Question

I want to get a list with all the threads (except the main, GUI thread) from within my application in order to do some action(s) with them. (set priority, kill, pause etc.)
How to do that?

Answer 1

You can use my TProcessInfo class:

var
  CurrentProcess : TProcessItem;
  Thread : TThreadItem;
begin
  CurrentProcess := ProcessInfo1.RunningProcesses.FindByID(GetCurrentProcessId);
  for Thread in CurrentProcess.Threads do
    Memo1.Lines.Add(Thread.ToString);
end;
