Given I can't currently easily pass back the interface, I'll leave for some long winter night to test it and maybe find some reasonable hack to wrap some managed code into native interface. Over the wire it works nicely. -- Mgr.

There's nothing after this. No further attempts to load anything. Just exception from Firebird and then my application closes from application side of things. -- Mgr.

That's my problem. I don't think I can marshal the callback interface (I can marshal simple pointer to a function), because I can't create such interface in C#, obviously. :( -- Mgr.

[Firebird-devel] Crypt key callback on Embedded
Hi *, how's the crypt key callback expected to work on Embedded? So far I haven't done anything to the .NET code, but when I try to connect to an encrypted database I get: Error loading plugin Callback Module \plugins/Callback exists but can not be loaded Not sure whether it's because I haven't provided any callback in the first place or it's something else. -- Mgr.
