hiho@ll
i try to program a http proxy and i get in the client-requests a header Proxy-Connection: Close or Proxy-Connection: Keep-Alive
what does it mean?
i've not found anything in the RFC's and AFAIK it's something which was "born" from Netscape
but what exactly does it mean?
whats the definition for it?
anyone knows some resources?
thx@ll

Hello,
I have 3 HTML textbox controls with the same name & 3 button controls on the page. So it creates an array for textbox controls when I want to refer it in client Javascript. I want to hide one control at a time based on certain condition.
If I click 1st button, I want to hide 1st textbox. If I click 2ns button, I want to hide 2nd button & so on.
Can somebody help me in doing this?
Thanks
Hitesh

Thanks very much. It works.
Thanks again.

Hello People,
I'm trying to design some kind of windows form app. which I can also use as a plug-in in IE. just like Acrobat reader for instance. I'm a total newbie and I don't even know in which direction to think, so every comment is welcome. 
Thanks

i know that the tomcat server have the java runtime machine itself
is it right>?
it yes
how to increase its heap size?

i have just begun to learned jsp and java recently, so have the question below:
Situation:
My boss asked me to do a project for doing online data mining.
He requested the thing below:
1. Write a webpage by jsp with some textfield or pull down meun to get the parameter for getting the opinion and the parameter needed for the java class.
2. When the user click the buttom in the website, then the java class have to be invoked.
Questions:
1. ask i put the .java in the server, i can simply use cmd and type the following command:
java -Xmx800M P05context 1 1 3 6 F01xyz.txt F10xyz.txt
which F01xyz is the prepared text file for the java class to read and the F10xyz.txt is the output file generated by the P05context.class
but i don't know how to invoke the P05context.class by jsp
My boss have suggested me two ways to do this:
a. write a java virtual class to execute the java program.
but i don't know how to write.
i think conceptualy will be like this :
public class run_java<br />
{<br />
public void run java(parameter1,parameter2....,parameter6)<br />
{<br />
}<br />
}
b. write a javabean in the jsp. and i have try to use this code(at the end of the message:
but the tomcat server reply a internal error to me
how cani do ?

uuHai, I am doing a project on claculating the shortest distance between two cities. The problem is I do not have any idea on which programming language should I use. Is it possible for me to use Dreamweaver to create interface and ASP to calculate the distance? Or I need to use JAVA or C++ to do the find the shortest distance function? What is ASP actually? Is it a programming language like JAVA, Visual Basic?
Plz help me...I am really lost... HELP!HELP!HELP! Thanks!

Firstly, where do you get the data to do the calculations?

You could do this if you want.

ASP (active server pages) is basically a script that runs on a web server that returns HTML to the web user.
ASP is typically written in VBScript, although you can also use JScript.

How about just using the onmousedown event for the div? Here's a sample:
<html>
<body>
<div id="myDiv1" onmousedown="alert('myDiv1 mousedown');">This is myDiv1.</div>
<br /><br />
<div id="myDiv2" onmousedown="alert('myDiv2 mousedown');">This is myDiv2.</div>
</body>
</html>

Hi,
I have a file stored on the client machine which I need to capture and pass to a web service, preferably as a string. (currently using web service to get file, but this is on my local machine) How can I accomplish this using Javascript? If not js then any other suggestions or references?
Thanks in advance.

You cannot.
keepsmile wrote:

Depends on your application. One idea is that if your pages have a logical sequence then on each page load you store some sort of page sequence number in the Session object If the user pressed the back button and you detect the page loading a page out of sequence you can then redirect them to the correct page.
Does this help?

Strictly speaking, that isn't disabling the back button, it is replacing the history. Also, some people (and increasing number of people) have javascript turned off so your solution will not work for them.
You should realise however, that doing this will most likely irritate the users - they don't like it when web pages change the way they expect their browser to behave and I still recommend the solution I gave before as it does not change the browser behaviour. For instance if they press the back button to get off your web site.

I did this in ASP.NET a few months ago. I can't check the code because I'm at home, but I believe you have to open the file and after outputting the header, write the full contents of the file.
Check this thread on the ASP.NET to see how I did it:

return -1;<br />
}<br />
if ( (s = socket(PF_INET, SOCK_STREAM, 0 ) ) < 0) { <br />
perror("socket"); <br />
return -1;<br />
}<br />
sin.sin_family = PF_INET; <br />
sin.sin_port = htons(atoi(argv[2])); <br />
if ( (hptr = gethostbyname(argv[1]) ) == NULL){<br />
fprintf(stderr, "gethostname error: %s", argv[1]);<br />
return -1;<br />
}<br />
memcpy( &sin.sin_addr, hptr->h_addr, hptr->h_length);<br />
if (connect (s, (struct sockaddr *)&sin, sizeof(sin) ) < 0 ){<br />
perror("connect"); return -1; <br />
}<br />
if ( write(s, msg, strlen(msg) +1) < 0 ) { <br />
perror("write"); return -1; <br />
}<br />
if ( ( n = read(s, msg, sizeof(msg) ) ) <0) { <br />
perror("read"); return -1; <br />
}<br />
printf (" %d bytes: %s\n", n, msg); <br />
<br />
if (close(s) < 0) { <br />
perror("close"); <br />
return -1;<br />
}<br />
return 0;<br />
}<br />
I need the code for the request from the Client, and the response from the Server.
Please, help me ASAP... thanks to you in advance.
Please feel free to point out any errore in my code.

Hi all !!
I want to embed several MediaPlayer objects into the same page. I mean if I could play different mpg's at the same time in the same page. I've tried and the result is that the first MediaPlayer plays all of the mpgs at the same time (mixing all of them or somenthing like that) and the others remain as black boxes.
Is it possible to do?
