How can we convert date entered in (dd/mm/yyyy) format into (mm/dd/yyyy) format and vice versa at runtime?

First Convert the string date to a Date Object liek this.
' This date is in (dd/mm/yyyy) format
Dim myDateObject = CDate(myDateString)

Then use the format function to convert the date format to your required (mm/dd/yyyy) format.
Dim strUSDate As String = Format(myDateObject, "MM/dd/yyyy")

Note, that i have used the capital MM as in format function lower case m means minutes.
