    Resolved [RESOLVED] CTRL+A - Select All: Beep sound?

    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

    Try setting KeyCode and Shift to 0 after calling your routine, as that will indicate that you have dealt with the key press.

    You need to handle the KeyPress event as well. It occurs in addition to the KeyDown and KeyUp events but allows you to cancel a key stroke by setting it's KeyAscii argument to 0.

    The KeyAscii value of a Ctrl+Letter key is from 1(A) to 26(Z)

    Code:
    Private Sub Form_KeyPress(KeyAscii As Integer)
        If TypeOf Me.ActiveControl Is VB.TextBox Then
            Select Case KeyAscii
                Case 3, 8, 22, 24 'Allowable control keys in a textbox ctrl-C, ctrl-H (backspace), ctrl-V, ctrl-X
                Case Is < 27
                    KeyAscii = 0
            End Select
        End If
    End Sub

    Yeah, I tried that first and didn't work.

            End Select
        End If
    End Sub
    Thanks. I just added the If KeyAscii < 27 part and it fixed it.

    Just to be sure you understand that without the Case 3,8,22,24 line the user won't be able to delete anything using the Backspace key nor do any Cut/Paste/Copy operations. Those keys will not cause a Beep because they are valid keystrokes in the TextBox.

    If that is allright then

    Hm, I had no idea about the 3, 22, or 24. Thanks.
