T-SQL fill rows with same date between dates

Zones: MS SQL Server, SQL Server 2005
Tags: Microsoft, SQL Server, 2005
READ FIRST: I already have a date table, just call it "tblDates".  How do fill in the dates with the same data as the previous record unitl it changes?

I have events for employees in a table "EmpEvents":
EmpID   eDate          eEvent           eSch          eClass
100       1/1/2008    1                    51              11
100       1/3/2008    7                    32              50
100       1/15/2008  3                    88              8
100       1/20/2008  9                    23              43

I need it returned as follows using a stored procedure (THIS HAS TO BE DYNAMIC, NO ADDITIONAL TABLE UNLESS THEY ARE TEMP IN MEMORY).  Basically fill in the missing days with the same information as the previous record until it changes as follows:
EmpID   eDate          eEvent           eSch          eClass
100       1/1/2008    1                    51              11
100       1/2/2008    1                    51              11
100       1/3/2008    7                    32              50
100       1/4/2008    7                    32              50
100       1/5/2008    7                    32              50
100       1/6/2008    7                    32              50
100       1/7/2008    7                    32              50
100       1/8/2008    7                    32              50
100       1/9/2008    7                    32              50
100       1/10/2008  7                    32              50
100       1/11/2008  7                    32              50
100       1/12/2008  7                    32              50
100       1/13/2008  7                    32              50
100       1/14/2008  7                    32              50
100       1/15/2008  3                    88              8
100       1/16/2008  3                    88              8
100       1/17/2008  3                    88              8
100       1/18/2008  3                    88              8
100       1/19/2008  3                    88              8
100       1/20/2008  9                    23              43
100       1/21/2008  9                    23              43
100       1/22/2008  9                    23              43
