I have an ethernet device that I need to communicate with in either vba (access 2003) or visual basic 2008 or visual C++ 2008. I am most familiar with vba, then vb2008, the visual c++ 2008.
I need to open a communication channel with the device, need to send commands to the device, and need to read results from the device.
What are the commands I need to handle this communication? Is it best to use win api or other? I really have limited knowledge on socket type programming. I have only communicated to ethernet devices in character based Unix C using AF_INET structures (about 5 years ago). I handle serial communications using WIn API.
Any help would be greatly appreciated. I am a novice on this subject.
