I have a table name timelogTB and it has 5 column named; LogID(PK), EmpNo(FK), Time_In, Time_Out and Date running in form1. 
Then in form2 I have a combobox where the Employee # of an employee can be selected and when I will select an Employee # the total number of days worked of that employee will display in a textbox using 2 date time picker, 
the dtpicker1 is labeled dtpFrom and dtpicker2 is labeled dtpTo. 
The column Date in timelogTB is only recording the date when the employee is time in using also a date time picker. 
I am looking forward for a favorable answer guys, as much as possible I want you to explain it more simpler and precise because I am new in vb2010 
thanks in advance!
