I create a Powerpoint automation test program following

How to create an automation project using MFC and a type library
But get serious trouble when it parses only a single rectange shape in a
simple single PPT slide

The proble is always get assertion in "pptApp.put_Visible(false);"
"long nCount = shapepts.get_Count(); "
" long n = gshapes.get_Count(); "

Also I get assertion if I call shape.get_Vertice()

I ugently need the help to solve this problem.

the code is:

#include "stdafx.h"
#include "testPPT.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#endif

I don't do C but it seems you're trying to get properties of a rectangle that
don't exist.

Rectangles don't have a nodes collection and there are no vertices.

A shape that's not .Type = 6 (group) won't have GroupItems and because of that,
no GroupItems.Count



CShapeNodes shapepts = shape.get_Nodes();
long nCount = shapepts.get_Count(); //Get Assertion
CGroupShapes gshapes = shape.get_GroupItems();
long n = gshapes.get_Count(); //Get Assertion
