                    ad.UpdateCommand.Parameters.AddWithValue("@Emp_id", label4.Text.ToString());

my database table has
ID,
Emp_id,
Lname,
Fname,
Mname,
Time_In,(this is for AM time)
Time_Out, (For AM time)
TimeIn,(for PM time)
TimeOut,(for PM time)
Date

i like to save time in and time out for both AM and PM in one Row for a specific Emp_id per day

The first thing to do is to test the value returned by ExecuteNonQuery. If it's not zero then data was saved. In that case you are simply looking in the wrong place or at the wrong time for the data. Can we see your connection string?

yes i can see but it doesn't save.. it says it has been updated but when i look at my database nothing has change.

 [COLOR=#333333][FONT=Consolas] ad.UpdateCommand = new OleDbCommand("update Attendance_Records set " + " [Time_Out] = @Time_Out " + " where  Emp_id = @Emp_id and Date = @Date", cn);[/FONT][/COLOR][FONT=Consolas]

thats my connection string

 

[jmcilhinney]

That is not your connection string. That is your SQL code. Your connection string is the string that you pass to your connection object. You also didn't mention anything about the value returned by ExecuteNonQuery.
