New ASync Demo

ASync Processing Demo - Features to Watch for

1. Process using a dedicated background thread. This is the same technique shown on March 10th. (Leave all checkboxes blank.)
2. Inform the surfer:
   • Using META REFRESH and redrawing status information (shown March 10th)
   • By keeping the connection open and using JavaScript to update a status field- requires RUNISA.DLL dated April 2, 1999.
3. Flow of control
   • Surfer can cancel the process
   • Surfer can read other pages during processing
4. Process using a globally shared background thread. (Check the last checkbox; recommended for high traffic)
5. Process in N dedicated threads (Uncheck the last checkbox.)
6. Process the work over multiple executions to provide a percent-complete interface. (Check the "Process work over multiple executions" option.)

   function TThreadInput.SendUpdate(PercentComplete:integer):Boolean;
   var
     a1:string;
   begin
     Result:=True;
     if bStreaming
     and assigned(Stream) then
       with Stream do begin
   
     if temp<>stream.name then begin
       sleep(100);
       temp:=stream.name; 
       end;
   
         a1:=chForEach; // chunk-for-each
         StringRepl(a1,'XXX',inttostr(PercentComplete));
         if not SendBufferToMailBox(Name,'+',pchar(a1),length(a1)) then begin
           Result:=not bAbort;
           end;
         end;
   end;
