Visual Basic is one of those languages that are widely used but isn't at the top. Visual Basic (VB) is an event-driven programming language and the environment from Microsoft that provides a graphical user interface (GUI) that allows programmers to modify code by simply dragging and dropping objects and defining their behavior and appearance. VB is derived from the BASIC programming language and is considered to be event-driven and object-oriented. So it appears as though it's truly simple to learn and utilize this language, and it is. In numerous novice programming courses, understudies learn Python alongside Visual Basic. VB is a GUI-based advancement instrument that offers a quicker RAD (Rapid Application Development) than most other programming dialects. VB likewise includes a linguistic structure that is more direct than different dialects, a visual situation that is straightforward and high information based availability.
How Visual Basic is Used
The structure of VB is designed to allow programmers to use the environment to write executable files (exe files). The most mainstream kind of Visual Basic being used today is VBA. VBA is an adaptation of Visual Basic that can be utilized to program Microsoft Office applications, for example, Excel and PowerPoint. Typical users engage VBA to make repeated, everyday tasks less monotonous through the use of macros. Macros automate almost any activity—such as performing word and data processing or generating custom charts and tables. For example, a typical user might write a macro that allows them to create and fill a spreadsheet with a single click. Computer professionals use VBA and macros in more entangled manners. Developers will regularly compose macros that can reproduce enormous parts of code or characterize explicit dialects.
Advantages of Visual Basic
VB provides not only a programming language but an integrated development environment (IDE) that has been written and optimized to best support RAD. This permits software engineers to effortlessly construct GUIs and interface them to capacities inside the application. In Python, there is a module called PyQt5 that is utilized to create GUIs. Like Visual Basic, PyQt5 has fundamentally the same as utilization and sentence structure.
Windows 10 Activation after a Major Hardware Change
Categories: Tech | Pubby Cash Received: 10
Can windows 10 be activated after you do a major change to your hardware such as motherboard and hard drive? Why not? If it cannot be activated, it is a rip-off for Microsoft to charge you multiple times on the same computer. But it can be activated, what will happen if you migrate the license to multiple computers and that will make activating unlimited computers with one license purchase possible, and Microsoft will be losing money. This appears to be very confusing. We happen to experience such a dilemma when building two PCs: one with successful license migration, and the other failed. For our two cases, we were not doing a major hardware change on the original computer, we were building two completely new computers with an old computer with activated Windows 10 standby. The first build used the an M2 SSD with cloned hard drive data from the standby computer. Windows was activated on the spot while the standby computer was not affected. So, we had two activated computers with the same license. That was a saving of $120 - the cost of purchasing a new Windows 10 Home license. Our second build was done several weeks later. It was another completely new computer. Again, we used an M2 SSD with cloned hard drive data from the standby computer. The steps were followed exactly like our first build. However, there was no luck this time. Windows were not activated no matter how many times we repeated the process. The message on the Control Panel's activation page read something like "The license has been used". While reading a few articles on license migration after major hardware change, I understood the principle: the activated license info is printed in the motherboard. Upon a motherboard change, such info is definitely lost, and that's why you need to reactivate it. That's why we failed the second build. But how to explain our first build while the activation appeared to be carried over to the new computer automatically and we did not do any re-activation at all? I believe the trick was on the first login event with a same Microsoft account of the standby computer during the initialization of the first build. Microsoft detected the same login, which might trigger the re-activation automatically. However, if such change was done again in a short period of time (in our case, it was several weeks), it was not recognized as a regular major hardware change, because no one will upgrade a motherboard in several weeks, the license was marked as used and there was nothing you can do about it except purchasing a new license. This was our Windows 10 activation experience after many hours of tries. Obviously Microsoft will not tell you this, and you learn through your own tries. ... Read more

Underground Mega-Monument Found Near Stonehenge
Categories: General | Pubby Cash Received: 0
Scientists discovered holes near Stonehenge(a huge stone monument). This structure was built thousands of years ago in England. Nearby, scientists found many large holes that are underground. These archaeologists used special technology called ground-penetrating radar which uses radio waves. The archaeologists discovered 20 holes so far and they think the holes are part of a monument. Scientists do not know why Stonehenge was built while most think it had to do with religion. Vincent Gaffney is an archaeologist that helped discover the holes. He thinks the holes marked a dividing line that forms a circle surrounding the henge. The holes they've found shape an arc, not quite a full circle. Well, that is it for this article and I hope you learned something new.... Read more
Homemade Coronavirus Masks
Categories: General | Pubby Cash Received: 0
Several people wear masks when they leave their houses, due to the coronavirus. Wearing masks helps slow the spread of COVID-19 and two studies show which fabrics work best. Homemade masks can help block aerosols and some fabrics do this better than others. A team tested different fabrics and found two fabrics together worked best. The fabrics are cotton with silk or chiffon and the combination blocked most particles. It kept out nine out of 10 particles the team reported. The mask also needs to fit the face tightly as gaps can let virus particles in. They measured how many particles got through and the tighter fit helped so it kept more particles out. Wearing a mask protects you and also protects others.... Read more
