Example Python Scripts Calling Ez_B.Dll

Hi,

These are intended to be for guidance only, so others can get the idea of how to convert C# or VB into Python. They are probably only useful to people who already use Python.

First step in to install IronPython from here: https://ironpython.net/download/ Ironpython is simply a version of Python with extra .NET bindings.

At the IronPython Command prompt paste in one of the scripts below.

Enjoy!

David.
