internet connection dll function

[Detective]

Hi,

What dll file of Windows (and what function)
shows whether you are online?

Detective,

I believe you're looking for the WININET.DLL. There are many materials online for this, but some depend on your version of Windows, WININET.DLL, and (possibly) event your version of IE.

Here are a few resources to help you get started:

(Sorry for the mangled URL).

If you're using Delphi 6, you may also be interested in the Indy components, which make this sort of thing a snap. Here's an intro article:

Hope this helps...
