>From the "wanted 1, got 0" message, it appears that the problem is that
Python first checks to see if there is a *property* named 'mypingmax' before
checking if it is a method.  The way Python works, that is hard to avoid.
If the app returned a "normal" error code in that case things would march on
fine.

You could try calling the _FlagAsMethod method on the object.  Something
like:

o = win32com.client.Dispatch("MAX.Application.8")
o._FlagAsMethod("mypingmax")
o.mypingmax("test string")

That should prevent win32com from first checking if the item is a property.
