SQL Query To Retrieve Result Like This

I am using SQL Server 2005.

I have a table with records like this:

Date EmpID ADCode ADAmount
----------------------------------------------------------------------
01-Jul-07 101 GPF 150
01-Jul-07 102 GPF.ADV 100
01-Jul-07 103 GPF 250
01-Jul-07 103 GPF.ADV 200
01-jul-07 104 GPF 300

I want to show results like this using a single SQL query:

Date EmpID GPF GPF.ADV
-----------------------------------------------------------
01-Jul-07 101 150 0
01-Jul-07 102 0 100
01-Jul-07 103 250 200
01-Jul-07 104 300 0


I tried:

select PaySlipDate,EmpID,
case ADCode when 'GPF' then ADAmount else 0 end GPF,
case ADCode when 'GPF.ADV' then ADAmount else 0 end 'GPF.ADV'
from EmpSalaryRecord

It is showing like this:

Date EmpID GPF GPF.ADV
-----------------------------------------
01-Jul-07 101 0 0
01-Jul-07 101 150 0
01-Jul-07 102 0 100
01-Jul-07 103 0 0
01-Jul-07 103 250 0
01-Jul-07 103 0 200

It is showing multiple records of each employee for each date. First a record with GPF and GPF.ADV both zero and then records with values. I want a single record for each date and employee.
