Invalid charecters

Question

I need a validation message that when user send the invalid charectore as value to database invalid charectors thru send function a warning message is given that invalid values such as 'ABCD' charecter cannot be send.
Currently when invalid charecters are entered and send to server a message comes that all data is send, (even though invalid charecters are not really send).
How to ensure a warning message is given when invalid charecers are send to database.
Appreciate inputs.
Regards,

Hi,
you must write VBA code, something like this and put it in a module in a module (eventually adding boolean and if ok send data)
Sub Pulsante1_Click()
    checkChar ("sa°l")
End Sub
Function checkChar(in_put As String)
Dim charToExclude()
Dim i, j As Integer
charToExclude() = Array(",", "%", "/", "°", ".", "(", ")", ";", "!", "+", "^", "&", "", "?", "]", "[", "{", "}")
For i = 1 To Len(in_put)
    For j = 0 To UBound(charToExclude()) - 1
        If Mid(in_put, i, 1) = charToExclude(j) Then
            MsgBox Str(i) + " character cannot be send", vbCritical + vbOKOnly, "Error Message"
        End If
    Next j
Next i
End Function
Kind regards
