What are events in VB?
An event is a signal that informs an application that something important has occurred. For example, when a user clicks a control on a form, the form can raise a Click event and call a procedure that handles the event. Events also allow separate tasks to communicate.
What is main procedure?
A main procedure is a procedure that can be specified as the program entry procedure (and so receive control when an ILE program is first called).
What is function in VB net?
In VB.NET, the function is a separate group of codes that are used to perform a specific task when the defined function is called in a program. After the execution of a function, control transfer to the main() method for further execution. It returns a value.
What is the difference between function and procedure in VB?
A procedure is compiled once and can be called multiple times without being compiled. A function returns a value and control to calling function or code. A procedure returns the control but not any value to calling function or code.
Is void a function?
Void functions are created and used just like value-returning functions except they do not return a value after the function executes. In lieu of a data type, void functions use the keyword “void.” A void function performs a task, and then control returns back to the caller–but, it does not return a value.
What is sub in VB?
A Sub procedure is a series of Visual Basic statements enclosed by the Sub and End Sub statements. The Sub procedure performs a task and then returns control to the calling code, but it does not return a value to the calling code. … You can define a Sub procedure in modules, classes, and structures.

What is parameter in VB net?
A parameter represents a value that the procedure expects you to pass when you call it. … For each parameter, you specify a name, a data type, and a passing mechanism (ByVal or ByRef). You can also indicate that a parameter is optional. This means that the calling code does not have to pass a value for it.
What is private sub in VB?
Private Sub sets the scope so that subs in outside modules cannot call that particular subroutine. This means that a sub in Module 1 could not use the Call method to initiate a Private Sub in Module 2. ( Note: If you start at the Application level, you can use Run to override this rule and access a Private Sub)
How do you call a function in Visual Basic?

What is a function and procedure?
A procedure performs a task, whereas a function produces information. Functions differ from procedures in that functions return values, unlike procedures which do not. However, parameters can be passed to both procedures and functions. In a program for drawing shapes, the program could ask the user what shape to draw.
How do you sum in Visual Basic?
