OPOS Line Display Service Object

Hi,

I am a newbie in OPOS.

I am developing a service object for OPOS line display. When trying to use it through the MonroeCS CO control (OPOSLineDisplay.ocx, version OposCCOs-1_11_001), Open gives code 104 (=OPOS_E_NOSERVICE), and get_OpenResult() gives code 305 (=OPOS_OR_BADIF).

What these return codes really means ?

In Control Programmer's Guide (OLE for Retail POS, Release 1.6) this is said in page 18, item 5: CLIP --> ... (This ensures that the Service Object supports at least the minimum methods of a valid Service Object for the device class, before calling any of its methods.) CLIP
