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 <-- Do I have to do the event handling as well as all the methods ? Thanks, Esko Hujanen Ebsolut oy www.ebsolut.fi
Hi, Can any one direct me to the correct direction to write an OPOS Service Object (site or sample file)? I have looked at the www.monroecs.com but did not find any useful info... I am using VC .net 2003 and the current automation server I have written is really not working. Any help would be appreciated. Thank you.
Hi All I have a POS program (Windows app) . I am using VB.net 2005 Pro The OPOS drivers freezes my program if Parallel port is configured for the Receipt printer and the Printer is not connected or is turned off The freezing happens when I try to Claim the device e.g mypos.open(Printername) mypos.claim(300) ***** Happens here if the driver cannot communicate with the Printer mypos.enabled = True There is no connection timeout on the Parallel printer driver for some strange reason and the POS program has to be crashed. Serial and USB versions of the Driver timeout OK Is there anyway to configure a timeout on the driver initialisation routine in my vb.net code, and to kill the driver after say 3 seconds, if the printer is not responding, so my program can continue to load.? Regards Steve
I am in a project that aims to build a opos driver, a species of intermediary between application and opos devices that support the standard. The opos driver is divided in two parts: The Control Object(CO), that makes the interface with application and the Service Object(SO), that makes the interface with the devices. The CO makes methods calls in the SO. My problem is the following one: The CO are ActiveX controls(ocx) and SO are dlls. I am not knowing that type of project I must create in the Visaul c++ and how do I link the CO and the SO? I need them( ocx and dll) will be invisible at runtime. I would like that somebody help about that. Somekind of help is welcome. I wait reply! Grateful! Helio P.S.: for more information about opos standard "monroecs.com/opos.htm"
