Yes, that is possible. Look at the ctypes documentation within the
Python documentation, or Google for examples. If your VB DLL is a COM
server, however, you would use another method to access it, e.g.,
comtypes. That package is not installed with Python, but a web search
will find it.

Thanks a lot.
How to call function MyFunc in the MyDll.dll which was created in VB6,
not
function from user32.dll ? How to send the string to function, and get
back
string as return value? Is that possible from Python?
Sorry, my English is not good. Translation I made with EdSharp program.
With
his command, it is now easy.
Thank you again,
Dragan.
