I used FindFirstUrlCacheEntry/FindNextUrlCacheEntry Win API to get Internet Explorer's history programmatically in C++.
Can you tell me how to get Microsoft Edge History using C++ (Windows API)?
Not possible at this point in time. Might want to use the 'suggestions routes' at some of the links below.

The history is stored in \AppData\Local\Microsoft\Windows\WebCache\WebCacheV01.dat. It uses Microsoft’s Extensible Storage Engine to store data. There is a C++ wrapper for accessing Extensible Storage Engine files I've used to access data from this file.
The "Containers" table inside WebCacheV01.dat tells which "Container_X" tables have type of "Content" or "History", as well as the Secure Directories and their order. You can use the ESEDatabaseView utility to view the data inside the WebCacheV01.dat file.

My ultimate goal is to have map data (offline, because I will customize it myself) and display it in an app (Android). I could make osmdroid work to load maps online and I was trying to figure out how to download and display offline maps. I downloaded MOBAC (Mobile Atlas Creator) and export the data to SQLite format and when I had a look at it I realized that tiles are saved in image format (PNG).
What I would like to do is to import data to the phone to later use it in algorithms such as a search engine or a routing algorithm, so I need the "nodes" and "ways" (as I get them from the original OSM XML), import them to the phone and visualize it to later have this data available for the algorithms I want to develop. Basically, what MAPS.ME does. I think it wouldn't be difficult to convert the XML into the SQLite since a simple script could make it, but then, how can I generate the tiles from this custom SQLite database? Or, is there a way I can download the data in a more appropriate way to do what I'm planning to do?
Thanks.
Rendering the tiles in an app from raw Openstreetmap data would be computation heavy and inefficient. I would suggest to use image tiles you exported for visual representation.
In addition to tiles you should export a data set you will need in the application for desired functionality. You will not need all data from Openstreetmap so you should identify what you need and build your custom export (there are tools and libraries for processing and filtering of Openstreetmap data. I have used pyosmium for some filtering and processing but there are others.) For example, you can build your custom database with POIs you want to search for.
Routing is another chapter. You can implement it yourself but it is a very complex task. There is java library called Graphopper which can do the data extraction (from Openstreetmap) and offline routing for you. They have an online API too but it is possible to make it working completely offline (I did it for one application). Try to look at the source code because than you can see how complex topic routing is. Final note: data exported from Graphopper contains information about some POIs along routes. It may be possible to search for some things via its java API but I haven't investigated this yet.
I need some help for interrogating an xlsb database (file) from a VCL C++ program; (using C++Builder XE2) mainly, i would like to query the data inside for simple viewing (its on the same machine, no networking involved), and i don't need to modify it ! so i would like to know :
Which control to use for connecting to an xlsb database
(TDatabase, dbExpress ?)
How to use that control for the purpose
of reading the data, (same as SQL?)
The difference between the regular xsl and xslb, and are they used in the same manner ?
I did some research before asking, but the information about that is pretty scarce !
(i'm on Win 7 64bit)
Thank you all !
Never tested it with these files but i believe you can use a TADOConnection and then user Microsoft OLE DB Provider for ODBC Drivers as the data provider, i know it can use access and excel files as a source, personally i have only ever used it for access files, but it might do what you want.
We have a proprietary file format which has embedded in it a product-code.
I am just starting down the path of "enabling the end-user to sort / filter by product-code when opening a file".
The simplest approach for us might be to simply have another drop-down in our customized Open File Dialog in which to choose a product-code to filter by.
However, I think it might be more useful to the end-user if we could present this information as a column in the details view for this file type - just as name, date-modified, type, size, etc., are also detail properties of a file-type (or perhaps generic to all files).
My vague understanding is that XP and prior Windows OSes embedded some sort of meta data like this in an alternate data stream in NTFS. However, Starting in Vista Microsoft stopped using alternate data streams due to their dependence upon NTFS, and hence fragility (i.e. can't send via file attachment, can't move to a FAT formatted thumb drive, etc.)
Things I need to know but haven't figured out yet:
Is it possible / Is it practicable / how to create a custom extended file property for our file type that expresses the product-code to the Windows shell so that it can be seen in Windows Explorer (and hence File dialogs)?
If that is doable, then how to configure things so that the product-code column is displayed by default for folders containing our file type.
Can anyone point me to a good starting point on the above? We certainly don't have to accomplish this by publishing a custom extended file property - but that seems like a sensible approach, in absence of any way to measure the costs of going this route.
If you have sensible alternative approaches to the problem, I'd be interested in those as well!
Just found: http://www.codeproject.com/Articles/830/The-Complete-Idiot-s-Guide-to-Writing-Shell-Extens
CRAP! It seems I'm very late to the banquet, and MS has already removed this functionality from their shell: http://xpwasmyidea.blogspot.com/2009/10/evil-conspiracy-behind-customizable.html
By far the easiest approach to developing a shell extension is to use a library made for the purpose.
I can recommend EZShellExtension because I have used it in the past to add columns and thumbnails/preview for a custom file format for our company.
What is the best way to store application configuration in a Qt application?
If You store only list of name-value pairs QSettings class will suffice. It is cross platform and works well.
Check this page for more info:
http://doc.qt.io/archives/qt-4.7/qsettings.html
On the other hand if You have to store data in multiple tables (many params, many rows) I suggest You use Sqlite and QtSQL. Sqlite is ralational database that can be embeded in your application without the need of starting any servers or installing additional software. Sqlite sotres all tables in one *.db file. You can place each user's configuration in his home directory.
This link demonstrates how QtSQL library works:
http://doc.qt.io/archives/qt-4.7/sql-sqlstatements.html
Well, as you're using Qt anyway, why not using QSettings? You can use its default settings to save your configuration in platform specific default locations (e.g. Registry under Windows) or use it to write to classic INI files.
