How to detect network connection?

[Wenrich]

Hi! How to detect whether the network connection is available for a machine running Win2K? What is the API i can use? Thanks a lot!

This depends on what you are using the network connection for. If you want to use WinSock to talk to a remote machine, you can use a ping function. For example, this article[^] provides a C++ class for doing pings. If you need to see if a given network share is available, just try to do a CreateFile or OpenFile on it. You could also use the functions in the Windows shell[^] to enumerate the contents of the 'Network Neighborhood' to find out what shares are available to your machine. In other words, the simple approach is to assume that the network connection is there, and attempt the operation you are interested in. If the operation fails when it otherwise should succeed, in all likelihood the network connection isn't available.
