   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 &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 QuickPDFUnlockKeyA (INPUT <licence key>, OUTPUT i). // An A at the end of the file name. 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?
