I am trying to import a user-defined function (UDF, hereafter) through xlwings add-in. That UDF is using a DLL (in the form of .pyd). When I try to import the UDF into excel through xlwings add-in, I am facing a run-time error.
The below is the Visual Basic Error message:
-2147467259(80004005) run-time error ImportError : DLL load failed import BS1DCallPut ... File "", line 222, in -call_with_frames_removed
Actually the error is occurring in the part of importing the DLL.(BS1DCallPut.pyd is the name of the DLL)
There's no problem with that DLL elsewhere. For example, I can perfectly import that DLL in a Jupyter notebook and can do some calculations with it, no problem.
