Get serious trouble in Powerpoint automation code

Z

Zhaohui Xing

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:

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

Zhaohui Xing,

I'm currently trying to automate Powerpoint and I've added the various
classes needed, but I can't get it to compile when I add them to my
application. I'm having issue with MsoRGBType and various others. What am I
missing?

Zhaohui Xing

Try the following in stdafx.h or other header file

#import "mso.dll" rename ("RGB", "RGBMSO")

Zhaohui Xing,

I'm currently trying to automate Powerpoint and I've added the various
classes needed, but I can't get it to compile when I add them to my
application. I'm having issue with MsoRGBType and various others. What am
I
missing?

Zhaohui Xing said:
Thanks!

Steve Rindsberg said:
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

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

#include <afxdisp.h>
