Windows Image Acquisition from managed C++?

by: Ryan Melville | last post by:

Hi, I need to use WIA (Windows Image Acquisition) from managed C++. Is there a "new and improved" way to access WIA from managed C++ (i.e., through .net)? Or, is it the same COM calls as from unmanaged C++? If it's the same COM calls, is there a "new and improved" way to access COM through managed C++? Or, do I do the same CComPtr magic as with unmanaged C++? Or, can I not use ATL facilities from managed C++ and I would have to...

Help Create Good Data Model

by: mwt | last post by:

Hi. I'm reworking a little app I wrote, in order to separate the data from the UI. As a start, I wanted to create a iron-clad data recepticle that will hold all the important values, and stand up to being queried by various sources, perhaps concurrently. In all likelihood, the app will never need anything that robust, but I want to learn to write it anyway, as an exercise. So here is my code. It's really simple, and I'm sure you can see my...

So before I program this up completely manually again, I thought I'd ask for better ways to think through this problem. We have several client machines, and a central data warehousing server. Each machine may contain hundreds of surveys, and they all are sent to the central server. Only they can never be networked together, forcing us to use files. I...

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 "<=>".

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,...
