(This could potentially be a very exciting new series -- I am optimistic enough about this idea that I suffixed the title with a #1!)
One of the things I like about this blog is that people often point me at things that I might never have known about otherwise....
Like earlier today, when over in the Suggestion Box, Frederic Delhoume asked:
I have been unable to find any information related to locale aware memory formatting.
I use StrFormatByteSize but how does it get its formatting information ?
I have not found any Win32 API related to this topic.
This function is a fascinating bit of code, in both good and bad ways.
Here is how it works:
So you end up with a string that is partially formatted based on the default user locale and partially formatted based on the default user UI language.
In my opinion the same setting could (perhaps should?) be used throughout.
But even more importantly, a function should take the locale/locales to use and then perhaps a simpler version could pre-fill the information for the Shell usage.
With the current code, any other settings are inaccessible, which does close down a whole bunch of scenarios.
This could be an interesting feature to consider adding to a GetNumberFormat/GetNumberFormatEx extension or new function that could take the info about units to use. I see lots of interesting complications that may not make it practical, but I think given the extensive work behind StrFormatByteSize, there is clearly a scenario worth thinking about....

Is there also a bug in it determining its formatting behavior by looking to see if the number is between 1 and 1000? I'm not quite getting what that step is doing there.

That is not so much a bug as just making sure that they will have a compact little number to use. It helps them determine whether to have anything in a decimal place or go for whole numbers....

Couldn't you just show us the sourcecode =) Thanks for the explanation!

"So you end up with a string that is partially formatted based on the default user locale and partially formatted based on the default user UI language."
My old topic: which should also happen for currency formatting :-) (and adding an extra level, the currency itself)
- use a user-provided currency
- use the UI locale for currency translation
- use user locale for number formatting and currency positioning
