Sample codings to restrict special characters in vb6 & vb.net?
推荐答案
Option Explicit
'This will only accepts the alphabets and no other key is allowed.
Private Sub Text1_KeyPress(KeyAscii As Integer)
If Not KeyAscii >= 65 And KeyAscii < 90 Then
KeyAscii = 0
End If
End Sub
VB.NET:使用KeyPressed进行验证...
VB.NET: Use KeyPressed for validation...
''Textbox KeyPress
'' Allow number 0-9 plus backspace, Del + Home + End will be accepted also
Dim ValidInputChar = "0123456789." + vbBack
If not ValidInputChar.Contains(e.KeyChar) then
e.KeyChar=Nothing
End If
