I created a Delphi DLL using your suggestion and placed it in the
Firebird UDF folder. I then declared it in me schema as so.

declare external function IntToHex
integer
returns
cstring(254)
entry_point 'IntToHex' module_name 'XpressUDF.dll';

and get the following error.

ISC ERROR MESSAGE:
invalid request BLR at offset 116
function INTTOHEX is not defined
module name or entrypoint could not be found

Any suggestions?
