hi, this is my code when i click on the login button it will show process bar or connection bar until we get the response from the server over the internet...

please help me in this

that is what i want to do....>

anup123a at 2007-7-9 22:18:20 >

this example is taken from this link..

http://developers.sun.com/techtopics/mobility/midp/articles/midp2network/

this is a basic connection to a server...

...

SocketConnection client = (SocketConnection) Connector.open("socket://" + hostname + ":" + port);

// set application-specific options on the socket. Call setSocketOption to set other options

client.setSocketOption(DELAY, 0);

client.setSocketOption(KEEPALIVE, 0);

InputStream is = client.openInputStream();

OutputStream os = client.openOutputStream();

// send something to server or not

// depends on your application

os.write("some string".getBytes());

when the connection is established, you can display a new Form with a moving object

to tell to the user that the application loading the response...

// read server response

// display the "waiting form"

int c = 0;

while((c = is.read()) != -1) {

// do something with the response

//

}

// close streams and connection

is.close();

os.close();

client.close();

...

when the treatement is finished, you can display the result of the request

i hope that it will help you !
