BTW, PyObject po = PythonEngine.RunString(strCommand); returns 'null' when
running "os.getcwd()", and PythonEngine.RunSimpleString(strCommand) returns
'-1'.
Currently, I'm working on Async ways to execute a python command (some
commands take long to finish a task such as switch configuration, once
executing a command, and returns, then gets a result later).
Would you give me some suggestions how/what would be best idea for Async
wrapper using Python.RunTime?
Thanks,
Spark.
