Calling a .Net library in python?
Hi I am trying to send commands from python to a New Focus Picomotor controller.
The commands for the controller are supposedly stored in a .dll library which I have. Is there a way to load this library and call the functions within it?
I am supposed to first initialise the controller to start communication. Which involves calling the function 'CmdLib8742'
I am given a list of the CmdLib Api, which gives a list of constructors and methods that are supposedly called by an language that can support calling a function from within a .NET library.
I know I am supposed to use ctypes. But multiple solutions listed on overflow seem to give me an error saying "Attribute error, function not found"
This is an example of the first two.
/// <summary>
/// Constructor.
/// </summary>
public CmdLib8742 ()
/// < summary >
/// Constructor.
/// < /summary >
/// < param name="logging" >True to request logging, otherwise false.< /param >
/// < param name="msecDelayForDiscovery" >The number of milliseconds to wait for devices to be discovered.< /param >
/// < param name="deviceKey" >The first device in the list of open instruments (null = none found).< /param >
public CmdLib8742 (bool logging, int msecDelayForDiscovery, ref string deviceKey)
