 |
|
I have an app where data is read from a serial device and is used to
populate controls on a Modal dialog. The serial data is read in a
thread to prevent the main app freezing but how do I wait until the
thread is finished before opening the dialog?. Is it OK to have:
start thread to read data
repeat
Application.ProcessMessages ;
until thread completed
Dialog.ShowModal
Is there a more elegant way? |

Hi!
I recommend using
Thread1.WaitFor
WaitFor doesn't return until the other thread terminates, either by
finishing its own Execute method or by terminating due to an
exception.
