What statement causes a procedure to be executed in visual basic?

Answer 1

The basic code which responds to a specific event is called even procedure

OR

Event procedure is one which establishes the link between the object and code with the help of name

OR

Reaction og a control to the external condition

Answer 2

Firstly, a procedure in visual basic is a series of executable statements encapsulated between a declaration and a matching end statement. Procedures can be called by other procedures and return control to their calling procedure when completed.

The following are examples of possible procedures:

Sub

Function

Event Handling

Property Get/Set Procedures

Operator Procedures

Generic Procedures

Let's say that we want to be able to refer to a procedure by naming it as a subroutine, in this example one event procedure (Button1 Click) will call a second Sub procedure (CheckIfEqual).

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

CheckIfEqual()

End Sub

The above is how to correctly declare a Sub procedure and set it as an event handler, though visual studio will normally generate this code you automatically. You can see that when it is click, it will call and transfer control to another procedure named CheckIfEqual.

Private Sub CheckIfEqual()

If TextBox1.Text = TextBox2.Text then

MsgBox("They are both equal")

End If

End Sub

When the above is called it will check if two text boxes have equal text properties and display a message box to the user if true, it will then continue on and hit the End Sub line at which point it will return control to the calling procedure.

Hope this helps.

Answer 3

the term 'Sub' initiates the body.

and then, you may have noticed the mentioning of the name of the object after 'sub' and then the required event followed by a underscore.

Answer 4
