Drag powerpoint slide to an external application

I am working on a new application and I would like to be able to drag and
drop slides from powerpoint into my application. Are there any examples of
how to do this? Do I need to write some kind of COM add-in to make this
happen or can it all be done from the clipboard? I am planning to develop my
application in csharp. Is there any reason that this wouldn't work?

Thanks,

Joe
 
I have a similar issue - I've gotten this far, if someone could offer up
the next level of detail...

In my target external app - I setup a simple drag/drop control - and
wanted to see if I could get at the slide being dropped off. I selected
a slide from the slide-sorter, and drag/drop it on a textbox control as
a test.

The list of GetFormats shows the following:
Embedded Object
Object Descriptor
EnhancedMetafile
MetaFilePict
Link Source
Link Source Descriptor
<< this next guy looks interesting,but how do I use it?
PowerPoint 8.0 Internal Slides
ActiveClipboard

....
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;

using System.Diagnostics;

using PowerPoint = Microsoft.Office.Interop.PowerPoint;
using System.Runtime.InteropServices.ComTypes;
namespace MyNS.Designer
{
public partial class TestPanel : UserControl
{
// ...snip - normal form/usercontrol stuff...

private void textBox1_DragDrop(object sender, DragEventArgs e)
{
bool test;
string[] fmts = e.Data.GetFormats();
foreach (string s in fmts)
Debug.WriteLine(s);

DataFormats.Format myFormat = DataFormats.GetFormat("PowerPoint
8.0 Internal Slides");
if (e.Data.GetDataPresent(myFormat.Name))
{
// should be a valid format string...
Debug.WriteLine("GetDataPresent for " + myFormat.Name);
}
// so now how do I get the ppt.slide I just did a drag&drop with?
}
}
 
It seems that you'd first have to write an application that can interpret and
display Slide data (iow, reproduce a great deal of PowerPoint itself, or at least
the viewer).

Depending on what you're after, could you use a bitmap or EMF? It should be
possible to write code to drop one of these into e.g. a picture box control (not
sure what a textbox would make of a graphic though <g>)

EO or EMF might be something - if in the end I could extract the SlideID
value - I'd be good to go. Agree however, textbox control is contrived
for the sample code - just for demo drag/drop & show the slideID value
of the slide.

I do have the Powerpoint PIA ala "using PowerPoint =
Microsoft.Office.Interop.PowerPoint;", my thought was this gives about
as much of Powerpoint & related functionality as one could expect to
get. (i.e. I can create & modify slides, create new presentations, save,
delete, yada, yada).

Given we do have the actual PP object types, there isn't any way to cast
the data payload and a Slide or Slides object? (Esp since one of the
formats alludes to notion that the data object is some sort of Slide.)

I doubt you'd be able to do that; the EMF wouldn't "know" where it came from, I don't
think.
Agree however, textbox control is contrived

OK, I see.
I do have the Powerpoint PIA ala "using PowerPoint =
Microsoft.Office.Interop.PowerPoint;", my thought was this gives about
as much of Powerpoint & related functionality as one could expect to
get. (i.e. I can create & modify slides, create new presentations, save,
delete, yada, yada).

But that's by automating PPT itself, no?

A slide, sure, but in a private clipboard format that probably only PPT understands.
