      Dim info As New System.Globalization.CultureInfo("en-US", false)
        Dim cal As System.Globalization.Calendar
      cal = info.Calendar

      Dim myDateTime As New System.DateTime(1979, 7, 28, 22, 35, _
                                            5, 15, cal)

      ' Write the DateTime as "Saturday, July 28, 1979 10:35:05 PM".
      System.Console.WriteLine("{0:F}", myDateTime)

            // Create a new instance of DateTime containing the date 
            // 7/28/1979 at 10:35:05 PM using the en-US calendar.
            System.Globalization.CultureInfo info =
                new System.Globalization.CultureInfo("en-US", false);
            
            System.Globalization.Calendar calendar = info.Calendar;
                
            System.DateTime dateTime = 
                new System.DateTime(1979,        // Year

                                    28,            // Day
                                    22,            // Hour
                                    35,            // Minute

            // Write the DateTime as "Saturday, July 28, 1979 10:35:05 PM".
            System.Console.WriteLine("{0:F}", dateTime);

Visual C++

// Create a new instance of DateTime containing the date 
// 7/28/1979 at 10:35:05 PM using the en-US calendar.
System::Globalization::CultureInfo^ info =
   gcnew System::Globalization::CultureInfo( "en-US",false );

System::Globalization::Calendar^ calendar = info->Calendar;

System::DateTime dateTime =
   System::DateTime( 1979,      // Year
                     07,        // Month
                     28,        // Day
                     22,        // Hour
                     35,        // Minute
