C# vs Python

C# vs Python

Postby ReversE_3ngineeR » 20 Apr 2016, 00:00

Recently got Mk 2/4 to automate some measurements for research. In undergrad I worked as research assistant and made some code in C# for a grad student to make a Mk 2/4 do some scanning similar to what I'll be doing. I've been .NET my whole programming career so I was thrilled to see C# API, but I'm really getting into and loving Python lately. Anyone know pros/cons to interfacing with Python? For example, not knowing position or something when there is a function for it in the C# API? Python's ease of use and cross-platform compatibility make it look like a real winner to me.

The case here is, if Python is able to use API Windows files...

you should be able to use ctypes in Python handling the API if its in solid DLL.

Code: Select all
import ctypes

# Load DLL into memory.

hllDll = ctypes.WinDLL ("c:\\PComm\\ehlapi32.dll")

# Set up prototype and parameters for the desired function call.
# HLLAPI

hllApiProto = ctypes.WINFUNCTYPE (
    ctypes.c_int,      # Return type.
    ctypes.c_void_p,   # Parameters 1 ...
    ctypes.c_void_p,
    ctypes.c_void_p,
    ctypes.c_void_p)   # ... thru 4.
hllApiParams = (1, "p1", 0), (1, "p2", 0), (1, "p3",0), (1, "p4",0),

# Actually map the call ("HLLAPI(...)") to a Python name.

hllApi = hllApiProto (("HLLAPI", hllDll), hllApiParams)

# This is how you can actually call the DLL function.
# Set up the variables and call the Python name with them.

p1 = ctypes.c_int (1)
p2 = ctypes.c_char_p (sessionVar)
p3 = ctypes.c_int (1)
p4 = ctypes.c_int (0)
hllApi (ctypes.byref (p1), p2, ctypes.byref (p3), ctypes.byref (p4))
