So i wanted it sorted by when they were created (not to fussed either ascending or descending). i tried using the code below with no luck, This adds multiple of blocks of the same files on the selected date

I've got a datatable with a DateTime field that I want to sort using a DataView. I only need the Time part of the column though, and not the date. I can't get it to show just the time and not the date as long as its a DateTime column. I know I could convert it to a string to get the time, but then it wont sort correctly.
View 1 RepliesI want to save datetimepicker value of date and time in two separate text files. Currently, when I select a date from datetimepicker and save it in a text file it saves both date and time as below:
5/11/2011 8:25:06 PM What I would like to happen is as below: Datefile.txt saves 5/11/2011 Timefile.txt saves 8:25:06 PM Alternative solution that can work for me would be, if the time (only the TIME) can be modified after saving as below: saved datetime into text file is 5/11/2011 8:25:06 PM
How can I modify the time only to say 12:00:00 PM. By doing so I would like to keep time as 12:00:00 but date can be changed by the user using the datetime picker.
In a typical session with the program I'm writing, the user needs to be able to access the data in 1 to 500 (maybe) tables (but always only one table at a time). Up to now I've been creating these single table datasets dynamically, as and when required.I've now come across the distinction between typed and untyped datasets (where typed seems to be the recommended option). It seems, though, that typed datasets are created at design time only and not dynamically. Is this correct? Are all of my dynamically created datasets therefore untyped?

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 6 RepliesI'm building an application in which a certain CSV schedule is read and searched for time and date values.
I want to read each cell in the CSV file with a streamreader and have VB determine if the contents of the cell represent a date (like 31-10-2011), a time (like 22:30) or random text data which is not formatted like a date or time.
How can I make VB recognize a string as either a date, a time or neither one, so I can use this string formatted as Date, Time or discard of it?
The contents of the CSV file will look something like this:
;Schedulename;text;text;31-10-2011;text;text;6-11-2011;text;;;text
Although the CSV file will never contain much data, the position of the date and time fields in a row may vary, so I cannot tell VB which cell to read as date/time. It has to recognize the value as date, time, or unusable text.
Dim CSVReadline As New System.IO.StreamReader(schedule.csv")
Cellcheck = CSVReadline.ReadLine()
String = Cellcheck.Split(";")
For i = 0 to 10
Scheduledate = String(i) ............ etc.

View 8 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?

Using the System.Windows.Forms.DataVisualization.Charting objects/namespace, am having problems getting by chart to sort axis of dates properly.My data looks like this (dates in US format):
Product Quantity SaleDate
A -- 2 -- 5/1/2011
B -- 1 -- 5/1/2011
C -- 1 -- 1/1/2011
B -- 2 -- 2/1/2011
I'm creating a stacked column graph like this, where dv is a dataview of the datatable:
vb.net
chSales.DataBindCrossTable(dv, "Product", "SaleDate", "Quantity", "") chSales.AlignDataPointsByAxisLabel() For Each cs As Series In chSales.Series cs.ChartType = SeriesChartType.StackedColumn cs.YValueType = ChartValueType.Int32 cs.XValueType = ChartValueType.DateNext
So this produces a stacked column graph with 2 A's, 1 B in May 11, etc But the date order is Feb, Jan, May, regardless of how I sort the datatable provided to the chart.
