Substrings and indexes

Question

I'm creating a Mobile website using J2me, ASP and WML.

I read from a DB and created a string as the following so I can later call it.

                string id = reader[0].ToString();
                string name = reader[1].ToString();
                Response.Write("#" + name + id);

in J2me I recall it as

stringItem3.setText("Welcome  "+result.substring(result.indexOf("#")+1)
  + "ID " + result.substring(result.indexOf("#")+2));

and the results are not as I wanted I tried to change a lot with the syntax but with no luck.

the results always show as

enter image description here

while what I really want to show is something like

Welcome  (name)  ID : (id)
or
Welcome  Arin  ID : 20111

What is the best way to get the right results?

And can I later save the id value in a string inside J2me to use it later (yes/No)?

I changed the string (solved)

string id = reader[0].ToString();
string name = reader[1].ToString();
Response.Write("*"+ id + "#" + name);

and when getting the info

stringItem3.setText("Welcome  "+result.substring(result.indexOf("#")+1)
  + "ID " + result.substring(result.indexOf("*")+1,result.indexOf("#")));

result.substring(result.indexOf("*")+1,result.indexOf("#")));

which is mean to get the chars between "*" and the "#"

now the results are fine as below fig.

The string you're saving looks like #Arin20111, so indexOf("#")+2 is the 2^nd character after the #.

So result.substring(result.indexOf("#")+1) is the entire string after the #, which is the name and ID. And result.substring(result.indexOf("#")+1) is the same string except for the A at the beginning.

If you know the name will never contain a #, you might store the string as #Arin#20111. Then the name is everything after the st#and before the 2nd#, and the ID is everything after the 2nd#`.
