OK, many thanks Michael.
Hum, i have a dynamic array of threads.
mythread.create has :
FreeOnTerminate := True;
So, when the thread terminate, it frees the memory too ? (yes/no).
And it explain why i get a crash and error message if i try to do, for dynamic
arrays of threads :
> if length(MyArray) > 0 then
> for x := 0 to high(MyArray) do
> MyArray[x].Free;
Because the threads are already freed (yes/no) ?
If so, how can i know if MyArray[x] was already freed ?
When i use:
if assigned(MyArray[x]) then MyArray[x].Free;
It does not work.
Many thanks.
Fred
