Web Form OleDbException (0x80004005): Disk Or Network Error.]

Hi Everyone,

Hope you don€™t mind helping.

I am actually following exactly the example given in Karl Moore€™s €˜The Ultimate VB.net and ASP.net Code Book€™, ISBN 1-59059-106-2, Chapter 4, pp 141€¦

I am using VB.Net 2002 and create a Web Form, placing on it a Data Adapter, Connector and Dataset and link this to a Data Grid. The database is a quite large (150 Mb) Access 97 db that is shared over a network and the Provider is a Microsoft.Jet.OLEDB.4.0 connection. While in designer mode I can create the Dataset and even preview the data itself from the menu. When I run the project, the Web Form displays, connects to the Site (via IIS 5.1) but then the following error text is thrown all over the form:

Server Error in '/WebApplication3' Application.



Disk or network error.
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: Disk or network error.

Version Information: Microsoft .NET Framework Version:1.1.4322.2032; ASP.NET Version:1.1.4322.2032

I have read and implemented the articles in the KB about setting up System TEMP variables and changing their rights and also setting up the ODBC key in the registry but these make no difference however I change them. I have also tried copying the database to the local machine, again to no avail.

The versions of the system I am using are:

Microsoft Visual Basic .NET 55524-640-5065381-18871
Microsoft Visual Studio .NET 2002 Service Pack 1 (KB837234)
Microsoft Developer Environment 2002 7.0.9955

I have no idea why what should be a very simple thing just fails so catastrophically. I am tempted to move to VB 2005 but if anyone can shed light on the problem I should be most grateful.

Many thanks for your time and Energy.
