Is there a quick and easy way to get internet time/date to use in a net application? I need it for creating a 15 day trial application, if I use local time/day user can simply change date before install and revert after. Using internet time I can simply add 15 days to it. VB.NET to C# [URL].

Thought I'd see if Stack overflow is quicker than me testing something while I get a thousand interruptions from other work :)
I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.
Writing the query in SQL I'd get the equivalent of
SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'
Ideally I'd use
SELECT * FROM table WHERE date=@input
and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance
Are those two comparable? Will I get the results I expect?
I am using VB 2008 and want to record a start date and time and then the stop date and time in a rich text box, i can get the start time into the box but so far can only stop the time instead of 2 seperate times, what i have is a drop down box with a list of computers 1-10 i was trying to get it so you picked a certain computer and that went into the text box then you started the timer and that was recorded, finally you stopped the timer and that was recorded but as i am a total newbie it does not work
Here is the code i have.

Title pretty much says it all. How do I format the date of a dateandtimepicker to insert it into the SQL date datatype?
View 20 RepliesI have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
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
Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)

I am using this line of code on form load event it is working very fine but i have to problems
1. It replaces the form name and display the date and time but i want to keep both date and time and forms caption separated by some space.
2. When form loads it load the current date and time but the time does not change it should run.
What should i do please please help me code is as follows
Me.Text = Date.Now.ToLongDateString & " - " & TimeOfDay
The problem that I'm having is that when I try to select a different date, the text doesn't go away. That may make no sence, but let me tell y'all what I've done.
1: Created a GroupBox
2: Put a DateTimePicker in the GroupBox
3: Put TextBoxs in the GroupBox
4: Changed the DateTimePicker to look like this:
A)Checked - False
B)Allow Drop - True
I thought that if I changed that, then the text in the text box would go to that specific date. It didn't do that, it just stays the same. What I'm trying to do is enter text in say 3/7/11 and when I choose date 6/12/12 it will display blank text boxes for me to enter something different.

View 2 RepliesI have a problem. I'm making a alarm clock and I need a way of converting a "dd/MM/yyyy HH:mm:ss" format into a date time format. This means I'll be able to compare the dates in a listbox using the for each function, to the current date and see whever it has passed and therfore the alarm should be deleted.

View 1 RepliesI am having a bit of trouble with using the date/time picker in a project.It is a program for calculating travelodge hotel accomodation prices. The price for a weeknight is 40 but weekends increase to �50.The code which I wrote is this:
For i As DayOfWeek = dtpArrival.Value.DayOfWeek To dtpDeparture.Value.DayOfWeek
If dtpArrival.Value.DayOfWeek = 1 Or 2 Or 3 Or 4 Then
PriceDecimal = PriceDecimal + 0[code].....
It does not work obviously because I am using the date/time picker for arrival date only. I think I need to use some other value which i would presume is something like "If DayOfWeek = 1 or 2 or 3...." but this will not work.
i have to validate date using date time picker such that u can't choose the date /month/year before you were born.
