it's a log in form and I need to put case-sensitive validation in other words if your Username = Admin then Admin != admin Consider this code block (VB is really unfamiliar for me so break it to me gently ^^) This is after it has matched a record in the database to the parameter passed to the function LogIn()
If dataTable.Rows.Count > 0 Then
'case-sensitive Validation follows
'data in Column ID and Password are placed in variables
[code]....
the asterisk-ed line returns an error (obviously) as strId is not of data type String.I also tried using LIKE but again since strId and strPass are not Strings, all I get is an error.

i've been attempting to update a DateTime Field in a MySQL Table i've created via vb.net. I've made many attempts however i'm still getting the error that i have an error in my SQL Syntax. The format that the DateTime in Vb.net is 6/21/2011 12:46:25 PM. I need to convert that to the MySQL DateTime Format which is 2011-06-21 12:46:25 and also is running on a 24 hour clock. I've searched many forums and haven't found a conclusive solution yet. Below is the code i have so far, with attempting any DateTime Conversion.
Imports MySql.Data.MySqlClient
Public Class FinalFailedPinNumberAttempt
Dim connectionstring As String = "Server=localhost;user id=root;Password=;database=mylaundrycompany"
Dim SQLConnection As MySqlConnection = New MySqlConnection

I have a query from within my vb.net code which searchs for a record by date. The date being entered via the code is in format dd/mm/yyyy, i need to search in the database using yyyy/mm/dd? Ideally i thought there may just be a function within MySQL which will convert this. If not in vb.net to convert the string 01/01/2011 to 2011/01/01?

I want to insert only date into the db but in the following statement that I've wrote which inserts the date in mm-dd-yyyy hh:mm:ss format.
InsertCmd = "Insert into Blotter (Name, Product, Date_Time) values ('" & NameLabel.Text.Trim() & "','" & ProductTextBox.Text.Trim() & "','" & TimeLabel.Text.Trim() & "')" & "Update Blotter Set Name = UPPER(Name)"
I have tried the following code, however it didn't work.
InsertCmd = "Insert into Blotter (Name, Product, Date_Time) values ('" & NameLabel.Text.Trim() & "','" & ProductTextBox.Text.Trim() & "','" & (CDate(TimeLabel.Text.Trim().ToString("MM/dd/yyyy")))& "')" & "Update Blotter Set Name = UPPER(Name)"
[code]
I also tried format the TimeLabel as below but still didn't work. [code] TimeLabel.Text = CDate(DateTime.Now).ToString("MM/dd/yyy")

I'm looking for a way to convert a 5 character time representation to a date object. ie. "0937a" should be "6/16/2010 9:37 AM" or "1215p" should be "6/16/2010 12:15 PM".

I have a machine which creates a new log file at the beginning of the day(12am) and updates the log file whenever there is any changes until the end of the day. How do I import the data in real time (30 sec, 1min or whenever there is any changes) to my SQL server database? Will SQL Server 2008 be able to access the active log file? If not will it be easier if I let my machine create a new log file whenever there is any updates? But if it is so, how do I import so many log files with different names in real time. (I must be able to scale the solution up to multiple machines).

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?

Weird problem that just started, I am using an OleDbCommnad to create a dataadapter then fill a table everything from a .csv file, works fine except no dates are coming over? I added a datagrid view to my project just to see and any column that should have a date value is empty. I confirmed that the column is of System.DateTime value so I am at a complete loss?

I'm trying to create an auction site using asp.net. My auction's start date & time and end date & time are stored in my sql server 2008 r2 database as datetime types. I'm using vb.net. I'm trying to create a select statement in which I can query the date and time portion relative to the current date and time (so as to only display current ongoing auctions). I can successfully query the date portion using the Date.Now function, but the time is giving me a hassle. DateAndTime.Now doesn't work. I've even tried to separate the time and date in the database, but I still can't get an effective query. Here are two examples of code which I've tried:

I am doing work on a new logging database that I have decided to use UTC datetime to store all datetime values since our company spans timezones and multiple sources and timezones are logging events.However the problem that I cannot get my head around is formatting the datetimes in my datagridview for my user application.Our applications use mostly LINQ to SQL to manipulate our data from generic SQL CRUD calls, so I am hoping I can mask/format the DGV to get the conversion or some LINQ function rather than having to write special SQL stored procedures to do it every time I need to display the data.. (I have found multiple sources that explain how to do that)

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

I want to find out from the list which is the closest one approaching Now.ToUniversalTime but am having difficulty trying to work it out I had it looping through like this but this isn't much good as I only want to return the one that is the closest approaching to the system time. If TodaysCard(i).eventDate.ToUniversalTime < Now.ToUniversalTime

I am building an application that needs to store different time of day values in dateTime fields of an Access database.I am trying to enter the time value's via a DataGridView using TextBoxColomn s.The coloms are formatted with the defaultCellStyle property to show only the time part of the datetime.After i save the entered data and look in the database itself, i see not only the time, but also the (current) date in the datetimefields. This raises a problem when i want to compare the timevalues later on in the functionality of the program i am building.(Of course it is simple to seperate the date and time part in coding of the program, but it would be more elegant (i think) if i could just save only the time part in the database (and have the date part of de datetimes left to 0))I have tryed via the CellFormatting and the CellParsing events, but no luck.I am new to visual basic and probebly missing out on something.
