What is visual programming?
Visual programming is to create a computer program using image elements. The program is traditionally a sequence of text commands used to achieve a certain result or solve a problem. Programming languages often have special ways to represent the work to be done, leading to complexity. Visual programming is trying to make it easier to create programs. When the user enters a character, several suggestions are displayed directly below the text box. The visual program to achieve this goal would allow the programmer to place a range of boxes on the screen, one for each job and use the arrows to indicate the flow between the tasks.
The first field on the screen would indicate that waiting for the user's event. When the character is entered, the flow will be directed to a box that determines whether the character is valid. If the character is valid, the flow will be directed to the another box on the screen that searches the database.
pRohoping the database would have several partial tasks in itself. Clicking the database search box would cause a new screen that would show the programmer these sub -tasks and flow between them. Aspects such as stopping search when a fixed number of designs are found, or to give up search, if there are enough designs in a given amount of time, it would consider and deal with the programmer on this screen.
In addition to action and flow, the computer program has many aspects. This includes data relationships, data sharing with other programs, spreading work between sources and linking graphics for easy use. A set of text commands does not always solve all these actions in a smooth way, and for other programmers it may not be easy to understand all Implicacins. Visual programming attempts to solve most of these aspects.
There are many languages that allow programming visually. Visual programming languages usually include: Tersus for web applications, MVPL for robotics, LabView for scientists and synthmaker for sound tools. There are visual languages for programming manual and embedded computers. Visual C# or Visual Basic, however, are not visual languages. Although popular, they only allow you to locate items on the screen with which the user interacts.
Visual programming has been criticized for the production of programs similar to toys and the number of visual elements that can be displayed on the screen at the same time. The Deutsch limit suggests that about 50 elements can be displayed. Just as languages of the text have evolved, it is promising that visual languages can also solve these challenges.
