The typeof operator returns an instance of System.Type corresponding to the class name you passed it to. You can't determine the type of an object using the typeof operator. For example class Foo{} class Test { public static void Main(string []args) { Console.WriteLine(typeof(Foo)); //Prints Foo Foo f = new Foo(); Console.WriteLine(typeof(Foo)); //Does NOT work. } } The GetType function gets you the runtime type of an object. Note that it is the *runtime* type and not the static type. For eg. public void SomeFunc() { object obj = new Foo(); Console.WriteLine(obj.GetType()); } will print Foo and not Object. The is operator checks the runtime type of the arguments and sees if the LHS is (or can be cast to) the RHS. It returns true if the casting can succeed and false otherwise. For eg public void SomeFunc() { Foo f = new Foo(); Console.WriteLine(f is Foo); //Prints true. object obj = new Foo(); Console.WriteLine(obj is Foo); //Prints true object obj2 = new object(); Console.WriteLine(obj2 is Foo); //Prints false } Hope this helps.

you have to make your function that will check for existance of Machine in Network you can these api to enumerate the Machine on network:- Use WNetOpenEnum to Open Handle then do Enumertation by WNetEnumResource finally close it by WNetCloseEnum "I Think this Will Help" [Vote One Here,.....] visit me at http://www.thisisalok.tk

Hi Thanks but the function IsNetworkAlive() works only for TCP/IP connection, but my machine can be on IPX/SPX isn't there any generic function call which could tell me if my machine is on any type of LAN.

FTP has very little capability built into it. You won't be able to execute anything other than a file transfer or directory listing using it. You'll need to write a proc on the server to save a snapshot out of the database to a file. Then you'll need to write a set of code that does a put to the FTP site. If you are looking to code part of this in .net you can look into the FTP library from edt http://www.enterprisedt.com/downloads/csftp/csftp.html[^] Hope that at least points you in the right direction.
