TreeAge Pro – Object Interface

The TreeAge Pro 2007 Object Interface

The TreeAge Pro 2007 Object Interface allows you to manipulate trees and run analyses using program scripts rather than via the user interface.

For example, you could write a script to open a tree, modify some variable values, run a cost-effectiveness analysis, and place the output from that analysis in an Excel workbook.

You could also use the Object Interface to automate analysis execution and results handling. Then you could run a set of long analyses overnight and review the output in the morning.

Requirements

In order to use the TreeAge Pro 2007 Object Interface, you must have...

TreeAge Pro 2007 Excel or TreeAge Pro 2007 Suite installed and authorized.
Each product includes the Excel Module.
A working knowledge of scripting techniques/languages.
In our examples, we will use Visual Basic within Microsoft Excel.
A reference to the TreeAge Pro 2007 object library in your development environment.
In the Microsoft Visual Basic Editor, select Tools>References.
Then check the box labeled "TreeAge Pro 2007.1.0 Type Library". See below.

Object Documentation

Documentation of the TreeAge Objects and their methods and properties is available online.

Using the Object Interface

The TreeAge Pro Object Interface facilitates automation by allowing you to instantiate TreeAge Objects within a script. Then you can modify the objects' properties and use them to run analyses.

Here are a few of the objects that are available for your use.

Object	Description
ApplicationObj	Controls access to TreeAge Pro documents
TreeObj	Wrapper around tree document
NodeObj	Wrapper for a single tree node
CEOutput	Output of a C/E analysis
GraphObj	Wrapper for a graph
TextReportObj	Provide access to output of analyses
MarkovOutput	Output of a Markov analysis
MonteParams	Parameters for a Monte Carlo simulation
MonteOutput	Output of a Monte Carlo simulation

Chapter 30 from the User's Manual provides additional information about using the TreeAge Pro Objects.

Samples and Demos

To help you use the TreeAge Object Interface, we have provided presentation slides, a flash demo and a few Excel workbooks that include sample code for creating and using the TreeAge Pro objects.

This presentation handout describe the Object Interface and its capabilities.
This includes an example workbook that performs the following functions:

Open TreeAge Pro.
Open a model.
Set parameters using data from Excel.
Calculate Expected Value.
Change payoff set.
Run a Monte Carlo Simulation.
Run a Markov Cohort Analysis.

This flash presentation describes how to create simple macros that use the TreeAge Pro Objects.
This sample Excel workbook is used in the flash demo above. It contains Visual Basic macros that run a Monte Carlo simulation and place its output within the workbook.
This sample Excel workbook demonstrates the use of Monte Carlo batch event callbacks.
This sample Excel workbook demonstrates the use of Markov cycle event callbacks.
