I want to use a VposCOMAPI.dll, written by vs2010, from PB9 or later.

Question

I want to use a VposCOMAPI.dll, written by vs2010,  from PB9 or later.
I use the following code:
OLEObject obj
int ret_code, ret_Code2
obj = create OLEObject
String Auth_code, Rsp_code,  Rsp_msg
ret_code = obj.ConnectToNewObject("VposCOMAPI.dll")
if ret_code <> 0 then
   destroy obj
   messagebox("error", "Error !" + string(ret_code))
   return
else
   obj.apiInit()
   obj.CARD_NO="9999111188882222"
   obj.MERCHANTID = "0909090909"
   obj.executeAuth()
   ret_Code2 = obj.AUTH_RETCODE
   if ret_Code2 = 0 then
       Auth_code = obj.APPROVE_CODE
       Rsp_code = obj.RESPONSE_CODE
       Rsp_msg = obj.RESPONSE_MSG
       messagebox("OK", "OK !")
   else
       messagebox("error2", "Error2 !")
   end if
   destroy obj
end if
I got the ret_code “ Errorcode  -2 ( Class name not found )”.
Anybody could help me ?
Could I use the VposCOMAPI.dll in this way ?
Thanks !
Jack
PS : The VposCOMAPI.dll works in VS2010

Hi,
A few things to remember. They must be 32-bit ComVisible or COM Interop registered assemblies.
You need to use the ProgId to connect to; have you checked if they were visible in the browser?
As Jacob mentions,
These have been discussed before by Bruce, particularly in the PowerBuilder Deveopment Center and in other places.
