Paul,
There are some methods you could use to accomplish what you are doing.

1. You already have the control on a form (or some other type of container) you could write a function that instantiates this control and calls the proper methods from the ActiveX control.

Like:
x = createobject("conBarcodeContainer")
x.printbarcode()

BUT:

You are probably trying to print the barcode on your report. I have a better solution to this problem. Acquire a barcode Font. One company I know of is www.azalea.com. They have code written for FoxPro and VB and their fonts work pretty darn well. There are others though.

Hope this helps.
