>Hello, does and body know a function in a DLL that can check if DialUp networking is intiated or not?

I've used InternetGetConnectedState(), but the results have not been consistent, and Rick Strahl reports that the wrapper is flakey. You can experiment with it, though - the API prototype is:

DECLARE SHORT InternetGetConnectedState IN WININet.DLL ;
    INTEGER @lpdwFlags, ;
    INTEGER dwReserved
nFlags = 0
nResult = InternetGetConnectedState(@nFlags, 0)

returns 1 on success, 0 if failed, and you need to check the flag values returned in the parameter nFlags using the values in WININET.H; 1 indicates a modem connection, 2 a LAN connection, 4 a proxy server connection, 8 modem in use busy, and zero means no connection exists. I've gotten incorrect results when DUN was trying to establish a link; it reported a connection even though it was in the process of dialing.
