Dates are so much part of everyday life that it becomes easy to work with them without thinking. Net also provides powerful tools for date arithmetic that makes manipulating dates easy. The Date Time structure represents an instant in time, typically expressed as a date and time of day Both the Date Time structure and the Date And Time module contain properties like Now and Today, so often beginners find it confusing. Visual Basic namespace and the Date Time structure belongs to the System namespace. For example, you specified Date literal of #2/6/2012# for the date February 6, 2012.
You can create a Date Time object in one of the following ways − Module Module1 Sub Main() 'Date Time constructor: parameters year, month, day, hour, min, sec Dim date1 As New Date(2012, 12, 16, 12, 0, 0) 'initializes a new Date Time value Dim date2 As Date = #12/16/2012 AM# 'using properties Dim date3 As Date = Date.
Read Key() End Sub End Module A Date literal should be enclosed within hash signs (# #), and specified in the format M/d/yyyy, for example #12/16/2012#.
Clear() End If End Sub 'Private Sub mtb App1_Type Validation Completed(By Val sender As Object, By Val e As Type Validation Event Args) Handles mtb App1.
Set Error(mtb App1, "The data you supplied must be a valid date in the format mm/dd/yyyy.") Else ' Now that the type has passed basic type validation, enforce more specific type rules.
