Welcome to "Delphi Labs"! There is so much fun researching different areas of DataSnap architecture. The episode this week is about different application types. The last tutorial was quite complex, so this time I wanted to keep the demo part really simple.
Different types of DataSnap servers are very nicely explained by Jim Tierney at his CodeRage5 conference episode and available at the channel-e.
The step-by-step demo in this tutorial is focused on implementing and installing Delphi DataSnap server, which is a Windows Service application. This scenario is very useful when your services are deployed in the cloud and new machine images are started and stopped automatically by a load balancer.
Enjoy!

Mr. Pawel Glowacki,
In this Delphi Labs episode "Building the Server as Windows Service" for Delphi XE3, is possible to include a form that is visible on the server? (Win7 or Win8)
For example: Showing Service status (running, stopped or suspended) or if the database is connected.
Hi Alexandre,
Yes. It should be easily possible to add a visible form to the Windows service
Pawel
Hi Pawel,
I added a form visible on server and performed normally on windows XP, but even when running a server on windows 7 the form is not visible, but I see in task manager that the server is running. Even I can connect the client and seek information from the database.
Why the form is not visible?
Alexandre
