I have a VERY LARGE pile of geographic data that I am importing into a database (db of choice is postgres,
though may hop to oracle if necessary). The data is strictly hierarchical - each node has one, and only one
parent. The depth should not exceed 6 or 7 levels. The initial import will have about 6 million leaves, and
3 million branches. I would expect the leaves to grow significantly, in number easily tripling. However, the
branches will...

I'm implementing a folder browser style control in a tree view.
Windows Explorer, when it comes up with a tree view, almost immediately,
knows if folders contain other folders or not (unless it's a networked
drive).
How does it accomplish this? Obviously doing Directory.GetDirectories() for
each subdirectory is not going to give me that sort of immediate response.

I have a binary tree in VB NET and insertions seem to be slow.
The program receives data from one source and inserts it into the tree.
The program receives data from another source and looks the data up in the
tree.

Problem with mapping a directory tree to a tree control: It takes a
while to recurse subdirs and map them to nodes. This is solved in
some books I've seen (MacDonald, Albahari) by reading the subdir only
when its node on the tree control is opened.
Has anyone pre-packaged this functionality into a control?

I would like to 'grab' certain directory trees and then store them in a
table.
At the moment, I writing my own VBA to do this but I cannot help
thinking that there must already be something (i.e. plug-ins or snippet
of code) around that can do this. Can anyone advise me on this?
And what is the most efficient/flexible way to store directory trees?
At the moment I am planning to drop the directory tree into the

I have been using EzTwain Pro to scan documents into my access program.

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:

Overview:
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,...
