OleUIPasteSpecial - list box is empty

From my reading of the documentation, thecode snippet below should display a Paste Special dialog,
and if some text is currently pasted on the clipboard then "Unformatted Text" should appear
in the list of options to select from. But the list is empty! Can anyone please tell me
what I'm overlooking.

A mini Visual Studio project is available for download - http://www.deskmates.com/dl/TestPasteSpecial1.zip

void PasteSpecial(HWND hWnd)
{
OLEUIPASTEENTRY vPasteEntry[1];
vPasteEntry[0].fmtetc.cfFormat = CF_TEXT;
vPasteEntry[0].fmtetc.dwAspect = DVASPECT_CONTENT;
vPasteEntry[0].fmtetc.lindex = -1;
vPasteEntry[0].fmtetc.tymed = TYMED_HGLOBAL;
vPasteEntry[0].lpstrFormatName = "Unformatted Text";
vPasteEntry[0].lpstrResultText = "text without any formatting";
vPasteEntry[0].dwFlags = OLEUIPASTE_PASTEONLY;

unsigned int vLinkTypes[1];

OLEUIPASTESPECIAL o;
ZeroMemory(&o,sizeof(o));
o.cbStruct = sizeof(OLEUIPASTESPECIAL);
o.dwFlags = PSF_STAYONCLIPBOARDCHANGE;
o.hWndOwner = hWnd;
o.arrPasteEntries = vPasteEntry;
o.cPasteEntries = 1;
o.arrLinkTypes = vLinkTypes;
o.lpfnHook = MyHook;
::OleUIPasteSpecial(&o);
}

What is the return value of 'OleUIPasteSpecial()'? There are more than 10(!) error codes that this API might return. Why not make life easier and check them?

This was a cut down example to demonstrate the problem.
The dialog returns OLEUI_CANCEL meaning the cancel button was pressed,
which one would expect given that the OK button is greyed out because
are no options to select from in the list box.
