Using HTTPRIO like Ajax

Hi,

I have,

procedure DoSomething;
var
    HTTPRIO: THTTPRIO;
    Res : TMyClass; // TRemotable
begin
   HTTPRIO := THTTPRIO.Create(AOwner);
   Res := (HTTPRIO as MyWebService).CallSomething;
   // Use Res
end;

1. Now when I call DoSomething the execution will not proceed until the DoSomething has finished. However, I wish it should proceed without waiting for DoSomething to finish.

2. Sometime it will also require to wait until DoSomething has finished.

I understand that this can be accomplished by using Threads. Can someone give me some example / working code for this?

My goal is to improve existing performance, can this approach be helpful? is there any risk with this approch?

Thanks.

In actual fact the Windows Socket interface is asynchronous, so one technically does not need threads. If you're interested check out the ICS Suite from Francois Piette (at Torry). But it's usage is not simple, although quite powerful.

The thread approach involves creating a class derived from TThread and overriding the procedure Execute. You simply put your app code in there.

You then create an instance of the thread (normally suspended) set any variables and then call Resume
