Using Terminal Services and RemoteApp to Extend Your Microsoft Access and other Windows Applications Over the Internet

Terminal Services RemoteApp and Microsoft AccessRead our new paper on using Terminal Services and RemoteApp to Extend Microsoft Access and Other Windows Applications Over the Internet.

One of the features of Microsoft Windows Server that is increasingly popular over the last few years is the Terminal Server and more recently RemoteApp. With few exceptions, most Windows applications work within a Terminal Server environment. By doing so, your investment in existing applications, and the power of Windows desktop features and interoperability, can be exposed over the Internet.

This is particularly powerful for database applications such as Microsoft Access since it eliminates the need to send large amounts of data over the Internet for Access to process and users do not need to install Access on their machine. With RemoteApp, you can set up a terminal server experience where your users can only run your application without running other applications or browsing your network. Easily web enable all your desktop applications.

Avoid Using DoEvents to Wait in Microsoft Access, VBA, and VB6

In our Microsoft Access, VBA, and VB6 programs, we often need to pauseprocessing for a certain period of time, or until a specific time, and thencontinue processing. One common way to do this is to use the DoEvents function in a loop whilewaiting, however, this method consumes the CPU time and slows down the PCconsiderably. This is a significant problem when pausing for more than a coupleof seconds, when users will notice the slowdown. Use the Sleep command instead.

Starting an AutoNumber Field in MS Access with a Number You Want

In Microsoft Access tables, the AutoNumber field type allows you to automatically assign a unique sequential number to each row in a table. AutoNumber fields are often used as the Primary Key, since they are unique and permanent.

By default, AutoNumber begins with 1. However, you may want to start with another number. Here's an easy way to set the AutoNumber at a number higher than 1.

Office Tip: Introducing Microsoft Office/Access 2010 and SkyDrive

Microsoft Access 2010The release candidate of Office 2010 is now available, and Office 2010 is expected to be shipping by mid-year. Hopefully you take the chance to download it, or at least review some of the many videos and articles about the new features.

For Access enthusiasts, the new version makes Access even more accessible to non-developers by exposing more functionality without requiring code or queries. For example, Reports are much richer, with added calculation tools and the ability to combine data from multiple sources. Microsoft has also created a whole new set of Templates to get users started more quickly, and what can be characterized as data triggers for Jet databases.

Most interesting is the ability to create solutions that can be exposed to the web. There are lots of restrictions and it’s not the same as putting an existing Access application on the web, but by leveraging SharePoint and cloud computing, it’s a whole new option for Access users and developers.

Part of Office 2010 is the Office Web Applications (OWA), a web version of Excel, PowerPoint, Word programs that allows you to create, edit and host Office files on the web without having Office installed locally. Microsoft is actually providing 25GB of space for you for free on their new SkyDrive site (with you Microsoft Live account).

Note: After losing a court case in the UK, Microsoft has renamed SkyDrive to OneDrive.
