And here is the code (attached) that I used to retrieve the clipboard
format info via IDataObject, in case someone is curious.

#include <Windows.h>

#include <iostream>
#include <cstdlib>

using namespace std;

int main()
{
    IDataObject* pData = NULL;
    HRESULT hr = OleGetClipboard(&pData);
    if (hr != S_OK)
    {
        cout << "failed to get the clipboard data object instance." << endl;
        return EXIT_FAILURE;
    }

    cout << "IDataObject = " << pData << endl;
    pData->AddRef();

    IEnumFORMATETC* pFormats = NULL;
    if (pData->EnumFormatEtc(DATADIR_GET, &pFormats) != S_OK)
    {
        cout << "failed to get available format types." << endl;
        return EXIT_FAILURE;
    }

    pFormats->AddRef();
    pFormats->Reset();
    FORMATETC fetc;
    while (S_FALSE != pFormats->Next(1, &fetc, NULL))
    {
        cout << "format code: " << fetc.cfFormat << endl;

        char name[100];
        int len = GetClipboardFormatName(fetc.cfFormat, name, 100);
        if (!len)
            continue;
        cout << "format name: " << name << endl;
    }

    pFormats->Release();
    pData->Release();

    return EXIT_SUCCESS;
}
