Retrieving the Connection Name

Windows NT/Windows 2000

To retrieve the name of the network resource associated with a local device, an application can call the WNetGetConnection function, as shown in the following example. The sample calls an application-defined error handler to process errors, and the TextOut function for printing.

CHAR szDeviceName[80]; 
DWORD dwResult, cchBuff = sizeof(szDeviceName); 
 
// Call the WNetGetConnection function.
//
dwResult = WNetGetConnection("z:", 
    (LPSTR) szDeviceName, 
    &cchBuff); 
 
switch (dwResult) 
{ 
    //
    // Print the connection name or process errors.
    //
    case NO_ERROR: 
        TextOut(hdc, 10, 10, (LPSTR) szDeviceName, 
            lstrlen((LPSTR) szDeviceName)); 
        break; 
    //
    // The device is not a redirected device.
    //
    case ERROR_NOT_CONNECTED: 
        TextOut(hdc, 10, 10, "Device z: not connected.", 24); 
    //
    // The device is not currently connected,
    //  but it is a persistent connection.
    //
    case ERROR_CONNECTION_UNAVAIL: 
        TextOut(hdc, 10, 10, "Connection unavailable.", 23); 
    //
    // Call an application-defined error handler.
    //
    default: 
        NetErrorHandler(hwnd, dwResult, (LPSTR)"WNetGetConnection"); 
        return FALSE; 
}
