I have a datagrid in VB2008 currently set up with a column that has dates. I want to be able to calculate the number of calendar days of the Disp Date Column to today's date. Almost like the days360 formula in Excel. I cannot do it in Access as it is a linked data table and cannot do it in excel as the spreadsheet is being updated by the server throughout the day.

How do I calculate the difference between two dates to display as a number in days?I have 2 text boxes (txtHStart_Date & txtHEnd_Date) I have used an Ajax Calendar Extender to enter the dates in each of these text boxes.I would like to get the difference between these two dates to show in a seperate text box (txtNoOfDays)
I've seen the timespan function but can seem to get this to work. I'm not to sure how to declare the text boxes as the dates I would the calculation to be made from
Code:
Dim D1 As Date
Dim D2 As Date
Dim ts As New TimeSpan
D1 = txtHStart_Date.Text
D2 = txtHEnd_Date.Text
ts = D2 - D1
But I know this isn't right. I also don't know how to get it to display in the 3rd TextBox.

View 2 Replieshow do i get total no of days between two days which might include leap year
right now i'm getting the no of days by using DateDiff function in vb.net. but i reckon it is not precise. cos it is not validating leapyear.
I need this for 2 different changes.ON one form i got a week calendar, the other a month calendar.Was hoping to add 2 buttons previous & next.To scroll back in time x days, or x days forward.And similar for the months, but instead of days months.Can anybody give me a exaple or a method how to get this to work?Figured it could be done with a loop, but not sure anymore.

I have a date in the future e.g. 13/10/2008 I need to subtract the current date (today is the 28/09/2010) minus 7 days, so thats 21/09/2010 minus 13/10/2008, which would equal erm, 720 something ? But the current date won't always be 28/09/2010, obviously. I need the code for this. EDIT: When i said future I mean past :)

Lets say every 7 days you manually kick off a VB.net program that moves all old files to an archive zipped folder; and you run this same code every 7 days BUT at some point in time you need to go into that zipped folder and delete every file that is 100 days old........What would you suggest I add to the code I have now, that would automatically un-zip the file (I assume I do need to unzip it first) then do the delete of the files that are 100 days old or older? I am thinking I need to set a timmer or somthing to trigger in 100 days from now then reset it once it is triggered; am I on the right track here???
