[Urgent] Timing Allocation Problem

[evios]

Lets say i do this to count the number of that particular hour:
If vDateTime.Hour > 0 And vDateTime.Hour < 24 Then
Dim hour As Integer = vDateTime.Hour
If hour = 0 Then
hour = 24
End If
count(hour, 0) = count(hour, 0) + 1
Refer to the data below:
1.2008/06/24 02:00
2.2008/06/24 12:00
3.2008/06/24 06:00
4.2008/06/24 17:00
5.2008/06/25 06:00
The first will be allocated to hour=02 and the second one will go to hour=12.
However i face this problem: How if 3 and 5 having the same hour but different date? I need to get the date as well. Can i solve this problem using almost the same coding format above? I need to keep count(hour, 0) = count(hour, 0) + 1 this way. Thanks a lot.

You should always parse the date, rather than the hour, but you can also use DAY()

Now i already simplify my coding to the format below:
I need to allocate the 24-hour time selected by the user to an array of size 24, for example, If the user choose 2day 8AM until tomorrow 7AM, Then my idea is:
hourarray(0)=8AM
hourarray(1)=9AM.....
..hourarray(23)=7AM...
How can i loop it? Thanks

your fields ahould be date/time. you can use a function to change it to hour minute or second

Okay ..

Look up DateDiff function.. and set up your code to do something alond the lines of ...

1) Get start date and time..
2) read in DATA ..(first/Next record)
3) Compare data(2) to start date (1) and skip all data before start date (go back to 2)
4) Get the Datediff of data(2) date and start date(1)
5) if Datediff day = 1 (more than 24 hours) go back to 2..
6) do your count...

Hope this Helps...

Why VB6 style solutions in the VB.NET forum...

Simply use DateTime and TimeSpan...problems all solved with no explicit parsing or even calculating....
