials' cannot be marshaled by the runtime marshaler.  Such arguments will therefore be passed as a pointer and may require unsafe code to manipulate.

    How can I fix?

    Thanks
