I am having a problem with a page that creates a treeview from a database,
by reloading itself on each request for a new folder to be explored.
The problem revolves around using an array to store the data, that is
copied to a session variable, and reloaded from that with each new view.
That is, on first opening the page, the array is created and populated,
then copied over; subsequent reloads of the page load the session variable,
rather than create the array. This is where the problem lies - by DIMing
the array, the first load of the page is fine, but a type mismatch pops up
when the session is pulled in to the array name; not DIMing the array, the
first load fails due to not declaring the array.
Currently the ony way I have round the problem is to switch option explicit
off and not DIM any variable. If there was a way to have the session
variable and array co-exist to start with, that would be good.
TIA

I always bring arrays local before referencing them. This might help a
little bit (though not directly related): http://www.aspfaq.com/2524

I've got a type mismatch error that's driving me nutty. Variable blnNoData
has the initial value False. If a recordset comes back empty (both .EOF and
..BOF are true) then blnNoData is set to True. I then have an if statement to
determine what to write to the screen depending on blnNoData. As long as the
if statement is true (doesn't have to go to the else clause), the code runs
fine. Otherwise, a type mismatch error is returned. In...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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,...
