Cannot read .dll files when trying to access .cdb via python

SOFiSTiK

Hello
I have a script that i have been using for a long time to access .cdb via python.

But since getting a new computer, it is throwing an error.
I am using this setup:
Configure the project - CDB Interfaces 2024 (sofistik.com)

######################

path = os.environ["Path"]

# 64bit DLLs
dllPath = r"C:\Program Files\SOFiSTiK\2024\SOFiSTiK 2024\interfaces\64bit"
dllPath += ";"

# other necessary DLLs
dllPath += r"C:\Program Files\SOFiSTiK\2024\SOFiSTiK 2024"
os.environ["Path"] = dllPath + ";" + path

# Get the DLL functions
myDLL = cdll.LoadLibrary(r"C:\Program Files\SOFiSTiK\2024\SOFiSTiK 2024\interfaces\64bit\sof_cdb_w-2024.dll")
py_sof_cdb_get = cdll.LoadLibrary("sof_cdb_w-2024.dll").sof_cdb_get
py_sof_cdb_get.restype = c_int

py_sof_cdb_kenq = cdll.LoadLibrary("sof_cdb_w-2024.dll").sof_cdb_kenq_ex 
#End Region
############################

but, now i am gettins this error:

Traceback (most recent call last):

    myDLL = cdll.LoadLibrary(r"C:\Program Files\SOFiSTiK\2024\SOFiSTiK 2024\interfaces\64bit\sof_cdb_w-2024.dll")

FileNotFoundError: Could not find module 'C:\Program Files\SOFiSTiK\2024\SOFiSTiK 2024\interfaces\64bit\sof_cdb_w-2024.dll' (or one of its dependencies). Try using the full path with constructor syntax.

The file “sof_cdb_w-2024.dll” is very obviously in the right location with the right name, i am thinking its something with the dependencies, but i am running out of options here. Anyone have experience with this error?

I figured it out. Even though i was using a python version newer than 3.8 with the old way of calling .dll before, i had to update to the new function for calling .dll.

Hello Morten

what was the problem i am trying to read cdb database too but i am getting errors? i am doing it via c-sharp?

It was importing some files in a different format than before. Took me forever to find the issue.

I dont know about c#, are you following this?

Morten, yes i made my own console programme to read cdb based on this example
I made a sidebar with error methods
I get these errors
I unlocked the base cdb but it still doesn’t open I don’t understand what the problem is.

The methods generate the following errors.

how did you implement this in python? can i try to implement your python approach in c sharpe?

Again, i dont know about C#, but you could switch to python to access the .cdb and get data, once you have data you can run your c#.
That would require two scripts, one python for data retrival, and one in c# for data handling.
