Re: [perl-win32-gui-users] Avoid the appearance of a "frozen"

[Perl R. <pe...@co...>]

Thanks for all the great responses! I changed my code so that each GUI
handle is managed only by the thread that created it. This works
perfect--and has eliminated all the crasing I was seeing!

As a follow-up question, how do you know *for sure* which modules are not
thread-safe? For example, I wouldn't have guessed that DBI isn't thread
safe.

Thanks again,
Rob

To clarify my earlier comment:  DBI is considered threadsafe but some  
of the DBD's are not.

Here's more info:

As far determining which modules are or are not threadsafe, read the perldocs!

Thanks,
Charles Alderman

Re: [perl-win32-gui-users] Avoid the appearance of a "frozen"

[Octavian R. <ora...@gm...>]

Thread safe or not, unlike a Win32::GUI object, a $dbh object can't be 
shared among more threads.
Does anyone know why? Because of DBI, of DBD::mysql, or because a database 
connection can't be shared among more threads, or something else?
