[Zope] threading cont ...
First, thanks to Dieter :) Well, I have written a simple test products, which I have attached to this message as a .tgz file. This product does vert little things. When B1 is pressed, two new threads will start, one will update column of the database table, while the other will prompt the current time. When B2 is pressed, all threads will terminate. When B3 is pressed, it will show the database table. For this product, I used the SybaseDAv2 to connect to the local Sybase 11.9.2. The problem is, I can always see the results by pressing B3. However, when I looked into the database using isql, nothing has ever changed :( What's wrong? I really have no clue. Please kindly help.
