    vba > subtracting time

    how do i subtract time??

    i'm trying to make a time sheet that could
    calculate the number of hours. like say
    i timed in at around 8:00 AM and i
    timed out at around 3:00 PM. how do
    i get the number of hours that i consumed
    for that day?


    i was thinking that if i do this > 12 - 8 = 4 then
    add the 3 which makes it 7. but the value doesn't
    work bec. i figured that you can't subtract an INTEGER
    to time. the answer doesn't come up right.

    OR maybe if i assign a value to each of the time,
    do you think it will work??

    EX. If Me.Text67.Text = "2:00 AM" Or Me.Text67.Text = "2:00 PM" Then
    Text67.Value = 2



    please help please help

    We need more info.

    What is the data type of the fields in the table? (date, text, integer)
    What are the field names?
    If the data type is Date, then you would use the DateDiff() function.

    If the data type is text, integer or the controls on the form are unbound,
    then it is more involved in doing the calculation.

    BTW, rarely do you need to use the Text property of a control. The text property is actually the uncommitted (new) data of a control as opposed to the Value property (old data).
