Oracle 12560 error on change to dynamic loaded DLL

[clivew]

I have a DLL that has no problem connecting to Oracle on my server when loaded statically.
However, when I load it dynamically I get the above error when trying to log in.
SQLora.log indicates that I am trying to log on locally using (DESCRIPTION=(ADDRESS=(PROTOCOL=BEQ)(PROGRAM=oracle)(ARGV0=oracleORCL)(ARGS='(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))'))(CONNECT_DATA=(SID=ORCL)(CID=(PROGRAM=C:\Delphi32\Votec\Output\SingleScanTwainDyn.exe)(HOST=VTCW01)(USER=clivew))))

This is obviously wrong. It does not happen when the DLL is statically loaded because I connect correctly.

Any advice?

OK. Found the problem.
When re-defining the procs in the calling app. I forgot to add the stdcall.
