Hi guys, I'm not familiar with web programming, and there's one thing that interests me. for example, we have a web page somewhere at http://webpage.com/page

there's a text box and a button on the page. i input 2+2 in the text box and click the button. the result (4) is then displayed on a new page.

my question is: is it possible to write a small program (i.e. win32) that can submit 2+2 to the server and get the result?

thanks a lot

The LINK doesn't work, but is not a problem.

Yes, is possible, but you have to know an important thing:
How does your program comunicate with the server?
What protocol and service it uses (TCP, UDP,... HTTP, ecc.,..)


If you use the HTTP (throught TCP) you have to send requests to server via HTTP commands, like GET, and after recived the response from the server, your program should read the right data you want (for example, from an HTML web page response data)

For a faster program you can make your own server program that receves your data and responses only with the results you want.
Write a program that listen to 80h port (the server) and receves your special data and after it resends to your client program a TCP packet with only the result.


If you want some codes examples, tell me. (HTML code or PURE data)
