Hi,

is it possible to use this great library in OpenEdge (vers. 10.2A) as EXTERNAL library?

I am trying to call functions from library but no chance.

&SCOP DLL 'QUICKPDFDLL.DLL'

PROCEDURE QuickPDFUnlockKey EXTERNAL {&DLL} :
DEF INPUT PARAM LicenceKey AS CHAR.
DEF RETURN PARAM iRetValue AS LONG.
END PROCEDURE.

DEF VAR i AS INT NO-UNDO.

RUN QuickPDFUnlockKey (INPUT <licence key>, OUTPUT i).

Any ideas? please.

I assume you are using QPL 8.13 or 8.14.

Can you try the following

QPL 8.xx versions use Unicode/ UTF-16 based strings for most functions. Some development tools such as FoxPro don't have native support for Unicode strings. Every QPL function that has a Unicode string as input or output now has a matching A function that accepts and returns 8 bit strings.

UnlockKey -> UnlockKeyA

LoadFromFile -> LoadFromFileA

Thank you.

I trying to use QPL8.12 and older version 7.21.

I still cannot open the library. Do you know the OE Progress?

I tried to open my own DLL library but same results: "Could not find the entrypoint <functionname>".

What do I wrong?
