joepezt,

I'm not sure if I get you right. If you just need quick way to extract channel
from list of strings with format "username=channel" then copy/paste this:


function UserChannel(list:TStringlist; user:String): String;
var s: String;
    i: Integer;
begin
   i:=list.IndexOf(user+'='); if i=-1 then Exit;
   s:=list.Strings[i];
   Result:=Copy(s, Pos('=',s)+1, Length(s));
end;

// DEMO:
//---------
procedure Tfrmmain.Button1Click(Sender: TObject);
var username: String;
begin
  username:='bla';
  Caption:='User: '+username+' is located in channel: '+UserChannel(frmmain.userlist, username);
end;


If this is not what you want, please be more detailed.

maybe...

function UserChannel(list:TStringlist; user:String): String;
var s: String;
   i: Integer;
begin
  result := list.strings.values[user];

//  i:=list.IndexOf(user+'='); if i=-1 then Exit;
//  s:=list.Strings[i];
//  Result:=Copy(s, Pos('=',s)+1, Length(s));
end;

i temporary solved this by doing:  

    if userlist.IndexOf(temp) = -1 then
    begin
      userlist.Add (temp);
      channellist.Add (channel);
    end;

but i would do nnot want to use 2 stringlists...

the problem is that if this list gets desynked, all channels nmight be out of synch with the userlist..
