Editor’s note: Revue was acquired in 2021 by Twitter and is now being closed. Another Elon-troubled?
It’s been tougher than usual, mainly because of a copyright issue: the first name I had given the app was not accepted by Microsoft, because it recalled (even if only in part) one of their products.
Now my app is in the Microsoft Store, installable with a 30-day trial period (payment is made at the end of the period, if you wish to continue using it).
The goal of this app is to provide various productivity and utility tools for a secretary’s office, a small office, a clinic…in short, whatever you want (also for home and personal use).
Currently there are two modules: a professional word processor and a professional spreadsheet.
Later there will be tools such as: a pocket calculator (I’m already working on that), a notepad for notes, a contact management, a “to do list,” appointment management, a simple “protocol” for incoming and outgoing mail, a PDF reader (maybe even for editing them, we’ll see), a QRcode generator and reader, and much more… An all-in-one product for all your office management needs!
Visual Studio Installer was recently modified, adding the ability to start upgrading multiple editions of Visual Studio.
For example, I have four editions installed: VS Enterprise 2017, VS Community 2019, VS Community 2022, and VS Enterprise 2022 Preview.
Today there are two upgrades available (Community 2019 and Community 2022): in the past I would have to upgrade one edition, wait for the installation to finish and then start the other upgrade.
Now, however, you can click on the “Update All” button that appears when there are at least two updates available and everything will be done without the need to man the machine.
Select the menu item Tools > Create GUID: this will open a window like the one you can see in Figure 1.1.
Figura 1.1 – Create GUID window.
You can choose one of six available formats and then copy the GUID code by clicking on the Copy button, or you can generate a new GUID code by clicking on the New GUID button.
This is a useful feature when you need to create a GUID code “on the fly.”
NOTE – It is not advisable to use a GUID for cryptographic purposes because it consists of only 122 bits with a partially predictable bit pattern. Some cryptographic components have criteria that require a minimum 128-bit entropy level.
If you need to create a set of GUID codes, then the following code will be useful:
C# - Esempio CS_01_01
// Crea e visualizza il valore di due GUID
Guid g = Guid.NewGuid();
/* Questo esempio di codice produce un risultato simile a questo:
VB - Esempio VB_01_01
Dim g As Guid = Guid.NewGuid()
Problem with VISUAL STUDIO INSTALLER looping while checking for updates does not finish.
There is a problem confirmed by Microsoft on repositories outside the US.
Open Notepad as administrator and look for the file “hosts” without extension in C:\Windows\System32\drivers\etc
Open the file and add this line:
to the end of the file
Then save the file, close the Visual Studio Installer and restart.
It should be fixed.
UPDATE: Microsoft has solved this problem.
Final version of the book “PROGRAMMING IN C# 10 – Base Techniques”, in PDF version:
Within two weeks also the paper and EPUB versions will be available on Amazon Store and other online stores.
I’ve published the (almost) final version of the book “PROGRAMMING IN C#10 – Basic Tecniques” … the only thing missing is the update of the analytical index at the end of the book.
Soon the final PDF publication and then in a couple of weeks also the paper version!
I have published the 15th chapter of my book “PROGRAMMING IN C# 10 – Basic Techniques” (out of 20 total chapters, so far 236 pages out of about 360 total). Perfectly on schedule!
I have published the first 11 chapters of the book “PROGRAMMING IN C# 10 – Basic Techniques”. Upon completion, the book will consist of 20 chapters. Publication of the final paper version should be between late April and first half of May 2022.
I finished the English translation of my book on MS Word (specifically the one included with Office 365). Here is the PDF version, at a reduced price for a few days/weeks:
In a few days there will also be the paper version on all major online stores (Amazon, IBS etc.).
The book is (should become…) the first book of my new “series” of computer science manuals in English, so it’s a test to see if it can work.
