Listen Infinitely

[Errods]

How do I keep my application listening to a Port continuously.........

Can i implement a background thread with low prioity to do this or is there any other Way..............

well... you just set the winsock component to Listen. You shouldn't need to set anything else but you'd generally have code that triggers when data is received.

search for port, socket, listen as there have been plenty of posts about this.

once you got that part figured out, you will probably want write a windows service or set your application to run when the user logins

Will using winsock be efficent..............

 

[DiskJunky]

er... isn't that what you're using? If not, then yes, winsock is effecient if basic. Setting it to Listen tells it to set a hook and winsock will be notified by the os when data is received. It saves having to code a loop

Winsock is a COM component right.........

Say te listening part is done by a Windows service then can Winsock be used there..............

Thanks a Lot Man fo Your Guidance........

there isn't any reason why you *can't* use winsock in a service. After all, the IIS SMTP service for email is listening on port 25 for example. Just remember to close the port cleanly when your service is paused, stopped or cancelled.

Why use the old COM when you have .Net Framework support in System.Net.Sockets ?
Multithreading is a piece of cake, writing a loop as simple as keying "Do" (Enter).
Samples about TcpClient/TcpListener is what you should be looking at.
