I'm building a program to calculate the cost of hiring a trip and need to calculate the waiting time. How can I do this from the two text boxes where you input the numbers. The two textboxes are: txtTimeOfArrival txtTimeOfReturn I need the difference in minuets, the input is HH : MM Please reply quick it's for my A level work and my teacher doesn't know!!!
dim timeOne as variant 'or use date dim timeTwo as variant ' or use date dim waitedtime as long if not yourtextbox.text = "" or not yourtextbox2.text = "" then timeone = format(yourtextbox.text,"dd/mm/yy hh:nn") timetwo = format(yourtextbox2.text,"dd/mm/yy hh:nn") waitedtime = datediff("n",timeone,timetwo) else waitedtime = "you have entered invalid time format text " end if when ever you are using dates , when your text box lost the focus immediately you should cross check the value you entered is in proper date/time format; hence better use any calender control or else use any function to cross check it.
