In former times whenever I had opened a database in Valentina Studio and then in my app I got an exception. This doesn't happen in V4X 6. Instead opening happens normally and I get an exception when I first do a select. Is this a bug or a feature?

Mit freundlichen Grüßen/Regards

Yes, it is intentionally so. Your app is opening the db in read-only mode.

Thanks for the information.

What would be the best way to prevent opening in read-only mode? Can I control this? Or I immediately try to write to the database after opening...

No, it is not. vKernel tries to open file in RW mode and in case of failure tries to open it in RO.

Hi Ivan,

I'd rather have an exception than the database doing something it shouldn't. Okay, I'll go with the idea of trying to write something to the database.

You may ask database - IsReadOnly instead of trying to write down something.
