ZEO and COM

drs
please let me know if there is a better place to post this ...

I am trying to create a shared dictionary which can be accessed via COM. To
that end, I have written the code below (at the end).

So far this works from a single computer, but if another computer tries to
share the data it is unable to see changes, and throws exceptions when it
tries to rewrite data.

Does anyone know how I can make all connections aware of changes?

Any ideas?

Thanks

This is w/ ZODB3 3.1.2, Python 2.2, win2k

Hello, I don't know if it is only me but I was sure that header("Location:url") redirects the browser instantly to URL, or at least stops the execution of the code. But appearantely it continues to execute the code until the browser send his reply to the header instruction. So an exit(); after each redirection won't hurt at all

I want viewers to compare state laws on a single subject. Imagine a three-column table with a drop-down box on the top. A viewer selects a state from the list, and that state's text fills the column below. The viewer can select states from the drop down lists above the other two columns as well. If the viewer selects only one, only one column fills. If the viewer selects two states, two columns fill. Etc. I could, if appropriate, have...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
