InternetGetConnectedState problem

[Spiritofamerica]

I want to see what kind of connection a computer has. To this end I am using the InternetGetConnectedState function(if you have any better ideas I am all ears). char * tip_de_conexiune(void) { char respuns[1024]; DWORD tip_de_conexiune; InternetGetConnectedState(&tip_de_conexiune,0); switch(tip_de_conexiune) { case INTERNET_CONNECTION_LAN: { strcpy(respuns,"lan"); MessageBox(0,"lan","lan",MB_OK); } break; case INTERNET_CONNECTION_MODEM: { strcpy(respuns,"dialup"); MessageBox(0,"modem","modem",MB_OK); } break; case INTERNET_CONNECTION_OFFLINE: { strcpy(respuns,"offline"); MessageBox(0,"offline","proxy",MB_OK); } break; case INTERNET_CONNECTION_CONFIGURED: { strcpy(respuns,"configurat"); MessageBox(0,"configured","proxy",MB_OK); } break; } MessageBox(0,"a","b",MB_OK); return respuns; } this works but it returns none of the predefined values either when I am on or offline. I have a dialup connection. any other way of doing this? or what is wrong with this?

CString sFlags;
if (tip_de_conexiune & INTERNET_CONNECTION_LAN)
  sFlags += "Lan ";
if (tip_de_conexiune & INTERNET_CONNECTION_MODEM)
  sFlags += "Modem ";
if (tip_de_conexiune & INTERNET_CONNECTION_OFFLINE)
  sFlags += "Offline ";
if (tip_de_conexiune & INTERNET_CONNECTION_CONFIGURED)
  sFlags += "Configured ";
 
AfxMessageBox(sFlags);

thanks man it works now when I am online it correctly shows modem configured as in the 2nd and 4th ifs in your code :) but when I am offline it shows nothing it does not show offline why is this man? and everybody else that might know?
