Total Access Statistics Update for Microsoft Access 2010, 2007, and 2003

Microsoft Access 2010

We are very pleased to release an update to Total Access Statistics for Microsoft Access 2010, 2007, and 2003. If you are an owner of version 14.0, 12.8, and 11.8 respectively, you can download the update at no charge.

Total Access Statistics is the most popular data analysis program for Microsoft Access. It extends the data analysis capabilities of Access queries to let you perform advanced numerical analysis on your data. Use any Access table, linked table, or query to perform calculations such as percentiles, regressions, frequency distributions, t-Tests, correlations, non-parametrics, rankings, moving averages, etc. It can also perform data normalization and let you select random records. As you would expect in a query, you can specify Group By fields so analysis is performed on each set of records with identical group fields. Total Access Statistics runs within Access with all output in Access tables. It supports MDB, ACCDB, and ADP databases.

The update includes these enhancements:

  • Significant performance improvements when processing large numbers of records
  • While analyzing records, a new status form appears with an option to cancel the process
  • Setup program offers machine or current user installation options
  • Resolves all known issues

Microsoft Windows Common Control Library (MSCOMCTL.OCX) Security Update Requires Fixing

ActiveX ControlOn August 14, 2012, Microsoft released a security update for Microsoft Office that includes an update to the Windows Common Control MSCOMCTL.OCX.

Unfortunately, this update causes problems with existing Microsoft Access, Visual Basic 6, and other applications that use the common control such as the Treeview and ListBox controls. For us, this impacts our Total Access Analyzer program which uses the Treeview control in its database explorer feature. It triggers this error:

Error 459 – Object or class does not support the set of events,
Procedure clsFrmExplorer_TAA.InitForm

Microsoft provides a workaround for this problem in a Knowledgebase article, but it doesn't always work. We've come up with a solution that addresses this problem reliably.

Read our article Fixing the Microsoft Windows Common Control Library (MSCOMCTL.OCX) Security Update for more details.

Microsoft Access Database Scalability: How many users can it support?

Microsoft Access 2013What’s the Maximum Number of Microsoft Access Users?

There is a persistent myth that Microsoft Access Jet databases can only support 20 or so users. Here’s my response to a recent inquiry:

I flatly refute any suggestions that Microsoft Access users are limited to around 30. We’ve run many tests and have never seen that kind of degradation in performance. It is a myth from Access 2.0 days that was eliminated with Access 97 almost two decades ago.

A poorly designed Access database won’t support two users, but a well designed Access solution can support hundreds of users. Of course, what matters is the number of simultaneous users, and what they’re doing.

At Least 200 Simultaneous Microsoft Access Users on an Access/Jet Database

If everyone is just viewing data or entering data into a table, that takes very little work and a large number of people (well over 200) can be supported. People cannot type faster than what Access can handle. If users are all running massive reports and queries with data updates, that can still be done but performance would be an issue which applies to any technology, so testing and optimization would be necessary.

Migrate Back-End Access Database to Microsoft SQL Server for More Users

Microsoft SQL ServerIf the back-end database is in SQL Server rather than an Access/Jet database, the number of users can be practically unlimited if each user has their own front-end copy of the Access application. Performance issues still apply based on what they are doing. In some cases SQL Server is slower than Access, so it is important to understand the situation before thinking SQL Server is the answer.

All that said, any Access application that is distributed to others with shared data should be a split database design. Here are a few resources we’ve written:

Total Access StartupSimplify Support for All the Users of Your Access Databases

We offer a commercial product for enterprises, Total Access Startup, that helps with the distribution of databases to each user’s desktop, and launching it with the right version of Microsoft Access.

This allows you to centrally support a large number of Access users across your network and ensure everyone is using the latest version of your application. It also simplifies the migration from one version of Access to another.
