Perhaps you can use Hour(Time), Minute(Time), and Second(Time) to get the hour, minute and second respectively for each of the two time points.

Use the datediff function.

TimeDiff = DateDiff("n", Time1, Time2)

will give the time difference in minutes. For difference in seconds, use "s" instead of "n". Look up the datediff function in the Help files to see the syntax and various parameter options

in vb you can get the current time by using now()

HI

you need to set the Time Difff in text3 control right, then use the following code under any event

text3.text=DateDiff("n",cdate(text1.text),cdate(text2.text)

it is suggeted to check for the valid time entry by using the isdate function
Ex:
if isdate(text1.text)=false then
msgbox "Not Valid Time"

end if

hope this will help you,
