Passing valus through the url

Hi,
i am trying to pass values to a struts action using javascript. It
works fine until the value has something like '+' or '&' sign in it.
Is this a problem with javascript or these values cannot be passed in
the URL ?

takeExample.do? field='+field+' &Code='+code

this is the url im making

if code is 'trying + something else'
i get 'trying something else' from the request.getPara meter

if it is 'trying & something else'
i get 'trying '
Please Help
Thnax in advance

They must be escaped. The ampersand (&) is used to separate name/value
pairs, and plus (+) can be used (but it's not the only way) to replace
spaces. Call encodeURICompon ent with the values you're going to add.
takeExample.do? field='+field+' &Code='+code


'takeExample.do ?field='
+ encodeURICompon ent(field) + '&Code='
+ encodeURICompon ent(code)

Unfortunately, encodeURICompon ent isn't implemented by older browsers.
However, you can emulate it:

if('function' != typeof encodeURICompon ent) {
this.encodeURIC omponent = function(uri) {
var x = /[\w.!~*'()-]/, r = '';
for(var c, i = 0, n = uri.length; i < n; ++i) {
if(x.test(c = uri.charAt(i))) {r += c;}
else {
c = uri.charCodeAt( i).toString(16) .toUpperCase();
r += ((c.length == 1) ? '%0' : '%') + c;
}
}
return r;
};
}

The code above will determine whether the function is implemented by the
browser. If not, a basic implementation[1] will be created.

[1] By "basic implementation" I'm referring to the fact that
encodeURICompon ent should be able to deal with Unicode characters. The
implementation above only concerns itself with the ISO-8859-1 (Latin)
character set.

I'm currently working on a small project (admitedly for my CS class) that compares the time difference between passing by value and passing by reference. I'm passing an array of 50000 int's. However, since in C++ an array is passed by reference by default I need to embed the array into a struct in order to pass it by value. The problem is that I get a segmentation error when doing so. I'm using the Dev-c++ compiler. Any ideas? ...

PARAFORMAT2 is a structure that SendMessage will return stuff in. Is the "ref" correct or since only a pointer is being passed should it be by value? Suppose I was passing data rather then receiving it, would that change the answer to the above?

I have these tiny classes, implementing an interface through which their method Render ( CosWriter writer ) ; is called. Given a specific context, there are potentially a lot of such objects, each requiring a call to that method to fulfill their purpose. There could be 200, there could be more than 1000. That is a lot of references passed around. It feels heavy. Let us say i changed the signature of the interface method to:

I was under the assumption that if you pass an object as a param to a method and inside that method this object is changed, the object will stay changed when returned from the method because the object is a reference type? my code is not proving that. I have a web project i created from a web service that is my object: public class ExcelService : SoapHttpClientProtocol {

Hello fellow C# programmers, This question is more about general practice and convention so here goes: I got into a discussion with a co-worker who insisted that as a general practice all objects should be passed by reference using the ref keyword generally speaking because as the writer of code you are conveying your intentions that an Object should/can be modified by your function.
