Stop Statement (VB.NET)

VB.Net > Statements > Stop

Stop is a programmatic alternative to setting a breakpoint and suspends the execution. When the debugger finds Stop statement, it breaks execution of the program.

Note: Unlike End, it does not close any files or clear any variables.

Example:

Dim i As Integer

Dim j As Integer
For i = 1 To 100
 j = i + 1
 Stop
Next i

With...End With Statement (VB.NET)

VB.NET > Statements > With...End With

Executes a series of statements that repeatedly refers to a single object or structure.

Example:

Public Class Form1

  Private Class Customer

    Public Property Id As String

    Public Property Name As String

  End Class

  Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    With New Customer

      .Id = 1

      .Name = "Elsoft"

      MessageBox.Show(.Name)

    End With

  End Sub
