Access :: Reading Data From Access With A Linked Table (pointing To A Access Table On Another Location?

Sep 7, 2010

Here's a short explanation of my asp.net project.

1) the default page loads, it will read the Windows Login of the user opening the page.
2) I'll check if this login exists in a table stored on the webserver.

In this Access Database, there's a 2nd linked table, pointing to another access table on a network location. Now, I want to read data from this linked table. However, at this moment I receive an error:

"The Microsoft Jet database engine cannot open the file '\<ip><shared-folder>statistics.mdb'. It is already opened exclusively by another user, or you need permission to view its data".

Some extra info:

- The network folder has read and write permissions for everyone

- the user and group permissions on both access files are set to read/modify/administer for the Admin user (on the tables I want to read from)

- IIS authentication on the server is set to "Windows Authentication" (this is needed so I can read the Windows Login from the user). All other authentication modes are disables (like anonymous, ...)

- When the error occurs, no other program or process has access to the statistics.mdb (so, it can't be locked by someone else)

- the web.config files access connection string looks like:
<add name="AccessConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\<IP><shared-folder>statistics.mdb;User Id=admin; Password=;" />

Like I said before, in this statistics.mdb file, there are 2 tables. One normal table, and another linked table (pointing to a network location)

Searching for solutions, I discovered the following:

- if I don't use linked tables, everything works fine (however, I have to use this linked table)

- even if I connect directly to the table in the network I receive the error. So, I'm pretty sure I don't have sufficient rights to read from this table.

I read that not the Admin user is opening the file, but actually a user called ASP.NET. This user doesn't have the correct rights to do this. However, I'm not sure if this is true.

Access :: IIS_WPG Write/modify Access To The Folder Where MS-Access Database Is Located - Insert An Error Pop-up?

Feb 17, 2010

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.

Web Forms :: How To Access The Contents Of A Column In Every Row Of A Table

Mar 5, 2011

I need to populate a listbox with the contents of a column in every row of a table. But, the table and its columns are only known at runtime. Once a table is selected by the user, I will know the name and type of the column, whose contents I need to display in a listbox. But, how do you access all rows of a table sequentially so that the contents of the column in each row can be added to the listbox?

DataSource Controls :: Access Time In A Column Of A Table?

Jun 25, 2010

I am able to store the current time of day in a column defined as time with the C# code as:notestable.NoteTime = DateTime.Now.TimeOfDay;The hour, minutes, seconds, and even millionth of a second is stored. But now, I need to retrieve the time and convert it into a string. I tried to use DateTime statements to accomplish this as with:

DateTime nt = notestable.NoteTime;
String FirstT = nt.Hour.ToString() + ":" + nt.Minute.ToString().PadLeft(2, '0');

Regarding the 'nt' variable, I got an error message that said: Cannot implicitly convert type 'System.TimeSpan?' to 'System.DateTime'.Regarding the 'Hour' designation, I changed the definition of 'nt' to 'var' and got an error message that said: System.Nullible<System.TimeSpan>' does not contain a definition for 'Hour' and no extension method could be found.So, how do I access the time from a table and convert it into a string for display in a TextBox?

Access A Database Table Multiple Times For Every Request?

Mar 16, 2011

A class in my ASP.NET website needs to access a database table multiple times for every request. The database table should rarely change, if ever. Maybe a couple times a month.

In the static constructor of the class, the table is fetched from the DB and cached in a static local variable. Whenever the class needs to access the table, then, it just uses the cached, static version.

My question concerns the lifespan of this cached, static version of the table.

I understand that it's fetched the first time the class is instantiated or a static method in the class is used. But how often does this occur on the web server? What if the table changes and we want to reset this static version of the table?

Basically, I'm wondering, is this table fetched once and then only refetched each time I restart IIS? What, with regard to the site and IIS, will trigger this static class to reset, causing the static table to be refetched?

Access :: Random Order Display In Datalist And Gridview From Access Database

Jul 8, 2010

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.

DataSource Controls :: How To Access Database Once With Big Resultset Or Access Multiple Times On The Fly

Jun 17, 2010

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.
