Re: Datatypes do not work when calling an external DLL procedure

Hello,

I think the problem is that there is a difference in the declaration on the Delphi and Oracle side.
Try changing the calling convention in the Delphi-part from stdcall to pascal. This causes that the parameters are passed in the reverse order. I am not shure if this solves the problem but it is worth trying it

Regards
