Detecting Enter keypress on VB.NET

Question

In the KeyDown Event:

 If e.KeyCode = Keys.Enter Then
       Messagebox.Show("Enter key pressed")
 end if

Make sure the form KeyPreview property is set to true.

Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
    If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
        SendKeys.Send("{TAB}")
        e.Handled = True
    End If

End Sub

There is no need to set the KeyPreview Property to True. Just add the following function.

Protected Overrides Function ProcessCmdKey(ByRef msg As System.Windows.Forms.Message, _
                                           ByVal keyData As System.Windows.Forms.Keys) _
                                           As Boolean

    If msg.WParam.ToInt32() = CInt(Keys.Enter) Then
        SendKeys.Send("{Tab}")
        Return True
    End If
    Return MyBase.ProcessCmdKey(msg, keyData)
End Function

Now, when you press Enter on a TextBox, the control moves to the next control.

I'm using VB 2010 .NET 4.0 and use the following:

Private Sub tbSecurity_KeyPress(sender As System.Object, e As System.EventArgs) Handles tbSecurity.KeyPress
    Dim tmp As System.Windows.Forms.KeyPressEventArgs = e
    If tmp.KeyChar = ChrW(Keys.Enter) Then
        MessageBox.Show("Enter key")
    Else
        MessageBox.Show(tmp.KeyChar)
    End If

End Sub

Works like a charm!
