Storing Files and Images in Access with ASP.NET

Sunday, December 6, 2009 7:46 PM

MS Access ASP.NET 3.5 ASP.NET Web Forms

Should you store files and images in the database or the filesystem in an ASP.NET application?  With SQL Server this is a dilemma, with both approaches having their pros and cons.  When it comes to Access, the decision is much easier to make.  Because an Access database is restricted to 2Gb, it makes more sense to store files in the file system.  However, sometimes, you may not have the choice. If you have to use the database, here's how.

Wednesday, April 30, 2008 10:48 PM

ASP.NET 2.0 MS Access ADO.NET ASP.NET 3.5

The unbelievably cryptic Operation Must Use An Updateable Query error is the bane of developers who are just starting out with Access and ASP.NET. You've done your code, plopped your database file in the App_Data folder (or at least, you should have done), and try to run a page that INSERTs or UPDATEs records, and it all stops dead. This brief article explains the cause of the error, and the steps required to stop it recurring.

Migrating from Sql Server to Access in ASP.NET

Friday, November 16, 2007 10:45 AM

MS Access ADO.NET

Yes, you did read that correctly. Here's the situation: you know that Sql Server is by far the superior database system (if indeed MS Access can be called a database system). You also know that MS Access databases are not recommended as a data store for web applications. You are comfortable with Sql Server, and haven't really looked at Access for years - if at all. But now, your boss or your client wants you to use it in the next project.

An ASP.NET Search Engine with MS Access for optional search criteria

Monday, November 12, 2007 3:15 PM

ASP.NET 2.0 MS Access ADO.NET ASP.NET Web Forms

Creating a search interface for one user-supplied value is pretty straightforward: a TextBox for input, a Button and some SQL that searches one or more fields where the values are LIKE '%' + @searchterm + '%' is all that is needed. While it works, this approach is not very flexible. For example, what if you wanted to search for an Employee whose last name contains "a", and don't want those where the first name or city contains "a"? The traditional solution to this is to dynamically construct the SQL statement based on what values were passed by the user. However, building the SQL string can get repetitive, boring and messy. Here is a cleaner way to allow the user to narrow down searches across multiple criteria with the use of optional parameters, and just 3 lines of programming code.
