Error When Copying from Clipboard to PowerPoint Slide

[Ata]

Hello,

I am trying to copy the contents of the output of SQL Reporting Services to
a PowerPoint slide. For this, I am using SQL Reporting Services to obtain an
IMAGE stream, which I paste to the Windows clipboard. Then, using automation,
I am trying to copy this information from the clipboard to a PowerPoint
slide. However, I get an error at slide.Shapes.PasteSpecial.

I am able create a System.Drawing.Bitmap object from the memory stream that
I associate with the image stream. I can also copy an image fragment that I
clipped in MSPaint (which means it's on the clipboard) to PowerPoint using
Automation. And if I generate a CSV stream from Reporting Services, I can
copy this to the clipboard and from there to Excel. It's only that I don't
seem to be able to copy anything from the clipboard to PowerPoint if I pasted
it to the clipboard using the MemoryStream.

Does anyone have any pointers?

Thanks,
Ajay.
