VS 2010 Recognize Time And Date In CSV File?

Mar 28, 2011

I'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.

VS 2010 - How To Include Date / Time In Title Of Text File

Mar 7, 2012

I'm doing an error log in my code and I'm trying to output the errors to a text file with a specific date/time in the title so they can differentiate. I've tried things like
logname = "C:Documents and SettingsSeDingDesktopErrorserrorsLog " & DateTime.Now.ToString() & ".log"
But I get this msg "The given path's format is not supported." all the time.

How To Recognize Time Past

Sep 1, 2009

How do I make my program know that time is passing and interact with it? Currently I'm trying to use a method like this:
Imports System.Globalization
Private Sub CurrentTime_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CurrentTime.Tick
Dim date_info As DateTimeFormatInfo = _
CultureInfo.CurrentCulture.DateTimeFormat()
ToolStripLabel1.Text = Now.ToString(date_info.ShortTimePattern)
End Sub

That sets the current time to ToolStripLabel1.Text it looks like: 10:25 PM. Then I made another timer, realizing I couldn't interact with Toolstriplabel1.text because the time contains " : and PM", and this timer does this:
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
TextBox48.Text = Val(ToolStripLabel1.Text)
End Sub

Basically it takes the value of toolstriplabel1 which would be "10" it gives a variable 1-12 in accordance with the current time. Then I have another timer that handles the main process, and in My.settings I have a variable:
My.settings.12hourspassed

So I was going to use My.settings.12hourspassed as a variable such as My.settings.12hourspassed = My.settings.12hourspassed + 1 - whenever the time (textbox48.text) goes to 12.
Private Sub Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer.Tick
If Val(TextBox48.Text) = 12 Then My.settings.12hourspassed = My.settings.12hourspassed + 1
If Val(TextBox48.Text) = 12 Then TextBox48.Text = "1"
End Sub

The problem is that I cant do textbox48.text = "1" because another timer is making it the value of the current time.. So whenever textbox48.text = 12 it constantly does: My.settings.12hourspassed = My.settings.12hourspassed + 1...

I know that this method completely skips an hour and such.. accuracy isnt all that huge. Any way to tick off whenever 12 hours have passed? and if the program is turned off a way to compare the current date with the date the program turned off at to see how much time has passed while the program is off?

How Does DotNet Handle Parametrized Dates Where Programmatic Date Has No Time But Sql Date Has Time

Jul 16, 2010

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?

C# - Convert A Date And Time To UTC Time Based On The Time Zone Of The User?

Sep 6, 2009

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?

Current Date/time In File Friendly Format?

Jun 3, 2011

My current program is reading a XML doc and using it then moving it to a different directory to be archived once it is finished using the xml.

I want to be able (upon completion) move and rename the file to a new folder, I want the folder to be the current date/time as well.

So basically have 4/4/2011 9:56AM.xml in the folder 4/4/2011 9:56AM.

getting the function DateTime.Now in a format that can be saved. Folders and files cannot contain the " / " or " : "

A more Sql server type of date would be fine like 24-Jun-89 13:32:22 but I don't know how to get something like that.

Convert Excel Date To Sql Server Date Time Format Using ACE Provider?

Jun 24, 2011

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
