Exporting Datasocket Communication to DLL

[Adrien2000]

I wish to communicate to a datasocket in python. My current approach is by making a VI which opens the data socket, writes to in and then closes it (VI attached). 

I am pretty sure that repeatedly opening and closing the datasocket is causing problems- eventually the communication stops working and reading from it returns a blank array (both in labview and in python).

I was wondering if there was a way to split up the VI into smaller functions for the DLL, such that the datasocket communication can be maintained in python, in order to prevent this problem.

I appreciate any help anyone may be able to offer.

I would like to recommend avoiding heavy-weight DLLs exported from LabVIEW and instead using the lightweight DataSocket implementation from NI CVI:

DataSocket Library Function Tree.

By default installed

Header: "C:\Program Files (x86)\National Instruments\CVI2020\toolslib\datasock\dataskt.h" 

Library: "C:\Program Files (x86)\National Instruments\CVI2020\toolslib\datasock\msvc\dataskt.lib" 

DLL: C:\Windows\SysWOW64\dataskt.dll

Unfortunately, I do not have a 32-bit LabVIEW in my hands to provide an example, but it should work. I recommend avoiding very complicated data structures.
