Stored Procedure always returning 0

Question

I am trying to get returned value from stored procedure, but it always returning 0.

c# code

cmd = new SqlCommand();
    cmd.CommandType = CommandType.S

You do not have an out parameter in your stored procedure, and you are using ExecuteNonQuery -- basically, client side you aren't giving the reurn value anywhere to go. In C# terms it's as if you called a function, but didn't make it part of an assignment. x=getX(); vs getX();

You can fix this by either changing the stored procedure sothat it has an output parameter

ALTER PROCEDURE [dbo].[AbsentEntry] 
    @EmpID varchar(10), 
    @AttendanceDate Date,
    @returnval     int OUTPUT

AS BEGIN

    IF (SELECT COUNT(*) FROM tblEmpAttendance 
        WHERE EmpID = @EmpID AND AttendanceDate=@AttendanceDate) = 0
    BEGIN
        insert into tblEmpAttendance (EmpID, AttendanceDate, IsInOut,
        SessionCount, IsPresent) values ( @EmpID,@AttendanceDate,'OUT',0,'A')
        set @returnval=1
    END
ELSE
    BEGIN
       set @returnval=0 
    END
END

Or, more simply, by using ExecuteScalar and assign the result to a variable.

int result = (int) cmd.ExecuteScalar()
