Default Accessing an online Access database with ASP.NET

Hi all, I hope this is the right forum to place this.

I'm new to ASP.Net, I have created an ASP.Net Website using Visual Studio 2010. The website accesses a Microsoft Access database to delete, select and insert information. It works fine when it runs on my PC. However, some problems occur when I host it online. When the website loads, it immediately has to delete any entries in a certain table; however this error message appears:

Could not delete from specified tables.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.OleDb.OleDbException: Could not delete from specified tables.

Source Error:

Line 113: Dim deleteQTableSQL As String = "DELETE * From QuestionsAsked"
Line 114: Dim deleteCMD As New OleDbCommand(deleteQTableSQL, CAToleDbConn)
Line 115: deleteCMD.ExecuteNonQuery()
Line 116: End Sub
Line 117:

Source File: c:\inetpub\wwwroot\ap04aaa\CatTest.aspx.vb Line: 115

Stack Trace:

System.Web.UI.Control.LoadRecursive() +74
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +2207

The connection string I used to access the database is:

<add name="CATCS" connectionString="Provider=Microsoft.ACE.OLEDB.12. 0;Data Source=|DataDirectory|\CATDB.accdb;" providerName="System.Data.OleDb"/>

Does anyone know what I doing wrong? I went through a guide to ensure that my folders are configured with IIS to ensure that there are enough permissions. I am able to run a hosted website that doesn't contain a database fine, but the above error message appears with my website that uses an Access database.

Thanks in advance

Hi again, I figured it out. It turns out only 1 of my online folders had the write permission. Hence, i couldn't insert/delete in the others but only read. I moved the db to the folder with the write permission, edited the connection string accordingly and it started working.
