Hi,

I don't know if the way you try to access your DLL is the right one...

Here is how I do : I declare the DLL methods into my .p file as "EXTERNAL" and I specify its parameters.

Here's an example with my DLL written in C++ :

PROCEDURE initSess EXTERNAL "maDLL.dll" CDECL PERSISTENT:
  DEFINE INPUT PARAMETER a1 AS CHARACTER.
  DEFINE INPUT PARAMETER a2 AS LONG.
END PROCEDURE.

Then I call the procedure as a "normal" Progress one, with RUN...

Hope that helps !
