External Action Demo

Tango External actions allow you to call DLLs you write from application files. You can pass data to the DLLs and get results back. Results HTML can be processed in a Tango <@ROWS> block using <@COL> tags.

See the header file provided for details on the functions that Tango External actions expect to be available in your DLL. More information is also available in Appendix D of the User's Guide (also available in the online help).

This directory contains four files in addition to this one:

EXTSRC.H - A header file to use in creating DLLs which will work with Tango's External action.

EXT_DEMO.CPP - C++ source code for a very simple example DLL.

EXT_DEMO.DLL - The compiled demo DLL.

EXT_DEMO.TAF - A Tango application file which calls the DLL via an External action.
