关于验证

    /*----------------------
     *
     * 使用方法
     *
    1) 建立新窗口
    2) 使用VadTextBox
    3) 设置属性：
            vadTextBox1.VadFormat = VadString.DateTime("-", " ", ":");
            vadTextBox1.MatchStart = true;
            vadTextBox1.MatchStop = true;
            vadTextBox1.ErrorInfo = " Try Again";
    4) 添加普通按钮
    5) click 事件
            foreach (Control control in this.Controls)
            {
                // Set focus on control
                control.Focus();
                // Validate causes the control's Validating event to be fired,
                // if CausesValidation is True
                if (!Validate())
                {
                    DialogResult = DialogResult.None;
                    return;
                }
            }
