Hello,

I downloaded the FB 2.1.2 sources and opened the fbudf.vcproj in the
msvc8 subfolder.
Compiling and linking worked fine, but exchanging the dll with the
original one always gives
the error:

Invalid token.
invalid request BLR at offset 59.
function DPOWER is not defined.
module name or entrypoint could not be found.

when a external function is called.

Does anybody know how I can write a udf for FB 2.1.2 with Visual Studio 5 ?

Thanks in advance,
FW
