Date / Time Stamped And Numbered Filenames When Saving To JPEG?

Oct 19, 2009

Right now the existing VB code I have uses GUID to generate "random" filenames on save.
For instance:
ff8514d389a041649fd8b925a32f2b51.jpg
e1c938560fc1464ab2138065fc4661d3.jpg

Instead I want a date stamp, Time Stamp, and numbered filename:
For instance:
20091015_131644_001.jpg <--(Date_Time_NumberIncrement)
20091015_131551_002.jpg

Or something along those lines. The current code (which saves a jpeg to a random GUID filename) is below:
Imports System.Web
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.IO

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?

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

DB/Reporting :: Search A Table, Confining To A Specific Date Range Based On A Date-time Column?

Jul 14, 2009

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)

Date Time Picker - When Select A Date, The Text Does Not Go Away

Apr 7, 2011

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.

Converting Date And Time Format To Date?

May 3, 2010

I 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. It is currently in a string form so I can't use < and > to compare it to the current date as that is in a date form. I've tried using CDate but it doesn't work as it only will convert these formats:

"August 12, 2004", "2:07:30 PM" and "August 12, 2004 2:07:30 PM"
