Visual Basic & OPOS

[BRIAN MARSALIA]

Good Afternoon

Needing some help, Im designing a POS program using OPOS for hardware interaction. Im very new to this, right now Im just trying to write code for the Line display. I have placed the service reference in the program and this is the basic code im using. I have IBM POS hardware and using their config program to give the device a logical name. But still cant get it to work. Again very new with this, any help would be appreciated.

Testvfd = CreateObject("OPOS.LineDisplay")
Testvfd.Open("LD")
Testvfd.Claim(1000)
Testvfd.DeviceEnabled = 1
Testvfd.DisplayTextAt(0, 0, " Test Display", 0)
Testvfd.close()

Im just trying to understand the basic interaction.
