Is there a way to get rid of that beep sound when using CTRL+A to select all text in a textbox?

I'm using this code, with the Form's KeyPreview property set to True.

vb Code:
  1. Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
  2.    
  3.     If Shift = vbCtrlMask Then
  4.        
  5.         If KeyCode = vbKeyA Then
  6.             Control_SelectAll Me.ActiveControl
  7.         End If
  8.    
  9.     End If
  10.    
  11. End Sub
  12.  
  13. Public Sub Control_SelectAll(ByRef ControlObject As Control)
  14.    
  15.     On Error Resume Next
  16.    
  17.     With ControlObject
  18.         .SetFocus
  19.         .SelStart = 0
  20.         .SelLength = Len(.Text)
  21.     End With
  22.    
  23. End Sub
