Access :: Database For Reference Value Maintainance?
Jan 30, 2010
I am building a small site for a local charity, it is quite simple and is using an access database.The database is mainly used for a simple poll/survey on the site as well as controlling the values for a couple of dropdown menus on the site.At the moment I have built a couple in the access database to enable to charity to maintain these reference values and survey as they have their own web server and have direct access to the web folder in their office.I was just wondering if anyone thought this was the best way to do this or if anyone else had any good examples of how to maintain a couple of reference values/surveys?

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 am making a simple ASP.NET webpage for my school organization using VS2010. When I choose "New Website," I see that Visual Studio already sets up a database for managing memberships. I also have my own database (MyDatabase) that I need to use for the site, which contains information about the members of the organization (for example, email, phone-number, etc.)
I need to have a way to find out who the current logged-in user is, and allow them to edit ONLY their information (email, phone-number).The way I have considered doing it is:
- Add a field in MyDatabase called "UserName" and use it as a sort-of foreign key from the other database.
- Get the username of the logged-in user
- Use this username for my queries For example:
// (PseudoCode)
String loggedInUser = MembersDatbase.GetLoggedInUser();
var MemberInfo = SELECT * FROM MyDatabase.Users WHERE UserName=loggedInUser;
-Then the logged-in user will only have access to their information.
I'm not sure about the code yet, but I could probably figure that part out. I'm more interested in hearing if there is a better way of doing this. I do NOT want to merge the two databases into a single database.

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 have a data type mismatch while inserting into a number field in an access database using a parameterized query.I think this should be pretty simple but I am still learning a lot.
[Code]....
I have some commented out as I am working one field at a time. The working fields are textboxes and the non working ones are dropdown lists. But I think it may be the field that the list is drawing from? Not sure.

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.

I am trying to add a web reference to my project in Visual Studio 2010 that points to PayPal's Sandbox service.
The address is [URL]
Although VS finds it using the Add Web Reference dialog box, when I press the Add Reference button I get the following error and it fails:
Failed to add Web Reference 'com.paypal.sandbox.www'.
Error: Access to the path 'C:Documents and SettingsMyNameLocal SettingsTempPayPalSvc.wsdl' is denied.
Even if I attempt this using http instead of https it still fails with the same error.

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.
This is my code:
[Code]....
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.
