How does one repeatedly show/hide a given presentation?

I posted an earlier question about toggling the read-only state of a
presentation, this post is similar.

From within our application, I would like to be able to repeatedly toggle
the visible state of a PowerPoint presentation.

To open the presentation in a "hidden" state, I can make this call:

pptPres = ppApp.Presentations.Open ("path to PPT",
msoFalse, // allow changes
msoFalse, // not untitled
msoFalse); // without window

To make the presentation visible, I can make this call:

pptPres.NewWindow();

If I want to toggle it to hidden again, it seems that my only option is to
close the window:

pptPres.Windows.Item(1).Close();

At this point, I'm stuck - because closing the last window for a
presentation will close the entire presentation. Any references to this
object are invalid.

Starting with an open presentation, it seems that this is my only option for
repeatedly hiding and showing the PPT:

a) Hide: Close the presentation, open with no window
b) Show: Call ppt.NewWindow()
c) goto a

Is there any other way to repeatedly show and hide a given presentation?

Sorry, no can do. You can minimize the window, but you cannot close it w/o
closing the presentation. Your only way is to close and reopen at this point.

I had basically come to the same conclusion myself. Unfortunately, I have
gotten spoiled on the Word object model and am finding the PowerPoint objects
to be *considerably* less powerful. Do you know if there are any plans to
bring the PowerPoint object model up to the level of Word?

You are absolutly right. The PPT object model is inferior to Word and Excel.
That is because there are many less people automating PPT then Word and Excel.
With each realease, we are getting better, but Word and Excel will always
have a better OM. That's life...
