I am using VB.NET. Is there a date function that calculates the date based on the number of months I have given?
for example, if i say July 2009 and looking for 10 months back, it should return Sept 2008.

For example, today is 05/11/2009, I have two text box.
Actually it means that whatever what date i choose within the current month, the two textbox will display the last three months date.
For Example, Current Month is November 2009 , Textbox 1 will show 01/08/2009, Textbox 2 will show 31/10/2009.
Another example is Current Month is January 2009, Textbox 1 will show 01/10/2009, Textbox 2 will show 31/12/2008.
May I know how the vb.net code should look like?

I am in ethiopia and we have 13 monthes. 12 of them with 30 days each and 13th month with 5 or 6 days. I want to sort my data by date using the bindingsource sort method. But to do that I need to set my date field a date data type. When i set the datatype to date, i can't enter some values like 13 for the month value and 30 for day value of 2nd month.
What I want is just to make my application accept 13 as a month and 30 as a day for all monthes, so that i can sort my data by date. Is it possible to do so by setting culture for my application or by some other means?

I have an access database with a table called [yearly stats cape town] This table has the following relevant columns to my query. [CASE NO], [B/W/C] [1ST APP MAG CRT].The goal of the windows form I am doing is to return the total number of unique case where [B/W/C] = C (in custody) and [1ST APP MAG CRT] contains a date longer than 6 months ago from the current system date. To determine the total amount of cases I use the following query.
SELECT COUNT(*) AS [CASE NO]
FROM (SELECT DISTINCT [CASE NO] AS [CASE NO 2]
FROM [YEARLY STATS CAPE TOWN]) derivedtbl_1

I have an older program that I wrote some time ago in VB then late updated for VB.Net. The program calculates the ephemerides of comets based on orbital elements downloaded from the Minor Planet Center website. I am now trying to make an iPhone/iPad application using the same idea and the same calculations. Unfortunately I am too new at objective-c that trying to convert the extensive calculations is proving quite difficult for me.

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:
Select [Date Created] From MyWorksheet

I have a string that holds a value in the format of ddMMyyhhmmss.
Example 240512024707
I need to be able to convert this date to a real .NET Date object.
I am currently using CDate but it seems CDate does not recognize the format, is there any way of specifying the string format to CDate ???
row.Item("NoteDate") = CDate(n.noteText.Substring(0, 12).ToString).ToString("dd/MM/yyyy hh:mm:ss")

I am trying to convert a string into Date (to put it later into INSERT command). My problem is that the string I am reading is always different (there is no rule what format it is going to be - as this is user-dependent).I found such piece of code on the stackoverflow:
DateTime myDate =
DateTime.ParseExact("2009-05-08 14:40:52,531",
"yyyy-MM-dd HH:mm:ss,fff",
System.Globalization.CultureInfo.InvariantCulture)
but in my case it will not work as I don't know what kind of format I am going to import.Is there any universal import function which checks all known formats? If now how should I write it?
