im trying to find time diffrence between two times... in hours,mins,sec

10/24/2004 12:12:47 AM
10/24/2004 12:12:49 AM

in this case its 0 hours, 0 mins, and 2 seconds

Use the DataDiff function ... example:

Date.Subtract returns a TimeSpan object, from which you can get the total days, seconds, minutes, etc.

Msgbox(Date.Subtract(Now, MyDate).TotalSeconds.ToString)


Dim a as Date = #10/24/2004 12:12:47 AM#
Dim b as Date = #10/24/2004 12:12:49 AM#
Dim diff As TimeSpan = b.Subtract(a)

Then you can access to all the TimeSpan properties : for example diff.Seconds() to have the number of second elapsed between a and b.

I agree with KGreg and Glom but if you are getting the dates as strings then use DateTime.Parse() first to convert them to dates and then proceed to use the .Subtract() function with the TimeSpan() class:

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim strDateA As String = "10/24/2004 12:12:47 AM"
        Dim strDateB As String = "10/24/2004 12:12:49 AM"

        Dim dateA As DateTime = DateTime.Parse(strDateA)
        Dim dateB As DateTime = DateTime.Parse(strDateB)

        Dim ts As TimeSpan = dateB.Subtract(dateA)

        MsgBox(Format(ts.Hours, "00") & ":" & Format(ts.Minutes, "00") & ":" & Format(ts.Seconds, "00"), MsgBoxStyle.Information, "Difference")
    End Sub
