Is there a framework class that converts the partial day strings on these forums to a DateTime? Examples are "a few seconds ago", "19 minutes ago" and 3" hours 26 minutes ago",

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

View 20 RepliesI have a form from which I am visually representing data (from access database). I have set up a user log on a separate form (allows user to make comments as they scroll through the data and see any points of interest etc). The second form is linked via a textbox in terms of a common field in this case the field name is "Datetime".
What I want to do is be able to scroll through the data and make notes on the second form and add them to another table in the database. I have managed to do all the above but obviously loose focus of the second form when i scroll through the data on the first. Is there any way of being able to interact with both forms at the same time?
I 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?

View 6 RepliesI have a Date variable called Time1In.
I'm getting a time value as a string from Excel, so I assign the date variable a value like this:
the string value coming in from excel is this:
30/12/1899 7:40:00 AM
my code gets the time value and assigns it to the date variable:
TimeIn1 = TimeValue(strTimeIn1)
the Date variables value is then this:
#7:40:00 AM#
which inserted into my database datetime field then looks like this:
0001-01-01 7:40:00
That causes errors when loading the page. I need to set a date value on the date variable. How can I properly append a date to the variable?

adding basically just the current date and time to a textbox/label or something like that? I have looked at coding but everyone seems to do it in such a complex way. Is there not a simple way of doing this? I don't want to use the date time picker as I don't want a user to be able to select the date or time.

View 2 RepliesWhat is the best way to retrieve the date and time from an online server instead of retrieving from the user PC? Some sample codes I found online can only request to a server which is window based which I can't find any free server to get.

I capture a gamesheet for a certain week. so if I select a date on a monthcalendar the sheet applies to the weeknumber of the selected date. When I save transactions I take the date at the last day of that week as the transactiondate. I need to store a datetime though because my query works of the datetime to get an accurate running balance. How can I append now() time part to my date variable and then store that in a datetime variable to get a transactiondatetime.
Here is my code for getting a transactiondate:
Dim dt As New Date
dt = Me.MonthCalendar1.SelectionStart
'get last date of week. Friday
Dim tdate As Date = dt.AddDays(5 - CInt(dt.DayOfWeek))
