macromedia flash flashcom: HI, I am building an app where I only want the person to access it unless
another user(admin) is already present. If not, I want it to go to a
particular frame in the movie that says "the person is not available".

I tried this using

application.onConnect = function(client ){
if (application.clients.length == 0){
var vError = new Object();
vError.message = false;
}

Then in the swf movie I put this

if (info.application.message == false){
gotoAndPlay("NotIn");
}

Now, of course I left the above 'if' statement out of the admin movie, but
this still connects the client to the movie even if the admin is not already
there. Any suggestions.

That's not really a great way to approach soemthing like this. You want to make
sure you have absolute control of who that admin is, so at very least you want
a password. Ideally, you'd want FMS to compare this to a database or secured
file on your https server, but for a quick and dirty job you can define the
password(s) in your ASC.

So, you might want something like this:

application.adminPwd = "somepassword";
application.adminIsIn = 0;
application.onConnect = function (client, clientType, pwd){
if (clientType == "admin" && pwd == application.adminPwd){
// It's the admin, set the adminIsIn variable
// IF the admin is already in, reject
if (application.adminIsIn == 1){
var err = new Object();err.message = "Admin Already In";
application.rejectConnection(client, err);
}else{
application.adminIsIn = 1;
client.clientType = "admin";
application.acceptConnection(client);
}
}else{
// It's not the admin. If the admin is in, accept the connection. If
not, reject.
if (application.adminIsIn == 1){
application.acceptConnection(client);
}else{
var err = new Object();err.message = "No Admin";
application.rejectConnection(client, err);
}
}
}

// When the admin leaves, we need to set that adminIsin var back to false
application.onDisconnect = function(client){
if (client.clienType == "admin"){
application.adminIsIn = 0;
}
}


Now, when you make your connection to FCS, you'll send some additional
parameters... like so

conn = new NetConnection();
conn.connect("rtmp://myserver/myapp/myinstance", "admin", "somepassword");

and

conn = new NetConnection();
conn.connect("rtmp://myserver/myapp/myinstance", "guest", "nopassword");
