Which version of QPL are you using ?

Which compiler / language are you using ? C#, VB6, C++, Delphi ?

Do you have some sample code you can share >

I use the 5.11 version under visual studio 2008 C++
sample code :
   BOOL bIsLicensing = FALSE;
LONG lRet = -1;
    CQuickPDF* m_pQuickPDFObject = new CQuickPDF();
    if(m_pQuickPDFObject)
    {
        try
        {
            if(m_pQuickPDFObject->CreateDispatch("iSED.QuickPDF"))
            {
                bIsLicensing = m_pQuickPDFObject->UnlockKey("xxxxxx");//where xxx is remplaced by our licence
            }
        }
        catch(...)
        {
            ASSERT(FALSE);
        }

    }
        if(bIsLicensing)
        {
            lRet= m_pQuickPDFObject->LoadFromString((LPCSTR)(LPCTSTR)strPDFFromXML, strPDFFromXML.GetLength());
         }
        delete(m_pQuickPDFObject);
        m_pQuickPDFObject= 0;

QPL 5.11 is getting quite old.

You may want to read this post which will give you some clues to using LoadFromString. Hopefully the QPLBuffer functions are available.
