I downloaded source code for an old 3ds max plugin from SourceForge and have recompiled it for 2010/2011/2012.  The plugin publishes a particular function to maxscript that takes one parameter of type, TYPE_VALUE.  This parameter is meant to be a stream to which the plugin and attached libraries can output their warning/error messages.  I’ve only tested the plugin in 2012, but when the aforementioned function is called in the plugin’s start-up script:

px.pxSetOutputStream listener —Output all messages to the Maxscript Listener

it throws the error, “No ‘get’ function for <WindowStream>”.  I’ve tried using other Max streams besides the Listener, but with the same issue.  Since this is old code, I’m assuming this function call worked in older versions of Max (R9, 2008, and 2009).

So did the streams used to have a “get” function that has since been removed?  Is there any other way to pass the Listener to the plugin so that all messages can be redirected to it?

Thanks
