Make a get call via the WINSNMP API to retrieve the os version from a remote machine.
VBDNFW2SNMP is a quick attempt to use the winsnmp api to retrieve information from remote snmp agents. This example uses VB .Net 2005 with the .Net framework 2.0
Background
Most of the examples I found on the net used WMI instead of api calls, and the older VB6 code used winsock. After many, many hours of searching and putting pieces of info together, i could finaly make a get call to a remote snmp agent. The most valuable resources were:
