1st question :
let see if textbox1 is date and time in, textbox2 is date and time out, textbox3 is calculate the days and hours. problem is the calculation is ok but when i put 25/4/2012 10:00 in textbox1 then textbox2 i put 26/4/2012 9:00 the answer should be 23:00 not 01:00. how to get exactly 23:00
