hye there.., I just finished designing & writing codes for a customer information and , however after it has been connected to the database only one the datetimepicker can be click, and the rest of the function including in the form are not working!it seem that the form stuck and NOT responding. i cant even close the form (X button), so i have to stop the process using compiler (visual studio 2008), however if i press the 'Delete' button before the 'Add' button, it will successfully delete the data.. but if i disconnected the form from the database, the both of datetimepicker will work and able to view the date interval (after pressing the 'Calculate Period' button)= how to make it appear automatically in screen without using the button? below are the code, I try to make some other form.. but it is still the same
