suppressing the freezing of application?

[Cenkovic]

Dear Delphi users,
I am a new user of Delphi and I apologize for my poor English. I have this problem. We have a measuring device which sends the data through the port to the computer. This measurement should be instant, so I think there should be an infinite loop in the program. For the reading data from the port we will have a DLL file, which its functions will assure this. My question is how to eliminate the freezing of the computer to have control of the application. I have tried the procedure Application.ProcessMessages and Application.OnIdle which does not work. Thank you for your advice. Tomas Cenkovic

in your measurement loop add this line :

var i : integer;

...
inc(i);
if i mod 1000 then Application.Processmessages
Sleep(20);
....


this will ensure that your app won't take 100% cpu time and leave time to other threads
