Database Extenion : Invalid signature

Postby JamesBond » Tue Apr 14, 2015 2:29 am

Hello


I am trying to create an extension to read time series with JSON format from a web service. I followed the explanation in the note "Eviews Database extension interface". But when I execute the order edxadd, I get the message "Unable to register edxsample.customdbmgr" "CustomDB Database extension has an invalid signature." I checked the registry and DLL has been saved in \HKEY_CLASSES_ROOT\EDXSample.CustomDBMgr


Any ideas?

Thanks

Make sure you are using the latest version of EViews by checking for an update patch (Help->EViews Update)

Also, make sure your sig=xxx line in the attribute string matches exactly the value from the example. Also make sure the feature= value and the description= value all match exactly as well.

Hello Again


I registred edxsamples.customdbmgr succeffully. But when i execute dbopen(type=customdb) f:\edx\test.cdb, i got the message "DataBase Format requires Eviews Enterprise Edition". I have the Standard Edition. So i suppose that i have to migrate to a Enterprise Edition.



Thanks
