I remember that when I first came into contact with VB, I didn't know how it was used. But when I learned how to drag the control to the dialog box, I was addicted to it. This drag-and-drop programming method has gone deep into my heart. The main reason for using programming software is to drag and drop. After a long time, I found that I did not do anything. Indeed, the drag and drop of the control allows users to quickly see the results, but it is like a mirage. It looks gorgeous, but it is still far away from reality. What's worse, it makes the first-time users cool and loses the patience to read the code.
I didn't do anything before I got started with visual programming, and I didn't do anything after I got started with visual programming. Visual Programming does not play a key role for users. But when you don't need it, it may help you a little bit. The role of visual programming is minimal. The main part of the program is code. The drag-and-drop control takes less than % 0 in the programming cycle. 0000 ....... 1. Although we only see controls, do not be fooled by them.
