QUESTION
I've created a simple VBA interface to connect Excel to a MySQL DB. The VBA part acts as a preview of data for the user to choose what item he wants to import to the Excel sheet.
Until now I've work with a very complete set of data, but I got to a Table which (because of the nature of the items) some fields are NULL.
Now every time I try to check the values in the VBA I get the Run-time error 13 Type mismatch in the listview component. At first I though it was a field with DECIMAL typing, but after changing it to a DOUBLE (for testing) the problem persisted, and it was until I notice that if only checks columns with no NULL value, the problem disappears. Off course I can't omit this values.
I tried some .Tostring functions but with no success. And I failed to implement a IF to check for NULL in the obj.
This is my code:

QUESTION
I use the following code to update my widget's timeline, but the "result" which I fetched from the core data is not up-to-date.
My logic is when detecting the host app goes to background I call "WidgetCenter.shared.reloadAllTimelines()" and fetch the core data in the "getTimeline" function. After printing out the result, it is old data. Also I fetch the data with the same predicate under the .background, the data is up-to-date.
Also I show the date in the widget view body, when I close the host app, the date is refreshing. Means that the upper refreshing logic works fine. But just always get the old data.
Could someone help me out?

Answered 2021-Jun-15 at 17:05Update:
I added the following code to refresh the core data before I fetch. Everything work as expect.

QUESTION
I'm trying to understand how the "fetch" phase of the CPU pipeline interacts with memory.
Let's say I have these instructions:
...ANSWER
Answered 2021-Jun-15 at 16:34It varies between implementations, but generally, this is managed by the cache coherency protocol of the multiprocessor. In simplest terms, what happens is that when CPU1 writes to a memory location, that location will be invalidated in every other cache in the system. So that write will invalidate the line in CPU2's instruction cache as well as any (partially) decoded instructions in CPU2's uop cache (if it has such a thing). So when CPU2 goes to fetch/execute the next instruction, all those caches will miss and it will stall while things are refetched. Depending on the cache coherency protocol, that may involve waiting for the write to get to memory, or may fetch the modified data directly from CPU1's dcache, or things might go via some shared cache.

Answered 2021-Jun-15 at 14:01When you clone the element into the ul
(the same, but doesn't matter), give it the clicked
class with .addClass
at the same time.
You can then remove all the ".clicked" elements when you add your next entry.
