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?
Given a week number, I need to get the date of the Monday of that week.For example, I have several strings that are stored in a file, such as
"WK 28 2010"
"WK 30 2010"
They could be any any valid week number.
The Monday on Week 28 of the year is 12 July 2010
The Monday on Week 30 of the year is 26 July 2010
Its these dates that I need.
I guess I could create a lookup table, but would prefer a more smarter approach so my software will be future compatible?
I have a ticketing application and I want to create a date based, sequential, ticket number.I'm leaning toward something based on Posix time as this generates a sufficiently large number and the likelihood of any two ticket numbers overlapping is slim to none (two people would have to just happen to hit the button at exactly the same time on two perfectly synchronized systems).Has anyone done anything like this or have any code snippets/ suggestions? At the moment, I'm just using a UNIX time converter someone posted elsewhere: [code] This works fine (although it's not POSIX time), but I wanted to see if anyone else had any feedback as well.

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

View 1 RepliesI need to generate a report that shows the 52 weeks of a year (or 53 weeks as some years have) and their start and end dates.

View 7 RepliesI am debugging an application that I ported from Windows, to *nix, a little while ago. The app stores dates as doubles (using the OLE Date format). I need to be able to inspect the dates - as human readable strings. I cant find an online conversion tool, so I decided to roll my own.
I was originally going to write an OpenOffice function, but I think it would be more straightforward to use one of the .Net languages, to write a small console app that accepts the double as a parameter and prints the date string to the console.
I am relatively new to .Net (though I have dabbled with both C# and VB.Net in the past). Can anyone help with my main() function? - snippets in either VB.Net or C# will be equally useful.
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 :)

if the date in A1 is between 1st Jan & 14th Mar use -8
if the date in A1 is between 15th Mar & 15th Oct use -17
if the date in A1 is between 16th Oct & 31st Dec use -8
Then deduct the above value from B1 to give a target for each row (from 3 onwards)if the target is < the value in n then change background orange in f
I have most of this working, but there are some issues yet. Basically, it's a "History" form for patients There's a date field for each entry, and if that date doesn't match the date you're accessing the form I want it to disable all controls so you can't edit the form.So it would have to check the current date with the date that is on the form.The issues I'm having are this. It seems to work because when I click today's date nothing gets locked like it used to, but when I do click another date everything in that form gets locked, including the override button and the scrollbar. I don't want the scrollbar locked, and I want to have an override button so the user can edit the form if they truly wish. It also locks the DateTimePicker so I can't pick another date, I don't want that locked either.I tried enabling the DTP in the sub below but it must get ignored
