如何在TextBox或MaskedTextBox限定用户只能录入金额数字？
先谢谢了啊~
[解决办法]
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
Try
If Char.IsDigit(e.KeyChar) Or e.KeyChar = ". " Or e.KeyChar = Chr(8) Then
If e.KeyChar = ". " And InStr(Me.Text, ". ") > 0 Then
e.Handled = True
Else
e.Handled = False
End If
Else
e.Handled = True
End If
Catch ex As Exception
End Try
End Sub

那就 maskedtextbox1（Mask:########）label1（text: ". "） maskedtextbox2（Mask:##）
然后取值 maskedtextbox1.text+ ". "+maskedtextbox2.text
