dataobject and rtf/html conversion

[New World Order Pigs]

I am trying to use dataobjects class to convert rtf to html and back to rtf
again and I can't get it to work. Below is the code...

IDataObject data = new DataObject();
dataSetDate(DataFormats.Rtf,true,strRTF);
if (data.GetDataPresetn(DataFormats.Html,true))
{
strHTML = data.GetData(DataFormats.Html,true).ToString();
}
else
{
// return the formats available code
}

When this code executes it just returns RTF as the only format available.
The implications of the documentation for DataObject is that it does
conversions between common formats and yet it doesn't seem to be doing it at
all. If I use the clipboard to try to do this with DataObject then it only
sees it as Unicode Text even though it is RTF. Does anyone have any ideas
about whether this can work? The documentation seems to strongly imply that
it should.

Thanks,
NWOP.
