Getting all days of month from inputbox?

Hi All-
Does anyone know of a way to get/calculate ALL of the days of the months from a date range entered into an inputbox in which a user may enter any day of a month? In other words, the user enters 9/14/2009 in the first inputbox then 10/8/2012 in the second and code would calculate the number of days as 9/1/2009 - 10/31/2012.

Here is the current code I'm using that calculates only the exact days:

Dim DBstarts As Date
Dim DBends As Date

DBstarts = InputBox("Enter the Date that DB begins:")

DBends = InputBox("Enter the Date in which DB ends:")

daysofDB = -(DBstarts - DBends)

MsgBox daysofDB

[/SIZE]

Use dateDiff

    Dim DBstarts As Date
    Dim DBends As Date
    Dim daysofDB As Long

    DBstarts = InputBox("Enter the Date that DB begins:")

    DBends = InputBox("Enter the Date in which DB ends:")

    daysofDB = DateDiff("d", DBstarts, DBends)

    MsgBox daysofDB

Perhaps:

Sub example()
Dim DBstarts As Date, DBends As Date, daysofDB As Long
DBstarts = Application.InputBox("Enter the Date that DB begins:", "Start Date", Type:=1)
DBends = Application.InputBox("Enter the Date in which DB ends:", "End Date", Type:=1)
If DBstarts > 0 And DBends > 0 Then
    daysofDB = (DateAdd("m", 1, DBends) - Day(DBends)) - (DBstarts - Day(DBstarts) + 1)
    MsgBox daysofDB
End If
End Sub
