VB Sample Code

Classic VB example:

Private Sub Command1_Click()
MsgBox "Hello, World"
End Sub

A VB.NET example:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Handles Button1.Click
MessageBox.Show("Hello, World")
End Sub

* Note that all procedure calls must be made with parentheses in VB.NET, whereas these were only required for function calls (however in VB6 they could be used in procedure calls as well by using the Call keyword)

* Also note that the names Command1 and Button1 are not obligatory. However, these are default names for a command button in VB6 and VB.NET respectively.

The following example demonstrates a difference between VB6 and VB.NET. Both examples unload the active window.

Classic VB Example:

Private Sub cmdClose_Click()
Unload Me
>End Sub

A VB.NET example:

Private Sub cmdClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Handles cmdClose.Click Me.Close()
End Sub
