Hi list, I try to control a setup which consist of a monochromator and a CCD camera.
[...]
Now if I try to access a monochromator coclass from another libray in the same way I get com_error: (-2147221005. instrument = win32com.client.Dispatch("JYMONOLib.IJYMonoReqd") or instrument = win32com.client.Dispatch("JYMONOLib.Monochromator")
You can use ctypes.WinError to look up the error code if it known to windows: >>> from ctypes import * >>> raise WinError(-2147221005) Traceback (most recent call last): File "<stdin>", line 1, in <module> WindowsError: [Error -2147221005] Ungültige Klassenzeichenfolge >>> In english this would read: 'Invalid class string'. This means that the COM runtime does not know about the "JYMONOLib.IJYMonoReqd" and "JYMONOLib.Monochromator" names.
