shape.Parent doesn't return Slide

In most cases shape.Parent is the slide that contains the shape.

However, if you try to delete a a group and then press on undo (the shapes will reappear) but the child shapes will throw exception for both .Pa开发者_开发百科rent and .ParentGroup.

How can I find out the slide ID of a shape in the case above?

I did your instructions and didn't have any problems. I added two shapes to an emtpy blank slide and and then deleted them both at the same time and then did Ctrl+Z. then I ran this in the immediate window -

?ActivePresentation.Slides(1).Shapes(1).Parent.SlideIndex

And it worked and showed a value of 1.

So then I thought you had these as a group, so i grouped the two shapes and did the same as above. And it worked just fine.
