Also see our I2C-OCX control  / interface for Visual Basic 6.0+  I2C-OCX  works with all XP / 2000 / NT / 98 Systems.

Our SOURCE CODE (well documented code VB & C++ ) of the I2C-RTD / I2C-OCX is for sale, this includes the full I2C communication engine (VB) + DLL interface hardware driver source code (C++) this code will work with third party PCI LPT cards on any port number as well as pin numbers, both DLL & Communication Engine can be fully modified. 
Please Note: The communication code is very complicated to make I2C work, you need to have a full understanding of I2C communications for code modification of the module.

THE BIG QUESTION?

Windows Software:   The I2C BUS can be controlled on an Internal CPU I2C bus ONLY with a windows system (ie. API windows software only running I2C devices attached to the CPU). Any EXTERNAL control of  I2C requires some kind of  hardware port, these ports  can not  be accessed by VB unless you use a DLL hardware port driver (ie. RS232, LPT etc). You should not use USB to run a LPT port, you need a real hardware port or hardware port card & the software for the DLL must have in line Kernel Mode (ASM code) to access  the port.     Note:  This requires a real hardware DRIVER that will require system privileges and a "Driver.SYS" (ASM code) file also!    If you want to run at 3.3 volts you will need a voltage down/up converter of some type to run the I2C device, all old type port are meant to run at 5 Volts (LPT or RS232).
