associate physical and logical drives

by: chris6995 |last post by:

I'm looking for a way to programatically query for the association between a physical device (i.e. removable USB storage) and it's logical drive letter. I've gone through Win32_LogicalDisk, Win32_DiskDrive, Win32_PhysicalMedia in system.management... I've also run through WM_DEVICECHANGE and the device types under DEV_BROADCAST_HDR. I can't find anything that gives me the logical drive letter mapping for physical device/drive - in this...

Physical vs Logical My Documents question

by: dgk |last post by:

Is there some built in way to know whether a physical folder path is 'My Documents" for a specific user? I can always use xxx.StartsWith to compare it to the enumeration returned by the Personal folder, but it seems a bit inelegant.

DAL is physical mapping and BLL logical?

by: MattM |last post by:

Looking at a tutorial for Asp.Net 2.0 using Northwind, the DAL was built by dragging the tables on to an XSN to create a dataTable object for each table in the database. The BLL was then mapped for each entity but since the data was simple it mapped to a physical table (ex. customer). But what do you do if your tables don't match up the physical and logical? For example, you could have a table for people, a table for job codes, and a...

Problem With Comparison Operator <=> in G++

by: Oralloy |last post by:

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 Here is the code in...

The easy way to turn off automatic updates for Windows 10/11

by: Hystou |last post by:

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,...

AI Job Threat for Devs

by: agi2029 |last post by:

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
