Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.
I have a music related ASP.NET web site which caches a lot of static information from the database on the first request.Sometimes, the application is reset and cache is cleared while the application is on heavy load and then all http requests go to the database to retrieve that static data and cache it for other requests.
How can I ensure that only one request go to the database and cache the results, so that other request simply read that info from cache and not needlessly retrieve the same info over and over again.Can I use thread locking? For example, can I do something like lock(this) { db access here }?
actually i have 2 Similar questions:
1) i have a databse file on microsoft access. and i want to add system date in my databse using c#, what is the method to do this?
2) i m new in asp.net , i m making a demo application and storing a record of a person. there is a column of Date of birth. i used "datetime" data type for this column, because it have check on dates like i can't enter 29-02-2011, since its an invalid date. but problem with that it contain time with it, which should not be mentioned in date of birth column. plz guide me which data type shoul i use?
or if i simply use text data type and then add "regular expression" in textbox, then what regular expression should be used to have a check on invalid dates. remember i m not asking about the format of date, i m asking about invalid and valid dates.
I am pulling a date from an Access Database and inserting into my Dataset. I am assigning it to "myDate" and then assigning it to my SQL parameter @StartDate.

I am sure this has been covered many times but I can not find what I am looking for and I am sure it is simple.
I am trying to insert into an access database table a date taken from a calendar control or a textbox that the calendar control writes to.
Currently I am getting a "datatype Mismatch" error.
im trying to store a date in an Access database i set up the column in the db to be type Date/Time and have the following code to attempt to insert into itDim objTest As New OleDb.OleDbCommand("INSTERT INTO orderForm (OrderDate) VALUES (@OrderDate)", objConn)
objTest.Parameters.Add("
OrderDate", DateTime.Now)
Dim objTestExec As OleDb.OleDbDataReader = objTest.ExecuteReader()
however it yields the following error when i execute invalid SQL statement; expected 'DELETE', 'INSERT', 'PROCEDURE', 'SELECT', or 'UPDATE'.ive also had a variety of other errors with my efforts so im not really sure what the deal is here
I have an Access DB that generates reports for my users based on the month from a SQL table. In February my team leads didn't run the report and now it only shows data for the month of April. I have tried to play with the date code to pull just the February data but with no luck, I know this is a simple change but I can't figure it out.

I have to display data (names) in a random order on the website. The data is stored in a MS Access database. The names must be displayed in a GridView and DataList in different places. I have created a query in MS Access "zorder: Rnd([MarinaAccommodation]![ID])" which works fine in MS Access giving me a different order each time.
The problem is that when I try run it on the website the order remains the same, it does not change each time the page is loaded.
I have a situation where I am accessing a database multiple times and I'm wondering if it is necessary.
I have a GridView with a template column with a hyperlink to "Get Results" and on the RowDataBound event I have it check the batch number against the database and see if results exist and then if they don't, hide the link.
So when viewing the page if there is 20 rows in the gridview it is effectively doing 20 queries.
I was wondering if it is a better idea to query the database once with all "batches" and load it into a datatable, then on the RowDataBound event query the datatable. The only issue I see with this is there is currently 40,000 batches and grows daily.

I am starting a new project in ASP.NET (With silverlight) - I would like to get expert opinion about how to design the data access.I can use DataAccess Layer with SQL helper, but the challenge is every new field that I add needs to be added in the sql helper.I am trying to see if there is a way to design the system, so that it appears in the front end when a new field is added. I don't want to have in the ASPX files (binding in controls) I want to have ability to change items in code. Essentially I am trying to see the best option to have a database application.

So I have created a log-in screen that allows you to create a user at the same time. I wanted to make sure that if there was already a UserID registered that if a user tried to register with the same ID that an error message would show rather than my whole website crashing.

The code to place the data into the database works fine by itself but when I put it into this if statement the data no longer goes into the database.
If this the correct way to do this for making sure that a user cannot create a profile with a user id that is already present or is there a simpler way? I have tried to do it with a customvalidator but that did not work at all.
