COM/DCOM Protocol Overview

When you record COM client applications, VuGen generates functions that describe COM client-server activity. The recorded script contains interface declarations, API calls and instance calls to methods. Each COM function begins with an lrc prefix. You can configure the programming language in which to create a Vuser script as either C or Visual Basic.

For each COM/DCOM Vuser script, VuGen creates the following:

  • Interface pointer and other variable declarations in the interfaces.h file.

  • Function calls that you can record in the vuser_init, actions or vuser_end sections of the Vuser file.

  • A user.h file containing the translation of the Vuser script into low level calls.
