[Gambas-user] Empty While loop question

[nando]

Thank you.

VB has the same problem.
If I need to do pure processing of data for a extended period of time,
then while the code is running, the timer would never fire.

Question. Since this is the case, would the timer actually 
fire the timer event after an extended period of
processing data if the WAIT command happened much later in time 
after the actual delay of the timer was expired?

<code fragment>
...
Timer1.Delay = 1000
Timer1.Enable = True

WHILE processing_data=TRUE
  <process data - which takes a very long time>
WEND
...

PUBLIC Sub Timer1_Timer()
  TextBox1.Text = Current_time 'update time in a textbox
END
<end fragment>

...The time will never update and processing cannot be as fast as possible

I think it would be nice if the timer fired after the delay
regardless of what other code is doing.

Sincerely,
-Fernando
