What it says - it can't find the module or, if it's finding the
module, it can't find the entrypoint for the function. The
declaration looks OK, so use isql SHOW FUNCTIONS to confirm that the
declaration is committed. It's possibly just a case of not having
all the ducks lined up, viz.

1. On Windows, the module's file name must be 'Project1.dll'
2. In Firebird.conf, the parameter of interest is UDFAccess. The
default for this is Restrict UDF, meaning that the engine will look
for modules only in $firebirddir\UDF. If you placed the DLL
somewhere else, you will need to uncomment the default, add a
semicolon to UDF (which is a relative path) and then append the full
path to where your DLL is.
3. Any changes you make in firebird.conf will take effect only after
the server has been stopped and restarted. Shutting down the
database is not enough.
