What is Visual Basic? Visual Basic is a type-safe programming language that's designed to be easy to learn. What is Visual Studio? Visual Studio is an integrated development suite of productivity tools for developers.
Think of it as a program you can use to create programs and applications. What is a console app?
A console app takes input and displays output in a command-line window, a. What is. NET Core? NET Core is the evolutionary next step of the. Types of Arrays An array is a lot like a CD rack. You know: one of those rectangular boxes with slots to slide CDs in, each above another.
There are two types of Visual Basic arrays: fixed-size and dynamic. There are a limited number of slots you can slide CDs into.
To fit all of these in your rack, the rack must contain at least three slots. This is like numbering the slots on your CD rack starting at 0 up to 2 and then inserting a CD into each slot. Using Dim in a procedure will make the array only available from within that procedure.
Using it in the General Declarations section will make it available to all procedures in that module.
Private has the same effect and should be used only at the modular level. Using Public will make the array available throughout the project. ArrayName is the name of the array. Subscript is the dimensions of the array. DataType is any valid data type. You don't want to throw away any of your CDs to make room for the new one so you decide to use your ultimate building skills to attach another slot. Nothing wrong, you've just dimensioned your array another way that allows for expansion.
Notice that the subscript of the Dim statement is missing. Notice the Preserve keyword: it forces Visual Basic to retain all existing elements' values. Without this keyword all your old CDs would be lost and you'd be stuck with just Charlotte Church. Preserve is an optional keyword that forces Visual Basic to retain all existing elements' values. Without it all elements will return to their default values. Numeric data types to 0, variable-length strings to "" a zero-length string , fixed-length strings filled with zeros, and variants to empty.
The data type cannot be changed from its initial declaration when using the ReDim keyword.
The aim is to abstract the configuration necessary to piece together command line utilities in a cohesive unit, which theoretically reduces the time to learn a language, and increases developer productivity.
It is also thought that the tight integration of development tasks can further increase productivity. For example, code can be compiled while being written, providing instant feedback on syntax errors. While most modern IDEs are graphical. You use it to select which other IDE elements to view and to add forms or controls to your project. Toolbox The toolbox is simply a library of controls which you can place on your application.
Once you've placed all the controls you need onto your applications forms, you can hide the toolbox to make room for working in the other elements of the IDE. Project Window This is simply a list of all the forms which make up your VB project.
There are several kinds of forms. Property Window Such things as push-buttons, scrolling text boxes, pictures boxes and other features of most VB applications allow you to enter parameters which define how these controls work.
