Difference between DateValue and CDate in VBA

Question

I am new to VBA and I am working on a module to read in data from a spreadsheet and calculate values based on dates from the spreadsheet. I read in the variables as a String

Answer 1

Both CDate and DateValue, when used in vba, converts a value to a Date (dd/mm/yyyy format):
1)
LstrDate = "July 24, 2014"
LDate = CDate(LstrDate)

2)
LDate = DateValue("July 24, 2014")

Both return the same result.

However DateValue returns the serial number of a date if used in application level (spreadsheet)
