What have you done so far? The problem is very simple. Why text box?

Please, type of the application and UI library. There is more then one type called TextBox.
Also, use DateTimePicker instead.

Suggestion to all experts:

We should stop answering UI questions based on assumptions on the library to be used, as well as any other ambiguous questions. Some inquirers probably don't even suspect that there are at least three types named "TextBox". This is not an excuse. Answering based on assumption is not a good option, answering in more than one variant is not an option. We should wait until the inquirer eliminates the ambiguity.

In this case, I know the solutions which does not depend much on the UI library. I just don't want to make exclusions. The question mention a UI type which is specified with ambiguity. I just want to make this service more useful. It will be more useful if we insist on correct questions. In this way, we would devote more attention to the inquirers who deserve more attention.

Thank you for understanding.

Sample code change as per your requirement

bool m_flag = false;
DateTime dt = new DateTime(1983, 5, 1, 8, 30, 52);
        DateTime dt1 = DateTime.Now;
        string strDate = dt.ToString("M/dd/yyyy");
        string strDate1 = dt1.ToString("M/dd/yyyy");
        if (compareDates(Convert.ToDateTime(strDate1), Convert.ToDateTime(strDate)))
        {
            m_flag = true;
            Response.Write("Valid");
        }
        else
        {
            Response.Write("Invalid");
        }

<pre>public bool compareDates(DateTime dtHireDate, DateTime dtDateOfBirth)
    {
        int age = dtHireDate.Year - dtDateOfBirth.Year;
        if (dtHireDate.Month < dtDateOfBirth.Month || (dtHireDate.Month == dtDateOfBirth.Month && dtHireDate.Day < dtDateOfBirth.Day))
            age--;
        if (age >= 18)
        {
            m_flag = true;
        }
        else
        {
            m_flag = false;
        }
        return m_flag;
    }
