Day Function (Visual Basic)
Returns an Integer value from 1 through 31 representing the day of the month.
If you use the Day function, you might have to qualify it with the Microsoft.VisualBasic namespace, because the System.Windows.Forms namespace defines Day as an enumeration. The following example shows how qualifying Day resolves this ambiguity:
Dim thisDay As Integer = Microsoft.VisualBasic.DateAndTime.Day(Now)
You can also obtain the day of the month by calling DatePart and specifying DateInterval.Day for the Interval argument.
The following example uses the Day function to obtain the day of the month from a specified date. In the development environment, the date literal is displayed in standard short format (such as "02/12/1969") using the locale settings of your code.
Day is qualified to distinguish it from the System.Windows.Forms.Day enumeration.
