Validate the time as a String




Here is how to validate the time as a String  like 10:59 in VB.NET

Use regular expressions to do this using the below example

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Imports System.Text.RegularExpressions





  Dim intRegexPattern As New  _
  System.Text.RegularExpressions.Regex("^([0-1][0-9]|[2][0-3]):([0-5][0-9])$")
        If Not intRegexPattern.IsMatch(some text) Then


' Now do something if it does not match

end if


@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
