Menu Path

Tools->Register Custom Decode

Purpose

Observer allows you to write your own protocol decoder, assuming that you have expert

knowledge in the following:

• The protocol you are writing the decoder for

• The C++ Programming Language

In addition, it helps if you have Microsoft C++ Developer's Studio, as Network

Instruments has included an example project file for that environment along with the

example source code. The Custom Decode Kit is contained in the Observer

Files\Drivers\CustomDecodeKit directory (CustomDecodeKit.exe, which is a self-

extracting archive). Along with the example project and source files, the Kit also includes

an Acrobat PDF file that outlines the steps in building a DLL.

Once you have built a DLL and placed it in the Observer FIles directory, select Register

Custom DLL from the Tools menu and add the new DLL to the list of registered DLLs.

Once a DLL has been registered, the new decode will be available in the Decode and

Analysis tree control.
