Change Your c-treeVCL c-tree Library to Client-Server

Borland’s Visual Component Library (VCL components) led the way in programmer productivity with superb drag and drop convenience within the integrated development design editor. FairCom has supported this concept with c-treeVCL components for rapid database development using c-tree in the Borland environment.

The c-treeVCL Components are installed with a simple installer. When a user installs c-treeVCL, they are asked “in which model they want to develop”, and are offered 2 choices, standalone or client/server. By default, they are given immediate access to a c-tree Server via the client option.

Many programmers begin with simple standalone applications. Frequently, these successful applications grow to multi-user enterprise applications requiring the full power of the c-tree Server. It is easy to switch the c-tree library required by the c-treeVCL components to make this change!

One simple way is to just quickly re-install the c-treeVCL components, selecting the appropriate option. This will have no other impact upon your installation. However, it is also a simple matter to edit the following registry entry:

HKEY_LOCAL_MACHINE\Software\FairCom\c-treeVCL\DllName

Simply reference ctclient.dll to use c-tree client/server mode or ctreestd.dll to use c-tree standalone mode. You can immediately begin using the c-treeVCL components with this referenced model.

For over fifteen years National Public Radio has controlled and managed its entire satellite network radio broadcasts with an application built by Chesapeake Computer Group with FairCom's database technology. This system controls audio routing switchers, makes contact closures for tape recording machine starts and On-Air and Warning lights, controls transmitter parameters, digital audio storage systems and other devices required to operate its broadcasting network.

FairCom's technology provides the performance and stability required to capture and process the data used to operate and control an international satellite communications system. An application such as this requires absolute assurance that its database will provide the accuracy, data integrity, stability and performance required by the most demanding mission-critical embedded technology. In addition, FairCom's portability and scalability has allowed the NPR broadcast network to expand and move into the full international position it occupies today, providing radio network programming to every US military facility and many other international organizations world wide.
